Our studies were aimed to explore the effect and mechanism of the inhibition of the formation of vasculogenic mimicry (VM) in human glioblastoma cells by Xihuang pill (XHP) medicated serum through regulating the hypoxia inducible factor-1α (HIF-1α)/vascular endothelial growth factor A (VEGFA)/vascular endothelial growth factor receptor 2 (VEGFR2) signaling pathway. The medicated serum of XHP was prepared by gavage for 7 days to male SD rats (approval number of animal experiment ethics: 202105A051). The hypoxia model of U251 cells was established using 200 μmol·L-1 of CoCl2. After treatment with XHP-medicated serum, cell viability and proliferation of U251 cells were detected by CCK-8 and cell cloning experiment. Cell apoptosis and cell cycle of U251 cells were determined by flow cytometry. Cell migration and invasion were evaluated by wound healing and Transwell invasion assay. The formation of VM was assessed by three-dimensional cell culture of U251 cells. The protein expression levels of HIF-1α, VEGFA, VEGFR2, phosphorylated-VEGFR2 (p-VEGFR2), vascular endothelial-cadherin (VE-cadherin), Eph receptor tyrosine kinases A2 (EphA2), matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 14 (MMP14) and laminin γ2 in U251 cells were detected by Western blot. The results showed that 10% XHP-medicated serum had little effect on the cell viability, proliferation, apoptosis and cell cycle of U251 cells under hypoxia. Compared with the model group, 10% XHP-medicated serum at 1.0, 1.5 and 2.0 h significantly decreased the migration rate (P < 0.01) and the number of invading U251 cells (P < 0.01). 10% XHP-medicated serum at 2.0 h significantly suppressed the formation of VM tubular structures in U251 cells under the condition of hypoxia (P < 0.01). Western blot experiment showed that 10% XHP-medicated serum significantly down-regulated the expression of HIF-1α, VEGFA, phospho-VEGFR2, VE-cadherin, EphA2 and MMP14 proteins (P < 0.05). In conclusion, XHP could inhibit the formation of VM in human glioblastoma U251 cells to suppress the angiogenesis by down-regulating the HIF-1α/VEGFA/VEGFR2 signaling pathway.

探究西黄丸含药血清调控低氧诱导因子1α (hypoxia inducible factor-1α, HIF-1α)/血管内皮生长因子A (vascular endothelial growth factor A, VEGFA)/血管内皮生长因子受体2 (vascular endothelial growth factor receptor 2, VEGFR2) 信号通路, 抑制脑胶质瘤细胞血管生成拟态(vasculogenic mimicry, VM) 形成的作用及机制。采用对雄性SD大鼠连续灌胃给药7天,制备西黄丸含药血清(动物实验伦理审批号: 202105A051)。采用200 μmol·L-1 CoCl2构建U251细胞低氧模型, 给予西黄丸含药血清后, CCK-8法、细胞克隆实验检测U251细胞活力和增殖情况; 流式细胞术检测U251细胞凋亡及周期; 细胞划痕愈合、Transwell侵袭实验检测U251细胞的迁移与侵袭能力; 3D细胞培养检测U251细胞VM的形成情况; Western blot法检测U251细胞HIF-1α、VEGFA、VEGFR2、磷酸化VEGFR2 (phosphorylated-VEGFR2, p-VEGFR2)、血管内皮钙黏着蛋白(vascular endothelial-cadherin, VE-cadherin)、Eph受体酪氨酸激酶A2 (Eph receptor tyrosine kinases A2, EphA2)、基质金属蛋白酶2 (matrix metalloproteinase 2, MMP2)、基质金属蛋白酶14 (matrix metalloproteinase 14, MMP14) 和层黏连蛋白γ2 (laminin γ2) 等蛋白表达水平。结果显示, 低氧状态下, 10%西黄丸含药血清对U251细胞活力、增殖、凋亡和细胞周期影响较小。与低氧模型组相比, 10% 1.0、1.5和2.0 h组西黄丸含药血清均显著减慢U251细胞的迁移速率(P < 0.01), 显著减少侵袭的U251细胞数量(P < 0.01)。10% 2.0 h组西黄丸含药血清显著抑制低氧状态下U251细胞的VM管状结构形成(P < 0.01)。Western blot实验显示, 10%西黄丸含药血清显著下调HIF-1α、VEGFA、phospho-VEGFR2、VE-cadherin、EphA2、MMP14等蛋白表达(P < 0.05)。综上所述, 西黄丸可通过下调HIF-1α/VEGFA/VEGFR2信号通路, 抑制脑胶质瘤U251细胞VM形成, 发挥抗血管生成的作用。

Our studies were aimed to explore the effect and mechanism of the inhibition of the formation of vasculogenic mimicry (VM) in human glioblastoma cells by Xihuang pill (XHP) medicated serum through regulating the hypoxia inducible factor-1α (HIF-1α)/vascular endothelial growth factor A (VEGFA)/vascular endothelial growth factor receptor 2 (VEGFR2) signaling pathway. The medicated serum of XHP was prepared by gavage for 7 days to male SD rats (approval number of animal experiment ethics: 202105A051). The hypoxia model of U251 cells was established using 200 μmol·L-1 of CoCl2. After treatment with XHP-medicated serum, cell viability and proliferation of U251 cells were detected by CCK-8 and cell cloning experiment. Cell apoptosis and cell cycle of U251 cells were determined by flow cytometry. Cell migration and invasion were evaluated by wound healing and Transwell invasion assay. The formation of VM was assessed by three-dimensional cell culture of U251 cells. The protein expression levels of HIF-1α, VEGFA, VEGFR2, phosphorylated-VEGFR2 (p-VEGFR2), vascular endothelial-cadherin (VE-cadherin), Eph receptor tyrosine kinases A2 (EphA2), matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 14 (MMP14) and laminin γ2 in U251 cells were detected by Western blot. The results showed that 10% XHP-medicated serum had little effect on the cell viability, proliferation, apoptosis and cell cycle of U251 cells under hypoxia. Compared with the model group, 10% XHP-medicated serum at 1.0, 1.5 and 2.0 h significantly decreased the migration rate (P < 0.01) and the number of invading U251 cells (P < 0.01). 10% XHP-medicated serum at 2.0 h significantly suppressed the formation of VM tubular structures in U251 cells under the condition of hypoxia (P < 0.01). Western blot experiment showed that 10% XHP-medicated serum significantly down-regulated the expression of HIF-1α, VEGFA, phospho-VEGFR2, VE-cadherin, EphA2 and MMP14 proteins (P < 0.05). In conclusion, XHP could inhibit the formation of VM in human glioblastoma U251 cells to suppress the angiogenesis by down-regulating the HIF-1α/VEGFA/VEGFR2 signaling pathway.

脑胶质瘤起源于神经胶质细胞, 是较常见的高度侵袭性恶性脑肿瘤, 具有发展迅速、预后差、死亡率高等特点。临床上, 脑胶质瘤治疗主要为手术和术后辅助放化疗, 但是多数患者对传统治疗方法不敏感, 预后较差[1-3]。目前, 脑胶质瘤的治疗策略主要包括诱导细胞凋亡和抗血管生成, 进而抑制肿瘤增殖和转移两方面。血管生成拟态(vasculogenic mimicry, VM) 是恶性肿瘤早期适应缺氧, 不依赖于传统血管内皮细胞的肿瘤细胞自身形态改变, 结合细胞外基质重塑形成的新型血管样结构, 这标志着肿瘤血管形成的开始。脑胶质瘤恶化过程中存在着VM形成现象, 且肿瘤恶性程度越高, VM进展越快、现象越显著[4, 5]。研究表明, 低氧诱导因子1α (hypoxia inducible factor-1α, HIF-1α)/血管内皮生长因子A (vascular endothelial growth factor A, VEGFA)/血管内皮生长因子受体2 (vascular endothelial growth factor receptor 2, VEGFR2) 信号通路在促进脑胶质瘤VM形成中起重要作用, 低氧环境可上调胶质瘤细胞HIF-1α和VEGF蛋白表达, 诱导VM形成[5-11]
西黄丸始载于《外科证治全生集》, 由牛黄、麝香、乳香、没药组成, 具有清热解毒、活血祛瘀和化结散痈之功, 临床上常用于恶性肿瘤的辅助治疗[12]。西黄丸可改善脑胶质瘤患者的临床症状, 提高生活质量[13]。研究表明, 西黄丸通过抑制U87细胞中丝氨酸苏氨酸蛋白激酶(protein kinase B, PKB, Akt)/哺乳类动物雷帕霉素靶点(mammalian target of rapamycin, mTOR)/头框转录因子O亚族1 (FOXO1) 信号通路从而促进细胞凋亡[14]。亦有研究证明, 西黄丸及主要药味麝香和牛黄通过抑制人前列腺癌PC-3细胞中异常激活的磷脂酰肌醇-3激酶(phosphatidylinositol 3-kinase, PI3K)/Akt/mTOR信号通路, 促进细胞凋亡, 抑制PC-3荷瘤小鼠的皮下移植瘤生长的作用[15]。此外, 西黄丸含药血清显著促进乳腺癌细胞株MDA-MB-231、MDA-MB-435和MCF-7细胞凋亡, 抑制细胞增殖和迁移[16, 17]
本课题组前期研究发现, 西黄丸可显著诱导U251和U87细胞凋亡, 抑制裸鼠异位移植瘤生长, 协同增强替莫唑胺的抗胶质瘤作用[18]。然而, 西黄丸是否可通过调控HIF-1α/VEGFA/VEGFR2信号通路, 抑制脑胶质瘤细胞VM形成尚不清晰。故本文拟构建U251细胞低氧模型, 研究西黄丸含药血清调控HIF-1α/VEGFA/VEGFR2信号通路对VM形成的影响, 旨在探究西黄丸对脑胶质瘤抗血管生成治疗的作用及其机制, 为临床中西药联合抗胶质瘤血管生成提供依据。

统计学分析  采用GraphPad 8.0统计学软件对实验结果进行统计学分析。计量资料以x± s表示。各组分别与低氧对照组进行单因素方差分析, 以P < 0.05为差异有统计学意义。
低氧状态下, 不同时间点西黄丸含药血清及其不同百分比含量作用U251细胞48 h的细胞活力测定结果如图 1A所示。结果显示, 当含药血清浓度为5%时, 1.0 h组西黄丸含药血清可以抑制U251细胞活力(P < 0.05)。当含药血清浓度为10%时, 1.5和2.0 h西黄丸含药血清可以抑制U251细胞活力(P < 0.01); 其中, 2.0 h西黄丸含药血清对U251细胞的抑制作用最强, 为93.2% ± 3.6%。故选用10%含药血清作用U251细胞48 h为条件进一步探究其作用机制。
低氧状态下, 10%不同时间点西黄丸含药血清作用U251细胞48 h的克隆增殖测定结果如图 1BC所示。结果显示, 与对照组相比, 低氧对U251细胞增殖有抑制作用(P < 0.01); 与低氧模型组相比, 1.5和2.0 h西黄丸含药血清对U251细胞增殖呈下调趋势, 但无统计学差异。结果表明, 西黄丸含药血清对U251细胞活力及增殖影响作用较小。
低氧状态下, 不同时间点西黄丸含药血清对U251细胞凋亡和细胞周期的影响结果如图 2所示。结果显示, 对照组细胞形态正常, 几乎无凋亡和坏死细胞。CoCl2低氧对U251细胞凋亡及细胞周期几无影响。给予浓度为10%的1.0、1.5和2.0 h时间点西黄丸含药血清处理48 h后, U251细胞的总凋亡率分别为2.23%、2.69%和3.94%, 且G1期的细胞数量分别从46.2%增加到47.0%、48.8%和52.9%。与低氧模型组相比, 1.5和2.0 h组西黄丸含药血清能提高U251细胞总凋亡率(P < 0.01)。其中, 2.0 h组西黄丸含药血清能提高细胞晚期凋亡水平(P < 0.01), 并使细胞增殖阻滞在G1期(P < 0.01)。结果表明, 西黄丸含药血清对U251细胞凋亡及细胞周期影响较小。
低氧状态下, 10%不同时间点西黄丸含药血清作用U251细胞48 h的细胞迁移能力测定结果如图 3AB所示。结果显示, 与对照组相比, 当划痕48 h时, 低氧对U251细胞迁移能力有显著的诱导作用(P < 0.01)。与低氧模型组相比, 当划痕24 h时, 1.5和2.0 h西黄丸含药血清显著抑制了U251细胞的迁移能力(P < 0.01); 当划痕48 h时, 1.0、1.5和2.0 h西黄丸含药血清均对U251细胞的迁移能力有显著的抑制作用(P < 0.01)。
低氧状态下, 10%不同时间点西黄丸含药血清作用U251细胞48 h的细胞侵袭能力测定结果如图 3AC所示。结果显示, 与对照组相比, 低氧对U251细胞侵袭能力有显著的抑制作用(P < 0.01); 与低氧模型组相比, 1.0、1.5和2.0 h西黄丸含药血清均显著抑制了U251的侵袭能力(P < 0.01)。
结果表明, 西黄丸含药血清可显著抑制U251细胞的迁移与侵袭能力, 抑制U251细胞转移。
低氧状态下, 10% 2.0 h西黄丸含药血清对U251细胞中VM形成影响结果如图 4所示。结果显示, 与常氧对照组相比, 低氧模型组所形成的VM结构数量显著增加(P < 0.01), 表明低氧环境能显著促进U251细胞中VM形成。与低氧模型组相比, 2.0 h西黄丸含药血清作用1、3、6和12 h后均显著抑制了U251细胞VM形成(P < 0.01), 促使基质胶中已形成的VM管网样结构断裂溃散并使形成VM结构的U251细胞皱缩成团直至死亡。结果表明, 西黄丸含药血清可显著抑制U251细胞中VM形成。
图 5所示, 低氧显著上调U251细胞中HIF-1α和VEGF蛋白表达(P < 0.01)。给予10%不同时间点西黄丸含药血清处理48 h后, 细胞中HIF-1α和VEGFA蛋白表达显著下调。
图 6所示, 低氧对U251细胞中VEGFR2和p-VEGFR2蛋白表达无明显影响。给予10%不同时间点西黄丸含药血清处理48 h后, 含药血清对细胞中VEGFR2蛋白表达无明显影响; 1.5和2.0 h组西黄丸含药血清显著下调细胞中p-VEGFR2蛋白的表达(P < 0.05)。
图 7所示, 低氧显著上调U251细胞中VE-cadherin、MMP14、laminin γ2蛋白表达(P < 0.05)。给予10%不同时间点西黄丸含药血清处理48 h后, 1.0 h组西黄丸含药血清显著上调细胞中EphA2蛋白的表达(P < 0.05); 1.5 h组西黄丸含药血清显著下调细胞中VE-cadherin (P < 0.01)、EphA2 (P < 0.05)、MMP14 (P < 0.05) 蛋白的表达; 2.0 h组西黄丸含药血清显著下调了细胞中MMP14蛋白的表达(P < 0.05); 而与低氧模型组相比, 西黄丸含药血清对细胞中active-MMP2/pro-MMP2比值和laminin γ2表达无明显影响。结果表明, 西黄丸含药血清可能通过调节U251细胞中HIF-1α/VEGFA/VEGFR2通路相关蛋白, 抑制VM形成从而发挥抗胶质瘤作用。
在前期研究结果基础上, 本研究确定西黄丸含药血清作用48 h为后续给药时间。CCK-8、细胞克隆、细胞凋亡和细胞周期测定结果显示, 西黄丸含药血清对U251细胞的活力、增殖、凋亡与周期影响较小。
划痕愈合与Transwell侵袭实验结果表明, 西黄丸含药血清对U251细胞的迁移与侵袭能力有显著抑制作用; 3D细胞培养下血管生成拟态实验结果表明2.0 h组西黄丸含药血清对U251细胞VM形成有显著抑制作用, 能破坏基质胶中已形成VM结构并促使形成VM的U251细胞皱缩成团; 可见西黄丸含药血清对脑胶质瘤的转移与侵袭能力有一定的抑制作用。研究[19, 20]表明低氧环境下, 肿瘤细胞侵袭和运动性增强。然而本研究中, CoCl2诱导的低氧环境下U251细胞的侵袭能力相较于常氧环境低, 侵袭细胞数减少, 推测其原因可能为本研究选用化学诱导剂CoCl2诱导低氧, 短时间内对细胞产生一定的损伤(预实验选取了200μmol·L-1 CoCl2, 细胞增殖抑制率为7.56%), 在低氧初期细胞侵袭能力有所降低。后续将采用低氧工作站对此进行进一步验证。
Western blot实验结果表明, 西黄丸含药血清对U251细胞中VM形成的抑制作用与下调HIF-1α、VEGFA、p-VEGFR2、VE-cadherin、EphA2、MMP14等蛋白表达存在密切关系。研究表明, HIF-1α/VEGF通路可以介导VM形成, 是导致脑胶质瘤患者治疗过程中抗血管生成方面治疗效果不佳的重要机制[5, 21, 22]。Duan[5]研究中发现低氧增加人脑胶质瘤U87细胞中HIF-1α、VEGF表达和诱导VM形成。Jiang等[6]研究也证明低氧增加人脑胶质瘤T98G细胞和原代培养人脑胶质瘤干细胞中HIF-1、VEGFA、p-VEGFR2表达和诱导VM形成。HIF-1是介导肿瘤细胞对低氧微环境进行适应性反应的关键性转录调控因子, 是肿瘤微血管形成机制中的“中枢”。HIF-1由一个αβ亚单位组成; 低氧微环境下, 细胞内低氧感应器脯氨酰羟化酶(prolyl hydroxylase, PHD) 活性降低, HIF-1α羟基化受阻, 允许HIF-1α逃避p-VHL蛋白(von Hippel-Lindau protein) 介导的泛素化降解, 胞浆内HIF-1α积聚并转移入核, 与HIF-1β结合形成异二聚体, 随后与靶基因缺氧反应元件结合, 激活靶基因。VEGF是促进肿瘤VM和血管生成的关键调节因子, 也是HIF-1调控的重要靶基因。VEGF家族主要分为VEGFA、-B、-C、-D以及胎盘生长因子(placenta growth factor, PIGF) 等亚型; 其中, VEGFA在血管形成中发挥重要作用。VEGFs通过与其受体VEGFRs结合后, 胞内激酶区构象改变, 产生激酶活性催化底物蛋白磷酸化, 最终通过信号级联反应产生生物效应; 其中, HIF-1α/VEGFA/VEGFR2信号通路在促进脑胶质瘤VM形成中起重要作用[6-11]。Yao等[7]研究发现, 脑胶质瘤干细胞样细胞中VEGFR2、VE-cadherin、EphA2表达增高, VM形成明显增加。有研究表明, VE-cadherin、EphA2、MMP14、MMP2及laminin5γ2与VM形成密切相关[22-25]。VE-cadherin激活MMPs是VM形成的关键通路[22]。MMPs涉及多种促进肿瘤进展的机制, MMP2和MMP14被发现与肿瘤VM形成密切相关, MMP2对细胞外基质有强烈的蛋白水解作用, MMP14通过与金属蛋白酶组织抑制因子2形成复合体, 激活前体MMP2促进IV胶原降解。VM形成起始阶段, 侵袭的癌细胞可能失去细胞间黏附, 其运动性增加并分泌MMPs溶解基底膜[26, 27]。同时, MMPs将laminin5γ2分割成γ2′和γ2x, 是VM形成的最终步骤[22]。在本研究中, 西黄丸含药血清对细胞中VEGFR2、lamininγ2蛋白表达和active-MMP2/pro-MMP2比值有一定下调作用, 但无统计学差异, 研究结果与以上研究结果相符。
低氧模型组部分通路蛋白相较于常氧对照组未能上调, 其可能原因为文献[4, 6, 25]采用低氧工作站造模, 本研究选择化学诱导剂CoCl2 (200 μmol·L-1) 建立低氧模型, 两种造模方法不同。CoCl2造模条件下, 低氧环境显著上调HIF-1α、VEGFA、VE-cadherin、MMP14及laminin γ2等蛋白表达, VEGFR2和EphA2蛋白表达有一定上调趋势, 但对p-VEGFR2和active-MMP2/pro-MMP2比例几无影响。Yao等[7]研究发现, 低氧状态下, 胶质瘤细胞VEGFR2蛋白表达显著上调, 促进VM形成。Jiang等[6]研究进一步发现人脑胶质瘤T98G细胞在低氧环境中, p-VEGFR2蛋白表达显著增加。然而, 近期McClellan等[28]研究表明与常氧组相比, 低氧组p-VEGFR2蛋白表达量无明显变化。本研究中, 低氧状态上调VEGFR2蛋白表达, 促进VM形成, 但未上调p-VEGFR2蛋白, 与文献[28]报道相一致, 推测在化学诱导剂CoCl2建立的低氧模型中, VEGFR2蛋白表达上调, 但对p-VEGFR2蛋白表达影响较小, 其具体作用机制仍需要进一步研究。Zhang等[29]研究中探究了不同浓度CoCl2模拟缺氧对HK2、786-0和HMEC-1细胞中MMPs表达水平的影响, HMEC-1细胞中MMP2表达量随CoCl2浓度增加呈剂量依赖性降低。在本研究中, 低氧状态仅轻微下调active-MMP2/pro-MMP2比例, 无统计学差异, 与文献[29]报道存在差异, 推测在化学诱导剂CoCl2建立的低氧模型中, MMP2表达量变化与具体细胞系相关, 后续将在脑胶质瘤U87细胞系中进一步探究。
综上所述, 西黄丸含药血清可以抑制HIF-1α/VEGFA/VEGFR2通路, 下调该通路主要活性蛋白表达, 抑制U251细胞的迁移与侵袭能力从而发挥抗脑胶质瘤VM形成的作用。本文是基于体外实验研究西黄丸抗脑胶质瘤VM形成的作用及其机制, 存在一定的局限性, 后续将继续开展体内实验, 为该作用机制提供更可靠的支撑。同时, 本研究将对西黄丸含药血清中具体发挥药理作用的成分及含量进行测定, 丰富其物质理论基础。目前, 已完成其主要成分没药中单体成分没药甾酮对VM形成影响的探究。
