A set of 72 differentially expressed miRNAs provide a molecular signature for pancreatic cancer

Project description:MicroRNAs (miRNAs) are short single-stranded RNA molecules that have a critical role in the regulation of gene expression. Alterations in miRNA expression levels have been observed in multiple tumor types and there is clear evidence on their active involvement in cancer development. Here, a comprehensive miRNA expression profiling in 16 pancreatic cancer cell lines and four normal pancreatic samples provided a specific molecular signature for pancreatic cancer and enabled us to identify 72 differentially expressed miRNAs with approximately half of them being up- and half downregulated in cancer cells as compared to normal samples. Of these, miR-31 was selected for further functional analyses based on its interesting M-bM-^@M-^\on-offM-bM-^@M-^] type expression profile, i.e. very low or even absent expression in normal pancreas and in six of the pancreatic cancer samples but extremely high expression in the remaining ten cell lines. Quite unexpectedly, both the inhibition of miR-31 in AsPC-1 and HPAF-II pancreatic cancer cells with high endogenous expression and forced expression of miR-31 in MIA PaCa-2 with low endogenous levels led to reduced cell proliferation, migration and invasion. More importantly, in AsPC-1 cells further enhancement of miR-31 also resulted in reduced cell migration and invasion, implicating that the level of miR-31 is critical for these phenotypes. We also identified novel miR-31 target genes, APBB2 and RSBN1, that might contribute to cancer pathogenesis. This study highlights a specific miRNA expression pattern in pancreatic cancer and reveals that manipulation of miR-31 expression leads to reduced cell migration and invasion in pancreatic cancer. 16 pancreatic cancer cell lines and 4 normal pancreatic RNA samples were hybridized on Agilent vs1 miRNA microarrays. Pool of four normal samples was hybridized on each slide to allow normalization between slides.

Of these, miR-31 was selected for further functional analyses based on its interesting “on-off” type expression profile, i.e. very low or even absent expression in normal pancreas and in six of the pancreatic cancer samples but extremely high expression in the remaining ten cell lines. Quite unexpectedly, both the inhibition of miR-31 in AsPC-1 and HPAF-II pancreatic cancer cells with high endogenous expression and forced expression of miR-31 in MIA PaCa-2 with low endogenous levels led to reduced cell proliferation, migration and invasion.

Identification of differentially expressed miRNAs in HCC cell lines compared with normal livers

Project description:To explore functionally crucial tumor-suppressive (TS)-miRNAs in hepatocellular carcinoma (HCC), we performed integrative function- and expression-based screenings of TS-miRNAs in six HCC cell lines. The screenings identified seven miRNAs, which showed growth-suppressive activities through the overexpression of each miRNA and were endogenously downregulated in HCC cell lines. Further expression analyses using a large panel of HCC cell lines and primary tumors demonstrated four miRNAs, miR-101, -195, -378 and -497, as candidate TS-miRNAs frequently silenced in HCCs. Among them, two clustered miRNAs miR-195 and miR-497 showed significant growth-suppressive activity with induction of G1 arrest. Comprehensive exploration of their targets using Argonute2-immunoprecipitation-deep-sequencing (Ago2-IP-seq) and genome-wide expression profiling after their overexpression, successfully identified a set of cell-cycle regulators, including CCNE1, CDC25A, CCND3, CDK4, and BTRC. Our results suggest the molecular pathway regulating cell cycle progression to be integrally altered by downregulation of miR-195 and miR-497 expression, leading to aberrant cell proliferation in hepatocarcinogenesis.

Protein expression profile of miR-33b overexpressing ES-2 cells upon OCM treatment

Project description:Omentum conditioned medium (OCM) is known to enhance ovarian cancer oncogenesis. In this study, miR-33b exerts tumor suppressive effects on ovarian cancer cells in response to omentum conditioned medium (OCM) treatment. To identify the molecular mechanism and main biological pathways involved in the tumor inhibiting activity by miR-33b in the ovarian cancer metastasis. To achieve this, miR-33b was stably overexpressed in ovarian cancer cell line ES-2, and the protein expression profile of miR-33b overexpressing ES-2 cells upon OCM treatment was determined.
