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.

Critical biochemical pathways linked to the aging of human muscle identified

A study led by researchers at the University of California, Berkeley, has identified critical biochemical pathways linked to the aging of human muscle. By manipulating these pathways, the researchers were able to turn back the clock on old human muscle, restoring its ability to repair and rebuild itself.

NK cells keep T cells in check: Study

Natural killer, or NK cells, are part of our innate immune system. A healthy body produces them to respond early during infection. They are activated and they kill cells infected with a given virus.

Enzyme that helps make tuberculosis resistant to a human's natural defense system identified

Researchers at Iowa State University have identified an enzyme that helps make tuberculosis resistant to a human's natural defense system. Researchers have also found a method to possibly neutralize that enzyme, which may someday lead to a cure for tuberculosis.

Brdt protein in developing sperm cells direct tight re-packaging of sperm DNA

In the quest for speed, olympic swimmers shave themselves or squeeze into high-tech super-suits. In the body, sperm are the only cells that swim and, as speed is crucial to fertility, have developed their own ways to become exceptionally streamlined. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg and Grenoble, the Institut de Biologie Structurale (IBS) and the Institut Albert Bonniot, both also in Grenoble, have been studying the secrets of speedy sperm.

New center for gastrointestinal cancer research established

Georgetown University Medical Center today announced the creation of a center that may help advance a cure for one of the deadliest forms of cancer. The Otto J. Ruesch Center for the Cure of Gastrointestinal (GI) Cancers will fund gastrointestinal cancer research, drug discovery and patient advocacy efforts at the Georgetown Lombardi Comprehensive Cancer Center.

Scientists use new techniques to explore vocal learning at molecular level

You can learn a lot from an animal. By manipulating the DNA of mice, flies, frogs and worms, scientists have discovered a great deal about the genes and molecules behind many of life's essential processes. These basic functions often work about the same in people as they do in "model" animals.

Researchers discover potential treatment for Friedreich's ataxia

Using clever chemistry, a Scripps Research team has pinpointed the enzyme target of a drug group that stops the progression of the devastating disease Friedreich's ataxia in mice and may do the same for humans. The findings, developed in collaboration with scientists from Repligen Corporation, help advance this treatment approach one step closer toward human clinical trials, which will be a welcome event for disease sufferers who currently have few treatment options.

Macrophages play a crucial role in muscle regeneration

For scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, what seemed like a disappointing result turned out to be an important discovery.

Novel cleavage sites for enzyme caspase-3 identified

Investigators at Burnham Institute for Medical Research (Burnham) have identified novel cleavage sites for the enzyme caspase-3 (an enzyme that proteolytically cleaves target proteins). Using an advanced proteomic technique called N-terminomics, Guy Salvesen, Ph.D., professor and director of the Apoptosis and Cell Death Research program of Burnham's NCI-designated Cancer Center, and colleagues determined the cleavage sites on target proteins and found, contrary to previous understanding, that caspase-3 targets α-helices as well as unstructured loops.

Geron and Corning develop synthetic surface that supports the growth and differentiation of hESCs

Corning Incorporated (NYSE: GLW) and Geron Corporation (Nasdaq: GERN) today announced the successful development of novel synthetic surface matrices demonstrated to enhance and support the scalable manufacturing and growth of human embryonic stem cells (hESCs).

H1N1 infected people continue to shed live virus days after the symptoms

ABC News and other outlets are reporting that two studies released on Tuesday suggest that people infected with the H1N1 virus continue to shed virus after the point where current recommendations say they can resume their normal activities.

Protein aggregation is linked to many conformational diseases

Researchers at the Department of Biochemistry and Molecular Biology of Universitat Autònoma de Barcelona (UAB) have revealed the process by which proteins with a tendency to cause conformational diseases such as amyotrophic lateral sclerosis, familial amyloidotic polyneuropathy, familial amyloidotic cardiomyopathy, etc. finally end up causing them.
