Multi-omics profiling of cholangiocytes reveals chromatin state dynamics during hepatic cystogenesis in polycystic liver disease (RNA-Seq BGI)

Project description:Through genome-wide profiling of chromatin dynamics, we revealed a profound increase of global chromatin accessibility and a switch from H3K9me3 to H3K9ac on cis-regulatory DNA elements of cyst-associated genes during cystogenesis. In an integrated epigenomic and transcriptomic analysis, we identified a transcription factor network associated with dynamic shifts in chromatin states. Functionally, we showed that inhibition of H3K9ac acetyltransferase or H3K9me3 demethylase restored chromatin states and gene expression program to slow cyst growth in PLD mice.

Targeting UBC9-mediated Protein Hyper-SUMOylation in Cystic Cholangiocytes Halts Polycystic Liver Disease in Experimental Models

Project description:Background & Aims: polycystic liver diseases (PLDs) are genetic disorders characterized by progressive development of multiple fluid-filled biliary cysts. Most PLD-causative genes participate in protein biogenesis and/or transport. Post-translational modifications (PTMs) are implicated in protein stability, localization and activity, contributing to human pathobiology; however, their role in PLD is unknown. Here, we aimed to unveil the role of protein SUMOylation in PLD and its potential therapeutic targeting. Methods: levels and function of SUMOylation, along with response to S-adenosylmethionine (SAMe, inhibitor of the SUMOylation enzyme UBC9) and/or short-hairpin RNAs (shRNAs) against UBE2I (UBC9), were evaluated in vitro, in vivo and/or in patients with PLD. SUMOylated proteins were determined by immunoprecipitation and proteomic analyses by mass spectrometry. Results: most SUMOylation-related genes were found overexpressed (mRNA) in polycystic human and rat liver tissue, as well as in cystic cholangiocytes in culture compared to controls. Increased SUMOylated protein levels were also observed in cystic human cholangiocytes in culture, which decreased after SAMe administration. Chronic treatment of polycystic (PCK: Pkdh1-mut) rats with SAMe halted hepatic cystogenesis and fibrosis, and reduced liver/body weight ratio and liver volume. In vitro, both SAMe and shRNA-mediated UBE2I knockdown increased apoptosis and reduced cell proliferation of cystic cholangiocytes. High-throughput proteomic analysis of SUMO1-immunoprecipitated proteins in cystic cholangiocytes identified candidates involved in protein biogenesis, ciliogenesis and proteasome degradation. Accordingly, SAMe hampered the proteasome hyperactivity in cystic cholangiocytes, leading to the activation the unfolded protein response (UPR) and stress-related apoptosis.
