Caspase-9, caspase-3 và caspase-7 có vai trò khác nhau trong quá trình tự chết tế bào
Tóm tắt
Apoptosis là một hình thức chết tế bào có lập trình được điều hòa bởi gia đình protein Bcl-2 và gia đình protein caspase. Đường truyền caspase chịu trách nhiệm thực hiện cái chết tế bào sau khi giải phóng cytochrome
Trong nghiên cứu này, chúng tôi chứng minh một số chức năng độc đáo cho mỗi caspase trong quá trình chết tế bào. Việc ức chế đặc hiệu caspase-9 cho phép giải phóng cytochrome
Tổng hợp dữ liệu này cho thấy caspase-9 là cần thiết cho sự thay đổi hình thái ti thể và sản xuất ROS qua việc cắt và kích hoạt Bid thành tBid. Sau khi được kích hoạt bởi caspase-9, caspase-3 ức chế sản xuất ROS và là cần thiết cho việc thực hiện apoptosis một cách hiệu quả, trong khi caspase-7 hiệu ứng là cần thiết cho việc tách biệt tế bào apoptotic.
