Discovery of gene related to p53 called Bnip3L that can also cause cell death

Researchers have known for a decade that the p53 tumor suppressor gene is important for killing cells as they proliferate under low-oxygen conditions inside tumors.

Protein in cardiac muscle cells may play a crucial role in heart failure prevention

Scientists at the University of North Carolina at Chapel Hill School of Medicine have shown that a protein in cardiac muscle cells may play a crucial role in heart failure prevention.

First LED device to receive approval for a medical claim associated with cosmetic improvement of aging and sun-damaged skin

Light BioScience announced today that the U.S. Food and Drug Administration (FDA) cleared GentleWaves Light Emitting Diode (LED) Photomodulation System for the non-invasive treatment of periorbital (eye area) wrinkles and rhytids.

Stem cells from umbilical cord blood effectively treated heart attacks

When injected into rats' hearts soon after a heart attack, stem cells taken from human umbilical cord blood (HUCB) greatly reduced the size of heart damage and restored pumping function to near normal. This improvement occurred without the need for drugs to prevent the rats' immune system from rejecting the human cells.

Stem cells could reveal secrets of illness in later life

Mums to be have known for some time that what they eat when pregnant affects their unborn child but now scientists believe that the diet of our mothers during pregnancy may even affect our predisposition to illnesses such as heart disease, diabetes and high blood pressure in late life.

New protein discovered holds promise for use in medicine and nanoscience

Researchers at the Hebrew University of Jerusalem have succeeded in discovering and isolating a new protein from the poplar tree with special structural and qualitative characteristics that could have consequences for development of future nanocapsules for drug delivery to cancer cells.

New technique could lead to more effective therapies for AIDS

When researchers came up with the powerful cocktail of anti-HIV drugs known as highly active antiretroviral therapy (HAART), they hoped they had found a way to finally rid the body of the virus. But they were wrong.

Novel approach to bioengineer artificial skin for burn victims

Each year more than 45,000 Americans suffer burns serious enough to require a hospital stay, according to the American Burn Association. While the traditional therapy of using skin grafts to cover burn sites has improved, a number of problems including scarring, infection and poor adhesion remain.

Technology that could double the effectiveness of cancer drugs

To identify the best treatment for recurrent ovarian cancer, researchers at Yale School of Medicine are studying a technology called the Yale apoptosis assay in combination with another technology called the ChemoFX assay, which could double the response rate to existing drugs.

Signaling molecule involved in osteoarthritis identified

Using naturally-occurring mutant mice with a defective collagen gene, scientists at Harvard have identified a signaling molecule involved in one of the most common causes of disability among the elderly in the United States, osteoarthritis.

Exposure to the chemical BPA (Bisphenol A) stimulates prostate cancer cell growth

An estrogen-like chemical commonly used to synthesize plastic food containers has been shown to encourage the growth of a specific category of prostate cancer cell, potentially affecting the treatment efficacy for a subset of prostate cancers.

Eli Lilly aware in the 1980s that fluoxetine had troubling side effects

The BMJ has turned over confidential drug company documents that went missing from a 10 year old murder case to the US Food and Drug Administration (FDA) for review.

Scientists have identified genes that promote the growth and recurrence of skin cancer

Dr. Andrzej Dlugosz and colleagues at the University of Michigan and the National Cancer Institute have examined the functions of the Hedgehog (Hh) signaling pathway in basal cell carcinoma, the most common form of cancer, and have uncovered a subset of tumor cells that are resistant to inhibition of the Hh pathway.

Ubiquitination protects against improper Notch signaling

The Notch pathway is an important molecular signaling mechanism whose existence has been known, or at least hinted at, for nearly a century since the identification of a mutant strain of Drosophila fruit flies with "notched" wings in Thomas Hunt Morgan's lab in 1910.

New findings clarify the role of NOD2, a key molecular player in Crohn's Disease

This week, researchers report new findings that clarify the role of NOD2, a key molecular player in Crohn's Disease, in the cellular signaling pathways that control inflammatory responses. NOD2's clinical relevance is clear from the fact that it is encoded by a Crohn's Disease susceptibility gene.

Evolution has been working very hard to produce us humans

The genes that regulate brain development and function evolved much more rapidly in humans than in nonhuman primates and other mammals because of natural selection processes unique to the human lineage. Researchers reported their findings in the cover article of the Dec. 29, 2004, issue of the journal Cell.

Significant advance in understanding the human genome

An Oregon Health & Science University-led development of a technique for identifying control elements that drive the expression of genes in brain cells could unleash the disease-fighting potential of the much-hailed human genome.

AIDS breakthrough - vaccine strengthens the body’s immune system againts HIV

A Hadassah University Medical Center research team has developed a vaccine that significantly strengthens the body’s immune system against the autoimmune sequela of HIV infection, a breakthrough that could dramatically make an impact in the treatment of AIDS patients.

New technique for tracking gene regulators

Finding out where gene-regulator proteins bind to DNA and identifying the genes they regulate just got a step easier thanks to a new technique developed by scientists at the U.S. Department of Energy’s Brookhaven National Laboratory.

Paclitaxel may benefit Alzheimer's and Parkinson's movement disorders

Angiotech Pharmaceuticals have announced that a preclinical study published in today's early edition of the Proceedings of the National Academy of Sciences highlights the positive effects of Paxceed on movement disorders commonly seen in diseases known as taupathies, such as Alzheimer's and Parkinson's.
