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.

Compound called apolipoprotein B in blood better at predicting coronary heart disease in Chinese people

Scientists report in the November 2007 issue of the Journal of Lipid Research that the concentration of a compound called apolipoprotein B in the blood is better at predicting whether Chinese have coronary heart disease – in which fatty deposits clog arteries that supply blood and oxygen to the heart – than other substances such as blood cholesterol levels.

Research shows how stem cells decide to become either skeletal or smooth muscle

Researchers have discovered a key protein that controls how stem cells "choose" to become either skeletal muscle cells that move limbs, or smooth muscle cells that support blood vessels, according to a study published in the Proceedings of the National Academy of Sciences (PNAS).

New insight on jumping genes

Keck Graduate Institute (KGI) announced that Dr. Animesh Ray, KGI professor and director of KGI's PhD program, has published a paper in the international online journal PLoS ONE that sheds new light on the evolution of moveable genetic elements, or "jumping genes."

Researchers report most complete list so far of the proteins present in the cerebral cortex

Researchers report in the October 2007 issue of Molecular & Cellular Proteomics the most complete list so far of the proteins present in the cerebral cortex – the outermost layer of the brain that plays a central role in memory, language, cognition, and consciousness.

Proteins found that could be used to improve diagnosis of hepatocellular carcinoma

Researchers report in the October 2007 issue of Molecular & Cellular Proteomics that they have identified proteins that could be used to improve the diagnosis of hepatocellular carcinoma, the most common type of liver cancer.

Improving diagnosis of cancer by detecting protein-sugar structures

Researchers report in the October 2007 issue of Molecular & Cellular Proteomics that they have developed a new way of detecting the abnormal presence of complexes of sugars and proteins in the blood of cancer patients, thus providing a new tool for cancer diagnosis.

Fraunhofer pharmaceutical agent speeds drug development

It takes a great deal of time and money to develop a new drug. At Biotechnica in Hanover from October 9 to 11, the Fraunhofer Life Sciences Alliance will demonstrate how a pharmaceutical agent can make its way more quickly from the research laboratory to the pharmacy.

Controlling for size may also prevent cancer

Scientists at Johns Hopkins recently discovered that a chemical chain reaction that controls organ size in animals ranging from insects to humans could mean the difference between normal growth and cancer.

Test for lung cancer looks for discomforting quiet among protective genes

When it is quiet – "almost too quiet" – in movies, it is a sign that something is about to go wrong for the good guys.

Breakthrough in cardiovascular research

Cholesterol contributes to atherosclerosis - a condition that greatly increases the risk of heart attack and stroke - by suppressing the activity of a key protein that protects the heart and blood vessels, researchers at the Saint Louis University School of Medicine have found.

Secrets of protein folding revealed

A team led by biophysicist Jeremy Smith of the University of Tennessee and Oak Ridge National Laboratory (ORNL) has taken a significant step toward unraveling the mystery of how proteins fold into unique, three-dimensional shapes.

Cellular spelunking

The surface of fat cells contains many small pockets called caveolae (because they look like caves in an electron microscope).

High fat diet and exercise stimulate the breakdown of fats

Scientists report in the October issue of the Journal of Lipid Research that when either lean or obese individuals exercise after eating a high fat meal, their fats are broken down and oxidized in skeletal muscle, making them healthier.

Study looks at Atorvastatin and cholesterol

Scientists report in the October issue of the Journal of Lipid Research new details about how a drug used against heart disease helps to unclog blood vessels from an excess of cholesterol and fats.

How can a medical center foster a culture of ethics in research?

An article published in the September issue of Academic Medicine, titled "Developing a Research Ethics Consultation Service to Foster Responsive and Responsible Clinical Research," argues for the importance of collaboration between researchers and ethicists and describes the establishment of a new Research Ethics Consultation Service at Weill Cornell Medical College.
