USP39 activates EGFR. 4 / 6
| 4

reach
"To verify whether the regulatory effect of USP39 was EGFR specific, ectopic expression of USP39 were performed in PC-3 and DU145 cells, which showed that overexpressed USP39 upregulated EGFR mRNA and protein levels, indicating that EGFR is a downstream target of USP39."

reach
"It was found in our previous study that USP39 knockdown could inhibit the abnormal proliferation of prostate cancer cells by inhibiting the splicing maturation and transcriptional prolongation of EGFR mRNA [16]."

reach
"We hypothesized that USP39 could up-regulate EGFR by increasing the pre-mRNA splicing."

reach
"The results demonstrated that the level of the 3 '-end of EGFR decreased (P = 0.0015) more sharply than that of the 5 '-end (P = 0.0069), and the ratio ofthe 3 '-end to 5 '-end levels was significant decreased (P = 0.0297), implying that knockdown of USP39 might inhibit the transcription elongation of EGFR, and might produce unstable EGFR mRNA fragments lacking the 3 '-UTR."
