GADD45A suppression contributes to cardiac remodeling by promoting inflammation, fibrosis and hypertrophy
This study, primarily using a mouse knockout model and human heart cell lines, found that suppressing the GADD45A gene leads to severe cardiac problems, including inflammation, fibrosis, and an enlarged heart. Overexpressing GADD45A in human heart cells, conversely, helped prevent these adverse responses, while human patient data showed a correlation between lower GADD45A levels and increased left ventricular mass and fibrosis. The authors suggest that boosting GADD45A activity could be a therapeutic strategy to slow the progression of heart disease.
