Gastric cancer (GC) is one of the most common malignancies worldwide and has high morbidity and mortality rates. It is essential to elucidate the molecular events of GC proliferation and invasion, which will provide new therapeutic targets for GC. The inactivation of transforming growth factor‐β receptor 2 (TGFβR2) correlates with cancer cell growth and metastasis, but the mechanisms underlying the downregulation of TGFβR2 expression remain unknown. MicroRNAs (miRNAs) act as post‐transcriptional regulators and play a key role in the development of cancers. Bioinformatics analysis and luciferase reporter assays have shown that miR‐155 directly binds to the 3′‐UTR of TGFβR2 mRNA. In this study, we found that the TGFβR2 protein levels, but not mRNA levels, were downregulated in GC tissues, and the levels of miR‐155 were significantly increased in GC tissues. We deduced that miR‐155 was inversely correlated with TGFβR2 in GC cells. In vitro studies showed that overexpression of miR‐155 in SGC7901 inhibited the expression of TGFβR2 and then promoted GC cell proliferation and migration, whereas miR‐155 inhibitor showed opposite effects. In addition, the tumor‐suppressing function of TGFβR2 was verified by using siRNA and TGFβR2 overexpressing plasmids. The results showed that miR‐155 promotes cell growth and migration by negatively regulating TGFβR2. Thus, miR‐155‐regulated TGFβR2 as a potential therapeutic target in GC.

Deregulation of microRNAs contributes to the abnormal cell growth which is frequently observed in cancer. In the current study, we detected the expression and regulatory relationship between miR‐10a and Lysine‐specific demethylase 4A (KDM4A) to reveal their function in prostate cancer (PCa) progression. We found that miR‐10a levels were significantly decreased in PCa cell lines in comparison with the normal epithelial cell line RWPE‐1. Downregulation of miR‐10a levels was also observed in tumor tissues from PCa patients compared with the adjacent normal tissues. Enhanced expression of miR‐10a inhibited cell proliferation and colony forming capability of PCa cells. In addition, quantitative real‐time polymerase chain reaction and Western blot analysis showed a significant decrease of KDM4A in response to miR‐10a elevation in PCa cells. Using dual luciferase assay, we confirmed that KDM4A was a target gene for miR‐10a. Furthermore, Western blot analysis indicated that miR‐10a overexpression inactivated YAP signaling and suppressed transcription of YAP target genes. Additionally, cell growth arrest and colony forming capacity inhibition induced by miR‐10a overexpression could be reversed by YAP overexpression in PCa cells. More importantly, miR‐10a mimics inhibited PC‐3 tumor growth in nude mice accompanied with a remarkable reduction of KDM4A and YAP expression. In conclusion, our results uncovered a tumor suppressor role of miR‐10a in PCa via negative regulation of KDM4A and its downstream Hippo‐YAP pathway.

“…Assays to quantify mature miRNAs were performed using TaqMan miRNA probes (Applied Biosystems, Foster City, CA, USA) according to the manufacturer's instructions. Quantitative RT-PCR was performed to quantify miRNA levels and mRNA levels (see our previous study for details [15]). The primers for PCR amplifications were as follows: KRAS (sense) 5'-GACTCTGAAGATGTACCTATGGTCCTA-3'; KRAS (antisense) 5'-CATCATCAACACCCTGTCTTGTC-3';GAPDH (sense) 5'-GATATTGTTGCCATCAATGAC-3';GAPDH (antisense) 5'-TTGATTTTGGAGGGATCTCG-3'.…”

Background/Aims: MicroRNAs (miRNAs) have emerged as major regulators of tumour development and progression in non-small cell lung cancer (NSCLC). However, the role of miR-193a-3p in NSCLC is still unclear. Methods: Quantitative RT-PCR was used to detect miR-193a-3p expression levels in NSCLC tumour tissues. CCK8, EdU and cell migration assays were performed to analyse the biological functions of miR-193a-3p in NSCLC cells. Luciferase reporter assays were used to validate the bioinformatics-predicted target genes of miR-193a-3p. Western blotting and RNA/DNA interference carried out to evaluate the association between miR-193a-3p and KRAS. Results: miR-193a-3p expression was decreased in the NSCLC tumour tissues. We investigated the biological effects of miR-193a-3p both in vivo and in vitro and found that enforced expression of miR-193a-3p inhibited tumour formation and suppressed cell proliferation and cell migration. KRAS was found to be a potential target of miR-193a-3p, and dual luciferase reporter assays showed that miR-193a-3p directly binds to the 3’-untranslated region (3’-UTR) of KRAS mRNA. In addition, we found that changing the expression of KRAS had the opposite results to those induced by miR-193a-3p in the NSCLC cells. Importantly, simultaneous overexpression of miR-193a-3p and KRAS could counteract the effects of both on cellular functions. Conclusion: These findings highlight an important role for miR-193a-3p as a tumour suppressor in NSCLC pathogenesis via the regulation of KRAS expression.
