Hepatoprotection of a Standardized Extract of Cultured Lentinula edodes Mycelia against Liver Injury Induced by Ischemia-Reperfusion and Partial Hepatectomy. Nutrients 2024; 16:256. [PMID: 38257149 PMCID: PMC10820669 DOI: 10.3390/nu16020256] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2023] [Revised: 01/08/2024] [Accepted: 01/11/2024] [Indexed: 01/24/2024] Open
Abstract
A standardized extract of cultured Lentinula edodes mycelia (ECLM, AHCC®) has been shown to have beneficial effects on organ metabolism. ECLM has been indicated to have liver protective properties by suppressing inflammatory responses. The pathogenesis of hepatic ischemia-reperfusion injury is thought to involve the induction of inflammatory mediators. However, whether ECLM affects inflammatory mediators caused by warm hepatic ischemia-reperfusion injury and partial hepatectomy (HIRI+PH) has not been clarified. In this study, we evaluated the protective effects of ECLM against liver damage caused by HIRI+PH. Rats were fed a normal diet (HIRI+PH) or a normal diet with 2% ECLM (HIRI+PH and ECLM) for ten days, then the liver and duodenal ligament were clamped and subjected to 15 min of hepatic ischemia. After 70% hepatectomy, the inflow occlusion was released, and liver and blood samples were collected at 3, 6, and 24 h. The effect of ECLM on mortality induced by 30 min of ischemia and hepatectomy was evaluated. The results showed that ECLM attenuated pathological liver damage, including apoptosis, in the rats treated with HIRI+PH, and decreased serum aminotransferase activity; ECLM decreased mRNA levels of the inflammation-related genes inducible nitric oxide synthase and C-X-C motif chemokine ligand 1, and increased mRNA levels of interleukin 10, an anti-inflammatory cytokine; ECLM increased hepatocyte growth factor mRNA levels and Ki-67 labeled nuclei in the liver at 24 h; ECLM significantly reduced HIRI+PH-induced mortality. In conclusion, ECLM may prevent HIRI+PH-induced liver injury in part by suppressing various inflammatory responses and promoting liver regeneration.

Carbohydr Polym 2020; 256:117545. [PMID: 33483054 DOI: 10.1016/j.carbpol.2020.117545] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Revised: 12/10/2020] [Accepted: 12/17/2020] [Indexed: 12/12/2022]
Abstract
The purpose of this study was to investigated the potential role of gut microbiota in protecting the intestinal barrier and improving nutritional metabolism in 5-FU-treated S180 tumour-bearing mice after treatment with oyster polysaccharide (CHP). CHP, with an α-(1→4) d-linked glucose backbone and (→4,6)-α-d-Glc-(1→) branches every 4.7 residues on average, increased the villus height, crypt depth, mucosa thickness, villus surface area and V/C ratio; decreased the expression of IL-1β, IL-6, and TNF-α; and even restored the TP, ALB, PA, TRF, IgA, IgM and IgG levels to normal levels. All these factors are related to CHP increasing the propionic acid- and butyric acid-producing microorganisms and decreasing the production of Bacteroides, Prevotellaceae_UCG-001 and Rikenellaceae_RC9_gut_group, thus affecting the TLRs signalling pathway. In conclusion, CHP attenuates 5-FU-induced intestinal mucositis and malnutrition by regulating gut microbiota, and can improve the prognosis of patients receiving chemotherapy.
