Proteins are complex molecules that are made up of amino acids. They can be found in every cell in the body, and carry out vital processes that keep human beings alive. Mutations in proteins can lead to a multitude of diseases, the most common being cancer.

New method helps study interactions needed for formation of lipopolysaccharides

Scientists have combined chemistry and biology research techniques to explain how certain bacteria grow structures on their surfaces that allow them to simultaneously cause illness and protect themselves from the body's defenses.

Chokeberry extract reduces weight gain in insulin-resistant animals

Chokeberry bushes have for centuries been residents of eastern deciduous forests where their bright red and dark purple fruits continue to be favorite snacks of local bird species. Native Americans have also traditionally eaten dried chokeberries and prepared teas from parts of the plant, and several domesticated varieties now grace contemporary lawns and gardens from coast to coast.

Genes that predispose to smoking behavior and lung cancer identified: More reason to quit say researchers

According to new research there are certain genes in a smoker that make it difficult for them to cut down or quit the bad habit. This report from three studies published in the journal Nature Genetics mentions at least three different genetic mutations on chromosome 15 or changes that can increase the number of cigarettes smoked per day by an individual.

1976 "swine flu" vaccine protects against 2009 pandemic H1N1 influenza virus

New evidence shows immunization against "swine flu" in 1976 might provide individuals with some protection against the 2009 pandemic H1N1 influenza virus, according to new research from St. Jude investigators.

Temperature-sensing ability in proteins remain a mystery

Scientists at The Scripps Research Institute and the Genomics Institute of the Novartis Research Foundation (GNF) have shed new light on the molecular mechanism that enables us to sense temperature, such as the heat from a sizzling stove. In addition to contributing to our knowledge of basic biology, the findings could one day lead to new therapies for conditions such as acute or chronic inflammatory pain.

Mechanisms pathogenic viruses exploit to evade immune systems of hosts

Viruses have evolved a broad range of strategies that enable them to evade the immune systems of their hosts. A team of researchers led by LMU virologist Professor J-rgen Haas has been studying a novel, recently discovered mechanism that pathogenic viruses exploit for this purpose, and their latest results could point the way to new antiviral therapies. The mechanism is based on the production of short RNA molecules, called microRNAs, by the virus.

Young gymnasts need proper amount of nutrition to keep their bodies healthy: HSS

Most elite gymnasts reach their peak at age 15 or 16, training 20 to 36 hours per week when a body's calorie needs are at its highest. But in a sport where aesthetics can influence scores, some athletes adopt restrictive eating habits to control their physique.

Environmental factors may play bigger role in tumor development: BIDMC study

It is an accepted fact that genetics play a key role in a person's susceptibility to cancer, and that throughout life, mutations can cause damage to tumor suppressor genes further increasing the chances of developing cancerous tumors.

Johns Hopkins scientist receives AACR Award for Outstanding Achievement in Cancer Research

Joshua T. Mendell, M.D., Ph.D., an associate professor in the McKusick-Nathans Institute of Genetic Medicine at the Johns Hopkins University School of Medicine, and a Howard Hughes Medical Institute Early Career Scientist, is the recipient of the 30th annual American Association for Cancer Research Award for Outstanding Achievement in Cancer Research.

Researchers discover and characterize general mechanism controlling transcription elongation in bacteria

Researchers from NYU Langone Medical Center have discovered and characterized a general mechanism that controls transcription elongation in bacteria. The mechanism, described in the April 23 issue of Science, relies on physical cooperation between a moving ribosome and RNA polymerase (RNAP) that allows for a precise adjustment of the transcriptional yield in response to translational needs. The study could lead to the development of new ways to interfere with bacterial gene expression and serve as a new target for antimicrobial therapy.

GIS scientists' zebrafish model may aid drug development for PD

Scientists at the Genome Institute of Singapore, a biomedical research institute of the Agency for Science, Technology and Research, have recently developed a zebrafish model for Parkinson's disease that can be used for understanding the mechanism underlying its development. The knowledge gained will be helpful for future screening of new drugs to treat Parkinson's disease.
