Background Metabolic dysfunction-associated steatotic liver disease (MASLD), previously non-alcoholic fatty (NAFLD), is a leading cause of chronic worldwide. In 20%–30% MASLD patients, the progresses to metabolic steatohepatitis (MASH, NASH) which can lead fibrosis/cirrhosis, failure as well hepatocellular carcinoma (HCC). Here we investigated role histidine-rich glycoprotein (HRG), plasma protein produced by hepatocytes, in MASLD/MASH progression and HCC development. Methods The HRG was morphological, cellular, molecular biology approaches (a) knock-out mice (HRG −/− mice) fed on CDAA dietary protocol or MASH related diethyl-nitrosamine/CDAA hepatocarcinogenesis, (b) THP1 monocytic cells treated with purified HRG, (c) well-characterized cohorts patients without HCC. Results non-neoplastic settings, murine clinical data indicate that increases significantly parallel progression. particular, higher levels were detected subjects extensive fibrosis/cirrhosis. When submitted pro-carcinogenic protocol, showed significant decrease volume number nodules relation decreased infiltration macrophages producing pro-inflammatory mediators, including IL-1β, IL-6, IL-12, IL-10, VEGF impaired angiogenesis. histopathological analysis (H-score) MASH-related positivity peritumoral tissue correlates lower overall patient survival an increased recurrence. Moreover, increase cirrhotic (F4) carrying vs. F0/F1 patients. Conclusion Murine plays supporting specific population tumor-associated response pro-angiogenetic capabilities critically support cancer cell survival. Furthermore, our suggest possible prognostic predictor MASLD/MASH-related HCCs.

Non-alcoholic fatty liver disease (NAFLD) is a challenging to interfere with and represents potential long-term risk factor for hepatic fibrosis cancer. The Xiezhuo Tiaozhi (XZTZ) formula, water extract from crude herbs, has been widely used as an anti-NAFLD agent through clinical observation. However, the underlying pharmacological mechanisms of XZTZ formula its impact on pathways against NAFLD have not elucidated. Our study aims investigate effects regulatory treat NAFLD. possible active components were identified using ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) molecular docking. To further explore mechanisms, forty-eight 6-week-old male C57BL/6J mice given individual attention high-fat high-sugar diet (HFHSD) or relevant control (Ctrl) diets 16 weeks successfully construct mouse model.

Abstract The helminth defense molecules (HDM) are a family of immune regulatory peptides exclusively expressed by trematode worms. We have previously demonstrated that in vivo FhHDM‐1, the archetypal member HDMs, regulated macrophage responses to inflammatory ligands, thereby ameliorating progression immune‐mediated tissue damage several murine models disease. Accordingly, we postulated an understanding structure–function relationship HDMs would facilitate identification minimal bioactive peptide, which represent more synthesizable, cost‐effective, potent biotherapeutic. Thus, using combination bioinformatics, structural analyses, and cellular assays discovered 40 amino acid peptide derivative termed FhHDM‐1.C2. This contains 12 motif at its N‐terminus, facilitates interaction uptake, amphipathic α‐helix within C‐terminus, is necessary for lysosomal vATPase inhibitory activity, with both regions linked short unstructured segment. FhHDM‐1.C2 exhibits enhanced regulation function, compared full‐length prevention relapsing–remitting‐experimental autoimmune encephalomyelitis (EAE) when administered prophylactically or therapeutically. protective effect not associated global suppression, places as improved class biotherapeutics treatment diseases. Comparing from zoonotic trematodes revealed similar capacity regulation. These important new advances into lead HDM encourage further prospecting screening broader discovery novel immune‐biotherapeutics.

Immune cells are central mediators of the immune response and play critical roles in pathogenesis progression liver diseases. Understanding specific contributions to disease is essential for developing targeted therapeutic strategies. In this study, we employed a two-sample Mendelian randomization (MR) approach explore potential causal relationships between peripheral cell phenotypes diseases, using genetic instrumental variables from large-scale genome-wide association studies (GWAS). Applying inverse variance weighted (IVW) methods, identified that monocyte count(odds ratio (OR) 0.81; 95% confidence interval (CI) 0.74-0.90; P = 5.95 × 10- 5, PFDR 3.57 4), CD3- lymphocyte/lymphocyte (OR 0.59, CI 0.45-0.79; 3.29 4, 5.92 3) SSC-A (Side Scatter Area) on Natural Killer (NK) 0.89, 0.82-0.95; 1.37 3, 0.0396) acted as protective factors against alcoholic disease. Similarly, trait HLA DR++ monocyte/monocyte was associated with lower risk autoimmune hepatitis 0.56, 0.41-0.79; 7.42 0.0475).
