ABSTRACT

The hepatitis B virus (HBV) infection-induced chronic inflammation is considered to be the major etiological factor for HBV-related disease chronicity. Cytokines act as the key coordinators of the inflammatory responses involved in HBV disease pathogenesis. The present study assessed association among IL-12B(+1188), IL-2(−330), TGF-β1(−509), and IL-4(−590) genotypes; mRNA; and protein levels with HBV-hepatocellular carcinoma (HCC) risk in India. For this, 403 subjects (153 controls, 67 inactive HBV-carriers, 62 chronic-active HBV patients, 62 HBV-cirrhotics, and 59 HBV-HCC ssubjects) were enrolled in the study. The genotyping was carried by polymerase chain reaction (PCR)-restriction fragment length polymorphism (IL-12+1188A/C, IL-2−330T/G, and TGF-β1−509C/T), and allele specific (AS)-polymerase chain reaction (IL-4−590C/T). Enzyme-linked immunosorbent assay and reverse transcriptase–polymerase chain reaction methods were used for assessing protein and the mRNA expression, respectively, of the mentioned cytokines. The study revealed that the IL-12B(+1188) CC genotype shared a significant positive association with hepatitis, among controls. While, in the case of IL-2(−330), both the TG and GG genotypes were not significantly associated with HCC risk. The TGF-β1(−509) TT genotype acted as a potential protective factor for cirrhosis and the HCC risk, among carriers. On the contrary, the IL-4(−590) CT genotype was found to be a vital protective factor for the development of hepatitis, among carriers. Besides, IL-12B, TGF-β1, and IL-2 seem to be majorly involved in the development of HCC, while, IL-4 might be responsible for the progression of the HBV disease till cirrhosis development. These initial findings are indicative of the vital role of genotypes and/or levels of IL-12B, IL-2, IL-4, and TGF-β1 in HBV disease chronicity in Indian population.

摘要

乙型肝炎病毒(HBV)感染引起的慢性炎症被认为是对HBV相关疾病慢性化的主要致病因素。细胞因子作为参与乙肝发病机制的炎症反应的主要协调人。本研究中的IL- 12B中评估协会( 1188 ),IL- 2 ( -330 ) ,转化生长因子- β1 ( -509 )和IL -4( -590 )基因型;的mRNA和蛋白质水平的HBV -肝细胞癌( HCC)的风险在印度。对于这一点, 403例( 153控制, 67非活动性HBV携带者, 62慢性活动性HBV患者, 62乙肝肝硬化患者,和59 HBV-HCC ssubjects )参加了这项研究。基因分型进行聚合酶链反应(PCR ) - 限制性片段长度多态性( IL-12的1188的A / C, IL-2 330T / G和TGF-β1 - 509C / T)和等位基因特异性( AS ) - 聚合酶链反应( IL-4 - 590C / T) 。酶联免疫吸附法和逆转录酶 - 聚合酶链反应方法进行了用于评估所提到的细胞因子的蛋白质和mRNA的表达,分别。该研究发现, IL- 12B ( 1188 ) CC基因型与共享甲肝显著正相关,其中控制。同时,在IL-2( -330 )的情况下,双方的TG和GG基因型不显著患有HCC的风险。转化生长因子-β1 ( -509 ) TT基因型担任为肝硬化和肝癌风险的一个潜在的保护性因素,运营商之间。与此相反,在IL-4( -590 ) CT基因型被发现是一个重要的保护因子对肝炎的发展,运营商之间。此外,IL- 12B ,TGF-β1和IL- 2似乎是majorly参与HCC的发展,而IL-4可能负责乙肝病直到肝硬化发展的进程。这些初步的研究结果均显示出基因型和/或IL - 12B , IL- 2 , IL- 4水平的重要作用,和TGF-β1在印度人口乙肝病毒慢性疾病。
