Yale researchers have discovered how the "guardian of the genome'' oversees quality control in the production of sperm – and perhaps in many other cells as well. The research published online Feb. 16 in the journal Current Biology opens up the potential of developing new forms of birth control and fertility treatment – and even new ways to combat many forms of cancer. Sperm and other cells go through a sort of inspection process triggered by a key regulatory gene, p53, which...

The expression of p53 and Mdm2 is closely related. In an article published this week in the Cancel Cell review, Robin Fahraeus and his collaborators from Inserm Unit 940 ("Therapeutic Targets for Cancer"), demonstrate that cellular response to DNA damage requires involvement from the protein kinase ATM so that Mdm2 can positively or negatively control protein p53. Much focus is placed on protein p53 in cancer research. Discovered in 1979, p53 precisely regulates cell proliferation and...

Discovery generates potential for new anti-cancer therapies Researchers at the University of Southern California have identified two molecules that may be more effective cancer killers than are currently available on the market. The peptides, molecules derived from a cancer-causing virus, target an enzyme in cancerous cells that regulates a widely researched tumor suppressor protein known as p53. The peptides inhibit the enzyme, causing p53 levels in cancer cells to rise, which leads to...

A protein that appears to play a key role in the formation of lymphoma and other tumors by inhibiting a tumor-suppressing gene has been identified by a team of veterinary and human medicine researchers at the University of California, Davis. The researchers suggest that the newly identified protein may be a potential target for diagnosing and treating lymphoma in humans and animals. They will report their findings July 15 in the journal Genes & Development. "Results from this study...

(Ivanhoe Newswire) "“ According to the Leukemia and Lymphoma Society, over 21,000 Americans died from lymphoma cancer last year. Lymphoma refers to a group of blood cancers that start in the lymphatic system, a network of lymph vessels and lymph nodes that play a vital role in the body's immune system. Researchers believe that a newly identified protein may be a potential target for diagnosing and treating lymphoma in humans and animals. The protein appears to play a key role in the...

Salk Institute scientists show how regulation of a key damage response protein can make the difference between survival and death after radiation Scientists at the Salk Institute for Biological Studies have found clues to the functioning of an important damage response protein in cells. The protein, p53, can cause cells to stop dividing or even to commit suicide when they show signs of DNA damage, and it is responsible for much of the tissue destruction that follows exposure to ionizing...

IDIBELL researchers at UB have tested this molecule antagonist of MDM2, a protein active in brain tumors Researchers of Apoptosis and Cancer Group of the Bellvitge Biomedical Research Institute (IDIBELL) have found that a small molecule, Nutlin-3a, an antagonist of MDM2 protein, stimulates the signalling pathway of another protein, p53. By this way, it induces cell death and senescence (loss of proliferative capacity) in brain cancer, a fact that slows its growth. These results open the door...

Small-molecule MDM2 inhibitors developed at U-M show promise in multiple cancer types A study led by researchers at the University of Michigan Comprehensive Cancer Center showed in animal studies that new cancer drug compounds they developed shrank tumors, with few side effects. The study, done in two mouse models of human cancer, looked at two compounds designed to activate a protein that kills cancer cells. The protein, p53, is inactivated in a significant number of human cancers. In some...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
