Bmi1 and p53
WebPolycomb complex protein BMI-1 also known as polycomb group RING finger protein 4 (PCGF4) or RING finger protein 51 (RNF51) ... Bmi1 is also thought to inhibit ageing in neurons through the suppression of p53. The Bmi-1 protein interacts with several signaling pathways containing Wnt, Akt, Notch, Hedgehog and receptor tyrosine kinases (RTK). WebMar 10, 2024 · In addition, Korieh K et al. examined the protein levels of Ki-67, p53, and cyclin A and showed that there was a significant positive correlation between BMI1 and Ki-67, cyclin A or p53, implying that high BMI1 expression may be an independent prognostic marker for EC (Horie et al., 2024).
