Molecular Biology News and Research

RSS

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.

HIV and syphilis on the rise among MSM

Rates of HIV and syphilis are very high and rising among men who have sex with men (MSM) in New York City, reports a study in the November issue of JAIDS: Journal of Acquired Immune Deficiency Syndromes. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

New clues about connections among fat, inflammation and insulin resistance

In a new study, scientists report that they substantially curbed weight gain, improved metabolism, and improved the efficacy of insulin in mice by engineering them to express a specific human enzyme in their fat tissue. Although the obesity prevention came at the significant cost of widespread inflammation, the research offers new clues about the connections among obesity, insulin resistance and type 2 diabetes, and inflammation.

Amplification of ALK gene may drive rapid breast cancer metastasis

Amplification of anaplastic lymphoma kinase, which has been reported in other cancers such as non-small cell lung cancers, may be a primary driver of the rapid metastasis that patients with inflammatory breast cancer experience.

POPG inhibits influenza infections in cell cultures and mouse models

A natural lipid in the fluid lining the lungs inhibits influenza infections in both cell cultures and mouse models, according to researchers at National Jewish Health. These findings, combined with previous studies demonstrating effectiveness against respiratory syncytial virus, suggest that the molecule, known as POPG, may have broad antiviral activity.

Study: Genes that are active in brain are transcribed with special mechanism

Knowledge about the development of the nervous system is of the greatest importance for us to understand the function of the brain and brain disorders. Researchers at Uppsala University have examined the key step when genes are read and found that genes that are active in the brain are transcribed with a special mechanism.

'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.
