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.

High fat diet and exercise stimulate the breakdown of fats

Scientists report in the October issue of the Journal of Lipid Research that when either lean or obese individuals exercise after eating a high fat meal, their fats are broken down and oxidized in skeletal muscle, making them healthier.

Study looks at Atorvastatin and cholesterol

Scientists report in the October issue of the Journal of Lipid Research new details about how a drug used against heart disease helps to unclog blood vessels from an excess of cholesterol and fats.

Effects of modified alternate-day fasting

Researchers report in the October issue of the Journal of Lipid Research that fasting or eating half as much as usual every other day may shrink your fat cells and boost mechanisms that break down fats.

How can a medical center foster a culture of ethics in research?

An article published in the September issue of Academic Medicine, titled "Developing a Research Ethics Consultation Service to Foster Responsive and Responsible Clinical Research," argues for the importance of collaboration between researchers and ethicists and describes the establishment of a new Research Ethics Consultation Service at Weill Cornell Medical College.

N-cofilin molecule protects from neuronal disorders

Many neuronal disorders, including epilepsy, schizophrenia and lissencephaly – a form of mental retardation - result from abnormal migration of nerve cells during the development of the brain.

Zebrafish shed light on human mitochondrial diseases

Zebrafish can now be used to study COX deficiencies in humans, a discovery that gives scientists an unprecedented window to view the earliest stages of mitochondrial impairments that lead to potentially fatal metabolic disorders, according to researchers at the University of Oregon.

New technique detects how proteins undergo changes inside a cell

In the September issue of Molecular & Cellular Proteomics , scientists describe a new technique that can detect how proteins undergo changes inside a cell.

New understanding of tropical disease schistosomiasis

Researchers have provided new details about the inner workings of a parasitic worm that causes a tropical disease called schistosomiasis, which leads to itchy skin, fever, chills, muscle aches, and liver disease that, in some cases, can be fatal.

New insight into breast cancer development in high-risk women

Physicians who treat women with the breast cancer susceptibility gene BRCA1 often remove their patients' ovaries to eliminate the source of estrogen they believe fuels cancer growth.

Mutations in the insulin gene can cause permanent neonatal diabetes

Mutations in the insulin gene can cause permanent neonatal diabetes, an unusual form of diabetes that affects very young children and results in lifelong dependence on insulin injections, report researchers from the University of Chicago and Peninsula University (Exeter, UK) in Sept. 18, 2007, issue of the Proceedings of the National Academy of Sciences, published early online.

Discovery of tendon cells that self-renew

Athletes know that damage to a tendon can signal an end to their professional careers. But a consortium of scientists, led in part by USC School of Dentistry researcher Songtao Shi, has identified unique cells within the adult tendon that have stem-cell characteristics - including the ability to proliferate and self-renew.

Researchers develop a long-acting growth hormone for use in human therapy

The new discovery could mean that children and adults with growth hormone disorders will not have to have injections as often, reducing the need for daily treatments.

Researchers chart the level of gene expression in melanoma cell lines

Other than visually inspecting the disease, doctors have no genetic blueprint to classify melanomas, a lethal form of skin cancer.

New understanding of malaria mosquito's olfactory system

By mapping a specialized sensory organ that the malaria mosquito uses to zero in on its human prey, an international team of researchers has taken an important step toward developing new and improved repellants and attractants that can be used to reduce the threat of malaria, generally considered the most prevalent life-threatening disease in the world.

'Mighty mice' made mightier

The Johns Hopkins scientist who first showed that the absence of the protein myostatin leads to oversized muscles in mice and men has now found a second protein, follistatin, whose overproduction in mice lacking myostatin doubles the muscle-building effect.
