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.

Scientists create mathematical model that helps to design new drug cocktails against HIV

For years, doctors treating those with HIV have recognized a relationship between how faithfully patients take the drugs they prescribe, and how likely the virus is to develop drug resistance. More recently, research has shown that the relationship between adherence to a drug regimen and resistance is different for each of the drugs that make up the "cocktail" used to control the disease.

Study explains why some cancer vaccines are not as effective as hoped

A research report published in the September 2012 issue of the Journal of Leukocyte Biology offers a possible explanation of why some cancer vaccines are not as effective as hoped, while at the same time identifies a new therapeutic strategy for treating autoimmune problems. In the report, scientists suggest that cancer, even in the very early stages, produces a negative immune response from dendritic cells, which prevent lymphocytes from working against the disease.

Glaucoma and cell death: an interview with Dr. Vivek Gupta

Glaucoma is normally caused by increased pressure of aqueous humour fluid in the eye. A defining feature of this disease is destruction of a particular type of cells in the retina called retinal ganglion cells and excavation of the optic disc region.

DNA synthesis in the 3’ and 5’ direction possible using new template-directed method

When a cell divides, it passes on genetic information by producing copies of its DNA. Chemists have also learned to copy DNA. In the journal Angewandte Chemie, a German team has now introduced a new copying technique that uses a single strand of DNA as the “master copy”, like a cell, but does not require enzymes.

Study shows molecular mechanism behind type 3c pancreatic diabetes

Mice develop pancreatic diabetes (type 3c) when they lack certain genes in the E2F group, and to understand how this happens, Olatz Zenarruzabeitia has focussed on the molecular mechanism behind it.

Oxford University Press announces acquisition of American Journal of Hypertension

Oxford University Press (OUP) today announced that the esteemed American Journal of Hypertension will be joining the publisher's journal collection.

Cholera toxin binds differently to intestinal cells than previously thought

The likelihood of becoming seriously ill from cholera depends on your blood group. It is possible to find a new remedy for the feared illness by studying the molecular structure in the toxin in the cholera bacteria.

New molecular mechanism plays a crucial role in inhibiting TGF-beta signaling

Researchers headed by Maria Macias an ICREA researcher at the Institute for Research in Biomedicine (IRB Barcelona) and Joan Massagu-, a Howard Hughes Medical Institute investigator at Memorial Sloan-Kettering Cancer Center (MSKCC) in New York, have identified a new molecular mechanism that plays a crucial role in the control of the activation of certain genes associated with cancer.

Study demonstrates how DBP production is modulated by daily variations of temperature

Numerous processes in our body fluctuate in a regular pattern during the day. These circadian (or daily) variations can be driven by local oscillators present within our cells or by systemic signals controlled by the master pacemaker, located in the brain. Ueli Schibler, professor at the University of Geneva (UNIGE), Switzerland, unveils a molecular mechanism by which body temperature rhythms influence the expression of 'clock genes' and synchronize local oscillators.

Parental methylated histones not transferred to daughter DNA

It's widely accepted that molecular mechanisms mediating epigenetics include DNA methylation and histone modifications, but a team from Thomas Jefferson University has evidence to the contrary regarding the role of histone modifications.

PHF20 transcriptional factor plays a unique role in regulating p53

Researchers at Moffitt Cancer Center and colleagues have identified PHF20, a novel transcriptional factor, and clarified its role in maintaining the stability and transcription of p53, a gene that allows for both normal cell growth and tumor suppression. PHF20, the researchers found, plays a previously unknown and unique role in regulating p53.

Influenza virus can change microRNA expression to control immune responses in human lung cells

When you are hit with the flu, you know it immediately -- fever, chills, sore throat, aching muscles, fatigue. This is your body mounting an immune response to the invading virus. But less is known about what is happening on the molecular level.

Researcher describes structure and function of tuberculosis efflux pump regulator

Edward Yu took note of the facts - nearly 2 million deaths each year, 9 million infected each year, developments of multidrug-resistant, extensively drug-resistant and now totally drug-resistant strains - and decided to shift his research focus to tuberculosis.

Thiabendazole drug slows tumor growth and shows promise as chemotherapy for cancer

An inexpensive antifungal drug, thiabendazole, slows tumor growth and shows promise as a chemotherapy for cancer. Scientists in the College of Natural Sciences at The University of Texas at Austin made this discovery by exploiting the evolutionary relatedness of yeast, frogs, mice and humans.
