Abstract

MicroRNAs (miRNAs/miRs), consisting of ~22 nucleotides of single‑stranded RNA, participate in post‑transcriptional gene regulation by binding to the 3'‑untranslated region (UTR) of mRNAs, repressing their translation and promoting their degradation. Studies have shown that certain miRNAs play a key role in the control of various cellular activities, such as inhibiting inflammation, modulating cell differentiation and suppressing cancer growth. The role of miR‑146a in the immune response and in the pathogenesis of hepatocellular carcinoma (HCC) has also been investigated. Although some studies have shown that increased miR‑146a levels are associated with HCC, others have revealed that miR‑146a suppresses cancer cell proliferation, invasion and metastasis. Toll‑like receptor 4 (TLR4) signaling has an important role in regulating innate and adaptive immune responses. In addition, TLR4 is functionally expressed in HCC cells and promotes HCC cell proliferation, which can be regulated by miR‑146a. The present review focuses on the recent progress in analyzing the multiple roles of miR‑146a in mediating the TLR4 pathway and adaptive immune response. Finally, the function of miR‑146a in the pathogenesis of HCC is also discussed.
