By bioinformatics and luciferase reporter assays, circ_0044516 was verified to downregulate miR-29a-3p expression and negatively related to miR-29a-3p expression levels in prostate cancer.
Our recent studies of microRNA (miRNA) expression signatures of prostate cancer (PCa) showed that six miRNAs (specifically, miR-26a, miR-26b, miR-29a, miR-29b, miR-29c and miR-218) were markedly reduced in cancer tissues.
The increased levels of miR-29a and miR-1256 by isoflavone treatment resulted in decreased expression of TRIM68 and PGK-1, which is mechanistically linked with inhibition of PCa cell growth and invasion.
