摘要
GRIM一19是维甲酸/干扰素联合应用诱导细胞凋亡相关基因中的一员,是由Angell等筛选出来的一个新的死亡相关基因,定位于人染色体19p13.1,是线粒体复合体I的组成成分。它可以特异性地与STAT3结合,通过下调STAT3的转录激活活性,抑制其靶基因的表达和细胞生长;此外还可以和蛋白GW112、NOD2等相互作用。国内外已经在原发性肾细胞癌等泌尿系统肿瘤、结直肠癌、甲状腺癌中对GRIM一19的表达进行了研究,提出GRIM-19可能成为一个新的肿瘤抑制基因,并可能成为评价疗效的有用的生物标记物和基因治疗的一个潜在的靶点。
Genes associated with retinoid-interferon mortality-19 (GRIM-19) is one of the apoptosis-related genes induced by retinoid-interferon, is screened by Angell and others. It is located at 19p13.1 of human chromosome as a component of mitochondrial complex I. It can specifically bind to STAT3 to inhibit the expression of target gene and cell growth through down-regulating transcription activity of STAT3. In addition,GRIM-19 can interact with GW112 and NOD2. The studies at home and abroad on the expression of GRIM 19 in renal cell carcinoma and other urologic neoplasms, colorectal cancer and thyroid carcinoma have proposed that GRIM-19 may be a novel tumor suppressor, biological marker for evaluating therapeutic effect and potential target for gene treatment.
