Palma-Duran et al., Metabolism, 2018 Jun. [67]50 normoglycemic NAFLD and 58 healthy adults (age, sex, and BMI matched)Elevated AGEs/sRAGE ratio was associated with NAFLDAGEs (CML) higher, sRAGE levels lower, and AGEs/sRAGE ratios were higher in the NAFLD
Mehta et al., PLoS One, 2018 Jun. [68]340 obese patients with metabolic syndromeCertain polymorphisms of RAGE gene are indicators of NASH in obese peopleRetrospective study
Only four polymorphisms were tested
Zelber-Sagi et al., Dig Liver, Dis, 2017 May [63]55 patients with fatty liver diagnosed by ultrasound (age 26–64)sRAGE levels have negative correlation with liver damageSerum sRAGE levels have negative association with fatty liver and positive correlation with fiber and vegetables consumption
Kan et al., J Clin Lab Anal, 2015 Nov. [69]90 NBNC-HCCAGE could discriminate NBNC-HCC from NASHNBNC-HCC patients had higher serum levels of AGE, compared to the NASH and control subjects
56 NASH
27 control subjects
Santilli et al., Vascular Pharmacology, 2015 Sep. [70]110 patients with FCHL, MS, and both FCHL plus MSNAFLD patients had significantly lower plasma esRAGE irrespective of underlying metabolic abnormality (FCHL or MS)Cross-sectional study
Lower levels of IL-10 and adiponectin and higher CD40 ligand, endogenous thrombin potential, and oxidized LDL in NAFLD patients
Su et al., Medicine (Baltimore), 2015 Aug. [71]300 cancer-free casesSNP rs1800625 of RAGE gene increases risk of HCC but has an inverse association with HCC progression5 common polymorphisms of RAGE gene were tested
265 HCC patients
D’Adamo et al., Free Radic Res, 2013 Mar. [72]Obese prepubertal children with NAFLDVitamin E supplementation increased the levels of esRAGE after 6-month treatmentVitamin E could potentially be a treatment in obese children with NAFLD
(i) 24 children received vitamin E supplementationVitamin E supplementation decreased oxidative stress and improved cardiometabolic alterations
(ii) 21 age- and sex-matched received life-style intervention
Gaens et al., Journal of Hepatology, 2012 Mar. [73]74 obese individualsCML and CML upregulated RAGE-dependent inflammatory response associated with NAFLDIn vitro model of steatosis used
CML accumulation associated with increased gene expression of proinflammatory cytokines
D’Adamo et al., Antioxidants and Redox signaling, 2011 Mar. [74]140 prepubertal obese childrenesRAGE and sRAGE levels were significantly lower in obese prepubertal children affected by liver steatosis compared with the group without liver steatosisDefinition of liver steatosis by ultrasound instead of the gold-standard invasive liver biopsy
71 boys and 69 girls aged between 6 and 10 years
Kimura et al., J Gastroenterol, 2010 Jul. [75]43 patients with dyslipidemia and biopsy-proven NASHAtorvastatin reduces the serum levels of AGEsAGEs are useful biomarkers for the attenuation of NASH
Yilmaz et al., Clin Biochem, 2009 Jun. [76]40 NASHPatients with NASH (definite and borderline) had lower plasma levels of sRAGE
8 borderline NASH
9 simple fatty liver
14 healthy controls
Hyogo et al., J Gastroenterol Hepatol, 2007 Jul. [77]66 NASHThe serum glyceraldehyde-derived AGE level may be a useful biomarker for NASHConstant increase in glyceraldehyde-derived AGEs could potentially contribute to the pathogenesis of NASH
10 simple steatosis
30 controls
