j********r 发帖数: 156 | 4 Generally, the kinases for T308 and S473 of Akt are PDK1 and mTOR complex 2
respectively. PI3K causes the production of PIP3 on the membrane, which then
binds to both Akt and PDK1 (which is assumed to be constitutively active).
So far there seems no direct evidence as to how mTORC2 is regulated. However
, inhibition of PI3K in most cases will lead to the suppression of
phosphorylation at S473.
Just curious, what is the evidence for PI3K-independent S473 phosphorylation

对于恶性肿瘤患者而言,最可怕的莫过于肿瘤出现转移扩散,因为这意味着肿瘤病变已经发展到晚期,也是肿瘤治疗失败的重要原因之一。今天在第七届中国肿瘤学术大会上披露,国际权威学术杂志《抗癌研究》(Anticancer Research)刊发了英国卡迪夫大学关于中药抑制肿瘤转移的研究报告,在国际上引起广泛关注。
英国卡迪夫大学医学院研究证实,我国抗肿瘤创新中药养正消积胶囊可有效抑制肿瘤细胞侵袭转移。研究人员指出,在肿瘤细胞的侵袭转移过程中,磷酸肌醇 3-激酶/蛋白激酶 B(PI3K/AKT) 信号通路的过度激活起到了关键作用,养正消积胶囊可以显著干预 PI3K/AKT 通路,从而对乳腺癌、肠癌、前列腺癌、肺癌、胃癌和骨肉瘤等肿瘤细胞的黏附和迁移起到明显抑制作用,有效控制肿瘤的病变发展。
有关专家介绍,恶性肿瘤细胞非常容易从原发病灶上脱落,每克肿瘤组织每天可向血液中释放 300―400万个肿瘤细胞,脱落的肿瘤细胞随血液或淋巴流布全身,一旦条件成熟就会迅速生长,形成转移性病灶。控制肿瘤细胞的侵袭扩散是避免肿瘤恶... 阅读全帖 |

一年一度的诺贝尔奖是学术界最大的盛事之一。随着2017年诺贝尔奖公布的时间进入一
个月倒计时,陆续有机构开始“押宝”谁会是今年的得主。
当地时间9月20日,科睿唯安(原汤森路透知识产权与科技事业部)公布了最新的“引
文桂冠奖”,预测了22位可能在今年或未来,获得生理学或医学、物理、化学、经济学
诺贝尔奖的学者。
其中,华裔科学家、美国匹兹堡大学医学院病理学特聘教授张远(Yuan Chang)和其丈
夫、同为匹兹堡大学教授的帕特里克·摩尔(Patrick S. Moore)一同上榜生理学或医
学领域的“引文桂冠奖”。上榜原因是这对“夫妻档”科学家一起发现了卡波济氏肉瘤
相关疱疹病毒(KSHV),又名人类疱疹病毒(HHV8)。
张远1959年出生于中国台湾。除了KSHV/ HHV8病毒,她和摩尔还与他人一同发现了引起
梅克尔细胞癌的梅克尔多元癌细胞病毒(MCV)。2012年,张远当选美国科学院院士。

t***s 发帖数: 163 | 45 其实是3个问题:
1. GSK的荧光底物筛选模型 是否是 假阳性
这个几乎是铁板钉钉的事实,4个实验室,5个不同模型全部证明
荧光底物结合SIRT1是假阳性
2. SIRT1能否作为糖尿病(衰老)的靶点
直接从酵母,果蝇跳跃到哺乳动物或人,现在证据不足
一篇SIRT1 gene KO, 几篇transgenic mice的结果
我个人觉得not convincing
3. resveratral及类似物是否直接target SIRT1
resveratral研究很多是hype,流行病学的研究结果
无法在临床试验中重复。
reveratrol的靶点太多(IKK,NFkB,AP1,COX,PI3K)
SIRT1只是最近才提上来的热点
考虑到荧光底物模型的不可靠性,我认为SIRT1是否
直接被resvatroal激活还要重新考虑
其他的类似物也要重新认识
Bottom line
