Ingenuity pathway analysis of gingival epithelial cells stimulated with estradiol and progesterone. | LitMetric
Objective : Periodontal disease is a risk factor for preterm delivery, and elevated female hormone levels during pregnancy promote hormone-dependent periodontopathogenic bacterial growth and gingivitis. Although the saliva of pregnant women contains female hormones at elevated levels, their effects on the gingiva are poorly understood. Therefore, in this study, we investigated the effects of estradiol and progesterone stimulation on gingival epithelial cells via ingenuity pathway analysis.Methods : Human gingival epithelial progenitors were cultured in a CnT-Prime medium; 17β-estradiol (E2) and progesterone (P4) were used as the reagents. Cells treated with dimethyl sulfoxide alone were used as the control group. Cells in the control and experimental groups were incubated for 12 h. RNA was extracted from the cultured cells, RNA-Seq was performed, and pathway analysis was conducted.Results : Differentially expressed genes were detected for 699 (over 2-fold increase) and 348 (decrease) genes in group E2 and for 1448 (increase) and 924 (decrease) genes in group P4 compared with those in the control group (FDR <0.05, n = 4). The z-scores of the pathways suggest that E2 and P4 increased the activity of the wound healing signaling pathway. The activation of this pathway was higher in the E2 and P4 groups than that in the control group.Conclusions : The results of this study suggest that estradiol and progesterone may affect gingival homeostasis and wound healing.
