ABSTRACT
The incidence of nonalcoholic fatty liver disease (NAFLD) is increasing worldwide and the age of onset gradually gets younger. However, specific therapeutic interventions are lacking. The exact mechanism of NAFLD has not yet been well elucidated. Recent studies indicate that adiponectin (APN) is an adipokine with anti-inflammatory activity and is considered a hepatic protector, which plays a central role in the pathogenesis of NAFLD. Research on APN actions in NAFLD is popular around the world. This article summarizes the mechanism of APN actions in NAFLD, briefly describes the relationship of APN with nonalcoholic steatohepatitis and NAFLD-related hepatic fibrosis, and reviews related clinical studies. It is suggested that APN holds promise as a novel therapeutic target in the treatment of NAFLD and further research into the signaling pathway of APN would lead to a better understanding of its action mechanism and can provide a novel strategy for the treatment of NAFLD.
ABSTRACT
As a novel research tool,metabolomics technology can reveal the differences in metabolic profiles during the development and progression of hepatocellular carcinoma (HCC),so it has been widely applied for research on HCC biomarkers.The significance of metabo-lomics in the diagnosis of HCC is briefly described,and the metabolomics research aiming at the discovery of HCC biomarkers,including an-imal experiments and clinical studies of metabolites in the serum,urine,and liver tissue,is reviewed.It is pointed out that analyzing and monitoring metabolites in the development and progression of HCC is of great significance for individualized treatment.
ABSTRACT
Hepatocellular carcinoma (HCC)is one of the most fatal malignant tumors worldwide.As an important part of cutting-edge re-search fields,proteomics has been widely used in the studies of related diseases and has currently become a crucial experimental approach to research on HCC.Significantly expressed proteins can be identified as potential biomarkers for early diagnosis and targets for therapeutic drugs for HCC.Moreover,they can be used for prediction of the recurrence and prognosis of HCC,as well as for investigation of pathogene-sis of the disease.The proteomic results from worldwide clinical studies of HCC are summarized,and it is suggested that the clinical applica-tion of results of basic research on HCC proteomics will bring great benefit to the diagnosis and treatment of HCC.
ABSTRACT
Objective To investigate the effect and mechanism of Artemisia Argyi extracting solution on anti-hepatic fibrosis.Methods Twenty-four experimental Wistar rats were randomized into four groups:Artemisia group,Danshen group,physiological saline group,and blank control group,with 6 in each.The Artemisia group was treated with 20% Artemisia Argyi extracting solution,the Danshen group with Danshen (salvia) solution,and the physiological saline group with physiological saline by gavage,20ml/kg.After treating three times per day for 3 days,sera were obtained and made a mixture with DMEM to be volume fraction as 5%,10%,and 20%.Effect of different volume fraction of extracting solution on TGF-?1 Smad3 and Smad7 mRNA and protein were detected.Results After treating with 5%,10% and 20% Artemisia Argyi extracting solution contained rat serum for 24h,contrasted to the black control group,the expression of TGF-?1 mRNA level was (0.82?0.03),(0.72?0.03) and (0.67?0.04) times,and the expression of TGF-?1 protein was (0.66?0.09),(0.34?0.05) and (0.31?0.07) times respectively;contrasted to the physiological saline group,the expressions of TGF-?1 mRNA and protein were significantly decreased (P
