Data represent the average of log2 (Hy5/Hy3) ratios from non-stimulated cell cultures (n = 3), LPS treated cultures (n = 3) by using the miRCURYTM LNA Array (Version 8.1).

Figure S1. Promoter binding of p65 transactivates the IL-8 gene in biliary epithelial cells in response to LPS stimulation. (A) p65-dependent upregulation of IL-8 mRNA in cholangiocytes after LPS treatment. Bars represent the levels of IL-8 mRNA in cells following LPS stimulation in the presence or absence of SC-514 as assessed by real-time PCR. (B) A schematic diagram shows the structure of IL-8 gene. ChIP analysis demonstrated increased binding of p65 to the binding site at IL-8 promoter in cells following stimulation. , p < 0.05 t test vs non-stimulated cells; #, p < 0.05 t test vs LPS-stimulated cells.

Figure S2. Promoter binding of p65 transactivates mir-130a gene in biliary epithelial cells in response to LPS stimulation. (A) The schematic diagram shows one potential binding sites in the putative promoter element of mir-130a gene. ChIP analysis revealed increased binding of

p65 to the promoter binding site in H69 cells following LPS treated. (B) H69 cells were transfected with luciferase reporter construct covering the potential binding sites of the mir-130a promoter and then exposed to LPS in the presence or absence of SC-514. (C) H69 cells were co-transfected with the pCMV-p65 to overexpress p65 and the luciferase reporter construct containing the mir-130a promoter. , p < 0.05 t test vs non-stimulated cells (in B) or empty pCMV vector control (in C); #, p < 0.05 t test vs LPS-stimulated cells (in B).

Figure S3. Promoter binding of p65 transactivates miR-125b-1 gene in biliary epithelial cells in response to LPS stimulation. (A) The schematic diagram shows two potential binding sites in the putative promoter element of mir-125b-1 gene. ChIP analysis revealed increased binding of p65 to the binding site at -1059, but not at -2455, of mir-125b-1 promoter element in cells following stimulation. (B) H69 cells were transfected with various luciferase reporter constructs spanning the potential p65 binding sites of the mir-125b-1 promoter. The transfected cells were exposed to LPS in the presence or absence of SC-514. , p < 0.05 t test vs nonstimulated cells; #, p < 0.05 t test vs LPS-stimulated cells.

Figure S4. Promoter binding of p65 transactivates mir-21 gene in biliary epithelial cells in response to LPS stimulation. (A) The schematic diagram shows two potential binding sites in the putative promoter element of mir-21 gene. ChIP analysis revealed increased binding of p65 to the binding site at +1395 of mir-21 promoter element in cells following stimulation. Although the two potential binding sites for NF-B subunit p65 are adjacent to each other, a stronger signal for the binding site at +1395 was detected. (B) H69 cells were transfected with various luciferase reporter constructs spanning the potential p65 binding sites of mir-21 promoter. The transfected cells were exposed to LPS in the presence or absence of SC-514. , p < 0.05 t test vs non-stimulated cells; #, p < 0.05 t test vs LPS-stimulated cells.

Figure S5.

Promoter binding of p65 transactivates C3orf9 (mir-23b-27b-24-1) gene in

biliary epithelial cells in response to LPS stimulation. (A) The schematic diagram shows one potential binding sites in the putative promoter element of C3orf9 gene. ChIP analysis revealed increased binding of p65 to the binding site at -1254 of C3orf9 promoter element in cells following stimulation. (B) H69 cells were transfected with various luciferase reporter constructs spanning the potential p65 binding sites of the C3orf9 promoter. The transfected cells were exposed to LPS in the presence or absence of SC-514. , p < 0.05 t test vs non-stimulated cells; #, p < 0.05 t test vs LPS-stimulated cells.

Figure S6. Promoter binding of p65 transactivates the mir-30b gene in biliary epithelial cells in response to LPS stimulation. (A) The schematic diagram shows one potential binding sites in the putative promoter element of mir-30b gene. ChIP analysis revealed increased binding of p65 to the binding site at -338 of mir-30b promoter element in cells following stimulation. (B) H69 cells were transfected with various luciferase reporter constructs spanning the potential p65 binding sites of the mir-30b promoter. The transfected cells were exposed to LPS in the presence or absence of SC-514. , p < 0.05 t test vs non-stimulated cells; #, p < 0.05 t test vs LPS-stimulated cells.
