In preclinical models, α-difluoromethylornithine (DFMO), an ornithine decarboxylase (ODC) inhibitor, delays the onset of type 1 diabetes (T1D) by reducing β cell stress. However, the mechanism of DFMO action and its human tolerability remain unclear. In this study, we show that mice with β cell ODC deletion are protected against toxin-induced diabetes, suggesting a cell-autonomous role of ODC during β cell stress. In a randomized controlled trial (ClinicalTrials.gov: NCT02384889) involving 41 re ...[more]

High-throughput proteomics and phosphoproteomics of rat tissues using micro-flow Zeno SWATH

Project description:We investigated the combined sensitivity of micro-flow liquid chromatography with a ZenoTOF mass spectrometer for high throughput proteomic and phosphoproteomic analysis of rat tissues. Comparing the proteomes acquired using data-independent acquisition (DIA) on the ZenoTOF 7600 with the previous generation TripleTOF 6600, more proteins were quantified using a fifth of the sample load and a third of the instrument time. Zeno SWATH data was evaluated using replicate injections of rat organ digests to compare FragPipe and DIA-NN computational pipelines. FragPipe identified more proteins in 7 of the 8 rat organs, with an extra 12% and 17% observed in heart and muscle tissue respectively. The number of identified peptides per protein were higher with FragPipe and the precision of missing values across replicate injections was more consistent. Single-shot phosphopeptide enrichment from 100 µg rat tissue, without fractionation, was acquired using data-dependent acquisition (DDA) on both instruments. A total of 5,108 phosphosites were quantified with a negligible increase in phosphosites found using the ZenoTOF 7600 relative to the 6600. Using DIA on the ZenoTOF, 8,013 phosphosites were quantified using Spectronaut.

CMPF alters expression of genes related to metabolism in isolated mouse islets

Project description:CMPF is elevated in diabetes and is associated with impaired insulin secretion. We used microarrays to determine the effect of CMPF on gene expression in isolated islets. Isolated islets from male CD1 mice were treated for 24h with vehicle control or 200uM CMPF.

A Protease Activatable Interleukin-2 Fusion Protein Engenders Antitumor Immune Responses by Interferon Gamma-Dependent and Interferon Gamma-Independent Mechanisms.

Project description:Cytokines are powerful mediators of immune responses and some, such as interleukin-2 (IL-2), have achieved dramatic responses as cancer immunotherapies. Unfortunately, systemic administration often results in deleterious side effects, prompting exploration of strategies to localize cytokine activity to the tumor microenvironment (TME). To this end, we constructed an IL-2/IL2Ra fusion protein (IL-2FP) with an MMP2/9-specific cleavage site, designed to exploit the dysregulated protease activity in the TME to selectively activate IL-2 in the tumor. To determine if TME protease activity is sufficient to cleave the FP and if FP activity is due to specific cleavage, we created Colon 38 tumor cell lines expressing similar levels of IL-2FPs with either a functional cleavage site [H11(cs-1FP)] or a scrambled, noncleavable sequence [H2(scramFP)]. H11(cs-1FP) tumors demonstrated reduced tumor growth, characterized by regressions not observed in H2(scramFP) tumors. Analysis through qRT-PCR, flow cytometry, and immunohistochemistry indicate robust CD8 responses in the H11(cs-1FP) tumors. Interferon gamma (IFNg) knockout mice revealed that the immune effects of the cleavable FP are mediated through both IFNg-dependent and IFNg-independent mechanisms. Collectively, these data suggest that matrix metalloproteinases (MMPs) in the TME can cleave the IL-2FP specifically, thus enhancing an antitumor response, and provide a rationale for further developing this approach.

Interleukin-10 causes interferon-γ-dependent emergency myelopoiesis

Project description:In emergency myelopoiesis (EM), expansion of the myeloid progenitor compartment and increased myeloid cell production is observed, often mediated by the pro-inflammatory cytokine IFN-γ. IL-10 inhibits IFN-γ secretion, largely by its effects on macrophages and dendritic cells, but, paradoxically, its therapeutic administration to humans causes hematologic changes similar to those observed in EM. In this work we used different in vivo systems, including a humanized immune system mouse model, to show that IL-10 triggers EM, with a significant expansion of the myeloid progenitor compartment and production of myeloid cells. Hematopoietic progenitors display a prominent IFN-γ transcriptional signature, and we show that IFN-γ mediates IL-10-driven EM. We also found that IL-10, unexpectedly, induces IFN-γ production by all T cell subsets in vivo. Therefore, in addition to its established anti-inflammatory properties, IL-10 can induce IFN-γ production and EM, opening new perspectives for the design of IL-10-based immunotherapies.

Apoptosis rate and transcriptional response of pancreatic islets exposed to the PPAR gamma agonist Pioglitazone

Project description:To explore the molecular pathways underlying thiazolidinediones effects on pancreatic islets in conditions mimicking normo- and hyperglycemia, apoptosis rate and transcriptional response to Pioglitazone at both physiological and supraphysiological glucose concentrations were evaluated. Adult rat islets were cultured at physiological (5.6 mM) and supraphysiological (23 mM) glucose concentrations in presence of 10 mM Pioglitazone or vehicle. RNA expression profiling was evaluated with the PancChip 13k cDNA microarray after 24-h, and expression results for some selected genes were validated by qRT-PCR.

Human islets exposed to cytokines IL-1β and IFN-γ

Project description:In the context of T1 Diabetes, pro-inflammatory cytokines IL-1β and IFN-γ are known to contribute to β-cell apoptosis; The measurement of mRNA expression following β-cell exposure to these cytokines gives a picture of the changes in gene expression characterizing the path to β-cell dysfunction and death. Human islets were isolated and exposed (or not) to IL-1β and IFN-γ. The samples were collected at various time points for profiling with Affymetrix arrays. These measurements were performed three times.

Association of interleukin 2, interleukin 12, and interferon-γ with intervertebral disc degeneration in Iranian population.

Project description:BACKGROUND:Intervertebral disc degeneration (IVDD) is an age-related degenerative disease, presenting with low back pain or radicular pain. The inflammatory changes would occur in discs in the process of IVDD. Therefore, the inflammatory and anti-inflammatory cytokines, as well as their respective genes, have been proposed to play roles in pathophysiology of disease. This study has been conducted to elucidate the role of IL-2, IL-12, and IFN-γ single nucleotide polymorphisms (SNP) in this disease. METHOD:Seventy-six patients who were diagnosed with IVDD and 140 healthy controls who complied with eligibility criteria were included. A total volume of 5 cc peripheral blood was obtained from each participant to investigate the IL-2 + 166G/T, IL-2 -330G/T, IL-12 - 1188A/C, and IFN-γ +847A/T SNPs through PCR-SSP method. RESULTS:The 'TG' and 'TT' genotypes of IL-2 - 330G/T polymorphism were significantly more common among patients and healthy controls respectively. The 'GT' and 'TT' haplotypes of IL-2 (comprised of -330G/T, and + 166G/T SNPs) were also more common among patients and controls respectively. CONCLUSION:This study indicated the significant role of IL-2 genotypes and haplotypes in IVDD. These SNPs were differently distributed in patients and controls. Therefore, alteration in the structure of IL-2 gene could play an important role in pathophysiology of IVDD.
