Effect of heavy metal scavenger metallothionein (MT) on low temperature-induced cardiomyocyte contractile dysfunction. FVB and MT mice were kept at room temperature or 4°C for 3 months prior to the mechanical assessment. A: Resting cell length; B: Peak shortening (PS, normalized to cell length); C: Maximal velocity of shortening (+ dL/dt); D: Maximal of relengthening (− dL/dt); E: Time-to-PS (TPS) and F: Time-to-90% relengthening (TR90). Mean ± SEM, n = 123 –126 cells from 4 mice per group, * p < 0.05, NT: normal temperature.
