Sahin K, Rustemoglu A. Investigation of MIF gene promoter variations and their haplotypes in the Alzheimer disease in Turkish population. NUCLEOSIDES, NUCLEOTIDES & NUCLEIC ACIDS 2023; 43:277-291. [PMID: 37665108 DOI: 10.1080/15257770.2023.2253282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 02/28/2023] [Accepted: 08/24/2023] [Indexed: 09/05/2023]
Abstract
In Alzheimer's disease, which is characterized by amyloid plaques and neurofibrillary tangles in the brain tissue, many components such as acute phase proteins, cytokines, and proteases contribute to the progression of the disease or are part of the pathological process. The macrophage migration inhibitory factor (MIF) gene encodes a cytokine, which is secreted by lymphocytes, and has a role in the pathogenesis of autoimmune/inflammatory diseases such as rheumatoid arthritis. The purpose of this study to investigate the association between Alzheimer disease and MIF gene promoter polymorphisms. The 205 patients with Alzheimer disease (AD) and 130 age-sex matched healthy individuals were investigated in terms of MIF -173 G/C and MIF -794 CATT polymorphisms. The genotyping of MIF -173 G/C was determined using the RT-PCR method. MIF-794 CATT polymorphism was analyzed using PCR and DNA Sequencing. In terms of binary genotypes and haplotypes, the 5/5-GC (p = 0.004), 6/7-GG (p = 0.02) and, 6/6-GG (p = 0.026) binary genotypes, and 5-C (p = 0.003), 7-G (p = 0.026) and 6-G (p = 0.025) haplotypes were differed significantly between the patients and the controls. This is the first study investigating the relationship between AD and MIF in terms of different genotypes, haplotypes and, alleles. The fact that the binary genotype and allele distributions are significantly different between the patient and control group, suggests that this MIF variants may play a role in the pathogenesis of AD.

A pref-1-controlled non-inflammatory mechanism of insulin resistance. iScience 2023; 26:106923. [PMID: 37283810 PMCID: PMC10239698 DOI: 10.1016/j.isci.2023.106923] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 04/21/2023] [Accepted: 05/15/2023] [Indexed: 06/08/2023] Open
Abstract
While insulin resistance (IR) is associated with inflammation in white adipose tissue, we report a non-inflammatory adipose mechanism of high fat-induced IR mediated by loss of Pref-1. Pref-1, released from adipose Pref-1+ cells with characteristics of M2 macrophages, endothelial cells or progenitors, inhibits MIF release from both Pref-1+ cells and adipocytes by binding with integrin β1 and inhibiting the mobilization of p115. High palmitic acid induces PAR2 expression in Pref-1+ cells, downregulating Pref-1 expression and release in an AMPK-dependent manner. The loss of Pref-1 increases adipose MIF secretion contributing to non-inflammatory IR in obesity. Treatment with Pref-1 blunts the increase in circulating plasma MIF levels and subsequent IR induced by a high palmitic acid diet. Thus, high levels of fatty acids suppress Pref-1 expression and secretion, through increased activation of PAR2, resulting in an increase in MIF secretion and a non-inflammatory adipose mechanism of IR.

Abstract
The main functions of adipose tissue are thought to be storage and mobilization of the body’s energy reserves, active and passive thermoregulation, participation in the spatial organization of internal organs, protection of the body from lipotoxicity, and ectopic lipid deposition. After the discovery of adipokines, the endocrine function was added to the above list, and after the identification of crosstalk between adipocytes and immune cells, an immune function was suggested. Nonetheless, it turned out that the mechanisms underlying mutual regulatory relations of adipocytes, preadipocytes, immune cells, and their microenvironment are complex and redundant at many levels. One possible way to elucidate the picture of adipose-tissue regulation is to determine genetic variants correlating with obesity. In this review, we examine various aspects of adipose-tissue involvement in innate immune responses as well as variants of immune-response genes associated with obesity.

Abstract
Background The macrophage migration inhibiting factor (MIF) is a protein that promotes the activation of immune cells and the production of other proinflammatory cytokines such as TNF‐α, IL‐1β, and IFN‐γ, which have proposed to play an essential role in the pathogenesis of vitiligo. The study aimed to assess the association between MIF polymorphisms (−794 CATT5‐8 and −173 G>C), MIF in situ expression, and MIF serum concentrations with susceptibility and disease activity in patients with non‐segmental vitiligo (NSV) from western Mexico. Methods The study included 111 patients with NSV and 201 control subjects. Genotyping was performed by conventional PCR (−794 CATT5‐8) and PCR‐RFLP (−173 G>C) methods. MIF mRNA expression was quantified by real‐time PCR and MIF serum concentrations were determined by ELISA kit. Histopathological samples were analyzed by automated immunohistochemistry. Results The MIF polymorphisms were associated with NSV susceptibility. Serum concentrations of MIF were higher in patients with active NSV and correlated negatively with the years of evolution. The depigmented skin from patients with active vitiligo showed a high expression of MIF. Conclusion MIF polymorphisms increase the risk of NSV in the western Mexican population. The serum concentrations of MIF and in situ expression are associated with active NSV.

Abstract
OBJECTIVE Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine secreted by macrophages. This study is performed to investigate whether serum MIF is correlated with atrial fibrillation (AF). METHODS Totally, 186 AF patients and 103 healthy controls were enrolled in this study. AF patients were then divided into paroxysmal AF, persistent AF, and permanent AF subgroups. RESULTS There were higher serum MIF concentrations in AF patients than in healthy subjects. Logistic regression analysis demonstrated that serum MIF was associated with AF. Permanent AF patients exhibited higher serum MIF concentrations than persistent and paroxysmal AF subgroups. Elevated serum MIF concentrations were found in persistent AF patients compared with paroxysmal AF patients. Moreover, serum MIF concentrations were associated with left atrial diameter after Spearman correlation analysis.

Abstract
The rising number of obese individuals has become a major burden to the healthcare systems worldwide. Obesity includes not only the increase of adipose tissue mass but importantly also the altered cellular functions that collectively lead to a chronic state of adipose tissue inflammation, insulin resistance and impaired wound healing. Adipose tissue undergoing chronic inflammation shows altered cytokine expression and an accumulation of adipose tissue macrophages (ATM). The macrophage migration inhibitory factor (MIF) superfamily consists of MIF and the recently identified homolog D-dopachrome tautomerase (D-DT or MIF-2). MIF and D-DT, which both bind to the CD74/CD44 receptor complex, are differentially expressed in adipose tissue and have distinct roles in adipogenesis. MIF positively correlates with obesity as well as insulin resistance and contributes to adipose tissue inflammation by modulating ATM functions. D-DT, however, is negatively correlated with obesity and reverses glucose intolerance. In this review, their respective roles in adipose tissue homeostasis, adipose tissue inflammation, insulin resistance and impaired wound healing will be reviewed.

Abstract
We analyzed the relationship of −794 CATT5–8 and −173 G>C MIF polymorphisms with mRNA and soluble MIF in young obese subjects. A total of 250 young subjects, 150 normal-weight and 100 obese subjects, were recruited in the study. Genotyping of −794 CATT5–8 and −173 G>C MIF polymorphisms was performed by PCR and PCR-RFLP, respectively. MIF mRNA expression was determined by real-time PCR and serum MIF levels were measured using an ELISA kit. For both MIF promoter polymorphisms, no significant differences in the genotype and allele frequencies between groups were observed. MIF mRNA expression was slightly higher in obese subjects than in normal-weight subjects (1.38-fold), while soluble MIF levels did not show differences between groups. In addition, we found an increase in MIF mRNA expression in carriers of the 6,6 and C/C genotypes and the 6G haplotype of the −794 CATT5–8 and −173 G>C MIF polymorphisms, although it was not significant. In conclusion, this study found no relationship between obesity and MIF gene promoter polymorphisms with MIF mRNA expression in young obese subjects.

Abstract
The cytokine “macrophage migration inhibitory factor (MIF)” is generally recognized as a proinflammatory cytokine, and MIF is involved in broad range of acute and chronic inflammatory states. With regard to glucose metabolism and insulin secretion, MIF is produced by pancreatic β cells and acts as a positive regulator of insulin secretion. In contrast, it is evident that MIF expressed in adipose tissues causes insulin resistance. Concerning MIF gene analysis, we found four alleles: 5-, 6-, 7-and 8-CATT at position −794 of MIF gene in a Japanese population. Genotypes without the 5-CATT allele were more common in the obese subjects than in the lean or overweight groups. It is conceivable that promoter polymorphism in the MIF gene is profoundly linked with obesity relevant to lifestyle diseases, such as diabetes. Obesity has become a serious social issue due to the inappropriate nutritional balance, and the consumption of functional foods (including functional foods to reduce fat mass) is expected to overcome this issue. In this context, MIF would be a reliable quantitative biomarker to evaluate the effects of functional foods on adiposity.

Abstract
AIM: To investigate the association of macrophage migration inhibitory factor (MIF) promoter polymorphisms with inflammatory bowel disease (IBD) risk.
METHODS: One thousand and six New Zealand Caucasian cases and 540 Caucasian controls were genotyped for the MIF SNP -173G > C (rs755622) and the repeat polymorphism CATT5-8 (rs5844572) using a pre-designed TaqMan SNP assay and capillary electrophoresis, respectively. Data were analysed for single site and haplotype association with IBD risk and phenotype. Meta-analysis was employed, to assess cumulative evidence of association of MIF -173G > C with IBD. All published genotype data for MIF -173G > C in IBD were identified using PubMed and subsequently searching the references of all PubMed-identified studies. Imputed genotypes for MIF -173G > C were generated from the Wellcome Trust Case Control Consortium (and National Institute of Diabetes and Digestive and Kidney Diseases). Separate meta-analyses were performed on Caucasian Crohn’s disease (CD) (3863 patients, 6031 controls), Caucasian ulcerative colitis (UC) (1260 patients, 1987 controls), and East Asian UC (416 patients and 789 controls) datasets using the Mantel-Haenszel method. The New Zealand dataset had 93% power, and the meta-analyses had 100% power to detect an effect size of OR = 1.40 at α = 0.05, respectively.
RESULTS: In our New Zealand dataset, single-site analysis found no evidence of association of MIF polymorphisms with overall risk of CD, UC, and IBD or disease phenotype (all P values > 0.05). Haplotype analysis found the CATT5/-173C haplotype occurred at a higher frequency in New Zealand controls compared to IBD patients (0.6 vs 0.01; P = 0.03, OR = 0.22; 95%CI: 0.05-0.99), but this association did not survive bonferroni correction. Meta-analysis of our New Zealand MIF -173G > C data with data from seven additional Caucasian datasets using a random effects model found no association of MIF polymorphisms with CD, UC, or overall IBD. Similarly, meta-analysis of all published MIF -173G > C data from East Asian datasets (416 UC patients, 789 controls) found no association of this promoter polymorphism with UC.
CONCLUSION: We found no evidence of association of MIF promoter polymorphisms with IBD.

Abstract
Macrophage migration inhibitory factor (MIF) is a unique protein that participates in inflammation, immune responses, and cell growth. An array of in vitro and in vivo experiments has demonstrated that MIF is profoundly involved in the pathogenesis of acute and chronic inflammatory disorders, such as inflammatory bowel disease (IBD). Blockade of MIF bioactivities by either neutralizing anti-MIF antibodies or antagonists prevents inflammatory cytokine cascade, which strongly suggests that an anti-MIF therapeutic strategy is feasible for treatment of IBD. Recently, we developed a new therapeutic approach for IBD by administration of antisense MIF oligonucleotides in conjugation with schizophyllan (SPG), a member of the glucan family. SPG specifically binds Dectin-1 expressed in antigen-presenting cells (APCs), and the antisense MIF/SPG complex is incorporated into the cells. In in vivo experiments of colitis models in mice, we found that intraperitoneal administration of the complex ameliorated the clinical signs of colitis and improved the histological scores. This novel therapy designed to knock down the MIF production in APCs is expected to be clinically applicable for the treatment of IBD.

Abstract
INTRODUCTION Obstructive sleep apnea (OSA) is associated with increased risk for cardiovascular and metabolic dysfunction in both adults and children. In adults with OSA, serum levels of macrophage migration inhibitory factor (MIF) are elevated. Therefore, we assessed plasma MIF levels and MIF allelic variant frequencies in children with and without OSA (NOSA). METHODS A total of 614 consecutive children ages 5-8 years were recruited. Children were divided into those with OSA and NOSA based on the apnea-hypopnea index (AHI). In addition to lipid profile, hsCRP, and fasting insulin and glucose levels, plasma MIF levels were assayed using ELISA, and 28 single nucleotide polymorphisms (SNPs) covering the region were genotyped. Linkage disequilibrium and haplotype blocks were analyzed using Haploview version 4.2 software. RESULTS Morning plasma MIF levels were increased in children with OSA. Of the 28 SNPs tested, the frequency of rs10433310 minor allele was significantly decreased in OSA. This SNP was also associated with reduced fasting insulin and hsCRP levels in OSA. The minor allele frequency of all other 27 SNPs was similar in OSA and NOSA groups. CONCLUSIONS Childhood OSA is associated with higher plasma MIF, hsCRP, and fasting insulin levels that promote cardiometabolic risk, and the MIF gene SNP rs10433310 may account for some of the variance in such risk.

Abstract
High-fat diet (HFD)-induced obesity has emerged as a state of chronic low-grade inflammation characterised by a progressive infiltration of immune cells, particularly macrophages, into obese adipose tissue. Adipose tissue macrophages (ATM) present immense plasticity. In early obesity, M2 anti-inflammatory macrophages acquire an M1 pro-inflammatory phenotype. Pro-inflammatory cytokines including TNF-α, IL-6 and IL-1β produced by M1 ATM exacerbate local inflammation promoting insulin resistance (IR), which consequently, can lead to type-2 diabetes mellitus (T2DM). However, the triggers responsible for ATM recruitment and activation are not fully understood. Adipose tissue-derived chemokines are significant players in driving ATM recruitment during obesity. Macrophage migration inhibitory factor (MIF), a chemokine-like inflammatory regulator, is enhanced during obesity and is directly associated with the degree of peripheral IR. This review focuses on the functional role of macrophages in obesity-induced IR and highlights the importance of the unique inflammatory cytokine MIF in propagating obesity-induced inflammation and IR. Given MIF chemotactic properties, MIF may be a primary candidate promoting ATM recruitment during obesity. Manipulating MIF inflammatory activities in obesity, using pharmacological agents or functional foods, may be therapeutically beneficial for the treatment and prevention of obesity-related metabolic diseases.

Abstract
OBJECTIVE To compare the resting energy expenditure in different macrophage migration inhibitory factor (MIF) genotypes and to identify the in vitro effects of Alpinia officinarum Hance extract (AOHE) on MIF expression in obese and nonobese persons. METHODS In the fasting state, obese and nonobese persons were assessed for the measurement of resting energy expenditure rate (REE) by indirect calorimetry. We compared it with the expected amount ([REE measured by indirect calorimetry / predicted REE according to Harris Benedict equations] x 100). Participants were classified into those with normal REE (≥100) vs those with impaired REE (<100). Body composition was analyzed. Real-time polymerase chain reaction was performed using specific primer pairs for MIF messenger RNA, and β-actin was used as the internal control. RESULTS The study included 69 obese and 103 non-obese participants. The proportions of MIF genotypes were slightly different in obese and nonobese participants. However, the proportions of MIF genotypes were significantly different in participants with normal REE and those with low REE. The MIF gene was highly expressed in the obese group compared with MIF expression in the nonobese group. Body fat mass and MIF expression were higher in participants with the GG genotype than in the other genotype groups. MIF expression was inversely associated with REE in both groups (r = -0.36, P = .04). After treatment of peripheral blood mononuclear cells with AOHE, MIF expression differed according to MIF genotype. CONCLUSIONS Our results indicate that AOHE is a major modulator of MIF-dependent pathologic conditions in obesity and are consistent with mounting evidence that defines a regulating role for MIF in cytokine production in an inflammatory state in in vitro studies.

Abstract
Macrophage migration inhibitory factor (MIF) is a pleiotropic proinflammatory cytokine that has been implicated as playing a causative role in many disease states, including sepsis, pneumonia, diabetes, rheumatoid arthritis, inflammatory bowel disease, psoriasis and cancer. To inhibit the enzymatic and biologic activities of MIF, we and others have developed small-molecule MIF inhibitors. Most MIF inhibitors bind within the hydrophobic pocket that contains highly conserved amino acids known to be essential for MIF's proinflammatory activity. The best characterized of these small-molecule MIF inhibitors, (S,R)-3-(4-hydroxyphenyl)-4,5-dihydro-5-isoxazole acetic acid methyl ester (ISO-1) has been validated in scores of laboratories worldwide. Like neutralizing anti-MIF antibodies, ISO-1 significantly improves survival and reduces disease progression and/or severity in multiple murine models where MIF is implicated. This MIF inhibitor, its derivatives and other MIF-targeted compounds show great promise for future testing in disease states where increased MIF activity has been discovered.

Abstract
Previous investigations have demonstrated the association of the CATT repeated allele in the Macrophage migration inhibitory factor (MIF) with obesity and diabetes. Since there are common risk factors and molecular pathways in Type 2 Diabetes and Gestational Diabetes Mellitus (GDM), we focused on the associations of MIF variation with GDM. In a case-control study we enrolled 157 GDM and 217 healthy pregnant women, referred to the outpatient clinic of Shariati Hospital. The different repeats of CATT in MIF promoter were determined. MIF relative gene expression was evaluated in Peripheral blood mononuclear cells of all the participants. The GDM group had higher mean age and pre-gravid BMI. Also fasting serum glucose, insulin and MIF gene expression were significantly higher in the GDM patients. The statistically significant difference was observed between GDM and a healthy group in carrying 7-CATT allele and MIF gene expression. Regarding GDM risk factors, MIF 7-CATT allele showed significant relation with pre-pregnancy obesity, as well as the need for insulin therapy. Our results indicate that an association between MIF genotypes and its expression with GDM, obesity and the need of insulin for management of GDM patients exists.

Abstract
Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine involved in the pathogenesis of a variety of autoimmune inflammatory diseases. Here, we investigated the role of MIF in the pathogenesis of non-insulin-dependent diabetes mellitus (NIDDM) using MIF(-/-) mice and a mouse model of streptozotocin (STZ)-induced NIDDM. Following single injection of STZ, MIF(+/+) BALB/c mice showed a significant increase in blood glucose levels, developed polyuria, and succumbed to disease. In contrast, no such increase in blood glucose was observed in MIF(-/-) BALB/c mice treated with STZ. These mice produced significantly less inflammatory cytokines and resistin as compared with MIF(+/+) mice and failed to develop clinical disease. Finally, oral administration of a small-molecule MIF antagonist, CPSI-1306, to outbred ICR mice following induction of NIDDM significantly lowered blood glucose levels in the majority of animals, which was also associated with a significant reduction in the levels of the proinflammatory cytokines IL-6 and TNF-alpha in the sera. Taken together, these results demonstrate that MIF is involved in the pathogenesis of NIDDM and is a therapeutic target to treat this disease.

Abstract
Obesity is associated with insulin resistance, disturbed glucose homeostasis, low grade inflammation, and comorbidities such as type 2 diabetes and cardiovascular disease. The cytokine macrophage migration inhibitory factor (MIF) is an ubiquitously expressed protein that plays a crucial role in many inflammatory and autoimmune disorders. Increasing evidence suggests that MIF also controls metabolic and inflammatory processes underlying the development of metabolic pathologies associated with obesity. This is a comprehensive summary of our current knowledge on the role of MIF in obesity and obesity-associated comorbidities, based on human clinical data as well as animal models of disease.

Abstract
AIMS Macrophage migration inhibitory factor (MIF) is a potent pro-inflammatory cytokine whose production is transcriptionally regulated by glucose. Experimental data from both Type 1 diabetes mellitus (T1D) patients and animal models suggests a role for MIF in the development of T1D. The aim of this study was to employ gene resequencing to identify common DNA polymorphisms in the MIF gene and subsequently assess haplotype tagged single nucleotide polymorphisms (htSNPs) using a combination of case-control and family-based association analyses in order to assess the association of MIF htSNPs with the development of T1D in a white population. METHODS All exons, introns and approximately 3 kb upstream and downstream of the MIF gene were screened for DNA polymorphisms in 46 individuals using DNA sequencing. Genotyping of the htSNPs was performed in 432 cases, 407 control subjects and 290 T1D parent-offspring trios, using Taqman, Sequenom, Pyrosequencing and fluorescence-based microsatellite technologies. RESULTS Twenty-three polymorphisms (two novel) with a minor allele frequency > 10% were identified. Four MIF htSNPs (rs875643 G>A, rs7388067 C>T, rs5844572 -/CATT, rs6003941 T>G) were identified. Allele and haplotype frequencies were similar between case and control groups (P > 0.6 by permutation test) and assessment of allele transmission distortion from informative parents to affected offspring also failed to find an association. Stratification of these analyses for age-at-onset and human leukocyte antigen (HLA)-DR risk group (DR3/DR4) did not reveal any significant associations. CONCLUSIONS It is unlikely that common polymorphisms in the MIF gene strongly influence susceptibility to T1D in the UK population.

Abstract
Obesity is a condition in which adipose tissue mass is expanded. Increases in both adipocyte size and number contribute to enlargement of adipose tissue. The increase in cell number is thought to be caused by proliferation and differentiation of preadipocytes. Macrophage migration inhibitory factor (MIF) is expressed in adipocytes, and intracellular MIF content is increased during adipogenesis. Therefore, we hypothesized that MIF is associated with adipocyte biology during adipogenesis and focused on the influence of MIF on adipogenesis. To examine the effects of MIF on adipocytes, MIF expression in 3T3-L1 preadipocytes was inhibited by RNA interference, and cell differentiation was induced by standard procedures. The triglyceride content of MIF small interfering RNA (siRNA)-transfected 3T3-L1 cells was smaller than that of nonspecific siRNA-transfected cells. In addition, MIF knockdown apparently abrogated increases in adiponectin mRNA levels during differentiation. Gene expression of peroxisome proliferator-activated receptor (PPAR)gamma, CCAAT/enhancer binding protein (C/EBP)alpha, and C/EBPdelta decreased with MIF siRNA transfection, but C/EBPbeta expression increased. Cell number and incorporation of 5-bromo-2-deoxyuridine into cells decreased from 1-3 d and from 14-20 h, respectively, after induction of differentiation in MIF siRNA-transfected cells, thus suggesting that MIF siRNA inhibits mitotic clonal expansion. Taken together, these results indicated that MIF regulates differentiation of 3T3-L1 preadipocytes, at least partially, through inhibition of mitotic clonal expansion and/or C/EBPdelta expression.

Abstract
OBJECTIVE To compare the concentrations of cytokines belonging to Th17 axis (interleukin (IL)-17 and IL-23) and Th1 axis (IL-12 and interferon (IFN)-gamma) in obese and lean women, and to investigate their relationships with the proinflammatory adipokine leptin, proinflammatory cytokine macrophage migration inhibitory factor (MIF) and anthropometric and metabolic parameters of obesity. DESIGN Cross-sectional study. SUBJECTS Twenty-six obese women (age 20-52 years, body mass index (BMI): 30-48 kg/m(2)) and 20 healthy lean women (age 23-46 years, BMI: 18-25 kg/m(2)). MEASUREMENTS Plasma levels of cytokines and leptin, BMI, waist circumference (WC) and insulin resistance index HOMA (homeostatic model assessment). RESULTS Blood concentrations of IL-17, IL-23, MIF and leptin, but not IL-12 or IFN-gamma, were higher in obese compared with lean women (P=0.002, 0.046, 0.006 and 0.002, respectively). There was a positive correlation between IL-17 and IL-23 (r(s)=0.530), which was at the border of statistical significance (P=0.065). Neither IL-17 nor IL-23 correlated with leptin or MIF, and there was no association between IL-17 and IL-23 levels with BMI, WC or HOMA index. CONCLUSION Interleukin-23/IL-17 axis is stimulated in obese women independently of the increase in abdominal fat, insulin resistance, leptin and MIF levels.

Abstract
Macrophage migration inhibitory factor (MIF) is a proinflammatory cytokine involved in many inflammatory reactions and disorders, and it has become evident that it also affects glucose homeostasis. The protein is produced by pancreatic beta cells and can promote the release of insulin. It also modulates glucose uptake, glycolysis and insulin resistance in insulin target cells such as the adipocyte, myocyte and cardiomyocyte. Possessing both immunological and endocrinological properties, MIF has been associated with the development of type 1 and type 2 diabetes, and it may be important in the setting of islet transplantation. The present review summarises our current knowledge, based on clinical and research data, on the impact of MIF on both physiological and pathological aspects of glucose metabolism.

Abstract
AIMS/HYPOTHESIS Macrophage migration inhibitory factor (MIF) is a central mediator of innate immunity. Our aim was to investigate the triangular association between MIF genotypes, circulating MIF concentrations and incident type 2 diabetes, and to use a Mendelian randomisation approach to assess the causal role of MIF. METHODS Using a case-cohort design within the population-based MONICA/KORA Augsburg Study, based on 502 individuals with incident type 2 diabetes (293 men, 209 women) and 1,632 non-cases (859 men, 773 women), we determined MIF serum levels at baseline and genotyped four MIF single nucleotide polymorphisms (SNPs). RESULTS The C allele of SNP rs1007888 (3.8 kb 3' of the translation termination codon) was associated with increased circulating MIF. MIF genotype rs1007888CC was associated with an increased risk of type 2 diabetes in women [hazard ratio (95% CI) 1.74 (1.02-2.97)], but not in men [1.17 (0.75-1.81)]. Elevated MIF serum levels were associated with higher type 2 diabetes risk also only in women [HR (95% CI) 1.95 (1.15-3.29) comparing extreme quartiles after multiple adjustment], but not in men (p for interaction 0.039). The association between MIF levels and incident type 2 diabetes was significantly higher in obese women (111 cases, 147 non-cases) compared with non-obese women (98 cases, 626 non-cases; p for BMI interaction 0.0002). CONCLUSIONS/INTERPRETATION The consistent triangular relationship between genotypes, serum levels and incident type 2 diabetes in women indicates that MIF may play a causal role in the aetiology of type 2 diabetes and that elevated MIF levels confer a higher disease risk.
