US baby boomers are fueling a wave of joint replacement surgeries, hoping to use new artificial knees and hips to stay active as they get older.
Inflammatory cues modulate goblet cell products important for intestinal barrier function
In a paper published in the December 2011 issue of Experimental Biology and Medicine, a team of scientists at the University of Illinois, Urbana-Champaign led by Rex Gaskins, PhD have demonstrated that both microbial and host inflammatory factors modulate sulfomucin production in a human cell line, LS174T, that models intestinal goblet cells.
BGI reports study results on frequent mutation of genes encoding UMPP components in kidney cancer
BGI, the world's largest genomics organization, announced that a study on frequent mutation of genes encoding ubiquitin-mediated proteolysis pathway (UMPP) components in clear cell renal cell carcinoma (ccRCC) is published online today in Nature Genetics. In addition to BGI, co-leaders of the study included Peking University Shenzhen Hospital, Shenzhen Second People's Hospital, among others. The study reveals that alteration of UMPP may contribute to ccRCC by activation of the hypoxia regulatory network, providing new clues to trace the key molecular mechanisms and pathways that underlie the tumorigenesis and progression of ccRCC.
Rabid bats kill at least eight children in Ecuador
At least eight children in Ecuador's Amazon basin region have died after being bitten by rabid bats, officials said Saturday.
Study identifies mechanisms cells use to remove bits of RNA from DNA strands
When RNA component units called ribonucleotides become embedded in genomic DNA, which contains the complete genetic data for an organism, they can cause problems for cells. It is known that ribonucleotides in DNA can potentially distort the DNA double helix, resulting in genomic instability and altered DNA metabolism, but not much is known about the fate of these ribonucleotides.
New gene study of ADHD points to defects in brain signaling pathways
Pediatric researchers analyzing genetic influences in attention-deficit/hyperactivity disorder (ADHD) have found alterations in specific genes involved in important brain signaling pathways. The study raises the possibility that drugs acting on those pathways might offer a new treatment option for patients with ADHD who have those gene variants—potentially, half a million U.S. children.
Discovery of a new reprogramming mechanism for tumor cells
Barcelona, 1st December, 2011.- A study by researchers Raúl Méndez, ICREA Research Professor at the Institute for Research in Biomedicine (IRB Barcelona) and Pilar Navarro at the IMIM (Institut de Recerca Hospital del Mar, Barcelona) describes a new reprogramming mechanism for the expression of genes responsible for turning a healthy cell into a tumor cell. In the study, published in this week's edition of Nature Medicine, the scientists have identified the protein CPEB4 as a "cellular orchestra conductor" that "activates" hundreds of genes associated with tumor growth.
