内质网(ER)膜蛋白复合体6亚单位(EMC6)是一种新的人类自噬相关分子。在这里,我们利用组织芯片和免疫组织化学方法,报告了胃腺癌患者腺体细胞中EMC6蛋白丢失或减少,与正常胃粘膜相比。在胃癌细胞中过表达EMC6抑制了细胞的生长、迁移和侵袭,并诱导细胞凋亡和细胞周期停滞于S期。进一步的研究表明,EMC6在BGC823人胃癌细胞中的过度表达降低了异种移植瘤模型的致瘤性,表明EMC6具有肿瘤抑制因子的特性。这是首次研究表明EMC6诱导胃癌细胞死亡。EMC6作为肿瘤抑制因子的分子机制还有待进一步研究。
The endoplasmic reticulum (ER) membrane protein complex subunit 6 (EMC6) is a novel human autophagy-related molecule. Here, using tissue microarray and immunohisto-chemistry, we report that EMC6 protein is lost or reduced in glandular cells of patients with gastric adenocarcinoma, compared to normal stomach mucosa. Overexpression of EMC6 in gastric cancer cells inhibited cell growth, migration, invasion, and induced apoptosis and cell cycle arrest at S-phase. Further investigation suggested that EMC6 overex-pression in BGC823 human adenocarcinoma gastric cancer cells reduced tumorigenicity in a xenograft model, demonstrating that EMC6 has the characteristics of a tumor suppressor. This is the first study to show that EMC6 induces cell death in gastric cancer cells. The molecular mechanism of how EMC6 functions as a tumor suppressor needs to be further explored.
