New cancer gene UTX identified

Getting down to cancer basics — Cancer mutations in the heart of gene regulation. – Researchers have identified a new cancer gene – one that is common to many cancers and affects the most basic regulation of our genes.

New monkey model for HIV

A slightly altered HIV-1 strain can infect pig-tailed macaques in the first animal model for human immunodeficiency virus infection. – By altering just one gene in HIV-1, scientists have succeeded in infecting pig-tailed macaque monkeys with a human version of the virus that has until now been impossible to study directly in animals.

Pollution related asthma starts in womb

Research suggests pollution-related asthma may start in the womb – Children born in areas with increased traffic-related pollution may be at greater risk of developing asthma due to genetic changes acquired in the womb, according to new research from the University of Cincinnati (UC) and Columbia University Mailman School of Public Health.

A universal mechanism of aging is identified

New evidence may explain why it is that we lose not only our youthful looks, but also our youthful pattern of gene activity with age. – Researchers have discovered that DNA damage decreases a cell’s ability to regulate which genes are turned on and off in particular settings. This mechanism, which applies both to fungus and to us, might represent a universal culprit for aging.

Purple, high anthocyanin tomatoes offer protection against certain cancers

High anthocyanins content tomatoes, produced by European researchers, may be able to extend lifespan in cancer-prone mice; the finding by the FLORA European Project published in the journal Nature Biotechnology. – Scientists have expressed genes from snapdragon in tomatoes to grow purple tomatoes high in health-protecting anthocyanins.

Suppressing hunger hormone ghrelin as good as bariatric surgery

Chemical suppressing hunger hormone yields result as good as bariatric surgery to reduce obesity. – Johns Hopkins scientists report success in significantly suppressing levels of the “hunger hormone” ghrelin in pigs using a minimally invasive means of chemically vaporizing the main vessel carrying blood to the top section, or fundus, of the stomach.

Estrogen does not improve sun-damaged skin

Long-term sun exposure hinder the ability of topical estradiol to stimulate collagen production in aged human skin. – Treating the skin with estrogen can stimulate collagen production-which improves the appearance of the skin-in areas not typically exposed to the sun, according to new research from the University of Michigan Health System.

Chromosomal changes increase schizophrenia risk

Schizophrenia may be partly caused by the effects of unusual structural changes in genes. – People with schizophrenia (mental illness variously affecting behavior, thinking, and emotion) have an increased number of unusual chromosomal changes, particularly structural changes that have the potential to alter the function of the genes.

Contaminant identified in tainted Baxter’s heparin

MIT reseachers have explained how contaminated batches of the blood-thinner heparin were able to slip past traditional safety screens. – An international team of researchers led by Massachusetts institute of technology (MIT) has explained how contaminated batches of the blood-thinner heparin were able to slip past traditional safety screens and kill dozens of patients recently in the United States and Germany.
