目的:探讨mTOR调节相关蛋白(regulatory-associated protein of mTOR,RAPTOR)对口腔鳞状细胞癌(oral squamous cell carcinoma,OSCC)迁移、侵袭和增殖能力的影响。方法:利用TCGA生物信息数据库查询在头颈部鳞状细胞癌(head and neck squ...目的:探讨mTOR调节相关蛋白(regulatory-associated protein of mTOR,RAPTOR)对口腔鳞状细胞癌(oral squamous cell carcinoma,OSCC)迁移、侵袭和增殖能力的影响。方法:利用TCGA生物信息数据库查询在头颈部鳞状细胞癌(head and neck squamous cell carcinoma,HNSCC)组织与癌旁组织中差异表达的mRNA。Western blot检测RAPTOR在人口腔上皮细胞HOEC和OSCC细胞系中的表达。利用伤口愈合实验、Transwell实验、EdU实验检测各组细胞迁移、侵袭及增殖能力。生物信息学网站预测与RAPTOR靶向结合的微小RNA(microRNA,miR)。功能学实验验证miR-485-5p是否可以靶向RAPTOR影响OSCC细胞的迁移、侵袭和增殖。结果:RAPTOR在HNSCC组织中较癌旁组织表达增高。伤口愈合、Transwell和EdU实验结果示,RAPTOR有促进OSCC细胞的迁移、侵袭和增殖能力。miR-485-5p能与RAPTOR靶向结合,且miR-485-5p上调能逆转RAPTOR促进CAL27细胞迁移、侵袭和增殖能力。结论:miR-485-5p通过靶向RAPTOR抑制OSCC细胞迁移、侵袭和增殖能力。展开更多

Despite government efforts, many still prefer motorized transport, citing mobility and safety concerns, exacerbated by insufficient pedestrian infrastructure. This study examines the motivations behind this reliance on motorized vehicles, particularly motorcycles, in Hanoi. Findings reveal safety and convenience as primary factors driving motorized transport use, especially for accessing bus stations. Economic incentives could promote non-motorized travel and public transport adoption. Policy implications highlight the importance of addressing economic factors and improving access infrastructure to manage motorized vehicle reliance and foster sustainable urban mobility in Hanoi.展开更多
