Figure Lengend Snippet: UCHL1 regulates cancer cell growth in vitro and in vivo (A) UCHL1 and SYP levels in 22Rv1-RFP, 22Rv1-UCHL1-OV (WT UCHL1), and 22Rv1-UCHL1(C90S) cells were determined by western blot (WB) (left). SOX2, CD56, SYP, and UCHL1 levels in UCHL1 knockout pool cells were assessed by WB (right). (B and C) Colony formation assays of 22Rv1 with or without WT UCHL1 or UCHL1(C90S) overexpression (B) and colony formation assays of TD-NEPC parental (no transfection) cells, CTL (transfection with control non-targeting sgRNA), and UCHL1 knockout (transfection with multi-sgRNA targeting UCHL1) single-cell selection clones (C). Scale bar, 1 cm. The percentage of colony area per well was quantified using ImageJ. All experiments were performed in triplicate. Error bars, SD. (D) Subcutaneous tumor growth (left) and tumor weight (right) of 22Rv1-RFP (n = 10) and 22Rv1-UCHL1-OV (n = 10). Error bars represent standard error of the mean (SEM). (E) IHC staining of UCHL1, androgen receptor (AR) and SYP, CgA, and CD56 in 22Rv1 xenografts. Scale bar, 10 μm. (F) Subcutaneous tumor growth of TD-NEPC parental (no transduction), CTL 1 and 2, and UCHL1 knockout 1, 2, and 3 single-cell selection clone xenografts. Error bars represent SEM. (G) Harvested tumors (left) and tumor weights (right) at the endpoint (scale bar, 1 cm). (H) IHC staining for UCHL1, SYP, CgA, and CD56 in TD-NEPC parental, CTL, and UCHL1 knockout (KO) xenografts. Scale bars, 10 μm. ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.005, ∗∗∗∗p < 0.001, determined by Student’s t test.
