Histone Acetylation in the Epigenetic Regulation of Bone Metabolism and Related Diseases. Stem Cells Int 2021; 2021:8043346. [PMID: 34326880 PMCID: PMC8310436 DOI: 10.1155/2021/8043346] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Accepted: 07/01/2021] [Indexed: 02/05/2023] Open
Abstract
As the earliest studied epigenetic modification, acetylation has been explored a lot through the years. While bone tissue acts as an indispensable part of body, researches aimed at the relationship between the bone and acetylation became necessary. Some environmental factors like diet may affect the metabolism status that some metabolites especially nicotinamide adenine dinucleotide (NAD) were found able to regulate intracellular histone acetylation in bone metabolism. This review focuses on representing the interaction among acetylation, metabolism, and the bone. The results showed that acetylation connects a lot with bone metabolism, while the explorations about related metabolites like acetyl-CoA or different environmental exposures are still limited. Some acetylation-related therapy methods of bone diseases based on metabolic regulation or epigenetic enzymes were also reviewed.

Epigenetic modification cooperates with Zeb1 transcription factor to regulate Bmp4 to promote chicken PGCs formation. Gene 2021; 794:145760. [PMID: 34116118 DOI: 10.1016/j.gene.2021.145760] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Revised: 05/26/2021] [Accepted: 06/04/2021] [Indexed: 11/20/2022]
Abstract
BMP4 is the critical gene of primordial germ cell formation in mammal, however, the mechanism of PGCs formation in chicken still unknown. In this research, we compared the evolution relationship of different species. Although the protein sequence is highly conservative between mouse, human and chicken, promotors vary among avian and mammal species. Therefore, it is easily to predict that there would be different regulation mechanism of Bmp4 expression in chicken. Here, we elucidate the function of chicken Bmp4 during PGCs formation. In vivo, Bmp4 can promote PGCs development and migration, and increase the expression of key genes (Cvh, c-kit, cxcr4, etc.). Whereas, the expression of these genes will decrease after knocking out Bmp4. After over-expression and knockout Bmp4 in vitro, we found that overexpression of Bmp4 could promote the formation of embryoid bodies (EB) and up-regulate the key genes of PGCs formation and migration, while knockout Bmp4 could inhibit the formation of embryoid bodies and decrease the expression of related genes. Flow and indirect immunofluorescence also indicated the same result. These all results proved that chicken Bmp4 could also promote the formation of PGCs. Furthermore, dual-luciferase activity detection showed that the promotor activity of Bmp4 was positively regulated by transcription factor Zeb1. Overexpression of Zeb1 can also increase the mRNA and protein expression of Bmp4. At the same time, DNA methylation inhibited Bmp4 transcription and histone methylation was able to promote its transcription. In conclusion, this study established that chicken Bmp4 can promote the formation of chicken PGCs. This gene is regulated by DNA, histone methylation and transcription factor Zeb1. These results lay a theoretical foundation for exploring the function and molecular mechanism of Bmp4 in the process of PGCs formation.

Phase II trial of single-agent panobinostat consolidation improves responses after sub-optimal transplant outcomes in multiple myeloma. Br J Haematol 2021; 193:160-170. [PMID: 32945549 PMCID: PMC8048685 DOI: 10.1111/bjh.17080] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Accepted: 08/11/2020] [Indexed: 01/23/2023]
Abstract
Panobinostat is a pan-deacetylase inhibitor that modulates the expression of oncogenic and immune-mediating genes involved in tumour cell growth and survival. We evaluated panobinostat-induced post-transplant responses and identified correlative biomarkers in patients with multiple myeloma who had failed to achieve a complete response after autologous transplantation. Patients received panobinostat 45 mg administered three-times weekly (TIW) on alternate weeks of 28-day cycles commencing 8-12 weeks post-transplant. Twelve of 25 patients (48%) improved their depth of response after a median (range) of 4·3 (1·9-9·7) months of panobinostat. In responders, T-lymphocyte histone acetylation increased after both three cycles (P < 0·05) and six cycles (P < 0·01) of panobinostat when compared to baseline, with no differences in non-responders. The reduction in the proportion of CD127+ CD8+ T cells and CD4:CD8 ratio was significantly greater, after three and six cycles of panobinostat compared to pre-transplant, in non-responders when compared to responders. Whole marrow RNA-seq revealed widespread transcriptional changes only in responders with baseline differences in genes involved in ribosome biogenesis, oxidative phosphorylation and metabolic pathways. This study confirmed the efficacy of panobinostat as a single agent in multiple myeloma and established acetylation of lymphocyte histones, modulation of immune subsets and transcriptional changes as pharmacodynamic biomarkers of clinical benefit.

Abstract
Some drugs can be used to treat multiple diseases, suggesting potential patterns in drug treatment. Determination of drug treatment patterns can improve our understanding of the mechanisms of drug action, enabling drug repurposing. A drug can be associated with a multilayer tissue-specific protein-protein interaction (TSPPI) network for the diseases it is used to treat. Proteins usually interact with other proteins to achieve functions that cause diseases. Hence, studying drug treatment patterns is similar to studying common module structures in multilayer TSPPI networks. Therefore, we propose a network-based model to study the treatment patterns of drugs. The method was designated SDTP (studying drug treatment pattern) and was based on drug effects and a multilayer network model. To demonstrate the application of the SDTP method, we focused on analysis of trichostatin A (TSA) in leukemia, breast cancer, and prostate cancer. We constructed a TSPPI multilayer network and obtained candidate drug-target modules from the network. Gene ontology analysis provided insights into the significance of the drug-target modules and co-expression networks. Finally, two modules were obtained as potential treatment patterns for TSA. Through analysis of the significance, composition, and functions of the selected drug-target modules, we validated the feasibility and rationality of our proposed SDTP method for identifying drug treatment patterns. In summary, our novel approach used a multilayer network model to overcome the shortcomings of single-layer networks and combined the network with information on drug activity. Based on the discovered drug treatment patterns, we can predict the potential diseases that the drug can treat. That is, if a disease-related protein module has a similar structure, then the drug is likely to be a potential drug for the treatment of the disease.

Abstract
Epithelial tissues provide tissue barriers and specialize in organs and glands. When epithelial homeostasis is physiologically or pathologically stimulated, epithelial cells produce mesenchymal cells through the epithelial-mesenchymal transition, forming new tissues, promoting the cure of diseases or leading to illness. A variety of cytokines are involved in the regulation of epithelial cell differentiation. Bone morphogenetic proteins (BMPs), especially the bone morphogenetic protein 4 (BMP4) has a variety of biological functions and plays a prominent role in the regulation of epithelial cell differentiation. BMP4 is an important regulatory factor of a series of life activities in vertebrates, which is also related to cell proliferation, differentiation and mobility, it also has relation with tumor development. This paper mainly reviews the mechanism of BMP4's regulation on epithelial tissues, as well as its effect on the growth, differentiation, benign lesions and malignant lesions of epithelial tissues, and expounds the function of BMP4 in epithelial tissues, to provide theoretical support for the research on reducing epithelial diseases.

Abstract
Branching morphogenesis is essential for the successful development of a functional lung to accomplish its gas exchange function. Although many studies have highlighted requirements for the bone morphogenetic protein (BMP) signaling pathway during branching morphogenesis, little is known about how BMP signaling is regulated. Here, we report that the protein arginine methyltransferase 5 (Prmt5) and symmetric dimethylation at histone H4 arginine 3 (H4R3sme2) directly associate with chromatin of Bmp4 to suppress its transcription. Inactivation of Prmt5 in the lung epithelium results in halted branching morphogenesis, altered epithelial cell differentiation and neonatal lethality. These defects are accompanied by increased apoptosis and reduced proliferation of lung epithelium, as a consequence of elevated canonical BMP-Smad1/5/9 signaling. Inhibition of BMP signaling by Noggin rescues the lung branching defects of Prmt5 mutant in vitro Taken together, our results identify a novel mechanism through which Prmt5-mediated histone arginine methylation represses canonical BMP signaling to regulate lung branching morphogenesis.

Abstract
Epithelial cells contribute to the development of various vital organs by generating tubular and/or glandular architectures. The fully developed forms of ductal organs depend on processes of branching morphogenesis, whereby frequency, total number, and complexity of the branching tissue define the final architecture in the organ. Some ductal tissues, like the mammary gland during pregnancy and lactation, disintegrate and regenerate through periodic cycles. Differentiation of branched epithelia is driven by antagonistic actions of parallel growth factor systems that mediate epithelial-mesenchymal communication. Transforming growth factor-β (TGF-β) family members and their extracellular antagonists are prominently involved in both normal and disease-associated (e.g., malignant or fibrotic) ductal tissue patterning. Here, we discuss collective knowledge that permeates the roles of TGF-β family members in the control of the ductal tissues in the vertebrate body.

Abstract
Cisplatin, a highly effective and widely used chemotherapeutic agent, has a major limitation for its nephrotoxicity. Currently, there are no therapies available to treat or prevent cisplatin nephrotoxicity. We recently identified a novel strategy for attenuating its nephrotoxicity in chemotherapy by histone deacetylase (HDAC) inhibitors via epigenetic modification to enhance bone morphogenetic protein 7 (BMP-7) expression. Cisplatin upregulated the activity of HDAC2 in the kidney. Inhibition of HDAC with clinically used trichostatin A (TSA) or valproic acid (VPA) suppressed cisplatin-induced kidney injury and epithelial cell apoptosis. Overexpression of HDAC2 promotes CP-treated tubular epithelium cells apoptosis. Chromatin immunoprecipitation assay clearly detected HDAC2 assosiation with BMP-7 promoter. Western blot and immunofluorescence results demonstrated that the expression of BMP-7 was clearly induced by TSA or VPA in vivo and in vitro. Interestingly, administration of recombinant BMP-7 (rhBMP-7) reduced cisplatin-induced kidney dysfunction. Moreover, BMP-7 treatment suppressed epithelial cell apoptosis and small interfering RNA-based knockdown of BMP-7 expression abolished HDAC inhibitors suppression of epithelial cell apoptosis in vitro. Results of current study indicated that TSA or VPA inhibited apoptosis of renal tubular epithelial cells via promoting the level of BMP-7 epigenetically through targeting HDAC2. Hence, HDAC inhibitors could be useful therapeutic agents for the prevention of cisplatin nephrotoxicity.
