Project description:Purpose: Understanding host-MAP interactions in initial stage of infection Methods: Native MAP and MDBK processed (4h) MAP were infected to bovine PBMCs. Total RNA after 24h and 72h were harvested. RNA-Seq was performed using total RNA of each group. Result: The gene expression patterns commonly activated in both groups suggest that Th17 activation is the main immunological response to MAP infection.
Project description:Global proteomics profiling of anaplastic large cell lymphoma cell lines DEL, SU-DHL-1 (ALK+), Mac-1, Mac-2A (ALK-) as well as Hodgkin lymphoma cell lines L-428, L-540, L-1236 and HDLM-2.
Project description:In order to further understanding the replication and pathogenesis of Caprine herpesvirus 1 (CpHV-1) and virus-host interactions. In this study, the proteomics of CpHV-1 infected Madin Darby bovine kidney (MDBK) cells was explored by using iTRAQ-LC-MS/MS technology.
Project description:We describe the NucleoATAC algorithm for high-resolution nucleosome positioning and occupancy determination using ATAC-seq. ATAC-seq was performed on Saccharomyces cerevisiae and Schizosaccaromyces pombe. Nucleosomes were called for both species as well as for the human GM12878 cell line using data from GSE47753. Additionally, ATAC-seq was performed on S. cerevisiae undergoing an osmotic stress time-course and nucleosomes were called for each time point.
Project description:Open chromatin regions were analyzed by ATAC-seq in MUTZ3 and MOLM1 cell lines (both inv(3) AML) to characterize the GATA2 super-enhancer region. ATAC-seq was performed as described (Buenrostro et al., 2013) with a modification in the lysis buffer to reduce mitochondrial DNA contamination.
Project description:SAGA and ATAC are two related transcriptional coactivator complexes, sharing the same histone acetyltransferase (HAT) subunit. The HAT activities of SAGA and ATAC are required for metazoan development but the precise role of the two complexes in RNA polymerase II transcription in mammals is less understood. To determine whether SAGA and ATAC have redundant or specific functions dependent on their HAT activities, we compared the effects of HAT inactivation in each complex with that of inactivation of either SAGA or ATAC core subunits in mouse embryonic stem cells (ESCs). We show that core subunits of SAGA or ATAC subunits are required for complex assembly, mouse ESC growth and self-renewal. Additionally, ATAC, but not SAGA subunits are required for ESC viability by regulating the transcription of translation-related genes. Surprisingly, depletion of specific or shared HAT module subunits caused a global decrease in histone H3K9 acetylation, but did not result in significant phenotypic or transcriptional defects. Thus, our results indicate that SAGA and ATAC are differentially required for viability and self-renewal of mouse ESCs by regulating transcription through different pathways, in a HAT-independent manner.
