Project description:Illumina microarray analysis of primary human B cell and peripheral blood mononuclear cell (PBMC) co-cultures stimulated with anti-IgM and superantigens for 3 days (BT) compared to the same co-cultures without stimualtion (BTNo). Total RNA was extracted from co-cultures after 3 days in the presence or absence of stimulation with anti-IgM and superantigens.

Project description:The goal of this study is to investigate the secretion from human colorectal adenocarcinoma cell, which effect to peripheral blood mononuclear cell (PBMC). Genome wide DNA methylation profiling of co-cultured PBMC without human colorectal adenocarcinoma cell lines and co-cultured PBMC with human colorectal adenocarcinoma cell lines were generated datas by microarray technology. The Illumina Infinium MethylationEPIC BeadChip was used to obtain DNA methylation profiles across approximately 850,000 CpGs in enhancer regions, gene bodies, promoters and CpG islands. Samples included duplicate PBMC of female control, duplicate PBMC of male control, duplicate PBMC of female were co-cultured with HT29, and duplicate PBMC of male were co-cultured with SW480.

Project description:Breast cancer cells reprogram the oncogenic lncRNAs/mRNAs co-expression networks in three- dimensional microenvironment To have a more functional approach, organotypic 3D cell cultures that more accurately mimic the characteristics of solid tumors in vivo and the tumor microenvironment are required. In this study, DNA microarrays were employed to deline the changes in lncRNAs expression patterns of breast cancer cells, cultured in 3D and 2D conditions from BT-474 cell line. Furthermore, potential lncRNAs/mRNAs pairs co-expressed in 3D cultures exhibit a high degree of similarity with those found in luminal B breast cancer patients suggesting that they could be adequate pre-clinical tools to identify, not only biomarkers related to endocrine therapy response and PCR, but to understand the biological behavior of cancer cells in 3D microenvironments, which point towards an important contribution of the roles of lncRNAs in organotypic 3D cultures.

Project description:The species Staphylococcus (S.) aureus harbors 19 superantigen gene loci, six of which are located in the enterotoxin gene cluster (egc). While these egc superantigens are far more prevalent in clinical S. aureus isolates than non-egc superantigens, they are not a prominent cause of toxic shock. Moreover, neutralizing antibodies against egc superantigens are very rare, even among carriers of egc-positive S. aureus strains. In search of an explanation we have tested two non-exclusive hypotheses: 1) egc and non-egc superantigens have unique intrinsic properties and drive the immune system into different directions; 2) egc and non-egc-superantigens are released by S. aureus under different conditions, which shape the immune response. A comparison of three egc (SEI, SElM and SElO) and three non-egc superantigens (SEB, SElQ, TSST-1) revealed that both induced proliferation of human PBMC with comparable potency and elicited similar Th1/Th2-cytokine signatures. This was supported by gene expression analysis of PBMC stimulated with one representative superantigen from each group (SEI and SEB). They induced very similar transcriptional changes, especially of inflammation-associated gene networks, corresponding to a very strong Th1- and Th17-dominated immune response. In contrast, the regulation of superantigen release differed markedly between both superantigen groups. Egc-encoded proteins were secreted by S. aureus during exponential growth, while non-egc superantigens were released in the stationary phase. We conclude that the distinct biological behavior of egc and non-egc superantigens is not due to their intrinsic properties, which are very similar, but caused by their differential release by S. aureus.

Experiment Overall Design: PBMCs from 3 healthy blood donors were purified and treated with Medium (control) and recombinant staphylococcal superantigens SEB and SEI. After 6 hours of treatment, total RNA was extracted and hybridized to Affymetrix GeneChip Arrays.

Project description:Glycosylation represents a major post-translational modification of proteins that can influence their structure and function.Telesot immunoglobulin M (IgM) is an especially important product of the immune system because it is the main Abs in seum and plays a critical role against defense infection. However, little is known regarding site-specific N-glycan characteristics in teleost IgM , LC-ESI-MS/MS was used to analysis deglycopeptides and glycopeptides of grass carp serum IgM, and MALDI-MS was used to analysis released carbohydrates by PNGaseF diestion of grass carp serum IgM.

Project description:Waldenström macroglobulinemia (WM), is a rare non-Hodgkin lymphoma preceded by a clinically asymptomatic benign monoclonal gammopathy of undetermined significance (IgM-MGUS). The factors underlying the malignant progression between these two IgM-monoclonal gammopathies remain poorly understood. The non-coding genome is increasingly recognized as an important driver of disease pathogenesis, and there remains a lack of exploration of the influence of non-coding RNAs within the IgM-monoclonal gammopathy disease spectrum. The present study explores the role of microRNA (miRNA) and long non-coded RNA (lncRNA) in IgM-gammopathies and specifically elucidates potentially regulated protein-coding genes and pathways. A comprehensive analysis of miRNA, lncRNA and protein-coding coding genes was conducted on 28 subjects, 17 patients with WM, 6 patients with IgM-MGUS, and 5 normal controls. Differential expression analysis revealed a number of dysregulated miRNA and lncRNA between IgM-gammopathies compared to normal controls and specifically between IgM-MGUS and WM. Pathway analysis was conducted utilizing differentially expressed mRNA with correlated biological expression of targeting miRNA. Here, a number of pathways were implicated influencing a gamut of cellular functions, including cell signaling, metabolism, replication, and immune regulation in both WM compared to IgM-MGUS and IgM-gammopathies compared to controls. This report is additionally one of the first published analyses of lncRNAs in WM, where we demonstrate a number of lncRNA associated with transcription and apoptosis regulation genes in WM compared to IgM-MGUS. This study highlights the role of non-coding RNA in IgM-gammopathies and the potential to recognize novel targets which may halt or slow the malignant progression between these two diseases.
