BMC Genom Data 2023; 24:77. [PMID: 38097986 PMCID: PMC10720224 DOI: 10.1186/s12863-023-01182-x] [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] [Subscribe] [Scholar Register] [Received: 02/04/2023] [Accepted: 12/08/2023] [Indexed: 12/17/2023] Open
Abstract
BACKGROUND Goat products have played a crucial role in meeting the dietary demands of people since the Neolithic era, giving rise to a multitude of goat breeds globally with varying characteristics and meat qualities. The primary objective of this study is to pinpoint the pivotal genes and their functions responsible for regulating muscle fiber growth in the longissimus dorsi muscle (LDM) through DNA methylation modifications in Hainan black goats and hybrid goats. METHODS Whole-genome bisulfite sequencing (WGBS) was employed to scrutinize the impact of methylation on LDM growth. This was accomplished by comparing methylation differences, gene expression, and their associations with growth-related traits. RESULTS In this study, we identified a total of 3,269 genes from differentially methylated regions (DMR), and detected 189 differentially expressed genes (DEGs) through RNA-seq analysis. Hypo DMR genes were primarily enriched in KEGG terms associated with muscle development, such as MAPK and PI3K-Akt signaling pathways. We selected 11 hub genes from the network that intersected the gene sets within DMR and DEGs, and nine genes exhibited significant correlation with one or more of the three LDM growth traits, namely area, height, and weight of loin eye muscle. Particularly, PRKG1 demonstrated a negative correlation with all three traits. The top five most crucial genes played vital roles in muscle fiber growth: FOXO3 safeguarded the myofiber's immune environment, FOXO6 was involved in myotube development and differentiation, and PRKG1 facilitated vasodilatation to release more glucose. This, in turn, accelerated the transfer of glucose from blood vessels to myofibers, regulated by ADCY5 and AKT2, ultimately ensuring glycogen storage and energy provision in muscle fibers. CONCLUSION This study delved into the diverse methylation modifications affecting critical genes, which collectively contribute to the maintenance of glycogen storage around myofibers, ultimately supporting muscle fiber growth.

Abstract
Meat tenderness is an important sensory index when consumers choose meat products, which determines the value of meat products and consumers' buying intentions. Yak meat is rich in nutrition and unique in flavor, which is favored by consumers. However, its meat has the deficiencies of low tenderness and poor taste, which has a negative impact on the value of its meat products and customer satisfaction. To identify the genes affecting the yak meat tenderness, we used RNA-seq to analyze the longissimus dorsi muscle of yaks with different tenderness, screened a total of 1120 differentially expressed genes (DEGs). Meanwhile, 23 pathways were significantly enriched. By further analysis, we identified eight genes related to yak meat tenderness (WNT5A, ARID5B, SERPINE1 KLHL40, RUNX1, MAFF, RFX7 and ARID5A). Notably, SERPINE1 was involved in the significant enrichment pathways of 'complement and coagulation cascade pathway', 'HIF-1 signaling pathway' and 'AGE-RAGE signaling pathway in diabetic complications' which can regulate meat tenderness. This implies that SERPINE1 may play an important regulatory role among them. The DEGs associated with yak meat quality screened in this work will be helpful to identify potential biomarkers related to meat tenderness.

Abstract
BACKGROUND RUNX1 is a transcription factor and a master regulator for the specification of the hematopoietic lineage during embryogenesis and postnatal megakaryopoiesis. Mutations and rearrangements on RUNX1 are key drivers of hematological malignancies. In humans, this gene is localized to the 'Down syndrome critical region' of chromosome 21, triplication of which is necessary and sufficient for most phenotypes that characterize Trisomy 21. MAIN BODY Individuals with Down syndrome show a higher predisposition to leukemias. Hence, RUNX1 overexpression was initially proposed as a critical player on Down syndrome-associated leukemogenesis. Less is known about the functions of RUNX1 in other tissues and organs, although growing reports show important implications in development or homeostasis of neural tissues, muscle, heart, bone, ovary, or the endothelium, among others. Even less is understood about the consequences on these tissues of RUNX1 gene dosage alterations in the context of Down syndrome. In this review, we summarize the current knowledge on RUNX1 activities outside blood/leukemia, while suggesting for the first time their potential relation to specific Trisomy 21 co-occurring conditions. CONCLUSION Our concise review on the emerging RUNX1 roles in different tissues outside the hematopoietic context provides a number of well-funded hypotheses that will open new research avenues toward a better understanding of RUNX1-mediated transcription in health and disease, contributing to novel potential diagnostic and therapeutic strategies for Down syndrome-associated conditions.

The Novel Structural Variation in the GHR Gene Is Associated with Growth Traits in Yaks ( Bos grunniens). Animals (Basel) 2023; 13:ani13050851.

Abstract
The growth hormone receptor (GHR) is a member of the cytokine/hematopoietic factor receptor superfamily, which plays an important role in the growth and development, immunity, and metabolism of animals. This study identified a 246 bp deletion variant in the intronic region of the GHR gene, and three genotypes, including type II, type ID, and type DD, were observed. Genotype analysis of structural variation (SV) was performed on 585 individuals from 14 yak breeds, and it was found that 246 bp deletion was present in each breed. The II genotype was dominant in all yak breeds except for SB yak. The association analysis of gene polymorphisms and growth traits in the ASD yak population showed that the 246 bp SV was significantly associated with body length at 6 months (p < 0.05). GHR messenger RNA (mRNA) was expressed in all the tested tissues, with significantly higher levels in the liver, muscle, and fat than in other organs. The results of transcription activity showed that the luciferase activity of the pGL4.10-DD vector was significantly higher than that of the pGL4.10-II vector (p < 0.05). Additionally, the transcription-factor binding prediction results showed that the SV in the runt-related transcription factor 1 (Runx1) transcription-factor binding site may affect the transcriptional activity of the GHR gene, regulating yak growth and development. This study showed that the novel SV of the GHR gene could be used as a candidate molecular marker for the selection of the early growth trait in ASD yak.

Abstract
Phosphodiesterase 5A (PDE5A) is involved in cGMP hydrolysis, regulating many physiological processes. Increased activity of PDE5A has been found in several pathological conditions, and the pharmacological inhibition of PDE5 has been demonstrated to have several therapeutic applications. We have identified the presence of three different Pde5a isoforms in cardiomyocytes, and we have found that the expression of specific Pde5a isoforms may have a causal role in the onset of pathological responses in these cells. In our previous study, we demonstrated that PDE5A inhibition could ameliorate muscular dystrophy by acting at different levels, as assessed by the altered genomic response of muscular cells following treatment with the PDE5A inhibitor tadalafil. Thus, considering the importance of PDE5A in various pathophysiological conditions, we further investigated the regulation of this enzyme. Here, we analysed the expression of Pde5a isoforms in the pathophysiology of skeletal muscle. We found that skeletal muscle tissues and myogenic cells express Pde5a1 and Pde5a2 isoforms, and we observed an increased expression of Pde5a1 in damaged skeletal muscles, while Pde5a2 levels remained unchanged. We also cloned and characterized the promoters that control the transcription of Pde5a isoforms, investigating which of the transcription factors predicted by bioinformatics analysis could be involved in their modulation. In conclusion, we found an overexpression of Pde5a1 in compromised muscle and identified an involvement of MyoD and Runx1 in Pde5a1 transcriptional activity.

Abstract
Runt-related transcription factor-1 (Runx1) is well known for its functions in hematopoiesis and leukemia but recent research has focused on its role in skeletal development and osteoarthritis (OA). Deficiency of the Runx1 gene is fatal in early embryonic development, and specific knockout of Runx1 in cell lineages of cartilage and bone leads to delayed cartilage formation and impaired bone calcification. Runx1 can regulate genes including collagen type II (Col2a1) and X (Col10a1), SRY-box transcription factor 9 (Sox9), aggrecan (Acan) and matrix metalloproteinase 13 (MMP-13), and the up-regulation of Runx1 improves the homeostasis of the whole joint, even in the pathological state. Moreover, Runx1 is activated as a response to mechanical compression, but impaired in the joint with the pathological progress associated with osteoarthritis. Therefore, interpretation about the role of Runx1 could enlarge our understanding of key marker genes in the skeletal development and an increased understanding of Runx1 could be helpful to identify treatments for osteoarthritis. This review provides the most up-to-date advances in the roles and bio-mechanisms of Runx1 in healthy joints and osteoarthritis from all currently published articles and gives novel insights in therapeutic approaches to OA based on Runx1.

Abstract
Peripheral nerve injury is common, and can lead to skeletal muscle atrophy and dysfunction. However, the underlying molecular mechanisms are not fully understood. The transcription factors have been proved to play a key role in denervated muscle atrophy. In order to systematically analyze transcription factors and obtain more comprehensive information of the molecular regulatory mechanisms in denervated muscle atrophy, a new transcriptome survey focused on transcription factors are warranted. In the current study, we used microarray to identify and analyze differentially expressed genes encoding transcription factors in denervated muscle atrophy in a rat model of sciatic nerve dissection. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses were used to explore the biological functions of differentially expressed transcription factors and their target genes related to skeletal muscle pathophysiology. We found that the differentially expressed transcription factors were mainly involved in the immune response. Based on correlation analysis and the expression trends of transcription factors, 18 differentially expressed transcription factors were identified. Stat3, Myod1, Runx1, Atf3, Junb, Runx2, Myf6, Stat5a, Tead4, Klf5, Myog, Mef2a, and Hes6 were upregulated. Ppargc1a, Nr4a1, Lhx2, Ppara, and Rxrg were downregulated. Functional network mapping revealed that these transcription factors are mainly involved in inflammation, development, aging, proteolysis, differentiation, regeneration, autophagy, oxidative stress, atrophy, and ubiquitination. These findings may help understand the regulatory mechanisms of denervated muscle atrophy and provide potential targets for future therapeutic interventions for muscle atrophy following peripheral nerve injury.

Abstract
OBJECTIVE Skeletal muscle is the major site of insulin action. There are limited data on the relationship between insulin action and skeletal muscle myogenic/regenerative potential. RUNX1 is a transcription factor which plays a role in muscle development and regeneration. The aim of our study was to assess the role of skeletal muscle myogenic/regenerative potential in the development of insulin resistance through the studies on RUNX1 transcription factor. DESIGN This study is a cross-sectional study. Experimental part with myoblast cell line culture. METHODS We examined 41 young healthy volunteers, 21 normal weight and 20 with overweight or obesity. Hyperinsulinemic-euglycemic clamp and vastus lateralis muscle biopsy were performed. In L6 myoblast and human skeletal muscle myoblasts (hSkMM) cell cultures, RUNX1 was silenced at two stages of development. Cell growth, the expression of markers of myogenesis, nuclei fusion index, Akt phosphorylation and glucose uptake were measured. RESULTS Skeletal muscle RUNX1 expression was decreased in overweight/obese individuals in comparison with normal-weight individuals and was positively related to insulin sensitivity, independently of BMI. Runx1 loss-of-function at the stage of myoblast inhibited myoblast proliferation and differentiation and reduced insulin-stimulated Akt phosphorylation and insulin-stimulated glucose uptake. In contrast, Runx1 knockdown in myotubes did not affect Akt phosphorylation, glucose uptake and other parameters studied. CONCLUSIONS Myogenic/regenerative potential of adult skeletal muscle may be an important determinant of insulin action. Our data suggest that muscle RUNX1 may play a role in the modulation of insulin action through its effect on myogenesis.

Abstract
Chloride intracellular channel protein 4 (CLIC4) has been implicated in different types of cancers, but the role of CLIC4 in the development of gastric cancer (GC) remains unknown. We analyzed the expression of CLIC4 in 102 pairs of gastric adenocarcinomas by western blot and real-time PCR. Our data revealed that the expression of CLIC4 is reduced in GC tumor tissues compared with adjacent normal tissues. The expression levels of CLIC4 correlate inversely with the clinical stage of GC. CLIC4 expression is lowest in MKN45 cells, which have the highest tumorigenic potential and express the highest levels of cancer stem cell markers CD44 and OCT4, compared with N87 and AGS cells. Exogenous overexpression of CLIC4 downregulated the expression of CD44 and OCT4, and inhibited migration, invasion and epithelial-mesenchymal transition (EMT). Moreover, anchorage-independent growth of GC cells was decreased and the cells became more sensitive to 5-fluorouracil and etoposide treatment when CLIC4 was overexpressed. The ability of N87 cells to form tumors in nude mice was enhanced when CLIC4 was silenced. We, for the first time, demonstrate that CLIC4 suppresses tumor growth by inhibiting cancer cell stemness and EMT.

Runt-related transcription factor-1 (RUNX1), also known as acute myeloid leukaemia 1 protein (AML1), is a member of the core-binding factor family of transcription factors which modulate cell proliferation, differentiation, and survival in multiple systems. It is a master-regulator transcription factor, which has been implicated in diverse signalling pathways and cellular mechanisms during normal development and disease. RUNX1 is best characterized for its indispensable role for definitive haematopoiesis and its involvement in haematological malignancies. However, more recently RUNX1 has been identified as a key regulator of adverse cardiac remodelling following myocardial infarction. This review discusses the role RUNX1 plays in the heart and highlights its therapeutic potential as a target to limit the progression of adverse cardiac remodelling and heart failure.

Runx1 promotes scar deposition and inhibits myocardial proliferation and survival during zebrafish heart regeneration. Development 2020; 147:dev186569.

Abstract
Runx1 is a transcription factor that plays a key role in determining the proliferative and differential state of multiple cell types, during both development and adulthood. Here, we report how Runx1 is specifically upregulated at the injury site during zebrafish heart regeneration, and that absence of runx1 results in increased myocardial survival and proliferation, and overall heart regeneration, accompanied by decreased fibrosis. Using single cell sequencing, we found that the wild-type injury site consists of Runx1-positive endocardial cells and thrombocytes that induce expression of smooth muscle and collagen genes. Both these populations cannot be identified in runx1 mutant wounds that contain less collagen and fibrin. The reduction in fibrin in the mutant is further explained by reduced myofibroblast formation and upregulation of components of the fibrin degradation pathway, including plasminogen receptor annexin 2A as well as downregulation of plasminogen activator inhibitor serpine1 in myocardium and endocardium, resulting in increased levels of plasminogen. Our findings suggest that Runx1 controls the regenerative response of multiple cardiac cell types and that targeting Runx1 is a novel therapeutic strategy for inducing endogenous heart repair.

Abstract
BACKGROUND DAXX is a transcription repressor that has been implicated in several types of cancers, but its role in the development of gastric cancer remains unknown. METHODS We analysed the expression of DAXX in 83 pairs of gastric cancer samples, including neoplastic and adjacent tissues, and correlated the expression levels with clinical stages. We also investigated the molecular mechanisms by which DAXX downregulation promotes cancer growth using both in vitro and in vivo models. RESULTS DAXX was downregulated in advanced gastric cancer samples. The expression of DAXX inversely correlates with that of cancer stem cell markers CD44 and Oct4 in gastric cancer lines. DAXX overexpression in gastric cancer cells inhibited migration, invasion and epithelial- mesenchymal transition (EMT). The inhibition of EMT was achieved through the repression of SNAI3, a key inducer of EMT, by recruiting HDAC-1 into the nucleus. Using a xenograft mouse model, we demonstrated that the MKN45 cells formed smaller tumours when DAXX was overexpressed. Wild-type AGS cells were not able to form tumours in nude mice, but in contrast, formed visible tumours when DAXX was silenced in the cells. CONCLUSION We for the first time demonstrated that DAXX functions as a tumour suppressor in gastric cancer by inhibiting stem cell growth and EMT.
