Identification of genes differentially expressed in lung cancer cells after the transfection of miR-221 or miR-222.

ABSTRACT: To evaluate involvement of miR-221 and miR-222 in lung cancer, we investigated the effects of miR-221 and miR-222 overexpression on six lung cancer cell lines as well as one immortalized normal human bronchial epithelial cell line. Two cell lines, H3255 and H1299 with no replicates were studied. Cells were transfected with miR-221, miR-222, or miR control. Microarray analysis was done to identify genes differentially expressed in lung cancer cells after the transfection of miR-221 or miR-222.

Both pro- and anti-oncogenic roles of miR-221 and miR-222 microRNAs are reported in several types of human cancers. A previous study suggested their oncogenic role in invasiveness in lung cancer, albeit only one cell line (H460) was used. To further evaluate involvement of miR-221 and miR-222 in lung cancer, we investigated the effects of miR-221 and miR-222 overexpression on six lung cancer cell lines, including H460, as well as one immortalized normal human bronchial epithelial cell line, HBEC ...[more]

Circulating microRNA profiles in patients with type-1 autoimmune hepatitis

Project description:Recent studies have demonstrated that micro (mi)RNA molecules can be detected in the circulation and can serve as potential biomarkers of various diseases. This study used microarray analysis to identify aberrantly expressed circulating miRNAs in patients with type 1 autoimmune hepatitis (AIH) compared with healthy controls. Patients with well-documented and untreated AIH were selected from the National Hospital Organization (NHO)-AIH-liver-network database. They underwent blood sampling and liver biopsy with inflammation grading and fibrosis staging before receiving treatment. To further confirm the microarray data, circulating expression levels of miR-21 and miR-122 were quantified by real-time quantitative polymerase chain reaction in 46 AIH patients, 40 patients with chronic hepatitis C (CHC), and 15 healthy controls. Consistent with the microarray data, serum levels of miR-21 were significantly elevated in AIH patients compared with CHC patients and healthy controls. miR-21 and miR-122 serum levels correlated with alanine aminotransferase levels. Circulating levels of miR-21 and miR-122 were significantly reduced in AIH patients with liver cirrhosis, and were inversely correlated with increased stages of fibrosis. By contrast, levels of circulating miR-21 showed a significant correlation with the histological grades of inflammation in AIH. We postulate that aberrantly expressed serum miRNAs are potential biomarkers of AIH and could be implicated in AIH pathogenesis. Alternations of miR-21 and miR-122 serum levels could reflect their putative roles in the mediation of inflammatory processes in AIH. Case-control study, steroid treatment

The change of mRNA expression in murine immortalized podocyte after miR-26a silencing

Project description:The change of mRNA expression in murine immortalized podocyte were analyzed after miR-26a silencing. These results provide a basical information of molecular pathology in podocyte biology. Mouse podocytes immortalized by temperature sensitive SV40 were used. Podocyte cultures grown at 33 °C were trypsinized and then cultured with RPMI-1640 without antibiotics in 24-well plates at 60–70% confluence for 2 days. On day 3, an anti-miR negative control (40 pmol) or the miR-26a miRNA inhibitor (40 pmol) was transfected to podocytes. The cells were analyzed after culturing for 24 hour.

miR-487b, miR-3963 and miR-6412 delayed myogenic differentiation in C2C12 mouse myoblast-derived cells.

Project description:We newly identified skeletal muscle differentiation-associated miRNAs by comparing miRNA expression profile between C2C12 cell and Wnt4-overexpressing C2C12 cell. miR-487b, miR-3963 and miR-6412 are significantly down-regulated in differentiating C2C12 cells, and transfection of their mimics resulted in reduced expression of myogenic differentiation markers including Troponin T, myosin heavy chain fast and slow type. Single analysis for each condition (proliferating C2C12 cells, differentiating C2C12 cells, proliferating Wnt4-overexpressing C2C12 subline cells

Gene expression profile of human cardiac fibroblasts (HCFs), induced cardiomyocytes (iCMs), and heart

Project description:Global gene expression profile of total 24460 probes in the iCMs. The gene expression shifts from a fibroblast state toward a cardiac-like phenotype by Gata4/Mef2c/Tbx5/Mesp1/Myocd (GMTMM) or GMTMM/miR-133 transduction at 7 days after transduction. MiR-133 silenced fibroblast signatures in parallel with cardiac gene activation, and Snai1 overexpression inhibited the effects of miR-133-mediated cardiac reprogramming. HCFs were used for negative control, human heart tissue for positive control. Gene expression profiles were compared among HCFs, iCMs and heart. 24460 probes were analyzed in each experiment.

HK2/AA Stimulation

Project description:Aristolochic acid nephropathy (AAN) is characterised by rapidly progressive tubulointerstitial nephritis culminating in end stage renal failure and urothelial malignancy. microRNAs (miRs) are small endogenous post-transcriptional regulators of gene expression implicated in numerous physiological and pathological processes. We aimed to characterise the mechanism of AA induced cell cycle arrest and its regulation by miRs. The microarray experiment was performed to identify differentially regulated microRNAs in human proximal tubulal epithelial cells treated with aristolochic acid (AA). Analysis or differential miR expression in human proximal tubular epithelial cell line (HK-2) treated with 5ug/ml aristolochic acid, control (n=3) vs aristolochic acid (n=3)
