LOXL2 and idiopathic dilated cardiomyopathy: Quantification of messenger RNA (mRNA) revealed that LOXL2 expression correlated well with the expression of fibrillar collagen genes (COL1A and COL3A) in ventricular tissues of healthy donor hearts (n=8) and of hearts from patients with idiopathic dilated cardiomyopathy (IDCM, n=10; Fig. 1m,n and Table 1).
