p53 Protein News and Research

RSS

The TP53 is a gene that instructs the cell to produce tumor protein (p53) ; a vital transcription factor and tumor suppressor. P53 is known as the “guardian of the genome” as it helps in regulating the cell cycle and acts as a tumor suppressor.

New pathway for inflammation-induced cancer

A well-known inflammatory protein spawns an enzyme that inactivates two tumor-suppressing genes, ultimately triggering production of new blood vessels to nourish breast cancer cells, researchers at The University of Texas M. D. Anderson Cancer Center report in the August edition of the journal Cell .

DNA repair by Brca2 prevents medulloblastoma

St. Jude investigators have gained some of the first major insights into how certain genes known to prevent cancer also guide the nervous system's normal development before birth and during infancy by repairing DNA damage.

Nanoparticle-enabled peptide delivery triggers tumor regression

Cells possess a variety of ways of dealing with mutations that can cause them to grow uncontrollably and eventually form a tumor. The tumor suppressor gene p53 plays a critical role in these cancer prevention processes, largely by triggering a form a cell death known as apoptosis.

miRNAs shown to be a critical force behind the anti-proliferation potential of p53

Cold Spring Harbor Laboratory (CSHL) researchers led by Lin He, Xingyue He, and Professor and Howard Hughes Medical Investigator (HHMI) Greg Hannon have identified a family of micro RNAs (miRNAs) that enable a critical tumor suppressor network, called the p53 pathway, to fight cancer growth.
