Open Med (Wars) 2022; 17:1455-1465. [PMID: 36128448 PMCID: PMC9449690 DOI: 10.1515/med-2022-0549] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Revised: 08/03/2022] [Accepted: 08/10/2022] [Indexed: 11/16/2022] Open
Abstract
Genetic variation in UDP-glucuronosyltransferase 1A1 gene (UGT1A1) is a lithogenic risk factor for gallstone formation. This study aimed to assess genotype and allele frequencies of common UGT1A1 variants in patients with gallstone and hepatitis B virus (HBV)-related hepatic failure. This study enrolled 113 healthy individuals (CTRL), 54 patients with HBV infection (HBV), 134 patients with gallstone-free hepatic failure and HBV infection, and 34 patients with gallstone-related hepatic failure and HBV infection (GRHF). Peripheral venous blood samples were collected for genomic DNA isolation. Polymerase chain reaction amplification was carried out for UGT1A1, followed by direct sequencing. Analysis for genotype and allele frequencies of UGT1A1 variants (UGT1A1*6, UGT1A1*27, UGT1A1*28, and UGT1A1*60) was performed. The allele distributions of the four groups did not deviate from Hardy–Weinberg equilibrium. Allele (A) and genotype (CA) frequency distributions of UGT1A1*27 were significantly different between GRHF and CTRL, or between GRHF and HBV. GRHF and CTRL exhibited significant differences in allele (A) and genotype (CA) frequency distributions of UGT1A1*28. Linkage disequilibrium analysis suggested that haplotype G-G-[TA]7-T may be associated with gallstone in HBV-related hepatic failure. Our data reveal that UGT1A1*27 and UGT1A1*28 variants are significantly observed in patients with GRHF compared to healthy individuals.

Abstract
Hyperbilirubinemia is the main mechanism that causes neonatal jaundice, and genetics is one of the risk factors of hyperbilirubinemia. Therefore, this study aims to explore the correlation between two genes, UGT1A1 and SLCO1B1, and hyperbilirubinemia in Thai neonates. One hundred thirty seven neonates were recruited from Division of Clinical Chemistry, Ramathibodi Hospital. UGT1A1*28 and *6 were determined by pyrosequencing whereas, SLCO1B1 388A > G and 521 T > C genetic variants were determined by TaqMan® real-time polymerase chain reaction. Neonates carrying with homozygous (AA) and heterozygous (GA) variants in UGT1A1*6 were significantly related to hyperbilirubinemia development compared with wild type (GG; P < 0.001). To the combined of UGT1A1, total bilirubin levels in homozygous variant were higher significantly than heterozygous variant and wild type (P = 0.002, P = 0.003, respectively). Moreover, SLCO1B1 combination was significant differences between the hyperbilirubinemia and the control group (P = 0.041). SLCO1B1 521 T > C variant provide protection for Thai neonatal hyperbilirubinemia (P = 0.041). There are no significant differences in UGT1A1*28 and SLCO1B1 388A > G for the different severity of hyperbilirubinemia. The combined UGT1A1*28 and *6 polymorphism is a strong risk factor for the development of severe hyperbilirubinemia in Thai neonates. Therefore, we suggest neonates with this gene should be closely observed to avoid higher severities of bilirubin.

Abstract
High-throughput screening facilitates the rapid identification of novel hit compounds; however, it remains challenging to design effective high-throughput assays, partially due to the difficulty of achieving sensitivity in the assay techniques. Among the various analytical methods that are used, fluorescence-based assays dominate owing to their high sensitivity and ease of operation. Recent advances in activity-based sensing/imaging have further expanded the availability of fluorescent probes as monitors for high-throughput screening of result outputs. In this study, we have reviewed various activity-based fluorescent probes used in high-throughput screening assays, emphasizing their structure-related working mechanisms. Moreover, we have explored the possibility of the development of additional and better probes to boost hit identification and drug development against various targets.

Abstract
BACKGROUND/OBJECTIVES Gilbert's syndrome (GS) is a hereditary pathology that affects approximately 10% of the world's population. In most cases, GS is associated with the UGT1A1∗28 polymorphism of UGT1A1 gene coding the enzyme bilirubin uridine diphosphate glucuronosyltransferase (UGT-1A) which plays a key role in the bilirubin metabolism. The presence of an additional TA repeat in the TATA box of the UGT1A1 gene promoter (the allelic variant of 7TA, abbreviated as UGT1A1∗28) leads to a significant decrease in the enzymatic activity of UGT-1A in the liver and to decrease in glucuronidation process as a consequence. The aim of the study is to estimate the prevalence of the 6TA/6TA, 6TA/7TA, and 7TA/7TA genotypes of UGT1A1 promoter and to analyze the effect of these variants on bilirubin levels in healthy men in North-West Russia and patients with a clinical diagnosis of GS. METHODS Genotyping of the UGT1A1 ∗28 (rs8175347) polymorphism was carried out by real-time PCR. RESULTS The results obtained indicate an increased probability of GS developing in residents of the North-West region of Russia compared with other representatives of the Caucasians. CONCLUSIONS Despite the fact that the level of serum bilirubin increases with the rise in the number of additional TA dinucleotides in the UGT1A1 gene promoter tests of clinical manifestations only (jaundice, fatigue, sleep disturbances, nausea, belching, and so on) and increased bilirubin levels in patients with normal liver function do not allow unequivocally diagnose GS. UGT1A1∗28 genotyping should be used as a prognostic risk factor for such pathology development.

Abstract
The efficacy, safety, and tolerability of drugs are dependent on numerous factors that influence their disposition. A dose that is efficacious and safe for one individual may result in sub-therapeutic or toxic blood concentrations in others. A significant source of this variability in drug response is drug metabolism, where differences in presystemic and systemic biotransformation efficiency result in variable degrees of systemic exposure (e.g., AUC, Cmax, and/or Cmin) following administration of a fixed dose.Interindividual differences in drug biotransformation have been studied extensively. It is recognized that both intrinsic factors (e.g., genetics, age, sex, and disease states) and extrinsic factors (e.g., diet , chemical exposures from the environment, and the microbiome) play a significant role. For drug-metabolizing enzymes, genetic variation can result in the complete absence or enhanced expression of a functional enzyme. In addition, upregulation and downregulation of gene expression, in response to an altered cellular environment, can achieve the same range of metabolic function (phenotype), but often in a less predictable and time-dependent manner. Understanding the mechanistic basis for variability in drug disposition and response is essential if we are to move beyond the era of empirical, trial-and-error dose selection and into an age of personalized medicine that will improve outcomes in maintaining health and treating disease.

Abstract
BACKGROUND Chronic Hepatitis C virus (HCV) infection is associated with progressive liver inflammation which in turn leads to cirrhosis and finally causes hepatocellular carcinoma (HCC). By different escape mechanisms, the virus succeeds to evade the innate and acquired immune responses to establish chronic infection. AIM This study aimed to evaluate the level of chemokine CXCL9 and its correlation with some biochemical parameters in different subjects of HCV patients. MATERIALS AND METHODS A total of 83 persons participated in this study including healthy subjects without both HCV antibodies and HCV RNA (22.9%), HCV treated responders accomplished SVR post treatment, with HCV antibodies and absence of HCV RNA (24.1%), spontaneous or natural clearance patients, with positive HCV antibodies and negative HCV RNA without treatment (26.5%) and chronic HCV-patients, with both positive HCV antibodies and HCV RNA with no treatment (26.5%). HCV RNA was quantitated by real time PCR and serum CXCL9 level was measured by ELISA commercial kit pre-coated with human MIG/CXCL9 antibody. Assessment of biochemical and hematological parameters was carried out. RESULTS Data showed that, the level of CXCL9 was significantly increased in chronic individuals (627.1 pg/ml) (P< 0.001) than spontaneous clearance (107.76 pg/ml) and responder subjects (117.28 pg/ml) (P⩽ 0.05). No correlation has been found between CXCL9 level and viral load. Furthermore, CXCL9 levels correlated variably with some biochemical and hematological parameters according to each subject. CONCLUSION Serum Chemokine CXCL9 level is associated with spontaneous clearance of HCV and response to HCV treatment, which may be identified as a predictive marker among HCV patients.

Abstract
Background: This study aimed to evaluate the relationship between UGT1A1*28 gene polymorphism and the risk of neonatal hyperbilirubinemia (NHBI).Methods: The studies meet certain selection condition which was obtained from databases such as PubMed, Embase, and Cochrane Library. Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included studies. Meta-analysis was performed according to criteria such as country. Hardy-Weinberg's equilibrium (HWE) tests were performed on the control group using chi-square test, while the evaluation index was represented by odds ratio (OR) and 95% confidence interval (CI). Egger's test and sensitivity analysis were used to evaluate the publication bias and reliability, repetitively.Results: Totally, four studies with high overall quality were enrolled in this study. No association was observed between UGT1A1*28 gene polymorphisms and NHBI in allele model (TA7 versus TA6, OR (95% CI) = 2.13 (0.81-5.62), p = .13), codominance models (TA7/6 versus TA6/6, OR (95% CI) = 2.94 (0.90-9.57), p = .07; TA7/7 versus TA6/6, OR (95% CI) = 2.08 (0.37-11.52), p = .40), recessive model (TA7/7 versus TA6/6 + TA7/6, OR (95% CI) = 1.44 (0.41-5.14), p = .57), and dominant model (TA7/7 + TA7/6 versus TA6/6, OR (95% CI) = 2.92 (0.84-10.12), p = .09). Furthermore, there was no publication bias found in current meta-analysis.Conclusions: Gene polymorphism of UGT1A1*28 might not be associated with the risk of NHBI.

Abstract
Background Chronic hepatitis C (CHC) is a significant cause of liver related morbidity and mortality worldwide. The role of genetics in the host response to hepatitis C virus is not elucidated. Genetic variations in UGT1A1 gene are the most common cause of hereditary unconjugated hyperbilirubinemia-Gilbert syndrome. This is the first study investigating the association of UGT1A1 TA repeats promoter genotypes with the degree of liver injury, viremia and biochemical markers in CHC patients with advanced liver injury and late virological relapse. Methods Genetic testing of UGT1A1 TA repeats promoter genotypes was performed in 42 CHC patients with advanced fibrosis and cirrhosis who achieved sustained virological response and 42 healthy blood donors. CHC patients were evaluated for clinical findings, laboratory tests and imaging. Results UGT1A1*28 genotype (7/7 TA repeats) was observed in 23.8% CHC patients and 16.7% healthy controls with no significant difference in genotype frequencies (p=0.49). Pretreatment levels of ferritin and bilirubin were associated with the presence of UGT1A1*28 genotype, indicating its potential as a predictive marker. However, in our study, there was no correlation of UGT1A1*28 genotype with the degree of fibrosis or viremia. During antiviral treatment, dose reductions and treatment interruptions, as well as treatment success and occurrence of late virological relapse were not related to the presence of UGT1A1*28 genotype in CHC patients with severe liver injury. Conclusions Frequencies of UGT1A1*28 genotype are high in both Serbian CHC patients and healthy subjects. The presence of UGT1A1*28 genotype was not associated with ribavirin-related adverse effects and had no effect on long term outcome in CHC patients.

Abstract
The UGT1A1 enzyme is involved in the metabolism of bilirubin and numerous medications. Unconjugated hyperbilirubinemia, commonly presented as Gilbert syndrome (GS), is a result of decreased activity of the UGT1A1 enzyme, variable number of TA repeats in the promoter of the UGT1A1 gene affects enzyme activity. Seven and eight TA repeats cause a decrease of UGT1A1 activity and risk GS alleles, while six TA repeats contribute to normal UGT1A1 activity and non-risk GS allele. Also, the UGT1A1 (TA)n promoter genotype is recognized as a clinically relevant pharmacogenetic marker. The aim of this study was to assess diagnostic value of UGT1A1 (TA)n promoter genotyping in pediatric GS patients. Correlation of the UGT1A1 (TA)n genotypes and level of unconjugated bilirubin at diagnosis and after hypocaloric and phenobarbitone tests in these patients was analyzed. Another aim of the study was to assess pharmacogenetic potential of UGT1A1 (TA)n variants in Serbia. Fifty-one pediatric GS patients and 100 healthy individuals were genotyped using different methodologies, polymerase chain reaction (PCR) followed by acrylamide electrophoresis, fragment length analysis and/or DNA sequencing. Concordance of the UGT1A1 (TA)n promoter risk GS genotypes with GS was found in 80.0% of patients. Therefore, UGT1A1 (TA)n promoter genotyping is not a reliable genetic test for GS, but it is useful for differential diagnosis of diseases associated with hyperbilirubinemia. Level of bilirubin in pediatric GS patients at diagnosis was UGT1A1 (TA)n promoter genotype-dependent. We found that the frequency of pharmacogenetic relevant UGT1A1 (TA)n promoter genotypes was 63.0%, pointing out that UGT1A1 (TA)n promoter genotyping could be recommended for preemptive pharmacogenetic testing in Serbia.
