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.

Transgenomic and A. Menarini Diagnostics enter distribution agreement for mutation detection systems

Transgenomic, Inc. and A. Menarini Diagnostics today announced an exclusive distribution agreement for Transgenomic's SURVEYOR Scan and WAVE MCE (Micro-Capillary Electrophoresis) Mutation Detection system to its network of over 2,000 pathologists throughout Europe.

Researchers discover two effective cancer killers

Researchers at the University of Southern California have identified two molecules that may be more effective cancer killers than are currently available on the market.

'Medicine that grows' confronts antibiotics resistance

It's been called "the trots," "Montezuma's Revenge," "the runs" and worse. But no matter the name, when it strikes, victims wish for a medicine that could go straight to the offending bacteria to quickly knock it dead.

Cancer cells maintain rapid proliferation due to PK-M2 enzyme

Cancer cells maintain their life-style of extremely rapid growth and proliferation thanks to an enzyme called PK-M2 (pyruvate kinase M2) that alters the cells' ability to metabolize glucose - a phenomenon known as the Warburg effect.

Elevated body temperature helps certain types of immune cells to work better

With cold and flu season almost here, the next time you're sick, think twice before taking something for your fever. That's because scientists have found more evidence that elevated body temperature helps certain types of immune cells to work better.

Peroxiredoxin enzyme holds key to ageing process

By consuming fewer calories, ageing can be slowed down and the development of age-related diseases such as cancer and type 2 diabetes can be delayed. The earlier calorie intake is reduced, the greater the effect. Researchers at the University of Gothenburg have now identified one of the enzymes that hold the key to the ageing process.

Scientists identify key mechanism of tumor metastasis

Scientists at Dalhousie University in Nova Scotia have identified a key mechanism of metastasis that could lead to blocking tumor growth if their findings are confirmed.

Researchers shed light on inner workings of endocycle

An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass.

Researchers identify FMRP protein as key player in RNA editing

The most common form of heritable cognitive impairment is Fragile X Syndrome, caused by mutation or malfunction of the FMR1 gene. Loss of FMR1 function is also the most common genetic cause of autism. Understanding how this gene works is vital to finding new treatments to help Fragile X patients and others.

Research breakthrough in lung regeneration

Scientists at A*STAR'S Genome Institute of Singapore (GIS) and Institute of Molecular Biology (IMB), have made a breakthrough discovery in the understanding of lung regeneration. Their research showed for the first time that distal airway stem cells (DASCs), a specific type of stem cells in the lungs, are involved in forming new alveoli to replace and repair damaged lung tissue, providing a firm foundation for understanding lung regeneration.

Number of polio cases in Pakistan exceeds total number reported in three other endemic countries, report says

According to a report published earlier this month in Virology Journal by a team at the bioinformatics laboratory of the Centre for Excellence in Molecular Biology (CEMB) in Lahore, Pakistan, that country is reporting more polio cases than Nigeria, India and Afghanistan -- the three other countries where the disease is endemic -- combined, SciDev.Net reports.

Scientists describe how protein acts as courier in cell signaling pathways

Normal development, from fertilized egg to adult organism, depends on each cell receiving proper instructions from its environment. In response to such incoming information, receptors on a cell's surface send signals to the nucleus that tweak gene expression and control cellular function.

VitaYeast project to curb global malnutrition

Any way you slice it, bread that contains critical nutrients could help combat severe malnutrition in impoverished regions. That is the goal of a group of Johns Hopkins University undergraduate students who are using synthetic biology to enhance common yeast so that it yields beta carotene, the orange substance that gives carrots their color. When it's eaten, beta-carotene turns into vitamin A.

Gestational BPA exposure associated with behavior, emotional problems in young girls

Exposure in the womb to bisphenol A (BPA) - a chemical used to make plastic containers and other consumer goods - is associated with behavior and emotional problems in young girls, according to a study led by researchers at Harvard School of Public Health (HSPH), Cincinnati Children's Hospital and Medical Center, and Simon Fraser University in Vancouver, British Columbia.

DFG announces establishment of twelve research units

The Deutsche Forschungsgemeinschaft has established nine new Research Units and three Clinical Research Units. The decision was made by the Joint Committee of Germany's central research funding organisation at its October meeting in Bonn.

Women with MET genetic variant and autoantibodies more likely to have autistic children

A study by researchers at UC Davis has found that pregnant women with a particular gene variation are more likely to produce autoantibodies to the brains of their developing fetuses and that the children of these mothers are at greater risk of later being diagnosed with autism.

OPHN1 protein mediates mGluR-dependent longterm depression at synapses

Scientists at Cold Spring Harbor Laboratory (CSHL) have solved part of a puzzle concerning the relationship between changes in the strength of synapses - the tiny gaps across which nerve cells in the brain communicate - and dysfunctions in neural circuits that have been linked with drug addiction, mental retardation and other cognitive disorders.

New form of respiratory distress syndrome in newborn mice

A discovery by scientists at the Salk Institute for Biological Studies might explain why some premature infants fail to respond to existing treatments for a deadly respiratory distress syndrome (RDS) and offers clues for new ways to treat the breathing disorder.

FSU biologists devise new way to watch how cells move

For better and for worse, human health depends on a cell's motility -- the ability to crawl from place to place. In every human body, millions of cells -are crawling around doing mostly good deeds --- though if any of those crawlers are cancerous, watch out.
