Figure Lengend Snippet: Mining of key genes for ferroptosis and verification in external databases. (A) The 5-set Venn diagram showing the comprehensive strategy among suppressor ferroptosis-associated genes (green circle), unclassified ferroptosis-associated genes (orange circle), marker ferroptosis-associated genes (blue circle), driver ferroptosis-associated genes (pink circle), and differentially expressed genes (DEGs) (purple circle). (B) ROC analysis for DUSP1 in the discovery dataset. (C) ROC analysis for PTGS2 in the discovery dataset. (D) ROC analysis for DUSP1 in the validation dataset. (E) ROC analysis for PTGS2 in the validation dataset. ROC, receiver operating characteristic.

Article Snippet: We chose CIL56 (T4309, TargetMol, America) to construct the ferroptosis model under the condition of 0.7 μM for 24 h. (E)-2-benzylidene-3-(cyclohexylamino)-2,3-dihydro-1H-inden-1-one (BCI) is a commonly used inhibitor of MKP-1.

Article Title: Ketogenesis acts as an endogenous protective programme to restrain inflammatory macrophage activation during acute pancreatitis

doi: 10.1016/j.ebiom.2022.103959

Figure Lengend Snippet: βOHB limits proinflammatory macrophage activation via class I HDACs, (a, b) Gene set enrichment analysis (GSEA) of gene expression in murine BMDMs are depicted. (a) Enrichment of TSA-upregulated signature genes (GSE22049) in βOHB-treated BMDMs. (b) Enrichment of HDAC3 depletion related signature genes (GES33162) in βOHB-treated BMDMs. (c, d) BMDMs treated with LPS (100 ng/ml) together with βOHB (10 mM), TSA (1 μΜ), or MS-275 (20 μM) for 4 h. (c) Flow cytometry analysis of intracellular TNFα levels. (d) Quantitative PCR analysis of Nos2, Il6, Il12b , and Tnfa mRNA expression. (e) ChIP-qPCR analysis of H3Ac and H4Ac occupancy in Edn1, Il12a , and Nos2 loci in the indicated group, with IgG as the control. (f) Ingenuity Pathway Analysis (IPA) of genes in cluster A. (g) BMDMs were pretreated with βOHB (10 mM) or TSA (1 μΜ) 1 h prior to LPS (100 ng/ml) stimulation for 15 min. Acylated p65 levels were determined by immunoprecipitation, while p-p65 and total p65 were determined by immunoblotting. (h) Mice were i.p. injected with TSA (0.1 mg/kg), MS-275 (20 mg/kg) or DMSO as a control 1 h prior to the CER-AP (Cer*7) induction and were harvested at 24 h thereafter (n = 5 / group). Frequency of TNFα + macrophagess (F4/80 + CD11b + ) in pancreatic leukocytes from the indicated groups. Data are presented as the mean ± SD in bar graphs (c–e) or the mean ± SEM in dot plots (h). *p < 0.05, **p < 0.01, ***p < 0.001

Article Snippet: For treatments, the Balb/c mice were (1) fed with 1,3-butanediol (5.72% (w/v); Sigma-Aldrich) or normal water (control) one week before disease induction; received a single intraperitoneal injection of βOHB (3 mmol/kg; Sigma-Aldrich) or normal saline at the indicated time; and (3) the CPT1α inhibitor etomoxir (20 mg/kg, Sigma-Aldrich), histone deacetylase (HDAC) pan inhibitor TSA (0.1 mg/kg; Targetmol), HDAC1/3 inhibitor MS-275 (20 mg/kg; Targetmol), or dimethyl sulfoxide (DMSO) as a control 1 h before disease induction.
