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.

RNAi screen identifies Brd4 as a therapeutic target for acute myeloid leukemia

Scientists at Cold Spring Harbor Laboratory (CSHL) and five other institutions have used an unconventional approach to cancer drug discovery to identify a new potential treatment for acute myeloid leukemia.

New research highlights urgent need to develop specific guidelines for HIV-infected children

Children with HIV have persistently high levels of cholesterol and other lipids during treatment with antiretroviral medications, according to a pair of studies in JAIDS: Journal of Acquired Immune Deficiency Syndromes.

New approach to overcome complexities of developing more effective drugs for treating diseases

Pharmaceutical scientists typically face a meager five percent success rate for anti-cancer drugs in clinical trials. To help improve this success rate, Japanese scientists, led by Dr. Tetsuya Terasaki, one of the top pharmaceutical scientists focused on drug transporters, have developed a new approach designed to overcome complexities of developing new, more effective drugs to treat diseases, including cancer.

Federal appeals court partially reverses ruling in BRCA patents case

In a 2-1 decision, a federal appeals court today partially reversed a lower court's ruling in a case challenging patents on two human genes, BRCA1 and BRCA2, associated with hereditary breast and ovarian cancer. The court ruled that companies can obtain patents on the genes but cannot patent methods to compare those gene sequences.

Lack of TLR1 surface expression linked with increased susceptibility to tuberculosis

Are you genetically predisposed to tuberculosis? Scientists may now be able to answer this question and doctors may be able to adjust their therapeutic approach based on what they learn. That's because new research presented in the Journal of Leukocyte Biology suggests that two frequent mutations in an immune system gene called TLR1 are responsible for cellular changes that ultimately make us less likely to resist the disease.

Researchers identify new plasma membrane sculpting protein

The research group of Professor Pekka Lappalainen at the Institute of Biotechnology, University of Helsinki, has identified a previously unknown mechanism which modifies the structure of plasma membranes in intestinal epithelial cells.

Myb protein suppression can help eliminate acute myelogenous leukemia

A team of scientists at Cold Spring Harbor Laboratory (CSHL) has laid bare the mechanism behind a phenomenon called oncogene addiction in mice suffering from a form of leukemia that mimics acute myelogenous leukemia (AML) in humans.

New device can produce blood-based diagnostic results in minutes

Samuel K. Sia, assistant professor of biomedical engineering at Columbia Engineering, has developed an innovative strategy for an integrated microfluidic-based diagnostic device-in effect, a lab-on-a-chip-that can perform complex laboratory assays, and do so with such simplicity that these tests can be carried out in the most remote regions of the world.

Resection of brain regions with fast ripples may improve seizure outcome in pediatric epilepsy: Study

New research focusing on high-frequency oscillations, termed ripples and fast ripples, recorded by intracranial electroencephalography, may provide an important marker for the localization of the brain region responsible for seizure activity.

Cigarette smoke exposure alters airway tissue in people with COPD

Cigarette smoke exposure fundamentally alters airway tissue from people with chronic obstructive pulmonary disease (COPD) at the cellular level, laying the groundwork for airway thickening and even precipitating precancerous changes in cell proliferation that may be self-perpetuating long after cigarette smoke exposure ends, according to Australian researchers.

SMRT DNA sequencing technology reveals genetic profile of German E. coli bacteria

An international team of scientists has successfully employed single molecule, real-time DNA sequencing technology from Pacific Biosciences of California, Inc. to provide valuable insights into the pathogenicity and evolutionary origins of the highly virulent bacterium responsible for the German E. coli outbreak.

IRCM geneticists discover an unsuspected organization of pituitary cells

A team of geneticists at the Institut de recherches cliniques de Montr-al (IRCM), directed by Dr. Jacques Drouin, made an unexpected discovery on hormone secretion. Contrary to common belief, the researchers found that pituitary cells are organized in structured networks. The scientific breakthrough was published yesterday by the scientific journal Proceedings of the National Academy of Sciences.

All football players do not get chronic traumatic encephalopathy

Preliminary results from the first four brains donated to the Canadian Sports Concussion Project at the Krembil Neuroscience Centre, TorontoWesternHospital, reveal that two of the four former Canadian Football League (CFL) players suffered from a brain disease known as Chronic Traumatic Encephalopathy (CTE), while two did not show signs of CTE.

Four-year study to test effectiveness of WHO Safe Childbirth program

Harvard School of Public Health (HSPH) has been awarded a $14.1 million, four-year grant from the Bill & Melinda Gates Foundation to test the effectiveness of an innovative checklist-based childbirth safety program in reducing deaths and improving outcomes of mothers and infants in 120 hospitals in India.

UK regulators approve Europe's first clinical trial of plant-derived antibody for HIV

UK regulators have approved Europe's first clinical trial of a monoclonal antibody produced from genetically modified plants. This landmark decision sets the stage for the testing, in humans, of an anti-HIV product made from genetically modified tobacco plants. It will open the door for trials of additional plant-derived medicines treating a range of diseases.

Microglia prune connections between neurons

Gardeners know that some trees require regular pruning: some of their branches have to be cut so that others can grow stronger. The same is true of the developing brain: cells called microglia prune the connections between neurons, shaping how the brain is wired, scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, Italy, discovered.

Cell biologists identify infection mechanism of adenoviruses

Mucosal epithelia do not have any receptors on the outer membrane for the absorption of viruses like hepatitis C, herpes, the adenovirus or polio, and are thus well-protected against pathogenic germs. However, certain viruses, such as the human immunodeficiency virus HIV, still manage to enter the body via the mucous membrane.
