Gene Expression News and Research

RSS

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.

Stony Brook University CFB establishes Biotechnology Commercialization Fund

Researchers uncover new details of unusual biological mechanism in brains of diverse species

Researchers at the University of California, San Diego School of Medicine have uncovered new details of an unusual biological mechanism in the brains of diverse species that not only helps regulate how their brains develop, but also how they function later in life. The discovery could lead to new biomarkers for specific neurological diseases in humans and, possibly, the development of drugs to cure them.

Pitt researchers develop mouse model of major depressive disorder

Researchers at the University of Pittsburgh School of Medicine have developed a mouse model of major depressive disorder (MDD) that is based on a rare genetic mutation that appears to cause MDD in the majority of people who inherit it.

MDC researchers comprehensively quantify gene expression for the first time

How do genes control us? This fundamental question of life still remains elusive despite decades of research. Genes are blueprints for proteins, but it is the proteins that actually carry out vital functions in the body for maintaining life. Diseases such as cancer are not only characterized by altered genes, but also by disturbed protein production.

Children exposed to maternal smoking in utero have increased DNA methylation in AXL gene

Children whose mothers or grandmothers smoked during pregnancy are at increased risk of asthma in childhood, but the underlying causes of this are not well understood. Now a new study indicates changes in a process called DNA methylation that occurs before birth may be a root cause.

A new gene expression analysis technique on a single molecule sequencer

A new gene expression technique adapted for single molecule sequencing has enabled researchers at the RIKEN Omics Science Center (OSC) to accurately and quantitatively measure gene expression levels using only 100 nanograms of total RNA. The technique, which pairs RIKEN's Cap Analysis of Gene Expression (CAGE) protocol with the Helicos(R) Genetic Analysis System developed by Helicos BioSciences Corporation, opens the door to the detailed analysis of gene expression networks and rare cell populations. In recent years, next-generation DNA sequencers have produced an increasingly detailed picture of how genes are expressed at the molecular level. The transcriptional output of these genes - the RNA copies produced from DNA - has revealed a richness of complexity in transcript structure and function, providing insights into the molecular-level properties of cancers and other diseases.

Researchers lay foundation for future lung cancer detection test

Scientists working with Professor Dr. Joachim L. Schultze have identified over 480 molecules whose concentration in the blood changes when a person develops lung cancer. These molecules are present in the blood cells either in increased or decreased quantities. "In lung cancer patients, typical patterns which can be detected with a measuring program thus emerge", explains Prof. Schultze.

Researchers uncover unexpected role of estrogen receptors in brain inflammation

Researchers have uncovered an unexpected role for estrogen receptors in the brain in keeping inflammation under control. The findings reported in the May 13 issue of the Cell Press journal Cell may have important implications for the treatment of multiple sclerosis (MS) and many other neurodegenerative diseases.

New computational model can analyze living cells, social networks

At first glance, a diagram of the complex network of genes that regulate cellular metabolism might seem hopelessly complex, and efforts to control such a system futile. However, an MIT researcher has come up with a new computational model that can analyze any type of complex network - biological, social or electronic - and reveal the critical points that can be used to control the entire system.
