Gene Expression Analysis based on snRNAseq data in PITX2-deficient and control human iPSCs.. PITX2-KO_hiPSC_snRNAseq

Reduced left atrial PITX2 is associated with atrial cardiomyopathy and atrial fibrillation. PITX2 is restricted to left atrial cardiomyocytes in the adult heart. The links between PITX2 deficiency, atrial cardiomyopathy and atrial fibrillation are not fully understood. Methods. To identify mechanisms linking PITX2 deficiency to atrial fibrillation, we generated and characterized PITX2-deficient human atrial cardiomyocytes (aCMs) derived from human induced pluripotent stem cells and their controls.
