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.

Structure of fibril protein could lead to specific targets for diagnosis, treatment of Parkinson's disease

Chemists have identified the complex chemical structure of the protein that stacks together to form fibrils in the brains of Parkinson's disease patients. Armed with this knowledge, researchers can identify specific targets for diagnosis and treatment. [More]
Research shows tumor suppressor protein regulates polarity genes

Research shows tumor suppressor protein regulates polarity genes

What does Brad Pitt have in common with a fruit fly? His Hollywood hairstyles cover a prominent cowlick - the swirl of hair that that is caused by a patterning mechanism also active in our two-winged friends -- that similarly feature "polarized" hair patterns. [More]
Extracellular vesicle isolation and characterization: an interview with Dr Carley Ross

Extracellular vesicle isolation and characterization: an interview with Dr Carley Ross

Extracellular vesicles are membrane surrounded structures released by cells in an evolutionally conserved manner. There are three main types of EVs, Exosomes (50-100 nm), Microparticles (200 nm-1 um) and Apoptotic bodies. [More]

Study provides better picture of molecular basis for antibiotic resistance

Scientists from the University of Leeds have solved a 25-year-old question about how a family of proteins allow bacteria to resist the effects of certain antibiotics. [More]

Shigella dysenteriae pathogen probably originated in Europe, genetic study reveals

The largest genetic study on the bacterium responsible for epidemic dysentery has revealed that the Shigella dysenteriae pathogen, which remains a real scourge in Africa and Asia, probably originated in Europe. [More]
Specialized gene editing system paves way to eventual cure for HIV patients

Specialized gene editing system paves way to eventual cure for HIV patients

A specialized gene editing system designed by scientists at the Lewis Katz School of Medicine at Temple University is paving the way to an eventual cure for patients infected with HIV, the virus that causes AIDS. [More]
Teach-to-goal inhaler education improves mastery of life-saving technique

Teach-to-goal inhaler education improves mastery of life-saving technique

A rescue inhaler can be a lifesaver during an asthma or COPD flareup, but using a rescue inhaler is complicated and misuse is common, putting patients' lives at risk. An education strategy, called teach-to-goal, may help patients use their inhalers properly during these critical times, according to research published online ahead of print in the American Thoracic Society journal Annals of the American Thoracic Society.

UCMR researchers discover compounds that can attenuate virulence of Listeria monocytogenes

UCMR researchers discover compounds that can attenuate virulence of Listeria monocytogenes

Scientists at Umea Centre for Microbial Research have discovered chemical compounds which are able to attenuate the virulence of the bacterial human pathogen Listeria monocytogenes. Their findings are published today in the high impact journal Cell Chemical Biology. [More]
UT Southwestern researchers identify new role for protein linked to neurological disorders and cancers

UT Southwestern researchers identify new role for protein linked to neurological disorders and cancers

Researchers at UT Southwestern Medical Center have identified a second role for a class of RNA-binding proteins, revealing new insights about neurological diseases and conditions associated with this protein such as autism, epilepsy, and certain types of cancer. [More]
Inhibiting cholesterol esterification can potentiate antitumor activity of killer T cells

Inhibiting cholesterol esterification can potentiate antitumor activity of killer T cells

As key players in the immune system, T cells provide tumor surveillance and have direct antitumor effects. However, tumors can escape T-cell attack through various mechanisms in the tumor microenvironment. Reactivating the antitumor effects of T cells has shown great clinical benefits in treating various cancers. [More]
Homeostasis may have allowed first living cells to maintain internal environment

Homeostasis may have allowed first living cells to maintain internal environment

A Massachusetts General Hospital research team investigating how the earliest stages of life might have developed has discovered a way the first living cells could have met a key challenge -- maintaining a constant internal environment, a process called homeostasis, even when external conditions change.

UCSF study marks important step toward finding cure for Ebola

UCSF study marks important step toward finding cure for Ebola

In experiments carried out partly at the Department of Energy's SLAC National Accelerator Laboratory, scientists have determined in atomic detail how a potential drug molecule fits into and blocks a channel in cell membranes that Ebola and related "filoviruses" need to infect victims' cells. [More]
Scientists find surprising link between iPS cell reprogramming, blood cell formation and cancer

Scientists find surprising link between iPS cell reprogramming, blood cell formation and cancer

The ability to reprogram cells has revolutionized stem cell research with major implications for almost all fields of modern biology. A decade ago Shinya Yamanaka described a procedure that revolutionized stem cell biology. Using a genetic trick that introduces a cocktail of four genes into cultured cells from human biopsies, he was able to generate induced pluripotent stem cells (iPS) from mature skin or blood cells [More]
Biological change in mosquito mating could be used to fight mosquito-borne diseases

Biological change in mosquito mating could be used to fight mosquito-borne diseases

Genetic cues from male Aedes aegypti mosquitoes passed on during sex affect which genes are turned on or off in a females' reproductive tract post-mating, including genes related to blood feeding, egg development and immune defense, according to new Cornell research. [More]

NIH-funded investigators develop therapeutic compound effective against malaria

An international team that includes NIH-funded researchers at Stanford University has developed a therapeutic compound that is effective in inhibiting Plasmodium falciparum, one of five species of parasite that infects people with malaria, and the strain which causes the highest number of malaria deaths.

TSRI researchers uncover new molecular mechanism underlying neurodegenerative diseases

A new study led by scientists at The Scripps Research Institute suggests that cells construct protein "clumps" to protect against neurodegenerative diseases such as amyotrophic lateral sclerosis, a.k.a. ALS or Lou Gehrig's disease. [More]

Novel nanoparticle technology can decipher protein structures and help access drug targets

Researchers at Karolinska Institutet, Sweden, have developed a nanoparticle technology that can be used to stabilise membrane proteins so that their structure can be studied in a lipid environment. The method, described in Nature Methods, makes it possible to access drug targets that previously could not be investigated and therefore potentially allows for the development of novel drugs, therapeutic antibodies and vaccines.
