Summary: The study revealed that liver injury affects the function and expression of retinal Mrp1 in rats, activating the p38 MAPK pathway. These findings suggest that controlling liver function may help prevent the development of retinal diseases.

Summary: The study found that ischemic preconditioning can reduce myocardial infarct size, apoptotic indices, arrhythmia, and incidence of ventricular fibrillation in cirrhotic cardiomyopathy rats. Metformin and Cyclosporin-A can exert cardioprotective effects by balancing pAMPK and apoptosis in mitochondria.

Summary: Anatomically resolved maps of small molecules reveal distinct spatial patterns throughout the gut of colonized and germ-free mice, which can be associated with specific microorganisms. The map of the longitudinal metabolome in the gut of healthy mice shows a shift from amino acids to organic acids, vitamins, and nucleotides along the gut. Comparisons between colonized and germ-free mice help identify the origin of metabolites and suggest specific microbial influence on the metabolome.

Summary: Bile duct ligation in mice is a classical method for studying cholestatic fibrosis. This study aimed to evaluate the correlation between pathological changes and multiparameter MRI characteristics of liver fibrosis in a BDL mouse model. Results show that MRI parameters correlate with hepatic fibrosis rate and can be used for detecting cholestatic fibrosis.

Summary: Thyroid hormone plays an important role in liver metabolism, and its levels are disrupted in liver failure and hepatic encephalopathy. This study investigates the gene expression changes in the thyroid glands of a bile duct ligation mouse model and confirms the alteration in thyroid function-related genes. Increased levels of free T4 and TSH are also observed in the blood of the mouse model.

Summary: In this study, the differences in effects between fully ripe fruits (RF) and greenish fruits starting to ripen (GF) of Forsythia suspensa were compared using a bile duct ligation (BDL)-induced cholestasis rat model. The study found that RF had better results in addressing toxic bile acids accumulation and related pathological conditions caused by BDL. The underlying mechanism may be related to the interventions of gut microbiota.

Summary: The composition of gut microbiota in rats was studied under bile duct ligation or biliary drainage. The bile duct obstruction was induced by extrahepatic bile duct ligation, while bile deficiency was caused by draining the bile via a percutaneous biliary drainage catheter. The DNA extracted from fecal samples was sequenced and analyzed. The results showed that bile duct obstruction altered the composition of gut microbiota, which was restored after biliary drainage. The study also identified the potential functions of the different microorganisms. Overall, the study highlights the significant changes in gut microbiota and their potential functions under bile duct-related conditions.

Summary: Amuc is a pili-like protein found abundantly on the outer membrane of Akkermansia muciniphila, and has been shown to have anti-obesity effects through TLR2 activation. This study used TLR2 knockout mice to investigate the mechanism of action. The results demonstrated that Amuc decreased body weight and lipid deposition by regulating fatty acid metabolism, reducing bile acid synthesis, and strengthening the intestinal barrier function. The study also found that Amuc altered the gut microbiota composition, which may contribute to its effects on the intestinal barrier in high-fat diet-induced mice. These findings support the potential use of Amuc as a therapy for obesity-associated metabolic syndrome.

Summary: In this study, researchers investigated the effects of triptolide (TP), a compound found in Tripterygium wilfordii Hook.f, on cholestasis-induced liver injury. They found that TP reduced liver enzyme levels and necrosis in a mouse model of common bile duct ligation (BDL) cholestasis. TP also inhibited cholangiocyte proliferation and alleviated BDL-induced hepatic fibrosis and inflammation by reducing the expression of RelB.

Summary: The study shows that increased expression of PRL-1 through CP-MSC transplantation promotes liver regeneration, enhances liver function, increases hepatocyte proliferation, and regulates CP-MSC migration. Silencing of PRL-1 significantly reduces its dual effects on hepatocyte proliferation and CP-MSC migration.

Summary: Bile components are important in maintaining gut microbiota homeostasis. In cholestasis, impaired bile secretion leads to liver injury. However, it is unclear whether gut microbiota plays a role in cholestatic liver injury.

Summary: Cirrhotic patients often experience cirrhotic cardiomyopathy (CCM), which is studied in detail through animal models of bile duct ligation (BDL) and a second surgery. The study reveals delayed adaptability, impaired contractility at rest, reduced contractile reserve, increased creatine and transaminase levels, myocardial fibrosis, macrophage infiltration, systemic inflammation, altered expression of peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC1a), and increased expression of caspase-3. Structural changes in the myocardium are observed after 8 weeks. Transient myocardial insufficiency and secondary organ dysfunction occur after the second surgery.

Summary: By constructing variant communities of a complex defined microbial community, we found that removing specific strains occupying the bile acid 7a-dehydroxylation niche resulted in significant changes in the community composition and function. Strains that are functionally redundant within a niche can have differential impacts outside the niche, leading to unpredictable effects on unrelated community-level phenotypes. This study highlights the complexity of the gut microbiome and the importance of understanding individual strain dynamics in the context of the entire community.
