Abstract:BACKGROUND: Since this Nrf2-dependent cellular defense response is able to protect multi-organs, including cancer, neurodegenerative diseases, cardiovascular疾病,炎症和慢性肺损伤。尚未阐明肺毒性中的表瓜蛋白酶(EGCG)和NRF2/KEAP1信号机制的抗氧化剂和抗炎潜力。在目前的研究中,我们证明了EGCG对大鼠氧化应激介导的氧化应激介导的肺损伤的保护性疗效。
方法: 将动物分为四组。第1组:对照大鼠接受了正常的盐水;第2组大鼠仅接受EGCG(40mg/kg/bw)持续四个星期; Group 3 rats received Fl (25mg/kg/bw) alone for four weeks, Group 4 rats received EGCG (90min before administration) along with Fl for four weeks.
RESULTS: Oral administration of Fl (25mg/kg/bw) significantly (p<0.05) increased the ROS, inflammatory大鼠的细胞因子,肺水肿,甲醛(MDA)和髓过氧化物酶(MPO)。此外,在KEAP1蛋白增加的情况下,施用FL后(P <0.05)会降低抗氧化剂状态NRF2和HO-1。组织学和免疫组织化学(INOS)研究还显示,FL引起的肺组织显着(P <0.05)变化老鼠的e。 EGCG的预热(p <0.05)通过激活NRF2转运到核的激活,可以显着改善抗氧化剂状态,并抑制氧化应激,炎症细胞因子和KEAP1蛋白。 Moreover, the molecular docking studies also support the antioxidant potential of EGCG and Nrf2 activation.
CONCLUSION: Taken together, our data indicate that EGCG potentially abrogates Fl induced oxidative lung injury by activation of the Nrf2/Keap1 pathway in大鼠。
