| Outline of Final Research Achievements |
We examined effects of IL-6 or La3+ on MHC I, HSP70, and IL-6 mRNA expression level using real-time PCR method in C2C12 skeletal muscle cells. First, we examined the effect of IL-6 on MHC I, HSP70, and IL-6 mRNA expression levels. These mRNA levels were significantly increased by the incubation with IL-6. Second, we examined the effect of La3+ on MHC I, HSP70, and IL-6 mRNA expression levels. These mRNA levels were significantly increased by the incubation with La3+. The effects of La3+ on these mRNA levels are considered as a result of calcineurin activation, because it was well known that La3+ stimulate the activity of calcineurin. La3+-induced upregulation of these mRNA levels were significantly attenuated by the application of calcineurin inhibitor, cyclosporin A. These results indicate that IL-6- and La3+/calcineurin-mediated mechanisms contribute to the upregulation of MHC I mRNA levels in C2C12 cells.
