Abstract

Cardiac fibrosis and remodeling are critical contributors to heart failure, particularly in the context of diabetes, where hyperglycemia (HG) exacerbates pathological fibroblast activity. Despite the known cardiovascular benefits of canagliflozin (CANA), its specific effects on human cardiac fibroblasts (HCFs) under HG conditions remain unexplored. We investigated whether CANA could mitigate HG-induced detrimental responses in HCFs. Dose-response assays revealed that 100 nM CANA significantly reduced HG-induced proliferation and migration of HCFs. Furthermore, CANA attenuated mitochondrial reactive oxygen species (ROS) production, a key driver of myofibroblast differentiation, and suppressed HG-induced expression of SMAD2, a critical activator of cardiac fibroblasts. Additionally, HG disrupted calcium (Ca2+) homeostasis, which was ameliorated by CANA treatment. These findings collectively demonstrate that CANA exerts protective effects on HCFs by improving mitochondrial function, restoring Ca2+ handling, and reducing fibroblast proliferation, migration, and activation under HG conditions.

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.
