is a metastatic suppressor inconsistently reported to have multiple roles as both a promoter and inhibitor of cancer metastasis. Nevertheless, the specific mechanism behind these results is still unclear. We observed that A549 cells with stable transfer of into the nucleus (A549-nNm23-H1) exhibited significantly increased migration and invasion activity compared to vector control cells, which was further enhanced by over-expressing CYP24A1 ( < 0.001). demonstrated the ability to safely attach to and amplify the transcription activation of JUN, consequently leading to the up-regulation of . Analysis of clinical data showed a positive relationship between nuclear levels and expression. Furthermore, they were positively associated with postoperative distant metastasis and negatively correlated with prognosis in those with early stage lung adenocarcinoma. In conclusion, the data presented provides a new understanding of the probable pathways by which nuclear facilitates tumor metastasis, establishing the groundwork for future prediction and treatment of tumor metastasis.
是一种转移抑制因子,但关于其在癌症转移中兼具促进和抑制多种作用的报道并不一致。然而,这些结果背后的具体机制仍不清楚。我们观察到,稳定转染至细胞核的A549细胞(A549-nNm23-H1)与载体对照细胞相比,迁移和侵袭活性显著增加,而过表达CYP24A1进一步增强了这种活性(P < 0.001)。显示出能够安全地附着并增强JUN的转录激活,从而导致 的上调。临床数据分析显示细胞核 水平与 表达之间呈正相关。此外,它们与术后远处转移呈正相关,与早期肺腺癌患者的预后呈负相关。总之,所呈现的数据为细胞核 促进肿瘤转移的可能途径提供了新的认识,为未来肿瘤转移的预测和治疗奠定了基础。
