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.

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.

Scientists may have figured out how to use stem cells to regenerate lost or injured tissue

In experiments with fruit flies, Johns Hopkins scientists have restored the insect's sperm-making stem cells by triggering cells on the way to becoming sperm to reverse course. The unexpected findings are described in the May 13 issue of Science.

Scientists move closer toward treatment for degenerative diseases

Scientists at McGill University's Faculty of Medicine have discovered a key step that will provide new targets for treatments of many degenerative diseases such as Alzheimer's, Cystic Fibrosis and Diabetes.

Biochip technology to revolutionise the pharmaceutical industry

Advancements in biotechnology have culminated in its integration with semiconductor technologies such as micro-electromechanical systems, resulting in the evolution of biochips. Biochips provide pharma companies with sophisticated tools for speedy development of drugs and accurate diagnosis and understanding of biological mechanisms.

New chink in the cellular armor of tuberculosis (TB) and leprosy

The family of bacteria that causes tuberculosis (TB) and leprosy are notoriously sturdy. And although the diseases they cause have been held in check for the past 50 years by antibiotics, some strains are becoming increasingly resistant to existing therapy.

Genetic breakthrough in tracing the cause of a rare kidney and liver disorder

Birmingham scientists have made a genetic breakthrough in tracing the cause of a rare kidney and liver disorder. ARC syndrome means babies are born with impairment to kidney and liver function, bleeding problems and weak muscles. This usually leads to early death. The gene which causes this condition has been identified.

New studies put spotlight on replicative capacity of beta cells

Researchers at Harvard University and the Howard Hughes Medical Institute (HHMI) have discovered that insulin-producing beta cells in the pancreas that are attacked in type 1 diabetes are replenished through duplication of existing cells rather than through differentiation of adult stem cells.

New hope for advances in treatment methods for AIDS, Alzheimer's and age-related blindness

Pharmaceutical science leaders from the FDA, research institutions and top pharmaceutical companies will gather at the 2004 AAPS National Biotechnology Conference, AAPS' spring annual meeting.

New Australian VR center to give medical students the ability to feel virtual skin, muscle, tendon and bone

And later this year, the facility will be upgraded to include “haptic” capacity, or the ability to recognise the sense of touch – such as giving medical students the ability to “feel” the difference between virtual skin, muscle, tendon or bone.

Study shows those with weak immune systems should avoid the shower

A study out of the San Diego State University Center for Microbial Sciences reveals that hundreds of millions of colorful bacteria thrive on shower curtains, waiting to attack those who think they are getting clean.

$11 million for lung injury research

Northwestern University has received an $11 million Program Project Grant (PPG) from the National Institutes of Health to define the mechanisms that cause changes in the alveolar epithelium during lung injury.

Researchers make millions upon millions of drug-like peptides quickly and efficiently

Two Johns Hopkins scientists have figured out a simple way to make millions upon millions of drug-like peptides quickly and efficiently, overcoming a major hurdle to creating and screening huge "libraries" of these super-short proteins for use in drug development.

New techniques to search the yeast genome for genes that help keep copied chromosomes together

Johns Hopkins scientists have successfully used new techniques to search the yeast genome for genes that help keep copied chromosomes together, protecting the integrity of the organism's genetic material during cell division.

Link between iron regulation and the immune system

Patients with chronic inflammatory disorders, including infections, inflammatory bowel disease, arthritis and cancer, commonly become anemic. The anemia can make them sicker, is sometimes severe enough to require a blood transfusion, and responds only partially to current treatments.

World's largest drug-like library comprising 100 million diverse compounds synthesised in a single test tube

Nuevolution A/S, a privately held drug discovery company today announced that it has generated what it believes to be the world's largest drug-like library comprising 100 million diverse compounds synthesised in a single test tube.

New tool for study of carbohydrates could aid drug research

While many dieters are trying to cut carbs, a University of New Hampshire (UNH) biochemist has invented a way to capture them so scientists can more easily study their structure.

New process to extract proteins from membranes by using chemicals

Proteins are complex compounds that are essential for the growth and repair of tissue. While scientists understand much about the structure and stability of water-soluble proteins that ‘float’ around in humans, they know very little about the shape and stability of proteins that are embedded, or folded, into the lipid membrane of cells. Such membrane proteins make up about 30 percent of all proteins in the body.
