In addition to activation by lipids at the post-translational level,
PKCβ expression in adipose cells fluctuates in response to a high-fat
diet (HFD) intake [27]. We found that feeding mice a HFD for 12 weeks
induced adipose PKCβ expression in an isoform- and tissue-specific
manner. The molecular mechanism(s) underlying transcriptional induction
have yet to be elucidated, but previous studies have implicated
involvement of the PKCβ promoter [28–30]. A cluster of putative binding
