KCTD-12抑制胃间质瘤细胞体外增殖、侵袭的实验研究

目的:研究过表达钾通道四聚化结构域-12蛋白(KCTD-12)对胃间质瘤细胞体外增殖、侵袭的影响。方法:培养胃间质瘤细胞株GIST-T1并随机分为KCTD-12过表达组和NC过表达组,分别转染KCTD-12过表达质粒及阴性对照质粒。转染后24小时,检测细胞中增殖基因、凋亡基因、PI3K及p38MAPK信号通路分子、侵袭基因的表达量。结果:KCTD-12过表达组细胞中Ki-67、SCIN、Bcl-2、pPI3K、p-AKT、p-p38MAPK、CD146、PAR-2、SDF-1、CXCR4的表达量显著低于NC过表达组,Bax、Caspase-3、Caspase-7、Caspase-9、p-FOXO1的表达量显著高于NC过表达组。结论:KCTD-12能够抑制胃间质瘤细胞的体外增殖、侵袭。

KCTD-12 inhibits the in vitro proliferation and invasion of gastrointestinal stromal tumor cells: the experimental study

Objective:To study the effects of potassium channel tetramerization domain-containing 12 (KCTD-12) overexpression on in vitro proliferation and invasion of gastrointestinal stromal tumor cells.Methods:Gastrointestinal stromal tumor cell lines were cultured and randomly divided into KCTD-12 overexpression group and NC overexpression group that were transfected with KCTD-12 overexpression plasmid and negative control plasmid respectively. 24 h after transfection, the expression of proliferation genes, apoptosis genes, PI3K and p38MAPK signaling pathway molecules as well as invasion genes in cells were detected. Results: Ki-67, SCIN, Bcl-2, p-PI3K, p-AKT, p-p38MAPK, CD146, PAR-2, SDF-1 and CXCR4 expression in KCTD-12 overexpression group were significantly lower than those in NC overexpression group while Bax, Caspase-3, Caspase-7, Caspase-9 and p-FOXO1 expression were significantly higher than those in NC overexpression group.Conclusion:KCTD-12 can inhibit the in vitro proliferation and invasion of gastrointestinal stromal tumor cells.
