Researchers On The Path To Building Bone

... fewer cells die due to apoptosis. Pten is a tumor suppressor gene that applies a break on the main cell survival pathway, causing cells to die,” said Thomas L. Clemens, Ph.D., professor of pathology and director of the UAB Division of Molecular and Cellular Pathology. “We devised a way to remove the Pten break...

Genetic Pathways to Curable and Incurable Forms of Pancreatic Cancer Identified

...n early mutation of Dcp4, in which one copy of the suppressor gene is eliminated, lead to cancer by a different path, beginning with the creation of a distinct class of precancerous lesions in the ductal epithelium called mucinous cystic neoplasms (MCN). This initiates a process that results in the rarer but fa...

Blood DNA Predicts Liver Cancer Early

... The scientists examined changes in certain tumour suppressor genes that have been associated with the development of liver carcinomas. The researchers studied the blood of patients enrolled in a cancer-screening programme in Taiwan who provided repeated blood samples prior to diagnosis. A total of 12,000 mal...

Head and Neck Cancer Vaccine Targets Proteins to Create Immune Response

... researchers created the vaccine to target a tumor suppressor gene called p53, which is mutated in most cancers and associated with poor clinical outcomes. Previous research has determined that mutated p53 also expresses unaltered, or "wild-type," p53 peptides in tumors. When presented on dendritic cells, these...

Researchers Have Identified Subgroup Sensitive to the Drug Cisplatin

...ast development and is related to the common tumor suppressor p53. They analyzed tissue samples from triple-negative breast tumors and normal breast tissues for the expression of several forms of p63 and another related protein called p73, known to promote the cell-death process called apoptosis. The researc...

Cytokine Resistance Contributes to Pathology of Type 2 Diabetes

...ice caused chronic over-expression of an important suppressor of cytokine signalling (SOCS) protein, which aborts the cascade of events that normally leads to insulin uptake and/or cytokine signalling in a balanced inflammatory response. According to Freund, the study supports earlier findings that inflammati...

Afro- American Women Have More Aggressive Breast Cancer

...igh cell turnover and propensity for p53, a tumour suppressor gene, to be abnormal, in addition to these 'triple negative' features in the African American tumours, making them more aggressive and more likely to metastasize," Dr. Morris says. "These are preliminary data that enable us to plan how we want to pur...

Role of MicroRNA in Cancer Suppression Identified

...ath (apoptosis) in the context of the potent tumor suppressor p53. p53 has been widely accepted as a powerful tumor inhibitor that can prevent or slow the spread of cancer cells by facilitating apoptosis. In this study, activation of p53 in-vivo in mice as well as in cultured human cells induced the expressio...

Skin Cancer can Be Triggered by P53 Mutation

...in the USA each year. Mutations in the p53 tumor suppressor gene have been implicated in tumor formation: some give rise to a loss-of-function whereas the majority of mutations result in a gain-of-function. In the first of these two studies, Dennis Roop, Carlos Caulin, and colleagues from Baylor College of ...
