Abstract

Accumulating evidence suggests that some microRNAs (miRNAs) are involved in papillary thyroid carcinoma (PTC) progression. However, it remains necessary to elucidate the underlying molecular mechanisms involved. In the present study, we investigated the role of microRNA‑101 (miR‑101) in PTC via targeting of Ras‑related C3 botulinum toxin substrate 1 (Rac1). The results showed that miR‑101 was significantly downregulated in PTC tissues compared with adjacent normal tissues. Restoration of miR‑101 expression significantly inhibited cell proliferation in the K1 PTC cell line. Moreover, algorithm‑based and experimental strategies verified Rac1 as a direct target of miR‑101 in the K1 cell line. Taken together, these findings suggest that miR‑101 inhibited PTC growth via the downregulation of Rac1 expression, providing a better understanding of miRNA‑modulated signaling networks for future cancer therapeutics.
