Cheong-Pye-Ko (CPK) and Kyung-Ok-Ko (KOK) are traditional herbal medicine prescriptions that have been used in oriental medicine as tonics for pulmonary-related diseases for centuries. However, the effects of a mixture of CPK and KOK (C-KOK) on cytokine-mediated pulmonary damage have not yet been elucidated. This study used lipopolysaccharide (LPS)-activated human pulmonary artery endothelial cells (HPAECs) to examine the effects of C-KOK on the induction of heme oxygenase-1 (HO-1) and the expression of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2). Moreover, a mouse model was used to determine if C-KOK affected the expression of tumor necrosis factor (TNF)-α and iNOS in the lung tissues of LPS-treated mice. The results showed that C-KOK induced the translocation of Nrf2 from the cytosol to the nucleus by increasing Nrf2-antioxidant response elements (ARE) activity, increased the expression of HO-1, and decreased IL-1β and iNOS/NO production in the LPS-activated HPAECs. Specifically, the suppression of iNOS/NO expression from the administration of C-KOK was reversed by the RNAi knockdown of HO-1. In conclusion, these findings indicated that C-KOK produced a critical anti-inflammatory effect due to its HO-1 dependent downregulation of p-STAT-1 and NF-κB and the resultant inhibition of iNOS and also suggested that TNF-α was a potential target for HO-1. Therefore, the administration of C-KOK showed efficacy and might be a novel approach for the treatment of inflammatory pulmonary disease.

新型草药C-KOK通过抑制p-STAT-1和NF-κB抑制炎症基因iNOS

Cheong-Pye-Ko(CPK)和Kyung-Ok-Ko(KOK)是传统草药处方,已经在东方医学中用作肺相关疾病的补品已有数百年历史了。但是,尚未阐明CPK和KOK混合物(C-KOK)对细胞因子介导的肺损伤的影响。这项研究使用脂多糖(LPS)激活的人肺动脉内皮细胞(HPAEC)来研究C-KOK对血红素加氧酶-1(HO-1)的诱导以及诱导型一氧化氮合酶(iNOS)和环氧合酶2(COX-2)。此外,使用小鼠模型来确定C-KOK是否影响LPS治疗的小鼠肺组织中肿瘤坏死因子(TNF)-α和iNOS的表达。结果表明C-KOK通过增加Nrf2-抗氧化反应元件(ARE)的活性,增加HO-1的表达,降低IL-1β和iNOS / NO的产生来诱导Nrf2从胞质向核的转运。 LPS激活的HPAEC。具体而言,通过HO-1的RNAi敲低逆转了来自施用C-KOK的iNOS / NO表达的抑制。总之,这些发现表明,C-KOK由于其HO-1依赖性下调p-STAT-1和NF-κB以及对iNOS的抑制作用而产生了关键的抗炎作用,还表明TNF-α是一种抗炎药。 HO-1的潜在目标。因此,C-KOK的施用显示出功效,并且可能是治疗炎性肺疾病的新方法。在LPS激活的HPAEC中,HO-1的表达增加,而IL-1β和iNOS / NO的产生减少。具体而言,通过HO-1的RNAi敲低逆转了来自施用C-KOK的iNOS / NO表达的抑制。总之,这些发现表明,C-KOK由于其HO-1依赖性下调p-STAT-1和NF-κB以及对iNOS的抑制作用而产生了关键的抗炎作用,还表明TNF-α是一种抗炎药。 HO-1的潜在目标。因此,C-KOK的施用显示出功效,并且可能是治疗炎性肺疾病的新方法。在LPS激活的HPAEC中,HO-1的表达增加,而IL-1β和iNOS / NO的产生减少。具体而言,通过HO-1的RNAi敲低逆转了来自施用C-KOK的iNOS / NO表达的抑制。总之,这些发现表明,C-KOK由于其HO-1依赖性下调p-STAT-1和NF-κB以及对iNOS的抑制作用而产生了关键的抗炎作用,还表明TNF-α是一种抗炎药。 HO-1的潜在目标。因此,C-KOK的施用显示出功效,并且可能是治疗炎性肺疾病的新方法。这些发现表明,C-KOK由于其HO-1依赖性下调p-STAT-1和NF-κB以及对iNOS的抑制作用而产生了关键的抗炎作用,也表明TNF-α是潜在的抗炎靶标。 HO-1。因此,C-KOK的施用显示出功效,并且可能是治疗炎性肺疾病的新方法。这些发现表明,C-KOK由于其HO-1依赖性下调p-STAT-1和NF-κB以及对iNOS的抑制作用而产生了关键的抗炎作用,也表明TNF-α是潜在的抗炎靶标。 HO-1。因此,C-KOK的施用显示出功效,并且可能是治疗炎性肺疾病的新方法。
