MYOZ1 and sarcopenia: Among these changed genes, calsarcin-2 was significantly increased, and we also confirmed the increased level of calsarcin-2 mRNA through real-time PCR (p < 0.001) (Figure 2B) and protein expressions by Western blots (p < 0.001) (Figure 2C) in the gastrocnemius muscle of the sarcopenia mouse model, as compared with the control group.
