诱导多能干细胞(iPSC)从分化细胞的衍生所涉及的分子机制知之甚少。在这里,我们报告,半胱天冬酶3和8,两个蛋白酶与细胞凋亡相关的细胞死亡,在诱导iPSCs从人成纤维细胞中发挥关键作用。半胱天冬酶3和8的活化在iPSC诱导转录因子转导后不久发生。Oct-4是一种关键的iPSC转录因子,负责激活。抑制人成纤维细胞中的半胱天冬酶3或8分别部分或完全阻止iPSC的诱导。此外,视网膜母细胞瘤易感性(Rb)蛋白似乎是作用于caspase下游的因子之一。我们认为,半胱天冬酶是iPSC诱导中核重编程的关键促进因素。
The molecular mechanisms involved in the derivation of induced pluripotent stem cells (iPSCs) from differentiated cells are poorly understood. Here we report that caspases 3 and 8, two proteases associated with apoptotic cell death, play critical roles in induction of iPSCs from human fibroblasts. Activation of caspases 3 and 8 occurs soon after transduction of iPSC-inducing transcription factors. Oct-4, a key iPSC transcription factor, is responsible for the activation. Inhibition of caspase 3 or 8 in human fibroblast cells partially or completely prevents the induction of iPSCs, respectively. Furthermore, retinoblastoma susceptibility (Rb) protein appears to be one of the factors that act downstream of the caspases. We propose that caspases are key facilitators of nuclear reprogramming in iPSC induction.
