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.

Research into “insulating” brain cells could help to cure neurodegenerative diseases such as ALS

Johns Hopkins researchers say they have discovered that the central nervous system's oligodendroglia cells, long believed to simply insulate nerves as they "fire" signals, are unexpectedly also vital to the survival of neurons. Damage to these insulators appears to contribute to brain injury in neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease for the Yankee baseball great who died from the disease.

Genetic test helps avoid needless thyroid surgery

US researchers report that a gene-based test may help to identify patients who have cytologically indeterminate thyroid nodules that are benign.

Disabling Nf1 gene makes stem cells from the third ventricle proliferate rapidly

Scientists showed in mice that disabling a gene linked to a common pediatric tumor disorder, neurofibromatosis type 1 (NF1), made stem cells from one part of the brain proliferate rapidly. But the same genetic deficit had no effect on stem cells from another brain region.

MammaPrint more cost-effective and clinically-useful test than Oncotype DX

New research from University of the Sciences' Mayes College of Healthcare Business and Policy suggests that MammaPrint - a gene expression profiling (GEP) test used to identify whether women with early-stage breast cancer would benefit from chemotherapy - is the more cost-effective and clinically-useful test than the most frequently used GEP in practice in the United States today.

Human immune response: TCD scientists make breakthrough which could lead to new drug therapies

A team of researchers at Trinity College Dublin’s School of Medicine has gained new insights into a protein in the human immune system that plays a key role in the protective response to infection and inflammation. The research findings have just been published in the internationally renowned peer-reviewed Journal of Biological Chemistry.

Novel gene therapy approach may treat dysferlinopathies

The challenge of treating patients with genetic disorders in which a single mutated gene is simply too large to be replaced using traditional gene therapy techniques may soon be a thing of the past. A Nationwide Children's Hospital study describes a new gene therapy approach capable of delivering full-length versions of large genes and improving skeletal muscle function. The strategy may hold new hope for treating dysferlinopathies and other muscular dystrophies.

PHF21A gene plays a big role in Potocki-Shaffer syndrome

A gene whose mutation results in malformed faces and skulls as well as mental retardation has been found by scientists.

Epigenetic changes due to methylation play a key role in altering genes in RA

It's not just our DNA that makes us susceptible to disease and influences its impact and outcome. Scientists are beginning to realize more and more that important changes in genes that are unrelated to changes in the DNA sequence itself - a field of study known as epigenetics - are equally influential.

Important insight into association between childhood maltreatment and suicide

Exposure to childhood maltreatment increases the risk for most psychiatric disorders as well as many negative consequences of these conditions. This new study, by Dr. Gustavo Turecki and colleagues at McGill University, Canada, provides important insight into one of the most extreme outcomes, suicide.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

Safer alternative to experimental gene therapy against HIV infection

Scientists at The Scripps Research Institute have discovered a surprisingly simple and safe method to disrupt specific genes within cells. The scientists highlighted the medical potential of the new technique by demonstrating its use as a safer alternative to an experimental gene therapy against HIV infection.

New treatment target against metastatic pancreatic cancer

Detailed analysis of genes expressed in circulating tumor cells (CTCs) -- cells that break off from solid tumors and travel through the bloodstream -- has identified a potential treatment target in metastatic pancreatic cancer.

New platform for analysis of next generation sequencing data developed by Compugen

Compugen Ltd. (NASDAQ: CGEN) announced today the development of "NexGen," a new platform designed to significantly enhance Compugen’s overall infrastructure for predictive drug and drug target discovery. NexGen is designed to analyze Next Generation Sequencing data which is now beginning to be generated worldwide through RNA-Seq methodology.

FOXO1 gene may play an important role in pathological mechanisms of Parkinson's

A recent study led by researchers at Boston University School of Medicine (BUSM) revealed that the FOXO1 gene may play an important role in the pathological mechanisms of Parkinson's disease.

Prenatal exposure to PCBs impacts reproductive function in offspring

Prenatal exposure to the environmental contaminants polychlorinated biphenyls, or PCBs, causes long-term changes to the developing brain that have adverse effects on reproductive function later in life, a new study finds. Results will be presented Saturday at The Endocrine Society's 94th Annual Meeting in Houston.

Obese children show greater exposure to phthalates

Obese children show greater exposure than nonobese children to a phthalate, a chemical used to soften plastics in some children's toys and many household products, according to a new study, which found that the obesity risk increases according to the level of the chemical found in the bloodstream.

Prenatal exposure to BPA appears to program uterine estrogen responsiveness in adulthood

Prenatal exposure to bisphenol A, or BPA, a chemical found in many common plastic household items, can cause numerous genes in the uterus to respond differently to estrogen in adulthood, according to a study using a mouse model. The results will be presented Tuesday at The Endocrine Society's 94th Annual Meeting in Houston.

Researchers discover how GLP-2 receptor suppresses hunger and food intake

Researchers have discovered how a hormone in the gut slows the rate at which the stomach empties and thus suppresses hunger and food intake. Results of the animal study will be presented Monday at The Endocrine Society's 94th Annual Meeting in Houston.
