一项来自几位胚胎学科学家的新研究显示,一个特别小的RNA片段可能在恶性儿童眼部肿瘤——视网膜母细胞瘤(reti-noblastoma)的生长过程中起关键作用。该肿瘤与Rb蛋白(或称视网膜母细胞瘤蛋白)的突变有关,Rb功能障碍也与其他肿 A new study from several embryology scientists showed that a particularly small RNA fragment may play a key role in the growth of reti-noblastoma, an ocular tumor in the malignant child. The tumor is associated with a mutation in the Rb protein (or retinoblastoma protein), and Rb dysfunction is also associated with other swollen
