Tăng cường MnSOD ty thể do EAE gây ra liên quan đến sự gia tăng protein SGK1 và Tom20 trong vỏ thận chuột
Tóm tắt
Sự chứng minh trước đây của chúng tôi rằng viêm tủy tự miễn dịch (EAE) nặng làm tăng độ phong phú protein MnSOD trong vỏ thận chuột đã dẫn đến nghiên cứu này nhằm làm rõ cơ chế tiềm ẩn với các tế bào HEK293 được xử lý bằng monensin như một mô hình. EAE nặng tăng cường độ phong phú protein ty thể của kinase SGK1 và Tom20, một tiểu đơn vị quan trọng của translocase ty thể trong vỏ thận. Trong các tế bào HEK293, catalase ức chế sự gia tăng protein SGK1 và Tom20 ty thể do monensin gây ra. Hơn nữa, GSK650394, một chất ức chế cụ thể của SGK1 làm giảm sự gia tăng độ phong phú protein ty thể của Tom20 và MnSOD do monensin gây ra. Cuối cùng, RNAi của Tom20 làm giảm tác động của monensin lên MnSOD. MnSOD và Tom20 liên kết vật lý với nhau. Tóm lại, trong các tế bào HEK293, các loại oxy phản ứng ty thể gia tăng độ phong phú protein của SGK1 ty thể, dẫn đến sự tăng lên của Tom20 ty thể, kết quả là nhập protein MnSOD vào ty thể. Đây có thể là một cơ chế mà qua đó EAE nặng kích thích tăng cường MnSOD ty thể trong vỏ thận.
