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.

T-cell exhaustion

A new study of immune cells battling a chronic viral infection shows that the cells, called T cells, become exhausted by the fight in specific ways, undergoing profound changes that make them progressively less effective over time.

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.

Sex hormone signature indicates gender rather than just chromosomes

Help with assigning gender could one day be at hand for intersex individuals whose genital phenotypes and sex chromosomes don't match, thanks to the discovery of a stable sex hormone signature in our cells.

Connection between expression of clock genes and sleep

Genes responsible for our 24 hour body clock influence not only the timing of sleep, but also appear to be central to the actual restorative process of sleep, according to research published in the online open access journal BMC Neuroscience.

Research shows how stem cells decide to become either skeletal or smooth muscle

Researchers have discovered a key protein that controls how stem cells "choose" to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published in the Proceedings of the National Academy of Sciences (PNAS).

Researchers reveal repressor protein blocks neural stem cell development

A protein known to repress gene transcription at the molecular level in a variety of processes also blocks embryonic neural stem cells from differentiating into neurons, according to a study by University of California, San Diego and Howard Hughes Medical Institute (HHMI) researchers published online October 10 in Nature.

Genomic technologies to identify toxic chemicals should be developed

A new report from the National Research Council recommends that government agencies enhance their efforts to incorporate genomic data into risk assessments of chemicals and medicines, and calls for a concerted effort to fully develop these methods' potential to protect public health.

Fraunhofer pharmaceutical agent speeds drug development

It takes a great deal of time and money to develop a new drug. At Biotechnica in Hanover from October 9 to 11, the Fraunhofer Life Sciences Alliance will demonstrate how a pharmaceutical agent can make its way more quickly from the research laboratory to the pharmacy.

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.

PAZAR - virtual bazaar of gene regulation data

An international team has opened a virtual bazaar, called PAZAR, which allows biologists to share information about gene regulation through individually managed 'boutiques' (data collections).

Missouri-Columbia researchers look at mechanisms of cisplatin drug sensitivity

Resistance to chemotherapy treatments can be the worst news a cancer patient ever receives. A pair of researchers at the University of Missouri-Columbia is working steadfastly to learn why some tumors eventually build a tolerance to the common chemotherapy drug cisplatin, in hopes of identifying the particular genes that can be manipulated to make treatment as effective as possible.

Worm study sheds light on how the human body ages

Microscopic worms used for scientific research are living longer despite cellular defects, a discovery that is shedding light on how the human body ages and how doctors could one day limit or reverse genetic mutations that cause inherited diseases, according to a new University of Colorado at Boulder study.
