RNA-seq in breast cancer cell lines after manipulation of miR-23b expression

Project description:RNA sequencing technology has been carried out in order to evaluate mRNA expression changes after manipulation of miR-23b in both MCF-7 and MDA-MB-231 breast cancer cell lines Our study implicates miR-23b in cytoskeletal remodeling in breast cancer. To evaluate the entire set of genes modulated by miR-23b we performed RNA-seq after ectopic manipulation of this miRNA in breast cancer cell lines. We over-expressed this miRNA in MCF-7 epithelial cancer cell lines and also reduced its activity by stably transfecting MDA-MB-231 mesenchymal-like cancer cell lines with a specific sponge vector. RNA-seq analysis revealed a number of candidate targets of this miRNA.

RNA-sequencing (RNA-seq) in breast cancer cell lines after ectopic manipulation of miR-26a expression

Project description:RNA sequencing technology has been carried out in order to evaluate mRNA expression changes after manipulation of miR-26a in both MCF-7 and MDA-MB-231 breast cancer cell lines. To evaluate the entire set of genes modulated by miR-26a in breast cancer, we performed RNA-seq after ectopic manipulation of this miRNA. We over-expressed miR-26a in MCF-7 epithelial cancer cell lines and also reduced its activity by stably transfecting MDA-MB-231 mesenchymal-like cancer cell lines with a specific sponge vector. GO terms and pathway enriched analysis of the transcripts that significantly change upon miR-26 ectopic manipulation implicates miR-26ab in cell cycle, apoptosis, cell spreading and cell adhesion in breast cancer

Overexpression of miR-23b-3b+miR-218-5p+miR-124-3p differentially modifies the transcriptome of C-33A and CaSki cells and the regulation of cellular processes involved in the progression of cervical cancer

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.

Differentially Expressed Genes in C-33A and CaSki Cells Overexpressing miR-124-3p, miR-23b-3p, or miR-218-5p Modulate Processes and Pathways Involved in Cervical Cancer Progression

Project description:Aberrant expression of oncomicroRNAs and tumor suppressor miRNAs (tsmiRs) contributes to the carcinogenesis and progression of cervical cancer (CC). miR-124-3p, miR-23b-3p, and miR-218-5p are tsmiRs that modulate oncogenes regulating cellular processes implicated in CC progression. This research aimed to explore transcriptomic changes in C-33A and CaSki cells following the overexpression of miR-124-3p, miR-23b-3p, and miR-218-5p, and to identify the biological processes (BPs) and pathways modulated by differentially expressed genes (DEGs). A total of 100 nM of miR-124-3p, miR-23b-3p, and miR-218-5p mimetics were transfected into C-33A and CaSki cells, and transcriptome changes were analyzed using RNA-seq. The Galaxy and R-Studio platforms were employed to identify DEGs, while BPs and pathways regulated by DEGs were identified through the DAVID platform. Transcriptional changes revealed both differences and similarities between cell lines and miRNAs. In C-33A cells, miR-124-3p and miR-218 regulated direct and indirect targets involved in the cell cycle and apoptosis. In CaSki cells, apoptosis and viral carcinogenesis were regulated by genes modulated directly or indirectly by miR-124-3p and miR-23b-3p. These tsmiRs demonstrated synergistic activity, regulating multiple transcripts that modulate processes and pathways involved in CC progression, with or without HPV. These findings suggest that miR-124-3p, miR-23b-3p, and miR-218-5p may represent promising therapeutic alternatives for CC treatment.

Differentially expressed genes by anti tumor treatment in human cancer cell lines

Project description:To identify differentially expressed genes by anti cancer treatments (microRNAs, siRNAs and chemical compounds) in human cancer, several cell lines (prostate cancer, renal cell carcinoma and head and neck squamous cell carcinoma) were subjected to Agilent whole genome microarrays. Human cancer cell lines (PC3, DU145, LNCap, A498, 786-O, FaDu and SAS) were treated with miRNAs (miR-145, miR-375, miR-23b, miR-24, miR-27b and miR-29a), siRNAs (si-CAV2, si-LAMB3 and si-GOLM1) and chemical compunds (genistein, wogonin and CXCL10).
