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.

Loss of elasticity and protein breakdown cause pelvic organ prolapse

A gynecologist and a molecular biologist at UT Southwestern Medical Center have collaborated to show for the first time that pelvic organ prolapse - a condition in which the uterus, bladder or vagina protrude from the body - is caused by a combination of a loss of elasticity and a breakdown of proteins in the vaginal wall.

Research could pave way toward new anti-bacterial treatments

A group of proteins that act as the body's built-in line of defense against invading bacteria use a molecular trick to induce bacteria to destroy themselves, researchers at the Indiana University School of Medicine have determined. The research could point the way toward new anti-bacterial treatments that could take on bacteria that are resistant to antibiotics.

Scientists invent Monolayer Stress Microscopy to measure physical forces during collective cellular migration

The physical forces that guide how cells migrate-how they manage to get from place to place in a coordinated fashion inside the living body- are poorly understood. Scientists at the Harvard School of Public Health and the Institute for Bioengineering of Catalonia have, for the first time, devised a way to measure these forces during collective cellular migration.

Researchers uncover new details of unusual biological mechanism in brains of diverse species

Researchers at the University of California, San Diego School of Medicine have uncovered new details of an unusual biological mechanism in the brains of diverse species that not only helps regulate how their brains develop, but also how they function later in life. The discovery could lead to new biomarkers for specific neurological diseases in humans and, possibly, the development of drugs to cure them.

GIS discovery could help generate stem cells more efficiently for biomedical applications

A team of scientists from Genome Institute of Singapore (GIS) of the Agency for Science, Technology and Research (A*STAR) have shown how proteins involved in controlling genes work together to carry out their functions in stem cells and demonstrated for the very first time, how they can change interaction partners to make other types of cells.

Study offers new understanding of cell signaling networks tied to diabetes and cancer

Researchers at the University of Texas Medical Branch at Galveston and the University of California-San Diego School of Medicine have published a study that offers a new understanding of a protein critical to physiological processes involved in major diseases such as diabetes and cancer. This work could help scientists design drugs to battle these disorders.

Over-activation of single gene promotes leukemia, but its loss causes liver cancer

An international team of researchers, led by scientists at the University of California, San Diego School of Medicine, and the Eastern Hepatobiliary Surgery Hospital in China, say a human gene implicated in the development of leukemia also acts to prevent cancer of the liver.

Scientists identify 'de novo' genetic mutations in autism spectrum disorder children

Scientists at the University of Washington (UW) Department of Genome Sciences have identified several sporadic or "de novo" genetic mutations in children with autism spectrum disorder. The researchers applied leading edge molecular biology techniques and massively parallel sequencing to simultaneously examine all of the protein coding portions of the genome, collectively called the exome.

Super-resolution microscopy technique reveals how and why cell's defenses fail against plague

Researchers at Sandia National Laboratories have developed a super-resolution microscopy technique that is answering long-held questions about exactly how and why a cell's defenses fail against some invaders, such as plague, while successfully fending off others like E.coli.
