The present study evaluated the role of dietary folate modulations in the development of hepatocellular carcinoma (HCC) in a rat model. Male Wistar rats were given diethylnitrosamine (DEN) carcinogen for a period of 18 weeks in addition to different folate modulations. Biochemical parameters were assayed and liver tissues were examined using various histopathological stains viz. Hematoxylin and eosin (H&E), Masson’s trichrome, Immunohistochemistry (IHC) staining for arginase-1 and α-smooth muscle actin (SMA). Serum folate and hepatic folate stores were decreased and increased in folate deficiency (FD) and folate oversupplemented (FO) group respectively. Analysis of serum liver function tests revealed deranged liver functioning in all the groups. H&E staining of rat liver demonstrated vague nodularity from 2nd to 8th week, fibrosis from 10th to 15th week, cirrhosis and HCC from 16th to 18th week. Combining the observations of H&E with IHC for arginase-1, 14 (50%), 11 (39.3%) and 17 (58.6%) rats showed HCC positivity in FN (folate normal), FD and FO diets respectively. IHC for α-SMA depicted increased staining with progression of the disease from fibrosis to cirrhosis in all the dietary groups. Collectively, findings of all the histopathological stains, revealed increase in the number of cirrhotic cases and decrease in the number of HCC cases in FD group, indicating delayed progression of HCC with FD. Moreover, FO led to more number of HCC and reduction in the number of cirrhotic cases, signifying early progression of HCC.

叶酸的膳食调节影响大鼠模型中二乙基亚硝胺诱导的肝细胞癌的发展

本研究评估了膳食叶酸调节在大鼠模型肝细胞癌(HCC)发展中的作用。除了不同的叶酸调节外,雄性 Wistar 大鼠还被给予二乙基亚硝胺 (DEN) 致癌剂 18 周。测定生化参数并使用各种组织病理学染色即检查肝组织。苏木精和伊红 (H&E)、马森三色、精氨酸酶 1 和 α-平滑肌肌动蛋白 (SMA) 的免疫组织化学 (IHC) 染色。叶酸缺乏(FD)组和叶酸过量(FO)组的血清叶酸和肝脏叶酸储存分别减少和增加。血清肝功能测试分析显示,所有组的肝功能均出现紊乱。大鼠肝脏H&E染色显示第2周至第8周有模糊的结节,第10至15周为纤维化,第16至18周为肝硬化和肝癌。结合 H&E 和 IHC 对精氨酸酶-1、14 (50%)、11 (39.3%) 和 17 (58.6%) 大鼠的观察结果,分别在 FN(正常叶酸)、FD 和 FO 饮食中显示出 HCC 阳性。α-SMA 的 IHC 表明,在所有饮食组中,随着疾病从纤维化发展到肝硬化,染色增加。总的来说,所有组织病理学染色的结果显示,FD 组中肝硬化病例数增加,HCC 病例数减少,表明 FD 导致 HCC 进展延迟。此外,FO导致HCC数量增加和肝硬化病例数量减少,这意味着HCC的早期进展。3%)和 17 只(58.6%)大鼠在 FN(正常叶酸)、FD 和 FO 饮食中分别表现出 HCC 阳性。α-SMA 的 IHC 表明,在所有饮食组中,随着疾病从纤维化发展到肝硬化,染色增加。总的来说,所有组织病理学染色的结果显示,FD 组中肝硬化病例数增加,HCC 病例数减少,表明 FD 导致 HCC 进展延迟。此外,FO导致HCC数量增加和肝硬化病例数量减少,这意味着HCC的早期进展。3%)和 17 只(58.6%)大鼠在 FN(正常叶酸)、FD 和 FO 饮食中分别表现出 HCC 阳性。α-SMA 的 IHC 表明,在所有饮食组中,随着疾病从纤维化发展到肝硬化,染色增加。总的来说,所有组织病理学染色的结果显示,FD 组中肝硬化病例数增加,HCC 病例数减少,表明 FD 导致 HCC 进展延迟。此外,FO导致HCC数量增加和肝硬化病例数量减少,这意味着HCC的早期进展。结果显示,FD 组肝硬化病例数增加,HCC 病例数减少,表明 FD 导致 HCC 进展延迟。此外,FO导致HCC数量增加和肝硬化病例数量减少,这意味着HCC的早期进展。结果显示,FD 组肝硬化病例数增加,HCC 病例数减少,表明 FD 导致 HCC 进展延迟。此外,FO导致HCC数量增加和肝硬化病例数量减少,这意味着HCC的早期进展。
