Abstract:
:The aim of the work was to study the influence of vaspin on oxidative stress-induced apoptosis of mouse mesenchymal stem cells (MSCs). MSCs originated from bone marrow of C57BL/6 mouse were treated with vaspin and/or H2O2 in a dose-dependent manner. Cellular viability detected by CCK-8 and cell apoptosis studied by flow cytometry and TUNEL assay were observed in these cells. The protein expressions of PI3K, p-PI3K, Akt, p-Akt, T-ERK1/2, p-ERK1/2, p38, p-p38, JNK, and p-JNK were tested by Western blot. Vaspin had no significant effect on cellular viability, but significantly reduced H2O2-induced apoptosis. Western blot assay showed that pretreatment with vaspin promoted the activation of p-p38. Inhibition of p38 by SB203580 suppressed the protective effect of vaspin on oxidative stress-induced apoptosis. Vaspin inhibits oxidative stress-induced apoptosis of MSCs via the activation of MAPK/p38 signaling pathway. These findings indicate that vaspin is prone to osteoporosis protection.
