RNA干扰的果蝇Hedgehog途径调控蛋白筛选
就象刺猬一样,以Hedgehog命名的一系列在发育中有重要功能的信号分子还象处在冬眠中的刺猬一样不为人们所认识。Phil Beachy and colleagues在Science上发表的新报道Dlp,CK1等在Hh信号途径中的新功能。 因
内质网蛋白合成的质量控制
细胞进行蛋白质生产的质量控制对细胞的生存是非常重要的,在内质网中分子伴侣calnexin/calreticulin循环保证只有正确折叠的糖蛋白才能到达它们的目的地。而错误折叠的糖蛋白则通过内质网的蛋白质降解途径(ERAD-ER-associated

美国科学家发现上皮细胞自我修复机制
百分之九十以上的传染性病毒都是通过器官黏膜进入人体内的,而黏膜下方的上皮细胞是阻隔这些有害物质的天然屏障,这一层细胞一旦受损,就为病毒和细菌打开了“通路”。日前,美国科学家发现了一种简单的机制,可促使上皮细胞进行自我修复,防止感染。 据最新一期《自

儿童早衰症与基因突变有关
最近美国的科学家在治疗儿童早衰症的研究上也有新突破,他们发现,在人体30亿个碱基对中,一个特殊基因的突变直接导致了这种罕见病症的发生。16号,美国人类基因研究院和儿童早衰症研究基金会的科学家宣布,儿童早衰症并非遗传所至,而是人体内一种名叫LMNA(
