HYD-PEP06, an endostatin-modified polypeptide, has been shown to produce effective anti-colorectal carcinoma effects through inhibiting epithelial-mesenchymal transition (EMT). However, whether HYD-PEP06 has similar suppressive effect on hepatocellular carcinoma (HCC) remained unknown. In this study, HYD-PEP06 inhibited metastasis and EMT but not proliferation . Cignal finder pathway reporter array and Western blot analysis revealed that HYD-PEP06 suppressed HCCLM3 cell metastasis and EMT by inhibiting the PI3K/AKT pathway. Moreover, HYD-PEP06 exerted anti-metastasis effects in HepG2 cancer stem-like cells (CSCs) suppressing the WNT/-catenin signaling pathway. Finally, in HCCLM3 tumor-bearing BALB/c / nude mice, HYD-PEP06 substantially suppressed tumor growth, lung metastasis and HCC progress. Our results suggest that HYD-PEP06 inhibits the metastasis and EMT of HCC and CSCs as well, and thus has the potential as an agent for HCC treatment.
HYD-PEP06是一种内皮抑素修饰的多肽,已被证明可通过抑制上皮-间质转化(EMT)产生有效的抗结直肠癌作用。然而,HYD-PEP06对肝细胞癌(HCC)是否具有类似的抑制作用尚不清楚。在本研究中,HYD-PEP06抑制转移和EMT,但不抑制增殖。信号发现者通路报告基因阵列和蛋白质印迹分析表明,HYD-PEP06通过抑制PI3K/AKT通路抑制HCCLM3细胞转移和EMT。此外,HYD-PEP06在肝癌干细胞样细胞(CSCs)中发挥抗转移作用,抑制WNT/β-连环蛋白信号通路。最后,在荷HCCLM3肿瘤的BALB/c裸鼠中,HYD-PEP06显著抑制肿瘤生长、肺转移和HCC进展。我们的结果表明,HYD-PEP06也抑制HCC和CSCs的转移和EMT,因此有潜力作为一种HCC治疗药物。
