S100a9 Inhibits Atg9a Transcription and Participates in Suppression of Autophagy in Cardiomyocytes Induced by β1-Adrenoceptor Autoantibodies

The active immunity method was used to establish a β1-AA-induced mouse cardiac dysfunction model, and RT-PCR and western blot were used to detect changes in gene and protein expression in cardiomyocytes.
