生物活性
BEZ235 (NVP-BEZ235, Dactolisib) 是一种咪唑并喹啉衍生物,能ATP竞争性的抑制PI3K和mTOR,对p110α/γ/δ/β和mTOR(p70S6K)均有抑制作用,IC50分别为4 nM/5 nM/7 nM/75 nM/6 nM,对ATR也有抑制作用,IC50为21 nM;但对Akt和PDK1抑制作用微弱。BEZ235是ATP竞争性的PI3K和mTOR抑制剂 ,作用于p110α, p110γ, p110δ 和 p110β的IC50分别为4, 5, 7和75 nM。BEZ235 (NVP-BEZ235)也是mTORC1/2 催化剂的抑制剂。BEZ235明显降低mTOR激活激酶p70S6K的磷酸化水平。

Resembling the WB results from the BZA treatment, the inhibitors AG490, NVP-BEZ23 and AZD6244 imitated BZA function, down-regulating the pivotal protein of the JAK/STAT3, PI3K/AKT/mTOR and Ras/Raf/MEK/ERK signal pathways |

In addition, using the respective AG490 (50 μmol/l), NVP-BEZ235 (96 nmol/l) and AZD6244 (32 μmol/l) inhibitors for 24 h to mimic the BZA effect in colon cancer cells, we observed that the Bad/Bcl-2 ratio was significantly up-regulated and that Ki-67 mRNA expression was substantially down-regulated in this treatment group compared with the control group |

Following BEZ235 treatment with or without ABT263, the expression of MCL-1 was suppressed while PUMA was increased; correspondingly, the expressions of p-AKT and p-4EBP1 were significantly suppressed. |

实验结果 |
BIM and BAK were obviously released to trigger apoptosis once MCL-1 was suppressed by adding BEZ235 in the presence of ABT-263. Of note, although PUMA was upregulated by BEZ235, less PUMA was bound to MCL-1 than control group due to inhibition of MCL-1. |

We found that, besides MCL-1, the expression of PUMA but not other members was significantly increased following treatment of BEZ235 with or without ABT263 in MDA-MB-231, MDA-MB-157, and MDA-MB-468 cells. |

方法 |
Cell viability assay Cells were seeded at a density of 2000 cells per well in a 96-well plate and incubated overnight in complete medium. Cells were treated with either trastuzumab, BEZ235, Everolimus, AZD6244 alone, or trastuzumab combined with BEZ235 or Everolimus or AZD6244. After 72 h of incubation, cell viability was determined using the MTS tetrazolium substrate (CellTiter 96 Aqueous One Solution Cell Proliferation Assay, Promega, Madison, WI, USA) following the manufacturer’s instructions. The absorbance was measured at 490 nm using a spectrophotometer. All experiments were repeated three times with at least triplicate readings for each concentration.
