Mitochondrial TCA cycle enzymes translocate to the nucleus upon doxorubicin treatment. A, b Confocal microscopy images of hiPSC-derived cardiomyocytes treated with 1 µM doxorubicin for 6 or 24 h (DRN) or DMSO (control). The cells were stained with anti-isocitrate dehydrogenase (IDH-2) (a) or anti-citrate synthase (CS) (b) and detected with a secondary antibody conjugated with Alexa 594. Cells were stained with CoxIV and Troponin-T (TnT) as markers for mitochondria and cardiomyocytes, respectively. The signals from CoxIV and TnT were detected with secondary antibodies conjugated with Alexa-633 and Alexa-488, respectively. Scale bar: 20 µm. c–f 3-dimensional reconstituted z-stack images of control (c, e) and doxorubicin-treated cells (d, f) stained for MDH-2 (c, d) and IDH-2 (e, f), CoxIV, and TnT.

TnT and Kir2.1 were probed to rule out the contamination of cytoplasmic fractions, and CoxIV was used as a mitochondrial marker in the isolated nuclear lysate. Whole-cell lysates from untreated cells were used as another control. h, i Immunostained images of cardiomyocytes isolated from mice treated with vehicle (h) or doxorubicin (i) for 72 h, cells stained for IDH-2, CoxIV, and TnT.

Background: Kir2.1

Human Inward Rectifier Potassium Channel 2 (KIR2.1), also known as KCNJ2, is a 427 amino acid (aa) integral membrane protein with 98% homology with mouse and rat KIR2.1.   This potassium channel preferentially allows potassium to flow into the cell, which is thought to generate action potential waveform and excitability in neuronal and muscle tissues. Mutations in the KIR2.1 gene are associated with Andersen syndrome, with associated paralysis, cardiac arrhythmias and dysmorphic features. KIR2.1 is widely expressed, notably in heart, placenta, lung, skeletal muscle, kidney and spleen. Expression of KIR2.1 is necessary for development of mature cardiomyocytes from mouse embryonic stem cells.
