Kozlowski P. Thirty Years with ERH: An mRNA Splicing and Mitosis Factor Only or Rather a Novel Genome Integrity Protector? Cells 2023; 12:2449. [PMID: 37887293 PMCID: PMC10605862 DOI: 10.3390/cells12202449] [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: 08/29/2023] [Revised: 10/10/2023] [Accepted: 10/12/2023] [Indexed: 10/28/2023] Open
Abstract
ERH is a 100 to about 110 aa nuclear protein with unique primary and three-dimensional structures that are very conserved from simple eukaryotes to humans, albeit some species have lost its gene, with most higher fungi being a noteworthy example. Initially, studies on Drosophila melanogaster implied its function in pyrimidine metabolism. Subsequently, research on Xenopus laevis suggested that it acts as a transcriptional repressor. Finally, studies in humans pointed to a role in pre-mRNA splicing and in mitosis but further research, also in Caenorhabditis elegans and Schizosaccharomyces pombe, demonstrated its much broader activity, namely involvement in the biogenesis of mRNA, and miRNA, piRNA and some other ncRNAs, and in repressive heterochromatin formation. ERH interacts with numerous, mostly taxon-specific proteins, like Mmi1 and Mei2 in S. pombe, PID-3/PICS-1, TOST-1 and PID-1 in C. elegans, and DGCR8, CIZ1, PDIP46/SKAR and SAFB1/2 in humans. There are, however, some common themes in this wide range of processes and partners, such as: (a) ERH homodimerizes to form a scaffold for several complexes involved in the metabolism of nucleic acids, (b) all these RNAs are RNA polymerase II transcripts, (c) pre-mRNAs, whose splicing depends on ERH, are enriched in transcripts of DNA damage response and DNA metabolism genes, and (d) heterochromatin is formed to silence unwanted transcription, e.g., from repetitive elements. Thus, it seems that ERH has been adopted for various pathways that serve to maintain genome integrity.

Chemerin-Induced Down-Regulation of Placenta-Derived Exosomal miR-140-3p and miR-574-3p Promotes Umbilical Vein Endothelial Cells Proliferation, Migration, and Tube Formation in Gestational Diabetes Mellitus. Cells 2022; 11:cells11213457. [PMID: 36359855 PMCID: PMC9655594 DOI: 10.3390/cells11213457] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2022] [Revised: 10/28/2022] [Accepted: 10/31/2022] [Indexed: 11/06/2022] Open
Abstract
Gestational diabetes mellitus (GDM) leads to poor pregnancy outcomes and fetoplacental endothelial dysfunction; however, the underlying mechanisms remain unknown. This study aimed to investigate the effect of placenta-derived exosomal miRNAs on fetoplacental endothelial dysfunction in GDM, as well as to further explore the role of chemerin to this end. Placenta-derived exosomal miR-140-3p and miR-574-3p expression (next-generation sequencing, quantitative real-time PCR), its interactions with cell function (Cell Counting Kit-8, Transwell, tube formation assay), chemerin interactions (Western blotting), and placental inflammation (immunofluorescence staining, enzyme-linked immunosorbent assay) were investigated. Placenta-derived exosomal miR-140-3p and miR-574-3p were downregulated in GDM. Additionally, miR-140-3p and miR-574-3p inhibited the proliferation, migration, and tube formation ability of umbilical vein endothelial cells by targeting vascular endothelial growth factor. Interestingly, miR-140-3p and miR-574-3p expression levels were negatively correlated with chemerin, which induced placental inflammation through the recruitment of macrophage cells and release of IL-18 and IL-1β. These findings indicate that chemerin reduces placenta-derived exosomal miR-140-3p and miR-574-3p levels by inducing placental inflammation, thereby promoting the proliferation, migration, and tube formation of umbilical vein endothelial cells in GDM, providing a novel perspective on the underlying pathogenesis and therapeutic targets for GDM and its offspring complications.

Abstract
Cancer is a major public health problem worldwide. Studies on oncogenes and tumor-targeted therapies have become an important part of cancer treatment development. In this review, we summarize and systematically introduce the gene enhancer of rudimentary homolog (ERH), which encodes a highly conserved small molecule protein. ERH mainly exists as a protein partner in human cells. It is involved in pyrimidine metabolism and protein complexes, acts as a transcriptional repressor, and participates in cell cycle regulation. Moreover, it is involved in DNA damage repair, mRNA splicing, the process of microRNA hairpins as well as erythroid differentiation. There are many related studies on the role of ERH in cancer cells; however, there are none on tumor-targeted therapeutic drugs or related therapies based on the expression of ERH. This study will provide possible directions for oncologists to further their research studies in this field.

A Multi-Omics Network of a Seven-Gene Prognostic Signature for Non-Small Cell Lung Cancer. Int J Mol Sci 2021; 23:ijms23010219. [PMID: 35008645 PMCID: PMC8745553 DOI: 10.3390/ijms23010219] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2021] [Revised: 12/22/2021] [Accepted: 12/23/2021] [Indexed: 12/30/2022] Open
Abstract
There is an unmet clinical need to identify patients with early-stage non-small cell lung cancer (NSCLC) who are likely to develop recurrence and to predict their therapeutic responses. Our previous study developed a qRT-PCR-based seven-gene microfluidic assay to predict the recurrence risk and the clinical benefits of chemotherapy. This study showed it was feasible to apply this seven-gene panel in RNA sequencing profiles of The Cancer Genome Atlas (TCGA) NSCLC patients (n = 923) in randomly partitioned feasibility-training and validation sets (p < 0.05, Kaplan-Meier analysis). Using Boolean implication networks, DNA copy number variation-mediated transcriptional regulatory network of the seven-gene signature was identified in multiple NSCLC cohorts (n = 371). The multi-omics network genes, including PD-L1, were significantly correlated with immune infiltration and drug response to 10 commonly used drugs for treating NSCLC. ZNF71 protein expression was positively correlated with epithelial markers and was negatively correlated with mesenchymal markers in NSCLC cell lines in Western blots. PI3K was identified as a relevant pathway of proliferation networks involving ZNF71 and its isoforms formulated with CRISPR-Cas9 and RNA interference (RNAi) profiles. Based on the gene expression of the multi-omics network, repositioning drugs were identified for NSCLC treatment.

Abstract
Aberrant expression of mitochondrial proteins impairs cardiac function and causes heart disease. The mechanism of regulation of mitochondria encoded protein expression during cardiac disease, however, remains underexplored. Here, we show that multiple pathogenic cardiac stressors induce the expression of miR-574 guide and passenger strands (miR-574-5p/3p) in both humans and mice. miR-574 knockout mice exhibit severe cardiac disorder under different pathogenic cardiac stresses while miR-574-5p/3p mimics that are delivered systematically using nanoparticles reduce cardiac pathogenesis under disease insults. Transcriptomic analysis of miR-574-null hearts uncovers family with sequence similarity 210 member A (FAM210A) as a common target mRNA of miR-574-5p and miR-574-3p. The interactome capture analysis suggests that FAM210A interacts with mitochondrial translation elongation factor EF-Tu. Manipulating miR-574-5p/3p or FAM210A expression changes the protein expression of mitochondrial-encoded electron transport chain (ETC) genes but not nuclear-encoded mitochondrial ETC genes in both human AC16 cardiomyocyte cells and miR-574-null murine hearts. Together, we discovered that miR-574 regulates FAM210A expression and modulates mitochondrial-encoded protein expression, which may influence cardiac remodeling in heart failure.

Abstract
Liver cancer is one of the most common and aggressive tumors, and usually leads to a poor clinical outcome. Increasing evidence has demonstrated the important functions of microRNAs (miRs) in tumor progression. miR-574-3p has been reported as a tumor suppressor and potential therapeutic target in various types of cancer. However, the underlying mechanism of the effects of miR-574-3p in liver cancer remains unknown. In the present study, reverse transcription-quantitative PCR was performed to detect miR-574-3p expression in liver cancer tissues, and the influence of miR-574-3p on cell growth was evaluated using the Cell Counting Kit-8 assay, and cell migration and flow cytometry analyses. The present study revealed that miR-574-3p expression was downregulated in liver cancer tissues and cell lines. miR-574-3p overexpression, achieved by transfecting miR-574-3p mimics into liver cancer cells, reduced cell proliferation and migration, and promoted cell apoptosis. Mechanistically, ADAM metallopeptidase domain 28 (ADAM28) was identified as a miR-574-3p target via binding to the 3'-untranslated region of the ADAM28 mRNA. Gain-of-function of miR-574-3p downregulated the expression levels of ADAM28 in liver cancer cells. Additionally, overexpression of ADAM28 significantly attenuated the suppressive effect of miR-574-3p on the growth of liver cancer cells. The present results provide novel insights into the function of the miR-574-3p/ADAM28 signaling pathway in liver cancer.

Knockdown of enhancer of rudimentary homolog inhibits proliferation and metastasis in ovarian cancer by regulating epithelial-mesenchymal transition. Biomed Pharmacother 2020; 125:109974.

Abstract
Ovarian cancer (OC) is the deadliest gynecological malignancy. The pathogenesis of molecular in epithelial ovarian cancer (EOC), main histological type of OC, has not been completely defined. Enhancer of rudimentary homolog (ERH) had been reported to participate in transcriptional regulation, mRNA splicing, DNA repair and DNA synthesis by binding a variety of proteins. In this study, immunohistochemical staining revealed that the protein expression of ERH was associated with histological type, lymph node metastasis and pathological grade in EOC patients. To verify the association of ERH with the prognosis of OC, a GSE microarray dataset was downloaded from the Gene Expression Omnibus (GEO) database. Survival analysis suggested that ERH may be associated with poor prognosis of OC. In addition, shRNA was used to knockdown the protein and mRNA expression levels of ERH in the OC cell line SKOV3. Inhibition of ERH expression slowed proliferation, promoted apoptosis and inhibited metastasis and invasion by regulating epithelial-mesenchymal transition (EMT) in SKOV3 cells. These results indicate that ERH protein promotes the development of OC and provides an experimental basis for ERH as the potential target for ovarian cancer treatment.

MiR-35 buffers apoptosis thresholds in the C. elegans germline by antagonizing both MAPK and core apoptosis pathways. Cell Death Differ 2019; 26:2637-2651.

Abstract
Apoptosis is a genetically programmed cell death process with profound roles in development and disease. MicroRNAs modulate the expression of many proteins and are often deregulated in human diseases, such as cancer. C. elegans germ cells undergo apoptosis in response to genotoxic stress by the combined activities of the core apoptosis and MAPK pathways, but how their signalling thresholds are buffered is an open question. Here we show mir-35–42 miRNA family play a dual role in antagonizing both NDK-1, a positive regulator of MAPK signalling, and the BH3-only pro-apoptotic protein EGL-1 to regulate the magnitude of DNA damage-induced apoptosis in the C. elegans germline. We show that while miR-35 represses EGL-1 by promoting transcript degradation, repression of NDK-1 may be through sequestration of the transcript to inhibit translation. Importantly, dramatic increase in NDK-1 expression was observed in cells about to die. In the absence of miR-35, increased NDK-1 activity enhanced MAPK signalling that lead to significant increases in germ cell death. Our findings demonstrate that NDK-1 acts upstream of (or in parallel to) EGL-1, and that miR-35 targets both egl-1 and ndk-1 to fine-tune cell killing in response to genotoxic stress.

Abstract
MicroRNA-574-3p (miR-574-3p) has different roles in different cancer types. However, the exact regulation mechanism of miR-574-3p in gastric cancer (GC) progression remains unclear. Thus, we aimed to evaluate the role of miR-574-3p in GC metastasis. We investigated the mechanism via which miR-574-3p regulated cancer cell migration and invasion to determine the relationship between epithelial mesenchymal transition (EMT) and drug resistance. Our results indicated that human GC cell line SGC7901 cells were more sensitive to cisplatin (DDP), but SGC7901 cisplatin-resistant cells (SGC7901/DDP) were more resistant to DDP and had mesenchymal characteristics. In addition, miR-574-3p overexpression up-regulated E-cadherin expression, and concomitantly down-regulated the expression of vimentin. We also identified zinc finger E-box binding homeobox transcription factor 1 (ZEB1), a crucial EMT inducer gene, as a new target of miR-574-3p. In fact, miR-574-3p bound the 3' untranslated region (3'-UTR) of ZEB1, regulating expression of this transcription factor at both the mRNA and protein levels. Furthermore, miR-574-3p overexpression reduced the migratory and invasive properties of the SGC7901/DDP cells and inhibited cisplatin (DDP) resistance in vitro and in vivo. In conclusion, the results indicated that miR-574-3p inhibited the EMT and enhanced cisplatin sensitivity in GC cells by suppressing ZEB1. These results provide further evidence for the critical roles of miR-574-3p and ZEB1 in invasion and migration regulation characteristics of GC cells.

Abstract
Background This study aimed to determine whether the enhancer of the rudimentary homolog (ERH) gene regulates cell migration and invasion in human bladder urothelial carcinoma (BUC) T24 cells and the underlying mechanism. Methods First, we knocked down ERH in BUC T24 and 5637 cells by shRNA and then used wound healing cell scratch migration assays, transwell cell migration assays, transwell cell invasion chamber experiments and nude mouse tail vein transfer assays to determine the migration and invasion ability after ERH was knocked down. Moreover, we used gene expression profiling chip analysis and further functional experiments to explore the possible mechanism through which ERH knockdown downregulated metastasis ability in T24 cells. Results Wound healing cell scratch migration assays, transwell cell migration assays, transwell cell invasion chamber experiments and nude mouse tail vein transfer assays all showed that the metastasis ability was significantly inhibited in human BUC T24 and 5637 cells with ERH knockdown. A gene expression profiling chip analysis in T24 cells showed that the MYC gene may be an important downstream target of the ERH gene, and the functional experiments showed that MYC is a functional target of ERH in BUC T24 cells. Conclusion ERH knockdown could inhibit the metastasis of BUC T24 cells in vitro and in vivo. This study further explored the mechanism of the ERH gene in the metastasis of the T24 human bladder cancer cell line and found that ERH may regulate MYC gene expression. The results of this research provide a basis for the clinical application of ERH as a potential target for BUC treatment.

Abstract
MicroRNAs (miRNAs) and heterogeneous nuclear ribonucleoproteins (hnRNPs) are families of sequence-specific, posttranscriptional modulators of gene expression. Despite extensive mechanistic and functional studies on both regulatory classes, the interactions and crosstalk between them are largely unexplored. We have reported that competition between miR-297 and hnRNP L to bind a 3΄UTR-localized CA-rich element (CARE) of VEGFA mRNA regulates its translation. Here, we show that translation of VEGFA mRNA in human myeloid cells is dictated by a bi-directional interaction between miR-574-3p, a CA-rich microRNA, and hnRNP L. In normoxia, miR-574-3p, acting as a decoy, binds cytoplasmic hnRNP L and prevents its binding to the CARE and stimulation of VEGFA mRNA translation, simultaneously permitting miR-297-mediated translational silencing. However, in hypoxia, cytoplasmic accumulation of Tyr359-phosphorylated hnRNP L sequesters miR-574-3p, overcoming its decoy activity and seed sequence-dependent gene silencing activity. Ectopically expressed miR-574-3p binds multiple RNA recognition motif (RRM) domains of hnRNP L, synergizes with miR-297, reduces VEGFA mRNA translation, and triggers apoptosis, thereby suppressing tumorigenesis. Our studies establish a novel condition-dependent interplay between a miRNA and an hnRNP that regulates their functions in a bidirectional manner.

Abstract
Intervertebral disc (IVD) degeneration (IDD) is the most common cause leading to low back pain (LBP), which is a highly prevalent, costly, and crippling condition worldwide. Current treatments for IDD are limited to treat the symptoms and do not target the pathophysiology. Tumor necrosis factor-α (TNF-α) is one of the most potent pro-inflammatory cytokines and signals through its receptors TNFR1 and TNFR2. TNF-α is highly expressed in degenerative IVD tissues, and it is deeply involved in multiple pathological processes of disc degeneration, including matrix destruction, inflammatory responses, apoptosis, autophagy, and cell proliferation. Importantly, anti-TNF-α therapy has shown promise for mitigating disc degeneration and relieving LBP. In this review, following a brief description of TNF-α signal transduction, we mainly focus on the expression pattern and roles of TNF-α in IDD, and summarize the emerging progress regarding its inhibition as a promising biological therapeutic approach to disc degeneration and associated LBP. A better understanding will help to develop novel TNF-α-centered therapeutic interventions for degenerative disc disease.

Abstract
The mechanisms that regulate miR-574-3p expression in cells remain elusive. In the present study, we used real-time PCR assay to demonstrate TGF-β1-induced miR-574-3p upregulation in AGS cells, which was inhibited by TGF-β receptor I inhibitor SB431542. We used a computer search to identify Smad binding sites upstream of the miR-574-3p precursor sequence. We demonstrated that silencing Smad4, but not Smad2 or Smad3, significantly inhibited the TGF-β1-induced miR-574-3p upregulation in AGS cells. Furthermore, TGF-β1 significantly increased the activity of a dual-luciferase reporter that contains the Smad binding sites upstream of the miR-574 precursor sequence. Silencing Smad4 significantly inhibited the TGF-β1-induced increase in the activity of the reporter in AGS cells. ChIP assay showed that Smad4 directly bound to the promoter of miR-574-3p. MiR-574-3p inhibition was effective in eliminating the inhibition of AGS cell proliferation induced by TGF-β1, suggesting that TGF-β1 inducing upregulation of miR-574-3p is functionally significant.

Abstract
Small molecule inhibitors of AKT (v-akt murine thymoma viral oncogene homolog) signaling are being evaluated in patients with various cancer types, but have so far proven therapeutically disappointing for reasons that remain unclear. Here, we treat cancer cells with subtherapeutic doses of Akti-1/2, an allosteric small molecule AKT inhibitor, in order to experimentally model pharmacologic inhibition of AKT signaling in vitro. We then apply a combined RNA, protein, and metabolite profiling approach to develop an integrated, multiscale, molecular snapshot of this "AKT(low)" cancer cell state. We find that AKT-inhibited cancer cells suppress thousands of mRNA transcripts, and proteins related to the cell cycle, ribosome, and protein translation. Surprisingly, however, these AKT-inhibited cells simultaneously upregulate a host of other proteins and metabolites posttranscriptionally, reflecting activation of their endo-vesiculo-membrane system, secretion of inflammatory proteins, and elaboration of extracellular microvesicles. Importantly, these microvesicles enable rapidly proliferating cancer cells of various types to better withstand different stress conditions, including serum deprivation, hypoxia, or cytotoxic chemotherapy in vitro and xenografting in vivo. These findings suggest a model whereby cancer cells experiencing a partial inhibition of AKT signaling may actually promote the survival of neighbors through non-cell autonomous communication.

Abstract
DNA methylation and miRNAs provide crucial regulation of the transcriptional and post-transcriptional responses to abiotic stress. In this study, we used methylation-sensitive amplification polymorphisms to identify 1066 sites that were differentially methylated in response to temperature stress in Populus simonii. Among these loci, BLAST searches of miRBase identified seven miRNA genes. Expression analysis by quantitative real-time PCR suggested that the methylation pattern of these miRNA genes probably influences their expression. Annotation of these miRNA genes in the sequenced genome of Populus trichocarpa found three target genes (Potri.007G090400, Potri.014G042200, and Potri.010G176000) for the miRNAs produced from five genes (Ptc-MIR396e and g, Ptc-MIR156i and j, and Ptc-MIR390c) respectively. The products of these target genes function in lipid metabolism to deplete lipid peroxide. We also constructed a network based on the interactions between DNA methylation and miRNAs, miRNAs and target genes, and the products of target genes and the metabolic factors that they affect, including H2O2, malondialdehyde, catalase (CAT), and superoxide dismutase. Our results suggested that DNA methylation probably regulates the expression of miRNA genes, thus affecting expression of their target genes, likely through the gene-silencing function of miRNAs, to maintain cell survival under abiotic stress conditions.

Abstract
Intervertebral disk degeneration (IDD) is the most common diagnosis in patients with low back pain, a main cause of musculoskeletal disability in the world. Interleukin-1 (IL-1) β is the most important member of the IL-1 family, and has a strong pro-inflammatory activity by stimulating the secretion of multiple pro-inflammatory mediators. IL-1β is highly expressed in degenerative intervertebral disk (IVD) tissues and cells, and it has been shown to be involved in multiple pathological processes during disk degeneration, including inflammatory responses, matrix destruction, angiogenesis and innervation, cellular apoptosis, oxidative stress and cellular senescence. However, inhibition of IL-1β is found to promote extracellular matrix (ECM) repair and protect against disk regeneration. In this review, after a brief description of IL-1β signaling, we mainly focus on the expression profiles, roles and therapeutic potential of IL-1β in IDD. A better understanding will help develop novel IL-1β-based therapeutic interventions for degenerative disk disease.

Abstract
Aetiology of intervertebral disc degeneration (IDD) is complex, with genetic, developmental, biochemical and biomechanical factors contributing to the disease process. It is becoming obvious that epigenetic processes influence evolution of IDD as strongly as the genetic background. Deregulated phenotypes of nucleus pulposus cells, including differentiation, migration, proliferation and apoptosis, are involved in all stages of progression of human IDD. Non-coding RNAs, including microRNAs, have recently been recognized as important regulators of gene expression. Research into roles of microRNAs in IDD has been very active over the past 5 years. Our review summarizes current research enlightenment towards understanding roles of microRNAs in regulating nucleus pulposus cell functions in IDD. These exciting findings support the notion that specific modulation of microRNAs may represent an attractive approach for management of IDD.

Abstract
The changes in cellular microRNA (miRNA) expression during the course of an adenovirus type 2 infection in human lung fibroblast were studied by deep RNA sequencing. Expressions of 175 miRNAs with over 100 transcripts per million nucleotides were changed more than 1.5-fold. The expression patterns of these miRNAs changed dramatically during the course of the infection, from upregulation of the miRNAs known as tumor suppressors (such as miR-22, miR-320, let-7, miR-181b, and miR-155) and down-regulation of oncogenic miRNAs (such as miR-21 and miR-31) early to downregulation of tumor suppressor miRNAs (such as let-7 family, mir-30 family, 23/27 cluster) and upregulation of oncogenic miRNAs (include miR-125, miR-27, miR-191) late after infection. The switch in miRNA expression pattern occurred when adenovirus DNA replication started. Furthermore, deregulation of cellular miRNA expression was a step-wise and special sets of miRNAs were deregulated in different phases of infection.
