Summary: | Introduction:
Hypertensive disorders are of interest in obstetrics and gynecology because they are the second place among causes of maternal mortality and a source of complications in the short, mid, and long term. Even if the pathophysiological process behind preeclampsia (PE) is still unknown, stress factors have been revealed to play an important role in the genesis of this pathologic process.
Methods:
A case-control study was designed with the purpose of determining if there is a differential methylation in
NR3C1, HSD11B2, CYP11A1, CRHBP, TEAD3
, and
HSP90AA1
genes, related to signaling of the hypothalamic–pituitary–adrenal axis, and its regulation on early-onset PE (EOPE).
Results:
A total of 20 cases and 20 controls were studied by DNA methylation analysis, demonstrating differences among groups in the percentage of methylation of the
NR3C1
gene. After a contingency analysis, an odds ratio (OR) for PE of 12.25 was identified for
NR3C1
and 9.9 for
HSP90AA1
genes
. NR3C1, TEAD3
, and
HSP90AA1
genes showed a positive correlation with the systolic and diastolic blood pressure levels with a
p
≤ 0.05.
Conclusion:
This study found a differential methylation in the glucocorticoid receptor (GR)
NR3C1
and its co-chaperone
HSP90AA1
in women with PE, with a possible regulatory role in the response to stress in pregnancy and is a likely physiopathological mechanism in PE. |
