Epigenetic mark guides stem cells toward their destiny

Not all stem cells are completely blank slates. Some, known as adult stem cells, have already partially embraced their fates and are capable of becoming only cells of a particular type of tissue. So how do these tissue-specific stem cells restrict their fate?

MicroRNA undermines tumor suppression

Scientists at the Whitehead Institute for Biomedical Research and the National University of Singapore have discovered the first microRNA (miRNA) capable of directly tamping down the activity of the well known tumor-suppressor gene, p53, While p53 functions to prevent tumor formation, the p53 gene is thought to malfunction in more than 50% of cancerous tumors.

Alzheimer's mechanism suggests combination therapy needed

Researchers at the University of Illinois at Chicago College of Medicine have discovered a mode of action for mysterious but diagnostic protein snarls found in the brains of Alzheimer's patients that suggests a one-two punch of therapy may be needed to combat the neurodegenerative disease.

Discovery of new mechanism for the processing of endocannabinoids

New research funded by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, has identified a new mechanism for the processing of endocannabinoids, natural brain compounds similar to THC, the active ingredient in marijuana.

Suberoylanilide hydroxamic acid 'turns on' latent HIV

HAART (highly active anti-retroviral therapy) has emerged as an extremely effective HIV treatment that keeps virus levels almost undetectable; however, HAART can never truly eradicate the virus as some HIV always remains dormant in cells.

Diabetes cure in mice - answer is adult stem cells

More than five years ago, Dr. Lawrence C.B. Chan and colleagues in his Baylor College of Medicine laboratory cured mice with type 1 diabetes by using a gene to induce liver cells to make insulin.

Sirion Therapeutics sNDA for Durezol to treat uveitis accepted for FDA review

Sirion Therapeutics, Inc. announced today that its supplemental New Drug Application (sNDA) submitted to the U.S. Food and Drug Administration (FDA) seeking market approval of Durezol(TM) (difluprednate ophthalmic emulsion) 0.05% to treat endogenous anterior uveitis has been accepted for review.

Scientists 'watch' as individual alpha-synuclein proteins change shape

In an Early Edition publication of The Proceedings of the National Academy of Sciences (PNAS) this week, the researchers demonstrate the "alpha-synuclein dance" - the switching back and forth of the protein between a bent helix and an extended helix as the surface that it is binding to changes.

Identification of triggering mechanism by which breast and prostate cancer cells begin

Dr. Ercole Cavalieri and Dr. Eleanor Rogen of the University of Nebraska Medical Center, Eppley Institute for Research in Cancer, located in Omaha, Nebraska, have identified the triggering mechanism by which breast and prostate cancer cells begin. Preventium is a recently developed dietary supplement that promises to reduce people's risk for breast and prostate cancer.

Tiny probes help track down and attack cancer cells

A researcher has developed probes that can help pinpoint the location of tumors and might one day be able to directly attack cancer cells.

Discovery of master switch that might prevent cancer cells from metastasizing

Researchers at the University of Pennsylvania School of Medicine have identified a master switch that might prevent cancer cells from metastasizing from a primary tumor to other organs.

Researchers show how proteins find the right DNA sequences

Researchers at Uppsala University and Harvard University have collaboratively developed a new theoretical model to explain how proteins can rapidly find specific DNA sequences, even though there are many obstacles in the way on the chromosomes.

Immune cells play surprising role in cystic fibrosis lung damage

Immune cells once thought to be innocent bystanders in cystic fibrosis may hold the key to stopping patients' fatal lung disease.

Dendritic cells ensure immune tolerance

One of the most important tasks of the immune system is to identify what is foreign and what is self. If this distinction fails, then the body's own structures will be attacked, the result of which could be an autoimmune disease such as diabetes mellitus type 1 or multiple sclerosis. The only way to protect against these afflictions is to destroy all immune factors that turn against the body's own tissue - in other words: immune tolerance.
