Article Title: Pulpitis Transiently Affect Hepatic Bone Morphogenetic Protein 9 Expression by Lipopolysaccharide
doi: 10.1016/j.identj.2026.109435
Figure Lengend Snippet: UNC0642 restored BMP9 expression in C57 mice and binding of H3K9me2 to the promoter region of BMP9 gene. (A) The expression of BMP9 in the DMSO-PO group was decreased, whereas that in the UNC0642-PO group was upregulated and similar to that in the DMSO control group (WB). (B) The RT-qPCR results are consistent with the IHC results. (C and D) The WB results were consistent with the IHC results ( n = 6). The groups 1 to 3 correspond to the DMSO group, DMSO-PO group, and UNC0642-PO group, respectively. (E) After stimulation of mHSCs with P.g LPS, the enrichment rate of H3K9me2 in the promoter region of BMP9 gene was significantly increased (ChIP) ( n = 3). (F) Full-text pattern diagram. LPS from pulpitis reached the liver through the bloodstream, stimulating hepatic stellate cells and regulating the expression of BMP9 in the liver via H3K9 dimethylation. DMSO represents the working fluid of inhibitors in vivo: DMSO + 40% PEG300 + 5% Tween80 + double-distilled H2O; LPS, samples stimulated with P.g LPS; me2, dimethylation; NS, normal sample; PO, pulp opening. Data are presented as mean ± SD; * P < .05. Black scale: 100 μm, white scale: 50 μm.
Article Snippet: For in vitro experiments, mHSCs were cultured into 6-cm dishes or 24-well plates and divided into a dimethyl sulfoxide (DMSO) control group; DMSO + LPS group; and 0.5, 1, and 5 μM UNC0642 (Selleck) groups.
