Article Title: Cultured bacteria isolated from primary sclerosing cholangitis patient bile induce inflammation and cell death
doi: 10.1128/msphere.00550-25
Figure Lengend Snippet: PSC bacterial supernatants affected transcription of genes related to sulfur metabolism, mucin expression, and the bicarbonate umbrella in biliary and hepatic cells. Biliary (EGI-1) and hepatic (HepG2) cells were treated with a 1:1 ratio (vol/vol) of bacterial culture supernatant to cell culture medium for 6 h under anaerobic conditions, and the effect on transcription of target genes was assessed by qPCR. BHI+ medium was used as a control. E. gallinarum was used as a reference strain and was not derived from PSC patients, as indicated by striped bars. Results were normalized to UBC mRNA expression. The following isolates were used in these experiments : E. faecalis _PSC06_col01, E. coli _PSC10_col01, F. necrophorum _PSC08_col02, K. pneumoniae _PSC09_col49 (H 2 S producer), K. pneumoniae _PSC03_col01 (non-producer), S. salivarius _PSC01_col01, V. dispar _PSC07_col14, and V. parvula _PSC07_col05. One-way ANOVA was performed followed by Dunnett’s multiple comparisons test using Graphpad Prism 10 software (values are shown as mean ± SD; four biological replicates from independent experiments with three technical replicates each; * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001).
