METTL3 decreases the amount of USP4. 5 / 5
| 5

reach
"The present study demonstrates that metformin can repress the expression of THRAP3, RBM25, and USP4 by inhibiting METTL3-mediated m6A modification, which in turn hamper cell proliferation and promotes cell apoptosis."

reach
"Moreover, USP4 promoter transcriptional activity was not affected upon METTL3 knockdown, excluding the possibility that METTL3 downregulation inhibited USP4 transcription."

reach
"And thus, we chose USP4, USP8, USP11, USP25 and USP28 for further analyses, and western blotting revealled that METTL3 knockdown markedly increased USP4 protein levels."

reach
"Given the key role of m 6 A mRNA methylation in affecting mRNA stability, it was reasonable to speculate that METTL3 knockdown reduces the m 6 A modification levels in USP4 mRNA and thus increase USP4 mRNA levels by atenuating the inhibitory effect of m 6 A modification on USP4 mRNA stability."

reach
"We next found that METTL3 knockdown significantly upregulated USP4 mRNA levels in PCa cells."
