Project description:HCC cell line SMMC-7721 were treatment with human recombinant artemin for 12 hours. Total RNA was extracted and the induced gene expression was analyzed. Analysis of gene expression induced by artemin treatment
Project description:lncRNA-ATB induced transcriptional changes in SMMC-7721 Two-condition experiment, control (pcDNA3.1) vs lncRNA-ATB expression (pcDNA3.1-ATB). Each has 3 biological repeats.
Project description:In our present study, we found that lncRNA-hPVT1 could promote HCC cell proliferation. We want to know what were the target genes of lncRNA-hPVT1. So we constructed the hPVT1-overexpressed SMMC-771 cells and observed the mRNA profile in hPVT1-overexpressed and control SMMC-771 cells. lncRNA-hPVT1 induced transcriptional changes in SMMC-7721. Two-condition experiment, control (LV-Control) vs lncRNA-hPVT1 expression (LV-hPVT1 Clone2 ). Each has 3 biological repeats.
Project description:To gain insights into the mechanisms of Eupolyphaga sinensis Walker (ESW) and taspine derivate on inhibition to HCC, we have employed whole genome microarray expression profiling as a discovery platform to identify different genes between ESW-treated sample and control. At the same time, the differences were investigated between taspine derivate and the same control. SMMC-7721 cells were cultivated in the absence or presence of 0.1mg/mL ESWE and Taspine derivate of 2.5x10-5mol/L for 48 h, followed by the Agilent Whole Human Genome Oligo Microarray. The PLG, PKCM-NM-2 and IL3RA genes confirmation of Microarray analysis was confirmed by Real-time PCR. SMMC-7721 cells were cultivated in the absence or presence of 0.1mg/mL Eupolyphaga sinensis Walker extract (ESWE) and Taspine derivate of 2.5x10-5mol/L for 48 h, followed by the Agilent Whole Human Genome Oligo Microarray
Project description:The whole human genome microarray was used for analysis of the differentially expressed genes in SMMC-7721 cells when exposed to 1 μM IMB5043 treatment for 24 h.
Project description:Hepatocellular carcinoma (HCC) ranks sixth among the most common malignancies and fourth in mortality among all kinds of cancers in the world. Recent advances in early diagnosis and therapeutics have led to improved survival of HCC patients, but the recurrence and metastasis are still main reasons for the poor prognosis and high mortality of HCC. Many researches on the mechanism of HCC deterioration have uncovered the epithelial-mesenchymal transition (EMT) as a major trigger for HCC metastasis and invasion.In this study, in order to systematically investigate the dynamic site-specific glycosylation alterations associated with the EMT process of HCC, two hepatoma cell lines SMMC-7721 and HepG2 were treated using HGF and the cell proteins were harvested at six treatment time points. Using TMT-labeling, solid phase extraction and mass spectrometry, we not only detailly profiled N-glycoproteome of both cell lines at site-specific glycosylation level, but also dynamically quantified those intact glycopeptides among six increasing HGF-treated time points. By dynamically quantifying enriched glycopeptides and proteins among six HGF-treated time points in two cell lines, we identified 20 up-regulated intact glycopeptides during the process of EMT, with the majority changed at the glycosylation level instead of protein expression level. The site-specific glycosylation change of those glycoproteins was related to the process of EMT, which was further verified by a series of molecular biology methods, mass spectrometry, and migration and invasion assay in vitro.
Project description:The role of TGF-M-NM-2-induced epithelial-mesenchymal transition (EMT) in cancer cell dissemination is well established, but the involvement of lncRNAs in TGF-M-NM-2 signaling is still unknown. In this study, we observed that the lncRNA-Activated by TGF-M-NM-2 (lncRNA-ATB) was upregulated in hepatocellular carcinoma (HCC) metastases and associated with poor prognosis. lncRNA-ATB promotes the invasion-metastasis cascade, which suggest that lncRNA-ATB, a mediator of TGF-M-NM-2 signaling, could predispose HCC patients to metastases and may serve as a potential target for anti-metastatic therapies. SMMC-7721 hepatoma cells were continuously treated with 10 ng/ml of recombinant TGF-M-NM-21 for 21 days. Total RNA recovered from three untreated cells and three treated cells were used to acquire different expression profiles of mRNAs and lncRNAs.
