Abstract

INTRODUCTION AND OBJECTIVES

Metabolic-associated fatty liver disease (MAFLD) is defined by steatosis in more than 5% of hepatocytes without other liver diseases. Patients with this disease can progress to multiple stages like liver fibrosis, cirrhosis, and hepatocellular carcinoma. miRNAs are single-stranded molecules that regulate metabolic homeostasis; their differential expression postulates them as potential circulating biomarkers for MAFLD. Previous research reported that hsa-miR-140-5p, hsa-miR-148-5p, and hsa-miR-122-3p have a differential expression in patients with MAFLD. This study aimed to investigate the correlation between liver hsa-miR-140-5p, hsa-miR-148-5p, and hsa-miR-122-3p and serum biomarkers CK-18, APOB, IL-6, IL-32, and TNF-α in patients with MAFLD compared with control patients.

MATERIALS AND METHODS

A cross-sectional study was carried out with 16 patients of both sexes, aged between 18-60 years, to determine the association between the levels of hsa-miR-140-5p, hsa-miR-148-5p, and hsa-miR-122-3p with MAFLD in liver biopsies of patients who underwent laparoscopic cholecystectomy.

RESULTS

Twelve patients presented MAFLD, four without hepatic steatosis. Circulating levels of CK-18 showed a significant difference in patients with MAFLD, and a strong correlation was found between hsa-miR-122-3p, hsa-miR-140-5p, and hsa-miR-148b-5p versus the CAP value.

CONCLUSION

There is a correlation between elevated tissue expression of hsa-miR-122-3p, hsa-miR-140-5p, and hsa-miR-148b-3p with plasma levels of CK-18 in patients with simple steatosis compared with patients without the disease.

摘要

简介和目的

代谢相关脂肪性肝病（MAFLD）定义为超过 5%的肝细胞发生脂肪变性，且无其他肝病。此类患者可进展至肝纤维化、肝硬化和肝细胞癌等多个阶段。miRNAs 是调节代谢稳态的单链分子，其差异性表达使其成为 MAFLD 潜在的循环生物标志物。既往研究报道 hsa-miR-140-5p、hsa-miR-148-5p 和 hsa-miR-122-3p 在 MAFLD 患者中存在差异性表达。本研究旨在探讨 MAFLD 患者肝组织 hsa-miR-140-5p、hsa-miR-148-5p 和 hsa-miR-122-3p 与对照组患者血清生物标志物 CK-18、APOB、IL-6、IL-32 和 TNF-α 之间的相关性。
