MicroRNA-150 promotes cervical cancer cell growth and survival by targeting FOXO4.

ABSTRACT:

Background

Dysregulation of microRNA-150 (miR-150) is commonly observed in solid tumor and has been reported to be involved in multiple important biological processes, such as cell proliferation, apoptosis, and metastasis. Elevated miR-150 level was also detected in cervical carcinoma, whereas its function in cancer progression has not been studied yet.

Methods

The expression of miRNA-150 in cervical carcinoma was compared with normal cervical tissue and using qRT-PCR. The effects of miR-150 on cell cycle and apoptosis, as well as the expression of cycle- and apoptosis-related genes, were determined using flow cytometry, TUNEL assay, qRT-PCR, and Western blot, respectively. The direct target of miR-150 was confirmed using 3' untranslated region (UTR) luciferase reporter assay.

Results

miR-150 promotes cervical cancer cell survival and growth, while the inhibition of miR-150 suppresses these actions. miR-150 also induced the cell cycle progression from G1/G0 to S phase, resulting in an enhancement of growth. Several cell cycle- and apoptosis-related genes, CyclinD1, p27, BIM, and FASL were modulated by miR-150. Moreover, miR-150 directly reduced the expression of FOXO4, which regulates the expression of CyclinD1, p27, BIM, and FASL, by targeting its 3' UTR.

Conclusion

Taken together, our data demonstrated that elevated miR-150 targets FOXO4 expression and therefore regulates multiple genes expression, resulting in cervical cancer cell growth and survival.

Project description:IntroductionMicroRNAs are small non-coding RNAs that are involved in the post-transcriptional negative regulation of mRNAs. MicroRNA 510 (miR-510) was initially shown to have a potential oncogenic role in breast cancer by the observation of its elevated levels in human breast tumor samples when compared to matched non-tumor samples. Few targets have been identified for miR-510. However, as microRNAs function through the negative regulation of their direct targets, the identification of those targets is critical for the understanding of their functional role in breast cancer.MethodsBreast cancer cell lines were transfected with pre-miR-510 or antisense miR-510 and western blotting and quantitative real time PCR were performed. Functional assays performed included cell growth, migration, invasion, colony formation, cytotoxicity and in vivo tumor growth. We performed a PCR assay to identify novel direct targets of miR-510. The study focused on peroxiredoxin 1 (PRDX1) as it was identified through our screen and was bioinformatically predicted to contain a miR-510 seed site in its 3' untranslated region (3'UTR). Luciferase reporter assays and site-directed mutagenesis were performed to confirm PRDX1 as a direct target. The Student's two-sided, paired t-test was used and a P-value less than 0.05 was considered significant.ResultsWe show that miR-510 overexpression in non-transformed and breast cancer cells can increase their cell growth, migration, invasion and colony formation in vitro. We also observed increased tumor growth when miR-510 was overexpressed in vivo. We identified PRDX1 through a novel PCR screen and confirmed it as a direct target using luciferase reporter assays. The reintroduction of PRDX1 into breast cancer cell lines without its regulatory 3'UTR confirmed that miR-510 was mediating its migratory phenotype at least in part through the negative regulation of PRDX1. Furthermore, the PI3K/Akt pathway was identified as a positive regulator of miR-510 both in vitro and in vivo.ConclusionsIn this study, we provide evidence to support a role for miR-510 as a novel oncomir. We show that miR-510 directly binds to the 3'UTR of PRDX1 and blocks its protein expression, thereby suppressing migration of human breast cancer cells. Taken together, these data support a pivotal role for miR-510 in breast cancer progression and suggest it as a potential therapeutic target in breast cancer patients.
