Thrombin induces ACSL4-dependent ferroptosis during cerebral ischemia/reperfusion. Signal Transduct Target Ther 2022; 7:59. [PMID: 35197442 PMCID: PMC8866433 DOI: 10.1038/s41392-022-00917-z] [Citation(s) in RCA: 112] [Impact Index Per Article: 56.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 11/14/2021] [Accepted: 01/31/2022] [Indexed: 02/08/2023] Open
Abstract
Ischemic stroke represents a significant danger to human beings, especially the elderly. Interventions are only available to remove the clot, and the mechanism of neuronal death during ischemic stroke is still in debate. Ferroptosis is increasingly appreciated as a mechanism of cell death after ischemia in various organs. Here we report that the serine protease, thrombin, instigates ferroptotic signaling by promoting arachidonic acid mobilization and subsequent esterification by the ferroptotic gene, acyl-CoA synthetase long-chain family member 4 (ACSL4). An unbiased multi-omics approach identified thrombin and ACSL4 genes/proteins, and their pro-ferroptotic phosphatidylethanolamine lipid products, as prominently altered upon the middle cerebral artery occlusion in rodents. Genetically or pharmacologically inhibiting multiple points in this pathway attenuated outcomes of models of ischemia in vitro and in vivo. Therefore, the thrombin-ACSL4 axis may be a key therapeutic target to ameliorate ferroptotic neuronal injury during ischemic stroke.

Niu Z, Fu M, Li Y, Ren H, Zhang X, Yao L. Osthole alleviates pulmonary vascular remodeling by modulating microRNA-22-3p mediated lipid metabolic reprogramming. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2022; 96:153840. [PMID: 34836745 DOI: 10.1016/j.phymed.2021.153840] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 09/02/2021] [Accepted: 10/27/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Pulmonary vascular remodeling is the key pathological feature of pulmonary arterial hypertension (PAH) characterized by a pattern of lipid-related insulin resistance(IR), hormonal derangements and metabolic reprogramming. Our previous studies have demonstrated osthole as natural coumarin compound derived from traditional Chinese medicine is a promising agent for the treatment of pulmonary vascular remodeling in PAH. PURPOSE The present study sought to delineate lipid metabolic modulatory mechanism of osthole against pulmonary vascular remodeling by employing an interdisciplinary strategy. METHODS Rat model with PAH induced with MCT and PASMCs proliferation model induced with PDGF-BB were established in this study. Serum and lung tissues were used to lipid-related IR, hormone related indexes, pulmonary vascular remodeling analysis. Then, lipid metabolic gene, key enzymes, metabolites and cell proliferation indexes were examined to investigate metabolic regulatory mechanism in vivo and vitro model of PAH. RESULTS Osthole significantly showed improvement of lipid-related IR and hormone dysregulation in rats with PAH evidenced by elevating testosterone, androgen receptor and cyclic guanosine monophosphate (cGMP), inhibiting phosphodiesterase-5(PDE-5), modulating lipid-related IR indexes total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), triglyceride (TG)/HDL-C ratio. Additionally, osthole limited key metabolic gene and enzymes to inhibit accumulation of decadienyl-l-carnitine in lipid metabolism, thus to promote oxidative phosphorylation and ATP production through inhibition of miRNA-22-3p, fatty acid translocase (CD36), fatty acid synthase (FAS), phospholipase A2 (PLA2), carnitine palmitoyltransferase 1A (CPT1A), hexokinase 2 (HK2), activation of metabolic switch isocitrate dehydrogenase 3α (IDH3α), NADH dehydrogenase 1 (ND1). We found for the first time miRNA-22-3p modulated PASMCs proliferation and vascular remodeling by regulating lipid metabolism reprogramming. Those modifications uncovered therapeutic mechanism of osthole against pulmonary vascular remodeling. CONCLUSION Our findings revealed the function of miRNA-22-3p in PASMCs and demonstrated a novel mechanism that miRNA-22-3p as a regulator can be targeted by osthole to greatly restore dysregulated lipid metabolism thus to alleviate pulmonary vascular remodeling in PAH, which provides novel insight into the potential therapeutic target for PAH, further highlights the development potential of osthole derived new drug against PAH.

Genome-Wide Association Study Based on Random Regression Model Reveals Candidate Genes Associated with Longitudinal Data in Chinese Simmental Beef Cattle. Animals (Basel) 2021; 11:ani11092524. [PMID: 34573489 PMCID: PMC8470172 DOI: 10.3390/ani11092524] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 08/24/2021] [Accepted: 08/25/2021] [Indexed: 12/24/2022] Open
Abstract
Simple Summary Genome-wide association study (GWAS) has become the main approach for detecting functional genes that affects complex traits. For growth traits, the conventional GWAS method can only deal with the single-record traits observed at specific time points, rather than the longitudinal traits measured at multiple time points. Previous studies have reported the random regression model (RRM) for longitudinal data could overcome the limitation of the traditional GWAS model. Here, we present an association analysis based on RRM (GWAS-RRM) for 808 Chinese Simmental beef cattle at four stages of age. Ultimately, 37 significant single-nucleotide polymorphisms (SNPs) and several important candidate genes were screened to be associated with the body weight. Enrichment analysis showed these genes were significantly enriched in the signaling transduction pathway and lipid metabolism. This study not only offers a further understanding of the genetic basis for growth traits in beef cattle, but also provides a robust analytics tool for longitudinal traits in various species. Abstract Body weight (BW) is an important longitudinal trait that directly described the growth gain of bovine in production. However, previous genome-wide association study (GWAS) mainly focused on the single-record traits, with less attention paid to longitudinal traits. Compared with traditional GWAS models, the association studies based on the random regression model (GWAS-RRM) have better performance in the control of the false positive rate through considering time-stage effects. In this study, the BW trait data were collected from 808 Chinese Simmental beef cattle aged 0, 6, 12, and 18 months, then we performed a GWAS-RRM to fit the time-varied SNP effect. The results showed a total of 37 significant SNPs were associated with BW. Gene functional annotation and enrichment analysis indicated FGF4, ANGPT4, PLA2G4A, and ITGA5 were promising candidate genes for BW. Moreover, these genes were significantly enriched in the signaling transduction pathway and lipid metabolism. These findings will provide prior molecular information for bovine gene-based selection, as well as facilitate the extensive application of GWAS-RRM in domestic animals.

Epidermal growth factor induces platelet-activating factor production through receptors transactivation and cytosolic phospholipase A2 in ovarian cancer cells. J Ovarian Res 2014; 7:39. [PMID: 24721622 PMCID: PMC4005630 DOI: 10.1186/1757-2215-7-39] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2014] [Accepted: 04/08/2014] [Indexed: 11/17/2022] Open
Abstract
Background Among the pro-inflammatory lipid mediators, platelet-activating factor (PAF) is a major primary and secondary messenger that binds to the PAF-receptor (PAFR). Epidermal growth factor (EGF) is a polypeptide growth factor that binds to the EGF-receptor (EGFR). Evidence suggests that both PAF and EGF play a significant role in oncogenic transformation, tumor growth, neoangiogenesis and metastasis, including ovarian cancer. PAF has the potential to transactivate EGFR in ovarian cancer cells. This study explores the mechanisms involved in EGF-induced PAF production. Methods The effect of EGF on PAF production in ovarian cancer cells was observed using enzyme-linked immunosorbent assay. The receptors transactivation and the role of cytosolic phospholipase A2 (cPLA2) in modulating PAF production induced by EGF was assessed using pharmacological inhibitors, si-RNA knockdown, targeted gene overexpression and immunocytochemistry. The signaling pathways invovled in PAF production induced by EGF in ovarian cancer cells were assessed. Results We demonstrate that EGF increases the production of PAF in CAOV3 and SKOV3 ovarian cancer cell lines. EGF induces the transactivation of PAFR, which can be blocked by an EGFR inhibitor. Inhibition of EGFR and/or PAFR blocks PAF production in response to EGF. EGF-induced PAF production involves the phosphorylation of extracellular-regulated protein kinase (ERK) and cytosolic phospholipase A2 (cPLA2). A cPLA2 inhibitor blocks EGF-induced PAF production as well as si-cPLA2, while overexpression of cPLA2 increases PAF production. Conclusions These results indicate that EGF stimulates PAF production in ovarian cancer cells in a manner that requires cPLA2. We have also determined that crosstalk can occur bidirectionally between EGFR and PAFR, suggesting that EGF-induced PAF production could result in positive feedback that acts on the PAF-receptor to promote ovarian cancer progression.
