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.

Cell division linked to oxygen levels: Johns Hopkins research

Cells grow abundant when oxygen is available, and generally stop when it is scarce. Although this seems straightforward, no direct link ever has been established between the cellular machinery that senses oxygen and that which controls cell division. Now, in the June 10 issue of Molecular Cell, researchers at Johns Hopkins report that the MCM proteins, which promote cell division, also directly control the oxygen-sensing HIF-1 protein.

New opportunities to save another 6.4 million lives

Vaccinating children around the world against infectious diseases has saved the lives of millions over the past several decades. Now new opportunities exist to overcome remaining challenges-and save another 6.4 million lives over the current decade, according articles in the June 2011 edition of Health Affairs. The issue was produced under the journal's grant from the Bill & Melinda Gates Foundation.

Research provides better understanding of interplay between genomes of malaria parasites, humans

For tens of thousands of years, the genomes of malaria parasites and humans have been at war with one another. Now, University of Pennsylvania geneticists, in collaboration with an international team of scientists, have developed a new picture of one way that the human genome has fought back.

Neuroscientists uncover the source of visual system's 'false alarms'

On rare occasion, the light-sensing photoreceptor cells in the eye misfire and signal to the brain as if they have captured photons, when in reality they haven't. For years this phenomenon remained a mystery. Reporting in the June 10 issue of Science, neuroscientists at the Johns Hopkins University School of Medicine have discovered that a light-capturing pigment molecule in photoreceptors can be triggered by heat, as well, giving rise to these false alarms.

European Bioinformatics Institute drives genomics research with GÉANT

The European Molecular Biology Laboratory’s European Bioinformatics Institute (EMBL-EBI), which hosts the world’s largest public collection of molecular biology databases, is using the pan-European GÉANT research network and JANET, the UK research network, to help biologists share vital data across the globe.

The ‘decade of vaccines’ has the potential to save lives, many challenges ahead

Vaccinating children around the world against infectious diseases has saved the lives of millions over the past several decades. Now new opportunities exist to overcome remaining challenges—and save another 6.4 million lives over the current decade, according articles in the June 2011 edition of Health Affairs. The issue was produced under the journal’s grant from the Bill & Melinda Gates Foundation.

Research provides new insights into how cilia are assembled on the cell surface

Body cells detect signals that control their behavior through tiny hairs on the cell surface called cilia. Serious diseases and disorders can result when these cilia do not work properly.

Key molecule of vascular system directs axons during neural circuit formation

Dr. Fr-d-ric Charron, researcher at the Institut de recherches cliniques de Montr-al (IRCM), and his team have shown for the first time that a key molecule of the vascular system directs axons during the formation of neural circuits.

Researchers identify key molecule responsible for breast tumor metastasis

Researchers at Albert Einstein College of Medicine of Yeshiva University have identified a key player in the spread of breast cancer. The findings, published today in the online edition of Nature, identify a critical molecule that helps cancer spread beyond the primary tumor.

UC Davis and BGI partner to conduct large-scale genome sequencing and functional genomics programs

The University of California, Davis, and BGI, the world's largest genome sequencing institute, agreed today (June 8) to form a partnership to conduct large-scale genome sequencing and functional genomics programs, focusing initially on the areas of food security; human and animal health and wellness; and biodiversity and environmental health.

McGill researcher develops speedier technique for predicting protein folding pathways

Protein folding has nothing to do with laundry. It is, in fact, one of the central questions in biochemistry. Protein folding is the continual and universal process whereby the long, coiled strings of amino acids that make up proteins in all living things fold into more complex three-dimensional structures.

New poll finds 63% of Massachusetts residents support health care law enacted in 2006

A new poll by the Harvard School of Public Health and The Boston Globe finds 63% of Massachusetts residents support the health care reform legislation enacted in 2006, 21% oppose it while 6% are not sure and 9% have not heard or read about the law.

Silencing two microRNAs may help treat age-related macular degeneration

Blocking two tiny molecules of RNA - a chemical cousin of DNA - appears to suppress the abnormal growth of blood vessels that occurs in degenerative eye disorders, UT Southwestern Medical Center researchers have found.

New understanding of muscle growth and repair

Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell’s territory, eventually forcing the cells to combine.

GW researchers demonstrate Mta1 gene's role in survival of schistosomes

By using mice lacking a crucial gene that controls the process of chromatin remodeling of cytokines including those responsible for inflammation and comparing them to normal wild type mice with the gene, researchers at the George Washington University School of Medicine and Health Sciences have shown that the gene, Mta1, is essential for the parasite Schistosoma haematobium to establish a productive infection and survival in the host.

Insight into understanding of normal muscle growth

Revealing another part of the story of muscle development, Johns Hopkins researchers have shown how the cytoskeleton from one muscle cell builds finger-like projections that invade into another muscle cell's territory, eventually forcing the cells to combine.

New approach for treatment of infections of urinary tract

One in three women will be faced at least once in her life with cystitis, for some the start of a constantly recurring infection. Cystitis is caused by Escherichia coli bacteria which fasten on to the wall of the bladder by means of thread-like structures (pili).

Decreasing iron-storing protein expression can enhance action of brain cancer therapy: Researchers

Brain cancer therapy may be more effective if the expression of an iron-storing protein is decreased to enhance the action of therapeutic drugs on brain cancer cells, according to Penn State College of Medicine researchers.

Scientists discover new compound that inhibits bitterness

Although bitterness can sometimes be desirable - such as in the taste of coffee or chocolate - more often bitter taste causes rejection that can interfere with food selection, nutrition and therapeutic compliance. This is especially true for children. Now, scientists from the Monell Center and Integral Molecular describe the discovery of a compound that inhibits bitterness by acting directly on a subset of bitter taste receptors.
