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.

Mighty mouse gene works the same way in humans

By studying the genes of a German child born with unusually well developed muscles, an international research team has discovered the first evidence that the gene whose loss makes "mighty mice" also controls muscle growth in people.

Muscular German boy sheds new light on muscle development and genetics

By studying the genetic make up of a German boy born with unusually well developed muscles, an international research team has discovered the first evidence that the gene whose loss makes "mighty mice" also controls muscle growth in people.

A natural molecule that blocks a key bacterial enzymes could lead to a new generation of antibiotics

Rutgers scientists have deciphered the complex mechanics of microcin J25 (MccJ25), a tiny, natural molecule that acts like a cork in a bottle to block a key bacterial enzyme – potentially leading to a new generation of antibiotics.

£11.5m for new structural proteomics research

The Biotechnology and Biological Sciences Research Council (BBSRC) has announced that two new research projects will together receive nearly £11.5m under the Structural Proteomics of Rational Targets Initiative (SPORT).

Australian researchers awarded funding for new HIV vaccines

Australian researchers at Monash University have been awarded $488,125 in development grants by the National Health and Medical Research Council (NHMRC) for projects exploring new vaccines for HIV, the development of medical diagnostic devices and the development of drugs to treat metastatic cancers.

New whole body positron emission tomography (PET) imaging allows scientists to watch as immune system respond to tumors or infection

Compared to the snapshot views of the immune system from tumor biopsies or blood assays, this whole body imaging allows scientists to track how the immune response changes, and the tumor or infection responds, throughout the different phases of immune response and over long periods of time.

University of Cambridge to generate antibodies

The University of Cambridge has announced a licensing agreement with Human-Human Hybridoma, Inc. (3H) to exploit a human myeloma cell line (Karpas-707H) that can be used in research and for the production of human monoclonal antibodies.

Significance of the discovery of anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis

Dr. Fraser discusses, for the first time, the significance of the discovery of anthrax toxin genes in a naturally occurring microbe other than Bacillus anthracis, the bacterium that causes anthrax.

Biologist has identified gene patterns that characterize a biologically distinct subtype of estrogen receptor negative breast tumor

University of North Carolina molecular biologist Charles Perou has identified the pattern of genes that characterize a biologically distinct subtype of estrogen receptor negative breast tumor.

Possible therapeutic approach to lowering LDL cholesterol and homocysteine levels

Canadian scientists report that mice genetically altered so as to lack either of the two different pathways through which humans, mice, and other animals provide lipids for high density and low density lipoproteins (HDL and LDL) did not appear to suffer any ill effects. But animals from both groups had markedly lower levels of cholesterol in their blood stream.

Research laboratory at the forefront of the science of metabolomics

A new $1.8 million research laboratory will catapult Iowa State University to the forefront of the science of metabolomics.

Four critical components of cells' protein-building machine don't do what scientists had long assumed

In the hunt for these details, scientists have focused on four RNA building blocks, or nucleotides, deep within the machine that are identical in every species, from bacteria to humans. Because they sit where the protein chain is actually built, these "universally conserved" nucleotides in the ribosome were thought to help that process.

New target of a cancer-causing gene

Researchers from the Johns Hopkins Bloomberg School of Public Health and other institutions have identified a new target of a cancer-causing gene.

Finding overturns long held ideas about how cells build proteins

Writing in the May 28 issue of Cell, Johns Hopkins researchers report that four critical components of cells' protein-building machine don't do what scientists had long assumed.

3 or 4 glasses of wine a week can kill cancer cells

It’s well known that drinking red wine in moderation can have some health benefits, mainly attributed to a compound called resveratrol. Now, scientists at the University of Virginia Health System have discovered how.

Some smokers may be genetically predisposed to chronic obstructive pulmonary disease

In her study, Ohar looked at more than 500 men and women age 40 and older who had smoked 20 years or more. She found that a variation of the macrophage scavenger receptor gene (MSR-1) is related to the development of airways obstruction in some patients who smoke cigarettes.

Cell division can be halted in multiple ways, with implications for cancer

Brown University researchers have found that there are multiple independent ways to stop cell division, a phenomenon that prevents the spread of genetic mutation, which can make cells cancerous. Results of this research, along with an accompanying editorial, were published in the current issue of the journal Molecular Cell.

Scientists have sped up a common jumping gene found in the human genome

Johns Hopkins scientists have transformed a common "jumping gene" found in the human genome into one that moves hundreds of times more often than normal in mouse and human cells.

New study of tumor genetics may help to treat patients with head and neck cancer

Head and neck tumors account for more than 40,000 new cancers annually in the United States. The most common of these is squamous cell carcinoma. Prognosis is based largely on location and size of the tumor, and if the cancer has spread, or metastasized, to lymph nodes and distant sites in the body.
