Moreover, to further validate the oncogenic role of SRSF3 in NPC, we constructed NPC cell lines with stable overexpression of SRSF3 (Fig. 2I and Supplementary Fig. 2E, Supplementary File 1) and we observed remarkably enhanced proliferation and migration capacities of the NPC cells (Fig. 2J–L). This evidence concerns the gene SRSF3 and nasopharyngeal carcinoma.
