Molecular Biology News and Research

RSS

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Scientists identify how cell architecture changes during formation of gametes

Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell - and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process.

Researchers discover how protein ARTD1's DNA recruitment is regulated during inflammation

During inflammation, controlled gene expression is necessary in order to allow the organism to mount an effective defense response. For this process, the protein ARTD1 is removed from the DNA.

Cancer genomes in a common database and computation of disease drivers

The emerging field of "personalized" or "precision" medicine holds great promise in the fight against cancer. If scientists can identify the genetic changes that drive each patient's cancer cells, they can use that information to develop targeted treatments. But achieving this goal will require massive amounts of genomic and clinical data and a sophisticated infrastructure to manage and analyze the data.

Vitamin D strengthens innate immunity against viral infections

Vitamin D may be known as the sunshine vitamin, but a new research report appearing in the Journal of Leukocyte Biology shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases.

UAB researcher wins HudsonAlpha Prize for work on sickle cell and related blood disorders

Tim Townes, Ph.D., University of Alabama at Birmingham, was awarded the HudsonAlpha Prize for his work on sickle cell and related blood disorders. The $20,000 monetary award acknowledges exceptional talent, dedication and discovery by Alabama's best and brightest researchers.

Researchers define structure of key part of human obesity receptor

Medical researchers at the University of Sheffield have defined the structure of a key part of the human obesity receptor- an essential factor in the regulation of body fat- which could help provide new treatments for the complications of obesity and anorexia.

Heart can regulate energy balance throughout the body

UT Southwestern Medical Center researchers have demonstrated for the first time that the heart can regulate energy balance throughout the body, a finding that may point to more effective treatments for obesity, diabetes, and heart disease.

AAA to gather for anatomy meeting in conjunction with Experimental Biology 2012

The American Association of Anatomists will gather this week for its annual meeting in conjunction with the Experimental Biology 2012 conference, which will draw more than 14,000 scientists from industry, government and academia. Below are some programming highlights for the anatomy meeting. All presentations will be made at the San Diego Convention Center.

Fragile-X gene linked with disrupting de novo mutations in children with autism

A team led by scientists at Cold Spring Harbor Laboratory (CSHL) publishes research today indicating a striking association between genes found disrupted in children with autism and genes that are targets of FMRP, the protein generated by the gene FMR1, whose dysfunction causes Fragile-X syndrome.

Study shows how PCBs could add to autism risk

New research from UC Davis and Washington State University shows that PCBs, or polychlorinated biphenyls, launch a cellular chain of events that leads to an overabundance of dendrites - the filament-like projections that conduct electrochemical signals between neurons - and disrupts normal patterns of neuronal connections in the brain.

Louisiana Tech professor, students present at 2012 Experimental Biology meeting

Several graduate and Ph.D. students at Louisiana Tech University, and Dr. David Mills, professor of biological sciences and faculty in Tech's Center for Biomedical Engineering and Rehabilitation Science, are participating in poster and platform presentations at the 2012 Experimental Biology meeting, this week in San Diego, California.

Physical activity reduces oxidative stress in people with SCT

Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.

Custom-made mouthpieces can decrease levels of serum cortisol following exercise

Mouthguards are used by almost everyone participating in sports. These devices, typically purchased over-the-counter and used on the upper teeth, are designed to protect against broken teeth and an injured tongue. Recently, researchers in South Carolina found that a customized device which rests on the lower jaw can decrease levels of serum cortisol following exercise.

Gladstone researcher wins 2012 Alumni Achievement Award from WUSTL

Warner C. Greene, MD, PhD-who directs virology and immunology research at the Gladstone Institutes-has won the 2012 Alumni Achievement Award from the Washington University School of Medicine in St. Louis.

P-bodies have a much broader role in controlling the activities of the cell than previously thought

Cells can reuse the chemical messengers that carry genetic information to the machinery that makes proteins. Sometimes cells shuttle the messengers to storage and later reactivate them to make proteins, according to new research.

Self-degradation response to antidepressant Zoloft observed in yeast cells

Princeton University researchers have observed a self-degradation response to the antidepressant Zoloft in yeast cells that could help provide new answers to lingering questions among scientists about how antidepressants work, as well as support the idea that depression is not solely linked to the neurotransmitter serotonin.

Omega-3 supplements do not improve diastolic function in older adults

Over the past three decades, researchers have firmly established that the omega-3 fatty acids in fish oil, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have healthy effects on the heart. Omega-3 fatty acids seem to help both in preventing cardiovascular disease as well as in preventing future heart attacks, strokes, and other adverse events in people who have established cardiovascular disease.

Expression of specific GPCRs appears to play a role in prognosis of CLL

Researchers at the University of California-San Diego School of Medicine have shown that G protein-coupled receptor expression may predict the prognosis of patients with chronic lymphocytic leukemia. Their findings may identify new ways to treat such patients.

Oregano ingredient could treat prostate cancer

Oregano, the common pizza and pasta seasoning herb, has long been known to possess a variety of beneficial health effects, but a new study by researchers at Long Island University (LIU) indicates that an ingredient of this spice could potentially be used to treat prostate cancer, the second leading cause of cancer death in American men.
