Stem Cell Research Could Allow Women Post-Menopause Babies

Posted: Published on February 28th, 2012

A long-held belief about women and fertility is that each woman has a set amount of eggs in her lifetime and that when those eggs are depleted at menopause, so are her chances at having a biological child. However, research out of Massachusetts General Hospital is questioning that view. Using stem cells taken from human ovaries, scientists have produced early-stage eggs, which brings up all sorts of questions about possible new methods for treating infertility. Nicholas Wade, writing in The New York Times, adds, "The ability to isolate stem cells from which eggs could be cultivated would help not only with fertility but also with biologists' understanding of how drugs and nutrition affect the egg cells." Jonathan Tilly, the director of Mass General's Vincent Center for Reproductive Biology and leader of the new research, had reported in 2004 that ovarian stem cells in mice could create new eggs "similar to how stem cells in male testes produce sperm throughout a man's life." His new study attempted to prove this with humans. Researchers took healthy ovaries from patients having sex reassignment surgery, and injected stem cells from the ovaries into human ovarian tissue grafted under the skin of mice: "Within two weeks, early … Continue reading

Laboratories Essential to Success of Personalised Medicine, but Often Forgotten by Pharmaceutical Industry, According …

Posted: Published on February 28th, 2012

LONDON--(Marketwire -02/28/12)- Laboratories performing molecular or genetic diagnostic testing play a vital strategic role in the success of personalized medicine (PM), but are often the "forgotten" link, according to a new survey of 31 laboratories in five EU countries conducted by Labceutics, a division of Diaceutics, that provides value-enhancing laboratory networks and services for the PM industry. "We wanted to better understand the barriers faced by laboratory leaders as they seek to partner with pharmaceutical companies in the development of companion diagnostic tests for PM," said Maria Fe Paz, Managing Director of Labceutics. "Laboratories' interest in early participation has important implications for the success of pharmaceutical companies' PM businesses." Survey findings included: Laboratories as PM stakeholders have been largely forgotten by pharmaceutical companies, which wrongly assume that diagnostic partners have sufficiently engaged laboratories; Unlike the US, Europe has a fragmented laboratory market with strong country personalities, therefore centralized approaches may be too disruptive; A decentralised laboratory strategy in Europe will enable a "high touch" service among laboratory managers or pathologists and physicians; One-size-fits-all laboratory testing plans or "kit" approaches will encounter slow uptake in Europe; Successful introduction of PM therapeutics and companion diagnostics must include early preplanning with laboratories. "Labs … Continue reading

Posted: Published on February 28th, 2012

DEERFIELD, Ill.--(BUSINESS WIRE)-- Baxter International Inc. (NYSE:BAX - News) announced today that it has initiated a phase III pivotal clinical trial to evaluate the efficacy and safety of adult autologous (an individual’s own) CD34+ stem cells to increase exercise capacity in patients with chronic myocardial ischemia (CMI). Chronic myocardial ischemia (CMI) is one of the most severe forms of coronary artery disease, causing significant long-term damage to the heart muscle and disability to the patient. It is often diagnosed based on symptoms of severe, refractory angina, which is severe chest discomfort that does not respond to conventional medical management or surgical interventions. “The prospect of using a person’s own adult stem cells to restore and repair blood flow in CMI is a very exciting concept based on a biological regenerative approach,” said Norbert Riedel, Ph.D., Baxter’s chief science and innovation officer. “The goals of this phase III trial are aligned with Baxter’s overall mission to develop life-saving and life-sustaining therapies and it will help us determine if the therapy can make a meaningful difference for CMI patients.” The trial will enroll approximately 450 patients across 50 clinical sites in the United States, who will be randomized to one of three … Continue reading

Antisense oligonucleotides make sense in myotonic dystrophy

Posted: Published on February 28th, 2012

Public release date: 27-Feb-2012 [ | E-mail | Share ] Contact: Graciela Gutierrez ggutierr@bcm.edu 713-798-4710 Baylor College of Medicine HOUSTON (Feb. 27, 2012) ? Antisense oligonucleotides ? short segments of genetic material designed to target specific areas of a gene or chromosome ? that activated an enzyme to "chew up" toxic RNA (ribonucleic acid) could point the way to a treatment for a degenerative muscle disease called myotonic dystrophy, said researchers from Baylor College of Medicine and Isis Pharmaceuticals, Inc., in a report in the journal Proceedings of the National Academy of Sciences. "This is a proof-of-principle therapy that is very effective in cell culture and mice," said Dr. Thomas A. Cooper, professor of pathology and immunology and molecular and cellular biology at BCM and the report's corresponding author. "The treatment will have to be refined to deliver systemically in people with myotonic dystrophy." Myotonic dystrophy is the most common muscular disease in adults, affecting mainly the skeletal muscles, heart and central nervous system. It occurs because of a mutation that causes numerous repeats of three letters of the genetic code (CTG) in a gene called DMPK. RNA is made as a step in the cell's production of the protein … Continue reading

A Solution for Duchenne Muscular Dystrophy? — In Depth Doctor's Interview

Posted: Published on February 28th, 2012

Talk to us about where we are right now with personalized medicine. Dr. Hoffman: Personalized medicine there's different embodiments or sort of definitions to it. There's some in current use particularly with regards to drugs. So if you take some certain drugs certain people respond very poorly to. Based on how we metabolize them or don't metabolize them, how long the drug stays in the body. So there are now genetic tests that you can make sure you're giving the right amount of drug to the right patients. So that's a from of personalized medicine and that's been around for a couple of years. It's pretty tough it's only a couple of drugs that we really understand enough but it's already underway, particularly in chemotherapy, it's one of the key areas. Personalized medicine more broadly and in terms of drug development you can get more specific that a drug is designed specifically for a patient and even developed specifically for a patient. And that's sort of more a forward thinking definition of drug development is what we're working on here and is now heading in to clinical trials, or in clinical trials. So it is actually advancing quite quickly but … Continue reading

A Solution for Duchenne Muscular Dystrophy? – Research Summary

Posted: Published on February 28th, 2012

BACKGROUND: Duchenne muscular dystrophy (DMD) is an inherited disorder that involves rapidly worsening muscle weakness. This severe, debilitating and ultimately fatal disease is one of the most frequent genetic conditions affecting approximately 1 in 3500 male births worldwide. Affected boys are usually wheelchair-bound by their teenage years. By their late teens or twenties, the boys usually experience respiratory failure or cardiomyopathy often times resulting in death. SOURCE: (www.ncbi.nlm.nih.gov/pubmedhealth); (www.webmd.com); (www.plosone.org/)   CAUSES: DMD is genetic, but people without a known family history of the disease can get it as well. This fatal degenerative condition is caused by an absence or deficiency of dystrophin in striated muscle. Dystophin is a protein that helps keep muscle cells intact. It is also an integral structural component of skeletal and cardiac muscles and connects the contractile apparatus to the sarcolemma. SOURCE:  (www.plosone.org/) THINGS YOU DIDN'T KNOW: Males are more likely to inherit the disease than are women. The sons of females who are carriers of the disease (women with a defective gene but no symptoms themselves) each have a 50% chance of having the disease. The daughters each have a 50% chance of being carriers. SOURCE: (www.ncbi.nlm.nih.gov/pubmedhealth) DETECTIONS: With DMD, boys begin showing signs of … Continue reading

Prognostic factors for time to treatment failure and time to 12 months of remission for patients with focal epilepsy …

Posted: Published on February 28th, 2012

Background Epilepsy is a heterogeneous disorder, with outcomes ranging from immediate remission after taking a first antiepileptic drug to frequent unremitting seizures with multiple treatment failures. Few prognostic models enable prediction of outcome; we therefore aimed to use data from the SANAD study to predict outcome overall and for patients receiving specific treatments. Methods The SANAD study was a randomised controlled trial in which standard antiepileptic drugs were compared with new treatments. Arm A included patients for whom carbamazepine was considered the first-line treatment, most of whom were newly diagnosed with focal epilepsy. Patients were randomly assigned to receive carbamazepine, gabapentin, lamotrigine, oxcarbazepine, or topiramate. Outcomes were time to treatment failure overall, because of inadequate seizure control, and because of adverse events, and time to 12 months of remission from seizures. In this post-hoc study we used regression multivariable modelling to investigate how clinical factors affect the probability of treatment failure and the probability of achieving 12 months of remission. Findings For time to treatment failure, we identified several significant risk factors: sex (male vs female, hazard ratio [HR] 0·86, 95% CI 0·75—0·99), treatment history (taking non-SANAD antiepileptic drugs [other than those listed above] vs treatment naive, 1·27, 1·05—1·53), age … Continue reading
