Expression of HOXC13 in PCa tissues. A Full view of IHC staining for HOXC13 expression (147 cases available after excluding 3 cases without staining). B Expression statistics of HOXC13 in paracancerous tissues (n = 49) and PCa tissues (n = 98) and PCa tissues with GS < 8 (n = 53) and GS ≥ 8 (n = 45). C Expression statistics of HOXC13 in PCa tissue with stage I (n = 6), stage II (n = 47), stage III (n = 21), stage IV (n = 19) and stage V (n = 26). D Expression of HOXC13 in PCa tissues with different tumor stages (stage I to stage V). E Correlation between HOXC13 expression and DNA damage repair levels (r = 0.19, P < 0.001). (*P < 0.05, ***P < 0.001)
