Latest P53 Stories

Temptations to exceed the speed limit are always plentiful, but only reckless drivers give in to such impulses. Likewise, numerous growth factors always abound in our bodies, but only cancerous cells are quickly "tempted" by these chemicals to divide again and again. Healthy cells, in contrast, divide only after being exposed to growth factors for eight continuous hours. What happens during these eight hours in a healthy cell that resists the call to divide? And even more important, what...

IDIBELL researchers at UB have tested this molecule antagonist of MDM2, a protein active in brain tumorsResearchers 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...

BEVERLY, Mass., April 11, 2011 /PRNewswire/ -- Cellceutix Corporation (OTCQB: CTIX), a biopharmaceutical company focused on discovering and developing small molecule drugs to treat severe medical conditions including drug-resistant cancers, is pleased to announce that their recent poster at the 102nd Annual Meeting of the American Association for Cancer Research (AACR) generated significant interest from major Pharmaceutical companies and numerous investigators. The poster, entitled,...

Small-molecule MDM2 inhibitors developed at U-M show promise in multiple cancer typesA 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...

Experts from The Cancer Institute at NYU Langone Medical Center presented new research findings at the American Association for Cancer Research 102nd Annual Meeting 2011 held April 2-6, 2011 in Orlando, Florida. NYU Cancer Institute researchers discussed various breakthroughs such as a novel test for early-stage asbestos-related pulmonary cancer, a promising treatment strategy for glioblastomas, genome-wide mapping of nickel-related cancer and greater understanding of melanoma and bladder...

New findings by Fox Chase Cancer Center researchers link a common variant of the powerful anticancer gene p53 to increased inflammatory responses following DNA damage. The results may help explain why African Americans, who more frequently possess this variant, tend to be more susceptible to certain kinds of inflammation-related diseases and cancers, such as type II diabetes and colorectal cancer.Maureen Murphy, PhD, associate professor at Fox Chase, published the findings in the March issue...

When cells find themselves in a tight spot, the cell cycle regulator p21 halts the cell cycle, buying cells time to repair the damage, or if all else fails, to initiate programmed cell death. In contrast to other stress-induced genes, which dispense with the regular transcriptional entourage, p21Cip1 still requires SKIP, a transcription elongation factor that also helps with the editing of transcripts, to be expressed, found researchers at the Salk Institute for Biological Studies.In the...

Ulcerative colitis (UC) is an inflammatory bowel disease thought to be related to aberrant activation of the immune system in the intestine. Recent research has also suggested that regulated cell death (apoptosis) of the intestinal epithelial cells is a contributing factor to the pathogenesis. However, the molecular mechanisms that control the cellular response to inflammation are incompletely understood.In this paper, Lin Zhang, at the University of Pittsburgh, in Pennsylvania, found that in...

Researchers offer the first evidence that DNA damage can lead to the regulation of inflammatory responses, the body's reaction to injury. The proteins involved in the regulation help protect the body from infection.The study, performed by scientists at the National Institute of Environmental Health Sciences (NIEHS), which is part of the National Institutes of Health, is one of the first studies to come out of the recently established NIEHS Clinical Research Unit (CRU)...

(Ivanhoe Newswire) -- Researchers have identified a new therapeutic target for lung cancer. A variant of the protein AIMP2 is highly expressed in lung cancer cells.Lung cancer is one of the most common cancers in the world and is a leading cause of death from cancer. Despite treatment options such as surgery, radiation and drugs, the survival rate for patients with lung cancer has not improved much over the past few decades.Previously, researchers found the protein AIMP2 acted as a...
