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.

Type of cellular stress called osmotic stress is critical to cell growth and the body’s immune response against infection

Researchers at the University of California, San Diego (UCSD) School of Medicine have determined that a particular type of cellular stress called osmotic stress is of critical importance to cell growth and the body’s immune response against infection.
