Escaping but not the inactive X-linked protein complex coding genes may achieve X-chromosome dosage compensation and underlie X chromosome inactivation-related diseases. Heliyon 2023; 9:e17721. [PMID: 37449161 PMCID: PMC10336589 DOI: 10.1016/j.heliyon.2023.e17721] [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: 09/19/2022] [Revised: 06/05/2023] [Accepted: 06/26/2023] [Indexed: 07/18/2023] Open
Abstract
X chromosome dosage compensation (XDC) refers to the process by which X-linked genes acquire expression equivalence between two sexes. Ohno proposed that XDC is achieved by two-fold upregulations of X-linked genes in both sexes and by silencing one X chromosome (X chromosome inactivation, XCI) in females. However, genes subject to two-fold upregulations as well as the underlying mechanism remain unclear. It's reported that gene dosage changes may only affect X-linked dosage-sensitive genes, such as protein complex coding genes (PCGs). Our results showed that in human PCGs are more likely to escape XCI and escaping PCGs (EsP) show two-fold higher expression than inactivated PCGs (InP) or other X-linked genes at RNA and protein levels in both sexes, which suggest that EsP may achieve upregulations and XDC. The higher expressions of EsP possibly result from the upregulations of the single active X chromosome (Xa), rather than escaping expressions from the inactive X chromosome (Xi). EsP genes have relatively high expression levels in humans and lower dN/dS ratios, suggesting that they are likely under stronger selection pressure over evolutionary time. Our study also suggests that SP1 transcription factor is significantly enriched in EsP and may be involved in the up-regulations of EsP on the active X. Finally, human EsP genes in this study are enriched in the toll-like receptor pathway, NF-kB pathway, apoptotic pathway, and abnormal mental, developmental and reproductive phenotypes. These findings suggest misregulations of EsP may be involved in autoimmune, reproductive, and neurological diseases, providing insight for the diagnosis and treatment of these diseases.

Identification and differential expression of long non-coding RNAs and their association with XIST gene during early embryonic developmental stages of Bos taurus. Int J Biol Macromol 2023; 229:896-908.

Abstract
X-chromosomes inactivation (XCI) is a phenomenon that aims to equalize the dosage of X-linked gene products between XY males and XX females in mammals. XIST gene is the master regulator of X chromosome inactivation during early embryonic developmental stages of Bos taurus. Biological molecule such as lncRNA plays significant role in the control of XCI, by RNA-based regulatory mechanisms and are non-coding regions of the genome. In our study, using in-silico transcriptome data analysis approach, we analysed RNA-seq data of E35, E39 and E43 samples from bovine genital ridges of early embryonic stages, and identified lncRNA transcripts. More than 7 lakh lncRNA transcripts were identified. Further, our study identified DE-lncRNAs and genes between male and female and studied their co-expression. More than four thousand differentially expressed lncRNAs identified. The co-expression and RT-PCR study in the result showed that there exists an association between the XIST and DE-lncRNAs in early embryonic gonads of bovine at E35. In this study, the association between DE-lncRNAs and XIST gene indicates, the potentially important role of DE-lncRNAs during embryo development in bovine. In conclusion, this study shows there exist an interplay between genes and lncRNAs at transcriptome level of bovine during early embryonic days.

A de novo YY1 missense variant expanding the Gabriele-de Vries syndrome phenotype and affecting X-chromosome inactivation. Metab Brain Dis 2022; 37:2431-2440.

Abstract
Yin and Yang 1 gene (YY1; MIM#600,013) is recognized as a dual transcriptional activating and repressing factor, RNA-binding protein, and 3D chromatin regulator, with multi roles in neurodevelopmental and maintenance pathways. YY1 haploinsufficiency caused either by heterozygous sequence variants or deletions involving the whole gene has been recently associated with Gabriele-de Vries syndrome (GADEVS), a rare congenital autosomal dominant condition, leading to intellectual disability (ID) and multiple physical/behavioural abnormalities. Herein, we describe clinical and molecular findings from a Brazilian female harbouring a de novo missense pathogenic variant in YY1 gene (NM_003403.5:c.1106A > G; p.Asn369Ser) found by whole exome sequencing with potential implications for protein structure and function. Undescribed or uncommon clinical features in this patient included non-febrile seizures, severe scoliosis, hearing impairment, and chorioretinitis. Further bioinformatics analyses using YY1-other protein interaction networks reinforced the involvement of YY1 interactors in such phenotypes, in exception of chorioretinitis. Moreover, X-chromosome inactivation (XCI) skewing was evidenced in the patient and attributed to the haploinsufficiency of YY1, which direct and indirectly interacts with numerous XCI key regulators. Besides expanding the mutational and phenotype spectrum of GADEVS, our results highlight the role of YY1 as an essential autosomal regulator of XCI epigenetic process.
