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.

Massive and consistent changes in inflammatory gene expression seen in trauma, burns

Serious traumatic injuries, including major burns, set off a "genomic storm" in human immune cells, altering around 80 percent of the cells' normal gene expression patterns. In a report to appear in the December Journal of Experimental Medicine, members of a nationwide research collaborative describe the initial results of their investigation into the immune system response to serious injury, findings which have overturned some longstanding assumptions.

First study to identify molecular mechanism that links inflammation to cancer epigenetics

Johns Hopkins Kimmel Cancer Center scientists report that sharp rises in levels of reactive oxygen molecules, and the inflammation that results, trigger biochemical changes that silence genes in a pattern often seen in cancer cells. The researchers confirmed this gene-silencing effect in mice that develop inflammation-induced colon cancer.

Research: lncRNA affects apoptosis and plays a role in RBC development

A long non-coding RNA (lncRNA) regulates programmed cell death during one of the final stages of red blood cell differentiation, according to Whitehead Institute researchers. This is the first time a lncRNA has been found to play a role in red blood cell development and the first time a lncRNA has been shown to affect programmed cell death.

Researchers sequence entire transcriptome of mouse neural retina

The population of Eric Morrow's seminar "Neurogenetics and Disease" comprises mainly undergraduates who were skipping down the halls of their elementary schools when the first drafts of human genome sequences were published. When Morrow, assistant professor of biology, recently asked the class how to find the mutation behind a disease, a hand shot up in the back of the class to signal the answer: "Sequence the patient's genome."

Relaxin improves poor blood flow and kidney function in a rat model of PKD

After a four-week course of the vasodilator hormone relaxin, kidney function and blood flow immediately improved in lab rats genetically altered to model polycystic kidney disease (PKD), a life-threatening genetic disorder, according to research presented on Dec. 6 at the American Society for Cell Biology Annual Meeting in Denver.

EMBL-EBI, BBSRC welcome UK funding announcement on behalf of life science community

The European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) and the Biotechnology and Biological Sciences Research Council (BBSRC) warmly welcome today's announcement from the UK Government of a £75 million commitment from the Department for Business, Innovation and Skills' Large Facilities Capital Fund (LFCF) for the ELIXIR research infrastructure.

Early stress of separation from biological parent impacts gene expression

Children who experience the stress of separation at birth from biological parents and are brought up in orphanages undergo biological consequences such as changes in their genome functioning, Yale School of Medicine researchers report in a new study.

Obesity maybe passed down from fathers to kids: Study

Australian researchers have found that the sperm of overweight fathers appears to carry a molecular signal that causes their offspring to inherit obesity. This may be more severe in female children and males they add.

Genetic variation predicts survival chances of ovarian cancer

Yale Cancer Center researchers have shown that a tiny genetic variation predicts chances of survival and response to treatment for patients with ovarian cancer.

Moffitt investigators to participate with 16 oral and 50 posters presentations at 53rd ASH meeting

When the American Society of Hematology convenes its 53rd Annual Meeting and Exposition on Dec. 10-13 in San Diego, Calif., researchers from Moffitt Cancer Center will break a new record for Moffitt participants with one plenary presentation, 16 oral presentations and more than 50 poster presentations on new research results in a variety of meeting programs that focus on blood cancer basic science and clinical applications, including bone marrow transplantation and clinical trials results.

New method reveals complete set of aberrant signaling pathways that give rise to cancers

One major obstacle in the fight against cancer is that anticancer drugs often affect normal cells in addition to tumor cells, resulting in significant side effects. Yet research into development of less harmful treatments geared toward the targeting of specific cancer-causing mechanisms is hampered by lack of knowledge of the molecular pathways that drive cancers in individual patients.

Specific electromagnetic fields can block cancer cell growth

New evidence by University of Alabama at Birmingham researchers that specific electromagnetic fields can safely block the proliferation of cancer cells and tumor growth may help refine a new, targeted therapy without any collateral damage.

Cisplatin anti-cancer drug binds pervasively to RNA

An anti-cancer drug used extensively in chemotherapy binds pervasively to RNA -- up to 20-fold more than it does to DNA, a surprise finding that suggests new targeting approaches might be useful, according to University of Oregon researchers.

Sex during adolescence can have negative effects on body and mood well into adulthood

A new study suggests that sex during adolescence can have lasting negative effects on the body and mood well into adulthood, most likely because the activity occurs when the nervous system is still developing.
