Objective: To investigate damaging effects of clomifene citrate (CC) on endometrial stromal cells (hEndoSCs), and to study effects of spermidine on autophagy and inflammatory cytokine expression in damaged endometrial stromal cells. Methods: Groups were firstly divided into control group, spermidine group, clomiphene group (CC group), CC+Spermidine group. MTT assay was used to detect cell survival rate of hEndoSCs after co-incubation with different concentrations of CC or Spermidine for 24 h. Content of intracellular reactive oxygen species (ROS) and level of apoptosis in cells of the 4 groups were detected by flow cytometry technique. Western blot was used to detect expressions of autophagy pathway-related proteins ULK1, p-ULK1, LC-3 H, and apoptosis-related proteins Bax, Bcl-2, Cleaved-caspase 3. RT-qPCR was used to detect mRNA expressions of IL-6, IL-1β and TNF-α. Results: Compared with control group, CC group showed decreased cell survival, increased apoptosis rate, ROS content, Bax, Cleaved-caspase 3 expressions, decreased Bcl-2 expression, decreased levels of autophagy-related proteins p-ULK1 and LC-3 II/I, and elevated expressions of inflammatory factors IL-6, IL-1β and TNF-α mRNA (P<0.01). There was no significant changes viability of cells in spermidine group compared with control group (P>0.05). Compared with CC group, cell survival rate in CC+spermidine group was significantly increased, apoptosis rate, ROS content, Bax and Cleaved-caspase 3 expressions were decreased, Bcl-2 expression was increased, expressions of autophagy-related proteins p-ULK1 and LC-3 H/I were elevated, while expressions of inflammatory factors IL-6, IL-1β and TNF-α mRNA were decreased (P<0.01). Conclusion: CC can inhibit endometrial stromal cell proliferation, promote apoptosis, and increase the transcript levels of inflammatory factors IL-6, IL-1β and TNF-α. Spermidine can reduce intracellular ROS in clomiphene-injured endometrial stromal cells by activating cellular autophagy, increase cell survival, and inhibit the expressions of inflammatory factors IL-6, IL-1β and TNF-α.
