MICAL2 and nasopharyngeal carcinoma: Meanwhile, we observed that knockdown of hnRNPK or MICAL2 in S26-pSIN-seRNA cells inhibited the metastasis and invasion of NPC cells (Fig. 6M, N, Q, R), and overexpression of hnRNPK in S18-shseRNA#3 cells promoted the metastasis and invasion of NPC cells (Fig. 6O, P).
