Title	Diabetes disturbs protein secretome of human adipose-derived stem cells and promotes tumorogenesis in hepatic cancer cells
Description	Metabolic disorders impact adipose-derived stem cells (ASCs), which play a central role in adipose tissue (AT) homeostasis but might also regulate tumour microenvironments via paracrine signalling routes. Here, we aimed to determine whether type 2 diabetes (T2D) disturbs the protein secretome of human ASCs, and its potential relevance for their pro-tumoral activity. An untargeted proteomics approach by liquid chromatography coupled to tandem mass spectrometry was used to analyse the secretome of ASCs isolated from the subcutaneous AT of subjects with and without T2D. Out of 231 quantified proteins, 52 factors were found differentially secreted on T2D-ASCs. In silico studies revealed that only 46,7% of the total proteins identified used the conventional secretory pathway. Network analysis showed up-secreted factors in T2D were implicated in immune system processes, extracellular matrix organization and endoplasmic reticulum stress. We found that diabetic ASCs secretome increases some inflammatory-, invasiveness- and epithelial-to-mesenchymal transition-related markers in HepG2 cells, an effect that was blocked with an anti-SUB1 antibody. Remarkably, SUB1 neutralization also inhibited invasive capacities of HepG2 in response to T2D-ASCs secretome. Overall, our study demonstrates that T2D-ASCs show an aberrant protein secretome and although further studies will be needed to understand the pathogenic consequences of this disturbance, our findings suggest that SUB1 might serve as a novel molecular link in the interplay between ASCs and tumor cells.
