Fertil Steril 2021; 116:1139-1146. [PMID: 34119324 DOI: 10.1016/j.fertnstert.2021.05.093] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 05/13/2021] [Accepted: 05/14/2021] [Indexed: 01/10/2023]
Abstract
OBJECTIVE To study the relationship between circulating chemokine cysteine-cysteine motif ligand (CCL) 5 levels and cysteine-cysteine chemokine receptor type 5 (CCR5) expression in peripheral blood mononuclear cells (PBMCs) and adipose tissue with hyperandrogenism and insulin resistance in patients with polycystic ovary syndrome (PCOS). DESIGN Case-control study. SETTING University teaching hospital. PATIENT(S) Fifteen women with PCOS and 15 controls matched for body mass index and age were enrolled in this study. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Plasma levels of CCL3, CCL4, and CCL5 were determined using enzyme-linked immunosorbent assay kits, and omental adipose tissue and PBMCs were analyzed using real-time polymerase chain reaction to determine the expression level of CCR5 in participants. RESULT(S) Levels of CCL5 were significantly higher in women with PCOS. Expression of CCR5 in adipose tissue and PBMCs was significantly higher in women with PCOS compared with that in women in the control group. Cysteine-cysteine chemokine receptor type 5 expression also was upregulated in THP-1 cells after chronic exposure to testosterone. Levels of CCL5 had a significant positive correlation with testosterone levels in women with PCOS. Moreover, CCR5 showed a positive correlation with fasting glucose levels, homeostasis model insulin resistance index, and C-reactive protein. CONCLUSION(S) Increased levels of CCL5 and overexpression of CCR5 in PBMCs and adipose tissue are associated with hyperandrogenism and insulin resistance in women with PCOS. Additionally, CCR5 and CCL5 may be used as biomarkers in the pathogenesis of PCOS.

[PMID: 33811432 DOI: 10.1111/nep.13881] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2021] [Revised: 03/02/2021] [Accepted: 03/21/2021] [Indexed: 12/11/2022]
Abstract
BACKGROUND In this study, we aimed to explore whether COL1A2 and miR-1297 participated in the progression of diabetic nephropathy (DN) in vitro and classified the underlying mechanisms. METHODS d-Glucose (30 mM; high glucose, HG)-stimulated HK-2 cells were used to mimic DN condition. RNA and non-coding RNA profiles were from Gene Expression Omnibus (GEO) database. The interaction between miR-1297 and COL1A2 was measured by dual-luciferase reporter assay. Gene Set Enrichment Analysis (GSEA) method was conducted to analyse COL1A2-associated signalling pathways. The role of miR-1297/COL1A2 in biological behaviours of HG-induced HK-2 cells were analysed by cell counting kit-8 and apoptosis assays. RESULTS Bioinformatics analysis revealed that COL1A2 was up-regulated in DN tissues. We predicted and verified miR-1297 as the regulatory miRNA of COL1A2, and the expression of miR-1297 was decreased in DN tissues and HG-stimulated HK-2 cells. Overexpression of miR-1297 could promote cell proliferation and inhibit apoptosis to protect HK-2 cells from HG-induced damage. And knockdown of COL1A2 enhanced the protective effects of miR-1297 on HG-stimulated HK-2 cells. GSEA results revealed that several inflammatory pathways were enriched in COL1A2 high-expression group. Meanwhile, transfection of miR-1297 reduced the phosphorylation of NFκB and expression of three important pro-inflammatory genes including cytokine CCL5, adhesion molecules ICAM1 and VCAM1 via targeting COL1A2. These results suggested that miR-1297 protected HG-treated HK-2 cells probably through suppressing inflammation via targeting COL1A2. CONCLUSION This study sheds a light on the role miR-1297/COL1A2 in DN progression and provides a novel promising therapy strategy for suppressing DN progression.

Int J Chronic Dis 2019; 2019:2053015. [PMID: 30713847 PMCID: PMC6333004 DOI: 10.1155/2019/2053015] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2018] [Revised: 11/02/2018] [Accepted: 12/13/2018] [Indexed: 12/26/2022] Open
Abstract
The unique variants or biomarkers of individuals help to understand the pathogenesis as well as the potential risk of individuals or patients to diabetic nephropathy (DN). The aim of this study was to investigate the association of a genetic polymorphism of monocyte chemoattractant protein-1 (CCL2-rs3917887), chemokine receptor 5 (CCR5-rs1799987), engulfment and cell mortality (ELMO1-rs74130), and interleukin-8 (IL8-rs4073) with the development of DN among Malaysian type 2 diabetes mellitus (T2DM) patients. More than one thousand diabetic patients were examined and a total of 652 T2DM patients were tested comprising 227 Malays (nonnephrotic=96 and nephrotic=131), 203 Chinese (nonnephrotic=95 and nephrotic=108), and 222 Indians (nonnephrotic=136 and nephrotic=86). DNA Sequenom mass ARRAY was employed to identify polymorphisms in CCL2, CCR5, ELMO1, and IL8 genes. DNA was extracted from the secondary blood samples taken from the T2DM patients. The alleles and genotypes were tested using four genetic models and the best mode of inheritance was chosen. CCR5 rs1799987 (G>A) showed strong association with the development of diabetic nephropathy only among the Chinese with OR=6.71 (2.55-17.68) 95% CI while IL8 rs4073 (T>A) showed association with nephropathy only among the Indians with OR=1.57 (0.66-3.71) 95% CI. The additive model was the best model for the mode of inheritance of all the genes. The contribution of genetic variants differs across ethnic groups or background. Further studies which involve environmental risk factors should be taken into consideration.

Effects of CCR5 59029G/A polymorphism on the risk to diabetic nephropathy. Oncotarget 2017; 8:106926-106934. [PMID: 29291000 PMCID: PMC5739785 DOI: 10.18632/oncotarget.22148] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2016] [Accepted: 06/13/2017] [Indexed: 11/25/2022] Open
Abstract
Background Diabetic nephropathy (DN) causes high mortality in patients with diabetes mellitus and imposes heavy burden on individuals and society. In previous studies, various researches have investigated the association of DN with CCR5 59029G/A polymorphism, but relevant findings were controversial. Therefore, we performed this meta-analysis to obtain a conclusion on this issue. Results CCR5 59029G/A polymorphism showed significant risk-increasing effects on DN in all analyses under AA vs. GG, AA+GA vs. GG, AA vs. GG+GA, A vs. G and GA vs. GG model contrasts. Besides, a similar result was also obtained in Asian and type 2 diabetes mellitus groups under these five contrasts after subgroup analyses. Methods The relevant publications were searched from the electronic databases and other sources. The association intensity between CCR5 59029G/A polymorphism and DN susceptibility was measured using pooled odds ratios (ORs) with corresponding 95% confidence intervals (95% CIs). Inter-study heterogeneity was inspected with Q test, and sensitivity analysis was conducted to verify the stability of the final outcomes by removing one study each time in turn. Begg's funnel plot and Egger's test were utilized to examine publication bias among selected studies. Conclusion CCR5 59029G/A polymorphism is significantly related to enhanced susceptibility to DN, especially in Asian populations and people with type 2 diabetes mellitus.

Abstract
Chemokine receptor-ligand interaction regulates transmigration of lymphocytes and monocytes from circulation to the inflammatory sites. CC chemokine receptors, chemokine receptor 2(CCR2) and 5 (CCR5) are important in recruitment of immune cells as well as non-immune cells under pathological condition. CCR2, CCR5 and their ligands (CCL2 and CCL5) are major contributor to the autoimmune and inflammatory diseases and cancer. Currently studies are being done to explore genetic variations in chemokine genes and their involvement in diseases that could make clear disease severity and deaths. Conflicting results of studies in different populations and diseases promoted to investigate chemokines genetic polymorphisms in miscellaneous diseases. This study is aimed to evaluate the influence of chemokines genetic polymorphisms in pathogenesis and outcome of prevalent non infectious diseases. Present study demonstrates the likely role played by genetic variations in drug response and evolution. Moreover this study highlights chemokine as therapeutic target and diagnostic biomarker in pathological condition.

Abstract
Aims/Introduction Chemokine ligand 5 (CCL5) is a member of the CC‐chemokine family expressed in various organs. It contributes to the migration of monocytes/macrophages into injured vascular walls by binding with its receptor chemokine receptor 5 (CCR5). Many studies have accessed the association between CCL5/CCR5 gene promoter polymorphisms and diabetic microvascular complications (DMI). However, the results are conflicting and inconclusive. The aim of the present study was to evaluate the association more precisely. Materials and Methods Trials were retrieved through PubMed, Embase, Medline, China National Knowledge Infrastructure, Web of Science and Cochrane database without restrictions on language. The pooled odds ratio (OR) and 95% confidence interval (CI) were used to describe the strength of association with DMI. Results Data were obtained from 11 case–control studies that included 2,737 DMI patients and 2,435 diabetic control subjects. In the overall analysis, the CCL5‐403 G/A and CCL5‐28 C/G gene polymorphisms were not significantly associated with the risk of DMI. However, CCR5‐59029 G/A was an independent risk factor of DMI in a dominant model (OR 1.77, 95% CI 1.06–2.97). Subgroup analysis showed that the risk of the CCR5 59029A‐positive genotype was significant in Asians (OR 2.08, 95% CI 1.68–2.57). In addition, the CCR5 59029A‐positive genotype was associated with increased risk of albuminuria. Conclusions There were no associations of CCL5 gene promoter polymorphism with the risk of DMI. However, the 59029A polymorphism in CCR5 might affect individual susceptibility for DMI.

BMC MEDICAL GENETICS 2014; 15:103. [PMID: 25280384 PMCID: PMC4411872 DOI: 10.1186/s12881-014-0103-8] [Citation(s) in RCA: 40] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/06/2014] [Accepted: 08/26/2014] [Indexed: 02/08/2023]
Abstract
Background Diabetes mellitus is the most common chronic endocrine disorder, affecting an estimated population of 382 million people worldwide. It is associated with microvascular and macrovascular complications, including diabetic nephropathy (DN); primary cause of end-stage renal disease. Different inflammatory and angiogenic molecules in various pathways are important modulators in the pathogenesis and progression of diabetic nephropathy. Differential disease risk in DN may be partly attributable to genetic susceptibility. In this meta-analysis, we aimed to determine which of the previously investigated genetic variants in these pathways are significantly associated with the development of DN and to examine the functional role of these genes. Methods A systematic search was conducted to collect and analyze all studies published till June 2013; that investigated the association between genetic variants involved in inflammatory cytokines and angiogenesis and diabetic nephropathy. Genetic variants associated with DN were selected and analyzed by using Comprehensive Meta Analysis software. Pathway analysis of the genes with variants showing significant positive association with DN was performed using Genomatix Genome Analyzer (Genomatix, Munich, Germany). Results After the inclusion and exclusion criteria for this analysis, 34 studies were included in this meta-analysis. 11 genetic variants showed significant positive association with DN in a random-effects meta-analysis. These included genetic variants within or near VEGFA, CCR5, CCL2, IL-1, MMP9, EPO, IL-8, ADIPOQ and IL-10. rs1800871 (T) genetic variant in IL-10 showed protective effect for DN. Most of these eleven genetic variants were involved in GPCR signaling and receptor binding pathways whereas four were involved in chronic kidney failure. rs833061 [OR 2.08 (95% CI 1.63-2.66)] in the VEGFA gene and rs3917887 [OR 2.04 (95% CI 1.64-2.54)] in the CCL2 gene showed the most significant association with the risk of diabetic nephropathy. Conclusions Our results indicate that 11 genetic variants within or near VEGFA, CCR5, CCL2, IL-1, MMP9, EPO, IL-8, ADIPOQ and IL-10 showed significant positive association with diabetic nephropathy. Gene Ontology or pathway analysis showed that these genes may contribute to the pathophysiology of DN. The functional relevance of the variants and their pathways can lead to increased biological insights and development of new therapeutic targets.
