SRSF3 and glioblastoma: This inhibition led to an increase in the expression of the downstream SRSF3 EX4 subtype, and the SRSF3 EX4 subtype interacted with two other splicing factors, polypyrimidine tract binding protein 1 (PTBP1) and PTBP2, thereby significantly suppressing the migration of GBM cells (Barbagallo et al., 2018; Barbagallo et al., 2021).
