A rare syndrome variably characterized by chronic cholestasis due to paucity of intrahepatic bile ducts, peripheral pulmonary artery stenosis, vertebrae segmentation anomalies, characteristic facies, posterior embryotoxon/anterior segment abnormalities, pigmentary retinopathy, and dysplastic kidneys.
Verteporfin disrupts YAP/TAZ-TEAD interactions while FXR agonists (obeticholic acid) promote bile acid homeostasis, synergistically reducing hepatocyte hyperproliferation and promoting proper bile duct architecture through balanced Hippo signaling
UDCA reduces hepatotoxicity while novel small molecule allosteric modulators directly enhance NOTCH2 receptor sensitivity to available ligands, amplifying residual Notch signaling in bile duct epithelial cells despite JAG1/NOTCH2 mutations
Silymarin from Silybum marianum enhances DLL4 (Delta-like ligand 4) expression in hepatocytes through NRF2-mediated transcriptional activation, providing alternative Notch signaling pathway activation to compensate for deficient JAG1-mediated signaling in Alagille syndrome
Anti-miR-200 oligonucleotides reduce microRNA-200 family expression, allowing ZEB1/ZEB2-mediated mesenchymal-epithelial transition in hepatic progenitor cells, promoting their differentiation into functional cholangiocytes despite impaired Notch signaling
Triphala polyphenols (gallic acid, ellagic acid, chebulic acid) activate TFEB and enhance lysosomal biogenesis, promoting clearance of misfolded NOTCH2 proteins and reducing ER stress in cholangiocytes, potentially restoring partial receptor function
Paeoniflorin and other bioactive compounds from Goshajinkigan (Japanese Kampo formula) activate FOXM1 transcription factor, promoting cholangiocyte proliferation and bile duct morphogenesis through upregulation of CDC25B and AURKA kinases
Mesenchymal stem cell-derived extracellular vesicles engineered to carry functional JAG1 protein target hepatic stellate cells via integrin-mediated uptake, restoring local Notch signaling in the periportal niche and promoting bile duct formation
