In this study, integrated spatially resolved metabolomics and proteomics combined with mass spectrometry imaging(MSI) revealed a multi-scale region profile of the diabetic kidney. Based on anatomic location, spatial metabolomics revealed eight region-specific metabolite biomarkers uniquely localized to kidney segments, which were closely correlated to the clinical parameters of patients with DN. Specifically, treatment with metformin(MET) enriched inosinic acid, adenosine 3′,5′-diphosphate, nicotinamide adenine dinucleotide(NADH), and hydrated NADH(NADHX) levels in the cortex(Cor) and the outer stripe of kidney medulla(OM) anatomical subregions, while in the inner stripe of kidney medulla(IM) segmentation, the p-cresol sulfate level was downregulated. Comparing differently expressed proteins in each region showed that nephrosis 2(Nphs2) was the highest loading feature. A further region-specific analysis of pathway enrichment characteristics indicated that the purine and ether lipid metabolism pathways were enriched in the Cor and OM regions, whereas the pantothenate and coenzyme A(CoA) biosynthesis pathways were mainly enriched in the IM region in response to MET treatment. Taken together, the spatially segregated metabolomics and proteomics studies reveal MET-mediated proteins and function-specific therapeutic pathways related to the anatomical multiregion of diabetic mouse kidneys.展开更多
