    • Methods and compositions for modulating apoptosis in cells and patients are provided. One method comprises selecting a compound which affects the ability of a channel comprised of a member of the BCL-2 family to allow passage of cytochrome c, then administering the compound to the cell or patient. Another method comprises selecting a compound which changes ion conductance properties of the channel, then administering the compound to the cell or patient. Compounds which affect these channel characteristics are also provided. Additionally, methods for identifying apoptosis-modulating compounds using lipid bilayers are provided. One method involves contacting a compound of interest with a lipid bilayer which contains an ion-channel formed by an anti-apoptotic or pro-apoptotic polypeptide of the BCL-2 family and assaying for changes in the ability of the pore to allow passage of cytochrome c. Changes in ion conductance properties of the channel, including ion selectivity, single channel conductance and rectification are also useful characteristics for identifying apoptosis-modulating compounds. A second method identifies compounds which can form ion channels in planar lipid bilayers and determines the ability to allow passage of cytochrome c, the ion selectivity and the pH dependence of such channels, where apoptosis modulating activity is predicted based on comparing these channel forming characteristics with those of BCL-2 family members.

    • Methods and compositions for modulating apoptosis in cells and patients are provided. One method comprises selecting a compound which affects the formation of large channels comprised of multiple molecules of a pro-apoptotic member of the BCL-2 family, then administering the compound to the cell or patient. Another method comprises selecting a compound which affects the formation of a channel that includes at least four molecules of a pro-apoptotic BCL-2 family member polypeptide, then administering the compound to the cell or patient. Compounds which affect these channel characterictics are also provided. Additionally, methods for identifying apoptosis-modulating compounds using lipid membranes are provided. One method involves contacting a compound of interest with a lipid membrane which contains an ion-channel formed by an anti-apoptotic or pro-apoptotic polypeptide of the BCL-2 family and assaying for changes in the size of the pore. Changes in ion conductance properties of the channel, including ion selectivity, the ability to allow the passage of cytochrome c and/or FD10, single channel conductance and rectification are also useful characteristics for identifying apoptosis-modulating compounds.
    • 提供了调节细胞和患者细胞凋亡的方法和组合物。 一种方法包括选择影响由BCL-2家族的促凋亡成员的多个分子构成的大通道的形成的化合物,然后将该化合物给予细胞或患者。 另一种方法包括选择影响形成通道的化合物,该化合物包括至少四个分子的促凋亡BCL-2家族成员多肽,然后将该化合物给予细胞或患者。 还提供影响这些通道特征的化合物。 另外,提供了使用脂质膜鉴定凋亡调节化合物的方法。 一种方法包括使感兴趣的化合物与含有由BCL-2家族的抗凋亡或促凋亡多肽形成的离子通道的脂质膜接触并测定孔的大小变化。 通道的离子传导性质的变化,包括离子选择性,允许细胞色素c和/或FD10通过的能力,单通道电导和整流也是鉴定凋亡调节化合物的有用特征。
