Even though an allelic model (odds ratio [OR] = 0.63, 95% confidence interval [CI] = 0.41-0.96) and a homozygote comparison (OR = 0.52, 95% CI = 0.30-0.93) showed that the IL-6 (-174 G/C) polymorphism was marginally associated with PCOS.
The genotype IL-6 distribution did differ between the control group (CC 9.6%, GC 63.4%, GG 27.0%) and the PCOS patients (CC 4.7%, GC 29.4%, GG 65.9%) (p<0.001).
A common polymorphism of the IL6 promoter, although not associated with the presence of PCOS, is associated with the clinical characteristics of women affected by this condition.
Gene polymorphism of IL-6 -174 G>C is a risk factor for PCOS in Turkish patients, but we found no relationship between the cardiovascular risk factors and IL-6 -174 G>C gene polymorphism in women with PCOS and healthy subjects.
The pooled odds ratio between IL-6-174 G/C polymorphism and susceptibility of PCOS under allele (C/G), dominant (CC+GC/GG) and recessive (CC/GG+GC) models were 0.63 (95%CI, 0.41-0.96), 0.53 (95%CI, 0.26-1.08) and 0.67 (95%CI, 0.39-1.16), respectively.
The genotype IL-6 distribution did differ between the control group (CC 9.6%, GC 63.4%, GG 27.0%) and the PCOS patients (CC 4.7%, GC 29.4%, GG 65.9%) (p<0.001).
Sequence analyses of the PPAR gamma gene indicated that neither the common polymorphisms P12A or H478 H, nor novel polymorphisms (E79Q, V32G, -39 T>C, c.480 +33 t > g,) or unique sequence variations (S22S, A23A, T41A, S226C, K272 T, I484I, c.819 +24 a>c) detected in this investigation revealed evidence for a direct association of PPAR gamma with altered IL-7, IL-1beta, IL-6 and TNFalpha levels in PCOS patients.
Most studies occurred in Asia; most SNPs studied were in IL1B -511, TNF -1031, and IL6-174; and most of them were associated with the susceptibility to PCOS development.
The current study was aimed to evaluate the association between IL-6 gene -174 G/C promoter polymorphism and Polycystic Ovary Syndrome in South Indian women.
Eligible studies reporting an association between the IL-6rs1800795 polymorphism and PCOS susceptibility were included from PubMed, Embase, Web of Science, and the Cochrane Library up to December 1, 2017.
Person's correlations between PRE values and delta changes (i.e., exercise effect) showed significant, negative associations for plasma IL-1β (r = -0.92, p < 0.0001), TNF-α (r = -0.72, p = 0.0100) and IL-6 (r = -0.58, p = 0.05), and muscle TNF-α (r = -0.95, p < 0.0001), IKKα/β (r = -0.75, p = 0.005), and JNK (r = -0.94, p < 0.0001) in PCOS.
The results showed that IL-6 may be an early low-grade chronic inflammatory marker among PCOS patients with IRS-2 polymorphism in Taiwanese population.
Increased expression of <i>Il-6</i> mRNA in the visceral adipose tissue of polycystic ovarian rats may be one cause of insulin resistance observed in them and resveratrol as an anti-inflammatory and anti-hyperglycemic agent may decrease the risk of diabetes by reduction of expression of pro-inflammatory cytokines TNF-α and IL-6 in PCOS patients.
Immunohistochemistry scoring showed increased expression of CCL2 in eEP(PCOS) and eSF(PCOS) compared with eEP(Ctrl) and eSF(Ctrl) and IL-6 in eEP(PCOS) compared with eEP(Ctrl).
These data suggest that IL-6 contributes to the development of PCO by promoting TGF-β<sub>2</sub> activation and ECM synthesis through a JAK/STAT3 signaling-dependent mechanism.
To provide high-quality evidence about the effect of treatment with metformin on CRP and IL-6 in PCOS, relevant studies that assessed the serum levels of CRP and IL-6 in women with PCOS receiving metformin treatment were reviewed and analyzed.
In the PCOS+l-carnitine group, serum concentrations of FSH and FRAP increased significantly, whereas there were significant decreases in serum concentrations of testosterone, LH, MDA, IL-6 and TNF-α, as well as in the percentage of TUNEL-positive apoptotic cells, compared with the PCOS group. l-Carnitine improves folliculogenesis and is therefore suggested as a therapeutic supplement in the treatment of PCOS.
There were no significant difference between-group changes in glucose transporter 1 (GLUT-1), IL-6 and transforming growth factor beta (TGF-β) in PBMC of PCOS women.
<b>Conclusions:</b> This <i>post-hoc</i> analysis revealed that 12 weeks of atorvastatin treatment significantly decreased the markers of adipose tissue dysfunction and inflammation, namely ASP, IL-6 and MCP-1 in obese women with PCOS.
In this case-control study, plasma levels of hepcidin, IL-6, and ferritin using ELISA method and serum iron levels using a spectrophotometric method were tested on 56 women with PCOS (case group) and 41 healthy subjects (control group).
