Abstract
- Background: Low temperature plasma (LTP) exerts a protective effect in inflammation via enhancing MANF expression. Hyperactivation and dysfunction of theca cells induced by inflammatory agents is accompanied by polycystic ovary syndrome (PCOS), which is a common reproductive and endocrine disorder. However, the effect of LTP on theca cells is still unknown. Methods and results: Theca cells were stimulated with IL-1β or TNF-α for 12 h, then treated with LTP for 100 s. After 8 h, medium supernatant and theca cells were collected. Production of androgen from theca cells were detected by ELISA. The PCNA and Annexin V levels in theca cells were detected by using immunofluorescent staining. The levels of PCNA, BCL-2 and BAX were evaluated by western blot and qPCR. MTT assay was used to detect the viability of theca cells. The proportions of apoptosis of theca cells were detected by Flow cytometry. The mRNA levels of androgenic genes were detected by qPCR. The MANF levels in medium supernatant and cell lysate were detected by using ELISA, western and qPCR. BIP and CHOP expressions were detected by using western blot and qPCR. We found that LTP irradiation decreased inflammatory agents-induced upregulation of androgen and androgenic genes in theca cells. And LTP irradiation relieves IL-1β or TNF-α-induced pathological proliferation and apoptosis in theca cells. In terms of mechanism, LTP irradiation increased MANF level in theca cells to inhibit BIP and CHOP expression. Conclusion: These evidences suggest the protective effect of LTP on theca cells in inflammatory microenvironment, and LTP has the potential clinical application of PCOS. [ABSTRACT FROM AUTHOR]
