We next performed blood biochemistry to analyse the serum lipid levels. Serum cholesterol (total) levels had been substantially reduced (Fig. 4c) and NEFAshowed a non-significant lower in Acat2-overexpressing mice (Fig. 4d). These information indicate that Acat2 overexpression improves glucose tolerance and decreases serum cholesterol levels in mice.-Log10 (p value)Diabetologia (2023) 66:390Hepatic Acat2 overexpression inhibits lipid metabolism but promotes the anxiety response pathway We further confirmed regardless of whether liver and cardiac function have been impacted by Acat2 overexpression. Similar for the GTT outcome, serum glucose levels were not changed in Acat2-overexpressing mice compared with control-virus-injected mice (ESM Fig. 2a). Lactate dehydrogenase level was enhanced within the serum from Acat2-overexpressing mice (ESM Fig. 2b). The degree of aspartate aminotransferase (AST) in the serum of Acat2-overexpressing mice was elevated compared with that in the manage group but levels of alanine aminotransferase (ALT) and alkaline phosphatase (ALP) have been not changed (ESM Fig.VEGF121 Protein manufacturer 2c). TP (total protein) and ALB (albumin) levels have been slightly reduced following AAV9-Acat2 injection (ESM Fig. 2d). Heart rate and heart rate variability were not changed by Acat2 overexpression, as revealed by ECG (ESM Fig. 3a,b). Cardiac ultrasonography showed that Acat2 overexpression increased the left ventricular internal diameter (LVID) at endsystole but had no impact around the LVID at end-diastole, left ventricular posterior wall (LVPW) at end-diastole, LVPW at end-systole or the total cardiac output (ESM Fig.PMID:23551549 3c,d). These results collectively reveal that hepatic Acat2 overexpression has minor side-effects on the liver and cardiac function on the mice. We then isolated liver from mice injected with AAV9-Acat2 or control virus. FLAG and GFP western blotting revealed that ACAT2 protein was effectively overexpressed at both three weeks and three months following AAV9-Acat2 injection (Fig. 5a,b). Acat2 overexpression did not affect liver weight (Fig. 5c). H E staining and lipid quantification each showed that there was significantly less lipid, in particular triglyceride (TG), accumulation inside the liver immediately after Acat2 overexpression (Fig. 5d and ESM Fig. 4a). In addition, there was no difference inside the content of cholesterol and cholesteryl ester when comparing the two mouse groups (ESM Fig. 4b,c). Highthroughput RNA-sequencing was performed to learn differentially expressed genes (DEGs) in the liver of Acat2-overexpressing and manage mice. Soon after.
