Project description:To explore the mechanism and downstream pathways of ASH1-miR-375-YWHAZ axis in hepatocellular carcinoma (HCC). We performed microarray assay to identify the downstream genes of YWHAZ. As a result, we obtained 507 (245 upregulation and 262 downregulation) differentially expressed genes significantly affected by YWHAZ knockdown. Function enrichment analysis showed that these genes were enriched in the “Regulation of actin cytoskeleton” pathway which is related with cell migration and tumor metastasis. We also find that most of the autophagy-associated genes, such as ATG3, ATG5 and ATG7 and EMT related gene E-cadherin were highly correlated with YWHAZ and changed by silencing YWHAZ. Real-time quantitative RT-PCR was performed to verify the microarray results. In conclusion, the expression profile of many genes were significantly affected by YWHAZ knockdown, which helps to further explore the mechanism of the effects of ASH1-miR-375-YWHAZ axis in HCC.
Project description:We investigated the functional significance of ASH1-inducible miR-375 in terms of biologic phenotypes of ASH1-positive lung cancer cells. To this end, we conducted genome-wide expression profiling analysis of miR-375-transfected A549 cells. Microarray analysis using a Whole Human Genome 4 x 44K Microarray G4112F (Agilent) was conducted to examine changes in expression of potential target genes of miR-375 by transfection of Pre-miR-375 or Pre-miR-NC#2 (Ambion) in A549 cells, which were then harvested at 12, 24, 48, and 96 hours after transfection.

Project description:We report RNA sequencing data for miR-375 knockout and YAP overexpression lung carcinoid cells (H727). Lung carcinoids are variably aggressive and mechanistically understudied neuroendocrine neoplasms (NENs). Here, we identified and elucidated the function of a miR-375/yes-associated protein (YAP) axis in lung carcinoid (H727) cells. miR-375 and YAP are respectively high and low expressed in wild-type H727 cells. Following lentiviral CRISPR/Cas9-mediated miR-375 depletion, we identified distinct transcriptomic changes including dramatic YAP upregulation. Similarly, YAP overexpression resulted in distinct and partially overlapping transcriptomic changes, phenocopying the effects of miR-375 depletion in the same models as above. Pathways analysis and confirmatory real-time PCR studies of shared dysregulated targets indicate that this axis controls neuroendocrine related functions such as neural differentiation, exocytosis, and secretion. Taken together, we provide compelling evidence that a miR-375/YAP axis is a critical mediator of neuroendocrine differentiation and tumorigenesis in lung carcinoid cells.
Project description:Fibrolamellar carcinoma (FLC) is a rare liver cancer. Expression of miR-375 is significantly lost in primary FLC tumors compared to non-malignant liver. Here, we treated a FLC cell line with miR-375 mimic or scramble control to determine the function of miR-375 in FLC.

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).
