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.

SPR microscopy examines binding kinetics of membrane proteins

Proteins adorning the surfaces of human cells perform an array of essential functions, including cell signaling, communication and the transport of vital substances into and out of cells. They are critical targets for drug delivery and many proteins are now being identified as disease biomarkers - early warning beacons announcing the pre-symptomatic presence of cancers and other diseases.

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.

Pyruvate kinase M2 fuels tumor growth by influencing H3 histone protein

A metabolic protein that nourishes cancer cells also activates tumor-promoting genes by loosening part of the packaging that entwines DNA to make up chromosomes, a team led by scientists at The University of Texas MD Anderson Cancer Center reports in the Aug. 16 issue of Cell.

Rhomboid enzymes and malaria treatment: an interview with Sinisa Urban

Rhomboid enzymes live in the cell’s membrane where their job is to cut the anchors of proteins, which releases the target proteins from the membrane.

Pathway describes how alpha hydroxyl acids cause skin exfoliation

A team of investigators from UC Davis and Peking University have discovered a mechanism that may explain how alpha hydroxyl acids (AHAs) -- the key ingredient in cosmetic chemical peels and wrinkle-reducing creams -- work to enhance skin appearance. An understanding of the underlying process may lead to better cosmetic formulations as well as have medical applications.

Scientists develop new way to study role of GABA-A receptors in various disorders

A new way to study the role of a critical neurotransmitter in disorders such as epilepsy, anxiety, insomnia, depression, schizophrenia, and alcohol addiction has been developed by a group of scientists led by Gong Chen, an associate professor of biology at Penn State University.

Studies identify genetic mutations that play important roles in startle disease

Two studies published in the Journal of Biological Chemistry identify genetic mutations that play important roles in the condition commonly referred to as startle disease. Startle disease is characterized by an exaggerated response to noise and touch, which can interfere with breathing, cause catastrophic falls and even result in death.

Researchers discover genetic process that can restore function to a CF defective protein

Researchers at the University of Iowa Carver College of Medicine have discovered a genetic process that can restore function to a defective protein, which is the most common cause of cystic fibrosis (CF).

Scientists decode stability blueprint of rhomboid enzyme

Johns Hopkins scientists have decoded for the first time the "stability blueprint" of an enzyme that resides in a cell's membrane, mapping which parts of the enzyme are important for its shape and function.

Two new targets could enhance the body's defenses against West Nile and hepatitis C

Two new targets have been discovered for antiviral therapies and vaccines strategies that could enhance the body's defenses against such infectious diseases as West Nile and hepatitis C. The targets are within the infection warning system inside living cells.

A2bAR receptor plays a significant role in regulation of type 2 diabetes and obesity

A recent study led by Boston University School of Medicine (BUSM) demonstrates that the A2b-type adenosine receptor, A2bAR, plays a significant role in the regulation of high fat, high cholesterol diet-induced symptoms of type 2 diabetes.

New class of chemically produced antimicrobial agents could become future infection treatment alternative

The World Health Organization (WHO) has named antimicrobial resistance one of the most important threats to human health. We therefore need to find new compounds that can be used as future alternatives to conventional antibiotics.

Bryologs more potent than prostratin in treating HIV

Thanks to antiretrovirals, an AIDS diagnosis hasn't been a death sentence for nearly two decades. But highly active antiretroviral therapy, or HAART, is also not a cure.

Researchers verify role of alpha-synuclein aggregates in vivo

Using a two-photon microscope capable of peering deep within living tissue, researchers at the University of California, San Diego School of Medicine have found new evidence that alpha-synuclein protein build-up inside neurons causes them to not only become "leaky," but also to misfire due to calcium fluxes.

Oligomers may be responsible for onset of Alzheimer's

Alzheimer's disease is one of the most dreaded and debilitating illnesses one can develop. Currently, the disease afflicts 6.5 million Americans and the Alzheimer's Association projects it to increase to between 11 and 16 million, or 1 in 85 people, by 2050.
