ATP2A3 and Sepsis: Regarding relaxation, sepsis reduced the ATPase Sarcoplasmic/Endoplasmic Reticulum Ca2+ Transporting 3 (SERCA3) expression in both groups and decreased solute carrier family 8-member 1 (SLC8A1) transcript expression, the Na+/Ca2+ exchanger, in control female and the ATPase plasma membrane Ca2+ transporting protein (ATB2B2) expression in OVR female (Fig. 4 and Table 3).
