Antibody-guided drug shows encouraging activity in metastatic breast cancer (December 26, 2009) -- A new antibody-drug compound shrank or halted the growth of metastatic breast tumors in almost half of a group of patients whose HER2-positive cancer had become resistant to standard therapies, according to early data. ... > full story
Bone control of glucose levels (December 26, 2009) -- Bone cells known as osteoblasts were recently shown to have a role in controlling the biochemical reactions that generate energy via secretion of the molecule osteocalcin. Researchers have now determined that the protein FoxO1 regulates this function of osteoblasts in mice. ... > full story
Who gets expensive cancer drugs? A tale of two nations (December 26, 2009) -- The well-worn notion that patients in the United States have unfettered access to the most expensive cancer drugs while the United Kingdom's nationalized health care system regularly denies access to some high-cost treatments needs rethinking, a team of bioethicists and health policy experts says in a new report. ... > full story
Growing evidence suggests progesterone should be considered a treatment option for traumatic brain injuries (December 25, 2009) -- Researchers recommend that progesterone, a naturally occurring hormone found in both males and females that can protect damaged cells in the central and peripheral nervous systems, be considered a viable treatment option for traumatic brain injuries. ... > full story
Cause of nonallergic itch identified (December 25, 2009) -- Scratching below the surface of a troublesome sensation that's equal parts tingle-tickle-prickle, sensory scientists have discovered in mice a molecular basis for nonallergic itch. ... > full story
Sensitizing leukemic cells to death-inducing compounds (December 25, 2009) -- Recent research has indicated that in the process of generating energy, leukemic cells use a cellular pathway known as fatty acid oxidation, rather than pyruvate oxidation, as had been previously thought. A team of researchers has now used this knowledge to develop a way to sensitize human leukemic cells to molecules that induce cell death by a process known as apoptosis. ... > full story
Novel gene found for childhood-onset asthma (December 25, 2009) -- Pediatric researchers have identified a novel gene involved in childhood asthma, in one of the largest gene studies to date of the common respiratory disease. Because the gene, called DENND1B, affects cells and signaling molecules thought to be instrumental in the immune system overreaction that occurs in asthma, the discovery may have singled out an important target for new treatments. ... > full story
Chicago Cancer Genome Project studies genetics of 1,000 tumors (December 25, 2009) -- A Chicago research team is one year into a three-year project to collect and analyze the genetic sequence and variations of every gene expressed by 1,000 tumors with a long-term goal of translating genomic discoveries into diagnostic tools and therapeutic strategies. ... > full story
