In worldwide, one of the most important cancer-related death is lung cancer. Also has the highest mortality rate between various cancer types. The count of lung cancer occurrence is increasing with an increased frequency by smoking. Proficient chemoprevention approaches are needed to prevent the occurrence of lung cancer. Therefore, the aim of this exploration is to determine the therapeutic impact on the immune modulatory effect of rhaponticin on lung tumorigenesis and cytotoxicity effect in A549 cells of human lung cancer. Lung cancer tumorigenesis in mice was challenged with benzo(a)pyrene (BaP) with 50 mg/kg bodyweight (b.wt) as oral administration for 6 weeks (two times/week). Rhaponticin were given orally 30 mg/kg b.wt (two times/week) in BaP induced mice from 12 weeks to 18 weeks. After treatment completes, the body weight was measured and then blood, lung tissue was collected for various parameters detection. The results evidenced that BaP induced mice decreased the bodyweight, increased lung weight, increased tumor markers (AHH, CEA and LDH), and increased the proinflammatory cytokines. The enzyme catalase, superoxide dismutase activity was decreased and increased lipid peroxidation in immune comprising cells compared with the control cells. Moreover, rhaponticin treatment improves in chemical assays and also the histopathological alteration of lung tissues. The present findings provide evidence about the therapeutic potentials of rhaponticin against BaP triggered lung tumorigenesis.
在全球范围内,与癌症相关的最重要死亡原因之一是肺癌。它在各种癌症类型中也具有最高的死亡率。肺癌的发病率随着吸烟频率的增加而上升。需要有效的化学预防方法来预防肺癌的发生。因此,本研究的目的是确定rhaponticin对肺癌发生的免疫调节作用以及对人肺癌A549细胞的细胞毒性作用的治疗影响。用50mg/kg体重的苯并(a)芘(BaP)对小鼠进行口服给药,每周两次,持续6周,以诱导肺癌发生。从第12周开始至第18周,对BaP诱导的小鼠口服给予30mg/kg体重的rhaponticin(每周两次)。治疗结束后,测量体重,然后采集血液、肺组织用于各种参数检测。结果表明,BaP诱导的小鼠体重下降,肺重量增加,肿瘤标志物(AHH、CEA和LDH)升高,促炎细胞因子增加。与对照细胞相比,免疫细胞中的过氧化氢酶、超氧化物歧化酶活性降低,脂质过氧化增加。此外,rhaponticin治疗改善了化学检测结果以及肺组织的组织病理学改变。本研究结果为rhaponticin对BaP引发的肺癌发生的治疗潜力提供了证据。
