In a study involving CLI-5 and A549 lung adenocarcinoma cells, resveratrol downregulated miR-520h and triggered miR-520h-mediated signal cascade, resulting in inhibition of forkhead box C2 (FOXC2) and subsequent suppression of tumour metastasis in both in vitro and in vivo models. Here, FOXC2 is linked to lung adenocarcinoma.
