USP9X increases the amount of MCL1. 22 / 22
| 22

reach
"While Usp9X is known to modulate Mcl-1 expression, our observed effects of Usp9X manipulation on Bag3 and Bcl-2 have not been previously described and may suggest that Usp9X also interacts with Bag3 as well as Bcl-2."

reach
"WP1130 is an inhibitor of USP9x, which is known to upregulate the level of Mcl-1, leading to apoptosis."

reach
"The decreased expression of USP9X subsequently reduced Mcl-1 expression and increased Bax expression, which may be the cause of apoptosis in laryngeal cancer cells."

reach
"Usp9X modulates Mcl-1 levels and counteracts apoptosis in cancer cells [XREF_BIBR]."

reach
"Knockdown of the de-ubiquitinase Usp9x of MCL1 can decrease the protein level of MCL1 and increase the sensitivity of colon carcinoma and leukemia cells to ABT-737 [ 55 ]."

reach
"Furthermore, knockdown of Usp9X or Bag3 depleted endogenous Mcl-1 protein levels and in turn enhanced apoptosis induced through Bcl-2 and Bcl-xL inhibition [XREF_BIBR]."

reach
"In line with these observations, MCL1 protein levels were downregulated by depletion of USP9X but not USP13 (Figure S6D)."

reach
"We have shown previously that USP9X inhibition by WP1130 reduces MCL-1 levels, promotes apoptosis and increases tumor cell sensitivity to chemotherapy [XREF_BIBR]."

reach
"USP9X positively promotes the expression of Mcl-1."

reach
"Similar distinction was also observed for Mcl-1, one observed substrate of Usp9x, where Usp9x KD increased Mcl-1 levels in 8041 cells but decreased Mcl-1 in MIAPACA2 cells."

reach
"In addition, the blocking of USP9X activities using a small-molecule inhibitor decreases Mcl-1 expression by promoting its degradation and thus sensitizes tumor cells to chemotherapeutic agents."

reach
"XREF_BIBR More recently, in non small cell lung carcinoma, inhibition of USP9X by either siRNA knockdown or via a small molecule inhibitor WP1130 decreased MCL1 expression and sensitized cells to radiation therapy."

reach
"Indeed, USP9X knockdown decreases the level of MCL1 protein, sensitizes MCL1-resistant colon carcinoma and leukemia cells to ABT-737 , and sensitizes radioresistant cells to apoptosis induction ."

reach
"Based on our previously published observation that Usp9X induces a decline of Mcl-1 protein levels in GBM cells , we hypothesized that similar effects would be observed in MPNST cells."

reach
"Moreover, examination of Mcl-1 levels 48 h after irradiation with 0 Gy and 10 Gy revealed that USP9x knockdown prevented the radiation-induced increase of Mcl-1 levels in LNCaP cells, while only minor effects of USP9x knockdown on MCL-1 levels were detected in irradiated PC3 cells (Figure 6F)."

reach
"Finally, we demonstrated that a knockdown of USP9x reduced Mcl-1 levels and sensitized particularly LNCaP cells to radiotherapy.Our findings suggest that deubiquitinase USP9x is responsible for upregulated Mcl-1 protein levels, thereby contributing to prostate cancer progression and therapy resistance."

reach
"USP9x-mediated stabilization of Mcl-1 protein levels by preventing its degradation was described before as a mechanism that increased apoptosis threshold in other tumor entities [22,33]."

reach
"Mechanistically, Usp9X knockdown caused concomitant suppression of Bag3, Mcl-1 and Bcl-2 expression, which remarkably recapitulates the effects of CP-d and n-ATF 5-S1 on these molecules."

reach
"Inhibition of USP9X and USP24 increases the ubiquitination of MCL-1 and decreases the level of MCL-1."

reach
"We also observed that Usp9x KD decreased Mcl-1 levels in MIAPACA2 cells but increased Mcl-1 levels in 8041 cells."

reach
"Thus, EOAI3402143, an inhibitor of the deubiquitinases Usp9x and Usp24, reduced Mcl-1 protein levels in MM cells and lowered disease burden in an animal model of MM [98]."

reach
"These ITCs increased Mcl-1 ubiquitination and either ITC treatment or RNAi mediated silencing of USP9x decreased Mcl-1 levels, consistent with the notion that USP9x is a primary target of ITC activity."
