透明细胞肾细胞癌(ccRCC)是最常见的肾癌,且诊断经常为晚期。即使经过适当的治疗,也容易发生不可预测的转移。抗血管生成治疗是转移性ccRCC最有效的治疗方法。因此,探索抑制血管生成和转移的新方法有可能为ccRCC带来更好的治疗方案。

在所有类型的癌症中,肾癌样本再Oncomine数据库中ApoC1的上调幅度最大,且ApoC1的表达增加伴随着ccRCC的进展。在ccRCC患者中,高水平的ApoC1蛋白与较差的生存时间密切相关。更多的是,ApoC1在高侵袭性ccRCC细胞中的表达量比低侵袭性ccRCC细胞高。此外,ApoC1能够通过EMT途径促进ccRCC细胞的转移,ApoC1的失却能够减弱这些作用。ApoC1作为一种新型的促转移因子,能促进STAT3的激活,增强ccRCC细胞的转移。同时,外泌体中的ApoC1能够从ccRCC细胞转移到血管内皮细胞,通过激活STAT3促进ccRCC细胞的转移。

ApoC1促进ccRCC的转移

最后,研究人员指出,由ApoC1驱动的ccRCC细胞的转移潜能被DPP-4抑制剂所抑制。他们的研究不仅鉴定了在ccRCC转移中新的ApoC1-STAT3通路,也为未来预测和治疗转移性ccRCC的新策略的探索提供了方向。
