Abstract
Long non-coding RNAs (lncRNAs) are versatile RNAs that regulate various cellular processes, such as gene regulation, by acting as signals, decoys, guides, and scaffolds. A novel recognized lncRNA, LOXL1-antisense RNA 1 (LOXL1-AS1), is dysregulated in some diseases, including cancer, and acts as an oncogenic lncRNA in many types of cancer cells. Upregulation of LOXL1-AS1 has been involved in proliferation, migration, metastasis, and EMT, as well as inhibiting apoptosis in cancer cells. Most importantly, the malignant promoting activity of LOXL1-AS1 can be mostly mediated by sequestering specific miRNAs and inhibiting their binding to the 3´UTR of their target mRNAs, thereby indirectly regulating gene expression. Additionally, LOXL1-AS1 can decoy transcription factors and proteins and prevent their binding to their regulatory regions, inhibiting their mechanistic activity on the regulation of gene expression and signaling pathways. This review presents the mechanistic pathways of the oncogenic role of LOXL1-AS1 by modulating its target miRNAs and proteins in various cancer cells. Having information about the molecular mechanisms regulated by LOXL1-AS1 in cancer cells can open ways to find out particular prognostic biomarkers, as well as discover novel therapeutic approaches for different types of cancer.

Abstract
ABSTRACT Accumulating studies have demonstrated that non-coding RNAs (ncRNAs), functioning as important regulators of transcription and translation, are involved in the establishment and maintenance of pregnancy, especially the maternal immune adaptation process. The endometrial stromal cells (ESCs), trophoblast cells, and decidua immune cells that reside at the maternal-fetal interface are thought to play significant roles in normal pregnancy and pregnancy-associated diseases. Here, we reviewed the up-to-date evidence on how microRNA, long non-coding RNA, and circular RNA regulate ESCs, trophoblast cells, and immune cells and discussed the potential applications of these ncRNAs as diagnostic and therapeutic markers in pregnancy complications.

Abstract
Preeclampsia (PE) refers to a pregnancy-specific disease that begins with the placenta. Differentially expressed microRNAs (miRs) are a feature of PE. This study tried to elicit the functional mechanism of miR-515-5p in trophoblast cell behaviors in PE. First, HTR-8/SVneo cells were transfected with miR-515-5p mimic or miR-515-5p inhibitor. Then, relative expression levels of miR-515-5p and histone deacetylase 2 (HDAC2) in HTR-8/SVneo cells were determined by reverse transcription-quantitative polymerase chain reaction. The potential binding site of miR-515-5p and HDAC2 was predicted on Targetscan and their binding relationship was verified via dual-luciferase assay. Proliferation, apoptosis, invasion, and migration of HTR-8/SVneo cells were assessed via cell counting kit-8, flow cytometry, Transwell, and wound healing assays, respectively. Protein levels of Cleaved caspase-3, Bcl-2, and Bax were determined via Western blot. Overexpressed miR-515-5p impeded proliferation and stimulated apoptosis of HTR-8/SVneo cells, and decreased levels of Cleaved caspase-3 and Bax and elevated Bcl-2, whilst opposite results were observed after miR-515-5p inhibition. miR-515-5p targeted HDAC2. Knockdown of HDAC2 annulled the promotional action of miR-515-5p inhibition on proliferative, invasive, and migratory abilities and its antiapoptotic action on HTR-8/SVneo cells. In brief, miR-515-5p affected the proliferation, apoptosis, invasion, and migration of HTR-8/SVneo cells by targeting HDAC2.

Abstract
The pathophysiology of endometriosis remains poorly understood. The aim of the present study was to investigate functions and pathways associated with the various miRNAs differentially expressed in patients with endometriosis. Plasma samples of the 200 patients from the prospective "ENDO-miRNA" study were analyzed and all known human miRNAs were sequenced. For each miRNA, sensitivity, specificity, and ROC AUC values were calculated for the diagnosis of endometriosis. miRNAs with an AUC ≥ 0.6 were selected for further analysis. A comprehensive review of recent articles from the PubMed, Clinical Trials.gov, Cochrane Library, and Web of Science databases was performed to identify functions and pathways associated with the selected miRNAs. In total, 2633 miRNAs were found in the patients with endometriosis. Among the 57 miRNAs with an AUC ≥ 0.6: 20 had never been reported before; one (miR-124-3p) had previously been observed in endometriosis; and the remaining 36 had been reported in benign and malignant disorders. miR-124-3p is involved in ectopic endometrial cell proliferation and invasion and plays a role in the following pathways: mTOR, STAT3, PI3K/Akt, NF-κB, ERK, PLGF-ROS, FGF2-FGFR, MAPK, GSK3B/β-catenin. Most of the remaining 36 miRNAs are involved in carcinogenesis through cell proliferation, apoptosis, and invasion. The three main pathways involved are Wnt/β-catenin, PI3K/Akt, and NF-KB. Our results provide evidence of the relation between the miRNA profiles of patients with endometriosis and various signaling pathways implicated in its pathophysiology.

Abstract
Choriocarcinoma is an aggressive gestational trophoblastic neoplasm. This study attempted to explore the biological functions and underlying mechanisms by which ropivacaine restrains the progression of choriocarcinoma. The expression of long noncoding RNA OGFRP1, microRNA-4731-5p (miR-4731-5p), and HIF3A in choriocarcinoma cells was assessed by qRT-PCR. Choriocarcinoma cells treated with ropivacaine at the concentration of 100, 500, and 1000 μM were cultured for 24, 48, and 72 h, respectively. Choriocarcinoma cell viability was evaluated by MTT assay. Transwell assay was conducted to examine choriocarcinoma cell migration and invasion. Additionally, the target relationship between OGFRP1 and miR-4731-5p or between miR-4731-5p and HIF3A was predicted by bioinformatics analysis and confirmed by dual-luciferase reporter assays. OGFRP1 and HIF3A expression were enhanced in choriocarcinoma cells, while miR-4731-5p expression was inhibited. Treatment with ropivacaine impeded choriocarcinoma cell viability, migration, and invasion. Choriocarcinoma cells treated with 1000 μM ropivacaine for 48 h were selected for subsequent experiments. OGFRP1 elevation or miR-4731-5p deficiency mitigated the reduction effect of ropivacaine on tumorigenesis of choriocarcinoma cells. Besides, miR-4731-5p was predicted as the potential OGFRP1 target by StarBase and LncBase, and HIF3A was predicted as the potential miR-4731-5p target by StarBase and TargetScan. Dual-luciferase reporter assays determined that miR-4731-5p was a target of OGFRP1 and HIF3A was a target of miR-4731-5p. Feedback experiments declared that miR-4731-5p elevation or HIF3A suppression reversed the promoting effect of OGFRP1 overexpression on the malignant behaviors of ropivacaine-treated choriocarcinoma cells. Ropivacaine constrained choriocarcinoma cell viability, migration, and invasion through modulating the OGFRP1/miR-4731-5p/HIF3A axis. Our study may provide a novel strategy for choriocarcinoma prevention and treatment.

Abstract
Background Numerous studies have demonstrated that noncoding RNAs are involved in choriocarcinoma (CC). The competing endogenous RNA (ceRNA) network plays an important role in the occurrence and development of carcinoma. However, the involvement of the ceRNA network in CC remains unclear. The current study aimed to investigate the regulatory mechanism of ceRNA in CC. Material/Methods We downloaded the messenger RNAs (mRNAs) expression profiles (GSE20510 and GSE65654) and microRNAs (miRNAs) expression profiles (GSE32346 and GSE130489) from GEO datasets. The limma package of R software was used to identify differentially expressed RNAs (DERNAs). Then, we performed functional annotation of the differentially expressed mRNAs (DEmRNAs). TargetScan, miRDB, miRWalk, and Starbase were used to construct a CC-specific ceRNA network and select key molecules. Results The results identified a total of 177 DEmRNAs and 189 differentially expressed miRNAs (DEmiRNAs) between the trophoblast and CC cell line samples. Ten differentially expressed lncRNAs (DElncRNAs) were obtained based on experimental studies. The DEmRNAs were mainly enriched in cell proliferation, positive regulation of the apoptotic process, and cell death. A total of 10 genes were ascertained as hub genes. Based on DEmRNAs, DEmiRNAs, and DElncRNAs, a CC-specific ceRNA network was established. Five DElncRNAs, 15 DEmiRNAs, and 45 DEmRNAs were identified. In addition, LINC00261, MEG3, MALAT1, H19, and OGFRP1 were identified as 5 key lncRNAs in choriocarcinoma. Conclusions This study provides novel insights into CC mechanisms and identified potential therapeutic targets for CC.

Cell Cycle 2021:1-18. [PMID: 34382896 DOI: 10.1080/15384101.2021.1958501] [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: 11/16/2020] [Revised: 06/24/2021] [Accepted: 07/16/2021] [Indexed: 10/20/2022] Open
Abstract
Increasing evidences have confirmed that long non-coding RNA LOXL1-AS1 functions in multiple human diseases. Here, we aim to explore the function and mechanism of LOXL1-AS1 in modulating oxidized low-density lipoprotein (ox-LDL)-induced angiogenesis of endothelial cells (ECs). Presently, we found that LOXL1-AS1 and KLF6 were upregulated in ECs treated by Ox-LDL in a dose- and time-dependent manner while miR-590-5p was downregulated. Overexpression of LOXL1-AS1 aggravated Ox-LDL mediated ECs proliferation and migration, and promoted angiogenesis both in vitro and in vivo. On the contrary, enhancing miR-590-5p or inhibiting LOXL1-AS1 level led to suppressive effects on the proliferation, migration and angiogenesis of ECs. Moreover, LOXL1-AS1 upregulation promoted the expression of vascular endothelial growth factor (VEGF), MMPs (including MMP2, MMP9, and MMP14) and also activated VEGF/VEGFR2/PI3K/Akt/eNOS pathway. Mechanistically, LOXL1-AS1 works as a competitive endogenous RNA (ceRNA) by sponging miR-590-5p, which targeted at the 3'-untranslated region (3'UTR) of KLF6. Additionally, the proliferation, migration, and angiogenesis of ECs were elevated following KLF6 upregulation. By detecting the expression of LOXL1-AS1 and miR-590-5p in the serum of healthy donors and atherosclerosis patients, it was found that LOXL1-AS1 was upregulated in atherosclerosis patients (compared with healthy donors) and had a negative relationship with miR-590-5p. Taken together, LOXL1-AS1 promoted Ox-LDL induced angiogenesis via regulating miR-590-5p-modulated KLF6/VEGF signaling pathway. The LOXL1-AS1-miR-590-5p axis exerts a novel role in the progression of atherosclerosis.
