In the first study, the authors describe a novel p53 target gene, Ptprv, which plays a key role in mediating G1 cell cycle arrest after DNA damage. Ptprv is transcriptionally activated by p53 and is essential for proper checkpoint control, as its loss disrupts G1 arrest without compromising p53‐dependent apoptosis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "\n \nDis primis duis mauris potenti non at sociosqu ultricies massa.
