Abstract

Recent studies have shown that intracellular Ca2+ handling is abnormal in the myocardium of patients with end-stage heart failure. Muscles from the failing hearts showed a prolonged Ca2+ transient and a diminished capacity to restore a low resting Ca2+ level during diastole. Accordingly, we examined whether this defect in Ca2+ transport function is due to alterations in sarcoplasmic reticulum gene expression. We determined the messenger RNA (mRNA) levels of sarcoplasmic reticulum Ca2+ transport proteins in failing human hearts from 17 cardiac transplant recipients with a diagnosis of dilated cardiomyopathy, primary pulmonary hypertension, or ischemic heart disease. The expression levels of each mRNA were compared with each other and then correlated with that of atrial natriuretic factor (ANF) mRNA in the failing ventricle. The mRNA levels for the calcium release channel (ryanodine receptor, RYR2), Ca2+ uptake pump (Ca(2+)-ATPase, SERCA2 isoform), and phospholamban differed significantly between heart samples but showed an inverse relation with that of ventricular ANF mRNA. In contrast, calsequestrin mRNA levels remained unchanged in these failing hearts. In addition, beta-myosin and alpha-cardiac actin mRNA levels also showed an inverse relation with ANF mRNA levels. These changes were observed in both right and left ventricles of hearts with congestive heart failure due to dilated cardiomyopathy, primary pulmonary hypertension, or ischemic heart disease. The results are consistent with the hypothesis that abnormal calcium handling in the sarcoplasmic reticulum of failing hearts is due to the altered expression of the genes encoding sarcoplasmic reticulum proteins.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
