Paediatrics congenital heart disease is associated with plasma miRNAs. Pediatr Res 2024:10.1038/s41390-024-03230-3. [PMID: 38755412 DOI: 10.1038/s41390-024-03230-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2023] [Revised: 04/02/2024] [Accepted: 04/07/2024] [Indexed: 05/18/2024]
Abstract
BACKGROUND Congenital heart disease (CHD) are the most common malformations from birth. The severity of the different forms of CHD varies extensively from superficial mild lesions with follow-up for decades without any treatment to complex cyanotic malformations requiring urgent surgical intervention. microRNAs have been found to be crucial in cardiac development, giving rise to possible phenotypes in CHD. OBJECTIVES We aimed to evaluate the expression of miRNAs in 86 children with CHD and divided into cyanotic and non-cyanotic heart defects and 110 controls. METHODS The miRNAs expression of miR-21-5p, miR-155-5p, miR-221-3p, miR-26a-5p, and miR-144-3p were analyzed by RT-qPCR. In addition, the expressions of the miRNAs studied were correlated with the clinical characteristics of both the children and the mothers. RESULTS The expression levels of miR-21-5-5p, miR-15-5p5, miR-221-3p, and miR-26-5p significantly differed between CHD and control subjects. Moreover, miR-21-5p levels were higher in patients with cyanotic versus non-cyanotic CHD patients. CONCLUSION The expression levels of miRNAs of pediatric patients with CHD could participating in the development of cardiac malformations. Additionally, the high expression of miR-21-5p in cyanotic CHD children may be related to greater severity of illness relative to non-cyanotic CHD. IMPACT This study adds to knowledge of the association between microRNAs and congenital heart disease in children. The expression levels of miR-21-5-5p, miR-15-5p5, miR-221-3p, and miR-26-5p of pediatric patients with CHD could be involved in the development and phenotype present in pediatric patients. miR-21-5p may help to discriminate between cyanotic and non-cyanotic CHD. In the future, the miRNAs studied could have applications as clinical biomarkers.

Suo MJ, Chen WC, Xu ZQ, Tian GX, Li T, Li P, Sheng W, Huang GY, Ma XJ. X-linked BCOR variants identified in Chinese Han patients with congenital heart disease. J Gene Med 2023; 25:e3461. [PMID: 36314054 DOI: 10.1002/jgm.3461] [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: 08/15/2022] [Revised: 10/08/2022] [Accepted: 10/20/2022] [Indexed: 11/05/2022] Open
Abstract
BACKGROUND Congenital heart disease (CHD) frequently manifests as a complex phenotype and approximately one-third of cases may be caused by genetic factors. BCOR, an X-linked gene encoding the corepressor of BCL6, has been demonstrated to be closely involved in human heart development. However, whether BCOR variants represent the genetic etiology underlying CHD needs further investigation. METHODS We performed whole exome sequencing on CHD nuclear families and identified a candidate gene, BCOR, by robust bioinformatic analysis and medical literature searches. Targeted DNA sequencing of the candidate gene was conducted and then the association between variants and the risk of developing CHD was analyzed. The effects of BCOR mutations on gene expression, localization, protein interaction, and signaling pathways were evaluated in vitro. RESULTS We identified a BCOR hemizygous missense variant (c.1448C>T, p.Pro483Leu) in a male proband presented with CHD/heterotaxy. Sanger sequencing confirmed that this variant was inherited from his asymptomatic mother. Interestingly, through literature searches, we observed another novel BCOR hemizygous missense variant (c.1619G>A, p.Arg540Gln) in a CHD patient with heterotaxy, supporting the pathogenic evidence of BCOR variants. Functional experiments conducted in vitro revealed that the variant p.Pro483Leu altered the subcellular localization of BCOR protein, disrupted its interaction with BCL6, and significantly promoted cell proliferation, whereas the variant p.Arg540Gln displayed no obvious effects. Nevertheless, transcriptional analysis revealed that down-regulation of BCOR substantially enhanced the activities of mitogen-activated protein and phosphoinositide 3-kinase-AKT signaling pathways, which are closely attributed to heart development. Targeted sequencing of 932 sporadic CHD patients enriched nine variants of BCOR predicted as likely rare and damaging and a septal defect was present in 81.8% (9/11) of them, including the two probands, which was consistent with the possible phenotype caused by BCOR defects. CONCLUSIONS The findings of the present study indicate that variants in BCOR may predispose individuals to CHD in the Chinese Han population.

Mechanism of Danhong Injection in the Treatment of Arrhythmia Based on Network Pharmacology, Molecular Docking, and In Vitro Experiments. BIOMED RESEARCH INTERNATIONAL 2022; 2022:4336870. [PMID: 35915792 PMCID: PMC9338864 DOI: 10.1155/2022/4336870] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Revised: 07/02/2022] [Accepted: 07/06/2022] [Indexed: 11/18/2022]
Abstract
Background. Danhong injection (DHI) is widely used in the treatment of cardiovascular and cerebrovascular diseases, and its safety and effectiveness have been widely recognized and applied in China. However, the potential molecular mechanism of action for the treatment of arrhythmia is not fully understood. Aim. In this study, through network pharmacology and in vitro cell experiments, we explored the active compounds of DHI for the treatment of arrhythmia and predicted the potential targets of the drug to investigate its mechanism of action. Materials and Methods. First, the potential therapeutic effect of DHI on arrhythmia was investigated in an in vitro arrhythmia model using human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs), in which calcium transients were recorded to evaluate the status of arrhythmia. Next, the active compounds and key targets in the treatment of arrhythmia were identified through network pharmacology and molecular docking, and the key signaling pathways related to the treatment of arrhythmia were analyzed. Furthermore, we used real-time quantitative reverse transcription PCR (qRT–PCR) to verify the expression levels of key genes. Results. Early afterdepolarizations (EADs) were observed during aconitine treatment in hiPSC-CMs, and the proarrhythmic effect of aconitine was partially rescued by DHI, indicating that the antiarrhythmic role of DHI was verified in an in vitro human cardiomyocyte model. To further dissect the underlying molecular basis of this observation, network pharmacology analysis was performed, and the results showed that there were 108 crosstargets between DHI and arrhythmia. Moreover, 30 of these targets, such as AKT1 and HMOX1, were key genes. In addition, the mRNA expression of AKT1 and HMOX1 could be regulated by DHI. Conclusion. DHI can alleviate aconitine-induced arrhythmia in an in vitro model, presumably because of its multitarget regulatory mechanism. Key genes, such as AKT1 and HMOX1, may contribute to the antiarrhythmic role of DHI in the heart.

Abstract
The article is devoted to the mechanisms of regulation of redox processes in cells, a review of the Keap1 / Nrf2 / ARE redox-sensitive signaling system as a fundamental pathway that plays a key role in maintaining cellular redox homeostasis under stressful, inflammatory, carcinogenic and proapoptotic conditions. The structure of the cysteine-rich repressor protein Keap1, which is responsible for sensory perception of electrophiles and reactive oxygen species, the structure and functions of the transcription factor Nrf2, mechanisms of Nrf2 activation through the Keap1 / Nrf2 / ARE signaling system, which regulates the transcription and expression of cellular cytoprotective and antioxidant proteins, are described. Published data on the specificity of the interaction of the components of this cellular signaling pathway, the mechanisms of Keap1 dependent and independent adaptive response to the action of inductors, the role of biogenic selenium nanoparticles synthesized by green chemistry with the participation of bacteria in these processes are analyzed; features of Nrf2 induction depending on the type of bacteria and the stabilizing shell. It has been shown that biogenic selenium nanoparticles (BNSe), synthesized by different types of bacteria, activate the transcription factor Nrf2 using the Keap1-independent activation pathway through mitogen-protein kinases (MAPK): p38, ERK1 / 2 and AKT-mediated phosphorylation of Nrf2, protect the intestinal epithelial barrier function from the effects of oxidative damage, normalize mitochondrial function. A detailed understanding of thiol-dependent and independent redox signaling mechanisms under physiological and pathological conditions will lead to a deeper understanding of the redox component in human and animal diseases. The use of biogenic nanoselen, synthesized with the participation of various bacterial species, has been demonstrated to activate the Keap1 / Nrf2 / ARE signaling pathway, which may be of practical interest as a therapeutic target for many redox-mediated diseases.
