                                  "While the relationship between USP7 and EZH2 and its significance in NB pathogenesis have not yet been established, our results have shown direct correlations between USP7 downregulation induced by inhibition of its deubiquitinase activity via Almac4 or by USP7 depletion and EZH2 and N-Myc ubiquitination and protein degradation."

                                  "The TME includes adipocytes [3, 134], and one study showed that the exo-circ-deubiquitination (exo-circ-DB) derived from adipocytes upregulated the expression levels of USP7 and Cyclin A2 by sponging miR-34a and activating the USP7/CyclinA2 signalling pathway, thereby promoting the tumorigenesis and metastasis of HCC [135]."

                                  "IHC showed that expression levels of both USP7 and PD-L1 in the cancer tissues were significantly higher than those in the normal tissues (online supplemental figure S9), and USP7 levels were positively correlated with PD-L1 levels in cancer tissues(figure 7A, B), supporting USP7 as the deubiquitinase of PD-L1."
