[PMID: 38286266 DOI: 10.1016/j.gene.2024.148214] [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: 11/17/2023] [Revised: 01/19/2024] [Accepted: 01/24/2024] [Indexed: 01/31/2024]
Abstract
Acute myeloid leukemia (AML) is a malignant hematological disorder in which aberrant cytokine signaling and inflammation play a role in disease initiation and progression. Interleukin-40 (IL-40) is a novel cytokine encoded by the chromosome 17 open reading frame 99 (C17orf99) gene. This cytokine is involved in mediating inflammation but its biological significance in the pathogenesis of AML has not been investigated. In this case-control and observational study, mRNA expression and DNA methylation of the C17orf99 gene were evaluated in the peripheral blood of AML patients. In addition, the polymorphism of two novel intergenic variants of the C17orf99 gene, rs2004339 A/G and rs2310998 G/A, were explored using a real-time polymerase chain reaction assay. The study was conducted on 131 patients with AML and 106 controls and gene expression and DNA methylation were expressed as fold-change (2-ΔΔCt). Results revealed that mRNA expression of the C17orf99 gene was down-regulated in AML patients, particularly in females, while up-regulated expression was found in patients with hypoalbuminemia. For DNA methylation, it was up-regulated in AML patients, particularly in females, AML M5 subtype, and CD4-negative and CD14-positive peripheral blood cells. The mutant A allele and the corresponding homozygous AA genotype of rs2004339 was significantly associated with an increased risk of AML. The AA genotype was also associated with significantly up-regulated C17orf99 mRNA expression and DNA methylation of compared to the wild-type GG genotype. In conclusions, C17orf99 mRNA expression showed down-regulated levels in the peripheral blood of AML patients, while DNA methylation was up-regulated. The intergenic variant rs2004339 was associated with susceptibility to AML and had an effect on mRNA expression and DNA methylation.

Bani-Wais DFN, Ad'hiah AH. The 5' untranslated region variant rs3811050 C/T of the interleukin-38 encoding gene is associated with susceptibility to rheumatoid arthritis in Iraqi women. Mol Biol Rep 2024; 51:589. [PMID: 38683405 DOI: 10.1007/s11033-024-09529-y] [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: 02/16/2024] [Accepted: 04/05/2024] [Indexed: 05/01/2024]
Abstract
BACKGROUND Interleukin (IL)-38, the latest member of the IL-1 cytokine family, is proposed to have a pathogenic role in rheumatoid arthritis (RA). It is encoded by the IL1F10 gene, which harbors single nucleotide polymorphisms (SNPs) that may predict the risk of autoimmune diseases. Among them are 5' untranslated region (UTR) SNPs, which play a key role in post-transcriptional control, but have not been studied in Iraqi RA patients. METHODS Two novel IL1F10 5'UTR SNPs (rs3811050 C/T and rs3811051 T/G) were explored in RA and control women (n = 120 and 110, respectively). SNPs were genotyped using TaqMan assay. An ELISA kit was used to measure serum IL-38 concentrations. RESULTS A reduced risk of RA was associated with rs3811050 T allele and CT genotype (corrected probability [pc] = 0.01 and < 0.001, respectively), while there was no significant association with rs3811051. Haplotype analysis demonstrated that C-T haplotype was associated with a 1.65-fold greater risk of RA, whereas a reduced risk was linked to T-G haplotype. IL-38 concentrations were higher in patients than in controls (p < 0.001). In addition, IL-38 showed acceptable performance in distinguishing between RA and control women (p < 0.001). When IL-38 concentrations were stratified according to SNP genotypes, no significant differences were found. CONCLUSIONS The rs3811050 variant was more likely to affect RA susceptibility in Iraqi women, and the T allele may play a role in reducing disease risk. IL-38 concentrations were elevated in RA patients, but were not affected by the rs3811050 and rs3811051 genotypes.

Abstract
BACKGROUND A case-control study was performed to explore eight pro-inflammatory and anti-inflammatory cytokines, namely interleukin (IL)-1α, IL-1Ra (IL-1 receptor antagonist), IL-12, IL-17A, IL-31, IL-33, CXCL10 (C-X-C motif chemokine ligand 10), and CXCL16, with the aim to understand their role in ankylosing spondylitis (AS) pathogenesis and evaluate their utility as markers to differentiate between diseased and healthy individuals. Among these cytokines, IL-31 and CXCL16 have not been well studied in AS. PATIENTS AND METHODS The study included 94 male patients with AS and 91 age-matched control males. Interleukin and chemokine levels were measured using ELISA kits. RESULTS Serum levels of IL-17A, CXCL10, and CXCL16 were significantly elevated in patients compared to controls, while IL-31 levels were significantly decreased in patients. IL-17A, CXCL10, and CXCL16 were associated with an increased risk of AS, while IL-31 was associated with a decreased risk of disease (odds ratio = 1.22, 1.78, 1.14, and 0.89, respectively). As indicated by the area under the curve (AUC), IL-17A, IL-31, CXCL10, and CXCL16 were potential markers to differentiate between AS patients and controls (AUC = 0.877, 0.735, 0.8, and 0.7, respectively). IL-1α, IL-1Ra, IL-12, and IL-33 levels showed no significant variations between patients and controls. CONCLUSIONS Among the eight cytokines examined, IL-17A, CXCL10, and CXCL16 were up-regulated in the serum of AS patients, while IL-31 was down-regulated. The levels of IL-1α, IL-1Ra, IL-12, and IL-33 showed no significant differences between patients and controls. Serum levels of all cytokines were not affected by disease duration, HLA-B27 positivity, or disease activity.

Abstract
Interleukins are a group of proteins that have a wide range of complex functions and are believed to be involved in several diseases and conditions. In particular, interleukin-40 (IL-40) is a recently identified cytokine associated with B cells that was first introduced by Catalan et al. in 2017. This cytokine has several roles in the body, including functioning in the formation of B cells in the bone marrow, IgA production, and expression in the intestinal microbiome. Moreover, IL-40 appears to be involved in numerous autoimmune and inflammatory conditions, such as rheumatoid arthritis, systemic lupus erythematosus, primary Sjogren's syndrome, ankylosing spondylitis, type 2 diabetes, Graves' disease, and hepatic cell carcinoma. Our understanding of this molecule is quite restricted due to its novelty. However, because of its inflammatory characteristics, there is a high probability that it contributes to a variety of inflammatory disease complications. The aim of the present review is to highlight all available data on the importance of assessing IL-40 levels in human diseases up to now, which could be used as a diagnostic biomarker for the onset or progression of numerous inflammatory diseases.

Mol Immunol 2023; 164:39-46. [PMID: 37951185 DOI: 10.1016/j.molimm.2023.11.002] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 10/25/2023] [Accepted: 11/03/2023] [Indexed: 11/13/2023]
Abstract
Interleukin-40 (IL-40) is a novel cytokine encoded by the chromosome 17 open reading frame 99 (C17orf99) gene. Recent studies have shown that IL-40 levels are significantly up-regulated in patients with rheumatoid arthritis (RA). However, the association of genetic variants of the C17orf99 gene with the risk of RA has not been investigated. In this case-control study, two intergenic variants, rs2004339 A/G and rs2310998 G/A, were genotyped for the first time in 120 Iraqi women with RA (30 newly diagnosed [ND] and 90 medicated [MD; treated with the tumor necrosis inhibitor etanercept plus methotrexate]) and 110 control women using TaqMan 5'-allele discrimination method. Serum IL-40 levels were also determined using an enzyme-linked immunosorbent assay kit. Multinomial logistic regression analysis was used to analyze rs2004339 and rs2310998 under five genetic models (allele, recessive, dominant, over-dominant, and co-dominant). Results revealed that the mutant A allele (allele model) and the homozygous AA genotype (co-dominant model) of rs2004339 were significantly associated with an increased risk of RA (odds ratio [OR] = 3.37 and 7.44, respectively; corrected probability [pc] < 0.001), while rs2310998 showed no association with RA risk. When comparing the allele and genotype frequencies of rs2004339 and rs2310998 between ND and MD patients, there were no statistically significant differences. Haplotype analysis of the two variants (in the order rs2004339-rs2310998) revealed that haplotypes A-A (OR = 1.72; pc = 0.024) and A-G (OR = 2.85; pc < 0.001) were associated with an increased risk of RA. IL-40 levels (median and interquartile range) were significantly elevated in RA patients compared to controls (29.3 [15.5-41.5] vs. 12.6 [7.4-18.8] pg/mL; p < 0.001). IL-40 levels were not influence by disease duration or disease activity, but the rs2310998 genotypes had an effect; IL-40 levels were significantly higher in women with the AA genotype than in women with the GG genotype (20.1 [12.9-37.1] vs. 15.8 [8.3-22.6] pg/mL; p = 0.006). Regarding medication, IL-40 tended to show elevated levels in ND cases compared to MD cases but without a significant difference. In conclusion, the mutant A allele and the mutant-type AA genotype of the intergenic variant rs2004339 were associated with an increased risk of RA among Iraqi women. Serum IL-40 levels were also elevated in patients, particularly ND patients, and were positively affected by the mutant-type AA genotype. Accordingly, the role of IL-40 in the pathogenesis of RA has been indicated.

Abstract
Ankylosing spondylitis (AS) is a chronic autoimmune disease. The purpose of this study was to investigate the levels of serum IL-36γ in AS patients and their association with AS. The study enrolled 131 subjects, including 45 with active AS, 46 with inactive AS, and 40 healthy controls (HCs). The basic clinical information of each participant was obtained through physical examination and relevant clinical medical records. Serum IL-36γ levels were detected through an enzyme-linked immunosorbent assay. Serum IL-36γ levels in the active AS group were significantly higher than those in the HC group (94.72 vs. 65.76 pg/mL, P = 0.0087). The serum IL-36γ concentration in the inactive AS group was increased as compared to that in the HC group (100.90 vs. 65.76 pg/mL, P = 0.0138). Correlation analysis indicated that serum IL-36γ was positively correlated with glutamyl transferase in the active AS group (P = 0.0172), while serum IL-36γ was positively correlated with uric acid in the inactive AS group (P = 0.0151). The area under the curve (AUC) for IL-36γ was 0.6824 (P = 0.0009), and the AUC for IL-36γ combined with the erythrocyte sedimentation rate and C-reactive protein levels was 0.8102 (P < 0.0001), according to receiver operating characteristic curve analysis. This study found that serum IL-36γ levels were elevated in AS patients and correlated with disease activity. Our results suggest that IL-36γ may be involved in the progression of AS disease and is a potential biomarker for AS.

Abstract
Interleukin (IL)-36 is a family of cytokines that belongs to the larger IL-1 superfamily. IL-36 agonist/antagonist binds to the interleukin-36 receptor involving in physiological inflammation regulation and pathogenesis of many inflammatory diseases. In inflammatory joint diseases, the expression of IL-36 changes, and some studies have initially explored the role of IL-36 in these diseases. In psoriatic arthritis, IL-36 signal mediates plasma cell and fibroblast-like synoviocyte crosstalk presenting IL-36 agonist/antagonist imbalance. In rheumatoid arthritis, IL-36 agonists induce fibroblast-like synoviocyte to produce pro-inflammatory factors, while IL-36 antagonist deficiency leads to lesion progression. In osteoarthritis, IL-36 agonists induce chondrocytes to produce catabolic enzymes and pro-inflammatory factors. This article reviews the expression and function of IL-36 in different inflammatory joint diseases to provide a reference for revealing their pathogenic mechanisms and discovering therapeutic targets.
