GOLIM4 and nasopharyngeal carcinoma: Next, we knocked down the expression of RBFOX2 in NPC cell lines using siRNAs (Figure S5B, Supporting Information), and observed the alternative splicing event for GOLIM4, of which the exon‐7 was almost completely skipped or excluded, resulting in GOLIM4‐S isoform, as compared with the control groups (Figure 3B; Figure S5D, Supporting Information).
