Bioartificial kidney under study at MCG

...sis is given, it only replicates a fraction of the work of the kidneys, which are involved in diverse functions ranging from regulating vitamin D to modulating the immune response. "Existing forms of dialysis have only replaced the ability of the kidneys to rid the body of waste products and correct abnor...

Jump-starting T Cells In Skin Cancer

Molecular biology fills gaps in knowledge of bat evolution

...nd Biodiversity Research, Kent, U.K. "The present work advances our understanding of where bats originated, when they diversified and how different bat families are related to each other," Springer said. "It also quantifies the fraction of the fossil record that is missing for bats." The team, using DNA...

A new mechanism of regulating RNA degradation

...that many of the tools cells use to regulate genes work after transcription, by moderating the activity and the life span of the RNA itself. One major pathway for such post-transcriptional regulation is called nonsense-mediated decay (NMD). Originally NMD was thought to destroy incorrectly transcribed or...

Enzyme, lost in most mammals, is shown to protect against UV-induced skin cancer

...superior resistance to UV-induced skincancer. This work clearly points to CPD lesions as the majorintermediate in UV-induced cellular damage leading to non-melanoma skincancer. Importantly, it also suggests that photolyases may besuccessfully employed as a genetic tool to combat UV-induced skincancer....

Yellowstone microbes fueled by hydrogen, according to U. of Colorado study

New, automated tool successfully classifies and relates proteins in unprecedented way

...machine learning, andbiomedical engineering. "This work should provide a more thoroughunderstanding of cellular processes that underlie disease."Using this approach to spot a protein cluster could help scientistsidentify a common protein structure that enables those proteins togather in one part of the ce...

New binding target for oncogenic viral protein

...iral replication and tumorigenesis. "I think this work underlines the importance of Fbw7 as an emerging tumor suppressor and the consequences of its loss in tumors," Dr. Welcker emphasized. "The study of DNA tumors viruses has been an extremely important tool in understanding the cellular pathways that ...

There are many accounts of termites not consuming a piece of palatable wood." ### Listen to termites walking and chewing pine http://www.csiro.au/audio/termite_Feb05.mp3 Termite pictures: http:...

Elusive HIV shape change revealed; Key clue to how virus infects cells

...new findings may help pin down how these compounds work and hasten their development into drugs. "The findings also will help us understand why it's so hard to make an HIV vaccine, and will help us start strategizing about new approaches to vaccine development." The studies, performed in the Children's H...

Genome of deadly amoeba shows surprising complexity, evidence of lateral gene transfer

Researchers Uncover Key Step In Manufacture of Memory Protein

...ular Neurobiology. The researchers published their work in the January 20 issue of Neuron. Specifically, the researchers discovered that the enzyme carboxypeptidase E, (CPE) is needed to deliver the early, or inactive, form of BDNF ?proBDNF ?to a special compartment in the neuron (nerve cell.) Once in th...
