NUP153 and hydrops fetalis: When we compared the plasma levels of SERCA2a, NUP153, RanGAP1, and IPO5, we noted that SERCA2a was significantly lower in the patients with advanced HF and MCS intervention when compared to the patients without MCS (0.501 ± 0.530 ng/mL vs. 1.123 ± 0.661 ng/mL, p = 0.01).
