Acetylation News and Research

RSS

Acetylation (or in IUPAC nomenclature ethanoylation) describes a reaction that introduces an acetyl functional group into an organic compound. Deacetylation is the removal of the acetyl group.

Environment rich in sensory stimuli restores memory in mice with neurodegeneration

Mice whose brains had lost a large number of neurons due to neurodegeneration regained long-term memories and the ability to learn after their surroundings were enriched with toys and other sensory stimuli, according to new studies by Howard Hughes Medical Institute researchers.

Investigational cancer 17-AAG drug targets critical proteins

A drug under study to treat various cancers selectively kills cancer cells because of its affinity for a modified version of a critical heat shock protein they contain, researchers have found.

Gene silencing protein discovered

A team of researchers, including biologists at Washington University in St. Louis, has discovered the key role one protein plays in a major turn-off -in this case, the turning off of thousands of nearly identical genes in a hybrid plant.

Important new global mechanism for gene repression

Most of the time in most cells of the body, the great majority of genes are silenced, locked away within the compacted but orderly material that makes up chromosomes.

Study causes big shift in how we think about p53 gene

The cellular cascade of molecular signals that instructs cells with fatally damaged DNA to self-destruct pivots on the p53 tumor suppressor gene. If p53 is inactivated, as it is in over half of all human cancers, checks and balances on cell growth fail to operate, and body cells start to accumulate mutations, which ultimately may lead to cancer.

Researchers identify new areas of gene regulation

Researcher Kangling Zhang at the University of California, Riverside is part of a team that has discovered a new way that yeast governs genetic expression and repression, a finding that could be repeated in cells of other organisms.

Researchers shed new light on the development of cancers, particularly breast and prostate cancer

Researchers at Brown Medical School and Rhode Island Hospital have shed new light on the activation of a protein key to the development of cancers, particularly breast and prostate cancer, the most commonly diagnosed cancers in the United States.
