DNMT3B methylates TP53. 5 / 5
| 5

reach
"In conclusion, our data strongly illuminates that ROS-PI3K and Akt pathway participates in the PM2.5-induced DNMT3B up-regulation, which leads to P53 promoter hypermethylation and down-regulation of P53 expression, a critical early event in epithelial cell carcinogenesis."

reach
"On the other hand P53 also has been related with DNMT3b, since it has been identified that the hypermethylation of p53 promoter by DNMT3b causes a decrease of its expression level and promotes an increase of cell proliferation [XREF_BIBR]."

reach
"MSPs of p53 and p21 were performed and revealed that silencing of DNMT3B decreased methylation of p53 and p21, respectively (XREF_FIG C and 5D)."

reach
"These findings provide further evidence that DNMT3B mediates PM2.5-induced hypermethylation of P53 promoter."

reach
"XREF_BIBR, XREF_BIBR Furthermore, note that silencing of DNMT3B decreased methylation of p53 and p21, respectively."
