Background & Hypothesis Relationship b/w ♥ & hormones Ca++ Homeostasis proteins (NCX1, SERCA2a, PLB, CSQ,
CRT…) Contract = Ca++ → cytosol Relax = Ca++ → SR & ECM
Acute Stress: exercise
Oxidative stress : Doxorubicin ± Dexrazoxane
Hyp: Expression of Ca++ regulating proteins is
. Hormone-dep and is correlated to ♥ fct
