There are two degradation systems in mammalian cells, autophagy/lysosomal pathway and ubiquitin-proteasome pathway. Proteasome is consist of multiple protein subunits and plays important roles in degradation of short-lived cellular proteins. Recent studies reveal that proteasomal degradation system is also involved in signal transduction and regulation of various cellular functions. Dysfunction or dysregulation of proteasomal function may thus be an important pathogenic mechanism in certain neurological disorders. This paper reviews the biological functions of proteasome in signal transduction and its potential roles in neurodegenerative diseases.
塞来昔布(celecoxib)是一种高选择性COX-2抑制剂,在用于镇痛、抗炎方面的疗效与传统的NSA ID s相当,且能降低用药者的胃肠道风险。并通过抑制肿瘤细胞增殖、抑制血管增生及促进肿瘤细胞凋亡而用于消化道肿瘤、乳腺癌、肺癌和肝癌的治疗...

塞来昔布(celecoxib)是一种高选择性COX-2抑制剂,在用于镇痛、抗炎方面的疗效与传统的NSA ID s相当,且能降低用药者的胃肠道风险。并通过抑制肿瘤细胞增殖、抑制血管增生及促进肿瘤细胞凋亡而用于消化道肿瘤、乳腺癌、肺癌和肝癌的治疗。同时能减缓动脉粥样硬化病变,在心血管疾病的治疗方面也具有一定价值。但长期较大剂量应用celecoxib,用药者心血管事件的相对风险增大。
