  1. 바이러스 감염시 미토콘드리아 E3 ubiquitin ligase 인 MARCH5의 새로운 생체 기능

    Mitochondria have a central role in preserving cellular homeostasis. Ubiquitin proteasome system (UPS) on the mitochondria is one of quality control systems that works as a first line barrier against aggregated or misfolded proteins. In this study, I investigated functional role of mitochondrial E3 …

  7. Effects of loigomycin, F0/F1 ATP-synthase inhibitor on mitochondrial morphology and dynamics

    Mitochondrial fission has recently been well-recognized as a factor involved in apoptosis although its role and the underlying mechanism remains unclear. Recently, we monitored the effects of mitochondrial respiratory inhibitors [rotenone, TTFA (2-thenoyltrifluoro-acetone), antimycin A, and …
