View SamplesWe used RNA-Seq to detail the global expression changes induced when SWELL1 is genetically deleted from adipocytes. Overall design: We generated isogenic SWELL1 KO adipocyte cell lines from 3T3-F442A cells. CRISR/Cas9 was used to knockout the SWELL1 gene in the parental 3T3-F442A line. These cell lines were grown in culture and RNA was extracted for sequencing. RNA was sequenced on an Illumina Hi-Seq at the University of Iowa Core Facility.
SWELL1 is a regulator of adipocyte size, insulin signalling and glucose homeostasis.

View SamplesThe brain renin-angiotensin system (RAS) stimulates resting metabolic rate in part through a mechanism involving suppression of the circulating RAS. This effect appears to be mediated through a reduction in angiotensin AT2 receptor (AT2R) signaling within inguinal fat. To examine the molecular mechanisms underlying this effect, mice with hyperactivity of the brain RAS (“sRA” mice, expressing human renin via the synapsin promoter and human angiotensinogen via its own promoter) and littermate controls were chronically infused with vehicle or the AT2R specific agonist, CGP-42112a (CGP, 90 ng/hr, 8 wk, sc). To identify altered signaling pathways, total RNA was isolated from inguinal adipose tissue and transcript abundance was quantitated by RNA-Seq. Overall design: Four groups of mice were studied: controls receiving either a saline infusion (CON) or a specific angiotensin type 2 receptor agonist (CON_CGP), transgenic mice with specific activation of the brain renin-angiotensin receiving either a saline infusion (SRA) or a specific angiotensin type 2 receptor agonist (SRA_CGP). A sample size of N=3-4 was used for each of the four groups.

View SamplesThe vascular endothelial growth factor A (VEGF) is involved in various physiological processes such as angiogenesis or wound healing but is also crucial in pathological events such as tumor growth. Thus, clinical anti-VEGF treatments have been developed which could already prove to have enormous beneficial effects for cancer patients. In this article we describe the first VEGF-derived CD8+ T-cell epitope. The natural HLA ligand SRFGGAVVR was identified by differential mass spectrometry in two primary renal cell carcinomas (RCC) and was significantly over-presented on both tumor tissues. SRFGGAVVR is derived from a cryptic translated region of VEGF presumably by initiation of translation at the non-classical start codon CUG499. SRFGGAVVR specific T-cells were generated in vitro using peptide loaded dendritic cells or artificial antigen presenting cells. They were identified by HLA tetramer analysis after in vitro stimulation. SRFGGAVVR specific CD8+ T-cells were fully functional T-effector cells, which were able to secrete IFN-gamma upon stimulation and killed tumor cells in vitro. Additionally, we have quantitatively analyzed VEGF mRNA and protein levels in RCC tumor and normal tissue samples by gene chip analysis, qRT-PCR, in situ hybridization, and bead based immuno assay. In the future, T-cells directed against VEGF as a tumor associated antigen may represent a possible way of combining peptide-based anti-VEGF immunotherapy with already existent anti-VEGF cancer therapies.

View SamplesBackground: Immunoadsorption with subsequent IgG substitution (IA/IgG) represents a novel therapeutic approach in treatment of dilated cardiomyopathy (DCM) which leads to improvement of left ventricular ejection fraction (LVEF). However, response to this therapeutic intervention shows wide inter-individual variability. In this pilot study, we tested the value of clinical, biochemical and molecular parameters for prediction of the response of patients with DCM to IA/IgG.

View SamplesThe oncogenic mechanisms and tumour biology underpinning Clear Cell Sarcoma of Kidney (CCSK), the second commonest paediatric renal malignancy, are poorly understood and currently therapy depends heavily on Doxorubicin with cardiotoxic side-effects. Previously, we characterised the balanced t(10;17)(q22;p13) chromosomal translocation, identified at that time as the only recurrent genetic aberration in CCSK. This translocation results in an in-frame fusion of the YWHAE (encoding 14-3-3e) and NUTM2 genes, with a somatic incidence of 12%. Clinico-pathological features of that cohort suggested that this aberration might be associated with higher stage and grade disease. Since no primary CCSK cell line exists, we generated various stably transfected cell lines containing doxycycline-inducible HA-tagged-YWHAE-NUTM2, in order to study the effect of expressing this transcript. 14-3-3e-NUTM2-expressing cells exhibited significantly greater cell migration compared to mock-treated controls. Gene and protein expression studies conducted in parallel on this model system suggested dysregulation of signalling pathways as a basis to the migration changes. Importantly, by blocking these signalling pathways using anti-EGFR, anti-IGF1R and anti-PDGFa neutralising antibodies, the migratory advantage conferred by transcript expression was abrogated. These results support 14-3-3e-NUTM2 expression as a contributor to CCSK tumorigenesis and provide avenues for the exploration of novel therapeutic approaches in CCSK.
