(A) Schematic representation of the mouse chromosomal localization of lncRNAs situated in the vicinity of Pitx2, Wnt11 and Wnt8 genes. (B–G) RT-qPCR analyses of Walaa, Walras, Wallrd, Walrad, Walce and Playrr expression levels. We note observe atrial expression of Walaa, Walras and Wallrd during cardiogenesis, while Walrad is mainly expressed in the left atrium in the adulthood. (H–I) Rt-qPCR analyses of Wnt11 and Wnt8a expression during cardiogenesis. Three embryonic hearts were pooled on each developmental time and three distinct neonatal and adult hearts were used for RNA isolation, respectively. Three independent biological assays were analyzed in each case
