Substitution of SERCA2 Cys aggravates cardiac fibrosis by promoting the transformation of cardiac fibroblasts to cardiac myofibroblasts.

Sarcoplasmic/endoplasmic reticulum Ca ATPase 2 (SERCA2) is vital to maintain intracellular calcium homeostasis, and its redox Cys (C674) is the key to regulating activity. Our goal was to investigate whether the redox state of SERCA2 C674 is critical for cardiac fibrosis and the mechanisms involved. Heterozygous SERCA2 C674S knock-in (SKI) mice, in which half of C674 was substituted by serine, were used to mimic the partial loss of the reactive C674 thiol in pathological conditions.
