Expression data from RKO cells transfected with SPARCL1 and vector control

Project description:Colon cancer cell line RKO grown on Matrigel form a luminal-like structure after the transfection of SPARCL1 gene, which may imply the differentiation of the cells. To indentify genes regulated by SPARCL1, we built two stable cell lines: RKO with pLXSN-SPARCL1 plasmid (RKO-SPARCL1) and RKO with pLXSN plasmid (RKO-pLXSN). Then we cultured these two cell lines on both plastic dish and dish cover with a layer of Matrigel. We used microarrays to undentify global gene expression change in RKO cells after the tranfection of SPARCL1. Four samples including RKO-pLXSN cells cultured on plastic, RKO-pLXSN cells cultured on Matrigel, RKO-SPARCL1 cells cultured on plastic and RKO-SPARCL1 cells cultured on Matrigel were trypsinized and collected for RNA extraction and hybridization on Affymetrix microarray U133plus2.0. Supplementary files: * RLvsRP: up and down regulated genes comparing with RKO-SPARCL1(RL) and RKO-pLXSN(RP) cells cultured on plastic * RLMvsRPM: up and down regulated genes comparing with RKO-SPARCL1(RL) and RKO-pLXSN(RP) cells cultured on Matrigel

Coordinated Chromatin Remodeling induced by Demethylation requires SRCAP mediated H2A.Z exchange [Methylation]

Project description:Genome wide DNA methylation profiling of RKO cells with combination treatments of non-target siRNA or SRCAP siRNA and PBS or 1uM 5-Aza-CdR treatment. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across 27,578 CpGs in treated RKO cells. Samples included cells under 4 different treatments. The sample treated with non target siRNA and PBS serves as control sample. Bisulphite converted DNA from the 4 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip v1.2

DNMT3B targets in RKO cells by ChIP-on-chip

Project description:Chromatin immunoprecipitation with DNMT3B specific antibody followed by CGI microarray identified genes with or without CGIs, repeat elements and genomic contigs in RKO cells. ChIP-Chop analysis showed that majority of the target genes including P16, DCC, DISC1, SLIT1, CAVEOLIN1, TBX5, TBX18, HOXB13 and some histone variants, that harbor CGI in their promoters, were methylated in multiple colon cancer cell lines but not in normal colon epithelial cells. Further, these genes were reactivated in RKO cells after treatment with 5-aza-2â-deoxycytidine, a DNA hypomethylating agent. COBRA and bisulfite genomic sequencing showed that the CGIs encompassing the transcription start sites (TSS) of DCC, TBX5, TBX18, SLIT1 were also methylated in primary colorectal tumors compared to matching normal tissues whereas GNA11 was methylated in both. MassARRAY analysis demonstrated that the CGI located ~4.5 kb upstream of HOXB13 +1 site was tumor-specifically hypermethylated in primary colorectal cancers and cancer cell lines. Analysis of tumor suppressor properties of two aberrantly methylated transcription factors, HOXB13 and TBX18, revealed that both inhibited growth and clonogenic survival of colon cancer cells in vitro, but only HOXB13 abolished tumor growth in nude mice. Chromatin immunoprecipitation with DNMT3B specific antibody in RKO cells was compared to control antibody.

Arginine sensing in Leishmania

Project description:Abstract Protozoa of the genus Leishmania are the causative agents of leishmaniasis in humans. These parasites cycle between promastigotes in the sand fly mid-gut and amastigotes in phagolysosome of mammalian macrophages. During infection, they up-regulate host nitric oxide synthase and arginase expression, both of which use arginine as a substrate. These elevated activities deplete macrophage arginine pools, a situation that invading Leishmania must overcome since it is an essential amino acid. Leishmania donovani imports exogenous arginine via a mono-specific amino acid transporter (AAP3) and utilizes it primarily through the polyamine pathway to provide precursors for trypanothione biosynthesis. Here we report the discovery of a pathway whereby promastigote and amastigote forms of the Leishmania sense the lack of environmental arginine and respond with rapid up-regulation in AAP3 expression and activity, as well as several other transporters. Significantly, this arginine deprivation response is also activated in parasites during macrophage infection. Phosphoproteomic analyses of L. donovani promastigotes have implicated a mitogen activated protein kinase 2 (MPK2)-mediated signaling cascade in this response and L. mexicana mutants lacking MPK2 are unable to respond to arginine deprivation. In addition, these mutants cannot differentiate into amastigotes in axenic culture or in peritoneal macrophages, and fail to establish an infection in mice. We propose that sensing arginine levels plays a critical role in Leishmania virulence by activating a rapid metabolic reaction for salvaging this amino acid in response to the lower arginine concentration in the macrophage phagolysosome.
