Relative gene expression of monocyte chemotactic protein 1 (MCP-1), interleukin 6 (IL-6), and IL-8 was evaluated with quantitative polymerase chain reaction and compared between treated and untreated cells with Wilcoxon matched pairs. The concentrations of MCP-1, IL-6, and IL-8 were measured using enzyme-linked immunosorbent assay and were compared between treated and untreated cells with Wilcoxon matched pairs.\nResults\nThe gene expression and protein secretion of IL-8 in endometriotic stromal cells after incubation with lignocaine 0.1 mg/mL were significantly decreased after 24 hours compared to the controls (P =.028 and P =.018). Macrophages from healthy controls had a significant lower gene expression of all tested cytokines (P =.043) after treatment with lignocaine, but there were no significant differences in protein level. Macrophages from women with endometriosis showed diverging results since 3 of 5 samples showed increased gene expression of 1 (n = 2) or 2 cytokines (n = 1) after lignocaine treatment.\nConclusion\nLignocaine can affect the gene expression and secretion of some proinflammatory cytokines in vitro.\nSimilar content being viewed by others\nReferences\nGiudice LC, Kao LC.
