Abstract
Hirschsprung's disease (HSCR) is a congenital disorder characterized by the absence of ganglion cells in the colon, leading to various intestinal complications. The etiology of HSCR stems from complex genetic and environmental interactions, of which the intricate roles of non-coding RNAs (ncRNAs) are a key area of research. However, the roles of ncRNAs in the pathogenesis of HSCR have not been fully elucidated. In order to understand the variety of symptoms caused by HSCR and develop new therapeutic approaches, it is essential to understand the underlying biological genetic basis of HSCR. This review presents a comprehensive overview of the current understanding regarding the involvement of ncRNAs in HSCR, including microRNAs (miRNAs), long noncoding RNAs (lncRNAs), and circular RNAs (circRNAs). Additionally, it provides a summary of the molecular mechanisms through which ncRNAs regulate the expression of genes related to the proliferation, migration, and differentiation of intestinal neural crest cells, thereby contributing to the advancement of HSCR research.

ZEB2 alleviates Hirschsprung's-associated enterocolitis by promoting the proliferation and differentiation of enteric neural precursor cells via the Notch-1/Jagged-2 pathway. Gene 2024; 912:148365. [PMID: 38485033 DOI: 10.1016/j.gene.2024.148365] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2023] [Revised: 02/20/2024] [Accepted: 03/11/2024] [Indexed: 03/18/2024]
Abstract
BACKGROUND Hirschsprung's-associated enterocolitis (HAEC) is a prevalent complication of Hirschsprung's disease (HSCR). Zinc finger E-box binding homeobox 2 (ZEB2) and Notch-1/Jagged-2 are dysregulated in HSCR, but their role in HAEC progression remains poorly understood. We aimed to explore the role and underlying mechanism of enteric neural precursor cells (ENPCs) and the ZEB2/Notch-1/Jagged-2 pathway in HAEC development. METHODS Colon tissues were collected from HSCR and HAEC patients. ENPCs were isolated from the HAEC group and stimulated by lipopolysaccharide (LPS). The expressions of ZEB2/Notch-1/Jagged-2 were measured using RT-qPCR and Western blot. Immunofluorescence and cell counting kit-8 assays were performed to assess the differentiation and proliferation of ENPCs. Inflammatory factors were measured by ELISA kits. Co-immunoprecipitation and bioinformatic analysis were used to explore the interaction between ZEB2 and Notch-1. Small interfering RNA and overexpression vectors were used to investigate the role and mechanism of ZEB2 and Notch-1 in regulating ENPCs' proliferation and differentiation during HAEC progression. RESULTS We observed increased LPS in the colon tissues of HAEC, with downregulated ZEB2 expression and upregulated Notch-1/Jagged-2 expression. ZEB2 interacts with Notch-1. LPS treatment downregulated ZEB2 expression, upregulated Notch-1/Jagged-2 expression, and induced proliferation and differentiation disorders in ENPCs, which were reversed by the knockdown of Notch-1. Furthermore, overexpression of ZEB2 inhibited Notch-1/Jagged-2 signaling and ameliorated inflammation and dysfunction in LPS-induced ENPCs. Notch-1 overexpression enhanced LPS-induced dysfunction, but this effect was antagonized by the overexpression of ZEB2. CONCLUSION Overexpression of ZEB2 ameliorates LPS-induced ENPCs' dysfunction via the Notch-1/Jagged-2 pathway, thus playing a role in HAEC.

Abstract
The enteric nervous system (ENS) is an essential network of neurons and glia in the bowel wall. Defects in ENS development can result in Hirschsprung disease (HSCR), a life-threatening condition characterized by severe constipation, abdominal distention, bilious vomiting, and failure to thrive. A growing body of literature connects HSCR to alterations in miRNA expression, but there are limited data on the normal miRNA landscape in the developing ENS. We sequenced small RNAs (smRNA-seq) and messenger RNAs (mRNA-seq) from ENS precursor cells of mid-gestation Ednrb-EGFP mice and compared them to aggregated RNA from all other cells in the developing bowel. Our smRNA-seq results identified 73 miRNAs that were significantly enriched and highly expressed in the developing ENS, with miR-9, miR-27b, miR-124, miR-137, and miR-488 as our top 5 miRNAs that are conserved in humans. However, contrary to prior reports, our follow-up analyses of miR-137 showed that loss of Mir137 in Nestin-cre, Wnt1-cre, Sox10-cre, or Baf53b-cre lineage cells had no effect on mouse survival or ENS development. Our data provide important context for future studies of miRNAs in HSCR and other ENS diseases and highlight open questions about facility-specific factors in development.

Atractylodes lancea volatile oils target ADAR2-miR-181a-5p signaling to mesenchymal stem cell chondrogenic differentiation. Anat Rec (Hoboken) 2023; 306:3006-3020.

Abstract
Atractylodeslancea Rhizoma (Rhizoma atractylodis [RA]) has long been recommended for the treatment of arthritis in traditional Chinese medicine, but its mechanism of action is still unclear. RA contains a large amount of Atractylodes lancea volatile oils (Atr). In this study, we investigated whether Atr can promote mesenchymal stem cells (MSCs) chondrogenic differentiation. The Atr were extracted from RA by steam distillation method, and the effect of Atr on MSCs was detected by the CCK8 assay. The optimal concentration of Atr for MSCs cultivation was 3 μg/ml. The differentially expressed miR-181a-5p was screened by miRNA microarray assay, and its mimics and inhibitors were transfected into MSCs. It was found that the inhibitor of miR-181a-5p could upregulate cartilage-specific genes such as SOX9, COL2A1, and ACAN. Meanwhile, we also found that the expression of gene editing enzyme ADAR2 was significantly increased in the chondrogenic differentiation of MSCs induced by Atr, and the bases of precursor sequence of miR-181a-5p were changed from A to G. After ADAR2 deletion, the expression of cartilage-specific genes was significantly down-regulated and the precursor sequence bases of miR-181a-5p were not changed. Bioinformatics analysis revealed that the predicted target gene of miR-181a-5p was yingyang1 (YY1), and the targeting relationship was verified by dual-luciferase reporter assay. After deleting YY1, the expression of cartilage-specific genes was significantly down-regulated. In conclusion, our study demonstrated that Atr can promote chondrogenic differentiation of MSC through regulation of the ADAR2-miR-181a-5p signaling pathway. This may provide a new insight into the possible mechanism of traditional Chinese medicine (Atr) in treating inflammatory joint diseases.

Abstract
The SARS-CoV-2 pandemic was defined by the emergence of new variants formed through virus mutation originating from random errors not corrected by viral proofreading and/or the host antiviral response introducing mutations into the viral genome. While sequencing information hints at cellular RNA editing pathways playing a role in viral evolution, here, we use an in vitro human cell infection model to assess RNA mutation types in two SARS-CoV-2 strains representing the original and the alpha variants. The variants showed both different cellular responses and mutation patterns with alpha showing higher mutation frequency with most substitutions observed being C-U, indicating an important role for apolipoprotein B mRNA editing catalytic polypeptide-like editing. Knockdown of select APOBEC3s through RNAi increased virus production in the original virus, but not in alpha. Overall, these data suggest a deaminase-independent anti-viral function of APOBECs in SARS-CoV-2 while the C-U editing itself might function to enhance genetic diversity enabling evolutionary adaptation.

Abstract
Currently, more than 170 modifications have been identified on RNA. Among these RNA modifications, various methylations account for two-thirds of total cases and exist on almost all RNAs. Roles of RNA modifications in cancer are garnering increasing interest. The research on m6A RNA methylation in cancer is in full swing at present. However, there are still many other popular RNA modifications involved in the regulation of gene expression post-transcriptionally besides m6A RNA methylation. In this review, we focus on several important RNA modifications including m1A, m5C, m7G, 2'-O-Me, Ψ and A-to-I editing in cancer, which will provide a new perspective on tumourigenesis by peeking into the complex regulatory network of epigenetic RNA modifications, transcript processing, and protein translation.

Abstract
Circular RNAs (circRNAs) have been associated with lung cancer (LC), one of the most common cancers, but the underlying molecular mechanisms of the specific correlation with LC carcinogenesis remain unveiled. Quantitative real-time polymerase chain reaction was applied to examine the level of circZNF609. LC cells were transfected with silenced circZNF609 by siRNAs, and cell proliferation, migration, and apoptosis were evaluated to reflect the influences of circZNF609 knockdown in LC. Biotin-coupled circRNA capture, FISH and luciferase reporter assays were performed to study the relationship between circZNF609 and miR-142-3p. In current work, it was discovered that circZNF609 functioned as an onco-circRNA, which exhibited high expression as well as facilitated the proliferation and migration in LC cells. Next, we discovered that FUS RNA-binding protein, which could bind to the ZNF609 pre-mRNA, induced circZNF609 formation, and increased circZNF609 expression in LC. Furthermore, circZNF609 was verified to sponge and sequester miR-142-3p; circZNF609 enhanced LC cell proliferative and migrative ability via targeting miR-142-3p. Finally, G protein subunit beta 2 (GNB2) was figured out to involve in circZNF609/miR-142-3p axis-induced LC development. Conclusively, the results indicated that FUS-induced circZNF609 exerts promotional effects on LC cell proliferation and migration through modulation of the miR-142-3p/GNB2 axis, which could offer new insight for understanding LC.

Abstract
Non-small cell lung cancer (NSCLC) is prevalent worldwide. Lung squamous cell carcinoma (LUSC) is one of the main subtypes of NSCLC yet, currently, few biomarkers are available for the diagnosis of LUSC. The present study aimed to investigate the expression and role of adenosine deaminase RNA specific B1 (ADARB1) in lung squamous cell carcinoma (LUSC). Integrative bioinformatics analysis was used to identify the effects of ADARB1 expression on the occurrence and prognosis of LUSC. The expression of ADARB1 was further examined by immunohistochemistry (IHC). Bioinformatics analysis suggested that ADARB1 was downregulated in LUSC, serving as a potential tumor suppressor, and these results were verified by IHC performed on a lung cancer tissue array. Clinical studies suggested that ADARB1 expression and methylation levels were significantly associated with patient characteristics in LUSC. Moreover, ADARB1 global methylation levels were upregulated in LUSC tissues compared with normal lung tissues. Higher methylation levels of cg24063645 were associated with shorter overall survival time of patients with LUSC. A negative correlation was identified between ADARB1 and epidermal growth factor receptor (EGFR) expression in LUSC. Using the Gene Expression Omnibus database, it was suggested that the expression of ADARB1 in LUSC was significantly different compared with that in lung adenocarcinoma. Furthermore, protein-protein interactions were studied and a biological process annotation analysis was conducted. The present study suggested that ADARB1 was downregulated in LUSC; therefore, ADARB1 may serve as a specific biomarker and a potential therapeutic target for LUSC.

Abstract
Researches over the past decade suggest that lipopolysaccharide is a dominant driver of gastrointestinal motility and could damage the enteric neuron of rat or porcine. However, it remains poorly defined whether LPS participates in Hirschsprung's disease (HSCR). Here, we discovered that LPS increased in HSCR tissues. Furthermore, LPS treatment suppressed the proliferation and differentiation of neural precursor cells (NPCs) or proliferation and migration of human 293T cells. ADAR2 (adenosine deaminase acting on RNA2)‐mediated post‐transcriptional adenosine‐to‐inosine RNA editing promotes cancer progression. We show that increased LPS activates ADAR2 and subsequently regulates the A‐to‐I RNA editing which suppresses the miR‐142 expression. RNA sequencing combined with qRT‐PCR suggested that ADAR2 restrain cell migration and proliferation via pri‐miR‐142 editing and STAU1 up‐regulation. In conclusion, the findings illustrate that LPS participates in HSCR through the LPS‐ADAR2‐miR‐142‐STAU1 axis.
