IGFBP7 promotes cardiac senescence by stimulating IGF-1R/IRS/AKT-dependent suppression of FOXO3a, and Igfbp7 deficiency or inhibition attenuates cardiac dysfunction in a pressure overload mouse HF model, suggesting that therapeutic targeting of IGFBP7 might be promising for the treatment of HF. This evidence concerns the gene IARS1 and hydrops fetalis.
