Project description:GATA3 is indispensable for the development of all IL-7Rα-expressing innate lymphoid cells (ILCs) and maintenance of type 1 ILCs (ILC1s) and type 2 ILCs (ILC2s). However, the importance of low GATA3 expression in type 3 ILCs (ILC3s) is still elusive. Here, we report that GATA3 regulates homeostasis of ILC3s by controlling IL-7Rα expression. In addition, GATA3 is critical for the development of NKp46+ ILC3 subset partially through regulating the balance between T-bet and RORγt. Genome-wide analyses indicate that while GATA3 positively regulates CCR6+ and NKp46+ ILC3 subset-specific genes in respective lineages, it negatively regulates CCR6+ ILC3-specific genes in NKp46+ ILC3s. Furthermore, GATA3 regulates IL-22 production in both CCR6+ and NKp46+ ILC3s. Thus, low GATA3 expression is critical for the development and function of ILC3 subsets. To identify GATA3 regulated genes in total ILC3s with RNA-Seq; To identify unique genes expressed by CCR6+ ILC3 or NKp46+ ILC3 and GATA3 regulated genes within these two ILC3 subsets with RNA-Seq; To identify GATA3 direct binding sites in ILC3s, ILC2s and Th2 cells with ChIP-Seq.

Project description:Splenic and intestinal NCR- ILC3s have been shown to be phenotypically and functional different. The goal of this study is to compare transcriptional profiles of NCR- ILC3s isolated of the murine spleen (SP) and the small intestine (SI) by RNA seq technology. Cell suspension were generated from both organs and NCR- ILC3s (CD117+, Thy1.2+, eYFP+, lin- (CD3, CD8, CD11b, CD11c, CD19, B220, Gr-1, TCRβ, TCRγδ, TER-119, NK1.1, NKp46)) were sort purified. RNA was isolated and RNA sequencing was done using Ilumina Hiseq 2500 system and NuGEN Ovation RNA Seq System V2, with biological triplicates. We provide the first comparison of transcriptional profiles of intestinal and splenic NCR- ILC3s.

Project description:Ferroptosis is an iron-dependent programmed cell death associated with severe kidney diseases, linked to decreased glutathione peroxidase 4 (GPX4). However, the spatial distribution of renal GPX4-mediated ferroptosis and the molecular events causing GPX4 reduction during ischemia-reperfusion (I/R) remain largely unknown. Using spatial transcriptomics, we identify that GPX4 is situated at the interface of the inner cortex and outer medulla, a hyperactive ferroptosis site post-I/R injury. We show that OTU deubiquitinase 5 (OTUD5) is a GPX4-binding protein that confers ferroptosis resistance by stabilizing GPX4. During I/R, ferroptosis is induced by mTORC1-mediated autophagy, causing OTUD5 degradation and subsequent GPX4 decay. Functionally, OTUD5 deletion intensifies renal tubular cell ferroptosis and exacerbates acute kidney injury, while AAV-mediated OTUD5 delivery mitigates ferroptosis and promotes renal function recovery from I/R injury. In this work, our study highlights a new autophagy-dependent ferroptosis module: hypoxia/ischemia-induced OTUD5 autophagy triggers GPX4 degradation, offering a potential therapeutic avenue for I/R-related kidney diseases.

Project description:Background: Intestinal failure-associated liver disease (IFALD) is a common complication of long-term parenteral nutrition (PN) that is associated with significant morbidity and mortality. Ferroptosis, as an iron-dependent regulated cell death, has been shown to play an important role in the development of several liver diseases. This study focuses on investigating whether the ferroptosis phenomenon is present in TPN-induced IFALD and further exploring the potential regulatory mechanisms. Methods: Ferroptosis hallmarkers were measured in children with short bowel syndrome (SBS) who had long-term PN use and caused IFALD. Sprague-Dawley (SD) rats were used to establish a rat model of IFALD with a concomitant ferroptosis inhibition intervention using liproxstain-1. The mir-431 lineage was identified as a potential upstream regulatory mir-RNA by mir-RNA sequencing. HepG2 and 293T cell line was used to demonstrate that mir-431 regulates ferroptosis through the GPX4 pathway at the cellular level in vitro. Results: Ferroptosis is upregulated in liver of children with IFALD. Liproxstain-1 downregulates ferroptosis in a rat model of IFALD and attenuates hepatic steatosis through the lipid metabolism pathway. In vitro HepG2 and 293T cell experiments reveal that mir-431 affects ferroptosis by regulating GPX4 protein. Conclusions: Ferroptosis plays an important role in the development of IFALD. Liproxstain-1 inhibits ferroptosis and attenuates hepatic steatosis in a rat model of IFALD through the lipid metabolism pathway. Mir-431 negatively regulates GPX4 protein-induced ferroptosis.

Project description:Ferroptosis is an iron-dependent cell death mechanism characterized by an accumulation of toxic lipid peroxides and membrane rupture. The glutathione dependent enzyme, GPX4 (glutathione peroxidase 4), prevents ferroptosis by reducing these lipid peroxides into non-toxic lipid alcohols. Ferroptosis induction by GPX4 inhibition has emerged as a vulnerability of cancer cells, thus highlighting the need to identify ferroptosis regulators that may be exploited therapeutically. Through genome-wide screens and a series of genetic, genomic, and quantitative imaging approaches, we identify the SWI-SNF ATPases BRM and BRG1 as ferroptosis suppressors. Mechanistically, they directly bind to and catalytically increase chromatin accessibility at NRF2 target loci, thus boosting NRF2 transcriptional output. This primes cells to counter lipid peroxidation and confers resistance to GPX4 inhibition and ferroptosis. Importantly, we demonstrate that the BRM/BRG1-ferroptosis connection can be leveraged to enhance the paralog dependency of BRG1-mutant lung cancer cells on BRM, especially in lines that are less sensitive to BRM inhibition or degradation. Our data reveal ferroptosis induction as a potential avenue for broadening the efficacy of BRM degraders/inhibitors and define a specific genetic context for exploiting GPX4 dependency.
