Project description:transcriptional profiling was performed on Regnase-1 KO CAR and Regnase-1 TCF-1 DKO CAR T cells isolated 7days after co-transfer into tumor bearing mice. TCF-1 deficiency in Regnase-1 KO CAR T cells led to reduced long-term persistence and memory-like phenotype.

Project description:Regulation of lineage biases in hematopoietic stem and progenitor cells (HSPCs) is pivotal for balanced hematopoietic output. However, little is known about the mechanism behind lineage choice in HSPCs. Here, we show that mRNA decay factors Regnase-1 (Zc3h12a) and Regnase-3 (Zc3h12c) are critical for induction of myeloid lineage priming, restricting lymphoid differentiation in HSPCs. Regnase-1- and Regnase-3-mediated control of mRNA encoding Nfkbiz, a transcriptional and epigenetic regulator, was essential for balancing lymphoid/myeloid lineage output in HSPCs in vivo. Furthermore, single cell-assay for transposase-accessible chromatin sequencing (scATAC-seq) analysis revealed that Regnase-1 and Regnase-3 control the epigenetic landscape on myeloid-related gene loci in hematopoietic stem cells (HSCs) via Nfkbiz. Consistently, an antisense oligonucleotide designed to inhibit Regnase-1- and Regnase-3-mediated Nfkbiz mRNA degradation primed HSCs toward myeloid lineages by enhancing Nfkbiz expression. Collectively, the collaboration between post-transcriptional control and chromatin remodeling by the Regnase-1/Regnase-3-Nfkbiz axis governs lineage priming, instructing HSC lineage specification.

Project description:Post-transcriptional regulation of immune-related transcripts by RNA-binding proteins (RBPs) impacts immune cell responses, including mast cell functionality. Despite their importance in immune regulation, the functional role of most RBPs remains to be understood. By manipulating the expression of specific RBPs in murine mast cells, coupled with mass spectrometry and transcriptomic analyses, we found that the Regnase family of proteins acts as a potent regulator of mast cell physiology. Specifically, Regnase-1 is required to maintain basic cell proliferation and survival, while both Regnase-1 and -3 cooperatively regulate the expression of inflammatory transcripts upon activation, with Tnf being a primary target in both human and mouse cells. Further, Regnase-3 directly interacts with Regnase-1 in mast cells and is necessary to restrain Regnase-1 expression through the destabilization of its transcript. Overall, our study identifies protein interactors of endogenously expressed Regnase factors, characterizes the regulatory interplay between Regnase family members in mast cells, and establishes their role in the control of mast cell homeostasis and inflammatory responses.

Project description:The RNase Regnase-1 is a master RNA regulator in macrophages and T cells that degrades cellular and viral RNA upon NF-kB signaling. The roles of the other Regnase family-members remain largely unknown. Here, we analyze Regnase-3 deficient mice, which develop hypertrophic lymph nodes. We used various mice with immune cell specific deletions of Regnase-3 to demonstrate that Regnase-3 acts specifically within myeloid cells. Regnase-3 deficiency systemically increased interferon signaling, which increased the proportion of immature B and innate immune cells and suppressed follicles and germinal center formation. Expression analysis revealed that Regnase-3 and Regnase-1 share protein degradation pathways. Nevertheless, Regnase-3 expression is specifically high in macrophages and transcriptionally controlled by interferon signaling. Although direct targets in macrophages remain unknown, Regnase-3 can bind, degrade and regulate mRNAs, such Zc3h12a encoding Regnase-1, in vitro. These data indicate that Regnase-3, like Regnase-1, is an RNase and essential for immune homeostasis, but has diverged as a key regulator for the interferon pathway in macrophages.

Project description:Dysregulation of mast cell activation can lead to allergic and anaphylactic reactions. Post-transcriptional regulation of immune-related transcripts by RNA-binding proteins (RBPs) is critical in controlling immune cell responses, including mast cell functionality. The Regnase family of RBPs plays a central role in regulating gene expression and controlling immune responses in both lymphoid and myeloid cells. However, what is the functional role of Regnase proteins in mast cells remains to be understood. Using different approaches of Regnase proteins depletion and deletion as well as overexpression by mRNA delivery, we found that Regnase-1 is a powerful negative regulator of mast cell proliferation, survival and ability to produce inflammatory cytokines. On the other hand, Regnase-3 was essential to modulate Regnase-1 expression in mast cells by direct targeting of the 3’-untranslated region of Regnase-1, leading to the destabilization of the Zc3h12a mRNA. Regnase-1 deletion had widespread effect on mast proliferation and survival even in the absence of stimulation and was at least in part linked to specific nuclear functions of Regnase-1 in modulating the ability of mast cells to withstand DNA damage. Overall, we describe the importance of Regnase proteins in modulating mast cell homeostatic and inflammatory responses and we describe the impact of Regnase-1 in the maintenance of genome stability.

Project description:The Wnt signaling pathway is involved in many differentiation events during embryonic development and can lead to tumor formation after aberrant activation of its components. ?-catenin, a cytoplasmic component, plays a major role in the transduction of the canonical wnt/ ?-catenin signaling. The aim of this study was to identify novel genes that are regulated by active ?-catenin/TCF signaling in hepatocellular carcinoma. We selected and expanded isogenic clones from hepatocellular carcinoma-derived Huh7 cells with high and low ?-catenin/TCF activities. We showed that, high TCF activity Huh7 cells lead to bigger and more aggressive tumors when xenografted into nude mice. We used SAGE (Serial Analysis of Gene Expression), genome-wide microarray and in silico promoter analysis in parallel, to compare gene expression between low (basal) and high (transfected) ?-catenin/TCF activity clones, those had been xenografted into nude mice. We compared and contrasted SAGE and genome-wide microarray data, in parallel. Finally; after combined analysis, we identified BRI3 and HSF2 as novel targets of Wnt/?-catenin signaling in hepatocellular carcinoma. High TCF activity Huh7 cell line (Huh7-S33Y) was compared to control Huh7 cell line (Huh7-Vec) by using 25 ug of total RNA isolated from each sample
