| Research Abstract |
We have developed 5 optic probes to evaluate liver stresses targeting intracellular molecular markers and pH. 1. a redox-sensitive mutant GFP (roGFP) probe for oxidative stress, 2. an optic probe for ER stress, 3. an optic probe for cell death (necroptosis), 4. an optic probe for cell viability (Akt phosphorylation), 5. an optic probe for cellular pH.
We have checked efficacy of these optic probes in liver cells. As for a roGFP probe and a pH-sensitive probe, we have checked usefulness of these probes in vivo, by using mice models.
