Zhang W, Wang H, Deng C. Hypoxia-induced upregulation of hsa-miR-584-3p suppresses endometrial glandular epithelial cell function by targeting DKK-1. Am J Transl Res 2024; 16:2001-2010. [PMID: 38883346 PMCID: PMC11170570 DOI: 10.62347/pfcf4169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/15/2024] [Accepted: 05/11/2024] [Indexed: 06/18/2024]
Abstract
OBJECTIVE To investigate the impact of hypoxia on microRNA (miRNA) expression profiles in endometrial glandular epithelial cells (EECs) and elucidate potential mechanisms underlying proliferation, migration, and invasion. METHODS EECs in the logarithmic growth phase were exposed to normoxic (21% oxygen) and hypoxic (1% oxygen) conditions. MiRNA expression profiles were analyzed using RNA sequencing, and differential expression of hsa-miR-584-3p was confirmed by real-time quantitative PCR (RT-qPCR). Target prediction through TargetScan identified Dickkopf-1 (DKK-1) as a target gene of hsa-miR-584-3p. The interaction between hsa-miR-584-3p and DKK-1 was validated through a double-luciferase reporter gene assay and Western blotting. Cell proliferation, migration, and invasion were assessed using the Cell Counting Kit-8 (CCK-8) assay, wound healing assay, and Transwell invasion assay, respectively. RESULTS Hypoxic conditions significantly upregulated the expression of hsa-miR-584-3p in EECs (P<0.001). TargetScan analysis predicted DKK-1 as a downstream target of hsa-miR-584-3p. The double-luciferase reporter gene assay confirmed the binding of hsa-miR-584-3p to the 3' untranslated region of the DKK-1 gene, leading to reduced DKK-1 protein expression (P<0.001). Functional assays demonstrated decreased proliferation and increased migration and invasion of EECs under hypoxia. CONCLUSION Hypoxia-induced upregulation of hsa-miR-584-3p suppresses the function of EECs by targeting DKK-1 protein activity, thereby influencing their proliferation, migration, and invasion.

J Cell Physiol 2024; 239:166-179. [PMID: 37991438 DOI: 10.1002/jcp.31153] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2023] [Revised: 10/11/2023] [Accepted: 10/26/2023] [Indexed: 11/23/2023]
Abstract
Abnormal function and fibrosis of endometrium caused by cows' endometritis pose difficult implantation of embryos and uterine cavity adhesions. 17β-Estradiol (E2) serves as the most effective aromatized estrogen, and its synthetase and receptors have been detected in the endometrium. Studies have demonstrated the positive role of estrogen in combating pathological fibrosis in diverse diseases. However, it is still unknown whether E2 regulates endometrium fibrosis in bovine endometritis. Herein, we evaluated the expression patterns of transforming growth factor-β1 (TGF-β1), epithelial-mesenchymal transformation (EMT)-related proteins (α-SMA, vimentin N-cadherin and E-cadherin), cytochrome P450 19A1 (CYP19A1), and G protein-coupled estrogen receptor (GPER) in bovine healthy endometrium and Inflammatory endometrium. Our data showed that the inflamed endometrium presented low CYP19A1 and GPER expression, and significantly higher EMT process versus the normal tissue. Moreover, we established a TGF-β1-induced fibrosis model in BEND cells, and found that E2 inhibited the EMT process of BEND cells in a dose-dependent manner. The anti-fibrotic effect of E2 was blocked by the GPER inhibitor G15, but not the estrogen nuclear receptors (ERs) inhibitor ICI182780. Moreover, the GPER agonist G1 inhibited fibrosis and Smad2/3 phosphorylation but increased the expression of TGFBR3 in BEND cells. Transfection with TGFBR3 small interfering RNA blocked the effect of G1 on fibrosis of BEND cells and upregulated the expression of P-Smad2/3. Our in vivo data also showed that E2 and G1 affected uterus fibrosis in mice endometritis model caused by LPS, which was associated with the inhibition of TGFBR3/Smad2/3 signaling. In conclusion, our data implied that E2 alleviates the fibrosis of TGF-β1-induced BEND cells, which is associated with the GPER mediation of TGFBR3/Smad2/3 signaling.

[PMID: 37648092 DOI: 10.1016/j.brainres.2023.148560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2023] [Revised: 08/17/2023] [Accepted: 08/27/2023] [Indexed: 09/01/2023]
Abstract
White matter injury is the most common form of brain injury in preterm infants. In addition to hypoxia ischemia, intrauterine infection is most closely related to brain white matter injury. Our study aimed to explore the mechanism of the miR-199a-5p/HIF-1α axis on astrocyte activation and brain injury in newborn rats caused by intrauterine infection. The animal/cell model was established via escherichia coli infection/lipopolysaccharide induction, followed by the measurement of body weight, brain weight, and the pathological changes in brain tissues of newborn rats, and the pathological changes in placenta and uterus wall of pregnant rats. Also, the levels of GFAP, TNF-α, MDA, GSH, SOD, miR-199a-5p, and HIF-1α were detected though corresponding assays or kits. In vitro, cell viability and apoptosis and the levels of IL-6 and TNF-α were evaluated in astrocytes. Moreover, the targeting relationship between miR-199a-5p and HIF-1α was verified. miR-199a-5p was lowly expressed in the brain tissues of newborn rats with intrauterine infection. Overexpression of miR-199a-5p relieved the injury of placenta and uterus wall in pregnant rats and brain injury in newborn rats, accompanied by decreased HIF-1α, GFAP, TNF-α, and MDA levels and increased GSH and SOD levels. Results from cell models showed that miR-199a-5p overexpression inhibited astrocyte activation, shown by enhanced cell viability, weakened cell apoptosis, and decreased GFAP, IL-6, and TNF-α. Mechanistically, miR-199a-5p targeted HIF-1α to decrease its expression. Collectively, miR-199a-5p inhibited astrocyte activation and alleviated brain injury in newborn rats with intrauterine infection by reducing HIF-1α expression.

COVID-19-The Shift of Homeostasis into Oncopathology or Chronic Fibrosis in Terms of Female Reproductive System Involvement. Int J Mol Sci 2023; 24:ijms24108579.

Abstract
The COVID-19 pandemic caused by the SARS-CoV-2 coronavirus remains a global public health concern due to the systemic nature of the infection and its long-term consequences, many of which remain to be elucidated. SARS-CoV-2 targets endothelial cells and blood vessels, altering the tissue microenvironment, its secretion, immune-cell subpopulations, the extracellular matrix, and the molecular composition and mechanical properties. The female reproductive system has high regenerative potential, but can accumulate damage, including due to SARS-CoV-2. COVID-19 is profibrotic and can change the tissue microenvironment toward an oncogenic niche. This makes COVID-19 and its consequences one of the potential regulators of a homeostasis shift toward oncopathology and fibrosis in the tissues of the female reproductive system. We are looking at SARS-CoV-2-induced changes at all levels in the female reproductive system.
