The arrest occurs from within G1, excluding contributions ... molecules to centrosomes (p53) in response to centrosome protein depletion is consistent with a role for centrosomes in the cell ...

We previously reported that the p53 tumor suppressor protein plays an essential role in the induction of tetraploid G1 arrest in response to perturbation of the actin cytoskeleton, termed actin ...

The p53 gene is extremely important in cell biology as its role is to regulate the cell cycle and halt the formation of tumors, leading to its nickname the “tumor suppressor gene.” However ...

The gene p53 ... role or roles of p53 in pluripotent stem cells is essential," he said. "Our goal was to finally resolve this question of whether p53 is essential for inducing cell cycle arrest ...

Researchers in the lab of Michael Sigal at the Max Delbrück Center and Charité – Universitätsmedizin Berlin have elucidated the role of the p53 gene in ulcerative colitis. The study ...
