NT157 is an IRS-1/2 inhibitor.
Insulin receptor substrates 1 and 2 (IRS1/2) mediate antiapoptotic and mitogenic signaling from insulin receptor (IR), insulin-like growth factor 1 receptor (IGF-IR), and other oncoproteins. IRS1 plays a critical role in cancer cell proliferation, and its expression is increased in many human malignancies.
In vitro: NT157 treatment was fonund to be able to lead to dose-dependent suppression of IRS protein expression, inhibition of IGF1R activation, inhibition of IGF1-induced AKT activation, but increased ERK activation in NT157-treated cells. These effects were associated with decreased proliferation, increased apoptosis of LNCaP cells and increased G2-M arrest in PC3 cells. Moreover, NT157 could significantly affect the cell migratory ability, as demonstrated by a wound-healing assay. In addition, the NT157 treatment was able to induce cell cycle arrest and inhibit IGF system signaling [1].
In vivo: In previous animal study, NT157 was found to suppress androgen-responsive growth, delay CRPC progression of LNCaP xenografts, and suppress PC3 tumor growth alone or in combination with docetaxel. This study reported the first preclinical proof-of-principle data that NT157 suppressed IRS1/2 expression, delayed CRPC progression, and suppressed growth of CRPC tumors in vivo [1].
Clinical trial: Up to now, NT157 is still in the preclinical development stage.

个人大胆一次，把内表面用酒精灯考一下，让表面重新融化。就可以了。各位可以用一块有机版的边缘试试。
可不可以在动物中心（SPF级别）取材后将组织再送到细胞室
而且，紫外在培养基中造成的富氧离子会杀伤细胞。
望采纳^O^
测流式由侧面通过工作台（左右 上下皆可），于是缺点就是在气流层边缘可能出现负压，导致污染。而且其较为封闭，只有手伸入的圆洞，取拿物品较为
