胆囊癌(GBC)是胆道系统最常见的恶性肿瘤。血管生成在恶性肿瘤的发生和进展中发挥着关键作用。 miR-143-3p 在多种癌症中充当肿瘤抑制因子。然而,他们在 GBC 中的角色尚不明确。在这里,我们发现,与非肿瘤邻近组织(NAT)对应物相比,人类 GBC 组织中 miR-143-3p 的表达水平降低,并且与总体生存密切相关。我们发现 miR-143-3p 是体内和体外肿瘤生长和血管生成的新型抑制剂。我们的抗体阵列、ELISA 和 PLGF 救援分析表明 PLGF 在 miR-143-3p 的抗血管生成作用中发挥重要作用。此外,我们使用 miRNA 靶标预测软件和双荧光素酶测定来确认整合素 α6 (ITGA6) 是 miR-143-3p 的直接靶标。我们的 ELISA 和蛋白质印迹分析证实,PLGF 的表达通过 ITGA6/PI3K/AKT 途径降低。总之,miR-143-3p通过ITGA6/PI3K/AKT/PLGF通路抑制GBC的肿瘤血管生成和生长,可能是GBC的新分子治疗靶点。
Gallbladder cancer (GBC) is the most common malignant tumour of the biliary track system. Angiogenesis plays a pivotal role in the development and progression of malignant tumours. miR-143-3p acts as a tumour suppressor in various cancers. Their role in GBC is however less well defined. Here we show that the expression levels of miR-143-3p were decreased in human GBC tissues compared with the non-tumour adjacent tissue (NAT) counterparts and were closely associated with overall survival. We discovered that miR-143-3p was a novel inhibitor of tumour growth and angiogenesis in vivo and in vitro. Our antibody array, ELISA and PLGF rescue analyses indicated that PLGF played an essential role in the antiangiogenic effect of miR-143-3p. Furthermore, we used miRNA target-prediction software and dual-luciferase assays to confirm that integrin α6 (ITGA6) acted as a direct target of miR-143-3p. Our ELISA and western blot analyses confirmed that the expression of PLGF was decreased via the ITGA6/PI3K/AKT pathway. In conclusion, miR-143-3p suppresses tumour angiogenesis and growth of GBC through the ITGA6/PI3K/AKT/PLGF pathways and may be a novel molecular therapeutic target for GBC.
