Linc01133 promotes proliferation and metastasis of human renal cell carcinoma through sponging miR-760

Renal cell carcinoma (RCC) is one of the most frequent human tumors and has brought great threats to the health of the people around the globe. It was reported that linc01133, a long non-coding RNA (lncRNA), was involved in the pathogenesis and development of several human cancer. But the biological role of linc01133 in RCC is still not understood. The present study aimed to investigate the biological functions of linc01133 in RCC. We did some biological experiments in this study, including quantitative real-time polymerase chain reaction (qRT-PCR), western blotting, MTT assay, wound healing assay, Transwell invasion assay and xenograft tumor assay. In this study, we found the expression levels of linc01133 markedly increased in the RCC tissues compared with the normal tissues. And we found that the over-expressing of linc01133 promoted cell proliferation, migration and invasion, the interfering of linc01133 inhibited cell proliferation, migration and invasion. Furthermore, we found that the interfering of linc01133 inhibited tumor growth in murine xenograft models. Additionally, we found that linc01133 promotes RCC cell proliferation, migration and invasion through sponging miR-760. Collectively, our work preliminarily illuminated the tumor-promoting role of linc01133 in RCC and the potential molecular mechanism. Thus, our study may provide some evidence for the treatment of RCC.

Automated summary

This study found that the expression levels of linc01133 were significantly increased in RCC tissues, and overexpression of linc01133 promoted cell proliferation, migration, and invasion while interference of linc01133 inhibited these processes.
