USP22 activates MYC. 13 / 16
| 13

reach
"Furthermore, overexpression of USP22 stimulates breast cancer cell growth and colony formation, and increases c-Myc tumorigenic activity."

reach
"While these outcomes could occur via USP22 mediated MYC and CyclinD2 and/or BMI-1-mediated modulation, AR activity promotes tumorigenesis in several of these tumor types, including bladder, HCC and breast carcinoma."

reach
"USP22 depletion in the lung cancer cells decreases the transcriptional ability of Myc [4]."

reach
"In this study, we found that USP22 overexpression induces c-myc upregulation in both SGC7901 cells and tumor tissue, consistent with previous reports."

reach
"Evidently, HnRNPA1 is a downstream transcription regulator of c-Myc (proto-oncogene) whereas USP22 positively regulates c-Myc stability and promotes tumorigenesis [XREF_BIBR, XREF_BIBR]."

reach
"C-Myc abundance is also indirectly increased by the activity of USP22 on its substrate SIRT1, a NAD dependent protein deacetylase [XREF_BIBR] (see Section 7), but this is not observed in all cell types [XREF_BIBR]."

reach
"Decreased levels of USP22 reduce the ability of c-MYC, which can stimulate activation of AP4 to directly or indirectly induce EMT [XREF_BIBR], activating the transcription of its targets [XREF_BIBR, XREF_BIBR]."

reach
"USP22 increases the stability and tumorigenic activity of c-Myc in breast cancer cells [30]."

reach
"In addition, USP22 expression was shown to increase the abundance of c-Myc and the androgen receptor itself [XREF_BIBR, XREF_BIBR, XREF_BIBR]."

reach
"Studies herein suggest that USP22 mediated MYC regulation in PCa is likely gene selective, based on USP22 increasing gene expression of AR/MYC co-regulated target (ODC) but not of multiple MYC targets."

reach
"USP22 increased c-Myc stability via deubiquitination in breast cancer cells."

reach
"Deubiquitinating enzyme USP22 positively regulates c-Myc stability and tumorigenic activity in mammalian and breast cancer cells."

reach
"In conclusion, the present study reveals that USP22 in breast cancer cell lines increases c-Myc stability through c-Myc deubiquitination, which is closely correlated with breast cancer progression."
