评估细胞死亡,增殖和细胞亡.
在体外和体内操纵PUMA表达 (过度表达和淘汰) .
在野生型和PUMA-knockdown裸体小鼠的U373-MG异种移植模型中评估阿法替尼的疗效.

主要成果:

阿法替尼抑制了质瘤细胞的生长和增殖,同时诱导了亡.
阿法替尼治疗可提高普马的表达.
马的过度表达增强了阿法提尼布诱导的亡,而马的敲击减弱了这种效应.

mTOR Signaling and Cancer Progression

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
