Eric Selker's lab reports progress on biochemical communications among proteins involved in gene silencingResearchers in a University of Oregon lab have shed more light on the mechanism that regulates DNA methylation, a fundamental biological process in which a methyl group is attached to DNA, the genetic material in cells of living organisms.DNA methylation is essential for normal growth and development in plants and animals. It has been implicated in long-term memory, and irregularities in...

The Stowers Institute's Workman Lab has discovered a novel histone demethylase protein complex characterized in work published today in Molecular Cell.The Histone H3 protein is an important component of chromatin, the packing material wrapping up chromosomal DNA and preventing unwanted transcription of the message encoded in the DNA. Histone H3 can be altered by adding (methylating) or removing (demethylating) methyl groups from the histone protein. When genes are transcribed, parts of...

An herb used in traditional medicine by many Middle Eastern countries may help in the fight against pancreatic cancer, one of the most difficult cancers to treat. Researchers at the Kimmel Cancer at Jefferson in Philadelphia have found that thymoquinone, an extract of nigella sativa seed oil, blocked pancreatic cancer cell growth and killed the cells by enhancing the process of programmed cell death.

Reshaping of the DNA scaffolding that supports and controls the expression of genes in the brain may play a major role in the alcohol withdrawal symptoms, particularly anxiety, that make it so difficult for alcoholics to stop using alcohol.
