Combining Go analysis and hierarchical networks of the abundance of GO terms using REVIGO, we predicted the enriched cellular processes in HFpEF after CKD were mainly clustered into four categories: inflammatory response including chemotaxis, cytokine binding, ion transport including potassium channel binding, cation channel activity, extracellular matrix including collagen trimer and others (Fig. S2B). The gene discussed is KCNA3; the disease is chronic kidney disease.
