DNAJA4 suppresses epithelial-mesenchymal transition and metastasis in nasopharyngeal carcinoma via PSMD2-mediated MYH9 degradation. Cell Death Dis 2023; 14:697. [PMID: 37875476 PMCID: PMC10598267 DOI: 10.1038/s41419-023-06225-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2023] [Revised: 10/09/2023] [Accepted: 10/16/2023] [Indexed: 10/26/2023]
Abstract
Emerging evidence indicates that DNA methylation plays an important role in the initiation and progression of nasopharyngeal carcinoma (NPC). DNAJA4 is hypermethylated in NPC, while its role in regulating NPC progression remains unclear. Here, we revealed that the promoter of DNAJA4 was hypermethylated and its expression was downregulated in NPC tissues and cells. Overexpression of DNAJA4 significantly suppressed NPC cell migration, invasion, and EMT in vitro, and markedly inhibited the inguinal lymph node metastasis and lung metastatic colonization in vivo, while it did not affect NPC cell viability and proliferation capability. Mechanistically, DNAJA4 facilitated MYH9 protein degradation via the ubiquitin-proteasome pathway by recruiting PSMD2. Furthermore, the suppressive effects of DNAJA4 on NPC cell migration, invasion, and EMT were reversed by overexpression of MYH9 in NPC cells. Clinically, a low level of DNAJA4 indicated poor prognosis and an increased probability of distant metastasis in NPC patients. Collectively, DNAJA4 serves as a crucial driver for NPC invasion and metastasis, and the DNAJA4-PSMD2-MYH9 axis might contain potential targets for NPC treatments.

[PMID: 37717073 PMCID: PMC10505212 DOI: 10.1038/s41598-023-42019-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2023] [Accepted: 09/04/2023] [Indexed: 09/18/2023] Open
Abstract
Psoriasis, a chronic and systemic inflammatory disorder characterized by activation of the interleukin (IL)-23/IL-17 axis, may be associated with the intestinal microbiota through the so-called "gut-skin axis." Clusterin is a glycoprotein ubiquitously distributed in mammalian tissues; however, its role in psoriasis is unclear. Therefore, we evaluated the role of clusterin in psoriatic skin inflammation, systemic inflammation, and colitis using a murine model of IMQ-induced psoriasis. In IMQ-treated clusterin-knockout (clusterin-/-) mice, the expressions of inflammatory cytokines in clusterin-silenced human keratinocytes and intestinal microbial composition were analyzed. We also examined clusterin expression in the skin tissues of patients with psoriasis. IMQ-induced psoriatic skin inflammation is suppressed in clusterin-/- mice. Long-term administration of IMQ induced systemic inflammation and colitis; however, both were alleviated by the genetic deletion of clusterin. Genetic silencing of clusterin in human keratinocytes inhibited the production of inflammatory cytokines involved in the initiation and progression of psoriasis. The composition of the intestinal microbiota in IMQ-treated clusterin-/- and wild-type mice was different. Genetic deletion of clusterin suppressed the increase in the Firmicutes/Bacteroidetes (F/B) ratio. Skin tissues of patients with psoriasis showed high clusterin expression. In conclusion, inhibition of clusterin decreased psoriatic skin inflammation, systemic inflammation, colitis, and altered the F/B ratio in an IMQ-induced murine psoriasis model.

Abstract
The DNAJ family, a class of chaperone proteins involved in protein folding, assembly, and transport, plays an essential role in viral infections. However, the role of DNAJA4 (DnaJ Heat Shock Protein Family (Hsp40) Member A4) in the ranavirus infection has not been reported. This study demonstrates the function of the epithelial papilloma of carp (EPC) DNAJA4 in Chinese giant salamander (Andrias davidianus) iridovirus (CGSIV) replication. DNAJA4 consists of 1479 base pairs and encodes a 492 amino acid polypeptide. Sequence analysis has shown that EPC DNAJA4 contains a conserved J domain and shares 84% homology with Danio rerio DNAJA4 and 68% homology with Homo sapiens DNAJA4. EPC DNAJA4 was localized in the cytoplasm, and its expression was significantly upregulated after CGSIV infection. Overexpression of EPC DNAJA4 promotes CGSIV replication and CGSIV DNA replication. siRNA knockdown of DNAJA4 expression attenuates CGSIV replication and viral DNA replication. Overexpression and interference experiments have proved that EPC DNAJA4 is a pro-viral factor. Co-IP, GST-pulldown, and immunofluorescence confirmed the interaction between EPC DNAJA4 and CGSIV proliferating cell nuclear antigen (PCNA). Our results demonstrate for the first time that EPC DNAJA4 is involved in viral infection by promoting viral DNA replication and interacting with proteins associated with viral replication.

Abstract
Aims: To investigate DNA methylation patterns in early and terminal stages of erythropoiesis, and to explore the function of differentially methylated genes in erythropoiesis and erythroid disorders. Materials & methods: Differential analysis of DNA methylation and gene expression during erythropoiesis, as well as weighted gene coexpression network analysis of acute myeloid leukemia was performed. Results: We identified four candidate genes that possessed differential methylation in the promoter regions. DNAJA4 affected proliferation, apoptosis and enucleation during terminal erythropoiesis and was associated with the prognosis of acute myeloid leukemia. DNAJA4 was specifically highly expressed in erythroleukemia and is associated with DNA methylation. Conclusion: DNAJA4 plays a crucial role for erythropoiesis and is regulated via DNA methylation. Dysregulation of DNAJA4 expression is associated with erythroid disorders.

Amphibian-derived peptide homodimer OA-GL17d promotes skin wound regeneration through the miR-663a/TGF-β1/Smad axis. BURNS & TRAUMA 2022; 10:tkac032. [PMID: 35832307 PMCID: PMC9273405 DOI: 10.1093/burnst/tkac032] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 04/08/2022] [Indexed: 11/29/2022]
Abstract
Background Amphibian-derived peptides exhibit considerable potential in the discovery and development of new therapeutic interventions for clinically challenging chronic skin wounds. MicroRNAs (miRNAs) are also considered promising targets for the development of effective therapies against skin wounds. However, further research in this field is anticipated. This study aims to identify and provide a new peptide drug candidate, as well as to explore the underlying miRNA mechanisms and possible miRNA drug target for skin wound healing. Methods A combination of Edman degradation, mass spectrometry and cDNA cloning were adopted to determine the amino acid sequence of a peptide that was fractionated from the secretion of Odorrana andersonii frog skin using gel-filtration and reversed-phase high-performance liquid chromatography. The toxicity of the peptide was evaluated by Calcein-AM/propidium iodide (PI) double staining against human keratinocytes (HaCaT cells), hemolytic activity against mice blood cells and acute toxicity against mice. The stability of the peptide in plasma was also evaluated. The prohealing potency of the peptide was determined by MTS, scratch healing and a Transwell experiment against HaCaT cells, full-thickness injury wounds and scald wounds in the dorsal skin of mice. miRNA transcriptome sequencing analysis, enzyme-linked immunosorbent assay, real-time polymerase chain reaction and western blotting were performed to explore the molecular mechanisms. Results A novel peptide homodimer (named OA-GL17d) that contains a disulfide bond between the 16th cysteine residue of the peptide monomer and the sequence ‘GLFKWHPRCGEEQSMWT’ was identified. Analysis showed that OA-GL17d exhibited no hemolytic activity or acute toxicity, but effectively promoted keratinocyte proliferation and migration and strongly stimulated the repair of full-thickness injury wounds and scald wounds in the dorsal skin of mice. Mechanistically, OA-GL17d decreased the level of miR-663a to increase the level of transforming growth factor-β1 (TGF-β1) and activate the subsequent TGF-β1/Smad signaling pathway, thereby resulting in accelerated skin wound re-epithelialization and granular tissue formation. Conclusions Our results suggest that OA-GL17d is a new peptide drug candidate for skin wound repair. This study emphasizes the importance of exogenous peptides as molecular probes for exploring competing endogenous RNA mechanisms and indicates that miR-663a may be an effective target for promoting skin repair.
