SRSF9 and neoplasm: As shown in Fig. 3A–C, higher SRSF9 expression was significantly positively correlated with malignant characteristics of HCC, such as tumor stage III versus stage I (P = 0.0075); pathologic T3 versus T1 (P = 0.015); histologic grade G3 versus G1 (P = 0.0022), and G3 versus G2 (P = 0.019).
