One of the targets of miR-199a-5p is Snai1. This zinc finger transcription factor is one of the best-known regulators of thyroid cancer by inducing epithelial–mesenchymal transition (EMT) through the repression of CDH1 (Wieczorek-Szukala and Lewinski 2021). This evidence concerns the gene SNAI1 and thyroid gland carcinoma.
