USP39 inhibits TP53. 7 / 7
| 1 6

reach
"USP39 attenuates the antitumor activity of cisplatin on colon cancer cells dependent on p53."

reach
"on A549 cells to confirm the key role of p53, the WB result demonstrated that exposure to PFT-alpha (30 or 40 mum/48 h) clearly inhibited the p53 pathway activation, which activated by USP39 knockdown in A549 cells."

reach
"Altogether, these results suggest that USP39 knockdown causes a significant accumulation of p53 via regulating both transcriptional levels and post-translational modifications of p53."

reach
"Moreover, depletion of USP39 blocked activation of Akt, mTOR, p53, and PARP signaling pathways."

eidos
"Further studies demonstrated that depletion of USP39 results in an upregulation of p53 through prolonging its half-life and activating its transcriptional activation activity ."

reach
"Meanwhile, we found that USP39 knockdown also activates the p53 pathway, upregulation of p53, p-p53 (S15), p21 and BAX in HCC827 cells."

reach
"Furthermore, USP39 knockdown increased the stability of the p53 protein by prolonging its half-life."
