Figure 1: (a) CPT mRNA expression in different tissues, compared between wild type with CPT1b and knockout mice with CPT1b M−/−. It showed that the expression of CPT1b was significantly reduced in gastric and skeletal muscles (* ). (b) CPT1 activities were reduced in knockout mice compared with wild type, significant at 2, 4, 6, 8, and 10 minutes (* ). for each group.
