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.

700 scientists to present new information on smell and taste at AChemS 32nd annual meeting

The Association for Chemoreception Sciences (AChemS), a US-based scientific organization, is holding its 32nd annual meeting. About 700 scientists are gathering to present new information on the role of smell and taste in disease, nutrition and social interactions in humans as well as animals. Smell and taste play essential roles in our daily lives. These chemical senses serve as important warning systems, alerting us to the presence of potentially harmful situations or substances, including gas leaks, smoke, and spoiled food.

Marker found in iPS cells correlates with levels of pluripotency: Researchers

Researchers in China are reporting that they have found a way to determine which somatic cells -- or differentiated body cells -- that have been reprogrammed into a primordial, embryonic-like state are the most viable for therapeutic applications.

Calorie restriction may help people to lead longer and healthier lives

Organisms from yeast to rodents to humans all benefit from cutting calories. In less complex organisms, restricting calories can double or even triple lifespan. It's not yet clear just how much longer calorie restriction might help humans live, but those who practice the strict diet hope to survive past 100 years old.

Sexual minorities more likely to experience posttraumatic stress disorder

A new study from researchers at the Harvard School of Public Health (HSPH) and Children's Hospital Boston has found that gay men, lesbians, bisexuals, and heterosexuals who have ever had a same-sex sex partner are one-and-a-half to two times as likely to experience violent events, especially in childhood, than the general population.

Albert Einstein College of Medicine of Yeshiva University receives funds to expand stem cell research capabilities

Albert Einstein College of Medicine of Yeshiva University has been awarded $10 million from the National Institutes of Health to expand its stem cell research capabilities. The funds will be used to create new laboratories in order to increase its already substantial base of stem cell investigators.

Study links cancer growth to sugar-based modification found naturally in the body

Researchers at Drexel University College of Medicine have discovered that a certain type of sugar found naturally in the body is elevated in breast cancer cells and is critical for cancer growth and movement. When researchers reduced and normalized the levels of this sugar, they were able to slow the growth of the cancer cells and block invasion. The findings, published in the March 1 issue of Oncogene, represent a potential new therapeutic target for treating aggressive forms of breast cancer.

Increase in circulating stem cells can be achieved through Stem-Kine: Study

A study published in the peer reviewed Journal of Translational Medicine demonstrated administration of Stem-Kine, a commercially available nutritional supplement, significantly elevated levels of two types of stem cells in circulation.

Study of changes in transcription factor binding can help understand evolution of gene regulation

As published today in Science, researchers from Cambridge, Glasgow and Greece have discovered a remarkable amount of plasticity in how transcription factors, the proteins that bind to DNA to control the activation of genes, maintain their function over large evolutionary distances.

Hormones leptin and insulin work together to affect regulation of blood sugar levels, female fertility

New findings by UT Southwestern Medical Center researchers suggest that the hormones leptin and insulin work together in specific neurons in the hypothalamus region of the brain to affect both the regulation of blood sugar levels in the body and, surprisingly, female fertility.

Aptium Oncology Myeloma Consortium launched

Aptium Oncology, Inc. today announced the launch of Aptium Oncology Myeloma Consortium (AMyC), a broad-based collaboration that brings together renowned investigators to work with pharmaceutical sponsors to advance clinical and translational research in myeloma and related cancers.

Researchers report major step forward in effort to understand and engineer protein structure

Researchers in Singapore are reporting this week that they have gleaned key insights into the architecture of a protein that controls iron levels in almost all organisms. Their study culminated in one of the first successful attempts to take apart a complex biological nanostructure and isolate the rules that govern its natural formation.

Accumulation of mutated protein may explain damaging cellular behavior in Huntington's disease

In a step towards a possible treatment for Huntington's disease, scientists at Albert Einstein College of Medicine of Yeshiva University have shown for the first time that the accumulation of a mutated protein may explain damaging cellular behavior in Huntington's disease. Their research is described in the April 11 online edition of Nature Neuroscience.

Ku protein employs unique mechanism for DNA repair: Researchers

Scientists have shown in multiple contexts that DNA damage over our lifetimes is a key mechanism behind the development of cancer and other age-related diseases. Not everyone gets these diseases, because the body has multiple mechanisms for repairing the damage caused to DNA by aging, the environment and other human behaviors - but the mechanisms behind certain kinds of DNA repair have not been well-understood.

Scientists discover and block pathway responsible for link between stress, anxiety and depression

Scientists at The University of Western Ontario have discovered the biological link between stress, anxiety and depression. By identifying the connecting mechanism in the brain, this high impact research led by Stephen Ferguson of Robarts Research Institute shows exactly how stress and anxiety could lead to depression.

Drugs that affect methylation state of genes could reverse autism's effects: The FASEB Journal

A new discovery raises hope that autism may be more easily diagnosed and that its effects may be more reversible than previously thought. In a new study appearing online in The FASEB Journal, scientists have identified a way to detect the disorder using blood and have discovered that drugs which affect the methylation state of genes could reverse autism's effects.
