Human impact on health of soil, and impact of unhealthy soil on society are intertwined, says LSU researcher

It may sound counterintuitive, but LSU Associate Professor of Chemistry Robert Cook has made a career out of studying the ways organic materials found in the environment, including soils, can either get dirty or stay clean. In fact, the National Science Foundation, or NSF, was so impressed with his efforts that the funding institute awarded Cook one of its most prestigious awards - the NSF CAREER award.

Cigarette smoking affects entire networks of gene interaction: Research

The effects of smoking cigarettes on gene activity have been investigated in the largest study of its kind. Researchers writing in the open access journal BMC Medical Genomics studied white blood cells taken from 1,240 people to identify 323 unique genes whose expression levels were significantly correlated with smoking behavior.

Plexxikon announces promising preclinical data of PLX3397

Plexxikon Inc. today announced promising preclinical data from in vivo Alzheimer's Disease studies demonstrating a dramatic reduction in activated microglia in the brains of very old (22 months) 3xTG-AD mice, a triple transgenic model for Alzheimer's Disease. This reduction of activated microglia led to significantly improved learning in the treated group.

New use of green fluorescent protein

Scientists are reporting discovery of a way to help proteins such as the new generation of protein-based drugs -- sometimes heralded as tomorrow's potential "miracle cures" -- get past the biochemical "Entrance Forbidden" barrier that keeps them from entering cells and doing their work. The new technique, described in the monthly journal, ACS Chemical Biology, represents a new use for an engineered form of green fluorescent protein, the topic of the 2008 Nobel Prize in Chemistry that is one of the most important research tools in biosciences.

Implantable artificial salivary gland to be developed for Xerostomia patients

The goal of this research was to create an ECM modified hyaluronic acid (HA) based hydrogel culture system that allows for the growth and differentiation of salivary acinar cells into functional acini-like structures capable of secreting large amounts of protein and fluid unidirectionally. Xerostomia, a condition resulting from irradiation of the head and neck, affects more than 40,000 cancer patients each year in the United States. According to this research, these patients will greatly benefit from the development of a functional implantable artificial salivary gland.

Exposure to cigarette smoke can alter gene expression, study finds

In the largest study of its kind, researchers at the Southwest Foundation for Biomedical Research have found that exposure to cigarette smoke can alter gene expression -- the process by which a gene's information is converted into the structures and functions of a cell. These alterations in response to smoking appear to have a wide-ranging negative influence on the immune system, and a strong involvement in processes related to cancer, cell death and metabolism.

Biodel reports preclinical test results of BIOD620 glucose-regulated or "smart" basal insulin product candidate

Biodel Inc. today reported results of preclinical tests which demonstrated the potential of the company's glucose-regulated or "smart" basal insulin product candidate, BIOD620, to release insulin proportionally in response to changing glucose conditions. In an oral presentation today at the 37th Annual Meeting and Exposition of the Controlled Release Society in Portland, Oregon, Nandini Kashyap, director of novel drug delivery at Biodel, described results of in vitro and in vivo studies with diabetic pigs which compared the use of BIOD620 to Lantus® (insulin glargine).

GWAS suggests genetic variant with increased oncogene expression for cancer study

The study, published July 13th in Genome Research, showcases a new protocol for studying the activity of cancer-risk variants suggested by GWAS studies. The results also underscore the dramatic consequences of small genetic changes even in the vast stretches of DNA, known as "gene deserts," that do not code for proteins.

Female mice that lack fucose mutarotase gene exhibit male-like sexual behavior

The mammalian fucose mutarotase enzyme is known to be involved in incorporating the sugar fucose into protein. Female mice that lack the fucose mutarotase (FucM) gene refuse to let males mount them, and will attempt copulation with other female mice. Researchers writing in BioMed Central's open access journal BMC Genetics created the FucM mouse mutants in order to investigate the role of this enzyme in vivo.

Researchers report how mature red blood cells form

We take our blood for granted, but its creation requires a complicated series of steps, starting with the formation of blood stem cells during early embryonic development, followed by progressive differentiation into the progenitors of red cells, white cells and platelets, and ultimately the full set of blood cells.
