Gene Expression News and Research

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

New understanding on insulin resistance, action of diabetes drugs may lead to safer medication

A new understanding of insulin resistance and the action of diabetes drugs such as Avandia and Actos could pave the way for improved medications that are more selective and safer, say scientists from Dana-Farber Cancer Institute and The Scripps Research Institute.Our findings strongly suggest that good and bad effects of these drugs can be separated by designing second-generation drugs that focus on the newly uncovered mechanism, said Bruce Spiegelman, PhD, of Dana-Farber, senior author on a report appearing in the July 22 issue of Nature.

Researchers discover new gene regulation, DNA behavior of breast cancer cells

Cancer researchers have discovered a previously unknown type of gene regulation and DNA behavior in breast cancer cells that may lead to better insight about environmental exposure to estrogen-like compounds. A new study, published in the journal Genome Research by researchers at The Ohio State University Comprehensive Cancer Center-Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC-James), provides the first evidence that cells can regulate many genes at once by looping their DNA, contributing to cancer when it goes awry. In this study, the gene regulation was discovered in breast cancer cells as a response to the hormone estrogen and resulted in the silencing of 14 genes at one time.

AMPK may regulate epigenetic mechanism: Research

AMP-activated protein kinase, or AMPK, is a master regulator protein of metabolism that is conserved from yeast to humans. When a cell is low on fuel, AMPK shuts down processes that use energy and turns on processes that produce energy.Biologists have been studying how AMPK works for several decades and know that once it is activated, AMPK turns on a large number of genes by passing the "make more energy" message through numerous signaling cascades in the cell. What was not known, until now, was that AMPK also works via an epigenetic mechanism to slow down or stop cell growth.

Resveratrol concentration impacts cancer risk mitigation: Study

Agricultural Research Service (ARS) chemist Thomas Wang, who specializes in cancer prevention research, has reported evidence that for some dietary compounds, length of exposure over time may be key to whether or not ingestion leads to a beneficial, or detrimental, effect.Scientists do not know exactly why one person develops cancer and another does not. But they do know that certain nutrients might increase or decrease cancer risk. There are "layers" of factors involved in the development of cancer, and Wang is studying the layers involving peoples' diet complexity and gene expression.

Study compares denture stomatitis genes with whole transcriptome for salivary biomarker analysis

The goal of the study was to compare whole-transcriptome, mucosal gene expression in Candida albicans (a parasitic fungus that can infect the mouth) associated chronic denture stomatitis to that of healthy oral mucosa and perform proteomic analyses of potential salivary biomarkers. Denture stomatitis is a condition in which the mucosa underneath a denture becomes inflamed and sometimes painful.

Study reveals improved process to obtain, store RNA from lung tumor biopsies

Analyzing the genes expressed by cancer cells allows for a better understanding of that patient's specific disease and in turn, a more personalized approach to treatment. But obtaining the RNA from a tumor in the lungs in order to conduct the genetic analysis is a challenging prospect. Currently, lung cancer researchers are limited to using RNA extracted from early-stage tumors removed during surgery. The small quantities of tissue extracted during routine diagnostic biopsies have not been useful to researchers, due to their small size and the variety of ways they have been processed.

Exposure to cigarette smoke can alter gene expression, study finds

In the largest study of its kind, researchers at the Southwest Foundation for Biomedical Research have found that exposure to cigarette smoke can alter gene expression -- the process by which a gene's information is converted into the structures and functions of a cell. These alterations in response to smoking appear to have a wide-ranging negative influence on the immune system, and a strong involvement in processes related to cancer, cell death and metabolism.
