Potential new COPD drug

A study led by researchers at Boston University School of Medicine (BUSM) has shown that a compound used in some skin creams may halt the progression of emphysema and reverse some of the damage caused by the disease. When the compound Gly-His-Lys (GHK) was applied to lung cells from patients with emphysema, normal gene activity in altered cells was restored and damaged aspects of cellular function were repaired.

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.

GlcNAc plays a key role in keeping cancerous monsters ‘fed’

Behaving something like ravenous monsters, tumors need plentiful supplies of cellular building blocks such as amino acids and nucleotides in order to keep growing at a rapid pace and survive under harsh conditions. How such tumors meet these burgeoning demands has not been fully understood.

Catechins may help reduce neurological complications linked to HIV

Current drug therapy for patients with HIV is unable to control the complete replication of the virus in the brain. The drugs therefore do not have any effect against the complications associated with neurocognitive impairment in patients with HIV. New research by Joseph Steiner and colleagues from Johns Hopkins University has discovered that a group of plant polyphenols known as catechins, which naturally occur in green tea and the seed of the cacao tree, may help in the prevention of these neurological complications.

Research focuses on evolution of sex and gamete function

The propagation of every animal on the planet is the result of sexual activity between males and females of a given species. But how did things get this way? Why two sexes instead of one? Why are sperm necessary for reproduction and how did they evolve? These as-yet-unresolved issues fascinate Timothy Karr, a developmental geneticist and evolutionary biologist at Arizona State University's Biodesign Institute.

Study reports new potential NOX inhibitor therapy for liver fibrosis

A study published in the online journal Hepatology reports a potential new NADPH oxidase (NOX) inhibitor therapy for liver fibrosis, a scarring process associated with chronic liver disease that can lead to loss of liver function.

NIH grants aim at creating 3-D tissue chips to help identify drug safety signals

Seventeen National Institutes of Health grants are aimed at creating 3-D chips with living cells and tissues that accurately model the structure and function of human organs such as the lung, liver and heart. Once developed, these tissue chips will be tested with compounds known to be safe or toxic in humans to help identify the most reliable drug safety signals - ultimately advancing research to help predict the safety of potential drugs in a faster, more cost-effective way.

Scientists identify inhibitors of key enzyme involved in survival of malaria parasite

An international team of scientists, led by researchers from the Department of Pediatrics at the University of California, San Diego School of Medicine, have identified the first reported inhibitors of a key enzyme involved in survival of the parasite responsible for malaria. Their findings, which may provide the basis for anti-malarial drug development, are currently published in the online version of the Journal of Medicinal Chemistry.

Research explains why exercise is beneficial for heart function in type 2 diabetes

A detailed study of heart muscle function in mice has uncovered evidence to explain why exercise is beneficial for heart function in type 2 diabetes. The research team, led by scientists at the Johns Hopkins University School of Medicine, found that greater amounts of fatty acids used by the heart during stressful conditions like exercise can counteract the detrimental effects of excess glucose and improve the diabetic heart's pumping ability in several ways.
