Scratch no more: Gene for itch sensation discovered

...ional itch receptors," Chen says. "We know of some proteins that are similar to GRPR, so now we're trying to determine if there is functional redundancy in the itching pathway." GRPR knockout mice had normal reactions to painful stimuli, indicating that pain and itch are mediated by separate sets of genes in...

Common cancer gene sends death order to tiny killer

Josh Mendell, M.D., Ph.D., an assistant professor in the McKusick-Nathans Institute of Genetic Medicine, suspected that p53 activates microRNAs like miR-34a because a number of studies have demonstrated that these tiny RNA molecu...

Research identifies protein that signals flowering in squash plants

... with the photoperiodic induction of flowering are proteins known as CONSTANS (CO) and FLOWERING LOCUS T (FT). CO does not appear to travel long distances through the phloem, but rather, it strongly influences the production of another substance (i.e. florigen) that does. Recent work in a number of laboratori...

Cells re-energize to come back from the brink of death

...cells that become cancerous lack caspase and other proteins needed to support apoptosis after MOMP releases cytochrome c. But this victory over death is short-lived if CICD is activated. However, some cancerous cells not only dodge death from apoptosis by eliminating caspase activation, but they also foil CID...

"Still, knowing the pH values can help pharmacologists and chemists redesign a molecule to take advantage of these changes."...

Loss of stem cells correlates with premature aging in animal study

...e body’s response to damaged DNA, and mutations in proteins in the DNA damage response underlie certain types of cancer and other disorders in humans. This work appears in the inaugural issue of Cell Stem Cell. “The reason we’re seeing the early signs of aging in these mice is that we’re exhausting their a...

Study shows big power of small RNAs, not just proteins, in halting cancer

...in surrounding healthy cells. Most suspected that proteins would be revealed as key to the power of p53, but this latest research published June 6 by Nature now identifies miRNAs as a critical force behind the anti-proliferation potential of p53.

Research shows cord blood comparable to matched bone marrow

.... Human Leukocyte Antigens (HLA) are a group of proteins on bone marrow cells that can provoke the immune system to respond. When doing bone marrow or cord blood transplants, doctors generally try to have the donors’ and recipients’ HLA types match as closely as possible. Wagner added that increasing the...
