SRSF3 and nasopharyngeal carcinoma: To assess the clinical significance of SRSF3 expression, we examined the protein expression of SRSF3 in NPC using immunohistochemistry (IHC) assays and performed survival analysis, which revealed that higher expression of SRSF3 was significantly associated with worse prognosis in individuals diagnosed with NPC (Fig. 1E, F, Supplementary Fig. 1C).
