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.

Researchers watch bacteria and antibiotics at the atomic level

A new understanding of an enzyme important for the transfer of genetic information in bacteria may help scientists improve current antibiotics and also create antibiotics that are less vulnerable to resistance.

Scientists shed new light on how microRNAs carry out their function

MicroRNAs became the stars of the RNA universe when, in 2001, scientists found that these short RNAs can control whether or not genes are expressed.

New understanding of Sly Syndrome

The scientist who discovered “Sly Syndrome” nearly four decades ago and a team of colleagues at Saint Louis University are a step closer to finding an approach to treat the rare genetic disease.

Itchy and scratchy gene discovered

Itching for a better anti-itch remedy? Your wish may soon be granted now that scientists at Washington University School of Medicine in St. Louis have identified the first gene for the itch sensation in the central nervous system.

Genetic susceptibility to diet-induced obesity

Researchers at the Monell Chemical Senses Center have identified a genetically-transmitted metabolic defect that can lead to obesity in some individuals.

Cholesteryl ester transfer protein may also influence how fat cells store fat

Scientists have shown for the first time that a protein involved in the transfer of fat in the blood may also influence how fat cells store fat.

Lubert Stryer wins National Medal of Science

Neurobiologist Lubert Stryer, MD, of the Stanford University School of Medicine, will receive the nation's highest scientific honor, the National Medal of Science, for his achievements in a wide range of fields that included the development of a DNA chip used in genetics.

Jefferson scientist shares patent for DNA analysis

A basic scientist in the Department of Surgery at Jefferson Medical College and the Kimmel Cancer Center at Jefferson has shared a patent on what may someday be a ubiquitous tool in DNA analysis.

Research on proteases and pathological processes

A research group of the UAB Institute of Biotechnology and Biomedicine and the UAB Department of Biochemistry and Molecular Biology, directed by Francesc Xavier Aviles, is the coordinator of a European project aimed at studying proteases with fluorescent molecules that allow their monitoring in healthy and pathological situations.

Consortium to fight malaria caused by Plasmodium vivax

The CRESIB has presented the research programme on malaria by Plasmodium vivax, a parasite causing over 70 million yearly cases of malaria in the world.

Inverse relationship between mortality rates and performance in the hospital quality alliance measures

A new study from the Harvard School of Public Health (HSPH) shows that patients who go to hospitals ranked higher according to specific quality measures have a lower chance of dying than patients treated at lower-ranked hospitals.

New target for muscular dystrophy drug therapy

Researchers at the University of Pennsylvania School of Medicine report how the gene for utrophin, which codes for a protein very similar to dystrophin, the defective protein in Duchenne muscular dystrophy (DMD), puts the brakes on its own expression in muscle cells, thereby suggesting a new target for treatment.

Genes play a large role in sour taste perception

Scientists at the Monell Chemical Senses Center report that genes play a large role in determining individual differences in sour taste perception.

How immune cells catch pathogens

To protect us from disease our immune system employs macrophages, cells that roam our body in search of disease-causing bacteria.

Cancer-causing enzyme could be stopped

Scientists from the MRC's Laboratory of Molecular Biology (LMB) and the Albert Einstein College of Medicine have discovered a way to stop an enzyme responsible for many cancers.

11 Jul 2007

How immune cells catch pathogens

To protect us from disease our immune system employs macrophages, cells that roam our body in search of disease-causing bacteria. With the help of long tentacle-like protrusions, macrophages can catch suspicious particles, pull them towards their cell bodies, internalise and destroy them.

Autophagy may accelerate decompensated heart failure

Autophagy, a normal process by which cells eat their own proteins to provide needed resources to the body in times of stress, may paradoxically cause harm to hearts already weakened by disease, researchers from UT Southwestern Medical Center have found.

Orlistat weight loss drug points to new cancer treatments

Based on their surprising discovery that an obesity drug can kill cancer cells, scientists at Wake Forest University School of Medicine have made a new finding about the drug's effects and are working to design more potent cancer treatments.

Amoebae control cheating by keeping it in the family

No one likes a cheater, even a single-celled one. New research from Rice University shows how cooperative single-celled amoebae rely on family ties to keep cheaters from undermining the health of their colonies.
