a LNCaP, C4-2, VCaP and PC-3 cells were infected with shScramble or shOTUD6A, and cell growth ratio were examined by SRB assays. Data were shown as mean ± SD of three independent experiments. ***P < 0.001. IB analysis results of the whole cell lysates (WCLs) were shown on the top of curves. b Representative images of the colony formation assay of LNCaP, C4-2, VCaP, and PC-3 cells infected with shScramble or shOTUD6A. Scale bars: 5 mm. The statistic results were shown as mean ± SD of three independent experiments. ***P < 0.001. shScr: shScramble; sh6A#1: shOTUD6A#1; sh6A#2: shOTUD6A#2. c, d IB analysis (c) and colony formation (d) images of C4-2 cells transfected with the indicated plasmids. WT: wild-type. Scale bars: 5 mm. e, f Stable C4-2-shScramble or C4-2-shOTUD6A cells were randomly injected subcutaneously into 6-week-old NOD/SCID mice and then tumor growth curves were constructed (e), and dissected tumors were collected and weighed (f) around 5 weeks later (n = 6). Data represented the mean ± SEM. Statistical significance was determined by two-tailed unpaired Student’s t-test, **P < 0.01, scale bar: 1 cm. g, h Indicated stable Myc-CaP cells were randomly injected subcutaneously into 6-week-old FVB mice and then tumor growth curves were constructed (g), and dissected tumors were collected and weighed (h) 4 weeks later (n = 6). Data represented the mean ± SEM. Statistical significance was determined by two-tailed unpaired Student’s t-test, **P < 0.01, ***P < 0.001, scale bar: 1 cm. 6A WT: wild-type OTUD6A; 6A C153A: OTUD6A-C153A mutant.
