Figure Lengend Snippet: Generation of PAD2KO mice using the CRISPR-Cas9 systems and pathogenesis of TNBS-induced colitis in wild-type and PAD2KO mice. ( a ) The sequences produced for the generation of PAD2KO mice using the CRISPR-Cas9 systems, deficient in 61-bp on exon2 of the genomic PAD2 DNA. ( b ) PAD2 mRNA level was determined in intraperitoneal macrophages by qRT-PCR normalized to TBP. Data were presented as the means ± S.E.M. (n = 8). ****P < 0.0001 vs. wild-type (WT) mice. ( c ) PAD2 expression was determined in intraperitoneal macrophages by western blotting normalized to β-actin expression. Data are presented as the means ± S.E.M. (n = 3). ***P < 0.001 vs. WT mice. ( d ) Body weight was measured daily in untreated-, vehicle (30% ethanol)-, or TNBS-injected WT and PAD2KO mice. On day 3, colon length was measured ( e ), representative images were obtained ( f ), and macroscopic analyses of the injured area were carried out using Image J ( g ). Scale bars are 10 mm. Histological changes were observed following H&E staining ( h ). ( i ) MPO activity was determined in those mice. Data are presented as the means ± S.E.M. (n = 8–9). #### P < 0.0001 vs. vehicle-injected mice (WT EtOH), and ****P < 0.0001, ***P < 0.001, *P < 0.05 vs. TNBS-injected mice (WT TNBS).

Article Snippet: The membranes were then incubated with PAD2 antibody (1:500) (Proteintech, 12110-1-AP) and β-actin antibody (1:2000) (CST, #4970).

Figure Lengend Snippet: Expression of inflammatory cytokines, chemokines, and PAD2 in PAD2KO mice. ( a ) TNFα, ( b ) IL-1β, ( c ) IL-12, ( d ) IL-23, ( e ) IFNγ, ( f ) CXCL2, and ( g ) PAD2 mRNA expression were determined using qRT-PCR in colon tissues of vehicle (30% ethanol)-, or TNBS-injected WT and PAD2KO mice on day 3, and mRNA levels were normalized to TBP. Data are presented as the means ± S.E.M. (n = 8–10). #### P < 0.0001, ### P < 0.001, ## P < 0.01 vs. vehicle-injected mice (WT EtOH), and ****P < 0.0001, *P < 0.05 vs. TNBS-injected mice (WT TNBS).
