Abstract
OBJECTIVE Preeclampsia (PE) is a pregnancy-specific condition featured by high blood pressure, edema, and proteinuria. Research about the role of microRNA (miR)-203 in PE remains insufficient. This experiment is designed to investigate the specific role of miR-203 in trophoblasts in PE. STUDY DESIGN miR-203 expression in placenta tissues of normal pregnant women and PE patients was examined to analyze the relevance between miR-203 and PE diagnostic efficiency and between miR-203 and blood pressure (systolic pressure and diastolic pressure) and proteinuria of PE patients. miR-203 expression was downregulated in hypoxia-cultured trophoblasts using miR-203 inhibitor to assess matrix metalloproteinase-9 (MMP-9) level. Then, the angiogenesis of trophoblasts with different treatments was determined. Subsequently, the target relation between miR-203 and insulin-like growth factor receptor 1 (IGF-1R) was predicted and verified. Additionally, the effect of IGF-1R in the mechanism of miR-203 modulating trophoblast vascular remodeling was detected. RESULTS miR-203 was overexpressed in the placenta of PE patients and it acted as a promising diagnostic indicator for PE. Moreover, miR-203 was positively associated with blood pressure (systolic pressure and diastolic pressure) and proteinuria of PE patients. miR-203 silencing in hypoxia-cultured trophoblasts enhanced trophoblast vascular remodeling. Mechanically, miR-203 bound to IGF-1R to suppress its transcription. IGF-1R downregulation counteracted the promotive effect of miR-203 silencing on trophoblast vascular remodeling. CONCLUSION miR-203 was overexpressed in PE, and it targeted IGF-1R to limit trophoblast vascular remodeling. KEY POINTS · miR-203 is overexpressed in the placenta of PE patients.. · miR-203 acts as a potential diagnostic marker for PE.. · miR-203 targets IGF-1R to reduce trophoblast vascular remodeling in PE..

Multi-Omic Profiles in Infants at Risk for Food Reactions. Genes (Basel) 2022; 13:genes13112024.

Abstract
Food reactions (FR) are multifactorial and impacted by medical, demographic, environmental, and immunologic factors. We hypothesized that multi-omic analyses of host-microbial factors in saliva would enhance our understanding of FR development. This longitudinal cohort study included 164 infants followed from birth through two years. The infants were identified as FR (n = 34) or non-FR (n = 130) using the Infant Feeding Practice II survey and medical record confirmation. Saliva was collected at six months for the multi-omic assessment of cytokines, mRNAs, microRNAs, and the microbiome/virome. The levels of one miRNA (miR-203b-3p, adj. p = 0.043, V = 2913) and one viral phage (Proteus virus PM135, adj. p = 0.027, V = 2955) were lower among infants that developed FRs. The levels of one bacterial phylum (Cyanobacteria, adj. p = 0.048, V = 1515) were higher among infants that developed FR. Logistical regression models revealed that the addition of multi-omic features (miR-203b-3p, Cyanobacteria, and Proteus virus PM135) improved predictiveness for future FRs in infants (p = 0.005, X2 = 12.9), predicting FRs with 72% accuracy (AUC = 0.81, sensitivity = 72%, specificity = 72%). The multi-omic analysis of saliva may enhance the accurate identification of infants at risk of FRs and provide insights into the host/microbiome interactions that predispose certain infants to FRs.

J Steroid Biochem Mol Biol 2022; 222:106155.

Abstract
Vitamin D deficiency is a widespread health problem globally and vitamin D deficiency/ insufficiency in pregnancy is a risk factor for preeclampsia, a hypertensive disorder in human pregnancy. Vitamin D elicits its biological effects through binding to its receptor VDR. In the present study, we determined maternal vascular expression of VDR and hnRNPC1/C2, a native repressor of VDR, in subcutaneous adipose tissue from women with normal pregnancy and preeclampsia. Maternal antenatal and postnatal vitamin D levels were measured. We found that hnRNPC1/C2 expression was markedly increased, while VDR expression was markedly reduced, in maternal vessel endothelium and smooth muscle cells from women with preeclampsia compared to that from normal pregnant controls. Reduced VDR expression was relevant to low maternal antenatal and postnatal vitamin D levels in women with preeclampsia. Using human umbilical vein endothelial cells (HUVECs) as an endothelial model, we further investigated the role of hnRNPC1/C2-mediated VDR expression in endothelial cells, and tested effect of hnRNPC1/C2 inhibition on endothelial response to bioactive vitamin D, 1,25(OH)2D3. Our results showed that inhibition of hnRNPC1/C2 by hnRNPC1/C2 siRNA resulted in not only an increase in endothelial VDR expression, but further improved endothelial response to 1,25(OH)2D3. These findings indicate that aberrant hnRNPC1/C2 expression may contribute to reduced vascular expression of VDR in women with preeclampsia and suggest that hnRNPC1/C2 could be a target for improving vascular endothelial cell response to vitamin D.

Abstract
Introduction: Preeclampsia (PE) is a pregnancy-associated, multi-organ, life-threatening disease that appears after the 20th week of gestation. The aim of this study was to perform a systematic review and meta-analysis to determine whether women with PE have disrupted miRNA expression compared to women who do not have PE. Methods: We conducted a systematic review and meta-analysis of studies that reported miRNAs expression levels in placenta or peripheral blood of pregnant women with vs. without PE. Studies published before October 29, 2021 were identified through PubMed, EMBASE and Web of Science. Two reviewers used predefined forms and protocols to evaluate independently the eligibility of studies based on titles and abstracts and to perform full-text screening, data abstraction and quality assessment. Standardized mean difference (SMD) was used as a measure of effect size. Results: 229 publications were included in the systematic review and 53 in the meta-analysis. The expression levels in placenta were significantly higher in women with PE compared to women without PE for miRNA-16 (SMD = 1.51,95%CI = 0.55-2.46), miRNA-20b (SMD = 0.89, 95%CI = 0.33-1.45), miRNA-23a (SMD = 2.02, 95%CI = 1.25-2.78), miRNA-29b (SMD = 1.37, 95%CI = 0.36-2.37), miRNA-155 (SMD = 2.99, 95%CI = 0.83-5.14) and miRNA-210 (SMD = 1.63, 95%CI = 0.69-2.58), and significantly lower for miRNA-376c (SMD = -4.86, 95%CI = -9.51 to -0.20). An increased level of miRNK-155 expression was found in peripheral blood of women with PE (SMD = 2.06, 95%CI = 0.35-3.76), while the expression level of miRNA-16 was significantly lower in peripheral blood of PE women (SMD = -0.47, 95%CI = -0.91 to -0.03). The functional roles of the presented miRNAs include control of trophoblast proliferation, migration, invasion, apoptosis, differentiation, cellular metabolism and angiogenesis. Conclusion: miRNAs play an important role in the pathophysiology of PE. The identification of differentially expressed miRNAs in maternal blood creates an opportunity to define an easily accessible biomarker of PE.

Abstract
Preeclampsia is a complication of pregnancy characterized by high blood pressure and organ damage after 20 gestational weeks. It is associated with high maternal and fetal morbidity and mortality. However, at present, there is no effective prevention or treatment for this condition. Previous studies have revealed that plasma exosomal mirnas from pregnant women with preeclampsia could serve as biomarkers of pathogenic factors. However, the roles of plasma exosomal mirnas in preeclampsia with severe features (sPE), which is associated with poorer pregnancy outcomes, remain unknown. Thus, the aims of this study were to characterize plasma exosomal miRNAs in sPE and explore the related pathogenic mechanisms using bioinformatic analysis. Plasma exosomes were isolated using a mirVana RNA isolation kit. the exosomal miRNAs were detected using high-throughput sequencing and the mirnas related to Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways and gene ontology (GO) terms were analyzed using the clusterprofiler package of R. Fifteen miRNAs exhibited increased expression and fourteen miRNAs exhibited reduced expression in plasma exosomes from women with sPE as compared to normal pregnant women. Further, gene set enrichment analysis revealed that the differentially expressed plasma exosomal miRNAs were related to the stress response and cell junction regulation, among others. In summary, this study is the first to identify the differentially expressed plasma exosomal miRNAs in sPE. These findings highlight promising pathogenesis mechanisms underlying preeclampsia.

Abstract
Preeclampsia (PE) is an idiopathic disease that occurs during pregnancy. It comprises multiple organ and system damage, and can seriously threaten the safety of the mother and infant throughout the perinatal period. As the pathogenesis of PE is unclear, there are few specific remedies. Currently, the only way to eliminate the clinical symptoms is to terminate the pregnancy. Although noncoding RNA (ncRNA) was once thought to be the "junk" of gene transcription, it is now known to be widely involved in pathological and physiological processes, including pregnancy-related disorders. Moreover, there is growing evidence that the unbalanced expression of specific ncRNA is involved in the pathogenesis of PE. In the present review, we summarize the expression patterns of ncRNAs, i.e., microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs), and the functional mechanisms by which they affect the development of PE, and examine the clinical significance of ncRNAs as biomarkers for the diagnosis of PE. We also discuss the contributions made by genetic polymorphisms and epigenetic ncRNA regulation to PE. In the present review, we wish to explore and reinforce the clinical value of ncRNAs as noninvasive biomarkers of PE.

Abstract
Endothelial dysfunction is considered as the main hallmark of Preeclampsia (PE). Despite the unknown pathogenesis of PE, different possible causes have been suggested in various studies. In this review, we first studied the Leukemia inhibitory factor (LIF) role in the related pathways to the PE pathogenesis, such as inflammation, endothelial dysfunction and hypertension. LIF can increase the expression of ICAM-1 and VCAM-1 via the JAK/STAT3 pathway, thereby inducing inflammatory responses and endothelial dysfunction. It can also be involved in the vascular vasoconstriction and hypertension by reducing the nitric oxide (NO) synthesis. Identifying the link between LIF and pathways associated with PE pathogenesis could be effective to achieve an effective PE treatment in the future.

Abstract
Preeclampsia is a clinical syndrome characterized by multiple-organ dysfunction, such as maternal hypertension and proteinuria, after 20 weeks of gestation. It is a common cause of fetal growth restriction, fetal malformation, and maternal death. At present, termination of pregnancy is the only way to prevent the development of the disease. Non-coding RNAs, including microRNAs, long non-coding RNAs, and circular RNAs, are involved in important pathological and physiological functions in life cycle activities including ontogeny, reproduction, apoptosis, and cell reprogramming, and are closely associated with human diseases. Accumulating evidence suggests that non-coding RNAs are involved in the pathogenesis of preeclampsia through regulation of various physiological functions. In this review, we discuss the current evidence of the pathogenesis of preeclampsia, introduce the types and biological functions of non-coding RNA, and summarize the roles of non-coding RNA in the pathophysiological development of preeclampsia from the perspectives of oxidative stress, hypoxia, angiogenesis, decidualization, trophoblast invasion and proliferation, immune regulation, and inflammation. Finally, we briefly discuss the potential clinical application and future prospects of non-coding RNA as a biomarker for the diagnosis of preeclampsia.

MiR-141-3p downregulation promotes tube formation, migration, invasion and inhibits apoptosis in hypoxia-induced human umbilical vein endothelial cells by targeting Notch2.

Abstract
Vascular endothelial cell damage is regarded as the carrier in the progression of the pathological changes of preeclampsia (PE) from the placenta to maternal organs. MicroRNA (miR)-141-3p was aberrantly expressed during PE pathogenesis. We investigated the role of miR-141-3p in regulating the biological behaviors of endothelial cells in PE. Human umbilical vein endothelial cells (HUVECs) were isolated from the human umbilical cords and cultured under hypoxia condition to establish PE models. The binding of miR-141-3p and Notch2 was confirmed by dual-luciferase reporter assay. HUVECs were transfected with miR-141-3p inhibitor and siRNA-Notch2. The viability, vascularization capability, migration, and invasion of HUVECs were evaluated by MTT, tube formation, and Transwell assays. Cell apoptosis was measured via flow cytometry. The expressions of miR-141-3p, Notch2, Bcl-2, Bax and cleaved caspase-3 were assessed by qRT-PCR or Western blot. MiR-141-3p expression was upregulated in the HUVECs isolated from PE tissues and hypoxia-induced HUVECs. Hypoxia treatment inhibited viability, tube formation, migration, and invasion, and promoted apoptosis in HUVECS, as well as increased Bax and cleaved caspase-3 expressions and decreased Bcl-2 expression. Downregulating miR-141-3p expression promoted viability, tube formation, migration and invasion, and inhibited apoptosis in HUVECs, counteracting the effect of hypoxia on HUVECs. MiR-141-3p directly targeted Notch2. Silencing Notch2 reversed the promoting effect of downregulated miR-141-3p expression on HUVECs. In conclusion, downregulating miR-141-3p expression during hypoxia promotes tube formation, migration, and invasion and inhibits apoptosis in HUVECs by targeting Notch2.

Abstract
Inflammasomes are a group of multiprotein signaling complexes located in the cytoplasm. Several inflammasomes have been identified, including NLRP1, NLRP2, NLRP3, AIM2, and NLRC4. Among them, NLRP3 was investigated in most detail, and it was reported that it can be activated by many different stimuli. Increased NLRP3 protein expression and inflammasome assembly lead to caspase-1 mediated maturation and release of IL-1β, which triggers inflammation and pyroptosis. The activation of the NLRP3 inflammasome has been widely reported in studies of tumors and neurological diseases, but relatively few studies on the cardiovascular system. Ventricular remodeling (VR) is an important factor contributing to heart failure (HF) after myocardial infarction (MI). Consequently, delaying VR is of great significance for improving heart function. Studies have shown that the NLRP3 inflammasome plays an essential role in the process of VR. Here, we reviewed the latest studies on the activation pathway of the NLRP3 inflammasome, focusing on the effects of the NLRP3 inflammasome in primary cells during VR, and finally discuss future research directions in this field.

Abstract
Context: Osteoarthritis (OA) is a degenerative arthrosis sickness. Astragaloside IV (AS-IV) functions by relieving inflammatory damage.Objective: We aimed to investigate the mechanism by which AS-IV protects ATD cells from lipopolysaccharide (LPS)-induced damage.Materials and methods: ATDC5 cells were transfected with miR-203 inhibitor and NC inhibitor (150 nM) or pEX-MyD88 and sh-MyD88 (50 nM) for 48 h, pre-treated by 15 μg/mL AS-IV for 24 h, then treated by 5 μg/mL LPS for 12 h. Dual-luciferase activity testing was used to determine whether miR-203 could bind to MyD88. CCK-8 and flow cytometry were used to detect cell activity and apoptosis, respectively, and qRT-PCR, western blots, and ELISA were performed to detect expression levels of miR-203 and inflammatory cytokines.Results: Based on the 50% inhibiting concentration (IC50), there was no significant difference of AS-IV (0 to 15 μg/mL) on cell viability. Fifteen μg/mL was the optimal concentration of AS-IV in treating LPS-induced inflammatory damage in subsequent experiments since this was a semi-lethal concentration. AS-IV significantly reduces LPS-induced viability, apoptosis and the release of TNF-α, IL-6 and iNOS mainly through up-regulating miR-203. Further, MyD88 was a target gene of miR-203 and negatively regulated by miR-203. Knockdown of MyD88 inhibited LPS-induced inflammatory damage by inhibiting the NF-κB signal pathway.Discussion and conclusions: AS-IV protects ATDC5 cells against LPS-induced damage mainly via regulating miR-203/MyD88. Our results support a theoretical basis for in-depth study of the function of AS-IV and the clinical cure of OA.

Abstract
OBJECTIVES To evaluate the serum levels of the serine proteinase inhibitor kallistatin in women with preeclampsia (PE). METHODS The clinical and laboratory parameters of 55 consecutive women with early-onset PE (EOPE) and 55 consecutive women with late-onset PE (LOPE) were compared with 110 consecutive gestational age (GA)-matched (±1 week) pregnant women with an uncomplicated pregnancy and an appropriate for gestational age fetus. RESULTS Mean serum kallistatin was significantly lower in women with PE compared to the GA-matched-controls (27.74±8.29 ng/mL vs. 37.86±20.64 ng/mL, p<0.001); in women with EOPE compared to that of women in the control group GA-matched for EOPE (24.85±6.65 ng/mL vs. 33.37±17.46 ng/mL, p=0.002); and in women with LOPE compared to that of women in the control group GA-matched for LOPE (30.87±8.81 ng/mL vs. 42.25±22.67 ng/mL, p=0.002). Mean serum kallistatin was significantly lower in women with EOPE compared to LOPE (24.85±6.65 ng/mL vs. 30.87±8.81 ng/mL, p<0.001). Serum kallistatin had negative correlations with systolic and diastolic blood pressure, creatinine, and positive correlation with GA at sampling and GA at birth. CONCLUSIONS Serum kallistatin levels are decreased in preeclamptic pregnancies compared to the GA-matched-controls. This decrease was also significant in women with EOPE compared to LOPE. Serum kallistatin had negative correlation with systolic and diastolic blood pressure, creatinine and positive correlation with GA at sampling and GA at birth.

Abstract
Curative effect of magnesium sulfate combined with nifedipine on pregnancy-induced hypertension and the effect of serum inflammatory factors were investigated. A total of 188 cases of patients were collected as the research subjects. They all had pregnancy-induced hypertension, and were admitted to The First People's Hospital of Yunnan Province hospital from June 2016 to February 2018. There were, 94 patients treated with magnesium sulfate in the control group, and further 94 patients treated with magnesium sulfate combined with nifedipine in the study group. ELISA was used to detect the expression levels of suppressors of cytokine signaling-3 (SOCS-3), interleukin-10 (IL-10) and interleukin 18 (IL-18), and the relationship between serum inflammatory factors and efficacy was analyzed. The curative effect and eutocia rate in the study group were significantly higher than those in the control group (P<0.05), and the cesarean section rate was lower than that of the control group (P<0.05). In the study group, the adverse reactions were significantly lower than those in the control group (P<0.05). After treatment, the expression levels of serum SOCS-3 and IL-10 in the study group were significantly higher than those in the control group (P<0.05), while the expression level of serum IL-18 was significantly lower than that in the control group (P<0.05). The area under the curve (AUC) of the predictive value of SOCS-3, IL-10 and IL-18 in pregnancy-induced hypertension was 0.717, 0.727 and 0.725, respectively. The best specificity was 76.19, 52.98 and 61.90%, respectively, when the cut-off value was <0.553 ng/l, 48.06 ng/ml and 269.46 ng/ml, and their sensitivity was 70.00, 94.74 and 85.00%, respectively. In conclusion, magnesium sulfate combined with nifedipine significantly improved the disease course of pregnancy-induced hypertension. The levels of SOCS-3, IL-10 and IL-18 in patients are correlated with the curative effect of pregnancy-induced hypertension, suggesting that they have important value in the treatment and monitoring of gestational hypertension.

Abstract
PROBLEM To investigate whether downregulation of miR-126-3p and vitamin D receptor (VDR) expression contributes to increased endothelial inflammatory response in preeclampsia. METHODS OF STUDY Maternal vessel miR-126-3p expression was assessed by in situ hybridization. VDR expression and VCAM-1 expression were determined by immunostaining. Subcutaneous adipose tissue sections from normotensive and preeclamptic pregnant women were used. HUVECs from normotensive deliveries were used to test anti-inflammatory effects of vitamin D and miR-126-3p in endothelial cells (ECs) treated with TNFα in vitro. 1,25(OH)2 D3 was used as bioactive vitamin D. Transient overexpression of miR-126-3p in ECs was induced by transfection of pre-mir-126 precursor. Endothelial VCAM-1 and SOCS-3 expression or production was determined by Western blotting or by ELISA, respectively. RESULTS Reduced VDR and miR-126-3p expression, but increased VCAM-1 expression, was observed in maternal vessel endothelium in tissue sections from women with preeclampsia compared to normotensive pregnant controls. Transient overexpression of miR-126-3p not only attenuated upregulation of VCAM-1 expression and production, but also preserved downregulation of SOCS-3 expression, induced by TNFα in ECs. VDR expression and miR-126-3p expression were significantly upregulated in cells treated with 1,25(OH)2 D3 , but not in cells transfected with VDR siRNA. CONCLUSION Downregulation of VDR and miR-126-3p expression was associated with upregulation of VCAM-1 expression in systemic vessel endothelium in preeclampsia. The finding of increased anti-inflammatory property by 1,25(OH)2 D3 through promotion of VDR and miR-126-3p expression in ECs provide plausible evidence that vitamin D deficiency and downregulation of VDR expression could contribute to increased inflammatory phenotypic changes in maternal vasculature in preeclampsia.

Abstract
Dysregulation of circulating microRNAs (miRNAs) in body fluids has been reported in psychiatric disorders such as schizophrenia, bipolar disorder, major depressive disorder, and post-traumatic stress disorder (PTSD). Recent studies of various diseases showed that extracellular vesicles (EV) in body fluids can provide different spectra of circulating miRNAs and disease-associated signatures from whole fluid or EV-depleted fraction. However, the association of miRNAs in EVs to PTSD has not been studied. In this study, we performed a comprehensive profiling of miRNAs in whole plasma, extracellular vesicles (EV) and EV-depleted plasma (EVD) samples collected from combat veterans with PTSD and matched controls by utilizing a next-generation sequencing (NGS) platform. In total, 520 circulating miRNAs were quantified from 24 male Iraq and Afghanistan combat veterans with (n = 12) and without (n = 12) PTSD. The overall miRNA profiles in whole plasma, EV and EVD fractions were different and miRNAs affected by PTSD were also distinct in each sample type. The concentration changes of miR-203a-3p in EV and miR-339-5p in EVD were confirmed in an independent validation cohort that consisted of 20 veterans (10 with and 10 without PTSD) using qPCR. The target genes of these two miRNAs were involved in signaling pathways and comorbid conditions associated with PTSD (e.g., neurotransmitter systems such as dopaminergic and serotonergic signaling, inflammatory response, and cardiovascular diseases). Our findings suggest that PTSD may have different impacts on miRNAs encapsulated in vesicles and outside of vesicles. Further studies using larger samples are needed to evaluate the utility of these miRNAs as diagnostic biomarkers for PTSD.

Abstract
BACKGROUND The pathogenesis of preeclampsia (PE) is suggested to be a consequence of inflammation. Previously conducted investigations on nod-like receptor pyrin domain-containing 3 (NLRP3) have shed light to its crucial role in PE. Furthermore, microRNA-520c-3p (miR-520c-3p) is observed to be implicated in inflammation. Therefore, the current study aimed to explore the role of miR-520c-3p in inflammatory cascade of PE by targeting NLRP3. METHODS Microarray analyses were performed to screen differentially expressed genes associated with PE, and the potential relationship between miR-520c-3p and NLRP3 was analyzed. PE and normal placenta tissues were collected to determine the levels of inflammatory cytokines (IL-18, IL-33, IL-1β, IL-10, and TNF-α), miR-520c-3p and NLRP3. Hypoxic HTR8/SVneo cells were transfected with oe-NLRP3, si-NLRP3 or miR-520c-3p mimic to elucidate the functional role of NLRP3 or miR-520c-3p in the inflammatory cascade in PE, followed by the evaluation of levels of inflammatory cytokines and NLRP3 inflammasomes (NLRP3, ASC and caspase-1). Additionally, the HTR8/SVneo cell migration and invasion were evaluated. RESULTS An upregulation of NLRP3, IL-18, IL-1β and TNF-α, and downregulation of miR-520c-3p, IL-33 and IL-10 were observed in PE placenta tissues. NLRP3 was found to be a target gene of miR-520c-3p. HTR8/SVneo cells after hypoxia transfected with si-NLRP3 or miR-520c-3p mimic exhibited decreased levels of inflammatory cytokines and NLRP3 inflammasomes, in addition to increased IL-10 and IL-33 levels. Moreover, enhanced migration and invasion abilities were observed in cells transfected with si-NLRP3. CONCLUSION Collectively, miR-520c-3p could potentially inhibit NLRP3 inflammasome activation and inflammatory cascade in PE by downregulating NLRP3, highlighting the potential of miR-520c-3p as a therapeutic target for PE treatment.

Abstract
AIMS PMS1 Homolog 2, Mismatch Repair System Component Pseudogene 2 (PMS2L2) has been reported as an up-regulated long non-coding RNA (lncRNA) in osteoarthritis (OA) tissues. The purpose of the present work is to explore whether the differently expressed PMS2L2 is associated with the pathogenesis of OA. MAIN METHODS Chondrogenic ATDC5 cells were exposed to various doses of lipopolysaccharide (LPS). The expression of PMS2L2, miR-203, and MCL-1 in cell was altered by transfection. Thereafter, cell viability, apoptosis, the expression changes of apoptosis-related factors and the release of pro-inflammatory factors were respectively assessed. Moreover, the regulatory relationship between PMS2L2 and miR-203, as well as between miR-203 and MCL-1 were studied. KEY FINDINGS PMS2L2 expression was down-regulated following LPS stimulation. PMS2L2 protected ATDC5 cells against LPS-induced injury by increasing cell viability, decreasing apoptosis, and repressing the release of pro-inflammatory factors. Meanwhile, PMS2L2 increased the expression levels of COL2A1 and ACAN, while down-regulated the expression levels of MMP13 and ADAMTS-5. PMS2L2 worked as a molecular sponge for miR-203. Besides, miR-203 overexpression partially abolished the chondroprotective effects of PMS2L2. MCL-1 was a direct target of miR-203, and it exerted the similarly chondroprotective effects as PMS2L2. Furthermore, PMS2L2 and MCL-1 blocked Wnt/β-Catenin and JAK/STAT signaling pathways also via a miR-203-dependent manner. SIGNIFICANCE Our study reveals a protective role of PMS2L2 in LPS-induced inflammatory injury in chondrocytes. PMS2L2/miR-203/MCL-1 axis may serve as a new gene therapy strategy for the treatment of OA.

Histone deacetylase inhibition disturbs the balance between ACE and chymase expression in endothelial cells: a potential mechanism of chymase activation in preeclampsia. Hypertens Res 2018; 42:155-164.

Abstract
Chymase is a major angiotensin-converting enzyme (ACE)-independent angiotensin convertase, and its expression is upregulated in the maternal vascular endothelium in preeclampsia, a hypertensive disorder in human pregnancy. Increased chymase-dependent angiotensin II generation has been reported in several cardiovascular diseases, including atherosclerosis and aneurysmal lesions. However, it remains unclear how chymase is activated. Histone modification is an important regulatory mechanism that controls gene expression. In this study, using a chymase overexpression cell model, we investigated the mechanisms of chymase activation to test our hypothesis that histone acetylation could promote endothelial chymase expression. Human umbilical vein endothelial cells were transfected with the chymase gene. Trichostatin A was used to inhibit histone deacetylases (HDACs). The expression levels of chymase, ACE, and HDACs were determined by western blotting. Our results showed that ACE was strongly expressed in control cells, but was significantly downregulated in cells transfected to express chymase. Strikingly, we also found that HDAC inhibition resulted in a dose-dependent increase in chymase expression but a dose-dependent decrease in ACE expression in cells transfected with the chymase gene. HDAC inhibition was confirmed by the decreased expression of HDAC1 and HDAC6 in cells treated with trichostatin A. Increased chymase expression associated with reduced histone deacetylase expression was further confirmed by immunostaining of subcutaneous adipose sections from women with preeclampsia. We conclude that aberrant HDAC expression/activity could disturb the balance between ACE and chymase expression in endothelial cells. Our results support the clinical importance of chymase as a new pharmacological target for cardiovascular disorders.

Abstract
PROBLEM To study the role of miRNA(s) during trophoblastic BeWo cell fusion. METHOD OF STUDY Changes in miRNA(s) profile of BeWo cells treated with forskolin were analyzed using Affymetrix miRNA microarray platform. Down-regulated miRNA, miR-92a-1-5p, was overexpressed in BeWo cells followed by forskolin treatment to understand its relevance in the process of BeWo cell fusion by desmoplakin I+II staining and hCG secretion by ELISA. Predicted targets of miR-92a-1-5p were also confirmed by qRT-PCR/Western blotting. RESULTS The miRNA profiling of BeWo cells after forskolin (25 μmol/L) treatment identified miR-92a-1-5p as the most significantly down-regulated miRNA both at 24 and 48 hours time points. Overexpression of miR-92a-1-5p in these cells led to a significant decrease in forskolin-mediated cell fusion and hCG secretion. miRNA target prediction software, TargetScan, revealed dysferlin (DYSF) and protein kinase cAMP-activated catalytic subunit alpha (PRKACA), as target genes of miR-92a-1-5p. Overexpression of miR-92a-1-5p in BeWo cells showed reduction in forskolin-induced transcripts for DYSF and PRKACA. Further, reduction in DYSF (~2.6-fold) at protein level and PRKACA-encoded protein kinase A catalytic subunit alpha (PKAC-α; ~1.6-fold) were also observed. CONCLUSION These observations suggest that miR-92a-1-5p regulates forskolin-mediated BeWo cell fusion and hCG secretion by regulating PKA signaling pathway and dysferlin expression.

Abstract
Chymase is an ACE (angiotensin-converting enzyme)-independent angiotensin II-forming enzyme whose expression is increased in the maternal vascular endothelium in preeclampsia. However, mechanisms underlying chymase activation in preeclampsia remain unclear. Cathepsin C is a key enzyme in the activation of several serine proteases including chymase. In this study, we determined whether increased cathepsin C expression/activity might be responsible for the upregulation of chymase expression in preeclampsia. Maternal vascular cathepsin C, chymase and ACE expression were examined through immunohistochemical staining of subcutaneous fat tissue sections of normal and preeclamptic pregnant women. The role of cathepsin C in endothelial chymase and ACE expression was determined in cells treated with cathepsin C. Consequences of chymase activation were then determined by measurement of angiotensin II production in cells treated with the ACE inhibitor captopril and the chymase inhibitor chymostatin, separately and in combination. Expression of both cathepsin C and chymase, but not ACE expression, was markedly increased in the maternal vascular endothelium in subjects with preeclampsia compared with normal pregnant controls. Exogenous cathepsin C induced a dose-dependent increase in expression of mature cathepsin C and chymase, but not ACE, in endothelial cells. Moreover, angiotensin II production was significantly inhibited in cells treated with captopril or chymostatin alone and was further inhibited in cells treated with both inhibitors. These results suggest that cathepsin C upregulation induces chymase activation and subsequently promotes angiotensin II generation in endothelial cells. These data also provide evidence of upregulation of the cathepsin C-chymase-angiotensin signaling axis in maternal vasculature in preeclampsia.

Abstract
Endometriosis is an inflammatory pathology associated with a negative effect on life quality. Recently, this pathology was connected to ovarian cancer, in particular with endometrioid ovarian cancer. microRNAs (miRNAs) are a class of RNA transcripts ~19–22 nucleotides in length, the altered miRNA pattern being connected to pathological status. miRNAs are highly stable transcripts, and these can be assessed from formalin-fixed paraffin-embedded (FFPE) samples leading to the identification of miRNAs that could be developed as diagnostic and prognostic biomarkers, in particular those involved in malignant transformation. The aim of our study was to evaluate miRNA expression pattern in FFPE samples from endometriosis and ovarian cancer patients using PCR-array technology and also to compare the differential expression pattern in ovarian cancer versus endometriosis. For the PCR-array study, we have used nine macrodissected FFPE samples from endometriosis tissue, eight samples of ovarian cancers and five normal ovarian tissues. Quantitative real-time PCR (qRT-PCR) was used for data validation in a new patient cohort of 17 normal samples, 33 endometriosis samples and 28 ovarian cancer macrodissected FFPE samples. Considering 1.5-fold expression difference as a cut-off level and a P-value <0.05, we have identified four miRNAs being overexpressed in endometrial tissue, while in ovarian cancer 15 were differentially expressed (nine overexpressed and six downregulated). The expression level was confirmed by qRT-PCR for miR-93, miR-141, miR-155, miR-429, miR-200c, miR-205 and miR-492. Using the interpretative program Ingenuity Pathway Analysis revealed several deregulated pathways due to abnormal miRNA expression in endometriosis and ovarian cancer, which in turn is responsible for pathogenesis; this differential expression of miRNAs can be exploited as a therapeutic target. A higher number of altered miRNAs were detected in endometriosis versus ovarian cancer tissue, most of them being linked with epithelial-to-mesenchymal transition.
