Small sized mesenchymal stem-cells primed with hypoxia attenuate graft-versus-host disease [transcriptome dataset]

Project description:Mesenchymal stem-cells (MSCs) are of particular interest for treating immune-related diseases due to their immunosuppressive capacities. Here, we show that Small sized MSCs primed with Hypoxia and Calcium ion (SHC-MSCs) exhibit the enhanced functions regarding stemness and immunomodulation for treating allogeneic conflicts. Compared with naïve cultured human umbilical cord-blood MSCs, SHC-MSCs were resistant to the passage dependent cellular senescence mediated by MCP-1 and p53/p21 cascade and highly secreted the pro-angiogenic and immune-modulatory factors, resulting in suppression of T-cell proliferation. Genome-wide DNA methylome and transcriptome analysis indicate that SHC-MSCs characteristically up-regulated immune-modulation, cell adhesion and cell-cycle related genes. As downstream factors, PLK1, ZNF143, DHRS3, and FOG2 proteins played a key role on the beneficial effects of SHC-MSCs, evidenced by the promoted self-renewal, migration, pro-angiogenic, anti-inflammatory, and T cell suppression capacities in their-over-expressing MSCs. Importantly, administration of SHC-MSCs or PLK1-over-expressing cells (PLK1-MSCs) significantly reduced the symptoms of graft-versus-host disease (GVHD) in a humanized mouse model which led to significantly improved survival, less weight loss, and less histopathologic injuries of GVHD target organs compared with naive MSC-infused mice. Collectively, our study suggests that small-sized MSCs primed with hypoxia could advance the therapeutic strategy for the clinical treatment of allogeneic conflicts including GVHD.

Small hypoxia-primed mesenchymal stem cells attenuate graft-versus-host disease.

Project description:Mesenchymal stem cells (MSCs) are of particular interest for the treatment of immune-related diseases due to their immunosuppressive capacity. Here, we show that Small MSCs primed with Hypoxia and Calcium ions (SHC-MSCs) exhibit enhanced stemness and immunomodulatory functions for treating allogeneic conflicts. Compared with naïve cultured human umbilical cord blood-derived MSCs, SHC-MSCs were resistant to passage-dependent senescence mediated via the monocyte chemoattractant protein-1 and p53/p21 cascade and secreted large amounts of pro-angiogenic and immunomodulatory factors, resulting in suppression of T-cell proliferation. SHC-MSCs showed DNA demethylation in pluripotency, germline, and imprinted genes similarly to very small embryonic-like stem cells, suggesting a potential mutual relationship. Genome-wide DNA methylome and transcriptome analyses indicated that genes related to immune modulation, cell adhesion, and the cell cycle were up-regulated in SHC-MSCs. Particularly, polo-like kinase-1 (PLK1), zinc-finger protein-143, dehydrogenase/reductase-3, and friend-of-GATA2 play a key role in the beneficial effects of SHC-MSCs. Administration of SHC-MSCs or PLK1-overexpressing MSCs significantly ameliorated symptoms of graft-versus-host disease (GVHD) in a humanized mouse model, resulting in significantly improved survival, less weight loss, and reduced histopathologic injuries in GVHD target organs compared with naïve MSC-infused mice. Collectively, our findings suggest that SHC-MSCs can improve the clinical treatment of allogeneic conflicts, including GVHD.

Comparison of gene expresson between larger sized tetraploid and smaller sized diploid HCA2

Project description:In order to determine the factors that regulate senescence induction, we tried to identfy genes that are predominantly expressed in large sized senescent cells with tetraploid DNA. We sorted large or small sized HCA2 cells treated wth IR (10Gy) according to size and structure (FSC and SSC) by FACScan and analyzed global gene expression patterns.

Kras-Deficient T Cells Attenuate Graft-versus-Host Disease but Retain Graft-versus-Leukemia Activity.

Project description:Acute graft-versus-host disease (aGVHD) is one major serious complication that is induced by alloreactive donor T cells recognizing host Ags and limits the success of allogeneic hematopoietic stem cell transplantation. In the current studies, we identified a critical role of Kras in regulating alloreactive T cell function during aGVHD. Kras deletion in donor T cells dramatically reduced aGVHD mortality and severity in an MHC-mismatched allogeneic hematopoietic stem cell transplantation mouse model but largely maintained the antitumor capacity. Kras-deficient CD4 and CD8 T cells exhibited impaired TCR-induced activation of the ERK pathway. Kras deficiency altered TCR-induced gene expression profiles, including the reduced expression of various inflammatory cytokines and chemokines. Moreover, Kras deficiency inhibited IL-6-mediated Th17 cell differentiation and impaired IL-6-induced ERK activation and gene expression in CD4 T cells. These findings support Kras as a novel and effective therapeutic target for aGVHD.
