Front Endocrinol (Lausanne) 2023; 14:1205408. [PMID: 37720526 PMCID: PMC10499623 DOI: 10.3389/fendo.2023.1205408] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Accepted: 08/15/2023] [Indexed: 09/19/2023] Open
Abstract
The maternal-fetal interface is defined as the interface between maternal tissue and sections of the fetus in close contact. RNA methylation modifications are the most frequent kind of RNA alterations. It is effective throughout both normal and pathological implantation and placentation during pregnancy. By influencing early embryo development, embryo implantation, endometrium receptivity, immune microenvironment, as well as some implantation and placentation-related disorders like miscarriage and preeclampsia, it is essential for the establishment of the maternal-fetal interface. Our review focuses on the role of dynamic RNA methylation at the maternal-fetal interface, which has received little attention thus far. It has given the mechanistic underpinnings for both normal and abnormal implantation and placentation and could eventually provide an entirely novel approach to treating related complications.

Cell Death Dis 2023; 14:344. [PMID: 37253771 DOI: 10.1038/s41419-023-05852-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/18/2022] [Revised: 04/11/2023] [Accepted: 05/05/2023] [Indexed: 06/01/2023]
Abstract
Cardiac hypertrophy is a common structural remodeling in many cardiovascular diseases. Recently, long non-coding RNAs (LncRNAs) were found to be involved in the physiological and pathological processes of cardiac hypertrophy. In this study, we found that LncRNA KCND1 (LncKCND1) was downregulated in both transverse aortic constriction (TAC)-induced hypertrophic mouse hearts and Angiotensin II (Ang II)-induced neonatal mouse cardiomyocytes. Further analyses showed that the knockdown of LncKCND1 impaired cardiac mitochondrial function and led to hypertrophic changes in cardiomyocytes. In contrast, overexpression of LncKCND1 inhibited Ang II-induced cardiomyocyte hypertrophic changes. Importantly, enhanced expression of LncKCND1 protected the heart from TAC-induced pathological cardiac hypertrophy and improved heart function in TAC mice. Subsequent analyses involving mass spectrometry and RNA immunoprecipitation assays showed that LncKCND1 directly binds to YBX1. Furthermore, overexpression of LncKCND1 upregulated the expression level of YBX1, while silencing LncKCND1 had the opposite effect. Furthermore, YBX1 was downregulated during cardiac hypertrophy, whereas overexpression of YBX1 inhibited Ang II-induced cardiomyocyte hypertrophy. Moreover, silencing YBX1 reversed the effect of LncKCND1 on cardiomyocyte mitochondrial function and its protective role in cardiac hypertrophy, suggesting that YBX1 is a downstream target of LncKCND1 in regulating cardiac hypertrophy. In conclusion, our study provides mechanistic insights into the functioning of LncKCND1 and supports LncKCND1 as a potential therapeutic target for pathological cardiac hypertrophy.

Abstract
MOTIVATION The RNA splicing efficiency is of high interest for both understanding the regulatory machinery of gene expression and estimating the RNA velocity in single cells. However, its genomic regulation and stochasticity across contexts remain poorly understood. RESULTS Here, by leveraging the recent RNA velocity tool, we estimated the relative splicing efficiency across a variety of single-cell RNA-Seq data sets. We further extracted large sets of genomic features and 120 RNA binding protein features and found they are highly predictive to relative RNA splicing efficiency across multiple tissues and organs on human and mouse. This predictive power brings promise to reveal the complexity of RNA processing and to enhance the analysis of single-cell transcription activities. AVAILABILITY AND IMPLEMENTATION In order to ensure reproducibility, all preprocessed data sets and scripts used for the prediction and figure generation are publicly available at https://doi.org/10.5281/zenodo.6513669. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

Abstract
1. The DNA/RNA binding protein YBX3 is associated with gene transcription, DNA repair, and the progression of various diseases and is highly conserved from bacteria to humans.2. The following experiment found a 27-bp insertion/deletion polymorphism in the intron region of the YBX3 gene through resequencing. In cross-designed, F2 resource groups, the indel was significantly associated with broiler weight and body size at 0, 2, 4, 6, 8, 10 and 12 weeks of age and several other traits (semi evisceration weight (SEW), evisceration weight (EW), semi evisceration rate (SER), evisceration rate (ER), head weight (HW), claw weight (CLW), wing weight (DWW), gizzard weight (GW), pancreas weight (PW), chest muscle weight (CMW), leg weight (LW), leg muscle weight (LMW), shedding weight (SW), carcass weight (CW) and pectoral area (PA)) (P<0.05).3. The insertion-insertion (II) genotype was significantly associated with the greatest growth traits and carcass traits, whereas the values associated with the insertion-deletion (ID) genotype were the lowest in the F2 reciprocal cross chickens.4. The mutation sites were genotyped in 3611 individuals from 13 different chicken breeds and cross-designed F2 resource groups. The II genotype is the most important in commercial broilers, and the I allele frequency observed in these breeds was relatively high. However, there is still considerable potential in breeding dual-purpose chickens and commercial laying hens.5. The mRNA expression of the YBX3 gene in tissues from different breeds and developmental stages demonstrated that the 27-bp indel may affect the entire development process of poultry by affecting muscle development. These findings are beneficial for elucidating the function of the YBX3 gene and facilitating enhanced reproduction in the chicken industry.

Abstract
Mutations in human mitochondrial tRNAs (mt-tRNAs) are responsible for several and sometimes severe clinical phenotypes, classified among mitochondrial diseases. In addition, post-transcriptional modifications of mt-tRNAs in correlation with several stress signals can affect their stability similarly to what has been described for their nuclear-encoded counterparts. Many of the perturbations related to either point mutations or aberrant modifications of mt-tRNAs can lead to specific cleavage and the production of mitochondrial tRNA-derived fragments (mt-tRFs). Although mt-tRFs have been detected in several studies, the exact biogenesis steps and biological role remain, to a great extent, unexplored. Several mt-tRFs are produced because of the excessive oxidative stress which predominantly affects mitochondrial DNA integrity. In addition, mt-tRFs have been detected in various diseases with possible detrimental consequences, but also their production may represent a response mechanism to external stimuli, including infections from pathogens. Finally, specific point mutations on mt-tRNAs have been reported to impact the pool of the produced mt-tRFs and there is growing evidence suggesting that mt-tRFs can be exported and act in the cytoplasm. In this review, we summarize current knowledge on mitochondrial tRNA-deriving fragments and their possible contribution to gene expression regulation.

Abstract
Spinal muscular atrophy (SMA) is an autosomal recessive motor neuron disease of variable clinical severity that is caused by mutations in the survival motor neuron 1 (SMN1) gene. Despite its name, SMN is a ubiquitous protein that functions within and outside the nervous system and has multiple cellular roles in transcription, translation, and proteostatic mechanisms. Encouragingly, several SMN-directed therapies have recently reached the clinic, albeit this has highlighted the increasing need to develop combinatorial therapies for SMA to achieve full clinical efficacy. As a subcellular site of dysfunction in SMA, mitochondria represents a relevant target for a combinatorial therapy. Accordingly, we will discuss our current understanding of mitochondrial dysfunction in SMA, highlighting mitochondrial-based pathways that offer further mechanistic insights into the involvement of mitochondria in SMA. This may ultimately facilitate translational development of targeted mitochondrial therapies for SMA. Due to clinical and mechanistic overlaps, such strategies may also benefit other motor neuron diseases and related neurodegenerative disorders.

Abstract
Mitochondrial-derived peptides (MDPs) are a novel class of bioactive microproteins that modify cell metabolism. The the eight MDPs that been characterized (e.g., humanin, MOTS-c, SHLPs1-6) attenuate disease pathology including Alzheimer's disease, prostate cancer, macular degeneration, cardiovascular disease, and diabetes. The association between disease and human genetic variation in MDPs is underexplored, although two polymorphisms in humanin and MOTS-c associate with cognitive decline and diabetes, respectively, suggesting a precise role for MDPs in disease-modification. There could be hundreds of additional MDPs that have yet to be discovered. Altogether, MDPs could explain unanswered biological and metabolic questions and are part of a growing field of novel microproteins encoded by small open reading frames. In this review, the current state of MDPs are summarized with an emphasis on biological and therapeutic implications.

Abstract
Y-box binding proteins (YB proteins) are DNA/RNA-binding proteins belonging to a large family of proteins with the cold shock domain. Functionally, these proteins are known to be the most diverse, although the literature hardly offers any molecular mechanisms governing their activities in the cell, tissue, or the whole organism. This review describes the involvement of YB proteins in RNA-dependent processes, such as mRNA packaging into mRNPs, mRNA translation, and mRNA stabilization. In addition, recent data on the structural peculiarities of YB proteins underlying their interactions with nucleic acids are discussed.

Abstract
The frequency of dermatological manifestations in diseases due to mitochondrial DNA mutations is not well known, although multiple symmetric lipomatosis has been repeatedly associated to mitochondrial DNA mutations. Here, we present a patient suffering from multiple symmetric lipomatosis and other skin signs. We found a new mitochondrial DNA mutation, m.8357T>C, in the tRNALys -coding gene and, using a cybrid approach, confirmed its pathogenicity. A meta-analysis of the dermatological signs of the patient shows that they are not common in patients with confirmed mitochondrial DNA mutations and suggests that, in these cases, lipomatosis is not related to the oxidative phosphorylation dysfunction, but to an alteration of an additional function associated to particular mitochondrial tRNAs.

Abstract
Autophagy is an important metabolic pathway of cells. Cells degrade harmful intracellular components with the aid of autophagy to maintain a healthy state. In recent decades, the study of non-coding RNA in the regulation of autophagy has been a hot area. Mounting evidence indicates that many ncRNAs are involved in the dynamic process of autophagy, and further studies were undertaken to dissect the detailed cellular and molecular mechanisms underlying this process. In this chapter, we mainly summarized the regulation of different non-coding RNAs in autophagy as well as the detailed mechanisms. Based on these findings, we also discussed the roles of non-coding RNAs in the diagnosis, treatment, and prognosis of diseases with an emphasis on their use as potential biomarkers and therapeutic targets for different diseases.
