Abstract
Background and Aim. Redox equilibria are critical for life, but the biomarkers of redox status are currently unavailable. Gamma-glutamyltransferase (GGT) is an essential factor for modulating redox equilibrium through glutathione. In clinical practice, increased circulating GGT activity is used as a hepatobiliary disease biomarker. However, increased circulating GGT activities have also been observed in cancers, heart disease, diabetes, hyperuricemia, inflammation, renal insufficiency, and other diseases, explained by its role in maintaining redox equilibrium inside and outside cells. Previous studies on GGT were mainly limited to one type of disease at one time. In the current study, we systematically compared the GGT levels in 44 different human diseases to test if it could serve as a redox status biomarker in blood circulation. Methods. The clinical GGT data from 168,858 patients with 44 diseases and 132,357 healthy control in the clinical laboratory of our hospital over the past five years were retrieved. All data were analyzed with SPSS, RStudio V.1.3.1073, and python libraries 3.8. Results. Thirty-eight out of 44 diseases had significantly increased (
) circulating GGT activities, whereas gastric cancer, anemia, renal cyst, cervical cancer, preeclampsia, and knee-joint degenerative diseases had significantly decreased (
) GGT activities compared to the healthy control. ROC analyses showed that GGT was an excellent biomarker for liver cancer (
), pancreatitis (
), or hepatic encephalopathy (
). All pancreas-related diseases had more than 8-fold increases in GGT activity span than the healthy control, while pancreatic cancer had a 12-fold increase (1021 U/L vs. 82 U/L). The knee-joint degenerative disease had the lowest median and narrowest GGT activity range (63 U/L). Furthermore, most diseases’ lowest to highest GGT activities were beyond the healthy control in both directions. Conclusions. Thirty-eight out of 44 diseases were in overall oxidative states defined by the increased GGT median values. In contrast, knee-joint degenerative disease, gastric cancer, anemia, renal cyst, cervical cancer, and preeclampsia were in overall antioxidative states. Moreover, most diseases swing between oxidative and antioxidative states, evidenced by the increased lowest to highest GGT activity ranges than the healthy control. Liver- and pancreas-related abnormalities were responsible for significantly increased GGT activities. Our overall results suggested that circulating GGT was a redox status biomarker.

Studies on the Antiliver Injury of Effective Parts from Saururus chinensis by Rats and Mice Model In Vivo. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2022; 2022:7821724. [PMID: 35518346 PMCID: PMC9064534 DOI: 10.1155/2022/7821724] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/17/2021] [Revised: 03/14/2022] [Accepted: 03/29/2022] [Indexed: 11/17/2022]
Abstract
The aim of this study was to evaluate the pharmacodynamics of the effective parts from Saururus chinensis (EPS) in vivo. The antihepatic fibrosis and injury effects of EPS were investigated with the following four model animals including the effect on Wistar rats with liver fibrosis induced by complex factors, mice with acute liver injury induced, respectively, by carbon tetrachloride and alcohol, and Sprague-Dawley (SD) rats with acute liver injury caused by D-galactosamine hydrochloride. The pharmacodynamics results showed that the rats’ oral administration of EPS can significantly inhibit the formation of liver fibrosis in rats caused by complex factors and has significant preventive and therapeutic effects on acute liver injury caused by various factors as shown by decreased levels of serum biochemical indicators and improved pathological grade. Taken all together, our findings showed that EPS exhibits potent activities and should be considered a good option and an additional source of natural compounds for the treatment of hepatic fibrosis and hepatic injury.

Ye L, Yu Y, Zhao Y. Icariin-induced miR-875-5p attenuates epithelial-mesenchymal transition by targeting hedgehog signaling in liver fibrosis. J Gastroenterol Hepatol 2020; 35:482-491. [PMID: 31617598 DOI: 10.1111/jgh.14875] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 09/18/2019] [Accepted: 09/23/2019] [Indexed: 12/13/2022]
Abstract
BACKGROUND Hepatic fibrosis is the final endpoint for most chronic liver diseases and remains a significant public health problem worldwide. Icariin, a naturally occurring flavonol glucoside, has been reported to exhibit protective effects on liver injury and alleviate liver fibrosis. However, the underlying detail molecular mechanism is not fully revealed. METHODS Mouse primary hepatic stellate cells (HSCs) and carbon tetrachloride (CCL4 )-induced liver fibrosis model in mice were used as in vitro and in vivo models in this study. The expression levels of miR-875-5p were detected by quantitative reverse transcription-PCR. The validation of the direct target of miR-875-5p was through dual-luciferase reporter assay and western blotting assay. The cell proliferation and cell mobility were determined using MTT assay and Transwell migration assay, respectively. RESULTS We found that icariin inhibited epithelial-mesenchymal transition and collagen protein section of HSCs. Icariin exerted hepatoprotective effects on mice model of CCL4 -induced liver fibrosis. Our further results revealed that miR-875-5p was downregulated in human cirrhosis tissues and activated murine HSCs. Icariin induced miR-875-5p upregulation and subsequently decreased glioma-associated oncogene homolog 1 (GLI1) expression through direct binding to the three prime untranslated region of GLI1 mRNA. CONCLUSION Our study highlighted the potential therapeutic application of icariin for liver fibrosis management.

Tartary buckwheat extract alleviates alcohol-induced acute and chronic liver injuries through the inhibition of oxidative stress and mitochondrial cell death pathway. Am J Transl Res 2020; 12:70-89.

Abstract
Alcohol use disorder (AUD) is an enormous public health problem that poses significant social, medical, and economic burdens. Under AUD, the liver is one of the most adversely affected organs. As current therapies and protective drugs for AUD-mediated liver injury are very limited, the prevention and therapy of alcoholic liver disease are urgently needed. The present study aims to investigate the beneficial effects of tartary buckwheat extract (TBE), the important component of Maopu tartary buckwheat liquor, on both alcoholic-induced acute and chronic liver injuries. We show that the TBE administration, similar to curcumin, significantly reduces the elevated serum aspartate aminotransferase and alanine aminotransferase levels, improves liver index, alleviates the elevated contents of hepatic malondialdehye, and restores the decreased contents of hepatic glutathione both in acute and chronic liver injuries in alcohol-exposed rats. Furthermore, histopathological analyses show that a medium dose of TBE (16.70 ml/kg body weight) alleviates hepatocyte morphology changes in both acute and chronic alcohol exposure models. We also show the protective effects of TBE on the cell death rates of alcohol-exposed primary cultured hepatocytes, HepG2 hepatoma, and Huh 7 hepatoma cells. Furthermore, we demonstrate that TBE exerts hepatoprotection partly through inhibiting the mitochondrial cell death pathway by reducing cytochrome c release, caspase-9 and -3 activities, and the number of TUNEL-positive cells. These effects of TBE were accompanied by enhanced levels of Bcl-2 and Bcl-xL and autophagic cell death pathway by reducing Beclin-1 expression, as well as through promoting its anti-oxidant capacity by suppressing reactive oxygen species production. This study demonstrates, for the first time, the protective effect of TBE against alcohol-induced acute and chronic liver injury in vivo and in vitro. Given the dietary nature of tartary buckwheat, pueraria, lycium barbarum, and hawthorn, the oral intake of TBE or liquor contained TBE, e.g., Maopu Tartary buckwheat liquor, compared with pure liquor consumption alone, may have the potential to alleviate alcoholic-induced liver injuries.
