Doxorubicin and NRG-1/erbB4-Deficiency Affect Gene Expression Profile: Involving Protein Homeostasis in Mouse

Figure 1

Doxorubicin exacerbates ventricular dilation in adult erbB4-KO hearts. Hematoxilin-eosin stained longitudinal and transverse ventricular sections from doxorubicin-treated (a) 1-month young adult erbB4F/F:MLC2v+/+ (WTD), and erbB4F/F:MLC2v-Cre+/− (erbB4-KOD) mice and (b) 3-months adult WTD and erbB4-KOD mice display exacerbated ventricular dilation. Dilation of both RV and LV is noted in the doxorubicin-treated at the age of 1 month erbB4-KO hearts. Aggravated dilation was monitored at the age of 3 months. Scale bar: 1 mm.
