Project description:Organ transplant recipients (OTRs) on Cyclosporine A (CSA) are prone to catastrophic cutaneous squamous cell carcinoma (SCC). Allograft-sparing, cancer-targeting systemic treatments are unavailable. We have shown increased risk for catastrophic SCC in OTRs via CSA-mediated induction of Interleukin-22 (IL-22). Herein, we found CSA drives SCC proliferation and tumor growth through IL-22 and JAK/STAT pathway induction. We in turn inhibited SCC growth with an FDA-approved JAK 1/2 inhibitor, Ruxolitinib. In human SCC cells, greatest proliferative response to IL-22 and CSA treatment occurred in non-metastasizing lines. IL-22 treatment upregulated JAK1 and STAT1/3 in A431 SCC cells. JAK/STAT pathway genes were highly expressed in tumors from a cohort of CSA-exposed OTRs, and in SCC with high risk for metastasis. Compared to immunocompetent SCC, genes associated with innate immunity, response to DNA damage and p53 regulation were differentially expressed in SCC from OTRs. In nude mice engrafted with human A431 cells, IL-22 and CSA treatment increased tumor growth and upregulated IL-22 receptor, JAK1 and STAT 1/3 expression. Ruxolitinib treatment significantly reduced tumor volume and reversed the accelerated tumor growth. CSA and IL-22 exacerbate aggressive behavior in SCC. Targeting the IL-22 axis via selective JAK/STAT inhibition may reduce the progression of aggressive SCC in OTRs, without compromising immunosuppression. In this study, microarray data was used to compare normal skin to immunocompetent SCC, to transplant associated SCC (TSCC)

Project description:Background and methods: Ruxolitinib (RUX), a Jak1/2 inhibitor, has been reported to attenuate murine bone marrow failure recently. Its potential toxocicty of anemia and thrombocytopenia in human remains a concern. To minimize its potential toxoxicity, we tested therapeutic effectsof low dose ruxolitinib plus cyclosporine in murine model of immune-mediated bone marrow failure. Bone marrow CD8 and CD4 T cells were sorted from treated or untreated bone marrow failure mice. RNA-Seq and analysis was performed using SMART-Seq mRNA LP Kit (Takara) and the Illumina Novaseq6000, according to the Institute's protocols. Results: low dose of ruxolitinib plus cyclosporine improved pancytopenia and BM cellularity and decreased BM T cell infiltration in bone marrow failure mice. RNA sequencing demonstrated that low dose of ruxolitinib plus cyclosporine suppressed immune-related pathways in bone marrow infiltrated CD8 T cells and MHC-II expression in CD4 T cells compared with untreated mice. Conclusion: Our results demonstrate that low dose of ruxolitinib plus cyclosporine remains the efficacy in attenuation of disease and extending survival of immune-mediated bone marrow failure mice.

Project description:Ruxolitinib is a Janus kinase 1/2 inhibitor (JAK1/2) that blocks signal transduction of interferon-gamma, a critical cytokine involved in the pathogenesis of cutaneous lichen planus (LP). In this prospective phase II study, we investigated the efficacy of topical ruxolitinib in cutaneous LP and performed transcriptomic analysis pre- and post-therapy. Twelve patients with cutaneous LP applied topical ruxolitinib twice daily for 8 weeks. Primary endpoints were change in total lesion count and modified Composite Assessment of Index Lesion Severity (mCAILS) score in index treated and untreated index control lesions at week 4. Total lesion count decreased by a median of 50 lesions (interquartile range 25, 723; p<0.001). mCAILS scores decreased by a mean difference of 7.6 (standard deviation 8.8, p=0.016) between index treated and control lesions. Type I and II interferon pathways were enriched in LP and responsive disease displayed downregulation of interferon-stimulated genes (ISGs). In this small pilot study, topical ruxolitinib was highly effective in the treatment of cutaneous LP. Transcriptomic analysis confirmed LP as an interferon-driven disease and downregulation of ISGs correlated with disease response.

Project description:To elucidate the gene profile of anti-fibroproliferative effects of cyclosporine, we added TGF-b and/or CsA to MRC5 (fetal human lung fibroblast) cell line. After 24 hours serum starvation, fibroblasts were treated with 3 ng/ml TGF-β1 and were treated with or without 2μg/ml Cyclosporine and effects were examined at 48 hours after treatment. Expression of three genes (IGFBP3, ID1 and PPARG) from this signature was quantified in the same RNA samples by real-time PCR. TGF-β and cyclosporine induced gene expression data was measured in MRC5 (fetal human fibroblast cell line) at 48h after treatments. The dose of TGF-β was 3 ng/ml and cyclosporine was 2 μg/ml. The comparison was done between four groups (control, TGF-β, cyclosporine and TGF-β plus cyclosporine).Three independent experiments were performed at each treatments using different samples for each experiment.

Project description:Calcineurin/NFAT signaling pathway has been shown to play important roles in various tissues such as the immune system, cardiac muscle and neuron. Although recent studies have shown that the pathway is involved in the regulation of hair growth, the precise mechanism is still unclear. In this study, we examine the molecular mechanism which is regulated by calcineurin/NFAT pathway, using two specific inhibitors for the pathway. Transcriptional profiling of human keratinocyte cell line, PHK cells, comparing control untreated PHK cells with cyclosporin A (CsA)-treated or 11R-VIVIT-treated PHK cells. Goal was to identify the effects of NFAT inhibitors on PHK cell proliferation. Cyclosporine A is a chemical compound, which strongly inhibits calcineurin phosphatase activity cooperating with cyclophilin, resulting in inhibition of NFAT signaling pathway. 11R-VIVIT is a cell-permeable peptide, which specifically interacts with NFAT and inhibits its binding to calcineurin, resulting in competitive inhibition of NFAT signaling pathway. Three-condition experiment; untreated PHK cells, CsA-treated PHK cells and 11R-VIVIT-treated PHK cells. Supplementary files: Significantly up-regulated genes across 4 different comparisons.
