Abstract
TRAF6 is a key immune gene that plays a significant role in toll-like receptor signal transduction and activates downstream immune genes involved in antiviral immunity in fish. To explore the role of TRAF6 in Epithelioma papulosum cyprini (EPC) cells, we knocked out the TRAF6 gene using the Clustered Regularly Interspaced Short Palindromic Repeats-Cas9 (CRISPR-Cas9) technique and then analyzed the transcriptomes of the knockout cells. In this study, we identified that 232 transcripts were differentially expressed in naive cells. Using the pipeline, we identified 381 novel lncRNAs in EPC cells, 23 of which were differentially expressed. Gene Ontology enrichment analysis demonstrated that differentially expressed genes (DEG) are implicated in various immune processes, such as neutrophil chemotaxis and mitogen-activated protein kinase binding. In addition, the KEGG pathway analysis revealed enrichment in immune-related pathways (Interleukin-17 signaling pathway, cytokine-cytokine receptor interaction, and TNF signaling pathway). Furthermore, the target genes of the differentially expressed lncRNAs were implicated in the negative regulation of interleukin-6 and tumor necrosis factor production. These results indicate that lncRNAs and protein-coding genes participate in the regulation of immune and metabolic processes in fish.

miRNA-Induced Downregulation of IPMK in Macrophages Mediates Lipopolysaccharide-Triggered TLR4 Signaling. Biomolecules 2023; 13:biom13020332. [PMID: 36830701 PMCID: PMC9952907 DOI: 10.3390/biom13020332] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Revised: 01/27/2023] [Accepted: 02/07/2023] [Indexed: 02/11/2023] Open
Abstract
Inositol polyphosphate multikinase (IPMK) is a pleiotropic enzyme responsible for the production of inositol polyphosphates and phosphoinositide. IPMK in macrophages was identified as a key factor for the full activation of the Toll-like receptor 4 (TLR4) signaling pathway and inflammation by directly interacting with tumor necrosis factor receptor-associated factor 6 (TRAF6). Here, dynamic changes of IPMK levels in lipopolysaccharide (LPS)-stimulated macrophages and their functional significance were investigated. Both the mRNA and protein levels of IPMK were acutely decreased in mouse and human macrophages when cells were stimulated with LPS for between 1 and 6 h. Analysis of the 3' untranslated region (UTR) of mouse IPMK mRNA revealed a highly conserved binding site for miR-181c. Transfection of miR-181c mimics into RAW 264.7 macrophages led to decreased IPMK 3'UTR-luciferase reporter activity and lowered endogenous IPMK levels. When the genomic deletion of a 33-bp fragment containing a putative miR-181c-binding site was introduced within the IPMK 3'UTR of RAW 264.7 macrophages (264.7Δ3'UTR), LPS-triggered downregulation of IPMK levels was prevented. LPS treatment in 264.7Δ3'UTR macrophages decreased TLR4-induced signaling and the expression of proinflammatory cytokines. In response to LPS stimulation, K63-linked ubiquitination of TRAF6 was impaired in 264.7Δ3'UTR macrophages, suggesting an action of IPMK in the suppression of TRAF6 activation. Therefore, our findings reveal that LPS-mediated suppression of IPMK regulates the full activation of TLR4 signaling and inflammation in macrophages.

Abstract
Regulation of osteoclastogenesis and bone-resorbing activity can be an efficacious strategy for treating bone loss diseases because excessive osteoclastic bone resorption leads to the development of such diseases. Here, we investigated the role of (-)-tubaic acid, a thermal degradation product of rotenone, in osteoclast formation and function in an attempt to identify alternative natural compounds. (-)-Tubaic acid significantly inhibited receptor activator of nuclear factor-κB ligand (RANKL)-mediated osteoclast differentiation at both the early and late stages, suggesting that (-)-tubaic acid affects the commitment and differentiation of osteoclast progenitors as well as the cell-cell fusion of mononuclear osteoclasts. (-)-Tubaic acid attenuated the activation of extracellular signal-regulated kinase (ERK) and expression of nuclear factor of activated T-cells cytoplasmic 1 (NFATc1) and its target genes in response to RANKL. Furthermore, a pit-formation assay revealed that (-)-tubaic acid significantly impaired the bone-resorbing activity of osteoclasts. Our results demonstrated that (-)-tubaic acid exhibits anti-osteoclastogenic and anti-resorptive effects, indicating its therapeutic potential in the management of osteoclast-related bone diseases.

JOURNAL OF ETHNOPHARMACOLOGY 2022; 286:114928. [PMID: 34929309 DOI: 10.1016/j.jep.2021.114928] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 12/10/2021] [Accepted: 12/15/2021] [Indexed: 06/14/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Herbs have been commonly used for the treatment of rheumatoid arthritis (RA). It has been verified that Erteng Tongbi Decoction has good therapeutic effects on RA, while, relatively few studies on the relationship between its components and anti-rheumatoid efficacy were carried out. AIM OF THE STUDY To discuss the anti-RA effects of Erteng Tongbi Decoction on collagen-induced arthritis (CIA) in mice and the influence of T cell differentiation and cytokines balance. MATERIALS AND METHODS Separate researches on the two traditional Chinese medicines of the Erteng Tongbi Decoction were conducted. First, a murine peritoneal macrophage model was established, and then the cytokines levels and macrophage maturity were measured to select the best extraction solvent. Furthermore, ethanol extracts were partitioned successively with four kinds of solvents, and the anti-inflammatory parts were selected by the same vitro model. Subsequently, mice were arbitrarily divided into control, CIA model, positive control, effective parts alone or in combination. After 20 days of oral administration, the weight, hind paw volume, rheumatism index value, and the pathological changes were checked to assess the obvious level of arthritis. Furthermore, the levels of IL-6, TNF-α, IL-10, and IL-17A in serum and the balance of Th17/Treg and Th1/Th2 cells in spleen and mesenteric lymph nodes (MLN) was detected. Finally, the major active constituents were identified. RESULTS In vitro, the anti-inflammatory effects of ethanol extracts was much better than water extract. In addition, the effective parts of Celastrus orbiculatus Thunb. ethanol extract were petroleum ether parts and dichloromethane parts. The effective parts of Spatholobus suberectus Dunn. ethanol extracts was petroleum ether parts and ethyl acetate parts screened. In vivo, effective parts compatibility could inhibit the progression of inflammation by modulating T cell differentiation and cytokines balance. Constituent analysis revealed that effective parts contained sesquiterpenes alkaloids, phenolic acids, and flavanols. CONCLUSIONS Erteng Tongbi Decoction could notably ameliorate CIA mice by modulating T cell differentiation and cytokines balance and support its application in folk medicine.

Abstract
A family of inositol hexakisphosphate kinases (IP6Ks) catalyzes the production of inositol pyrophosphate IP7 (5-diphosphoinositolpentakisphosphate) which is known to modulate various biological events such as cell growth. While targeting IP6K1 in various cancer cells has been well reported to control cancer cell motility and invasiveness, the role of host IP6K1 in tumor progression remains unknown. By using a syngeneic MC38 murine mouse colon carcinoma model, here we examined how host IP6K1 in the tumor microenvironment influences tumor growth. In IP6K1 knockout (KO) mice, the growth of MC38 tumor cells was markedly accelerated and host survival was significantly shortened compared with wild-type (WT). Our flow cytometric analysis revealed that tumors grown in IP6K1 KO mice had lower immune suppressive myeloid cells and M1 polarized macrophages. Notably, infiltration of both antigen-presenting dendritic cells and CD8+ cytotoxic T lymphocytes into the tumor tissues was remarkably abrogated in IP6K1 KO condition. These studies suggest that enhanced tumor growth in IP6K1 KO mice resulted from reduced anti-tumor immunity due to disturbed immune cell actions in the tumor microenvironment. In conclusion, we demonstrate that host IP6K1 acts as a tumor suppressor, most likely by fine-tuning diverse tumor-immune cell interactions, which might have implications for improving the host response against cancer progression.
