HDAC inhibitors show potential as therapeutic agents in treating alcoholism

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.

REST protein protects embryonic stem cells' versatility and self-renewal

A protein known as REST blocks the expression of a microRNA that prevents embryonic stem cells from reproducing themselves and causes them to differentiate into specific cell types, scientists at The University of Texas M. D. Anderson Cancer Center report in the journal Nature.

Location location location, even for genes

Moving an active gene from the interior of the nucleus to its periphery can inactivate that gene report scientists from the University of Chicago Medical Center in an article to be published early online Feb.13, 2008, in the journal Nature.

Asf1, the protein that oversees DNA replication and packaging in the cell

At the Institut Curie, the CNRS team of Genevieve Almouzni has just discovered how the protein Asf1 ensures the correct (re)organization of duplicated DNA. During DNA replication, all the information in the mother cell must be transmitted to the daughter cells.

Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed

During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue.

Compound of milk thistle shows anti-cancer effects

Recently, scientists demonstrated the anti-cancer effects of silibinin, a major biologically active compound of milk thistle. Being widely used as a folk remedy for liver diseases, milk thistle is safe and well-tolerated, and it protects the liver from drug or alcohol-related injury.

piRNAs play an important role in controlling gene function

A study by researchers at the Yale Stem Cell Center for the first time demonstrates that piRNAs, a recently discovered class of tiny RNAs, play an important role in controlling gene function, it was reported this week in Nature.

Transgenics sped up

A new method of constructing artificial plant chromosomes from small rings of naturally occurring plant DNA can be used to transport multiple genes at once into embryonic plants where they are expressed, duplicated as plant cells divide, and passed on to the next generation -- a long-term goal for those interested in improving agricultural productivity.

Tolerance to inhalants may be caused by changes in gene expression

Changes in the expression of genes may be the reason why people who abuse inhalants, such as spray paint or glue, quickly develop a tolerance, biologists at The University of Texas at Austin have discovered.

Human embryonic stem cells remain embryonic because of epigenetic factors

A human embryonic stem cell is reined in - prevented from giving up its unique characteristics of self-renewal and pluripotency - by the presence of a protein modification that stifles any genes that would prematurely instruct the cell to develop into heart or other specialized tissue.

Gene-chip studies provide new leads in treating abnormal lung development in premature newborns

Some 20 to 40 percent of extremely premature infants suffer abnormal lung development leading to bronchopulmonary dysplasia, a chronic lung disease that can cause long-term breathing problems.
