Polygonum cuspidatum glycoside mitigated LPS-induced human endometrial stromal cell inflammation by regulating NF-κB/Nrf2 signaling pathway-related proteins
Abstract
Purpose: To study the influence of polydatin on LPS-provoked human endometrial stromal cell inflammation, and its mechanism of action.
Methods: Fifty ICR female mice were selected and assigned to control and three-dose polydatin groups. Before establishment of the model, mice in low-dose group, middle-dose group and high-dose group were given polydatin at doses of 5, 10 and 20 mg/kg, respectively, by oral gavage for 5 days. Protein expression levels of interleukin 1β (IL-1 β), tumor necrosis factor- α (TNF-α) level, nuclear factor E2-related factor 2 (NRF-2) and nuclear transcription factor kappa-B (NF-2 κB) were determined with Western blot assay.
Results: Model group mice protein levels of NF- κB and nrf-2 were significantly reduced, relative to the corresponding control values (p < 0.05). The NF-κB and NRF-2 proteins in model group were markedly up-regulated, relative to control group, but they were and dose-dependently lower in the 3 polydatin groups than in control (p < 0.05). Conclusion: Polydatin reduces LPS-induced inflammatory response in mouse endometrial stromal cells, and promotes the repair of endometrium and regeneration of glands via a mechanism related to regulation of NF-κ B/Nrf2 signaling pathway-related proteins.
