3 μM ABT737 inhibited growth and viability of TF-1 cells and potentiated proapoptotic effects of 1 μM BIO after 72 hours treatment. TF-1 cells treated with both drugs exhibited more apoptotic cells compared to those treated with each single drug. ABT737 abrogated the protection from BIO-induced apoptosis provided by MS5 coculture.

Breast cancer cell lines were incubate d for 48 hours with 10μM GSIXII or DMSO (Ct) in combination or not with ABT-737, 1 μM. Then apoptosis was evaluated with Apo2.7 or Annexin-V staining and flow-cytometry analysis. Represented data are the means of positive cells ± SEM, from three independent experiments.(A) Suboptimal concentrations of GSIXII (5 μM) and 1 μM ABT-737 were used alone or in combination in MFU assay in MCF7 and BT549 cell lines. Results were obtained from three independent experiments and compared with mock-treated condition. (B) The 20 μM SAHM1 was used alone or in combination in MFU assay in MCF7 and BT549 cell lines. Results were obtained from three independent experiments and compared with the mock-treated condition.

ABT-737 shows low activity to Bcl-B and no effects to Mcl-1 and BFL-1. ABT-737 is sensitive to HL60, KG1 and NB4 cells with IC50 of 50 nM, 80 nM and 80 nM, respectively. ABT-737 induces apoptosis in HL60 cells, which due to decreased Bcl-2/Bax heterodimerization and has no effect on cell cycle distribution. ABT-737 also induces cytochrome c release from purified mitochondria and promotes conformational changes in Bax that are associated with apoptosis.  Resistant cells (Hela and MCF-7) can be sensitized to ABT-737 by approaches that down-regulate, destabilize, or inactivate Mcl-1. ABT-737 also causes Bax/BAK-dependent cytochrome c release only when Mcl-1 has been neutralized.  ABT-737 displaces Bim from Bcl2's BH3-binding pocket, allowing Bim to activate Bax, induce mitochondrial permeabilization, and rapidly commit the primary chronic lymphocytic leukemia (CLL) cells to death.  Knockdown of Mcl-1 with siRNA sensitizes two resistant SCLC cell lines H196 and DMS114 to ABT-737 by enhancing the induction of apoptosis. Likewise, up-regulation of Noxa sensitizes H196 cells to ABT-737. ABT-737 inhibits proliferation and induces apoptosis in many SCLC cell lines including NCI-H889, NCI-H1963, NCI-H1417, NCI-H146 and etc. Bcl-2 and Noxa may contribute mechanistically to the cellular response to ABT-737 in NCI-H146 cells.  A recent study shows that ABT-737 significantly induces apoptosis in HTLV-1 infected T-cell lines as well as in fresh ATLL cells. 
|体内試験||In aggressive leukemia model, ABT-737 suppresses the leukemia burden by 53% at the 30 mg/kg, with significantly extended survival of mice. ABT-737 does not induce significantly abnormalities in blood cell counts or serum chemistries.  ABT-737 prolongs the survival of recipient mice transplanted with Bcl-2-transduced tumors.  ABT-737 shows great antitumor activity in an ATLL mouse model at a dose of 100 mg/kg. |
Fluorescence polarization assays:Binding affinity of GST-Bcl-2 family proteins to the FITC-conjugated BH3 domain of Bim (FITC-Ahx-DMRPEIWIAQELRRIGDEFNAYYAR) is determined. Briefly, 100 nM of GST-Bcl-2 family fusion proteins are incubated with serial dilutions of ABT-737 in PBS for 2 min. Then, 20 nM of FITC-Bim BH3 peptide (FITC-Ahx-DMRPEIWIAQELRRIGDEFNAYYAR) is added. Fluorescence polarization is measured using an Analyst TM AD Assay Detection System after 10 min using the 96-well black plate. Then IC50 are determined.
