Stowers Institute for Medical Research Changes in how DNA interacts with histones–the proteins that package DNA–regulate many fundamental cell activities from stem cells maturing into a specific body cell type or blood cells becoming leukemic. These interactions are governed by a biochemical tug of war between repressors and activators, which chemically modify histones signaling them to clamp down tighter on DNA or move aside and allow a gene to be expressed. In the November...

The study has been published in the prestigious journal Molecular Cell Researchers at the Hospital de Mar Research Institute (IMIM) have discovered that the protein LOXL2 has a function within the cell nucleus thus far unknown. They have also described a new chemical reaction of this protein on histone H3 that would be involved in gene silencing, one of which would be involved in the progression of breast, larynx, lung and skin tumours. Led by Dr Sandra Peiró and published...

Post-translational modifications of histones play an important role in regulating chromatin dynamics and function. One such modification, methylation, is involved in the regulation of the epigenetic program of a cell, determining chromatin structure, and regulating transcription. Methylation of histones occurs on both lysine and arginine residues, and until recently, was thought to be an irreversible process. The recent discovery of histone demethylases revealed that histone methylation is...

Findings may lead to new drug targets A subtle mutation affecting the epigenome "“ a set of dynamic factors that influence gene activity -- may lead to an inherited form of mental retardation that affects boys, find researchers at Children's Hospital Boston. The disorder, which also involves cleft lip or cleft palate, appears to hinge on an enzyme working in a biological pathway that may offer several potential drug targets. The study, published online July 11 in the journal Nature,...

A study from the University of North Carolina at Chapel Hill has identified a key player in a molecular process essential for DNA replication within cells. The new findings highlight a protein called FLASH, already shown to play a role in initiating apoptosis, or programmed cell death. Apoptosis is a normal biochemical response that occurs when a cell is damaged beyond repair after viral infection or accumulation of mutations that could lead to uncontrolled cellular proliferation, or cancer....

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...
