Development of gene expression signatures on immunity for bursal peptide BSP-II

ABSTRACT: To further elucidate the mechanism of BSP-II on immunity on the broad molecular level, we have employed whole genome microarray expression profiling as a discovery platform to examine gene expression patterns during BSP-II treatment in a mouse derived hybridoma culture system. Hybridoma cell was treated ex vivo, and robust normalization of the data identified 1279 differentially expressed probe sets exhibiting minimum 1.5-fold changes that distinguished between BSP-II and control samples. Various pathwayswere significantly impacted by BSP-II treatment, and gene Ontology annotations show changes in the expression of molecules involved in immune and immunocyte related cellular processes. Expression of nine genes (MS4A2, CD3D, FGF21, CD80, PTPRC, NFATC4, IL2RB, Fas and LAT) from this signature was quantified in the RNA samples by QRT-PCR, confirming low variability between the predicted response patterns.

BSP-II induced gene expression in hybridoma cell was measured at 4 hours after exposure to doses of 0ug/ml and 5ug/ml. Two independent experiments were performed using different cells for each experiment.

Development of gene expression signatures on immunity for bursal peptide BPP-II

Project description:To further elucidate the mechanism of BPP-II on immunity on the broad molecular level, we have employed whole genome microarray expression profiling as a discovery platform to examine gene expression patterns during BPP-II treatment in a mouse derived hybridoma culture system. Hybridoma cell was treated ex vivo, and robust normalization of the data identified 2478 differentially expressed probe sets exhibiting minimum 1.5-fold changes that distinguished between BPP-II and control samples. Various pathwayswere significantly impacted by BPP-II treatment, and gene Ontology annotations show changes in the expression of molecules involved in immune and immunocyte related cellular processes. Expression of 8 genes (MS4A2，CD86，CD80， Fas，CDKN2A，CBLC, FGF21 and Fyn) from this signature was quantified in the RNA samples by QRT-PCR, confirming low variability between the predicted response patterns.

Profile of gene expression signatures on DT40 cell for bursal-derived peptides

Project description:To further elucidate the mechanism of bursal-derived bioactive peptides on avian B cell proliferation on the broad molecular level, we have employed whole genome microarray expression profiling as a discovery platform to examine gene expression patterns during BP5 and BSP-II treatment in DT40 cell culture system. Analysis of our expression microarray data in this manner defined 3163 genes up-regulated and 3539 genes down-regulated by BP5 treatment and 3117 genes up-regulated and 3531 genes down-regulated by BSP-II treatment at 95% confidence, with a commonly regulated gene set of 2253 upregulated genes and 2083 downregulated genes. Various pathways were significantly impacted by BP5 and BSP-II treatment, and gene Ontology annotations show changes in the expression of molecules involved in DT40 cell with BP5 and BSP-II treatment. Expression of 12 genes (FGF3, RAP1B, TCEB1, CSNK2A1, DNMT1, HIF1A, HDAC1, FZR1, GDF3, FGF8, IRF7, and SKP1) from this signature was quantified in the RNA samples by QRT-PCR, confirming low variability between the predicted response patterns.

The role of NFATc4 on aldosterone production in NCI-H295R human adrenocortical cell line

Project description:To investigate the role of NFATc4 in aldosterone production, we created NFATc4 knock-out NCI-H295R cell line and overexpressed active NFATc4 in wild type NCI-H295R cells. We then analyzed the transcriptome of the four cell types.

Photoperiod associated genes in the poplar bark

Project description:The role of bark storage proteins (BSPs) in seasonal N storage and cycling has been well documented. However, the regulatory mechanisms and pathways associated with this physiological process are poorly understood. The objective of this study is to investigate global patterns of gene expression associated with photoperiod regulated BSP accumulation and to identify candidate genes, pathways and regulatory factors governing N storage and cycling in poplar. In this study, differential expression of protease inhibitors, proteases, transcription factors, and other genes coincided with increased BSP gene expression, suggesting a complex regulatory network that might play an important role in BSP accumulation.
