摘要:
目的 探讨新城疫病毒(Newcastle disease virus, NDV)毒株FMW(NDV/FMW)对恶性黑色素瘤维罗非尼(vemurafenib)耐药细胞株WM3248/vemurafenib免疫原性死亡相关分子表达的影响。方法 通过病毒滴度检测考察病毒复制情况;采用CCK8试剂盒检测细胞存活率;Western印迹法检测细胞凋亡蛋白、细胞和上清液中高迁移率族蛋白1(HMGB1)和热休克蛋白90(HSP90)变化;流式细胞术和激光共聚焦技术检测细胞膜上钙网蛋白(calreticulin, CRT)的表达;荧光素酶法检测细胞上清液中的三磷酸腺苷(ATP)的释放。结果 NDV/FMW在WM3248/vemurafenib细胞株内复制,降低耐药细胞存活率并增加细胞凋亡(P<0.001);NDV/FMW诱导WM3248/vemurafenib细胞膜CRT表达增加(P<0.01),ATP分泌、HMGB1和HSP90释放(P<0.05)。结论 NDV/FMW促进WM3248/vemurafenib细胞株死亡,免疫原性死亡是其死亡机制之一。

Abstract:
Objective To investigate the effects of Newcastle disease virus (NDV) strain FMW (NDV/FMW) on the expression of immunogenic cell death-related molecules in vemurafenib-resistant malignant melanoma WM3248/vemurafenib cells. Methods Human melanoma WM3248 and WM3248/vemuragenib cells were treated with NDV/FMW. Multi-step viral growth curves was used to detect virus yield; cell viability was detected by CCK8; the changes of apoptosis-related proteins and the secretion of high mobility group protein 1 (HMGB1) and heat shock protein 90 (HSP90) in the supernatant were detected by Western blotting; flow cytometry and laser copolymerization were used to detect the expression of calreticulin (CRT) on cell membrane; the release of adenosine triphosphate (ATP) in the supernatant was tested by fluorescein enzymatic method. Results NDV/FMW was duplicated in WM3248/vemurafenib cells, inhibited cell viability and promoted apoptosis (P<0.001). NDV/FMW enhanced the accumulation of CRT (P<0.01) on the cell surface and promoted the secretion of ATP, HMGB1 and HSP90 in WM3248/vemurafenib cells (P<0.05). Conclusion NDV/FMW can induce the death of WM3248/vemurafenib cells, and the immunogenic cell death is one of the mechanisms of cell death.
