Dissecting the dynamics of cell death pathways in Hirschsprung's disease: a comparative analysis of viable and non-viable cells under proinflammatory conditions.

Purpose: The present study explores the dynamics of cell death in Hirschsprung's disease (HSCR) and control (CO) groups under inflammatory stress conditions.

Methods: Using flow cytometry, we analyzed intestinal colonic organoid cultures derived from the ganglionic segment of the HSCR and CO groups. Our analysis focused on the quantification of RIPK1-independent and RIPK1-dependent apoptosis, as well as necroptosis in both viable and non-viable cells under acute and chronic inflammatory stress.

Biliatresone induces cholangiopathy in C57BL/6J neonates.

Exposure to plant toxins or microbiota that are able to digest common food ingredients to toxic structures might be responsible for biliary atresia (BA). An isoflavonoid, biliatresone is known to effectively alter the extrahepatic bile duct (EHBD) development in BALB/c mice. Biliatresone causes a reduction of Glutathione (GSH) levels, SOX17 downregulation and is effectively countered with N-Acetyl-L-cysteine treatment in vitro.

Extrahepatic Bile Duct and Gall Bladder Dissection in Nine-Day-Old Mouse Neonates.

The dissection of murine neonatal bile ducts has been described as difficult. The main aim of the described standard operating procedure is the isolation of the extrahepatic bile duct (EBD) in mouse neonates without damaging the bile duct during preparation. Because of its exceptionally close preparation compared to the cholangiocytes cell line and harvesting of the entire extrahepatic bile duct system (EBDS), the described approach is extremely useful in researching animal models of newborn bile duct disorders, such as biliary atresia.
