USP22 decreases the amount of CDKN1A. 9 / 9
| 9

reach
"GSK3beta- and USP22 dependent KDM1A stabilization is required for the demethylation of histone H3K4, thereby repressing BMP2, CDKN1A and GATA6 transcription, which results in cancer stem cell self-renewal and glioblastoma tumorigenesis."

reach
"USP22 has also been demonstrated to inhibit transcription of the p21 gene by deubiquitinating the transcriptional regulator, FBP1, leading to cell proliferation and tumorigenesis."

reach
"USP22-mediated deubiquitination of PTEN inhibits pancreatic cancer progression by inducing p21 expression."

reach
"Recent studies have demonstrated that USP22 can inhibit the transcription of the p21 gene by de-ubiquitinating the transcriptional regulator FBP1, leading to cell proliferation and tumorigenesis [XREF_BIBR]."

reach
"In MGC-803 cells and SGC-7901 cells, knockdown of USP22 and BMI1 both increased P21 expression and reduced the expression of CSC stemness genes of CD133 and SOX2."

reach
"USP22 also suppresses CDKN1A and p21 -locus expression by deubiquitinating its transcriptional repressor FBP1 (Atanassov and Dent, 2011), and acts as a negative regulator of the tumor suppressor p53 b[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"We found that USP22 silencing in A549 and NCI-H460 cells increased the protein expression of p53, p21 and Bax, the key p53 signal molecules (XREF_FIG A), suggesting that p53 activation plays a role in USP22 silencing induced growth inhibition."

reach
"Furthermore, our results showed that USP22 deletion caused down -- regulation of cyclin D2 expression and up -- regulation of p15 and p21 expression."

reach
"We found that USP22 depletion inhibited the proliferation of the human GC cell lines MGC-803 and SGC-7901 cells and increased expression of P21, indicating cell cycle arrest [XREF_BIBR]."
