Project description:We studied the role of the histone methyltransferase DOT1L in T cell development and differentiation. Here we generated RNA-seq data from sorted CD8 subpopulations from WT (Lcre+/-) and Dot1L KO (Lcre+/-;Dot1Lfl/fl) mice. This data was to define tissue specific expression signatures and it was compared with H3K79me2 ChIP-seq data from the same subsets.

Project description:We studied the role of the histone methyltransferase DOT1L in T cell development and differentiation. We generated RNA-seq data from sorted CD8 effector T cells from WT (Lck-cre+/-) and Dot1L KO (Lck-cre+/-;Dot1Lfl/fl) mice infected with Listeria monocytogenes. This data was compared with H3K79me2 ChIP-seq data from the same T cell subset.

Project description:We studied the role of the histone methyltransferase DOT1L in T cell development and differentiation. H3K79me2 and H3K4me3 ChIP-sequencing data was generated from sorted CD8 single positive thymocytes, naïve CD8 splenocytes and memory CD8 splenocytes. This was compared to RNA-sequencing data from WT and Dot1L KO mice in order to study the link between H3K79me2 and transcription.

Project description:B7S1 negatively regulates T cells and its expression correlates with poor prognosis of cancer patients. In order to understand how B7S1 signaling contributes to dysfunction of CD8+ T cell in the TME, we conducted transcriptional analysis of OVA-specific CD8+ TILs and different TIL subsets from E.G7-bearing WT and B7S1 KO mice (Day 21).

Project description:Purpose: To characterize transcriptional changes associated with homozygous inactivation of Dot1l or Mll1 in MN1 driven AML Methods: We sequenced mRNA from murine LSK-cells transformed using forced expression of MN1 (MSCV-MN1-IRES-GFP), and transduced with Cre-vector to inactivate either Dot1l or Mll1. Cells were sorted for Cre-expression (pTomato fluorescent marker) or expression of an inert control vector. Results: Inactivation of either Dot1l or Mll1 in this model leads to a substantial delay or complete abrogation of leukemia development. Loss of Dot1l or Mll1 are associated with gene expression changes that have substantial overlap. In addition, genes that are downregulated follwing inactivation of Dot1l or Mll1 have substantial overlap with the gene set upregulated in MN1 transduced CMPs. Conclusions: MN1 mediated leukemogenesis is associated with a gene expression program that dependes on Mll1 and Dot1l Examination of mRNA levels between Dot1l f/f and Dot1l ko, and Mll1 f/f and Mll1 ko.

Project description:The goal of this study was to examine differences in gene expression of tumor specific CD8 T cells in an in vivo tumor mouse model after inhibition of galectin-3 protein expression by genetic knockout. Galectin-3 is thought to modulate CD8 T cell response by cross-linking cell surface glycoproteins Galectin-3 is a 31 kD carbohydrate-binding lectin that is over-expressed by many human malignancies. It also modulates T cell responses through a diverse array of mechanisms including induction of apoptosis, TCR cross linking in CD8+ T cells, and T cell receptor (TCR) down regulation in CD4+ T cells. We found that patients responding to a granulocyte-macrophage colony-stimulating factor (GM-CSF) secreting allogeneic pancreatic tumor vaccine developed post immunization antibody responses to galectin-3 on a proteomic screen. We used the HER-2/neu (neu-N) transgenic mouse model to study galectin-3 binding on adoptively transferred high avidity neu-specific CD8+ T cells derived from TCR transgenic mice. Here, we show that galectin-3 binds preferentially to activated antigen-committed CD8+ T cells only in the tumor microenvironment (TME). Galectin-3 deficient mice exhibit improved CD8+ T cell effector function and increased expression of several inflammatory genes when compared with wild type (WT) mice. We also show that galectin-3 binds to LAG-3, and LAG-3 expression is necessary for galectin-3 mediated suppression of CD8+ T cells in vitro. Lastly, galectin-3 deficient mice have significantly elevated levels of circulating plasmacytoid dendritic cells (pDCs), which are superior to conventional dendritic cells (cDCs) in activating CD8+ T cells. Binding of galectin-3 to cell-surface glycoproteins on immune cells suppresses a pro-inflammatory immune response. Thus, inhibiting galectin-3 in conjunction with CD8+ T cell directed immunotherapies should enhance the tumor specific immune response. 3 different experimental groups were studied. Galectin-3 WT CD8 T cells adoptively transferred into Galectin-3 WT mice, galectin-3 WT CD8 T cells transferred into galectin-3 KO mice, and finally galectin-3 KO CD8 T cells transferred into galectin-3 KO mice. Galectin-3 WT CD8 T cells transferred into Galectin-3 WT mice were used as the reference group. Four biological replicates were submitted for each group, and adoptively transfered CD8 T cells were isolated 5 days post-adoptive transfer into tumor-bearing mice treated with a whole cell GM-CSF secreting vaccine. Cells were purified by cell sorting on the Thy1.2 surface marker.
