We also performed qRT-PCR and western blot experiments on various in vitro cultured nasopharyngeal carcinoma cell lines, which further substantiated our findings that ELAVL1 expression was considerably higher in nasopharyngeal carcinoma cells than in normal cells, at both the mRNA and protein levels (Fig. 1C, D). The gene discussed is ELAVL1; the disease is nasopharyngeal carcinoma.
