Protein isolates of mice that received rAAV–mFKN (1108 ± 264.7) and rAAV–sFKN (1207 ± 301.8) then subjected to sustained 4 weeks of diabetes (4-wk D) showed FKN levels comparable to the reference group, wild-type (WT) mice (823.7 ± 1073). This evidence concerns the gene CX3CL1 and diabetes mellitus.
