Though rare, primary biliary cholangitis (PBC) and primary sclerosing cholangitis (PSC) account for 8-14% of liver transplants (LT) in North America and Europe and the journey of these patients across the peri-transplant period is unique. Equitable access to LT is an important challenge, as the MELD score and its derivatives inadequately reflect the morbidity and mortality related to these diseases failing to capture disease-specific complications, such as recurrent cholangitis, malignancy risk, severe portal hypertension, and sarcopenia. The waitlist experience is high-risk, prolonged and a distinct form of “MELD purgatory”. Once barriers to access are overcome, post-transplant outcomes are generally excellent, however disease recurrence affects 15-35% at 5 to 10 years post-LT with increasing rates over time. Diagnosing recurrence is challenged by a broad differential for post-transplant biliary injury, and the risk factors for its development remain controversial. While post-LT use of ursodeoxycholic acid in PBC is clearly beneficial, no effective medical therapy currently exists for recurrent PSC. A heightened focus on control of inflammatory bowel disease activity is critical as a potentially important modifiable risk factor for rPSC, including with escalation of medical therapy as needed and timely colectomy when indicated. This review outlines the journey for patients with PBC and PSC, from transplant listing to post-transplant management, emphasizing the need for unique and tailored approaches to optimize outcomes and long-term survival.

Backgrounds &Aims: Hepatitis B virus (HBV)-related liver disease ranks as the seventh leading cause of mortality. Despite advances in prevention and treatment, global disparities in the burden of primary liver cancer (PLC) persist. We evaluate global trends in the prevalence, incidence, and death of HBV-related liver disease. Approach and Results: Data from the Global Burden of Disease Study 2021 evaluated acute HBV infection, HBV-related cirrhosis, and HBV-related liver cancer prevalence, incidence, and death. In 2021, there were 7.30 million cases of acute HBV, 283.64 million cases of HBV-related cirrhosis, and 288,110 cases of HBV-related PLC. HBV-related PLC accounted for 39% of the global incidence of PLC; Western Pacific had the highest rates for HBV-related PLC, with an incidence of 5.24 and a death rate of 4.38 per 100,000 population. Between 2000-2021, age-standardized incidence, prevalence, and death rates from HBV-related liver disease decreased; however, the incidence of HBV-related PLC rose in 65 countries from 2000 to 2021. In parallel, age-standardized prevalent rates from HBV-related PLC increased in Europe (Annual percent change [APC]: 0.77%, 95% confidence interval [CI] 0.72 to 0.81%) and the Americas (APC: 1.05%, 95%CI 1.00 to 1.10%). Conclusion: From 2000 to 2021, decreases in HBV-related liver disease incidence and prevalence were observed; however, more than one-third of countries showed an increase in the incidence of HBV-related PLC. These findings highlight the need for strengthened HBV treatment efforts to reduce the risk of liver cancer.

Targeting protein hyperSUMOylation halts cholangiocarcinoma progression by impairing cancer cell viability and tumor-stroma crosstalk

Andersen, Luke Boulter, Luis Bujanda, Pedro M. Rodrigues, Maria J. Perugorria, Jesus M. Banales
Background and Rationale: Cholangiocarcinoma (CCA) includes a diverse group of biliary malignancies with poor prognosis. Alterations in post-translational modifications contribute to disrupted protein dynamics, cellular disturbances, and disease. This study investigates the role of protein SUMOylation in cholangiocarcinogenesis and its potential as a therapeutic target. Approach and Results: Analysis of CCA tumors from four patient cohorts and CCA cell lines, revealed increased expression of the SUMOylation machinery genes SAE1 and UBE2I, regardless of the tumor’s molecular profile, resulting in elevated levels of SUMO1-conjugated proteins. Higher SAE1 and UBE2I levels were both indicative of unfavorable clinical outcomes. Deregulated SUMOylated proteins in CCA, mostly linked to cell proliferation, survival, and homeostasis, were identified through immunoprecipitation and mass spectrometry. Genetic (UBE2I-knockdown) and pharmacological (ML792 and SAMe) inhibition of SUMOylation effectively suppressed tumorigenesis in subcutaneous and oncogene-driven CCA models, reducing the presence of cancer-associated fibroblasts (CAFs) and increasing the recruitment of anti-tumor immune cells. In vitro, targeting SUMOylation induced CCA cell death and reduced cell proliferation, colony formation, and spheroid growth. Importantly, ML792 and SAMe did not adversely affect normal human cholangiocytes. Moreover, co-culture of wild-type or UBE2I-knockdown CCA cells with CAFs revealed that depleting SUMOylation in CCA cells impaired CAF cell growth and altered their protein secretome, ultimately disrupting CCA growth through a regulatory feedback loop. Conclusion: Aberrant SUMOylation drives CCA progression by enhancing cell survival, proliferation, and shaping the tumor microenvironment. Targeting SUMOylation shows potential in inhibiting CCA growth, representing a promising therapeutic strategy.

Background and Aims: Cholangiocarcinoma (CCA) is an aggressive malignancy arising from the biliary epithelium with limited therapeutic options and poor long-term survival rates. To address the limitations in CCA treatment, we investigated cell-targeted nanovesicles as a delivery platform for transcriptome-targeting therapeutics. Approach & Results: Milk-derived nanovesicles (MNVs) were loaded with short interfering RNAs targeting YAP, the downstream effector of the Hippo pathway; LCK, an upstream regulator of YAP; and tafazzin, a protein critical for the integrity of the inner mitochondrial membrane. These transcriptome-targeting nanovesicles (tMNVs) were decorated with a lipid-coupled RNA aptamer to epithelial cell adhesion molecule (EpCAM), including a tracking fluorophore. In vitro studies were conducted using multiple CCA cell lines. In vivo studies were performed using C57BL/6 and NOD/SCID mice to evaluate delivery and efficacy in both an immunocompetent syngeneic murine and a patient-derived xenograft (PDX) model. We demonstrated that tMNVs were selectively taken up by liver tumor cells, which was augmented by the incorporation of a targeting aptamer, and that MNVs loaded with siRNA effectively downregulated target gene expression, both in vitro and in vivo. Downstream effects of target gene inhibition were observed, including downregulation of YAP-TEAD target genes and an increase in reactive oxygen species production at the mitochondrial level. Administration of tMNVs targeting YAP, LCK, and tafazzin inhibited CCA growth and further synergized with chemotherapy in two preclinical CCA models. Conclusions: Herein, we show that aptamer-directed, nanovesicle-mediated targeting of YAP, LCK, and tafazzin potentiates chemosensitivity in two CCA models when delivered using aptamer-guided milk-derived nanovesicles.
