ITGB1 and cardiac hypertrophy: Myocardial hypertrophy was associated with the downregulation of SRC proto-oncogene, non-receptor tyrosine kinase (SRC), mitogen-activated protein kinase 14 (MAPK14), emerin (EMD), and integrin subunit beta 1 (ITGB1).<h4>Conclusions</h4>An 18-month HFD successfully established a translational M. fascicularis model replicating key metabolic disorders (MASH, diabetes, cardiac hypertrophy).
