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.

Bisphenol A chemical may shorten reproductive lifespan in women: Research

A study posted today (Wednesday, August 25) at the online site of the journal Biology of Reproduction reports that exposure of pregnant female mice to the endocrine-disrupting chemical bisphenol A may produce adverse reproductive consequences on gene expression in fetal ovaries as early as 12 hours after the mother has first been exposed to the chemical.

Researchers identify molecular signals that impact male fertility: Research

Male infertility is a common medical problem, affecting millions of men in the United States annually. Its causes include an inability to make productive sperm. Now, using yeast as a model organism, researchers at the University of Pennsylvania School of Medicine are beginning to identify the molecular signals that could in part underlie that problem.

Bacterial pathogens require vitamin B6 biosynthesis enzymes for virulence: Study

Scientists have determined that Helicobacter pylori, the bacterium that causes peptic ulcers and some forms of stomach cancer, requires the vitamin B6 to establish and maintain chronic infection, according to research published this week in the online journal mBio-. This finding, along with the identification of the enzyme the microbe requires to utilize the vitamin, could lead to the development of an entirely new class of antibiotics.

Deficiencies in DNA loop formation can cause multiple diseases: Research

The genes that are responsible for maintaining each cell type form DNA loops that link control elements for these genes. This surprising genome structure is generated and reinforced by two essential protein complexes that bridge the loops and contribute to proper gene regulation.

Maternal stress contribute to an elevated risk for depression in offspring: Research

For more than a century, clinical investigators have focused on early life as a source of adult psychopathology. Although the hypothesized mechanisms have evolved, a central notion remains: early life is a period of unique sensitivity during which experience confers enduring effects.

Best practices for assessing toxicity during drug discovery process

Ingenuity® Systems, the leading provider of information solutions for life science researchers, today announced the release of the white paper, "Best Practices for Assessing Toxicity throughout the Drug Discovery Process: Toxicogenomics." The white paper is based on input from industry experts and shows how multidisciplinary toxicology teams in drug discovery can leverage toxicogenomics and IPA® for improved predictive toxicology and mechanistic toxicity analysis.

Study discovers multiple effects of SSRIs on cells

A new discovery about selective serotonin reuptake inhibitors (SSRIs) suggests that these drugs, which are used to treat mental health disorders like depression and anxiety, have multiple effects on our cells. In a research report published in the August 2010 issue of GENETICS, researchers used yeast cells to identify secondary drug targets or pathways affected by SSRIs. Such secondary pathways could help explain why different people taking the same drug may experience different effects, and could also lead to new types of drugs altogether.

Nanoparticle-based gene silencing system inhibits angiogenesis process in tumor growth

A protein associated with cancer progression when abundant inside of tumors also unexpectedly regulates the creation of new blood vessels that feed the tumor outside, a research team led by scientists at The University of Texas MD Anderson Cancer Center reports in the August edition of Cancer Cell.

Study finds abnormal expression of miRNAs can contribute to human diseases

Researchers at Tufts University School of Medicine and Tufts Medical Center have identified an RNA sequence that promotes increased numbers of specific microRNAs (miRNAs), molecules that regulate cell growth, development, and stress response. The discovery helps researchers understand the links between miRNA expression and disease, including heart disease and cancer. The findings are published in the August 13 issue of Molecular Cell.

Researchers pace embryonic heart with laser

Scientists at Case Western Reserve University and Vanderbilt University found that pulsed light can pace contractions in an avian embryonic heart, with no apparent damage to the tissue. The work, "Optical pacing of the embryonic heart," will be published in the advanced online issue of Nature Photonics on Aug. 15, 2010.According to the scientists, this non-invasive device may prove an effective tool in understanding how environmental factors that alter an embryo's heart rate lead to congenital defects. It may also lead to investigations of cardiac electrophysiology at the cellular, tissue and organ levels, and possibly the development of a new generation of pacemakers.

MeCP2 regulatory protein determines vulnerability to cocaine addiction: Research

A regulatory protein best known for its role in a rare genetic brain disorder also may play a critical role in cocaine addiction, according to a recent study in rats, funded by the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health. The study was published today in the journal Nature Neuroscience.

A*STAR's Singapore Immunology Network, Institut M-rieux and bioM-rieux partner in TB research

An investment of S$3 million is being pumped into tuberculosis (TB) research by A*STAR's Singapore Immunology Network (SIgN), bioindustrial group Institut M-rieux and its in vitro diagnostics company bioM-rieux. The project, which involves setting up a joint laboratory in Biopolis, Singapore aims to investigate and identify novel biomarkers that could allow early identification of individuals at risk of TB disease development and disease reactivation. This could lead to better diagnosis and treatment for the highly contagious disease.

Venom-based nanoparticles improve gene therapy for fighting glioma

An ingredient in the venom of the "deathstalker" scorpion could help gene therapy become an effective treatment for brain cancer, scientists are reporting. The substance allows therapeutic genes - genes that treat disease - to reach more brain cancer cells than current approaches, according to the study in ACS Nano, a monthly journal.
