To identify the underlying mechanism of FASN overexpression associated with NPC cell resistance to radiotherapy, we performed a real-time PCR array to examine the impact of FASN on the expression of Wnt signaling effectors, because previous studies suggested a role of FASN knockdown in the attenuated Wnt signaling pathway16,17 (Supplementary Table S1). This evidence concerns the gene FASN and nasopharyngeal carcinoma.
