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.

Study reveals dual role for Norrin/Frizzled-4 protein pair

Working with mice, Johns Hopkins researchers have shed light on the activity of a protein pair found in cells that form the walls of blood vessels in the brain and retina, experiments that could lead to therapeutic control of the blood-brain barrier and of blood vessel growth in the eye.

Study catalogs genetic variation of microbes that live in the gut

Our bodies contain far more microbial genes than human genes. And a new study suggests that just as human DNA varies from person to person, so too does the massive collection of microbial DNA in the intestine.

TSRI scientist to better define how brain organizes different types of memories among neurons

A scientist from the Florida campus of The Scripps Research Institute (TSRI) has been awarded approximately $2.5 million from the National Institute of Neurological Disorders and Stroke to better define how the brain organizes different types of memories among its neurons.

Tyk2 enzyme helps regulate obesity through differentiation of brown adipose tissue

Approximately 68 percent of U.S. adults are overweight or obese, according to the National Cancer Institute, which puts them at greater risk for developing cancer, cardiovascular disease, diabetes and a host of other chronic illnesses. But an international team of scientists led by Virginia Commonwealth University Massey Cancer Center researcher Andrew Larner, M.D., Ph.D., has successfully reversed obesity in mice by manipulating the production of an enzyme known as tyrosine-protein kinase-2 (Tyk2).

Researchers describe role of calcium in ability of Yersinias to cause disease

A more than 50-year-old question has now been answered. Chemists and microbiologists at the Biological Chemistry Center at Umeå University in Sweden are now able to describe in detail the role of calcium in the ability of the plague bacterium Yersinias to cause disease.

Reductions in fine particulate matter may improve life expectancy in the U.S.

A new study led by researchers at Harvard School of Public Health (HSPH) has found an association between reductions in fine particulate matter and improved life expectancy in 545 counties in the U.S. from 2000 to 2007. It is the largest study to date to find beneficial effects to public health of continuing to reduce air pollution levels in the U.S.

Scientists determine how two proteins help create organelles

Scientists at The Scripps Research Institute (TSRI) have determined how two proteins help create organelles, or specialized subunits within a cell, that play a vital role in maintaining cell health. This discovery opens the door for research on substances that could interfere with the formation of these organelles and lead to new therapies for cancer.

Scientists sequence DNA of biopsied tissue from colon polyps

The causes underlying the development of certain types of common cancers have not yet been elucidated. In order to better determine the origin and the sequence of events responsible for the onset of colon cancer, the teams led by Thanos Halazonetis and Stylianos Antonarakis, professors at the University of Geneva (UNIGE), Switzerland, have sequenced the DNA of biopsied tissue from colon polyps.

Researchers uncover molecular structure of master regulator central to melanoma

With the X-ray vision of DESY's light source DORIS, a research team from Hamburg and Iceland has uncovered the molecular structure of a master regulator central to the most deadly form of skin cancer, melanoma.

JQ1 cancer drug may be useful in purging latent HIV infection

Breakthrough drugs have made it possible for people to live with HIV longer than ever before, but more work must be done to actually cure the disease. One of the challenges researchers face involves fully eradicating the virus when it is latent in the body.
