J Med Case Rep 2022; 16:191. [PMID: 35568885 PMCID: PMC9107689 DOI: 10.1186/s13256-022-03421-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2021] [Accepted: 04/22/2022] [Indexed: 11/29/2022] Open
Abstract
Background Ocular vascular occlusion is an extremely rare event, especially in the young population. This diagnosis is always associated with active systemic diseases in young adults and needs thrombophilia workup. Nevertheless, we present the case of a pregnant woman suffering from idiopathic combined central retinal vein and cilioretinal artery occlusion. Case presentation A 36-year-old pregnant Iranian woman at the 36th week of her second pregnancy complained of subacute unilateral painless decreased vision of her left eye. She had experienced a transient vision loss that lasted several minutes, but attacks gradually became more frequent and finally persistent over a several-day period. Finally combined central retinal vein and cilioretinal artery occlusion was established. Her visual acuity improved to 4/10 in a month without any ocular intervention except for a short duration of prophylactic dose enoxaparin, and the acuity reached 8/10 without any complications in the third month follow-up visit. At 1 year follow-up, the visual acuity had not changed and no macular edema was seen. Conclusions Ocular vascular occlusion is extremely rare among young adults, and even rarer among pregnant women. According to this, any suspected retinal vascular event in this population should raise suspicion for underlying diseases such as hypertension, diabetes, autoimmune diseases, migraine, preeclampsia syndrome, and thrombophilia. However, as seen in this presented case, idiopathic ocular vascular occlusion events can occur also.

Abstract
Globally, pre-eclampsia (PE) is a gestational disorder that causes increased morbidity of the fetus and mortality induced by pregnancy. Despite various studies, the understanding of the causes or mechanism of the development of PE remains elusive. Thus, the present study aimed to investigate the role of circular (circ)RNA hsa_circ_0026552 (hsa_circ_0026552) in the development of PE and its mechanism of regulation. hsa_circ_0026552 differential expression in PE tissue data and clinical samples were analyzed and it was observed that hsa_circ_0026552 is highly upregulated in PE samples. Furthermore, miR-331-3p was detected as an hsa_circ_0026552 target miRNA and TGF-βR1 gene as a target of miR-331-3p. These results were confirmed using various assays, including dual-luciferase reporter, reverse transcription-quantitative PCR and RNA pull-down assay. It was observed that miR-331-3p expression was negatively correlated to hsa_circ_0026552 relative expression, while TGF-βR1 expression was positively correlated to hsa_circ_0026552 expression evaluated by Pearson's correlation test. The functional experiments, including Cell Counting Kit-8, colony formation and Transwell assay, showed that silencing hsa_circ_0026552 could significantly strengthen the proliferation, migration and invasion of the trophoblastic HTR-8/SVneo cells, but the subsequent overexpression of hsa_circ_0026552 reversed this. Mechanistically, it was concluded that hsa_circ_0026552 acts as a miR-331-3p sponge to upregulate TGF-βR1 expression in trophoblasts and is involved significantly in PE development and progression in pregnant women. The circRNA hsa_circ_0026552 could be a novel therapeutic target and prognostic biomarker for PE.

Abstract
Pregnancy is a condition often characterized by changes that occur in different parts of the body. Generally, the eyes suffer several changes during pregnancy that are usually transient but may become permanent at times. This may occur due to the release of placental hormones and those of maternal endocrine glands and fetal adrenal glands. Due to hormonal influences, physiological ocular changes during pregnancy have been shown in Caucasian women, so corneal sensitivity, refractive status, intraocular pressure, and visual acuity may change during pregnancy. Within this review, all studies that referred to physiological aspects and to changes of ocular pathology of pregnancy, the effect of the pregnancy on pre-existing (diabetic retinopathy, neuro-ophthalmic disorders) eye disorders, postpartum ocular changes, the intraocular pressure and the effect of hypotensive ophthalmic medicine during pregnancy, the connection between pregnancy and the neuro-ophthalmic pathology, as well as the role of anesthesia were analyzed.

Abstract
Long noncoding RNAs (lncRNAs) are crucial regulatory molecules involved in diverse biological processes and human diseases, including preeclampsia (PE). The lncRNA growth arrest associated lncRNA 1 (GASAL1) has been implicated in multiple malignant solid tumors and other diseases, while it is poorly known as the potential molecular mechanism of GASAL1 in PE. In this study, GASAL1 was significantly downregulated in the placentas' of tissues from primipara with PE and trophoblast cell lines. Then, the upregulation of GASAL1 dramatically decreased proliferation and invasion and enhanced apoptosis in HTR-8/SVneo and JAR cells. Bioinformatics tool predicated that there is a potential interaction between GASAL1 and serine/arginine splicing factor 1 (SRSF1). RNA pull-down assays showed that GASAL1 directly binds with SRSF1 that could promote cell proliferation and invasion and suppress cell apoptosis. Further research showed that promoting effects of trophoblasts proliferation and invasion caused by co-transfecting GASAL1 and SRSF1 into HTR-8/SVneo and JAR cells were impaired by SRSF1 knockdown. Moreover, inhibition of the mammalian target of rapamycin (mTOR) activity by rapamycin influenced the effects of GASAL1 on cell proliferation, invasion, and apoptosis. Taken together, these findings suggest that lncRNA GASAL1 interacts with SRSF1 to regulate the proliferative, invasive, and apoptotic abilities of trophoblast cells via the mTOR signaling pathway.

Abstract
Preeclampsia (PE) is a pregnancy-specific syndrome and contributes to maternal and perinatal morbidity and mortality, but the underlying mechanisms of PE remain indistinct. This study aims to investigate the functional role of LncRNA CRNDE in PE pathogenesis and its effects on trophoblasts. mRNA levels of CRNDE and miR-1277 in placenta tissues and HTR-8/SVneo cells were analyzed by qRT-PCR. Western blot was carried out to evaluate protein level of E-cadherin, β-Catenin, Vimentin, MMP2 and MMP9. Cell proliferation was assessed by using CCK-8 assay and colony formation assay, whereas cell migration and invasion were evaluated by wound healing assay and transwell assay, respectively. Moreover, the interrelation between CRNDE and miR-1277 was verified by dual luciferase reporter assay. The results showed that CRNDE expression was significantly downregulated, whereas miR-1277 expression was significantly upregulated in PE placental tissues. Overexpression of CRNDE facilitated HTR-8/SVneo cell proliferation, migration and invasion, promoted the EMT formation, and increased the protein expression of MMP2 and MMP9, while knockdown of CRNDE had the opposite results. In addition, we also found that miR-1277 was negatively regulated by CRNDE and was a direct target of CRNDE. Furthermore, knockdown of miR-217 promoted HTR-8/SVneo cell proliferation, migration, and invasion, while knockdown of CRNDE reversed the accelerating effects of miR-1277 on HTR-8/SVneo cells. LncRNA CRNDE may suppress trophoblast cell proliferation, migration and invasion at least partly through regulating miR-1277 in trophoblast cells. CRNDE is promising to function as a new target for intervention of PE.

Abstract
OBJECTIVES Despite improvements in diagnosis and treatment, preeclampsia (PE) continues to pose a significant risk of maternal and foetal morbidity and mortality if not addressed promptly. An increasing number of studies have suggested that tissue factor pathway inhibitor 2 (TFPI2) acts as a suppressor gene, possibly inhibiting multiple serine proteases affecting cell proliferation and migration. It plays an essential role in the occurrence and development of PE, but the pathogenesis remains unclear. MATERIALS AND METHODS In our research, we performed western blotting, immunohistochemistry and qPCR assays to investigate TFPI2 and miR-616-3p expression in preeclamptic placental tissues. Cell assays were performed in HTR-8/SVneo and JEG3 cell lines. Cell proliferation and migration events were investigated by MTT, EdU and transwell assays. In conjunction with bioinformatics analysis, luciferase reporter assays were performed to elucidate the mechanism by which miR-616-3p binds to TFPI2 mRNA. RESULTS We established that TFPI2 protein levels were significantly upregulated in PE placental tissues. In addition, we found that miR-616-3p binds specifically to the 3'-UTR region of TFPI2 mRNA. Furthermore, miR-616-3p knockdown or TFPI2 overexpression substantially impaired cell growth and migration, whereas miR-616-3p upregulation or TFPI2 knockdown stimulated cell proliferation and migration. This miR-616-3p/TFPI2 axis was also found to affect the epithelial-mesenchymal transition process in PE. CONCLUSIONS Our results demonstrated that TFPI2 plays a vital role in the progression of PE and might provide a prospective therapeutic strategy to mitigate the severity of the disorder.

Abstract
Preeclampsia (PE), a pregnancy‐specific disorder, is associated with impaired uterine spiral artery remodelling, which is related to the dysfunction of trophoblast cells. Lately, mounting evidence has indicated that aberrant expression of long non‐coding RNAs (lncRNAs) is associated with various human diseases. The lncRNA MVIH transcript has been shown to decrease the severity of several diseases. However, the biological function of MVIH, which is down‐regulated in placental tissues in PE, has not yet been clarified. Here, we report that MVIH may act as a vital factor in the pathogenesis of PE. In this study, functional analysis revealed that the silencing of MVIH expression via transfection with small interfering RNA (siRNAs) inhibited cell growth, migration, invasion, and angiogenesis in various trophoblast cell lines, and stimulation with MVIH could promote these functions. Mass spectrometry analysis revealed that MVIH could modulate Jun‐B protein expression, which has been reported to potentially regulate cell growth and angiogenesis. Further cotransfection assays were performed, revealing that MVIH and Jun‐B have a synergistic effect on the regulation of angiogenesis and cell proliferation. Taking these findings together, MVIH could be associated with PE and may be a candidate biomarker for its diagnosis and treatment.

Abstract
Due to limited treatment options, pre-eclampsia (PE) is associated with fetal perinatal and maternal morbidity and mortality. During the causes of PE, failure of uterine spiral artery remodeling which might be related to functioning abnormally of trophoblast cells, result in the occurrence and progression of PE. Recently, abnormal expression of long non-coding RNAs (lncRNAs), as imperative regulators involved in human diseases progression (included PE), which has been indicated by increasing evidence. In this research, we found that TUG1, a lncRNA, was markedly reduced in placental samples from patients with PE. Loss-function assays indicated that knockdown TUG1 significantly affected cell proliferation, apoptosis, migration and network formation in vitro. RNA-seq revealed that TUG1 could affect abundant genes, and then explore the function and regulatory mechanism of TUG1 in trophoblast cells. Furthermore, RNA immunoprecipitation and chromatin immunoprecipitation assays validated that TUG1 can epigenetically inhibit the level of RND3 through binding to EZH2, thus promoting PE development. Therefore, via illuminating the TUG1 mechanisms underlying PE development and progression, our findings might furnish a prospective therapeutic strategy for PE intervention.

Abstract
Preeclampsia is a common, pregnancy-specific disease and a major contributor to maternal and foetal morbidity and mortality. Some placental abnormalities, including deficient implantation, abnormal trophoblast cell function, and improper placental vascular development, are believed to lead to preeclampsia. The long noncoding RNA SPRY4-IT1 is more highly expressed in preeclamptic human placentas than in normal placentas. We assessed the role of epithelial-mesenchymal transition (EMT)-associated invasion and migration in HTR-8/SVneo trophoblast cells. Overexpression of SPRY4-IT1 suppressed trophoblast cell migration and invasion, whereas reduced expression of SPRY4-IT1 prevented the EMT process. Mechanistically, an RNA immunoprecipitation experiment showed that SPRY4-IT1 bound directly to HuR and mediated the β-catenin expression associated with EMT in HTR-8/SVneo cells. Moreover, the expression levels of genes in the WNT family, such as WNT3 and WNT5B, were changed after transfection of HTR-8/SVneo with SPRY4-IT1. Together, our results highlight the roles of SPRY4-IT1 in causing trophoblast cell dysfunction by acting through the Wnt/β-catenin pathway, and consequently in impairing spiral artery remodelling. These results suggest a new potential therapeutic target for intervention against preeclampsia.
