Researchers stimulate the body to repair tissue damaged by peripheral arterial obstructive disease

Duke University Medical Center researchers have shown that they can stimulate the body to produce its own naturally occurring growth factors to promote blood vessel growth into tissue damaged by peripheral arterial obstructive disease (PAOD).

Researchers suggest how to generate B cells from stem cells

Before stem cells, of whatever origin, can be used to treat patients, scientists will need to learn how to coax them to develop into the desired cell types, a major challenge.

First use of technology called ubiquitin-mediated fluorescence complementation to study a cell-signaling mechanism called ubiquitination

Researchers at the University of Michigan Medical School and Howard Hughes Medical Institute have found a way to see proteins in cells that have been tagged by a molecular “sticky note” called ubiquitin.

Discovery of key molecular step which allows cancer cells to move to different parts of the body

Researchers at The University of Texas M. D. Anderson Cancer Center have figured out a key molecular step by which a cancer cell can unhook itself from the mesh weave of other cancer cells in a tumor, and move away to a different part of the body - the process, known as metastasis, that makes cancer so dangerous.

HER-2 cell surface receptors tun on genes associated with carcinogenesis

Researchers at The University of Texas M. D. Anderson Cancer Center now have evidence that receptors found on tumors that were believed to function only on the surface of cells can actually switch on genes inside a cell's nucleus, thus promoting cancer development in two distinct ways.

Liver cancer genes cluster into two subsets that correlate to survival

An analysis of the gene expression patterns of 91 unrelated liver tumors revealed two distinctive subclasses highly associated with patient survival, according to a new study published in the September 2004 issue of Hepatology.

New view of chromatin and gene activity

A genome - the DNA instructions for an organism - does not act alone. DNA is packaged with proteins into 'chromatin', which may be more or less tightly condensed. A popular proposal is that active genes are in 'open' chromatin (to allow access to them) and inactive genes are in tightly packed 'compact' chromatin.

Research crucial in determining what gene mutations might lead to congenital cardiovascular defects

According to the American Heart Association, congenital cardiovascular defects, such as congenital heart disease (CHD), are present in about one percent of live births and are the most common malformations in newborns.

Further evidence of a genetic link to schizophrenia

Mice with specific genetic mutations exhibit behavior similar to human psychosis, report UT Southwestern Medical Center at Dallas researchers, providing further support to the notion of a genetic link to schizophrenia.

New information about how HIV evades eradication from the body

Researchers at the National Cancer Institute, have discovered new information about how human immunodeficiency virus (HIV), the virus that causes acquired immune deficiency (AIDS), possibly evades eradication from the body.

Small molecules as artificial gene regulators

Scientists have been trying for some time to develop molecules that mimic natural regulators of gene expression.

Enzyme activation key to body clock

Feel like time is repeating itself and won’t move on? It could be your internal clock is backpedaling because your PKG-II is out of whack.

Discovery could revolutionise the way asthma is treated and managed, and possibly lead to an eventual cure

A major discovery by scientists at the Woolcock Institute of Medical Research could revolutionise the way asthma is treated and managed, and possibly lead to an eventual cure.

Lack of a gene called LBP-1a in the embryo prevents normal growth of blood vessels in the placenta

The lack of a gene called LBP-1a in the mouse embryo prevents normal growth of blood vessels in the placenta. This finding suggests that a similar defect in humans could play a role in fetal growth retardation, infant mortality and spontaneous abortion.

New gene-silencing technique

A new gene-silencing technique that takes place in the nucleus of human cells, has been demonstrated by researchers at the University of California, San Diego (UCSD) School of Medicine and the VA San Diego Healthcare System.

The p53 transcription factor plays a vital role in preventing cancer onset

Researchers at the Uppsala Branch of the Ludwig Institute for Cancer Research have discovered that the transcription factor Yin Yang 1 (YY1) is a novel regulator of the tumor suppressor p53, which is inactivated in at least half of all human cancers.

Latest findings on HIV pathogenesis at AIDS Conference in Bangkok

At the XVth International AIDS Conference in Bangkok, Thailand, Anthony S. Fauci, M.D., director of the National Institute of Allergy and Infectious Diseases and chief of the NIAID Laboratory of Immunoregulation (LIR), will present his laboratory’s latest findings on how aberrant immune activation underlies HIV pathogenesis.

Molecular mechanisms behind XsalF's anterior specifying activity

Embryologists have long been interested in working out the means by which this regionalization is achieved, and for years the dominant theory has involved a two-step mechanism in which neural tissues are first induced lengthwise down the entire body axis, followed by a transformation step where a second signal specifies the posterior identities of the neural tissue

The structure of AGT shows how one human protein reduces the potency of chemotherapy

The fine details of this x-ray structure may help scientists find ways to fight certain cancers, such as brain tumors, which express high levels of AGT making them resistant to chemotherapy.
