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.

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).

SLU professor to study how antithrombin might prevent premature death from heart disease

Alireza "Ray" Rezaie, Ph.D., professor of biochemistry and molecular biology at Saint Louis University School of Medicine, has received a $1.52 million NIH grant to study how the key blood clotting inhibitor antithrombin might be exploited to prevent premature death from heart disease.

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.

HIV and AIDS treatment: An interview with Charles Flexner, MD

The best estimates at the moment reckon that there are about 25 million people infected with HIV. Most of those are in resource-limited settings, including sub-Saharan Africa, South East Asia and India.

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.

Lipid ceramide helps cells keep cilium or antenna from retracting

A lipid that helps lotion soften the skin also helps cells find and stay in the right location in the body by ensuring they keep their "antennae" up, scientists report.

EGF helps prevent inflammation-induced cancer

Epidermal growth factor (EGF) is a protein that normally regulates intestinal healing. However, biological therapies, like EGF, also may pose the risk of increasing the possibility of cancer. Philip Dubé, PhD, and Brent Polk, MD, both of the Saban Research Institute of Children's Hospital Los Angeles have demonstrated that in preclinical models, EGF encourages healing and provides powerful anti-inflammatory properties that prevent inflammation-induced cancer.

BioView, ScreenCell enter collaboration agreement for imaging of CTC

BioView Ltd. and ScreenCell, a privately-held company, today jointly announced the signing of a commercial collaboration agreement for Bioview's Automated Cell Imaging Systems for imaging of CTC's isolated with ScreenCell's Cyto Kit.

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

MiR-125b downregulated in both aggressive and indolent forms of CLL

Loss of a particular microRNA in chronic lymphocytic leukemia shuts down normal cell metabolism and turns up alternative mechanisms that enable cancer cells to produce the energy and build the molecules they need to proliferate and invade neighboring tissue.

Cells close to death from toxin exposure can survive when toxins are removed

The vast majority of cells that appear to be on a one-way track to death after exposure to toxins can bounce back completely after those toxins are removed, Johns Hopkins scientists report in a new study. The finding, published in the June 15 issue of Molecular Biology of the Cell, is not only a testament to the indomitable cellular spirit, but could also offer some practical insight on how to save dying tissues after heart attacks or strokes as well as prevent cancer in cells transiently exposed to toxins.

Changing tissue landscape promotes higher cancer rates in the elderly

Cancers are age-related, much more frequent in the old than in the young. A University of Colorado Cancer Center review published today in the journal Oncogene argues against the conventional wisdom that the accumulation of cancer-causing mutations leads to more cancer in older people, instead positing that it is the changing features of tissue in old age that promote higher cancer rates in the elderly.

Abnormal bone marrow stem cells drive development of myelodysplastic syndromes

Researchers at Albert Einstein College of Medicine of Yeshiva University have found that abnormal bone marrow stem cells drive the development of myelodysplastic syndromes (MDS), serious blood diseases that are common among the elderly and that can progress to acute leukemia. The findings could lead to targeted therapies against MDS and prevent MDS-related cancers. The study is published today in the online edition of the journal Blood.
