To investigate whether GOLIM4‐L contributes to the tumorigenesis of NPC, we specifically knocked down the expression of GOLIM4‐L in two NPC cell lines (S26 and 5–8F) using siRNAs targeting the exon‐7 of GOLIM4, which did not influence the GOLIM4‐S isoform (Figure 2A; Figure S2A,B, Supporting Information). This evidence concerns the gene GOLIM4 and nasopharyngeal carcinoma.
