Figure Lengend Snippet: PKC-like, PE/DAG-binding proteins are potential targets of immune activation retardation in neutrophils upon lead exposure. ( A ) Schematic diagram showing GSH/MRP-mediated sequestration-aided passive transport (SAPT) model and affinity gradient driven ion transfer. ( B ) Protein structure of the PKC-like, PE/DAG-binding domain from RAF1 (6XBH) and PKCD (2YUU). ( C ) Volcano plot of lead-treatment DEPs of INTERPRO term: PKC-like, PE/DAG-binding domain. ( D ) GSEA results of INTERPRO term: PKC-like, PE/DAG-binding domain showing a significantly increased thermostability upon lead in CETSA experiment. ( E ) DEPs degree centrality in KEGG pathways based on String database ( upper, heatmap ). Protein degree and eigenvector centrality across all KEGG pathways ( right ). ( F ) A subgraph of KEGG pathway (Map04660) of DAG activation in immune cells showing the critical position of RAF1, PKC and their downstream MAPK and phosphatidylinositol signaling. ( G ) GSEA analysis showing significantly reduced MAPK signaling in lead treated dHL-60 cells. ( H ) GSEA analysis showing significantly reduced phosphatidylinositol signaling in lead treated dHL-60 cells, and MK571 further enhanced lead-induced suppression on phosphatidylinositol signaling
