OBJECTIVE This study aimed to investigate the role and potential mechanisms of Icotinib (ICO) on pulmonary fibrosis. METHODS C57BL/6 mice were randomly divided into Sham group, PF group, ICO 30 mg·kg-1 group and ICO 60 mg·kg-1 group, 8 rats in each group. A mouse model of PF was induced by intratracheal injection of bleomycin (3 mg·kg-1). Hematoxylin-eosin staining and Masson trichrome staining for lung tissues were performed to observe the pathological alterations and collagen deposition. Immunohistochemical detection of lung tissue collagen type Ⅰ (collagen Ⅰ) expression. In vitro, the lung epithelial cells were divided into control group, epidermal growth factor (EGF) group, EGF combined with ICO (0.1, 1, 10 mmol·L-1) groups. The protein expression of E-cadherin, α-SMA and nuclear transfer of NF-κB p65 were detected by immunofluorescence. The protein levels of Collagen Ⅰ, E-cadherin, α-SMA, Vimentin, phosphorylation epidermal growth factor receptor (p-EGFR), p-IκBα, p-NF-κB p65 and nuclear NF-κB p65 were detected by Western blot analysis in lung tissue and (or) cells. RESULTS The results demonstrated that ICO inhibited bleomycin-induced collagen deposition, reduced type Ⅰ collagen expression, alleviated bleomycin-induced EMT (increased E-cadherin expression and decreased Vimentin and α-SMA expression), and decreased phosphorylation of EGFR, IκBα, NF-κB p65 and nuclear translocation of NF-κB p65 in vivo. Furthermore, incubation of lung epithelial cells with EGF activated EMT and EGFR/NF-κB signaling pathway, and these effects were reversed by ICO In vitro. CONCLUSION In conclusion, ICO attenuates EGF-induced EMT in lung epithelial cells and bleomycin-induced pulmonary fibrosis in mice by downregulating EGFR/NF-κB pathway.

目的 探究埃克替尼(icotinib, ICO)的抗肺纤维化(pulmonary fibrosis, PF)作用及其潜在的分子机制。方法 C57BL/6小鼠随机分为假手术(Sham)组、PF组、ICO 30 mg·kg-1剂量组及ICO 60 mg·kg-1剂量组,每组n=8。单次气管注射博来霉素(BLM,3 mg·kg-1)建立小鼠PF模型。HE及Masson染色观察肺组织病理变化及胶原沉积情况。免疫组化检测肺组织Ⅰ型胶原(collagen Ⅰ)的表达。体外培养肺泡上皮细胞,实验设对照(control)组、表皮生长因子(epidermal growth factor,EGF)组(100 ng·mL-1)及EGF联合ICO(0.1、1、10 mmol·L-1)3个剂量组。免疫荧光法检测细胞E-钙黏蛋白(E-cadherin)和α-平滑肌肌动蛋白(α-SMA)的表达及核因子-κB(NF-κB)p65核转移情况。Western blots检测肺组织和(或)细胞collagen Ⅰ、E-cadherin、α-SMA、Vimentin、磷酸化表皮生长因子受体(phosphorylation epidermal growth factor receptor, p-EGFR)、磷酸化核因子κB抑制物α(p-IκBα)、磷酸化NF-κB p65(p-NF-κB p65)的蛋白水平及NF-κB p65核转移情况。结果 动物实验表明,ICO抑制了BLM诱导的胶原沉积,减少了Ⅰ型胶原的表达,减轻了博来霉素诱导的上皮-间充质转化(epithelial-mesenchymal transition,EMT) (E-cadherin表达增加,Vimentin和α-SMA表达减少),降低了EGFR,IκBα和NF-κB p65 的磷酸化水平并抑制了 NF-κB p65的核转移。细胞实验发现,EGF可激活肺泡上皮细胞EMT和EGFR/NF-κB信号通路,而ICO可逆转这一作用。结论 ICO可能通过抑制EGFR/NF-κB信号通路的活化,逆转了EGF诱导的EMT和博来霉素诱导的小鼠肺纤维化。

目的 探究埃克替尼(icotinib, ICO)的抗肺纤维化(pulmonary fibrosis, PF)作用及其潜在的分子机制。方法 C57BL/6小鼠随机分为假手术(Sham)组、PF组、ICO 30 mg·kg-1剂量组及ICO 60 mg·kg-1剂量组,每组n=8。单次气管注射博来霉素(BLM,3 mg·kg-1)建立小鼠PF模型。HE及Masson染色观察肺组织病理变化及胶原沉积情况。免疫组化检测肺组织Ⅰ型胶原(collagen Ⅰ)的表达。体外培养肺泡上皮细胞,实验设对照(control)组、表皮生长因子(epidermal growth factor,EGF)组(100 ng·mL-1)及EGF联合ICO(0.1、1、10 mmol·L-1)3个剂量组。免疫荧光法检测细胞E-钙黏蛋白(E-cadherin)和α-平滑肌肌动蛋白(α-SMA)的表达及核因子-κB(NF-κB)p65核转移情况。Western blots检测肺组织和(或)细胞collagen Ⅰ、E-cadherin、α-SMA、Vimentin、磷酸化表皮生长因子受体(phosphorylation epidermal growth factor receptor, p-EGFR)、磷酸化核因子κB抑制物α(p-IκBα)、磷酸化NF-κB p65(p-NF-κB p65)的蛋白水平及NF-κB p65核转移情况。结果 动物实验表明,ICO抑制了BLM诱导的胶原沉积,减少了Ⅰ型胶原的表达,减轻了博来霉素诱导的上皮-间充质转化(epithelial-mesenchymal transition,EMT) (E-cadherin表达增加,Vimentin和α-SMA表达减少),降低了EGFR,IκBα和NF-κB p65 的磷酸化水平并抑制了 NF-κB p65的核转移。细胞实验发现,EGF可激活肺泡上皮细胞EMT和EGFR/NF-κB信号通路,而ICO可逆转这一作用。结论 ICO可能通过抑制EGFR/NF-κB信号通路的活化,逆转了EGF诱导的EMT和博来霉素诱导的小鼠肺纤维化。

OBJECTIVE This study aimed to investigate the role and potential mechanisms of Icotinib (ICO) on pulmonary fibrosis. METHODS C57BL/6 mice were randomly divided into Sham group, PF group, ICO 30 mg·kg-1 group and ICO 60 mg·kg-1 group, 8 rats in each group. A mouse model of PF was induced by intratracheal injection of bleomycin (3 mg·kg-1). Hematoxylin-eosin staining and Masson trichrome staining for lung tissues were performed to observe the pathological alterations and collagen deposition. Immunohistochemical detection of lung tissue collagen type Ⅰ (collagen Ⅰ) expression. In vitro, the lung epithelial cells were divided into control group, epidermal growth factor (EGF) group, EGF combined with ICO (0.1, 1, 10 mmol·L-1) groups. The protein expression of E-cadherin, α-SMA and nuclear transfer of NF-κB p65 were detected by immunofluorescence. The protein levels of Collagen Ⅰ, E-cadherin, α-SMA, Vimentin, phosphorylation epidermal growth factor receptor (p-EGFR), p-IκBα, p-NF-κB p65 and nuclear NF-κB p65 were detected by Western blot analysis in lung tissue and (or) cells. RESULTS The results demonstrated that ICO inhibited bleomycin-induced collagen deposition, reduced type Ⅰ collagen expression, alleviated bleomycin-induced EMT (increased E-cadherin expression and decreased Vimentin and α-SMA expression), and decreased phosphorylation of EGFR, IκBα, NF-κB p65 and nuclear translocation of NF-κB p65 in vivo. Furthermore, incubation of lung epithelial cells with EGF activated EMT and EGFR/NF-κB signaling pathway, and these effects were reversed by ICO In vitro. CONCLUSION In conclusion, ICO attenuates EGF-induced EMT in lung epithelial cells and bleomycin-induced pulmonary fibrosis in mice by downregulating EGFR/NF-κB pathway.

肺纤维化(pulmonary fibrosis,PF)是一种以细胞外基质(extracellular matrix, ECM)过度沉积,气体交换和肺功能受损为特征的慢性、致死性肺部疾病[1]。目前治疗PF的药物主要为吡非尼酮和尼达尼布,但其阻止纤维化进展的效果有限,且伴有不同程度的不良反应,阻碍了其广泛应用。因此,急需新的治疗方法来预防和治疗PF[2]
PF的发病机制尚不明确,目前的研究认为它始于肺损伤后的异常组织修复[3]。肺损伤后,肺泡Ⅱ型上皮细胞通过自我更新和分化为肺泡Ⅰ型上皮细胞参与修复过程[4]。此外,肺泡Ⅱ型上皮细胞通过上皮-间充质转化(epithelial-mesenchymal transition, EMT)获得间充质表型,刺激成纤维细胞活化和分化,并产生大量与肺纤维化相关的ECM分子[5]。而抑制肺泡Ⅱ型上皮细胞EMT的发生,能够减轻PF的发生发展[6]。表皮生长因子受体(epidermal growth factor receptor, EGFR)属于酪氨酸激酶受体家族,研究发现表皮生长因子(epidermal growth factor, EGF)通过EGF/EGFR信号通路可诱导肿瘤细胞发生EMT,从而促进肿瘤细胞的侵袭和转移[7]。而最新研究还发现EGF通过EGFR也可以诱导肺泡Ⅱ型上皮细胞发生EMT[8],但具体机制不清楚。
埃克替尼(icotinib, ICO)是我国自主研发的EGFR-酪氨酸激酶抑制剂,可抑制肿瘤血管生成、增殖和转移,临床用于晚期非小细胞肺癌的治疗[9]。研究发现ICO可抑制非小细胞肺癌A549细胞增殖和EMT[10]。而近期研究还发现ICO对肺动脉高压肺血管重构具有一定的抑制作用[11]。本研究以EMT为切入点,通过体内和体外实验探究ICO对肺纤维化的抑制作用及其机制,为延缓PF的发展提供新的思路和潜在的药物。

HE和Masson染色结果显示,Sham组小鼠肺组织结构完整,肺泡间隔正常,未见明显炎症细胞浸润和蓝色胶原纤维沉积,PF组肺组织结构紊乱,肺泡间隔增厚,并伴有明显的炎症细胞浸润和大量蓝色胶原纤维沉积,而ICO治疗组肺组织病理损伤和胶原纤维沉积均有不同程度减轻。定量分析结果发现,与Sham组相比,PF组肺纤维化程度Ashcroft评分和CVF百分比明显升高(P<0.01),而与PF组相比,ICO治疗组Ashcroft评分和CVF百分比均有不同程度的降低(P<0.01),且ICO高剂量组作用优于ICO低剂量组(图1)。
WB结果显示,与Sham组相比,PF组Ⅰ型胶原蛋白表达显著升高(P<0.01),而与PF组相比,ICO治疗组Ⅰ型胶原蛋白表达均有不同程度的降低(P<0.01),且ICO高剂量组抑制作用优于ICO低剂量组(图2AB)。免疫组化结果显示,与Sham组相比,PF组Ⅰ型胶原阳性表达平均光密度(MOD)显著升高(P<0.01),而与PF组相比,ICO治疗组Ⅰ型胶原阳性表达MOD均有不同程度的降低(P<0.01)(图2CD)。
动物实验结果显示,与Sham组相比,PF组肺泡上皮细胞标志物E-cadherin的表达明显下调而间质细胞标志物α-SMA和Vimentin的表达明显上调(P<0.01)。而与PF组相比,ICO治疗组E-cadherin的表达明显升高而α-SMA和Vimentin的表达明显降低(P<0.05或P<0.01),且ICO高剂量组逆转作用优于ICO低剂量组(图3)。细胞实验结果发现,EGF处理肺泡上皮细胞后,经WB和免疫荧光染色检测发现E-cadherin表达明显降低而α-SMA和(或)Vimentin表达明显升高(P<0.01)。而ICO处理组可明显逆转EGF引起的E-cadherin表达降低和α-SMA、Vimentin表达升高(P<0.05或P<0.01),从而抑制了EMT进程(图4~5)。
动物实验结果所示,与Sham相比,PF组肺组织EGFR、IκBα及NF-κB p65磷酸化水平明显上调、NF-κB p65核转移程度明显增加(P<0.01)。与PF组比较,ICO治疗组p-EGFR、p-IκBα及p-NF-κB p65水平及NF-κB p65核转移程度均不同程度降低(P<0.05或P<0.01)(图6)。体外实验结果所示,与Control组相比,EGF组EGFR、IκBα及NF-κB p65磷酸化水平明显上调、NF-κB p65核转移程度显著增加(P<0.01)。与EGF组相比,ICO(0.1、1、10 mmol·L-1)3个剂量组EGFR、IκBα及NF-κB p65磷酸化水平及NF-κB p65核转移程度均不同程度下降(P<0.05或P<0.01)(图7~8)。
PF是一种以肺泡上皮损伤和胶原生成异常为特征的慢性进行性肺疾病,其发生机制尚不完全清楚,药物对PF的治疗效果也不尽如人意,因此,探究其发病机制、寻找潜在的药物对临床治疗具有重要意义[14]。博来霉素通过引起DNA链断裂和氧化损伤诱导肺损伤,可以复制肺纤维化的病理过程,是目前应用最广泛的动物模型[15]。在本研究中,HE和Masson染色的组织病理学检查显示BLM诱导的小鼠有严重的肺组织结构紊乱,肺泡间隔增厚,并伴有大量胶原纤维沉积;WB和免疫组化实验显示Ⅰ型胶原的表达明显增加,从而验证了模型复制成功。而给药ICO干预后,上述肺组织病理损伤均有所改善,胶原沉积和Ⅰ型胶原的表达水平均降低,从而产生了抗纤维化作用。
EMT是上皮细胞向间充质细胞表型转化的过程,上皮细胞失去原有的接触黏附和极性,获得间充质细胞的侵袭、迁移和产生ECM的特性[16]。大量研究表明EMT在PF发生发展中发挥着重要作用,抑制BLM或TGF-β1诱导的EMT进程能够不同程度缓解PF的进程[6,17]。研究表明,小鼠气管注射博来霉素后可引起肺损伤,持续的损伤可进一步导致炎症细胞分泌TNF-α、TGF-β1、EGF等细胞因子激活成纤维细胞,促进成纤维细胞的增殖与活化,诱导肺泡上皮细胞EMT,促进胶原蛋白的合成而引起ECM合成增加,促使肺纤维化的发生与发展[15]。EGF作为一种生长因子,不仅参加了肿瘤细胞的EMT进程,也参与了肺泡上皮细胞EMT进程[7,18]。而近期的研究表明ICO可抑制A549细胞的EMT进程[10],故本研究采用EGF诱导的肺上皮细胞EMT模型。而本研究发现,ICO不仅对BLM诱导的肺组织EMT进程有明显的抑制作用,对EGF诱导的肺泡上皮细胞EMT进程也有显著的抑制作用(E-cadherin的表达明显升高而α-SMA和Vimentin的表达明显降低)。提示,ICO通过抑制肺泡上皮细胞EMT的发生来减缓肺纤维化的发展。
研究表明,NF-κB信号通路在肾纤维化、肝纤维化、肺纤维化中发挥调控作用,抑制NF-κB信号通路的激活可能是治疗肺纤维化的有效策略[19]。而研究还发现BLM诱导的EMT发生和EGF诱导的肿瘤细胞EMT发生都与NF-κB信号通路活化有关[20-21]。而本研究动物实验发现,ICO能够抑制BLM诱导的EGFR、IκBα和NF-κB p65的磷酸化,抑制NF-κB p65的核转移。体外实验也发现,ICO能够降低EGF诱导的EGFR、IκBα和NF-κB p65的磷酸化水平,抑制NF-κB p65的核转移,进而影响了下游靶基因E-cadherin、α-SMA和Vimentin的表达。因此,我们推测ICO可能通过阻断EGFR、抑制NF-κB信号通路的活化而产生抗纤维化作用。
综上所述,EGF/NF-κB信号通路调控了肺泡上皮细胞EMT的发生,ICO可能通过抑制EGF/NF-κB信号通路的活化,逆转肺泡上皮细胞EMT进程而改善了肺纤维化,为进一步应用ICO治疗肺纤维化提供新的思路。
