Abstract
OBJECTIVE Axitinib is an oral multi-target tyrosine kinase inhibitor used for the treatment of renal cell carcinoma (RCC). Because of the severe adverse events (AEs) associated with axitinib, patients often need dose reductions or discontinue its use, highlighting the need for effective biomarkers to assess efficacy and/or AEs. The aim of this study was to investigate the relationship between single nucleotide polymorphisms (SNPs) in genes involved in the pharmacodynamic action of axitinib and clinical prognosis and AEs in metastatic RCC (mRCC) patients. METHODS This study included 80 mRCC patients treated with first-, second-, or third-line axitinib (5 mg orally twice daily). Clinical parameters and genetic polymorphisms were examined in 75 cases (53 males and 22 females). We assessed three SNPs in each of three candidate genes namely, angiotensin-converting enzyme (ACE), nitric oxide synthase 3 (NOS3), and angiotensin II receptor type 1 (AT1R), all of which are involved in axitinib effects on vascular endothelial function. RESULTS Axitinib-treated patients carrying the ACE deletion allele suffered more frequently from hand-foot syndrome and a deterioration in kidney function (p = .045 and p = 0.005, respectively) whereas those carrying the NOS3 G allele suffered more frequently from proteinuria and multiple AEs (p = .025 and p = 0.036, respectively). CONCLUSIONS Our study found that the ACE deletion allele and the NOS3 G allele are associated with increased AEs.

A role for endothelial NMDA receptors in the pathophysiology of schizophrenia. Schizophr Res 2022; 249:63-73. [PMID: 33189520 DOI: 10.1016/j.schres.2020.10.004] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2019] [Revised: 10/05/2020] [Accepted: 10/07/2020] [Indexed: 12/14/2022]
Abstract
Numerous genetic and postmortem studies link N-methyl-d-aspartate receptor (NMDAR) dysfunction with schizophrenia, forming the basis of the popular glutamate hypothesis. Neuronal NMDAR abnormalities are consistently reported from both basic and clinical experiments, however, non-neuronal cells also contain NMDARs, and are rarely, if ever, considered in the discussion of glutamate action in schizophrenia. We offer an examination of recent discoveries elucidating the actions and consequences of NMDAR activation in the neuroendothelium. While there has been mixed literature regarding blood flow alterations in the schizophrenia brain, in this review, we posit that some common findings may be explained by neuroendothelial NMDAR dysfunction. In particular, we emphasize that endothelial NMDARs are key mediators of neurovascular coupling, where increased neuronal activity leads to increased blood flow. Based on the broad conclusions that hypoperfusion is a neuroanatomical finding in schizophrenia, we discuss potential mechanisms by which endothelial NMDARs contribute to this disorder. We propose that endothelial NMDAR dysfunction can be a primary cause of neurovascular abnormalities in schizophrenia. Importantly, functional MRI studies using BOLD signal as a proxy for neuron activity should be considered in a new light if neurovascular coupling is impaired in schizophrenia. This review is the first to propose that NMDARs in non-excitable cells play a role in schizophrenia.

Abstract
The high prevalence of metabolic syndrome in persons with schizophrenia has spurred investigational efforts to study the mechanism beneath its pathophysiology. Early psychosis dysfunction is present across multiple organ systems. On this account, schizophrenia may be a multisystem disorder in which one organ system is predominantly affected and where other organ systems are also concurrently involved. Growing evidence of the overlapping neurobiological profiles of metabolic risk factors and psychiatric symptoms, such as an association with cognitive dysfunction, altered autonomic nervous system regulation, desynchrony in the resting-state default mode network, and shared genetic liability, suggest that metabolic syndrome and schizophrenia are connected via common pathways that are central to schizophrenia pathogenesis, which may be underpinned by oxytocin system dysfunction. Oxytocin, a hormone that involves in the mechanisms of food intake and metabolic homeostasis, may partly explain this piece of the puzzle in the mechanism underlying this association. Given its prosocial and anorexigenic properties, oxytocin has been administered intranasally to investigate its therapeutic potential in schizophrenia and obesity. Although the pathophysiology and mechanisms of oxytocinergic dysfunction in metabolic syndrome and schizophrenia are both complex and it is still too early to draw a conclusion upon, oxytocinergic dysfunction may yield a new mechanistic insight into schizophrenia pathogenesis and treatment.

Nguyen HD, Kim MS. The protective effects of curcumin on metabolic syndrome and its components: In-silico analysis for genes, transcription factors, and microRNAs involved. Arch Biochem Biophys 2022; 727:109326. [PMID: 35728632 DOI: 10.1016/j.abb.2022.109326] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 05/04/2022] [Accepted: 06/16/2022] [Indexed: 11/18/2022]
Abstract
BACKGROUND We aimed to identify the molecular mechanisms behind curcumin's therapeutic benefits for metabolic syndrome (MetS) and its components. METHODS The Comparative Toxicogenomics Database, MIENTURNET, Metascape, GeneMania, and Cytoscape software were critical analytic tools. RESULTS Curcumin may have therapeutic effects on MetS and its components via the following genes: NOS3, IL6, INS, and ADIPOQ, particularly PPARG. Curcumin has higher docking scores than other genes with INS and PPARG (docking scores: -8.3 and -5.8, respectively). Physical interactions (56%) were found to be the most prevalent for dyslipidemia, co-expression for hypertension, obesity, T2DM, and MetS. "Galanin receptor pathway", "lipid particles composition", "IL-18 signaling pathway", "response to extracellular stimulus", and "insulin resistance" were listed in the first of the key pathways for MetS, dyslipidemia, hypertension, obesity, and diabetes, respectively. The protein-protein interaction enrichment analysis study also identified "vitamin B12 metabolism," "folate metabolism," and "selenium micronutrient network" as three major molecular pathways linked to MetS targeted by curcumin. PPARG was the key transcription factor that regulated practically all curcumin-targeted genes linked to MetS and its components. Curcumin targeted hsa-miR-155-5p, which has been linked to T2DM, hypertension, and MetS, as well as hsa-miR-130b-3p and hsa-miR-22-3p, which have been linked to dyslipidemia and obesity, respectively. In silico, sponges that regulated hsa-miR-155-5p were developed and evaluated. Curcumin, MetS, and its components have been found to target adipocytes, cardiac myocytes, smooth muscle, the liver, and pancreas. Curcumin's physicochemical properties and pharmacokinetics are closely connected with its therapeutic advantages in MetS and its components due to its high gastrointestinal absorption, drug-likeness, water solubility, and lipophilic nature. Curcumin is a CYP1A9 and CYP3A4 inhibitor. Although curcumin has a low bioavailability, it can be synthesized and administered to increase its pharmacokinetic features. CONCLUSIONS Curcumin needs to undergo therapeutic optimization and further study into its pharmacological structure before it can be used to treat MetS and its components.

Risks’ Stratification of Metabolic Disorders and Arterial Hypertension Depending on the NOS3 (RS2070744) and GNB3 (RS5443) Genes’ Allelic State. Fam Med 2022. [DOI: 10.30841/2307-5112.1-2.2022.260501] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/18/2022]
Abstract
Early diagnosis of essential arterial hypertension (EAH), the search for risk factors for its occurrence and severity, which determine the metabolome and epigenetic structures activity, is an urgent task of modern medicine.
The objective: to assess the risks of metabolic disorders and the EAH occurrence, depending on the NOS3 (rs2070744) and GNB3 (rs5443) genes’ allelic state.
Materials and methods. 100 patients with EAH and 48 practically healthy (control group) were enrolled in the study. All participant underwent clinical and laboratory examinations. Metabolic changes were examined by blood glucose, total cholesterol (TC), triacylglycerol (TG), high and low density lipoprotein cholesterol (HDL-C, LDL-C), Atherogenicity index (AI). The NOS3 (rs2070744) and GNB3 (rs5443) genes were studied by real-time PCR. Risks, prognoses were determined by the clinical epidemiology method.
Results. The risk of metabolic disorders (dyslipidemia and hyperglycemia) in EAH patients does not depend on NOS3 gene polymorphism (rs2070744). However, the mutational T-allele of the GNB3 gene (825C>T) presence in the patients’ genotype increases the risk of hyperlipidemia due to atherogenic LDL-C 8.5 times [OR=8.45; OR 95%CI:0.99–72.70; p=0.05], with the CC-genotype protective role [OR=0.12; OR 95%CI:0.01–1.0; p=0.048].
The overall risk of EAH in the examined population increases with fasting hyperglycemia 9 times [OR 95%CI:2.86–27.08; p<0.001], with hypertriglyceridemia (>1.70 mmol/l) – 3 times [OR 95%CI:1.23–5.56; p=0.009] and with a decrease in HDL-C (<1.2 mmol/l) – more than 3.5 times [OR 95%CI:1.46–8.71; p=0.003], respectively.
Conclusion. The risk of metabolic disorders increases in EAH patients with the T-allele of the GNB3 gene (825C>T) 8.5 times with the lowest probability of such changes in the CC-genotype carriers [OR=0.12; p=0.048].

Abstract
OBJECTIVE The aim: To determine the association between the Glu298Asp (G894T) polymorphisms of the eNOS gene with metabolic disorders in excessive gestational weight gain (GWG) pregnancy. PATIENTS AND METHODS Materials and methods: 97 pregnant women in 9-12, and 37-39 weeks of gestation were examined. The recommended GWG was diagnosed in 33 (34.0 %), insufficient in 19 (19.6 %), and excessive in 45 (46.4 %) patients. Genetic variants of eNOS were analyzed by real-time polymerase chain reaction, lipid profile, and carbohydrate status were performed. The results were statistically analyzed using Statistica 6.0 program pack (StatSoft Inc., USA) and Microsoft Excel statistical analysis package. RESULTS Results: GWG in the group of patients with gene eNOS TT polymorphism was significantly higher (1.5-fold) compared to pregnant with GG - genotype (р<0.05). Pregnant, inherited the TT allele of the eNOS gene, associated with higher levels of hypertriglyceridemia, hypercholesterolemia, of lipoprotein low density, glycemia, hyperinsulinemia, and higher HOMA-IR compared to carriers of GG and GT alleles (р<0.05) in the third trimester, which is especially manifested in excessive GWG. CONCLUSION Conclusions: Decreased activity of the eNOS gene in the presence of pathological alleles is the initiator of impaired lipid and carbohydrate metabolisms and, as a consequence, excessive GWG. A high risk of excessive GWG was found in pregnant women with TT polymorphism Glu298Asp (G894T) (OR=4.52; 95%CI: 1.18-17.32; р<0.05) (frequency distribution of 73.7 %). Endothelial dysfunction is a pathogenetic link of excessive body weigh in pregnancy.

Abstract
The NOS3 gene polymorphisms T-786C, G894T and VNTR 4b/a are associated with a predisposition to the development of Metabolic Syndrome (MetS). The NOS3 gene contributes to a normal pregnancy and fetal development. According to their birthweight, newborns can be classified as: small (SGA), adequate (AGA) or large (LGA) for gestational age. The SGA and LGA present a higher risk of developing disorders related to MetS, both during childhood and adulthood. Therefore, the aim of this work is to relate the incidence of G894T, T-786C and VNTR 4b/a on SGA and LGA newborns and their mothers. 204 blood samples were collected from mothers (102) and the umbilical cords of 102 newborns (SGA = 12; AGA = 47; LGA = 43). The genotyping was performed through PCR-RFLP to evaluate presence of the G894T, T-786C and VNTR 4b/a polymorphisms. A significant difference was found between the groups of newborns in the genotypic frequency of T-786C, but without Hardy-Weinberg equilibrium. The VNTR 4b/a and the G894T polymorphisms showed no significance between the groups. The haplotype analysis showed that the SGA newborns presented the higher frequency of 4aGT (9.8%) and of the 4aTT combination (25.4%), while LGA newborns presented the higher frequency of the 4bTT haplotype (23%). Only the SGA newborns and their mothers presented the 4aTC haplotype. In conclusion, the NOS3 polymorphisms do not appear to be a factor to inadequate birth weight. However, the G894T and VNTR 4b/a polymorphisms, and the haplotype 4aTC, seem to influence the occurrence of SGA.

Abstract
Background: Soluble P-selectin (sP-selectin) is associated with risk factors for cardiovascular disease (CVD) but this association has not been evaluated in patients with schizophrenia. This study primarily evaluated the association of sP-selectin with plasma lipids and nitrite (NO2−) respectively in overweight/obese adults with schizophrenia. Methods: One-hundred and six patients with schizophrenia (mean age 32.9 years; 71.60% male) were recruited from a psychiatric hospital. Participants completed a structured interview and provided a fasting blood sample. Body mass index (BMI) was used to divide the sample into normal weight and overweight/obese groups. Pearson’s and partial correlation coefficients (controlling for age, sex, race, education, and inflammation) were calculated to examine the association of sP-selectin with plasma lipids, and NO2− in the overweight/obese patients (primary analysis), as well as in the normal weight patients and the total sample (exploratory analyses). Results: After controlling for potential confounders, sP-selectin positively correlated with triglycerides (r = 0.38, p = 0.01) and NO2− (r = 0.40, p < 0.01) in the overweight/obese group only. Conclusions: Future longitudinal studies should evaluate the utility of sP-selectin as a biomarker of CVD in overweight/obese adults with schizophrenia (for example, by relating sP-selectin to incidence of cardiovascular events).

Metabolic syndrome is negatively associated with cognition among endothelial nitric oxide synthase (eNOS)- 786C carriers in schizophrenia-spectrum disorders. J Psychiatr Res 2019; 117:142-147. [PMID: 31421598 PMCID: PMC6707862 DOI: 10.1016/j.jpsychires.2019.07.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/23/2019] [Revised: 06/30/2019] [Accepted: 07/25/2019] [Indexed: 02/08/2023]
Abstract
Although metabolic syndrome and cognitive inefficiencies are well-described common complications of schizophrenia, their association remains inconsistent, potentially due to poorly understood mechanisms underlying their relationship. Variability in the endothelial nitric oxide synthase (eNOS) gene, specifically the T-786C variant, has been separately associated with cognition and metabolic syndrome, with worse outcomes for eNOS-786C carriers likely occurring via negative effects on blood vessel functioning. However, the interaction between eNOS and metabolic syndrome in cognition among adults with schizophrenia is unknown. This study aimed to test the main and interaction effects of the eNOS-786C allele in cognition using hierarchical regression analyses controlling for age, sex, education, race, and antipsychotic exposure. Metabolic syndrome, eNOS T-786C genotype, and cognitive performance were assessed in 226 community-dwelling participants with chronic schizophrenia-spectrum disorders. Results demonstrated a significant interaction between metabolic syndrome and the eNOS-786C allele. Specifically, among eNOS-786C carriers only, metabolic syndrome was independently associated with lower scores in processing speed and verbal fluency, and predicted 12.5% and 15.8% of variance in performance, respectively. These results suggest that the additive negative effects of eNOS-786C and metabolic syndrome on blood vessel functioning may be severe enough to negatively impact cognition. The finding that metabolic syndrome is associated with worse cognition only in the presence of the eNOS-786C allele may clarify extant inconsistencies in the literature. These findings provide preliminary evidence that may inform interventions to reduce cognitive morbidity among adults with schizophrenia.

Gastrointestinal Dysfunctions Are Associated with IL-10 Variants in Parkinson's Disease. PARKINSONS DISEASE 2019; 2018:5908359.

Abstract
Inflammation has been demonstrated to be involved in Parkinson's disease (PD) pathogenesis. There were evidences that the disturbance of the protective function of IL-10 gene contributed to PD. In our study, haplotype analyses were conducted of IL-10 rs1800871 and rs1800872 on 371 PD patients. Because the two SNPs exposed significant linkage disequilibrium demonstrated by Haploview software, we included 177 carriers of both rs1800871 and rs1800872 and 190 noncarriers in clinical phenotype analyses. As to nonmotor symptoms, the score of the gastrointestinal dysfunction domain in Nonmotor Symptom Scale (NMSS) was lower in the carrier group of both SNPs than in the noncarrier group in PD patients (SC: -0.198, p : 023). Other nonmotor symptoms reflected by relevant rating scales showed negative results. As to comorbidity, no significant statistical significance was observed between the two SNPs and Charlson Comorbidity Index (CCI). In conclusion, we found less severe gastrointestinal dysfunctions of both IL-10 rs1800871 and rs1800872 carriers than noncarriers in PD.
