KPT-9274 is a selective and orally bioavailable allosteric inhibitor of PAK4 [1][2][3].
P21 protein (Cdc42/Rac)-activated kinase 4 (PAK4) is a serine/threonine-protein kinase and a member of the PAK family of proteins which are Rac1 and Cdc42 effectors. PAK4 is a mediator of filopodia formation and stabilizes β-catenin transcriptional activity, and is involved in disease progression for several solid tumors [1][2][3].
KPT-9274 is a selective and orally bioavailable PAK4 inhibitor. In MDA-MB-468 cells, KPT-9274 showed anti-tumor activity with IC50 value of 0.12 μM. KPT-9274 reduced PAK4 protein and the key downstream effectors of cell cycle (β-catenin, cyclin D1), cell migration (cofilin), autophagy (AMPK) and apoptosis (Caspase and PARP cleavage) [1]. In RCC cells, KPT-9274 dose-dependently inhibited cell viability [2]. In AML cell lines, KPT-9274 (1 nM-10 μM) inhibited cell proliferation in a dose-and time- dependent way and reduced protein and mRNA expression of PAK4 [3].
In mice inoculated with MDA-MB-231 or MDA-MB-468 cells, KPT-9274 were given orally once daily (5 or 7 days/week) without major toxicity. KPT-9274 induced a maximum TGI of ~55% and ~70% in MDA-MB-231 and MDA-MB-468 mice, respectively [1]. In subcutaneous xenograft mouse models, KPT-9274 inhibited RCC growth [2]. In human AML leukemia xenograft model, KPT-9274 (150 mg/kg) significantly inhibited tumor growth, prevented invasion of MV4-11 cells, and improved overall survival [3].

希望有大神赐教!谢谢!
指导意见:
毕竟阴道上皮是鳞状上皮,而输尿管,膀胱,尿道的上皮是柱状上皮,形态上是不一样的.所以您要是对您的结果出怀疑态度,首先:重新留尿,做一个复检(留尿时注意防止阴道分泌物污染);或者让值班医生分析一下是那种类型的上皮(鳞状还是柱状).所以不要担心这个结果.一般情况下污染的比较多.
病情描述(发病时间、主要症状等):
体检血常规中血小板计数343.血小板比积0.39.
尿检中白细胞计数26.2.上皮细胞计数10.30
心电图下写窦性心律,p-r间期偏短

有没有什么大问题
如题,求助。做肝癌细胞侵袭、迁移实验,用哪种细胞株比较好?
