As shown in Fig. 6, compared with the UGCG overexpressing group, the group that received a simultaneous administration of UGCG overexpression and B4GalT5 inhibition showed improved myocardial hypertrophy (Fig. 6A–D) and myocardial fibrosis (Fig. 6A, E), along with a decreased myocardial size (Fig. 6F, G) and inhibited expression of ANP and BNP (Fig. 6H–J). This evidence concerns the gene UGCG and cardiac hypertrophy.
