Both CNE2 and 6-10B with exogenous supplementation of WNT5a protein showed increased cell viability at radiation doses with 4 and 6Gy (Fig. 2B, D), which may indicate that WNT5a protein promotes radiation resistance of nasopharyngeal carcinoma in vitro. The gene discussed is WNT5A; the disease is nasopharyngeal carcinoma.
