Single nucleotide polymorphisms of PCP pathway related genes participate in the occurrence and development of neural tube defect. Mol Genet Genomic Med 2022; 11:e2094. [PMID: 36378568 PMCID: PMC9834144 DOI: 10.1002/mgg3.2094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 10/08/2022] [Accepted: 10/27/2022] [Indexed: 11/17/2022] Open
Abstract
BACKGROUND To screen the single nucleotide polymorphisms (SNPs) in the coding regions of VANGL and FZD family members related to the plane cell polarity (PCP) signaling pathway in neural tube defects (NTDs) patients, so as to provide theoretical and experimental basis for the prevention and treatment of NTDs by intervening PCP signal transduction. METHODS 112 NTDs patients were collected as the case group and 112 craniocerebral trauma patients as control. Afterwards, blood genomic DNA was extracted and sequenced. The distribution of SNP alleles and genotypes between case and control groups was analyzed. Finally, the NTD rat model was constructed, and the effect of SNPs on the expression level of VANGL and FZD genes was verified by qRT-PCR. RESULTS GC genotype was newly found at VANGL1 c.346G>A, as well as AT genotype in FZD6 c.97A>G. The distribution of VANGL1 c.346g>A allele and genotype was statistically different between the case and control groups (p < 0.05). The newly found genotype GC increased the risk of NTDs (OR = 9.918, 95% CI: 1.234%-79.709%). The results of qRT-PCR showed that the expression level of FZD6 in E11 NTD fetuses were significantly increased (p < 0.05), but there was no obvious difference in the expression of VANGL1. CONCLUSION We found a new variant of VANGL1 c.346G>A, whose GC genotype might play an important role in the pathogenesis of NTDs. The SNPs of VANGL1 had no significant effect on its expression level, indicating that it may induce NTDs through other ways. FZD6 was significantly overexpressed in NTDs fetuses.

Anti-tuberculosis drugs used in a directly observed treatment short course (DOTS) schedule alter endocrine patterns and reduce the ovarian reserve and oocyte quality in the mouse. Reprod Fertil Dev 2022; 34:1059-1077.

Abstract
CONTEXT Tuberculosis is one of the major infectious diseases, with people of reproductive age group having a high risk of infection. AIMS The present study was designed to understand the consequences of anti-tuberculosis drugs (ATDs) used in DOTS (directly observed treatment short course) schedule on ovarian function. METHODS Adult female Swiss albino mice were orally administered with combinations of ATDs used in the DOTS schedule every day for 4weeks. At 2weeks after the cessation of ATDs administration, the endocrine changes and ovarian function were assessed in mice. KEY RESULTS Administration of ATDs to mice resulted in a prolonged estrous cycle, reduced ovarian follicle reserve, alteration in FSH, LH, and progesterone level, and decreased the number of ovulated oocytes. Further, the degree of fragmentation, degeneration, abnormal distribution of cytoplasmic organelles, abnormal spindle organisation, and chromosomal misalignment were higher in oocytes that were ovulated following superovulation. Blastocysts derived from ATDs treated mice had significantly lower total cell numbers and greater DNA damage. A marginal increase in the number of resorbed fetuses was observed in all the ATDs treated groups except in the multidrug resistance treatment group. Male progeny of ATDs treated mice had decreased sperm count and lower progressive motility, while female progeny exhibited a non-significant reduction in the number of oocytes ovulated. CONCLUSIONS Theresults of this study suggest that ATDs can have significant adverse effects on the ovarian reserve, cytoplasmic organisation of oocytes, and can potentially cause transgenerational changes. IMPLICATIONS The findings of the present study indicate ovarian toxicity of ATDs and warrant further research in the direction of identifying alternate drugs with minimal toxicity, and strategies to mitigate the ovarian toxicity induced by these drugs.

Abstract
Background The epidemiology of neural tube defect (NTD) is face ignorance from the global community. However, the problem is complex and it is a cause for child mortality and morbidity. We provide the latest insights with respect to determinant factors of NTD. Methods Google Scholar and PubMed were systematically searched to identify potential research articles concerning the epidemiology and its determinant factors of NTD. Results The epidemiology of Neural tube defects increased in some countries. The epidemiology and determinant factors were varies across countries,geographical regions and socioeconomic status of the populations. In general, the determinant factors of NTD were summarized as behavioral, nutrition-related, environmental, medical illness, and health service-related factors. Conclusion Birth defect is fatal which affects the new generation; specifically, NTD is the problem of middle- and low-income countries. It is a direct cause for neonatal and perinatal mortality rate globally. Even if little factors identified, yet conducting experimental and clinical trial researches are a better approach to slow down the progress.
