Is Diabetes the Disease or the Symptom – Huffington Post

Posted: March 25, 2017 at 7:40 pm

Earlier this week I was told I was diabetic. When sharing it with people, some felt maybe this was not the type of news the founder of Less Cancer should broadcast.

I am sure that it is exactly the kind of thing to share. Since founding the organization in 2004, I have always been open about some of the lifestyle challenges and risks I have engaged in; from being a chain smoker as a child to having a diet so poor that as a college student at 661/2 and 168 lbs, I was diagnosed with malnutrition.

Since that time I have been far from saved. I did quit smoking twenty-one years ago when my son was born, as he had a respiratory issue that would have prevented me from ever holding him. Fortunately, the doctor that was treating him at the time used his agency to say that I would have to leave my clothes outdoors and take a shower before picking him up. With the help of the patch, I quit right away.

Pancreatic cancer and diabetes have been linked in patients who have had diabetes for less than five years, yet it is unclear if diabetes contributed to the cancer or if the pre-cancerous cells caused the diabetes. Also, research suggests that new-onset diabetes in people over 50 may be an early symptom of pancreatic cancer. (Pancan.org) My sister died of pancreatic cancer at a young age.

Type 2 diabetes has a stronger link to family history and lineage than type 1, although it too depends on environmental factors. If there is a family history of type 2 diabetes, it may be difficult to figure out whether it is due to lifestyle factors or genetic susceptibility. I only know of a few family members with type 2 diabetes, and they were all at an enviably healthy weight.(Diabetes.org)

However, for over twenty years I have been vigilant about eating and serving certified organic foods to my family. For me, sugar is the head-spinning devil. And no matter how healthily I eat around it, its just too tough to burn off a slice of cake. I walk at least a few times a week, and I have started running on the treadmill with a trainer when I am back home in Virginia.

When I heard the news of my diagnosis, I felt ashamed as to how I could not know better. Certainly, I had been warned. I was most angry with myself because, with my very non-profit salary, I understood that I would never really be able to afford the meds for a diabetic. My doctor has given me three months to turn things around.

However there is something even more insidious, and that is isolation.

In my work, without intention or awareness, I seem to have systematically built a wall around myself to the outside world and my own personal needs.

I am immensely grateful for the handful of amazing friends and my immediate family, with whom I am in touch daily. But something strange began happening as I heard from more and more people that I did not know and started connecting with on social media, and then through blogs. In the course of the day, I often speak to more strangers than people I know. I am on the road so much that I often eat alone and have little social contact.

After the United States Congressional Caucus and the Cancer Prevention Workshop this past February, on the only free day I had I met with a few of the cyclists for the bike ride to raise money for Less Cancer. The day of my birthday in Detroitmy big nightwas spent on my laptop, in my hotel. I took a moment to check Facebook and email only to notice an embarrassing amount of birthday wishesbetween social media and email it was well into the hundreds.

As I drove out of town the next day, hurrying to my next stop, I could not help but think how strange it felt to look at all these communications from so many people I did not know-despite being very appreciated. I meet kind and wonderful people each day and I am one of those people that love others more than myself.

As more people get to know me and the work of Less Cancer, I receive accolades but not always from people I know. I feel a need to protect myself by establishing boundaries, thus creating even greater distance between me and the world.

Somehow the more I connect and work with the masses my wall, unseen by the outside seemingly inches higher, insidiously moving further away from filling my metaphoric bucket or addressing some very basic needs.

With a focus outwards on the rest of the world, I move further and further away from my needs.

In trying to understand my diabetes diagnosis, I find myself asking what isolation means to human healthworking alone, traveling alone, and frequently not having any connections beyond people who want to talk to me about my work.

In a report by Soledad OBrien, Surgeon General Dr. Vivek Murthy said the greatest public health crisis (according to the surgeon general) isnt cancer or heart disease. Its isolationisolation and the affects of being socially disconnected.

I may never know if my diagnosis is hereditary or lifestyle, stress or isolation. You can count on me turning my sights inward as a matter of health. Watching diet and exercise, connecting with friends and asking for help with the work for Less Cancer.

I will be exploring more about isolation as it impacts human health, including diabetes. Diabetes can, in fact, be a cancer risk. Now more than ever, we need to get a handle on these preventable diseases, and it needs to start with me.

Is this my legacy to my children? Is this what I leave thema future knowing that the idea of Less Cancer will be a missed opportunity to turn the steadily increasing incidences of cancer around. A future with a cancer economy?

I am not giving up-if you want to help, please help the work of Less Cancer not because of me but rather because we are doing life-saving work that is making change.

Discovery School walks the walk in Type 1 diabetes awareness … – Richland Source

Posted: March 25, 2017 at 7:40 pm

MANSFIELD -- Students at Discovery School are learning about Type 1 diabetes and the differences it has with Type 2.

Not only are the students talking the talk -- they are walking the walk. Discovery School's student body will hold a Kids Walk for Type 1 Diabetes March 29 at 11:40 a.m.

The event was sparked when student Jager Thornton, 4, was diagnosed with the disease.

Jarger's mother, Ashley Thornton said she wants to make sure people are aware of the differences between the two types, not "lumped together as one disease."

Type 1, or insulin-dependent diabetes is a chronic condition in which the body no longer creates its own insulin. Insulin is a hormone necessary for blood cells to create energy from consumed sugar.

Type 2 diabetes, a much more commonly-known version of diabetes, occurs when the body becomes resistant to insulin or doesn't make enough insulin, according to the Mayo Clinic.

"We've adjusted pretty well," Thornton said of her son's condition. "It's a lot of routine, finger pokes, loss of sleep. It was life altering. My son's life is now in the hands of his caretakers. If he get's too little insulin he could die."

Third grade teacher, Lindsay Wicker said allowing students to have an opportunity to take action is a emphasized mantra for students at Discovery School.

"I tell my students that all the time," Wicker said. "And when (Ashley) said she was wanting help raising awareness, I thought this would be a great opportunity to have my third-grade students to be able to take action for something important."

Wicker's students are reading facts about the disease during morning announcements, stuffed information about the disease into envelopes to spread to their peers and are helped organize the walk.

"It's a great opportunity to make a difference even though they are only in third grade," she said.

Discovery School has raised $500 for the JDRF, the leading global organization for Type 1 diabetes research, in the first week.

Students also were given three paper shoes to sell for any amount of money. The money will be donated to the JDRF Organization.

"It's impressive. They don't have to sell the shoes," Thornton said. "They have one more week (to raise money); they are on Spring Break right now."

Thornton said she is gratefulto Discovery School for its cooperation and willingness to teach students about the disease. She hopes the education will provide her son with the ability to fit in and feel like his classmates.

"One thing I want for Jager is more people to be aware of Type 1 of this disease," Thornton said. "I just wish people would learn there is more than (the Type 2 version), that it's not the same."

Field of biotechnology is ever expanding and evolving – BSI bureau (press release)

Posted: March 24, 2017 at 3:43 pm

Dr Kalpana Joshi shares her thoughts with BioSpectrum on current biotech education and the academia-industry gap

Dr Kalpana Joshi is Professor and Head of the Department of Biotechnology at Sinhgad College of Engineering (SCOE). The institute is affiliated to Savitribai Phule Pune University (SPPU) and recognised by All India Council for Technical Education (AICTE), New Delhi. Recently, SCOE has received NAAC "A" Grade. BTech Biotechnology course run by the department is first AICTE approved course in SPPU. Dr Joshi completed her doctorate in molecular biology from National Chemical Laboratory. She headed in-vitro biology group at Pharma R and D, besides giving consultancy to pharma companies like Glenmark, Matrix, Hyderabad and Orchids, Chennai. The SCOE department has a team of faculty with expertise in fermentation engineering, biochemical engineering, pharma biotechnology, biochemistry, analytical chemistry and microbiology. Faculty is active in fetching grants for research, patents and publications. Dr Joshi shares her thoughts with BioSpectrum on current biotech education and the academia-industry gap

Do you think biotech schools are teaching what industry needs?

Field of biotechnology is ever expanding and evolving. Pharma companies have diversified into production and business of biotherapeutics, vaccines and immunologicals, and molecular diagnostics. Industries such as agri-biotech, dairy biotech, food biotech are coming up and have specific requirement of skilled manpower. I feel giving hard core fundamental knowledge of the subjects and skill development are essential to meet industry requirement.

Specific requirements of industry when it comes to biotech education?

Industry requires experienced and trained manpower. There is no time for training in companies. I remember my former boss used to tell me Kalpana this is not university for training. Take someone who would work from the next day.' Biotech schools need to develop necessary laboratory skills and strong basics.

Where is the gap according to you?

As a manager in drug discovery R&D of top pharma company, I used to interview candidates from renowned biotech schools in India. Major observation was students lacked practical skills and basic knowledge of fundamental subjects like microbiology, immunology, molecular biology, biochemistry etc. We at SCOE decided to focus on developing strong knowledge and skills in three pillars of biotechnology namely microbiology, biochemistry, and molecular biology with blend of engineering fundamentals like mass transfer, heat transfer, unit operations, plant design and process development. We have created excellent facilities so that students get to handle top brand equipment like PCR, HPLC, Lyophiliser, fermenters, microfiltrations and develop practical skills in molecular biology, animal tissue culture and data analysis softwares. Gap is at many places. I can give examples. Students use graph papers to plot graphs. We need to train them to use Excel to analyse data and plot graphs using softwares like Prism and SPSS normally used by industries

What do you do to bridge the skill gap if it exists?

At Sinhgad Institutes, we have state-of-the-art laboratories where students are trained for developing practical skills in microbiology, enzymology, molecular biology, fermentations and reaction engineering. We also teach them computation and statistics. Students work on projects and develop skills in at least one technique such as PCR, HPLC or cell culture. They are trained to be analytical, logical and develop problem solving capacity. Students are encouraged to do industry internships and projects in collaboration with companies and national laboratories.

What has been the investment in student training?

We have invested in infrastructure, facilities, equipment and faculty. Faculty members are PhD/ MTechs from renowned institutes like NCL, IITs, ICTs with industry exposure. If faculty does not know what is happening in the industry then it is difficult to percolate it to students. We ensure that faculty gets exposure to industry and maintain interactions with industry experts

Karnataka’s biotechnology finishing school programme, five years on – BSI bureau (press release)

Posted: March 24, 2017 at 3:43 pm

Dr S Balasubramanya, BTFS Coordinator and Dr Mittur N Jagadish, Head-BioTech Facilitation Cell, KBITS, Government of Karnataka

Karnataka state has remained one of the major investment destinations in the biotech industry. Currently, the State of Karnataka contributes around 35 per cent of the Indian biotechnology sector. The state government has established Biotechnology Bio-Innovation Centre at Bengaluru Helix.

Theme-based biotech parks are at various stages of implementation in Bidar, Dharwad, Mangaluru and Mysuru. The state has already in place, multi-sector start-up policy with various industry specific incentives and ease of doing business measures to stimulate growth of industry in Karnataka.

Life Sciences Sector Skill Development Council (LSSSDC) has estimated life sciences industry which includes biotechnology industry to employ 1.5-1.6 million people by 2020. The sector is expected to see a possible supply gap upwards of 0.3-0.4 million, with the highest gap in the manufacturing segment.

The majority of full-time employees are distributed between marketing and manufacturing, and a limited number in R&D and other functions. Approximately, 40 per cent job roles are clustered at entry/junior level; 35 per cent at mid-level and 20 per cent at senior levels in the industry.

The junior and entry level positions that make up 40 per cent of the job roles requires attributes such as technical proficiency in laboratories, subject knowledge (basic and superior), high learning aptitude and thinking and questioning ability as key skills. Need is also felt for skill and capability building in Quality, IP and Regulatory aspects. Biotechnology industry in India is growing conservatively at 10 - 15 per cent and is said to be adding 15 to 20 per cent workforce to existing 50,000 jobs. The entry level jobs are 5 per cent of the 15 - 20 per cent workforce added each year.

The stem cell procedure that may change the sports medicine field in 2017 5 observations – Becker’s Orthopedic & Spine

Posted: March 24, 2017 at 3:42 pm

Physicians, healthcare professionals and members of the MLB community will keep a close eye on Red Sox pitcher Andrew Pomeranz's recovery from a potentially career-saving stem cell procedure, according to The Boston Globe.

Here are five things to know:

1. Steve Yoon, MD, of the Los Angeles-based Kerlan-Jobe Orthopaedic Clinic extracted bone marrow from Mr. Pomeranz's hip bone and back and injected it into his flexor tendon.

2. Mr. Pomeranz was motivated to undergo the procedure after fellow pitchers Garrett Richards and Andrew Heaney opted for the treatment instead of undergoing Tommy John Surgery to treat the partial tears in their ulnar collateral ligaments.

3. Lyle Cain, MD, of Birmingham, Ala.-based Andrews Sports Medicine & Orthopedic Center said, "Stem cells are a way to try to deliver the chemicals to cells and the chemical attractive factors to that area to allow the body to heal that tissue. That's what PRP was used for as well. Stem cells have more promise because not only do they have the chemicals that platelet-rich plasma has, but you're also putting some of the healing cells themselves in that area."

4. Pitcher Bartolo Colon was the first baseball player known to receive stem cell treatment when he received injections in his injured rotator cuff and elbow in the Dominican Republic in 2010. The 43-year-old pitcher's career was resurrected following the operation, partially prompting the method's increased popularity.

5. If Mr. Pomeranz has a successful 2017 season, the number of players undergoing stem cell procedures may rise.

Peptide targeting senescent cells restores stamina, fur, and kidney function in old mice – Medical Xpress

Posted: March 24, 2017 at 3:42 pm

Regular infusions of a peptide that can selectively seek out and destroy broken-down cells that hamper proper tissue renewal, called senescent cells, showed evidence of improving healthspan in naturally-aged mice and mice genetically engineered to rapidly age. The proof-of-concept study, published March 23 in Cell, found that an anti-senescent cell therapy could reverse age-related loss of fur, poor kidney function, and frailty. It is currently being tested whether the approach also extends lifespan, and human safety studies are being planned.

The peptide took over four years of trial and error to develop and builds on nearly a decade of research investigating vulnerabilities in senescent cells as a therapeutic option to combat some aspects of aging (Trends in Molecular Medicine, 10.1016/j.molmed.2016.11.006). It works by blocking the ability of a protein implicated in senescence, FOXO4, to tell another protein, p53, not to cause the cell to self-destruct. By interfering with the FOXO4-p53 crosstalk, the peptide causes senescent cells to go through apoptosis, or cell suicide.

"Only in senescent cells does this peptide cause cell death," says senior author Peter de Keizer, a researcher of aging at Erasmus University Medical Center in the Netherlands. "We treated mice for over 10 months, giving them infusions of the peptide three times a week, and we didn't see any obvious side effects. FOXO4 is barely expressed in non-senescent cells, so that makes the peptide interesting as the FOXO4-p53 interaction is especially relevant to senescent cells, but not normal cells."

Results appeared at different times over the course of treatment. Fast-aging mice with patches of missing fur began to recover their coats after 10 days. After about three weeks, fitness benefits began to show, with older mice running double the distance of their counterparts who did not receive the peptide. A month after treatment, aged mice showed an increase in markers indicating healthy kidney function.

Senescent cell therapy is one of several strategies being tested in mice aimed at reversing aging or lengthening healthspan. In 2015, the Valter Longo laboratory at the University of Southern California reported that mice on a calorie-restricted diet that mimics fasting benefited from a longer life, a reduction in inflammatory disease, and improved memory (Cell Metabolism, 10.1016/j.cmet.2015.05.012). And last December, Juan Carlos Izpisua Belmonte at the Salk Institute of Biological Science and colleagues made headlines with their discovery that cellular reprogramming of epigenetic marks could extend lifespan and improve health in fast-aging mice (Cell, 10.1016/j.cell.2016.11.052).

"This wave of research on how we can fight aging is complementary, and not in competition," says de Keizer. "The common thread I see for the future of anti-aging research is that there are three fronts in which we can improve: The prevention of cellular damage and senescence, safe therapeutic removal of senescent cells, to stimulate stem cellsno matter the strategyto improve tissue regeneration once senescence is removed."

de Keizer aims to start a company based on these findings, but in the short term, he and his group want to show that their peptide is non-toxic in humans with no unforeseen side effects. They plan to offer a safety clinical trial in people with Glioblastoma multiforme, an aggressive brain tumor, which also shows high levels of the biomarkers needed for this FOXO4 peptide to be effective.

Measuring Heart Toxicity of Cancer Drugs – Technology Networks

Posted: March 24, 2017 at 3:42 pm

Using human heart cells generated from adult stem cells, researchers have developed an index that may be used to determine how toxic a group of cancer drugs, called tyrosine kinase inhibitors (TKIs), are to human cells. While 26 TKIs are currently used to treat a variety of cancers, some can severely damage patients hearts, causing problems such as an irregular heartbeat or heart failure.

For the study, reported February 15 in Science Translational Medicine, the researchers used stem cell-derived heart cells from 13 volunteers to develop a cardiac safety index that measures the extent to which TKIs kill or alter the function of heart cells. They found that the TKIs' toxicity score on the index was generally consistent with what is known about each drug's heart-related side effects.

This work follows on the heels of an earlier study from the same research team, published in Nature Medicine, in which they assessed the heart cell toxicity of doxorubicin, a chemotherapy drug that also causes heart-related side effects, including heart failure. In that study, the researchers used stem cell-derived heart cells from women with breast cancer to correctly predict how sensitive each womans heart cells were to doxorubicin.

Such tests could ultimately help the pharmaceutical industry identify drugs that cause heart-related side effects earlier in the drug development process and help the Food and Drug Administration (FDA) during the drug review and approval process, said the study's senior author Joseph C. Wu, M.D., Ph.D., director of the Stanford Cardiovascular Institute.

I hope this research will be helpful for individual patients, once we further implement precision medicine approaches, he added.

Ranking Heart Toxicity

To assess the potential risk of heart toxicity for drugs in development, pharmaceutical companies use laboratory tests involving animals (usually rats or mice) or cells from animals or humans that are engineered to artificially express heart-related genes. Drug candidates that appear to have an acceptable balance of benefits and risks typically proceed to testing in human clinical trials.

But there can be biological differences between these existing models and humans, so non-clinical lab tests can have significant limitations, explained Dr. Wu.

Currently, the first time humans are exposed to a new drug is during clinical trials, he said. We think it would be great if you could actually expose patients heart, brain, liver, or kidney cells to a drug in the lab, prior to clinical treatment, allowing researchers to determine whether the drug has any toxic effects.

Dr. Wu, a cardiologist by training, studies toxicities cancer drugs cause in heart cells. Human heart muscle cells (called cardiomyocytes), however, are hard to obtainrequiring risky heart surgery that may be of no direct benefit to the patientand are notoriously difficult to grow in the lab.

As an alternative, researchers have developed a method to produce heart cells from human induced pluripotent stem cells (hiPSCs). hiPSCs are created by genetically engineering normal human skin or blood cells to express four specific genes that induce them to act like stem cells. Chemical treatments can prompt hiPSCs to develop into mature cell types, such as heart muscle cells.

A large body of research has established that human adult stem cell-derived heart cells, which function and grow in cell culture, can be used as an initial model to screen drug compounds for toxic effects on the heart, said Myrtle Davis, Ph.D., chief of the Toxicology and Pharmacology Branch of NCIs Division of Cancer Treatment and Diagnosis, who was not involved in the studies.

For the Science Translational Medicine study, Dr. Wu and his colleagues set out to determine if a panel of human stem cell-derived heart cells could be used to evaluate the heart toxicity of 21 different FDA-approved TKIs.

They generated hiPSC-derived heart endothelial, fibroblast, and muscle cells from 13 volunteers: 11 healthy individuals and 2 people with kidney cancer who were being treated with a TKI. Using drug concentrations equivalent to what patients receive, the investigators next determined how lethal each TKI was to the heart cells.

They found that several TKIs were very lethal to endothelial, fibroblast, and heart muscle cells from all 13 individuals, while others were more benign.

Stem cell-derived heart muscle cells grown in a dish spontaneously contract as a beating heart does, so the researchers also analyzed the effects of TKIs on the cells beat rate, or contractility. They found that several TKIs altered the cells beat rate before they were killed by the drug treatment. If severe enough, an irregular heartbeat (called an arrhythmia), can disrupt normal heart function.

From these lethality and contractility experiments, the team developed a cardiac safety index, a 0-to-1 scale that identifies how toxic a TKI is to heart cells (with 0 being the most toxic). They then used the index to rank the 21 TKIs. The control treatment scored a 1, while a few TKIs that are labeled by the FDA with boxed warnings for severe heart toxicity scored close to 0.

Safety indices like this one can be very useful during drug discovery, said Dr. Davis, and the applicability of the index developed by Dr. Wu and his colleagues will become clear when they evaluate its performance with more compounds.

And for the safety index to be applicable to more patients, the panel of cells used to develop it would need to be gathered from a sufficiently representative population of people reflecting different ages, races/ethnicities, health statuses, and other characteristics, said Lori Minasian, M.D., deputy director of NCIs Division of Cancer Prevention, who was not involved in either study.

For example, the study did not include cells derived from patients with [pre-existing] cardiac disease, said Dr. Davis.

A Personalized Approach

In addition to their potential application during drug development, Dr. Wu believes that stem cell-derived heart cells could potentially be used to predict toxicity risk for individual patients. He and his colleagues explored this possibility in their Nature Medicine study.

Doxorubicin, used on its own or in combination with other drugs, is an effective treatment for breast cancer and several other types of cancer. Like TKIs, however, it is known to cause heart toxicities, such as arrhythmias and heart failure, in a small proportion of patients. But there has been no way to predict which patients will experience these side effects.

The researchers developed stem cell-derived heart cells from eight women with breast cancer who had been treated with doxorubicinhalf of whom experienced cardiotoxicity from the treatment and half who did not.

In several different lab tests, the heart cells from women who had experienced cardiotoxicity were more sensitive to doxorubicin than those from women who had not. More specifically, in heart cells from women who had experienced cardiotoxicity, doxorubicin treatment caused more severe irregularities in cell contractility, and even low concentrations of the drug killed the cells.

An Improved Model

While the stem cell-derived heart cell model may be an improvement over the current [drug testing] system, its not perfect, said Dr. Minasian. For example, the model does not capture contributions of other organs and cells to the toxic effects of a drug, she explained. The drug may be broken down in the liver, for instance, and side products (called metabolites) may also cause toxic effects.

In addition, the lab-grown stem cell-derived version of someones heart cells are not going to be exactly the same as the cells found in that persons heart, Dr. Wu noted. Nevertheless, they reflect the same genetics and they are pretty good at predicting drug response, he said.

Looking forward, Dr. Minasian said, figuring out how to best use this approach is going to take more work, but being able to better predict human response [to cancer drugs] is important.

The research teams next steps include conducting prospective studies to determine whether they can use a patients stem cell-derived heart cells to potentially predict if that person will develop heart toxicity before they actually receive cancer treatment.

Cell Therapy Manufacturing Market (2017-2027): Near-Term Demand Driven by Clincial Candidates – Research and … – PR Newswire (press release)

Posted: March 24, 2017 at 3:42 pm

The Cell Therapy Manufacturing Market, 2017-2027 report provides an extensive study of the rapidly growing market of cell therapy manufacturing and focuses both on contract manufacturers and cell therapy developers with in-house manufacturing facilities. These therapies are anticipated to emerge as viable alternatives to conventional treatment options.

The scope of this report primarily includes manufacturing of advanced therapy medicinal products (ATMPs) that involve the use of immune cells such as T-cells, Tregs, dendritic cells, tumor cells and NK cells, and stem cells such as adult stem cells, human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs).

Several players, including cell therapy developers, research institutes, contract manufacturing organizations, and government and non-profit organizations, are playing a critical role in the development and manufacturing of these cell therapies. In fact, a number of these players have made heavy investments to expand their existing capabilities and establish new facilities for cell therapy products in order to meet the increasing demand.

Additionally, stakeholders have received significant support from governments worldwide, in terms of funding and establishment of consortiums to accelerate the transition of these therapies from laboratories to clinics. It is important to highlight that companies that offer logistics and operational services have developed systems / tools for safer and quicker delivery of therapies from manufacturing sites to patients; this has been identified as one of the key challenges in the overall development process.

The near-term demand for manufacturing of cell-based therapies will primarily be driven by clinical candidates. In the longer term, the currently approved therapies and late-stage therapies (that are likely to get commercialized in future) will act as key drivers of the market. Our outlook is highly promising; we expect the market for cell therapy manufacturing to grow at an annualized growth rate of -42% over the course of next ten years and be worth over USD 4 billion in 2027.
