New link between polyamine regulation and ESC biology

A*STAR scientists have for the first time, identified that precise regulation of polyamine levels is critical for embryonic stem cell (ESC) self-renewal - the ability of ESCs to divide indefinitely - and directed differentiation.

Report highlights benefits of Nuvilex's cell encapsulation technology for diabetes

Nuvilex, Inc., an emerging biotechnology provider of cell and gene therapy solutions, today provided additional details based on the Goldman Small Cap Research report issued February 29, 2012, that highlighted the company's cell encapsulation technology and its benefits for treating chronic diseases such as diabetes.

SuperFAK protein decreases damage from heart attack by 50%

Researchers from the University of North Carolina at Chapel Hill reduced damage from a heart attack by 50 percent by enhancing a protective protein found in mice and humans.

Study uncovers how FoxO1 protein contributes to heart disease in patients with diabetes

UT Southwestern Medical Center cardiologists have uncovered how a specific protein's previously unsuspected role contributes to the deterioration of heart muscle in patients with diabetes. Investigators in the mouse study also have found a way to reverse the damage caused by this protein.

Alternative subunits generate different functional subtypes of RNA polymerases

Indiana University biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case protein subunits -- used to assemble those machines.

p14 ARF protein also regulates tumor-induced angiogenesis

Researchers at Winship Cancer Institute of Emory University have identified a new function for a gene that normally prevents the development of cancer.

DRI scientists create novel oxygen-generating material

Scientists at the Diabetes Research Institute have developed a revolutionary technique to provide critical oxygen for maintaining the survival of insulin-producing cells. This is the first time that scientists have been able to successfully deliver oxygen locally to beta cells using a biomaterial.

Metastatic melanoma patients with specific genetic mutation benefit from vemurafenib

A report published this week in the New England Journal of Medicine shows that the 50 percent of metastatic melanoma patients with a specific genetic mutation benefit from the drug Vemurafenib - increasing median survival from about 6 months to 15.9 months. In patients who responded, the drug stopped cancer progression for a median 6.7 months.

Flat worms may hold key to immortality

Experts from Nottingham University created a colony of more than 20,000 flatworms from one original by chopping it into pieces and observing each section grow into a new complete worm. They believe that it could help scientists develop new methods to allow humans to stay younger for longer.

Similar mechanisms drive changes in puberty

It's one of life's special moments: a child finds a fat caterpillar, puts it in a jar with a twig and a few leaves, and awakens one day to find the caterpillar has disappeared and an elegant but apparently lifeless case now hangs from the twig.

CD4 T cells can directly kill HIV-infected cells

A subpopulation of the immune cells targeted by HIV may play an important role in controlling viral loads after initial infection, potentially helping to determine how quickly infection will progress. In the February 29 issue of Science Translational Medicine, a team of researchers from the Ragon Institute of Massachusetts General Hospital (MGH), MIT and Harvard describe finding a population of HIV-specific CD4 T cells - cells traditionally thought to direct and support activities of other immune cells - that can directly kill HIV-infected cells.

FoxO protein plays a significant role in regulation of skeletal muscle mass

If you want big muscles without working out, there's hope. In the March 2012 print issue of the FASEB Journal, scientists from the University of Florida report that a family of protein transcription factors, called "Forkhead (Fox0)" plays a significant role in the regulation of skeletal muscle mass.

Loss of STAT1 transcription factor causes breast cancer development

Breast cancer represents about a fifth of all cancers diagnosed in women. The reasons for the rapid progression of the disease remain relatively poorly understood but recent work in the group of Veronika Sexl at the University of Veterinary Medicine, Vienna has pointed the finger strongly at loss or inactivation of the transcription factor STAT1.

TWRI team develops new drug against damaging effects of stroke

Scientists at the Toronto Western Research Institute (TWRI), Krembil Neuroscience Center, have developed a drug that protects the brain against the damaging effects of a stroke in a lab setting. This drug has been in development for a few years.

New system improves chances of pregnancy during IVF

A novel system for processing embryos during IVF treatment has been shown to significantly improve the chances of pregnancy - by more than a quarter.

Study examines mRNA transcripts in the sperm of fruitflies and humans

It had long been assumed that the human sperm cell's mission in life ended once it had transferred its freight of parental DNA to the egg. More recently however, other components of sperm have been implicated in fertilization, and perhaps even in subsequent embryonic development.

NKT cells may reduce monocytes accumulation, prevent lung injury in severe flu

While some scientists report engineering a super virulent strain of the H5N1 influenza virus, which could potentially wipe out a significant percentage of the human population, another group of researchers from the United Kingdom now reports a discovery that may one day help mitigate the deadly effects of all flu strains.

ACTB and ACTG1 actin genes cause Baraitser-Winter syndrome

Scientists from Seattle Children's Research Institute and the University of Washington, in collaboration with the Genomic Disorders Group Nijmegen in the Netherlands, have identified two new genes that cause Baraitser-Winter syndrome, a rare brain malformation that is characterized by droopy eyelids and intellectual disabilities.

HDAC2 enzyme could be a potential target for new Alzheimer's drugs

MIT neuroscientists have shown that an enzyme overproduced in the brains of Alzheimer's patients creates a blockade that shuts off genes necessary to form new memories. Furthermore, by inhibiting that enzyme in mice, the researchers were able to reverse Alzheimer's symptoms.

HPV and smear tests offer more effective approach for cervical screening

Testing for the human papillomavirus (HPV) - a virus most women will encounter at some point in their lives - followed by a smear test if they are HPV positive, provides the most effective approach for cervical screening, new research shows today.
