Description
OVE26 (OVE) mice provide a useful model of advanced diabetic nephropathy (DN) with respect to albuminuria and pathologies. We showed that albuminuria, reduced GFR and interstitial fibrosis, which normally take 8-9 months to develop, are more advanced in uninephrectomized OVE mice within 10 weeks of surgery, at 4.5 months of age. The accelerated progression of renal damage, especially renal fibrosis in OVE-uni mice, was also identified at the gene expression level. The hepatic fibrosis/hepatic stellate cell activation pathway was by far the most significant Ingenuity canonical pathway identified by gene array in OVE-uni mice. Many inflammatory- and immune-related pathways were found among the top pathways up-regulated in OVE-uni kidneys, including acute-phase response signaling, leukocyte extravasation, IL6, IL10, IL12 signaling, TREM1 signaling, dendritic cell maturation and the complement system. These pathways were also dramatically up-regulated in 8-month-old OVE mice (GSE20636). Nephrectomized OVE mice are a much faster alternative model for studying advanced renal disease in diabetes.

Description
T cell development relies on the precise developmental control of various cellular functions for appropriate positive and negative selection. Previously, gene expression profiling of peptide-driven negative selection events in the N15 TCR class I MHC-restricted mouse and D011.10 TCR class II MHC-restricted mouse has offered insights into the coordinate engagement of biological processes affecting thymocyte development. However, there has been little comparable detailed in vivo global genome expression analysis reported for positive selection.

Description
Hopx appears to be needed for persistence of Th1 effector memory cells. IFN-gamma-producing Th cells are significantly reduced in Hopx-deficient mice compared to Hopx-expressing littermates and Hopx-deficient Th1 cells show a defective persistence upon adoptive transfer. Moreover, Hopx protects Th1 cells from Fas-mediated cell death in vitro. To further dissect the role of Hopx and to identify target genes of Hopx, we have performed transcriptome analysis to compare gene expression in Hopx-deficient versus Hopx-competent Th1 cells. In agreement with the role of Hopx in supporting survival of Th1 effector memory cells, anti-apoptotic cells were up-regulated and pro-apoptotic genes were down-regulated in Hopx-competent compared to Hopx-deficient Th1 cells.
Publication Title
Persistence of effector memory Th1 cells is regulated by Hopx.
