pigmentation
• upon induction of Ppargc1a expression in melanocytes, mice exhibit a noticeably darkened coat color relative to the yellow coat color of Ay/a Tg(Tyr-rtTA)37Lc/0 mice; however, the coat color does not become completely black
• upon induction of Ppargc1a expression in melanocytes, mice exhibit significantly increased presence of melanin in hair follicles relative to Ay/a Tg(Tyr-rtTA)37Lc/0 mice

growth/size/body
• following doxycycline treatment, adult mice exhibit eccentric hypertrophy unlike in wild-type mice

cardiovascular system
• following doxycycline treatment of neonates, myofibril mitochondria density is increased 3.5-fold compared with wild-type myofibrils due to increased biogenesis
• doxycycline-treated adult mice exhibit an increased in mitochondrial biogenesis in myofibrils compared with wild-type mice but not to the extent observed in doxycycline treated neonates
• however, removal of doxycycline restores normal mitochondria
• following doxycycline treatment, adult mice exhibit eccentric hypertrophy unlike in wild-type mice
• 2 week after doxycycline treatment, adult mice exhibit increased end-diastolic and end-systolic left ventricle diameter and a mild increase in left ventricular wall thickness compared with wild-type mice
• following doxycycline treatment of adult mice
• following doxycycline treatment of adult mice
• following doxycycline treatment, adult mice exhibit decreased fractional shortening compared with wild-type mice
• however, removal of doxycycline restores cardiac muscle contractility
• following doxycycline treatment of adult mice
• following removal of doxycycline
• following induction of expression with doxycycline, adult mice exhibit reversible cardiomyopathy unlike wild-type mice
• however, no increase in cardiac cell apoptosis is observed

cellular
• following doxycycline treatment, adult mice exhibit an increase in mitochondrial number along with mitochondrial ultrastructural abnormalities unlike in wild-type mice
