This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. Primary support for the subproject and the subproject's principal investigator may have been provided by other sources, including other NIH sources. The Total Cost listed for the subproject likely represents the estimated amount of Center infrastructure utilized by the subproject, not direct funding provided by the NCRR grant to the subproject or subproject staff. Mitochondrial production of reactive oxygen species and oxidation of cardiolipin are key events in initiating apoptosis. We reported that group VIA Ca(2+)-independent phospholipase A(2) (iPLA(2)beta) localizes in and protects beta-cell mitochondria from oxidative damage during staurosporine-induced apoptosis.

这个子项目是许多利用资源的研究子项目之一 由NIH/NCRR资助的中心拨款提供。子项目的主要支持 而子项目的主要调查员可能是由其他来源提供的， 包括其它NIH来源。 列出的子项目总成本可能 代表子项目使用的中心基础设施的估计数量， 而不是由NCRR赠款提供给子项目或子项目工作人员的直接资金。 线粒体产生活性氧和氧化心磷脂是启动细胞凋亡的关键事件。我们报道了VIA组Ca（2+）非依赖性磷脂酶A（2）（iPLA（2）beta）定位于β细胞线粒体中，并在星形孢菌素诱导的细胞凋亡期间保护β细胞线粒体免受氧化损伤。
