الوصف: [Background and Aims]: The molecular mechanisms driving non-alcoholic fatty liver disease (NAFLD) are poorly understood; however, microRNAs might play a key role in these processes. We hypothesize that let-7d- 5p could contribute to the pathophysiol-ogy of NAFLD and serve as a potential diagnostic biomarker. ; [Methods]: We evaluated let-7d- 5p levels and its targets in liver biopsies from a cross- sectional study including patients with NAFLD and healthy donors, and from a mouse model of NAFLD. Moreover, the induction of let-7d- 5p expression by fatty acids was evaluated in vitro. Further, we overexpressed let-7d- 5p in vitro to corroborate the results observed in vivo. Circulating let-7d- 5p and its potential as a NAFLD biomarker was determined in isolated extracellular vesicles from human plasma by RT-qPCR. ; [Results]: Our results demonstrate that hepatic let-7d-5p was significantly up-regulated in patients with steatosis, and this increase correlated with obesity and a decreased expression of AKT serine/threonine kinase (AKT), insulin-like growth factor 1 (IGF1), IGF-I receptor (IGF1R) and insulin receptor (INSR). These alterations were corroborated in a NAFLD mouse model. In vitro, fatty acids increased let-7d-5p expression, and its overexpression decreased AKT, IGF-IR and IR protein expression. Furthermore, let-7d-5p hindered AKT phosphorylation in vitro after insulin stimulation. Finally, circulating let-7d-5p significantly decreased in steatosis patients and receiver operating characteristic (ROC) analyses confirmed its utility as a diagnostic biomarker. ; [Conclusions]: Our results highlight the emerging role of let-7d-5p as a potential therapeutic target for NAFLD since its overexpression impairs hepatic insulin signalling, and also, as a novel non-invasive biomarker for NAFLD diagnosis. ; This work was supported by grants RTI-2018-095098-B100 and PID2021-123076OB-I00 from the Ministerio de Ciencia, Innovación y Universidades, AENC1/22-29754 from UCM and PR75/18-21572 from Santander-UCM given to AG-H ...
