Abstract
本发明公开了KIAA1429在制备吉非替尼抗非小细胞肺癌增敏剂中的应用。本发明以具有吉非替尼耐药特征的非小细胞肺腺癌细胞株HCC827为实验对象,发现当靶向下调KIAA1429,可提高HCC827耐药株对吉非替尼的敏感性;进一步实验表明KIAA1429主要通过激活JNK通路发挥耐药作用,即KIAA1429通过阻断吉非替尼对JNK通路的抑制,导非小细胞肺腺癌的耐药。通过降低KIAA1429的表达水平,可以恢复吉非替尼通过JNK通路发挥抑制肿瘤细胞活性的作用;表明可通过降低肿瘤细胞中KIAA1429的表达水平,增强吉非替尼抗非小细胞肺癌的敏感性和功效,最终改善或治疗对吉非替尼耐药的非小细胞肺腺癌。
Description
技术领域
本发明涉及生物医药技术领域,更具体地,KIAA1429在制备吉非替尼抗非小细胞肺癌增敏剂中的应用,尤其是涉及KIAA1429的表达抑制剂在制备吉非替尼抗非小细胞肺癌增敏剂中的应用。
背景技术
根据2018年全球癌症数据统计显示,肺癌是人群中发生率最高的癌症,且死亡率居肿瘤死亡率的榜首。80%的肺癌病理类型为非小细胞肺癌(Non-small cell lungcancer,NSCLC),而肺腺癌是非小细胞肺癌中最常见的病理类型。肺腺癌以手术治疗、放射治疗和药物治疗为主。然而这些方法都有一定的局限性,受到不同因素的制约。目前,医治肺腺癌最有效的方法是手术治疗,但由于肺腺癌诊断难度较大,较多患者在肺腺癌晚期才得以确诊,往往已经错过最佳的治疗时期。
吉非替尼(Gefitinib,Iressa,伊瑞可,易瑞沙)是一种口服表皮生长因子受体酪氨酸激酶抑制剂(EGFR-TKI,属小分子化合物)。对EGFR-TK的抑制可阻碍肿瘤的生长、转移和血管生成,并增加肿瘤细胞的凋亡。其适用于治疗既往接受过化学治疗的局部晚期或转移性NSCLC。但其作为靶向药,唯一避免不了就是出现耐药。据临床观察,吉非替尼平均耐药时间大概为1年。因此,针对肺腺癌对吉非替尼耐药的分子机制研究,对于辅助临床治疗至关重要,且有必要研究以降低肺腺癌细胞增殖、转移和侵袭能力为目标的新生物药。
KIAA1429是分子量最大的m6A甲基化转移酶,将METTL3、METTL14、WTAP和被修饰的RNA底物相连接,其作用相当于甲基化转移酶复合物的支架,主要通过影响复合物的结构,调控着整个修饰过程。KIAA1429还可以影响RNA转录和翻译的过程、基因表达的转录过程,以及引起细胞出现增殖缺陷,最终导致癌症发生。在肝癌研究中发现,KIAA1429可以通过诱导信mRNA前体(Precursor messenger ribonucleic acid,pre-mRNA)发生m6A甲基化修饰,导致其与结合蛋白分离而降解,最终驱使肝癌发生恶化和转移。在乳腺癌中,KIAA1429也发挥了致癌作用。KIAA1429通过靶向调控CDK1的表达促进乳腺癌的恶化,当药物结合二者使期表达降低时,乳腺癌的治疗效果明显改善。不仅如此,KIAA1429在胃癌组织中的表达水平较癌旁组织更高,抑制KIAA1429表达后,胃癌细胞增殖能力下降;上调其修饰的下游靶基因JUN原癌基因(Jun proto-oncogene,Jun)后,增殖活性恢复,提示KIAA1429通过提高下游靶基因Jun的m6A修饰水平,促进胃癌的进展;不仅如此,KIAA1429也会受lncRNA调控后,影响肿瘤细胞的糖酵解过程,从而促进胃癌的恶化。KIAA1429的致癌作用在骨瘤、结直肠癌、前列腺癌中均有所发现,且KIAA1429的表达除受上游miRNA或lncRNA的调控之外,其自身也可以独立调控下游mRNA的表达。
综上所述,m6A甲基化修饰与癌症发展过程有密切关系,但m6A甲基化转移酶KIAA1429在非小细胞肺腺癌中的吉非替尼耐药机制,目前尚无任何研究。

实施例1 HCC827及吉非替尼耐药的HCC827细胞株对吉非替尼敏感性验证
细胞活性检测(MTS实验):分别取对数生长期细胞(HCC827非小细胞肺腺癌细胞株、HCC827/Gefitinib非小细胞肺腺癌吉非替尼耐药细胞株)接种于96孔板内,细胞密度为3×105个/mL,每孔加入100μL细胞悬液。经过夜贴壁,将吉非替尼在DMSO中溶解,共有2,6,10,40,60μM共5个剂量组,同时设置阴性对照组,每组6个副孔。染毒24小时后,弃上清,100μL PBS清洗细胞,加入100μL MTS应用液(每5份体积完全培养基加入1份体积MTS),继续培养2小时。最后用酶标仪测定450nm处各孔吸光值(absorbance,A),计算出细胞活力。计算公式为:细胞活力(%)=[A(处理组)-A(培养基组)]/[A(阴性对照组)-A(培养基组)]×100%,同时对各细胞的剂量-活性关系进行拟合,得出受试物对各细胞的半数抑制浓度(IC50)。

②蛋白变性:根据所测得的蛋白样品浓度,分别加入适量的RIPA裂解液以调整蛋白样品浓度为2.5μg/μL,并按4体积的蛋白加入1体积的5×Loading buffer。涡旋混匀后瞬离,在金属浴中100℃变性10min,-80℃冰箱保存。
③电泳:清洁烘干玻璃板后,将长板置于外侧,短板置于内侧,确保底面平齐,用楔子固定并封闭玻璃板底部,检查两面夹紧后开始灌胶。配制含有8%丙烯酰胺的分离胶,充分混匀后,灌入玻璃板至指定位置,使用异丙醇液封以促进分离胶聚合。室温静置40min,使分离胶充分凝固。弃除异丙醇并用去离子水清洗后,将混合均匀的4%丙烯酰胺的浓缩胶灌入玻璃板,去除边缘气泡后小心插入梳子,用夹子固定,室温静置40min。待浓缩胶充分凝固。组装好电泳设备,倒入电泳缓冲液,垂直向上拔出梳子,每孔蛋白样品上样10μL,蛋白Marker上样5μL。连接电源后,设置电压为60V,30min后更改电压为95V,继续电泳1.5h,待蓝紫色条带电泳出底端可终止电泳。
④转膜:将配制的电转缓冲液置于4℃冰箱预冷。将待用的海绵、滤纸浸泡于电转缓冲液中备用。裁剪一张适当大小的PVDF膜浸泡于甲醇1min,使其活化。电泳完毕后,切好胶置于电转液中浸泡5min。按从正极到负极依次是海绵、3张滤纸、PVDF膜、凝胶、3张滤纸、海绵,制备“三明治胶”,应保持各层湿润且无气泡。将对应的正负极插入转膜槽中,加入足量的电转缓冲液,连接电源,设置电压为100V,转膜时间约为1.5h。
⑤免疫反应:将转膜完毕的PVDF膜做好标记后,浸泡在5%脱脂奶粉中,在摇床室温封闭2h。一抗孵育:用TBST洗涤PVDF膜三次,每次10min。将一抗用TBST溶液稀释至1:500,内参β-ACTIN稀释至1:1000。将PVDF膜置于抗体液中孵育1h后,转入4℃冰箱过夜。二抗孵育:用TBST在摇床上洗涤PVDF膜三次,每次10min。用TBST将二抗稀释至1:5000。将PVDF膜置于抗体液中室温孵育2h。用TBST洗涤三次,每次10min。
⑥化学发光显影:在避光条件下,吸取ECL发光液A液和B液各1mL并混合均匀,将PVDF膜浸泡在发光混合液中,反应1~2min,然后将PVDF膜移至荧光图像分析系统的平板上,再放入荧光图像分析系统显影区。待出现清晰的蛋白条带后可终止显影,保存条带图像。
⑦凝胶成像分析:用ImageJ软件对目的条带和内参条带进行定量分析,蛋白表达水平为目的条带定量结果/内参条带定量结果。

实施例3吉非替尼对稳转KIAA1429低表达的耐药株HCC827细胞活性的影响。
S1.同实施例1,找出稳转KIAA1429低表达的耐药株HCC827的吉非替尼的IC50(8.91μM)。以该吉非替尼药物浓度为后续研究使用浓度(图3中A)。
S2.使用取对数生长期的sh-NC和sh-KIAA1429组细胞接种于96孔板内,设置sh-NC对照组,sh-KIAA1429对照组,sh-NC吉非替尼处理组,sh-KIAA1429吉非替尼处理组,细胞密度为3×105个/mL,每孔加入100μL细胞悬液。经过夜贴壁,将吉非替尼在DMSO中溶解,配制为9.00μM浓度进行染毒,染毒24小时后,弃上清,100μL PBS清洗细胞,加入100μL MTS应用液(每5份体积完全培养基加入1份体积MTS),继续培养2小时。最后用酶标仪测定450nm处各孔吸光值(absorbance,A),计算出细胞活力。计算公式为:细胞活力(%)=[A(处理组)-A(培养基组)]/[A(阴性对照组)-A(培养基组)]×100%,得出受试物对各细胞活性的抑制作用。
结果如图3所示,与sh-NC对照组的吉非替尼用药效果相比,吉非替尼对sh-KIAA1429组的细胞活性抑制更为明显(图3中B),表明通过靶向下调吉非替尼耐药特征的非小细胞肺腺癌细胞株HCC827中的KIAA1429,可以提高HCC827耐药株对吉非替尼的治疗敏感性。
实施例4 KIAA1429主要通过激活JNK通路发挥耐药作用
同实施例3的分组方式,将细胞接种于6孔板,同实施例2步骤S5收集蛋白进行Western blot实验。检测JNK、P38、ERK、和MEK四个通路的关键蛋白。
结果如图4所示,仅发现JNK通路上的关键蛋白(p-JNK、JNK)在KIAA1429敲减后,吉非替尼处理可显著抑制上述蛋白的表达,提示m6A甲基化转移酶KIAA1429通过阻断吉非替尼对JNK通路的抑制,导致非小细胞肺腺癌的耐药。而本发明通过降低m6A甲基化转移酶KIAA1429的表达水平,可以恢复吉非替尼通过JNK通路发挥抑制肿瘤细胞活性的作用。表明可通过降低肿瘤细胞中KIAA1429的表达水平,增强吉非替尼抗非小细胞肺癌的敏感性和功效,最终改善或治疗对吉非替尼耐药的非小细胞肺腺癌。
