Abstract
MicroRNAs (miRNAs) play a critical role in glioblastoma initiation and progression. PIWIL1, a human homolog of the PIWI family, has a critical effect on glioblastoma progression. In present study, we found that the expression of miR-154-5p was significantly lower in glioblastoma. Our results suggested that the overexpression of miR-154-5p suppressed proliferation and metastasis, induced apoptosis, whereas inhibiting the expression of miR-154-5p significantly promoted proliferation and metastasis of glioblastoma. We further proved that miR-154-5p directly integrated with the 3â²-UTR of PIWIL1 and reintroduction of PIWIL1 can rescue the phenotype changes induced by miR-154-5p. Taken together, our study reveals that miR-154-5p can counteract the malignant phenotypes of glioblastoma by targeting PIWIL1, which might be beneficial to reveal new therapeutic targets for glioblastoma.
