| description | Abstract Objectives Equine metabolic syndrome (EMS) refers to a cluster of associated abnormalities and metabolic disorders, including insulin resistance and adiposity. The numerous biological properties of mesenchymal stem cells (MSCs), including self-renewal and multipotency, have been the subject of many in-depth studies, for the management of EMS; however, it has been shown that this cell type may be affected by the condition, impairing thus seriously their therapeutic potential. Therefore, an attempt to rescue EMS adipose-derived stem cells (ASCs) with calystegines (polyhydroxylated alkaloids) that are endowed with strong antioxidant and antidiabetic abilities was performed. Methods ASCs isolated from EMS horses were subsequently treated with various concentrations of total calystegines. Different parameters were then assessed using flow cytometry, confocal as well as SE microscopy, and RT-qPCR. Results Our results clearly demonstrated that calystegines could improve EqASC viability and proliferation and significantly reduce apoptosis, via improvement of mitochondrial potentiation and functionality, regulation of pro- and anti-apoptotic pathways, and suppression of ER stress. Furthermore, nortropanes positively upregulated GLUT4 and IRS transcripts, indicating a possible sensitizing or mimetic effect to insulin. Most interesting finding in this investigation lies in the modulatory effect of autophagy, a process that allows the maintenance of cellular homeostasis; calystegines acted as pharmacological chaperones to promote cell survival. Conclusion Obtained data open new perspectives in the development of new drugs, which may improve the metabolic dynamics of cells challenged by MS. |
