Cui X, Zhu G, Han M, Li X, Lou S, Xing C, Xu S, Pan Y, Wang L. Genetic variants in BCL-2 family genes influence the risk of non-syndromic cleft lip with or without cleft palate. Birth Defects Res 2024; 116:e2288. [PMID: 38108593 DOI: 10.1002/bdr2.2288] [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: 07/31/2023] [Revised: 09/30/2023] [Accepted: 12/02/2023] [Indexed: 12/19/2023]
Abstract
BACKGROUND The BCL-2 family is crucial for cell death regulation and is involved in development, tissue homeostasis, and immunity. This study aimed to investigate the association between genetic variants in BCL-2 family genes and non-syndromic cleft lip with or without cleft palate (NSCL/P) risk. METHODS A two-stage case-control study was conducted in this association study. Gene-based analysis using Multi-marker Analysis of GenoMic Annotation was performed in the first stage cohort, which included 565 cases and 1269 controls. A logistic regression model was employed to assess the effect of single nucleotide polymorphisms (SNPs) on susceptibility to NSCL/P. Candidate SNPs were replicated by extra dbGaP case-parent trios. Haploreg, RegulomeDB, and UCSC Genome Browser were used to identify enhancer effects of promising SNPs. Bulk RNA sequencing data obtained from the Gene Expression Omnibus was used to identify co-expressed genes. Single-cell RNA sequencing dataset was used to infer the cell population of the candidate gene. The "Monocle" package was used to analyze the pseudotime cell trajectories. RESULTS Rs3943258 located in the enhancer region was associated with the risk of NSCL/P (Pmeta = 5.66 × 10-04 ) and exhibited an eQTL effect for BCL2 (P = 3.96 × 10-02 ). Co-expression and pathway enrichment analysis revealed that genes related to Bcl2 were significantly enriched in the PI3K-Akt signaling pathway, MAPK signaling pathway, and Wnt signaling pathway. Five cell clusters were identified in single-cell RNA sequencing, and Bcl2 was mainly located in the mesenchyme. CONCLUSION The rs3943258 located within BCL2 was probably related to NSCL/P susceptibility.

Abstract
Acute liver failure (ALF) is a severe liver disease with a high mortality rate without effective therapeutic drugs. Ferroptosis is a form of programmed cell death that plays an important role in ALF. In this study, we aimed to identify ferroptosis-related genes in ALF, thereby predicting promising compounds to treat ALF. First, mRNA microarray data were utilized to identify the ferroptosis-related differentially expressed genes (DEGs). Hub genes were screened in the protein-protein interaction network and validated. Subsequently, potential drugs to treat ALF were predicted. One of the predicted drugs was tested in an ALF model of mice. Ferroptosis examination and molecular docking were analyzed to explore the mechanism. A total of 37 DEGs were identified, ten hub genes were extracted, and their expression in ALF was validated. The predicted drug niclosamide mitigated lipopolysaccharide/D-galactosamine-induced hepatotoxicity, and decreased mortality of mice in the ALF model. Mechanically, niclosamide may combine with signal transducer and activator of transcription 3 to inhibit ALF progression by suppressing ferroptosis. This study may help advance our understanding of the role of ferroptosis in ALF, and niclosamide may be promising for therapeutic efficacy in patients with ALF.

Abstract
Aims: This study aims to investigate the function of positive feedback loops involving noncoding RNA in diabetic wound healing. Methods: We developed a mouse diabetic wound model to confirm that hyperglycemia can impair wound healing. We also used an in vitro keratinocyte model in high-glucose conditions to investigate the mechanism of delayed wound healing. Results: MALAT1 was decreased in diabetic mouse wound tissue and can promote keratinocyte biological functions. MALAT1 could bind to miR-106a-5p to modulate the expression of ZNF148, a target gene of miR-106a-5p. Surprisingly, ZNF148 bound to a region in the MALAT1 promoter to stimulate gene expression. Conclusion: ZNF148-activated MALAT1 increases ZNF148 expression by competitively binding miR-106a-3p, generating a positive feedback loop that enhances keratinocyte function.

Abstract
Cleft lip and palate is one of the most common congenital birth defects and has a complex etiology. Either genetic or environmental factors, or both, are involved at various degrees, and the type and severity of clefts vary. One of the longstanding questions is how environmental factors lead to craniofacial developmental anomalies. Recent studies highlight non-coding RNAs as potential epigenetic regulators in cleft lip and palate. In this review, we will discuss microRNAs, a type of small non-coding RNAs that can simultaneously regulate expression of many downstream target genes, as a causative mechanism of cleft lip and palate in humans and mice.

Abstract
TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin) is a ubiquitous environmental toxicant and a notable teratogenic agent for cleft palate (CP), a common congenital structural malformation that can result from abnormalities during palatal shelf connection and/or fusion. The development of the palate requires precise coordination between mesenchymal and epithelial cells. Exosomes are vesicles secreted by cells and participate in organ development by transferring various bioactive molecules between cells and regulating cell proliferation, migration, apoptosis, and epithelial-mesenchymal transition (EMT); these vesicles represent a new method of intercellular communication. To explore how TCDD could influence palatal cell behaviors and communication, we treated mesenchymal cells with TCDD, collected the exosomes secreted by the cells, assessed the 2 types of palatal cells, and then observed the effects of TCDD-induced exosomes. We found that the effects of TCDD-induced exosomes were equal to those of TCDD. Thus, TCDD might change the genetic materials of palatal cells and exosomes to cause dysregulated gene expression from parental cells, affect cellular information communicators, and induce abnormal cellular behaviors that could lead to CP.

Abstract
MicroARNAs (miRNAs) are linked to a variety of cancers, which resulted in molecular pathway dysregulation in chronic lymphocytic leukemia (CLL). Using five dysregulated miRNAs identified by literature mining and in silico analysis, we were able to demonstrate the critical role that the TGFBR1 and TGFB receptor signaling pathways play in the state of CLL. Assays using real-time PCR were run on 30 patients and 30 healthy controls. This study showed that patient samples have considerably higher levels of miR-574 and miR-499. Notably, the same groups had lower expression levels of miR-125b, miR-106a, and miR-9. Furthermore, we suggested that TGFBR1 and TGFBR2 expression levels were decreased in patients, and we suggested that these genes could be targets for our profile miRNAs. In the current study, we hypothesized that miR-574, miR-499, miR-125b, miR-106a, and miR-9 are likely five new potential biomarkers for early diagnosis. Our research also showed that these profile miRNAs have a role in the formation of CLL, possibly through controlling the TGFBR1 and TGFBR2 pathways. This suggests that these profile miRNAs could serve as biomarkers for the diagnosis and prognosis of CLL.

Abstract
Background Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a common craniofacial birth defect. Growing evidence has demonstrated the competing endogenous RNA (ceRNA) hypothesis has played a role in the pathogenesis of NSCL/P. Here, we identified the important lncRNAs in NSCL/P and constructed a ceRNA regulatory network to predict their underlying functional mechanism. Methods Total RNA isolated from the peripheral blood samples were analyzed by the Human Clariom D Affymetrix platform and differentially expressed genes (DEGs) were identified. Using the limma package in R software, DEGs in the expression profile of GSE42589 were identified from Gene Expression Omnibus (GEO) database. Co-differentially expressed lncRNAs (co-DElncRNAs) were used to predict the microRNAs that may bind to them. Co-differentially expressed mRNAs (co-DEmRNAs) were subjected to Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. The hub genes were screened using the cytohubba plug-in in Cytoscape. A ceRNA network was built to investigate the molecular mechanism underlying the etiology of NSCL/P. The expression levels of lncRNAs, miRNAs, and mRNAs in the network were assessed by quantitative real-time polymerase chain reaction (qRT-PCR). Results We found 116 DElncRNAs and 2955 DEmRNAs from the GSE42589 dataset, and 2626 DElncRNAs and 2771 DEmRNAs from the Human Clariom D gene chip. A network of co-DEmRNAs containing 3712 edges and 621 nodes were identified by PPI analysis. A ceRNA regulatory network comprising lncRNA USP17L6P, hsa-miR-449c-5p, and MYC was established. qRT-PCR results revealed significantly lower expression levels of lncRNA USP17L6P and c-Myc in NSCL/P tissues, while the expression level of hsa-miR-449c-5p was higher as compared to control samples (p < 0.05). Conclusion The identified lncRNAs and the established ceRNA regulatory network provide novel insight into the pathogenesis of NSCL/P, therefore hold great promise in NSCL/P management in clinical practice.

Abstract
Cleft lip with or without cleft palate (CL/P) is one of the most common congenital birth defects. This study aims to identify novel pathogenic microRNAs associated with cleft palate (CP). Through data analyses of miRNA-sequencing for developing palatal shelves of C57BL/6J mice, we found that miR-449a-3p, miR-449a-5p, miR-449b, miR-449c-3p, and miR-449c-5p were significantly upregulated, and that miR-19a-3p, miR-130a-3p, miR-301a-3p, and miR-486b-5p were significantly downregulated, at embryonic day E14.5 compared to E13.5. Among them, overexpression of the miR-449 family (miR-449a-3p, miR-449a-5p, miR-449b, miR-449c-3p, and miR-449c-5p) and miR-486b-5p resulted in reduced cell proliferation in primary mouse embryonic palatal mesenchymal (MEPM) cells and mouse cranial neural crest cell line O9-1. On the other hand, inhibitors of miR-130a-3p and miR-301a-3p significantly reduced cell proliferation in MEPM and O9-1 cells. Notably, we found that treatment with dexamethasone, a glucocorticoid known to induce CP in mice, suppressed miR-130a-3p expression in both MEPM and O9-1 cells. Moreover, a miR-130a-3p mimic could ameliorate the cell proliferation defect induced by dexamethasone through normalization of Slc24a2 expression. Taken together, our results suggest that miR-130-3p plays a crucial role in dexamethasone-induced CP in mice.

Abstract
Objective This article summarizes the recent literature on noncoding ribonucleic acids (ncRNAs) in relation to cleft lip with or without palate and exosomes and their usage in craniofacial diseases. Background Cleft lip with or without cleft palate (CL/P) is a common congenital malformation with genetic and environmental risk factors that affects numerous children and families. Surgical procedures can correct deformations; however, residual sequelae remain after surgery. Studies exploring the pathogenesis of CL/P are crucial for its early diagnosis and treatment and can inform treatment strategy decisions, etiology searches, and treatment during pregnancy. Recently, research has shown that most disease-related genes are ncRNAs, which are important transcripts in the human transcriptome. ncRNAs include microRNAs, long noncoding RNAs, and circular RNAs. These ncRNAs play essential roles in various pathophysiological processes, including cell proliferation, migration, apoptosis, and epithelial-mesenchymal transition. Previous studies on protein-coding genes have identified a number of genes related to CL/P; however, the pathogenesis of CL/P has not yet been thoroughly explained. Exosomes are vehicles that transfer various bioactive molecules between cells and represent a new method of intercellular communication. Research has shown that exosomes are related to some craniofacial diseases. Methods We searched the PubMed database for recently published English-language articles using the following keywords: “cleft lip with or without palate,” “noncoding RNA,” “exosomes,” and “craniofacial diseases”. We then reviewed the retrieved articles. Conclusions As exosomes serve as cellular communicators and the palate consists of epithelial and mesenchymal cells, communication between the two cell types may affect its formation. Thus, exosomes could represent a new indicator and mediator of CL/P.

The role of lncRNA Meg3 in the proliferation of all-trans retinoic acid-treated mouse embryonic palate mesenchymal cells involves the Smad pathway. Reprod Toxicol 2021; 104:1-7. [PMID: 34166781 DOI: 10.1016/j.reprotox.2021.06.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Revised: 05/25/2021] [Accepted: 06/18/2021] [Indexed: 11/27/2022]
Abstract
Mesenchymal cell proliferation is critical for the growth of the palate shelf. All-trans retinoic acid (atRA), as well as pathways associated with TGF-β/Smad signaling, play crucial roles in the proliferation of mouse embryonic palate mesenchymal (MEPM) cells. We have found that MEPM-cell proliferation was regulated by atRA and exogenous TGF-β3 could significantly antagonize the atRA-mediated suppression of MEPM cell proliferation, which is closely associated with the regulation of TGF-β/Smad signaling pathway. The long non-coding RNA (lncRNA) MEG3 has been reported to activate TGF-β/Smad signaling, thereby regulating cellular proliferation, differentiation, and related processes. Here, we found that Meg3 expression increased significantly in atRA-treated MEPM cells while TGF-β3 treatment markedly inhibited Meg3 expression and antagonized the effect of atRA on Meg3. Moreover, Smad2 was found to interact directly with Meg3, and atRA treatment significantly enriched Meg3 in Smad2-immunoprecipitated samples. After Meg3 deletion, the effects of atRA on the proliferation of MEPM cells and TGF-β3-dependent protein expression were lost. Hence, we speculate that Meg3 has a role in the RA-induced suppression of MEPM cell proliferation by targeting Smad2 and thereby mediating TGF-β/Smad signaling inhibition.

[PMID: 33493612 DOI: 10.1016/j.toxlet.2021.01.017] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2020] [Revised: 01/05/2021] [Accepted: 01/18/2021] [Indexed: 12/15/2022]
Abstract
Palatal mesenchymal cell proliferation is essential to the process of palatogenesis, and the proliferation of mouse embryonic palate mesenchymal (MEPM) cells is impacted by both all-trans retinoic acid (atRA) and the TGF-β/Smad signaling pathway. The long non-coding RNA (lncRNA) MEG3 has been shown to activate TGF-β/Smad signaling and to thereby regulate cell proliferation, differentiation, and related processes. Herein, we found that atRA treatment (100 mg/kg) promoted Meg3 upregulation in MEPM cells, and that such upregulation was linked to the suppression of MEPM cell proliferation in the context of secondary palate fusion on gestational day (GD) 13 and 14. Moreover, the demethylation of specific CpG sites within the lncRNA Meg3 promoter was detected in atRA-treated MEPM cells, likely explaining the observed upregulation of this lncRNA. Smad signaling was also suppressed by atRA treatment in these cells, and RNA immunoprecipitation analyses revealed that Smad2 can directly interact with Meg3 in MEPM cells following atRA treatment. Therefore, we propose a model wherein Meg3 is involved in the suppression of MEPM cell proliferation, functioning at least in part via interacting with the Smad2 protein and thereby suppressing Smad signaling in the context of atRA-induced cleft palate.

Abstract
Cleft lip (CL) with/without cleft palate (CP) (hereafter CL/P) is the second most common congenital birth defect, affecting 7.94 to 9.92 children per 10,000 live births worldwide, followed by Down syndrome. An increasing number of genes have been identified as affecting susceptibility and/or as causative genes for CL/P in mouse genetic and chemically-induced CL and CP studies, as well as in human genome-wide association studies and linkage analysis. While marked progress has been made in the identification of genetic and environmental risk factors for CL/P, the interplays between these factors are not yet fully understood. This review aims to summarize our current knowledge of CL and CP from genetically engineered mouse models and environmental factors that have been studied in mice. Understanding the regulatory mechanism(s) of craniofacial development may not only advance our understanding of craniofacial developmental biology, but could also provide approaches for the prevention of birth defects and for tissue engineering in craniofacial tissue regeneration.

Abstract
Orofacial clefts (OFCs) have multiple etiologies and likely result from an interplay between genetic and environmental factors. Within the last decade, studies have implicated specific epigenetic modifications and noncoding RNAs as additional facets of OFC etiology. Altered gene expression through DNA methylation and histone modification offer novel insights into how specific genes contribute to distinct OFC subtypes. Epigenetics research has also provided further evidence that cleft lip only (CLO) is a cleft subtype with distinct etiology. Polymorphisms or misexpression of genes encoding microRNAs, as well as their targets, contribute to OFC risk. The ability to experimentally manipulate epigenetic changes and noncoding RNAs in animal models, such as zebrafish, Xenopus, mice, and rats, has offered novel insights into the mechanisms of various OFC subtypes. Although much remains to be understood, recent advancements in our understanding of OFC etiology may advise future strategies of research and preventive care.

Abstract
BACKGROUND Recent studies have shown that lipid metabolism was abnormal during the formation of cleft palate. However, the composition of these lipid species remains unclear. OBJECTIVE Aims of this study were to identify the lipid species components and reveal the key lipid metabolic disorders in cleft palate formation. METHODS The pregnant mice were divided into experimental group exposed to all-trans retinoic acid (RA-treated group) (n = 12) and control group (n = 12) at embryonic gestation day 10.5 (E0.5). The component of the palatal tissue metabolome was analyzed using a LCMS-based nontargeted lipidomics approach. Multivariate statistical analysis was then carried out to assess the differences between the RA-treated group and the control group. RESULTS Twenty-nine lipid species were found to discriminate between RA-treated and control embryos. Among them, 28 lipid species increased and 1 lipid species decreased in the RA-treated group. Among these lipids, 13 were triglycerides, 9 were PEs, 3 were PCs, 2 were PSs, 2 were DGs. Further analysis of the number of carbons and unsaturated bond of triglycerides showed that TGs with high unsaturated bonds constituted a higher fraction in the RA-treated group. A higher amount of triglycerides containing 52, 54, 56, 58, 60 carbons, and 1 to 8 unsaturated bonds. Of note, under RA treatment, TG 50:1, 52:2, 56:6and 60:8 became the most prominent. CONCLUSION Lipid metabolism is significantly different in the formation of cleft palate induced by RA, and the unsaturated triglycerides increased in the RA-treated group may play an important role in the formation of cleft palate.

Abstract
Aim: To identify a key competitive endogenous RNA network for intervertebral disc degeneration. Materials & methods: Based on circular RNA, microRNA and mRNA expression profiles of nucleus pulposus cells, a variety of bioinformatics methods were used to screen key molecular structures and construct competitive endogenous RNA networks. Results: 190 upregulated genes and 77 downregulated genes were identified. Gene ontology/Kyoto Encyclopedia of Genes and Genomes functional analysis showed that autophagy was out of balance with apoptosis. Nine hub genes, five hub microRNAs and eight hub circular RNAs were obtained through progressive reverse prediction and verification. Conclusion: We believe that disc degeneration is caused by an imbalance between autophagy and apoptosis in nucleus pulposus cells, which may provide nonsurgical treatment for the future delay or prevention of spinal degenerative diseases associated with intervertebral disc degeneration.
