EPB41L4A and neoplasm: EPB41L4A-AS2 expression was correlated with tumor-associated biological processes, including G-protein coupled receptor signaling pathways, CAAX-box protein processing, negative regulation of histone deacetylation, the MDA-5 signaling pathway, the RIG-I signaling pathway, and cell cycle checkpoints (all p < 0.05; Figure 5A).
