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:Gene expression profiling of immortalized human mesenchymal stem cells with hTERT/E6/E7 transfected MSCs. hTERT may change gene expression in MSCs. Goal was to determine the gene expressions of immortalized MSCs.
Project description:Gene methylation profiling of immortalized human mesenchymal stem cells comparing HPV E6/E7-transfected MSCs cells with human telomerase reverse transcriptase (hTERT)- and HPV E6/E7-transfected MSCs. hTERT may increase gene methylation in MSCs. Goal was to determine the effects of different transfected genes on global gene methylation in MSCs.
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: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.

Project description:To identify target genes of cancer-related microRNAs in human cancer, several cell lines (bladder cancer, prostate cancer, renal cell carcinoma, esophageal squamous cell carcinoma, and head and neck squamous cell carcinoma) were subjected to Agilent whole genome microarrays. Human cancer cell lines (BOY, T24, A498, 786-O, caki-1, LNCap, PC3, TE2, T.Tn, FaDu, SAS, HSC3, and IMC-3) were transfected with miRNAs (miR-375, miR-145, miR-200a, miR-200b, miR-200c, miR-141, miR-429, miR-138, miR-218, miR-874, miR-31, miR-222, miR-1285, and miR-206) or siRNAs (si-FOXA1_1, si-FOXA1_3, and si-TAGLN2). The miRNA-transfected human cancer cell lines were compared to control cell lines.
