Passage | Protein Tyrosine Kinase/RTK |
Background | PP2 is a reversible, ATP-competitive Src family inhibitor. |
Biological Activity | PP2 是可逆, ATP 竞争性的 Src 家族抑制剂, 抑制 Lck 和 Fyn的IC50 分别为 4 和 5 nM[1]。 |
IC50 | IC50: 4nM (Lck) , 5nM (Fyn) [1] |
In Vitro | 在10μM时,PP2对细胞增殖的影响不显着,表明在这种低浓度下,PP2对吉西他滨细胞毒性的作用不仅仅反映了直接的抗增殖作用,而是反映了吉西他滨诱导的细胞毒性的增强作用。高于20μM,生长受到越来越多的抑制,这一发现与其他人类癌症细胞系的报道一致。虽然在我们的研究中使用10μMPP2,但据报道PP2浓度较高时会抑制其他细胞内激酶[2]。 PP2是最广泛使用的市售Src家族激酶抑制剂。 PP2抑制Src家族激酶活性,体外IC50为~5 nM,通常需要浓度达到10μM才能在细胞培养中实现完整的Src家族激酶抑制[3]。 |
In Vivo | PP2治疗组肿瘤生长抑制率为25%,吉西他滨治疗组为5%(P> 0.05)。当联合给药时,PP2和吉西他滨产生98%的肿瘤生长抑制率(P <0.05)。 100%的对照组和吉西他滨治疗组均发生肝转移; 88%的PP2治疗组发生肝转移。在用PP2和吉西他滨联合治疗的组中没有可检测到的转移(P <0.05)[2]。 |
Cell Experiment | 通过MTT测定确定细胞生长并通过细胞计数确认。已显示MTT测定的结果与胰腺癌细胞系中的[3H]胸苷掺入良好相关。将对数生长的细胞以5×10 3个细胞/孔接种在96孔板中,使其粘附24小时,并在PP2和吉西他滨存在或不存在下培养。 96小时后测定细胞增殖。使用Vmax微孔板分光光度计在570nm波长下读取平板,校正至650nm并标准化为对照。每个独立实验进行三次,对每个测试条件进行10次测定。根据这些结果计算出吉西他滨的IC50。在相同的时间点,将细胞用胰蛋白酶消化以形成单细胞悬浮液。使用Neubauer血细胞计数器计算通过台盼蓝排除法测定的完整细胞,计算每mL的细胞数并与对照组比较以确认MTT结果[2]。 |
Animal Experiment | 小鼠[2]雄性无胸腺nu / nu小鼠(年龄,5周; 体重,20-22克; 无特定病原体)用ip氯胺酮(200 mg / kg)和甲苯噻嗪(10 mg / kg)麻醉并接种106吉西他滨耐药的PANC1GemRes细胞在20μLPBS中通过外科原位植入胰腺。接种后,将小鼠随机分成三个治疗组:(a)治疗组1(n = 8)通过ip注射每周三次在1%DMSO中接受2mg / kg PP2;(b)治疗组2(n = 8)在第1组接受的相同体积的1%DMSO载体中接受吉西他滨(100mg / kg),每周三次;(c)治疗组3(n = 8)在与第1组和第2组相同体积的DMSO中接受2mg / kg PP2和100mg / kg吉西他滨,每周三次。对照组每周三次接受与其他组相同体积的1%DMSO载体。植入后1天开始治疗,植入后4周进行尸体剖检。鉴定原发性肿瘤,称重并标准化为总体重。使用以下公式计算肿瘤生长抑制率:肿瘤生长抑制率(%)=(1-MT / MC)×100,其中MT和MC分别是治疗组和对照组的平均归一化肿瘤质量。计数肝转移并在组织学上确认。 |
