RYR2 and cancer: A manual check of these 286 deregulated genes (RyR2 associated DEG) revealed enrichment in cancer metastasis (68 genes), brain‐ or heart‐biased expression (35 genes), transcription regulation (23 genes), ROS related function (21 genes), cytoskeleton or extracellular matrix (ECM) (18 genes), ion channel or transporters (13 genes) (Fig. 5B).
