Western blot assays revealed that forced LINC01138 expression in colon cancer cells SW480 increased the expression of diacylglycerol kinase eta (DGKH) and Phosphodiesterase 4D (PDE4D), whereas resulted in decrease the expression of pyrroline‐5‐carboxylate reductase 1 (PYCR1) and transketolase (TKT). The gene discussed is PDE4D; the disease is colonic neoplasm.
