Int J Immunogenet 2022; 49:169-180. [PMID: 35485366 DOI: 10.1111/iji.12574] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 03/08/2022] [Accepted: 04/03/2022] [Indexed: 11/28/2022]
Abstract
Host immune system genes play key roles in the progression of chronic hepatitis C virus (HCV) infection. Transporters associated with antigen processing (TAP) play an important role in the loading of viral peptides onto MHC class I molecules. This study aimed to investigate the association between TAP gene polymorphisms and chronic HCV in a Chinese Han population. A total of 232 chronic hepatitis C (CHC) patients and 362 healthy individuals were recruited from the Han population in Yunnan province in southwest China, and a TaqMan SNP genotyping assay was used to detect six single nucleotide polymorphisms (SNPs) of TAP1 and three SNPs of TAP2 genes. The association of the TAP gene with CHC was analysed at the allele, genotype, and haplotype levels. There were no significant differences in the allele and genotype frequencies of these SNPs in the TAP gene between CHC patients and controls after Bonferroni correction. A novel TAP1 allele (TAP1*unknown_1: rs41555220-rs41549617-rs1057141-rs1135216-rs1057149-rs41551515: G-G-A-G-G-G) was only present in the CHC group, and this allele significantly increased susceptibility to CHC (p = .005, odds ratio [OR] = 11.105. 95% confidence interval [CI]: 1.362-90.558). Homozygous TAP1*03:01/TAP1*03:01 was observed only in the CHC group that exhibited an obvious risk for CHC (p = .002, OR = 9.637, 95% CI: 1.153-80.574). And the haplotype TAP1*unknown_1-TAP2*01:01 was only present in the CHC group and indicated a significant risk for CHC (p = .002, OR = 9.498, 95% CI: 1.140-79.149). We observed significant interactions among HLA-A, -B,C, TAP1, and TAP2 alleles, and combination analysis revealed that the combination of TAP1*01:01-TAP2*01:01-HLA-B*35:01 was only present in the control group (2.2%) and resulted in significantly increased resistance to CHC (p = .002, OR = 0.096, 95% CI: 0.012-0.759). Whereas, the combination of TAP1*01:01-TAP2*01:01-HLA-C*07:02 and TAP1*03:01-TAP2*01:01-HLA-C*01:02 increased the susceptibility to CHC significantly (p = .001, OR = 2.016, 95% CI: 1.309-3.106 and p = .002, OR = 8.070, 95% CI: 1.018-63.997, respectively). Our results indicated that TAP and HLA-I may exert a combined effect on CHC susceptibility in the Chinese Han population.

Abstract
Introduction: Globally, Breast cancer (BC) is considered the second most common type of cancer and the principal cause of death among affected women. Aim: In this study, we targeted to demonstrate the association of MTHFR single gene polymorphisms (SNPs) with the susceptibility of breast cancer, in addition to its correlation with the clinical patient features. Patients and Methods: This work was conducted on 100 Egyptian females with breast cancer and 60 healthy matched controls. Clinical examinations and pathological investigations were recorded. Genotyping of MTHFR polymorphisms C677T (rs1801133) and A1298C (rs1801131) by using Restriction Fragment length Polymorphisms (RFLP) and Sequencing assays were performed. Univariate, Multivariate and Haplotype analysis for the allelic frequencies and the association with clinicopathological features of BC were assessed. Results: The present data showed a strong significant association between the CT and TT of MTHFR (C677T), and AC and CC of (A1289C) with the susceptibility of BC showing highly statistical P- value (0.001). It was also demonstrated that the most frequent haplotype of the two loci of MTHFR (rs1801133-rs1801131) was TC. The latter was strongly associated with the aggressive clinical features of each of tumor size, advanced stage, involvement of cancer in lymph nodes, overexpression of HER2neu and dual negativity of both ER and PR hormones. Conclusions: SNPs within the MTHFR gene (C677T) and (A1289C) have strong correlation with BC among Egyptian females; These SNPs should be considered as important prognostic markers for identifying the individuals at high risk of developing BC and its progression.

Abstract
BACKGROUND Hepatocellular carcinoma is a major health problem worldwide especially in Egypt. It accounts for the fifth common cancer and the second cause of death among different cancers. This study investigated the efficacy and molecular mechanism of Nisin and/or Thioridazine as anticancer treatment on human liver cancer HepG2 cell line. METHODS Nisin and Thioridazine were applied for 24 h on human liver cancer cell line (HepG2). 3-(4, 5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was done to assess the cytotoxicity of Nisin and Thioridazine. Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR) was used for the assessment of PI3K, AKT, SIRT-1, and NRF2 expression in the treated cell line. The protein level of reactive oxygen species (ROS) and vascular endothelial growth factor (VEGF) was measured in the collected media by ELISA technique. Western blot analysis was done for, tAKT, pAKT, tPI3K, and pPI3K. RESULTS Cell proliferation results showed that compared with the untreated cancer, Nisin and/or Thioridazine treated groups had decreased cell proliferation (p value< 0.0001). Nisin and/or Thioridazine decreased PI3K/AKT mRNA and protein expression in hepatocellular carcinoma cells (HCC). Also Nisin and/or Thioridazine decreased anti-oxidative SIRT1/NRF2 mRNA expression. ROS level highly increased with Nisin and/or Thioridazine treatment in contrast to VEGF protein level which was highly decreased. CONCLUSION These results introduce Nisin and Thioridazine as new therapeutic lines in HCC.

Abstract
Hepatitis C virus (HCV) is the leading cause of liver fibrosis and hepatocellular carcinoma (HCC). At present, there is no predictive biomarker for the patients at high risk of developing HCC. In this study, we examined the association between single-nucleotide polymorphisms (SNPs) in 3 innate immunity genes [2'-5'oligoadenylate synthetase 1 (OAS1) rs10774671, interleukin 28B (IL28B) rs12979860, and low molecular mass polypeptide 7 (LMP-7) at codon 49] besides cytomegalovirus (CMV) coinfection and susceptibility to HCC in genotype 4 (GT4) chronically infected Egyptian patients. SNPs were determined using restriction fragment length polymorphism analysis in DNA from HCC patients (n = 34) and compared with either controls (n = 70) or patients with early grades of liver fibrosis (n = 49). Our results demonstrated that patients bearing the genetic combination consisting of LMP-7 CA/AA [OR 4.75, 95% confidence interval (CI) 1.443-15.631, P = 0.007] and IL28B rs12979860 CT/TT (OR 6.00, 95% CI 1.603-22.455, P = 0.004) and positive for CMV viremia (OR 3.11, 95% CI 1.151-8.412, P = 0.02) were more likely to have HCC. However, OAS1 rs10774671 does not seem to contribute to the development of HCC. Binary regression analysis indicated that HCC risk significantly increases with the presence of each unfavorable genotype (LMP-7 CA/AA, IL28B rs12979860 CT/TT), when accompanied by the existence of CMV coinfection (probability of HCC risk is 0.8 for combined factors versus 0.14, 0.07, and 0.07 for individual factor IL28B, LMP-7, and CMV; respectively). These data suggest that the 2 SNPs and the coinfection in concert have potential in predicting the risk of HCC development in patients infected with HCV GT4.

A Study of CC-Chemokine Receptor 5 (CCR5) Polymorphism on the Outcome of HCV Therapy in Egyptian Patients. HEPATITIS MONTHLY 2013; 13:e13721. [PMID: 24403912 PMCID: PMC3877652 DOI: 10.5812/hepatmon.13721] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/20/2013] [Revised: 09/07/2013] [Accepted: 10/02/2013] [Indexed: 02/07/2023]
Abstract
BACKGROUND Chronic hepatitis C virus (HCV) infection is a globally serious public health issue. OBJECTIVES In this study, we investigated CC chemokine receptor 5 (CCR5-59029) polymorphism which is considered an important component of the immune system in determining the outcome of HCV infection. Its critical role as a marker in response to interferon therapy of HCV infection is also investigated besides its effect on other clinical patient factors. PATIENTS AND METHODS This study was conducted on 82 Egyptian patients with chronic Hepatitis C Virus (HCV) infection who received PEG-INF + Ribavirin treatment for 48 weeks. The study was also conducted on 50 healthy controls (with negative results for HCV antibody and RNA PCR). Full history of patients in this study was recorded. Clinical and histological examinations, qualitative HCV nested RT-PCR, quantitative real -time PCR, and genotyping of HCV RNA genome were performed. CCR5-59029 polymorphism with nucleotide substitution from G to A was amplified. The amplicons were digested with restriction endonuclease Bsp 1286I, and produced RFLPs of the CCR5 genotypes were determined. RESULTS The present study showed a significant association between the functional SNP of CCR5 gene and the viral response to interferon in chronic HCV Egyptian patients. It was shown that the higher fibrosis stages (F2-F4) had significant association with nonresponse to treatment compared to the lower fibrosis stages (F0-F1) (95% confidence: 5.497 - 55.074, P = 0.0001). In addition, worse liver activity grade (A2-A3) had a very highly significant association with non-responder HCV patients compared to those with better liver activity grade (A1) (95% confidence: 2.242 - 20.974, P = 0.0007). Most importantly HCV patients with G allele had a high significant association with nonresponse to treatment, higher fibrosis stages and worse liver activity grades, while the A allele had a high significant association with sustained response, low fibrosis stages and relatively better liver activity grade (95% confidence: 3.347 - 15.036, P = 0.0001). CONCLUSIONS SNPs within the CCR5 gene should be considered as an important factor used in combination with other host gene SNPs when developing a mathematical model for anticipating response to HCV therapy.
