“…Accordingly, the cardiomyocyte hypertrophic response is characterized by increases in cardiomyocyte size, RNA concentration, and protein synthesis as well as expression of fetal genes including atrial natriuretic factor (ANF) [ 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 ] due to the activation of several transcription factors [ 14 , 15 ]. Furthermore, a transient activation of the c-Fos and c-Jun complex (AP-1) also occurs in the early response to hypertrophic stimuli [ 14 , 16 ]. In fact, cumulative evidence has determined that both AP-1 complex and ANF induce the activation of several hypertrophic genes [ 14 , 17 , 18 , 19 ].…”
