The proteins of above genes were also changed significantly in the ARVC group, with the levels of OBSCN and Ank1.5 decreased by 0.65- and 0.55- fold, and levels of N-Cadherin, PPARγ, C/EBPα, and FABP4 increased by 1.73-, 2.48, 3.78, and 3.64- fold, respectively, compared with the controls (Figure 7E-F). Here, FABP4 is linked to Arrhythmogenic right ventricular dysplasia.
