Abstract
As a crucial economic trait, fat deposition is directly related to carcass quality and feed efficiency in sheep. The purpose of this study was to investigate the polymorphisms of the FGB gene related to fat deposition and detect the expression features of the FGB gene in different adipose tissues of sheep by using Sanger sequencing, MassARRAY® SNP technique, and quantitative real-time PCR (qRT-PCR). Results showed that in the intron region of the FGB gene, a SNP g. 3378953 A > T has been identified, and significant association was found between perirenal fat weight, perirenal fat relative weight, mesenteric fat weight, and mesenteric fat relative weight (P < 0.05). Moreover, qRT-PCR analysis showed that FGB was expressed in all three adipose tissues, and FGB gene expression level in the AA genotype was significantly lower than that in the AT or TT genotypes (P < 0.05). Therefore, the FGB gene can be used as a candidate gene to reduce fat deposition in Hu sheep breeding, and the selection of the AA genotype in Hu sheep in production practice is more conducive to improving production efficiency.

Abstract
OBJECTIVE Calcific aortic valve disease (CAVD) is the leading cause of angina, heart failure, and death from aortic stenosis. However, the molecular mechanisms of its progression, especially the complex disease-related transcriptional regulatory mechanisms, remain to be further elucidated. METHODS This study used porcine valvular interstitial cells (PVIC) as a model. We used osteogenic induced medium (OIM) to induce calcium deposition in PVICs to calcify them, followed by basic fibroblast growth factor (bFGF) treatment to inhibit calcium deposition. Transcriptome sequencing was used to study the mRNA expression profile of PVICs and its related transcriptional regulation. We used DaPars to further examine alternative polyadenylation (APA) between different treatment groups. RESULTS We successfully induced calcium deposition of PVICs through OIM. Subsequently, mRNA-seq was used to identify differentially expressed mRNAs for three different treatments: control, OIM-induced and OIM-induced bFGF treatment. Global APA events were identified in the OIM and bFGF treatment groups by bioinformatics analysis. Finally, it was discovered and proven that catalase (CAT) is one of the potential targets of bFGF-induced APA regulation. CONCLUSION We described a global APA change in a calcium deposition model related to CAVD. We revealed that transcriptional regulation of the CAT gene may contribute to bFGF-induced calcium deposition inhibition.

Abstract
BACKGROUND The aging process causes physiological changes on its own. The combination of an unhealthy lifestyle with the presence of genetic polymorphisms, such as the Val16Ala of the antioxidant enzyme manganese-dependent superoxide dismutase (MnSOD) may contribute to a greater occurrence of cardiometabolic risk factors. OBJECTIVE This study aimed to verify the association of Val16Ala-MnSOD polymorphism with food intake, caloric expenditure, and cardiometabolic risk factors in the elderly. METHODS A cross-sectional study with a sample size of 270 elderly individuals assisted in primary health care in the city of Porto Alegre, RS, Brazil. Val16Ala polymorphism, glucose, lipid profile, insulin, HOMA-IR, blood pressure, waist circumference, PCR-us, IL-6, food consumption, and caloric expenditure were evaluated. RESULTS The average age of the elderly was 68.6 ± 7.6 years. There were statistically significant differences regarding the consumption of two or more servings of fruits and vegetables daily between the elderly VV versus AV (P=0.017). There were also statistically significant differences regarding the consumption of two or more daily servings of legumes and eggs between the elderly AA versus VV (P=0.002). The median of insulin was higher in the elderly AA versus AV (P=0.025) and the median of HOMA-IR was higher in the elderly VV versus AV (P=0.029). AA elderly individuals had higher means of high-density lipoprotein (HDL-c) compared to AV (P=0.029). CONCLUSION The results suggest that Val16Ala -MnSOD polymorphism is associated with the consumption of fruits, vegetables, legumes, and eggs, as well as with cardiometabolic risk factors in the elderly.

Abstract
PURPOSE To clarify the role of Trp64Arg polymorphisms of the gene encoding the β3-adrenoceptor for lower urinary tract function in males, the present study investigated the association between the Trp64Arg polymorphisms and lower urinary tract symptoms (LUTS) and function. METHODS This prospective observational study included patients who underwent robot-assisted radical prostatectomy. Before surgery, blood samples were collected, and analyses of β3-adrenoceptor gene polymorphism were performed using the real-time polymerase chain reaction. The present cohort was divided into patients with wild type (Trp64Trp) and with variant type (Trp64Arg + Arg64Arg), and LUTS and lower urinary tract function before surgery were compared between them. RESULTS Wild type was found in 247 patients, with variant type in 129. There were no significant differences in LUTS between the two groups. Residual urine volume (PVR) (wild type: variant type = 47 ± 53 mL: 58 ± 77 mL, P = 0.04) and voiding time on uroflowmetry (wild type: variant type = 29 ± 15 s: 33 ± 17 s, P = 0.04) were significantly increased in the variant type. CONCLUSION The Trp64Arg variant of the β3-adrenoceptor gene significantly increased PVR and voiding time in men. However, it was not significantly associated with the emergence of LUTS. Thus, since the effect of β3-adrenoceptor gene polymorphisms on the genitourinary organs might be weak, whether men possess the Trp64Arg variant of the β3-adrenoceptor gene might not critically affect urinary quality of life, but modestly affect the lower urinary tract function.

Pharmacogenetic aspects of methotrexate in a cohort of Colombian patients with rheumatoid arthritis. Biomed Rep 2020; 13:34.

Abstract
Methotrexate (MTX) is the most commonly used disease-modifying antirheumatic drug for the treatment of rheumatoid arthritis (RA). However, over time, ~40% of patients may experience therapeutic failure or drug toxicity. The genetic variability of the enzymes involved in the MTX metabolic pathway seem to serve an important role in the eventual therapeutic failure or drug toxicity. Depending on the enzymes affected, the toxicity or the therapeutic response may change. The present study reports some of the polymorphisms identified in enzymes in the MTX metabolic pathway that are present in a group of Colombian patients with RA, and assesses the associations of these polymorphisms with toxicity or therapeutic response to the medication. A total of 400 patients with RA were evaluated, of which 76% were women. the average age was 60.7±13.9 years and the duration of the disease was 13.2±10.9 years. The disease activity scoring method, DAS28-CRP, was used to evaluate the therapeutic response. Toxicity was determined based on reports of adverse events during the evaluation of the patients. The single nucleotide polymorphisms (SNPs) assessed using reverse transcription-PCR in the present study were MTHFR C677T, A1298C, ATIC C347G, RFC-1-G80A, FPGS-AG and DHFR-CT. The SNPs of MTHFR C677T (P=0.05) and A1298C (P=0.048) were significantly associated with the efficacy of MTX, and DHFR-CT (P=0.01) and ATIC C347 (P=0.005) were significantly associated with documented toxicity. Haematological, hepatic or renal toxicity was not associated with any of the SNPs. The results obtained in Colombian patients with RA receiving MTX are similar to those reported in other populations; however, the SNPs associated with a lack of response previously reported in the literature were not observed in our data. The SNPs identified in the present study may be used as biomarkers to predict response to MTX in terms of efficacy and toxicity in Colombian patients with RA.

Abstract
Background Cardiovascular disease is the leading cause of death in postmenopausal women, and inflammation is a key mechanism involved in the pathogenesis of atherosclerosis. High-sensitivity C-reactive protein (hs-CRP) has been used as a biomarker of inflammation. Considering that CRP gene rs1205 polymorphism has been associated with hs-CRP circulating levels, we evaluated whether rs1205 genotypes influence the presence of low-grade chronic inflammation, acting as a marker of cardiovascular risk. Methods We performed a cross-sectional study with biobanked blood samples from 327 postmenopausal women with no evidence of clinical disease. Genotyping for rs1205 C > T SNP of the CRP gene was done by real-time polymerase chain reaction with allelic discrimination assays. Results Mean age was 55.6 ± 5.6 years. Mean body mass index (BMI) was 27.3 ± 4.7. Participants were divided according to hs-CRP levels: ≥3 mg/l (low-grade chronic inflammation) or < 3 mg/l. The frequency of allele C at rs1205 was 74.2% in the hs-CRP ≥ 3 mg/l group vs. 59% in the hs-CRP < 3 mg/l. In a multivariable model, higher prevalence of hs-CRP ≥ 3 mg/l was associated with CC genotype (PR 1.53; 95%CI 1.07-2.18; p = 0.018) and waist circumference ≥ 88 cm (PR 2.45; 95%CI 1.66-3.60; p < 0.001). Conclusions CRP rs1205 CC homozygotes may be at higher risk of a low-grade chronic inflammatory status compared to individuals carrying the T allele.

Abstract
OBJECTIVE The pathogenesis of depression is not fully understood yet, but studies have suggested higher circulating C reactive protein (CRP) level might relate to depression occurrence. However, due to high variability of patients' individual condition, the results to date are inconsistent. Considering CRP single-nucleotide polymorphisms (SNPs) could also regulate plasma CRP levels, in the present study, we hypothesized that inherited CRP allelic variations may co-vary with depressive symptomatology. METHODS We recruited 60 depression patients with family depression history and 60 healthy control volunteers into this project. We detected circulation CRP level as well as genome CRP SNPs from participants of this project. RESULTS We have found a significantly higher circulating CRP level in patients with a positive family history. Furthermore, we also identified some certain inherited CRP SNPs (A allele in rs1417938 and C allele in rs1205) could up regulate serum CRP level and distributed more in depression patients with family history. CONCLUSION Our finding may raise new evidence that genetically increased serum CRP level through SNPs variation is likely to induce family inherited depression.

Abstract
Preeclampsia is an inflammatory-mediated hypertensive disorder of pregnancy and seems to be an early indicator of increased cardiovascular risk, but mechanisms underlying this association are unclear. In this study, we identified levels of circulating inflammatory markers and dynamic changes in the systemic acute-phase response in 44 women with a history of severe early-onset preeclampsia, compared with 29 controls with only uneventful pregnancies at 1.5 to 3.5 years postpartum. Models used were in vivo seasonal influenza vaccination and in vitro whole-blood culture with T-cell stimulants and the toll-like receptor-4 ligand lipopolysaccharide. Outcome measures were C-reactive protein, interleukin-6 (IL-6), IL-18, fibrinogen, myeloperoxidase, and a panel of 13 cytokines representative of the innate and adaptive inflammatory response, in addition to established cardiovascular markers. The in vivo acute-phase response was higher for women with previous preeclampsia than that for controls without such a history, although only significant for C-reactive protein (P=0.04). Preeclampsia was associated with higher IL-1β (P<0.05) and IL-8 (P<0.01) responses to T-cell activation. Hierarchical clustering revealed 2 distinct inflammatory clusters associated with previous preeclampsia: an adaptive response cluster associated with increased C-reactive protein and IL-6 before and after vaccination, increased weight, and low high-density lipoprotein cholesterol; and a toll-like receptor-4 mediated the cluster associated with increased IL-18 before and after vaccination but not associated with other cardiovascular markers. Furthermore, we found interactions between previous preeclampsia, common TLR4 gene variants, and the IL-18 response to vaccination. In conclusion, preeclampsia is associated with alterations in the inflammatory response postpartum mostly independent of other established cardiovascular risk markers.

Abstract
It is widely acknowledged that cardiovascular heart disease (CHD) has a genetic influence. Several studies have investigated the role of inflammatory markers like C-reactive protein (CRP) and tumor necrosis factor α (TNF-α) in the causation of cardiovascular diseases. Although there have been several positive studies associating CRP and TNF-α genes with CHD, the evidence is not entirely consistent. Therefore, we performed a meta-analysis to gain a better understanding into this issue. The meta-analysis was conducted with 22 articles of genetic association studies of CRP (G1059C rs1800947, C1444T rs1130864, C717T rs2794521 and G3872A rs1205) and TNF-α (C857T rs1799724, C863A rs1800630 and T1031C rs1799964) genes. To analyze the association of these variants with CHD we used the following models: allelic, additive, dominant and recessive. In addition, we performed a sub-group analysis by Caucasian population using the same four models. CRP and TNF-α gene polymorphisms showed a positive significant association with CHD. This study provides evidence that rs2794521 of the CRP gene and rs1799724, rs1800630 and rs1799964 of the TNF-α gene polymorphisms may be risk factors to manifest CHD. The analysis of rs1800947 and rs1205 of the CRP gene yielded a protective effect in the pathogenesis of this disease. Only the analysis of the rs1130864 polymorphism showed a lack of association with CHD. To have conclusive outcomes it is necessary to integrate more studies to confirm our findings.

C-reactive protein gene variants: independent association with late-life depression and circulating protein levels. Transl Psychiatry 2015; 5:e499.

Abstract
C-reactive protein (CRP) is a heritable biomarker of systemic inflammation that is commonly elevated in depressed patients. Variants in the CRP gene that influence protein levels could thus be associated with depression but this has seldom been examined, especially in the elderly. Depression was assessed in 990 people aged at least 65 years as part of the ESPRIT study. A clinical level of depression (DEP) was defined as having a score of ⩾16 on The Center for Epidemiologic Studies Depression scale or a diagnosis of current major depression based on the Mini-International Neuropsychiatric Interview and according to Diagnostic and Statistical Manual of Mental Disorders-IV criteria. Five single-nucleotide polymorphisms spanning the CRP gene were genotyped, and circulating levels of high-sensitivity CRP were determined. Multivariable analyses adjusted for socio-demographic characteristics, smoking, ischemic pathologies, cognitive impairment and inflammation-related chronic pathologies. The minor alleles of rs1130864 and rs1417938 were associated with a decreased risk of depression in women at Bonferroni-corrected significance levels (P=0.002). CRP gene variants were associated with serum levels in a gender-specific manner, but only rs1205 was found to be nominally associated with both an increased risk of DEP and lower circulating CRP levels in women. Variants of the CRP gene thus influence circulating CRP levels and appear as independent susceptibility factors for late-life depression.

Abstract
OBJECTIVE Elevations in uric acid (UA) and the associated hyperuricaemia are commonly observed secondary to treatment with thiazide diuretics. We sought to identify novel single nucleotide polymorphisms (SNPs) associated with hydrochlorothiazide (HCTZ)-induced elevations in UA and hyperuricaemia. METHODS A genome-wide association study of HCTZ-induced changes in UA was performed in Caucasian and African American participants from the pharmacogenomic evaluation of antihypertensive responses (PEAR) study who were treated with HCTZ monotherapy. Suggestive SNPs were replicated in Caucasians and African Americans from the PEAR study who were treated with HCTZ add-on therapy. Replicated regions were followed up through expression and pathway analysis. RESULTS Five unique gene regions were identified in African Americans (LUC7L2, ANKRD17/COX18, FTO, PADI4 and PARD3B), and one region was identified in Caucasians (GRIN3A). Increases in UA of up to 1.8 mg dL(-1) were observed following HCTZ therapy in individuals homozygous for risk alleles, with heterozygotes displaying an intermediate phenotype. Several risk alleles were also associated with an increased risk of HCTZ-induced clinical hyperuricaemia. A composite risk score, constructed in African Americans using the 'top' SNP from each gene region, was strongly associated with HCTZ-induced UA elevations (P = 1.79 × 10(-7) ) and explained 11% of the variability in UA response. Expression studies in RNA from whole blood revealed significant differences in expression of FTO by rs4784333 genotype. Pathway analysis showed putative connections between many of the genes identified through common microRNAs. CONCLUSION Several novel gene regions were associated with HCTZ-induced UA elevations in African Americans (LUC7L2, COX18/ANKRD17, FTO, PADI4 and PARD3B), and one region was associated with these elevations in Caucasians (GRIN3A).

Abstract
OBJECTIVE C677T and A1298C polymorphisms in the enzyme methylenetetrahydrofolate reductase (MTHFR) have been associated with increased cardiovascular (CV) events in non-rheumatoid arthritis (RA) populations. We investigated potential associations of MTHFR polymorphisms and use of methotrexate (MTX) with time-to-CV event in data from the Veterans Affairs Rheumatoid Arthritis (VARA) registry. METHODS VARA participants were genotyped for MTHFR polymorphisms. Variables included demographic information, baseline comorbidities, RA duration, autoantibody status, and disease activity. Patients' comorbidities and outcome variables were defined using International Classification of Diseases-9 and Current Procedural Terminology codes. The combined CV event outcome included myocardial infarction (MI), percutaneous coronary intervention, coronary artery bypass graft surgery, and stroke. Cox proportional hazards regression was used to model the time-to-CV event. RESULTS Data were available for 1047 subjects. Post-enrollment CV events occurred in 97 patients (9.26%). Although there was a trend toward reduced risk of CV events, MTHFR polymorphisms were not significantly associated with time-to-CV event. Time-to-CV event was associated with prior stroke (HR 2.01, 95% CI 1.03-3.90), prior MI (HR 1.70, 95% CI 1.06-2.71), hyperlipidemia (HR 1.57, 95% CI 1.01-2.43), and increased modified Charlson-Deyo index (HR 1.23, 95% CI 1.13-1.34). MTX use (HR 0.66, 95% CI 0.44-0.99) and increasing education (HR 0.87, 95% CI 0.80-0.95) were associated with a lower risk for CV events. CONCLUSION Although MTHFR polymorphisms were previously associated with CV events in non-RA populations, we found only a trend toward decreased association with CV events in RA. Traditional risk factors conferred substantial CV risk, while MTX use and increasing years of education were protective.

Abstract
Paraoxonase 1 (PON1), a component of high-density lipoprotein (HDL), is a calcium-dependent multifunctional enzyme that connects metabolisms of lipoproteins and homocysteine (Hcy). Both PON1 and Hcy have been implicated in human diseases, including atherosclerosis and neurodegeneration. The involvement of Hcy in disease could be mediated through its interactions with PON1. Due to its ability to reduce oxidative stress, PON1 contributes to atheroprotective functions of HDL in mice and humans. Although PON1 has the ability to hydrolyze a variety of substrates, only one of them-Hcy-thiolactone-is known to occur naturally. In humans and mice, Hcy-thiolactonase activity of PON1 protects against N-homocysteinylation, which is detrimental to protein structure and function. PON1 also protects against neurotoxicity associated with hyperhomocysteinemia in mouse models. The links between PON1 and Hcy in relation to pathological states such as coronary artery disease, stroke, diabetic mellitus, kidney failure and Alzheimer's disease that emerge from recent studies are the topics of this review.

Abstract
PURPOSE Paraoxonase 1 (PON1) polymorphisms have been implicated as risk factors for coronary artery disease, but the results of genetic association studies on the related phenotype of ischemic stroke are inconclusive. We performed a meta-analysis of published studies investigating the association between ischemic stroke and two nonsynonymous PON1 polymorphisms, rs662 (p.Q192R) and rs854560 (p.L55M) in humans. METHODS We searched multiple electronic databases through June 30, 2009 for eligible studies. In main analyses, we calculated allele-based odds ratios with random effects models. In secondary analyses, we examined dominant and recessive genetic models as well, and performed subgroup and sensitivity analyses. RESULTS Regarding rs662, we identified 22 eligible studies (total of 7384 cases/11,074 controls), yielding a summary odds ratio of 1.10 per G allele (95% confidence interval, 1.04-1.17) with no evidence of between-study heterogeneity. For rs854560, 16 eligible studies (total of 5518 cases/8951 controls) yielded a summary odds ratio of 0.97 per T allele (95% confidence interval, 0.90-1.04), again with no evidence of between-study heterogeneity. For both polymorphisms, analyses with dominant and recessive genetic models yielded the same inferences as allele-based comparisons. Subgroup and sensitivity analyses showed similar results. CONCLUSION In agreement with observations in coronary artery disease, PON1 rs662 appears to be associated with a small increase in the risk of ischemic stroke.
