ABSTRACT
OBJECTIVE:
This study aimed to investigate the roles of nuclear factor-kappa B p65 (NF-[Formula see text]B p65) and tumor necrosis factor-α (TNF-α) in cell apoptosis occurring in the fetal membranes of pregnant women who experience preterm premature rupture of membranes (PPROM).METHODS:
This was a case-control study involving 57 pregnant women who delivered in the obstetric department of Affiliated Loudi Hospital, Hengyang Medical School, University of South China, from June 2021 to June 2022. Samples of fetal membrane tissue were collected from pregnant women with PPROM (n=27) and pregnant women who had normal deliveries (control group; n=30). The membrane tissue morphology of both groups was observed, and the expression of NF-[Formula see text]B p65, p-NF-[Formula see text]B p65, TNF-α, and caspase-3 was detected. Apoptosis in fetal membranes was examined.RESULTS:
Morphological evaluation of the fetal membrane tissues obtained from patients with PPROM revealed an abnormal structure with a thin collagen fiber layer and cells with a largely vacuolar cytoplasm. There was a positive correlation between the expression of p-NF-[Formula see text]B p65/NF-[Formula see text]B p65 and cell apoptosis (r1 =0.89, R2 =0.805, P=0.00). Furthermore, TNF-α was positively correlated with fetal membrane cell apoptosis (r2 =0.93, R2=0.881, P=0.00).CONCLUSION:
NF-[Formula see text]B p65 is involved in the occurrence of PPROM by promoting the expression of TNF-α, which upregulates caspase-3 to cause apoptosis of fetal membrane cells.Palabras clave
