Webb12 apr. 2024 · The p53 gene is perhaps the most-studied, master tumor suppressor gene in cancer biology. When it works well, it’s difficult for tumors to develop. But in half of all tumors, mutated p53 has been shut down by repressors. Despite decades of research into restoring normal therapeutically-capable p53 activity, reliable strategies have … Webb14 aug. 2024 · INTRODUCTION. The TP53 gene encoding the tumor suppressor p53 is the most frequently mutated gene in human cancers (1, 2). p53 is also deactivated or …

Glutaminase 2, a novel p53 target gene regulating energy metabolism and antioxidant function[J]. Proc Natl Acad Sci U S A, 2010, 107(16): 7455-7460. DOI: ... WebbExplanation: In normal cells, p53 functions as a "guardian of the genome" by monitoring DNA damage and promoting either DNA repair or apoptosis (programmed cell death) depending on the severity of the damage. The functions of p53 are tightly regulated, and its activation or inactivation is critical for normal cell cycle progression.
WebbLoss of function mutations in tumor suppressor genes has been identified in many types of cancers, including ovarian, lung, colorectal, head and neck, pancreatic, uterine, breast, and bladder cancer 1). Examples of tumor suppressor genes include BRCA1, BRCA2, and p53 or TP53. A tumor suppressor gene is like the brake pedal on a car.
