Project description:We investigated the relative miRNA levels in primary prostate cancer samples from patients that had a subsequent recurrence event versus patients that did not. For one of the top miRNAs arising from this analysis, miR-33a, we carried out further investigation, including miRNA levels in normal and tumor prostate samples as well as PCa cell lines. Then, we performed a detailed functional analysis of mir-33a in LNCaP and VCaP PCa cells and evaluated proliferative, invasive and anchorage independent growth potential of cells upon overexpression and knockdown of miR-33a.

Project description:In this study, we aimed to investigate the functional roles of miR-33a in PCa.We investigated the relative miR-33a level in normal and tumor prostate samples as well as PCa cell lines. Then, we performed a detailed functional analysis of mir-33a in LNCaP and VCaP PCa cells and evaluated proliferative, invasive and anchorage independent growth potential of cells upon overexpression and knockdown of miR-33a. We next explored the potential direct targets of miR-33a in PCa cells via utilizing gene expression microarray analysis, bioinformatics search, further qRT-PCR, western blot, and luciferase assay confirmation. Our results demonstrated that miR-33a is significantly downregulated in PCa tumor samples and PCa cell lines, pointing its tumor suppressor potential in PCa. Overexpression and knockdown of miR-33a significantly altered the proliferative, invasive and anchorage independent growth potentials of cells through altering the expression of its direct target PIM1. Ectopic induction of MiR-33a expression reversed the impacts of PIM1 overexpression on cellular phenotypes associated with PCa progression. Our results suggest that mir-33a exerts its tumor suppressor potential through targeting its direct target PIM1 and carries crucial roles in PCa tumorigenesis.

Project description:Dysregulation of tumor suppressor miRNAs (tsmiRs) is associated with tumor progression in cancer. miR-23b-3p, miR-218-5p and miR-124-3p are tsmiRs in cervical cancer (CC) and regulate the translation of genes involved in metastasis-related biological processes. Objective. To analyze transcriptome changes in cervical cancer cell lines (C-33A HPV-negative and CaSki HPV-positive) overexpressing miR-23b-3b+miR-218-5p+miR-124-3p, to identify specific target transcripts common to all three miRNAs, as well as signaling pathways and cellular processes related to tumor progression. Methods. The transcriptome of C-33A and CaSki cells transfected with miR-23b-3b+miR-218-5p+miR-124-3p was analyzed by RNA-seq. Differentially expressed genes (DEGs) were subjected to Gene Ontology analysis on the DAVID platform. The function of under-regulated genes was analyzed on the GEPIA 2.0, Kaplan-Meier plotter and STRING platforms. On the TargetScanHuman platform it was determined which transcripts have MREs for miR-23b-3p, miR-218-5p and/or miR-124-3p in their 3`UTR region. Results. Simultaneous overexpression of miR-218-5p, miR-124-3p and miR-23b-3p induced changes in global gene expression in C-33A and CaSki cells. In C-33A cells, DEGs included 45 over- and 172 under-regulated transcripts; in CaSki, 125 transcripts were over- and 84 under-regulated. The under-regulated transcripts enrich proliferation, migration, apoptosis and angiogenesis; 20 of these genes are associated with overall survival (OS) in women with CC, and 18 of the 20 mRNAs have MREs for one, two or all three miRNAs. Conclusions. miR-23b-3b+miR-218-5p+miR-124-3p, differentially modify global gene expression in C-33A and CaSki cells. The results indicate that these miRNAs act synergistically and modulate CC progression through individual and shared targets by two or all three miRNAs.

Project description:To identify target genes of tumor suppressive microRNAs in human cancer, several cell lines (bladder cancer, prostate cancer, renal cell carcinoma, and head and neck squamous cell carcinoma) were subjected to Agilent whole genome microarrays. miR-517a, miR-218, miR-145, miR-1 and miR-874 function as tumor suppressors. Human cancer cell lines (BOY, T24, A498, PC3, DU145, FaDu, SAS, HSC3, IMC3) were transfected with miRNAs (miR-517a, miR-218, miR-145, miR-1, miR-874). The miRNA-transfected human cancer cell lines were compared to control cell lines.
