Effects of SUV39H1 depletion on gene expression in HeLa cells

Project description:HeLa cells were transiently transfected with siRNA against SUV39H1, a histone H3K9 methyltransferase. Several genes were significantly up- or down-regulated. HeLa cells were transiently transfected with siRNA against SUV39H1 or negative control siRNA. Then total RNA was extracted.

Acetylated Histone Reader Brd4 functions as Repair Adaptor in Immunoglobulin Class Switch Recombination

Project description:Class Switch Recombination (CSR) is a B cell specific genomic alteration induced by activation induced cytidine deaminase (AID)-dependent DNA break, followed by repair and recombination at the immunoglobulin heavy-chain locus. The involvement of several chromatin-associated factors in promoting AID-induced DNA break formation has been reported. However, the involvement of chromatin adaptors at the repair phase of CSR remains unknown. Here, we provide evidence that acetylated histone reader Brd4 is critical to the repair and recombination step of CSR. Brd4 was recruited to the AID-induced DNA break region, and depletion of Brd4 from the S region chromatin by knockdown or a chemical inhibitor JQ1 causes CSR impairment without affecting AID-induced DNA break generation. Such inhibition of Brd4 suppressed the accumulation of 53BP1 and UNG at the cleaved S regions, perturbed switch donor-switch acceptor microhomology length and reduced Igh/c-myc translocation. We conclude that Brd4 serves as a histone-reader platform required for the recruitment of CSR repair components. Brd4 were depleted from the chromatin by either siRNA treatment or JQ1 (40nM) addition in CH12F3-2A cells in the presence of CIT stimulation. RNA from each samples were extracted and relative difference in transcript level were compared with control RNAi- and DMSO-treated, CIT-stimulated samples.

Analysis of therapeutic miRNA against KRAS mutant colorectal cancer

Project description:We compared the profile of miRNAs expressed in HEK293 and MRC5 cells that overexpressed KRASG12V to those expressed in parental cells that harbored wild-type KRAS. The results indicated that a subset of miRNAs was significantly down-regulated in KRASG12V transfected two cells. To address the functional relevance of miRNAs in KRAS mutant cancers, we transfected exogenous KRASG12V into HEK293 and MRC5 cells with wild type KRAS genes, and we comprehensively profiled the dysregulated miRNAs.

MicroRNA profile in hepatic epithelioid hemangioendothelioma

Project description:To elucidate the aetiology of HEH, especially with regard to microRNA (miRNA) profiles, samples obtained from three different parts of both normal and tumour tissues were analysed . The details of RNA extraction have been described in our previous reports. Interestingly, 16 miRNAs were significantly up-regulated and 51 miRNAs were down-regulated in the tumour tissues compared to the normal tissues (Studentâ??s t-test, p<0.01). In addition, unsupervised hierarchical clustering analysis using a Pearsonâ??s correlation showed that the tumour tissues clustered separately from the normal tissues. microRNA samples obtained from three different parts of both normal and tumour tissues were analysed

Gene expression profiling of processing glycosidase inhibitors: defining a common gene set produced by processing glycosidase inhibition in human cervical carcinoma HeLa cells

Project description:The objective of the present study is to investigate the role of processing glycosidase inhibition induced by processing glycosidase inhibitors, namely castanospermin as the processing glucosidases inhibitor, deoxymannojirimycin as the processing mannosidases inhibitor, and deoxyfuconojirimycin as the fucosidase inhibitor. Comparative gene expression analysis was performed in human cervical carcinoma HeLa cells, with non-inhibitor-treated cells as the negative control. Gene expression was analyzed using 3D-GeneÂ® Human 25k oligonucleotide microarrays and computational gene expression analysis tools. Inhibition of processing glycosidases (glucosidases, mannosidases, and fucosidase) in human cervical carcinoma HeLa cells was performed by treating with a small molecule inhibitor and then culturing at 37Â°C. Total RNA samples were prepared from the cells. Gene expression was analyzed using 3D-GeneÂ® Human 25k oligonucleotide microarrays. Sample preparation for array hybridization was carried out as described in the manufacturer's instructions.
