To further confirm the biological function of GALNS in NPC cells, we silenced the gene expression using two siRNAs and confirmed reduced expression of GALNS mRNA (Fig. 2A) and protein (Fig. 2B, C) in the CNE2 and HONE1 cells transfected with GALNS siRNAs compared to the controls. The gene discussed is GALNS; the disease is nasopharyngeal carcinoma.
