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.

How an opportunistic fungal pathogen knows when to attack

The opportunistic fungal pathogen Candida albicans inconspicuously lives in our bodies until it senses that we are weak, when it quickly adapts to go on the offensive. The fungus, known for causing yeast and other minor infections, also causes a sometimes-fatal infection known as candidemia in immunocompromised patients. An in vivo study, published in mBio, demonstrates how C. albicans can distinguish between a healthy and an unhealthy host and alter its physiology to attack.

Human neutrophil peptide 1 effectively prevents HIV entry into cells in multiple ways

Human defensins, aptly named antimicrobial peptides, are made in immune system cells and epithelial cells (such as skin cells and cells that line the gut). One of these peptides, human neutrophil peptide 1, under certain circumstances hinders HIV infection, but exactly how it works remains unclear.

Rutgers cell biologist to receive Presidential Early Career Award for Scientists and Engineers

Fewer than 100 researchers nationwide are chosen each year to receive the Presidential Early Career Award for Scientists and Engineers (PECASE), and this year Dr. Nihal Altan-Bonnet is one of the 96 to receive this honor.

Scientists demonstrate link between cancer and faulty differentiation of stem cells

Stem cells hold great promise for the medicine of the future, but they can also be a cause of disease. When these self-renewing, unspecialized cells fail to differentiate into diverse cell types, they can start dividing uncontrollably, leading to cancer. Already several decades ago, Weizmann Institute scientists were among the first to demonstrate the link between cancer and the faulty differentiation of stem cells. Now a new Weizmann Institute-led study, published in Molecular Cell, reveals a potential molecular mechanism behind this link.

Novel genomic sequencing method can help conduct in-depth analysis of single cells

Only by viewing a Georges Seurat painting at close range can you appreciate the hidden complexities of pointillism - small, distinct dots of color applied to form an image from a distance. Similarly, biologists and geneticists have long sought to analyze profiles of genes at the single cell level but technology limitations have only allowed a view from afar.

Protein associated with Huntington’s and other neurodegenerative diseases has several brain-specific forms

A protein essential for metabolism and recently associated with neurodegenerative diseases also occurs in several brain-specific forms. This discovery emerged in the course of a research project funded by the Austrian Science Fund FWF, the findings of which have now been published in the journal Human Molecular Genetics.

Researchers uncover protein structure that regulates blood cell formation and activity

A Finnish research team together with researchers from New York, USA, has uncovered a protein structure that regulates cell signalling and the formation of blood cells. The team's results, published in Nature Structural & Molecular Biology, the most prestigious journal in the field, shed light on the mechanisms at play in haematological disorders and provide new opportunities for the design of disease-specific treatment.

Scientists develop simple assay to diagnose 'superparasites'

Belgian scientists of the Institute of Tropical Medicine (ITM) in Antwerp, Belgium made a breakthrough in bridging high tech molecular biology research on microbial pathogens and the needs of the poorest of the poor. After sequencing the complete genome of Leishmania donovani (a parasite causing one of the most important tropical diseases after malaria) in hundreds of clinical isolates, they identified a series of mutations specific of 'superparasites' and developed a simple assay that should allow tracking them anywhere.

IMDx HSV-1/2 for Abbott m2000 assay receives CE-marking

IntelligentMDx (IMDx) announced today that it has obtained CE-marking for its fourth automated, high-throughput molecular test designed and developed for the Abbott m2000 System.

Statistical method uses evolutionary information to enhance identification of disease-associated alleles

A book containing misprints may cause annoyance for the reader, but typos in an individual's genetic blueprint (DNA) can mean serious disease or even death. The search for genetic correlates for the wide range of diseases plaguing humankind has inspired a wealth of research falling under the heading of genome-wide association studies (GWAS).

Researchers uncover mechanism by which aging may weaken immune response

Researchers at Albert Einstein College of Medicine of Yeshiva University have uncovered one of the mechanisms by which aging may compromise the ability of the immune system to fight infections and respond to vaccines.

Courtagen launches nucSEEKPDx assay

Courtagen Life Sciences, Inc., a privately held life sciences company that provides innovative proteomic and genomic products and services to the life sciences industry, today announced the expansion of their genetic test menu. The new genetic test, nucSEEKPDx, will sequence approximately 1,100 nuclear genes constituting the mitochondrial exome, which encodes the vast majority of proteins found in the mitochondrion. This test is by far the most comprehensive test on the market for the management of mitochondrial disorders.

Researchers discover unknown mechanism that promotes growth and spread of cancer

Tiny vesicles released by tumors cells are taken up by healthy immune cells, causing the immune cells to discharge chemicals that foster cancer-cell growth and spread, according to a study by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) and at Children's Hospital in Los Angeles.

MiR-33 plays a key role in regulating bile metabolism

In research funded by the National Institutes of Health and the American Heart Association and published in EMBO Molecular Medicine, Saint Louis University investigator -ngel Bald-n, Ph.D., found that the microRNA miR-33 plays a key role in regulating bile metabolism. Further, the research suggests that, in an animal model, the manipulation of this microRNA can improve the liver toxicity that can be caused by statins.
