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.

Childhood poverty, demographics associated with DNA methylation patterns

A University of British Columbia and Centre for Molecular Medicine and Therapeutics (CMMT) study has revealed that childhood poverty, stress as an adult, and demographics such as age, sex and ethnicity, all leave an imprint on a person's genes. And, that this imprint could play a role in our immune response.

New study decodes complete epigenome of chronic lymphocytic leukemia

Researchers of the University of Oviedo have contributed to decipher the first epigenomes of chronic lymphocytic leukemia.

Research may lead to new ways to identify women with breast cancer risks from low-dose radiation

Scientists from the U.S. Department of Energy's Lawrence Berkeley National Laboratory have identified tissue mechanisms that may influence a woman's susceptibility or resistance to breast cancer after exposure to low-dose ionizing radiation, such as the levels used in full-body CT scans and radiotherapy.

Genetic signatures for aggressive prostate cancer identified

Researchers have identified two genetic signatures for castration-resistant prostate cancer that may predict the severity of the disease.

Recurrent patterns of genomic imbalances determine evolution of invasive breast cancer

Ductal carcinoma in situ (DCIS) is considered a precursor lesion for invasive breast cancer if untreated, and is found in approximately 45% of patients with invasive ductal carcinoma (IDC). Patients with DCIS only (not accompanied by invasive disease) have a 5-year-survival of nearly 100%, compared to 89% for all stages of invasive breast cancer (24% for patients with distant metastasis).

Companionship can reduce nerve-related pain

Companionship has the potential to reduce pain linked to nerve damage, according to a new study.

NIH to accelerate development and application of single cell analysis across various fields

The National Institutes of Health plans to invest more than $90 million over five years, contingent upon the availability of funds, to accelerate the development and application of single cell analysis across a variety of fields.

Enrollment complete in Idera's IMO-3100 Phase 2 trial for psoriasis

Idera Pharmaceuticals today announced that it had completed patient enrollment in its randomized, double-blind, placebo-controlled Phase 2 trial of IMO-3100 in patients with moderate-to-severe plaque psoriasis. IMO-3100 is an antagonist of specific Toll-like Receptors (TLRs) that the Company is developing for the treatment of psoriasis and other autoimmune diseases.

Variable methylation predictive of age, gender, stress, cancer and early-life socioeconomic status

A Simon Fraser University physicist has helped discover that understanding how a chemical mark on our DNA affects gene expression could be as useful to scientists as fingerprints are to police at a crime scene.

Researchers identify new genetic signature for sarcoidosis

Researchers at the University of Illinois Hospital & Health Sciences System have identified a genetic signature that distinguishes patients with complicated sarcoidosis, an inflammatory lung disease that can be fatal, from patients with a more benign form of the disease. The gene signature could become the basis for a simple blood test.

Tissue test detects oral cancer risk

A molecular diagnostic scoring system based on patients’ FOXM1-associated gene messenger RNA expression levels is able to quantitatively diagnose and stratify oral carcinoma and its aggressiveness, show UK and Norwegian study results.

TSRI scientists identify new gene variants closely associated with bipolar disorder

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have identified small variations in a number of genes that are closely linked to an increased risk of bipolar disorder, a mental illness that affects nearly six million Americans, according to the National Institute of Mental Health.

New screening method may lead to more efficient RNA drug development

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have developed a new method of screening more than three million combinations of interactions between RNA and small molecules to identify the best targets on RNA as well as the most promising potential drug compounds.

Study compares gene expression levels in two key hippocampal regions affected by Alzheimer's

Researchers from the Computational Intelligence Group based at the Universidad Politécnica de Madrid's Facultad de Informática have used machine learning and data mining techniques to compare gene expresssion levels in Alzheimer's disease (AD) patients in two key regions of the hippocampus: the dentate gyrus, where the disease appears to have little or no effect, and the entorhinal cortex, where Alzheimer's disease produces major neuronal damage.

Morphine inhibits BDNF protein, whereas cocaine enhances BDNF

Chronic morphine exposure has the opposite effect on the brain compared to cocaine in mice, providing new insight into the basis of opiate addiction, according to Mount Sinai School of Medicine researchers. They found that a protein called brain-derived neurotrophic factor (BDNF), which is increased in cocaine addiction, is inhibited in opioid addiction. The research is published in the October 5 issue of Science.

Researchers discover smallest and fastest-known RNA switches

A University of Michigan biophysical chemist and his colleagues have discovered the smallest and fastest-known molecular switches made of RNA, the chemical cousin of DNA. The researchers say these rare, fleeting structures are prime targets for the development of new antiviral and antibiotic drugs.

NFKB1 gene variant may reduce risk of lung cancer

A variant in a gene involved with inflammation and the immune response is linked with a decreased risk of lung cancer. That is the finding of an analysis published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The results add to the growing body of literature implicating these processes in the development of lung cancer.

New ways of how biological clock's neurons use electrical activity to keep behavioral rhythms in order

Biologists from New York University have uncovered new ways our biological clock's neurons use electrical activity to help keep behavioral rhythms in order. The findings, which appear in the journal Current Biology, also point to fresh directions for exploring sleep disorders and related afflictions.

BUSM leads genome-wide evaluation of genetic variants associated with Parkinson's disease

Boston University School of Medicine investigators have led the first genome-wide evaluation of genetic variants associated with Parkinson's disease (PD). The study, which is published online in PLOS ONE, points to the involvement of specific genes and alterations in their expression as influencing the risk for developing PD.
