Abstract The progression of the cell cycle is regulated by expression specific genes and fluctuations in cellular metabolic states. Previous research has employed cycle-based transcriptomics, proteomics, metabolomics analyses to identify cycle-dependent changes at gene expression, protein, levels.

The transcription factor p53 (encoded by TP53 ) plays diverse roles in human development and disease. While best known for its role tumor suppression, signaling also influences mammalian triggering cell fate decisions response to a wide variety of stresses. After over 4 decades study, new pathway that triggers activation mitotic delays was recently identified. Termed the surveillance or stopwatch pathway, USP28 53BP1 proteins activate delayed progression control promote genomic stability. In this Minireview, I discuss identification, potential neurodevelopmental disorders cancer, as well explore outstanding questions about function, regulation use biomarker anti-mitotic therapies.

ABSTRACT Cardiovascular diseases (CVDs) are the leading causes of death worldwide, with approx. Twenty million deaths in 2021. implants among most used biomaterials clinical world. However, poor endothelialisation and rapid thrombosis remains a challenge. Simple chemical surface modification techniques can be to steer biological interactions without affecting bioimplants' overall bulk characteristics such as radiopacity flexibility. Although silanes well studied for protein cell interactions, methodical investigation cardiac endothelial (EC) alongside smooth muscle (SMC) mimic natural arterial environments has been limited. In this study, these cells have investigated on surfaces functionalized methyl, amine, thiol, methacrylate, fluorine organosilane groups. Cardiac EC SMC growth was metabolic activity, time lapse imaging, immunofluorescent staining techniques. The results demonstrated that tested able selectively regulate viability cells. Aminosilane modified displayed 2‐fold higher activity HUVEC less HCASMC lines, compared tissue culture plastic controls. amino‐modification outperformed all other chemistries terms ability promote proliferation ECs, while importantly reducing SMCs. This report demonstrates aminosilane potential utilized novel cardiovascular implants, which could improve integration short possibly longer‐term. findings study suggest specific modifications enhance minimizing cells, often associated thrombosis. highlights carefully engineered outcomes implants.
