Project description:HOIL-1L is an essential member of the linear ubiquitin assembly complex (LUBAC), which targets Nemo for linear ubiquitination during NF-kB activation in response to a variety of simuli, including LPS and TNFa treatment. HOIL-1L has also been suggested to function as a transcription factor. Here we analyzed changes in the global transcriptional profiles of primary bone marrow derived macrophage (BMDMs) from WT and HOIL-1L-/- mice upon treatment with NF-kB activating simuli. BMDMs were differentiated for 1 week and then treated with mock (untreated), 10ng/ml LPS, or 1ng/ml TNFa for 4 hours. RNA was immediately collected and analyzed in biological duplicates by the Agilent 8x60 mouse array.

Project description:Purpose: Our previous experiments showed that LPA activated inhibitory G-protein signaling in human GPR35-transfected cells. We wanted to test the LPA signaling in presence or absence of GPR35. Methods: We isolated RNA from bone-marrow derived macrophages (BMDMs) from WT or GPR35-deficient mice that were treated with LPA or LPS, and left untreated for control. Results: We have found that GPR35-deficiency alters the transcriptional profiles in response to LPA in BMDMs. On the other hand, LPS-treated WT and GPR35-deficient BMDMs showed similar transcriptional changes. Conclusion: GPR35-deficientcy alters the LPA but not LPS signaling.

Project description:The linear ubiquitin chain assembly complex (LUBAC) is the only known ubiquitin ligase that generates linear/Met1-linked ubiquitin chains. One of the LUBAC components, HOIL-1L, was recently shown to catalyse oxyester bond formation between the C-terminus of ubiquitin and some substrates. However, oxyester bond formation in the context of LUBAC has not been directly observed. We present the first 3D reconstruction of LUBAC obtained by electron microscopy and report its generation of heterotypic ubiquitin chains containing linear linkages with oxyester-linked branches. We found that addition of the oxyester-bound branches depends on HOIL-1L catalytic activity. We suggest a coordinated ubiquitin relay mechanism between the HOIP and HOIL-1L ligases supported by cross-linking mass spectrometry data, which show proximity between the catalytic RBR domains. Mutations in the linear ubiquitin chain-binding NZF domain of HOIL-1L reduces chain branching confirming its role in the process. In cells, these heterotypic chains were induced by TNF. In conclusion, we demonstrate that LUBAC assembles heterotypic ubiquitin chains with linear and oxyester-linked branches by the concerted action of HOIP and HOIL-1L.

Project description:Purpose: Mouse BMDM is the universal cell type of studying innate immunity. This study was designed to analyze LPS induced innate immune response and the gene expression in FABP5 KO BMDMs with overexpression of FABP5 WT or FABP5 C127S. Methods: FABP5 KO BMDMs were nucleofected with 5 μg pXJ40-3xFlag-FABP5 WT or C127S plasmid using the Amaxa Mouse Macrophage Nucleofector Kit (Lonza, VPA-1009) following the manufacturer’s instructions. Replace medium 6 hours post Nucleofection and add 500 ng/mL LPS to the fresh medium. 24 hours after treatment, harvest cells by using GenElute Single Cell RNA Purification Kit (Sigma, RNB300) and perform RNA-seq. Then mRNA profiles of these samples were generated by high-throughput sequencing analysis, using Illumina NovaSeq6000. And the differential mRNA profiles were analyzed. Results: mRNA profiles were analyzed, and differential expression profiles were compared. Conclusions: Our study demonstrated the transcriptional profiles of FABP5 KO BMDMs with overexpression of FABP5 WT or FABP5 C127S upon LPS treatment, with biologic replicates, generated by RNA-seq technology.

Project description:Exposure to hypoxia requires adaptive mechanisms for survival. During acute hypoxia, Na,K-ATPase endocytosis in alveolar epithelial cells (AEC) occurs via protein kinase C zeta (PKCζ) phosphorylation of α1- Na,K-ATPase independently of the hypoxia inducible factor (HIF). However, exaggerated Na,K-ATPase down-regulation leads to cell death. Here we report that during prolonged hypoxia plasma membrane Na,K-ATPase levels were maintained at ~50% of normoxic values due to HIF mediated regulation of HOIL-1L which targets PKCζ for degradation. Silencing HOIL-1L in the lung epithelium prevented PKCζ degradation causing Na,K-ATPase downregulation. Accordingly, HIF regulation of HOIL-1L targets the phosphorylated PKCζ for degradation and serves as an hypoxia-adaptive mechanism to stabilize the Na,K-ATPase avoiding significant lung injury.

Project description:Gene expression in bone marrow-derived macrophages (BMDMs) from WT and mice lacking the transcriptional repressor Kruppel-like factor 3 (KLF3). We cultured BMDMs from bone marrow for 7-10 days then treated cells with 100 ng/mL lipopolysaccharide (LPS) or vehicle (PBS) for 0 h or 8 h, followed by RNA extraction. We aimed to investigate deregulated genes and pathways in macrophages lacking KLF3, during the inflammatory response to endotoxin (LPS).
