Figure 3. Unanswered questions regarding the actions of HDACs in the pathogenesis of heart failure.

Figure 3

Strong evidence implicates class I HDACs in the pathogenesis of heart failure. However, data defining the roles of specific HDAC isoforms is just beginning to emerge. Beyond that, little is known regarding the protein target(s) which is/are reversibly acetylated in these processes. Whether those proteins govern transcriptional, signaling, or other events, is similarly unknown.
