Research Interest
Dr. Sekine has been working on analyzing the moclecular mechanisms underlying cellular responses to a variety of stresses including oxidative stress, endoplasmic stress and metabolic stress. Using biochemical and cell genetic approaches, the Sekine lab is currently focusing on acetyl-CoA fluctuation-dependent functional changes of organelles (including nucleoli, mitochondria and lysosomes) and activation of organelle-associated stress signaling pathways. A long-term goal is to understand the sensing mechanisms of metabolite fluctuations in mammalian cells and reveal their relevance to human aging and age-associated diseases.
