Description
We investigated the clinical, histopathologic and genomic features of donor-specific antibody (DSA) +/C4d- and DSA-/C4d- transplant glomerulopathy (TGP) using microarrays. Comparison of the gene expression profiles of DSA-/C4d- TGP biopsies with ptc+g score > 1 to normal and IFTA (Interstitial Fibrosis and Tubular Atrophy) biopsies by microarrays revealed increased expression of quantitative cytotoxic T cell--associated transcripts (QCAT). However, CAMR (chronic antibody-mediated rejection) and DSA+/C4d- TGP had increased expression of QCAT, interferon-gamma and rejection induced, constitutive macrophage-associated, natural killer cell-associated, and DSA selective transcripts. B cell and endothelial cell associated transcripts expression were upregulated only in CAMR biopsies. Our results suggest that while DSA+/C4d- TGP should be classified under CAMR, DSA-/C4d- TGP with ptc+g score > 1 probably develops through a chronic cellular immune response.

Description
wt1a:GFP labels a population of subepicardial cells in the uninjured ventricle. Here we compare the expression profile of wt1a:GFP-positive cells to the rest of the cells of the ventricle. Overall design: Four paired biological replicates of wt1a:GFP-positive and wt1a:GFP-negative cells obtained from pools of 3-5 zebrafish heart ventricles.

Description
Contrary to mammals, zebrafish regenerate their heart upon cryoinjury of the cardiac ventricular apex. Regeneration is preceed by a fibrotic response. To understand the contribution of different cell sources to zebrafish cardiac fibrosis we performed an RNASeq including endocardial kdrl:mCherry cells from an uninjured heart, and activated endocardial kdrl:mCherry cells, postnb:citrine fibroblasts and the rest of the cells at 7 days post injury. Overall design: Three to six biological replicates consisting of different cell types obtained from the ventricular apex.

Description
Contrary to mammals, zebrafish regenerate their heart upon cryoinjury of the ventricular apex. Regeneration is preceeded by a transient fibrotic response. Here we compare the expression profile of fibroblast-like cells at 7 different time points of fibrosis resolution. Using a postnb:CreERT2; ubb:loxP-GFP-loxP-mCherrycz1701 double transgenic line, we permanently label cells that expressed postnb at 3 and 4 days post injury (dpi) with mCherry by administration of 4-OHT. We sequenced mCherry-labelled cells obtained from the ventricular apex at 7 and 60 dpi. Overall design: postnb-derived cells were FAC sorted from a pool of three to five biological samples. Four pools were collected at 7 dpi and three at 60 dpi. RNA was extracted from those pools and further processed for transcriptome analysis.

Description
The presence of Donor-Specific anti-HLA Antibodies (DSA) is associated with an increased risk of both acute and chronic antibody-mediated rejection (AMR) in kidney allografts. AMR has remained challenging in kidney transplantation and is the major cause of late allograft loss. However, not all patients with DSA develop AMR, leading to the question of whether this represents accommodation, if other protective mechanisms exist or if this is actually a state of pre-rejection.

- Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
Global energy balance in mammals is controlled by the actions of circulating hormones that coordinate fuel production and utilization in metabolically active tissues. Bone-derived osteocalcin, in its undercarboxylated, hormonal form, regulates fat deposition and is a potent insulin secretagogue. Here, we show that insulin receptor (IR) signaling in osteoblasts controls osteoblast development and osteocalcin expression by suppressing the Runx2 inhibitor Twist-2. Mice lacking IR in osteoblasts have low circulating undercarboxylated osteocalcin and reduced bone acquisition due to decreased bone formation and deficient numbers of osteoblasts. With age, these mice develop marked peripheral adiposity and hyperglycemia accompanied by severe glucose intolerance and insulin resistance. The metabolic abnormalities in these mice are improved by infusion of exogenous under-carboxylated osteocalcin. These results indicate the existence of a bone-pancreas endocrine loop through which insulin signaling in the osteoblast ensures osteoblast differentiation and stimulates osteocalcin production, which in turn regulates insulin sensitivity and pancreatic insulin secretion to control glucose homeostasis.
