In addition, we found that T‐025 showed high in vitro growth suppressive effect in an additional cancer cell line with higher CLK2 protein, that is, lung cancer NCI‐H1048; also, T‐025 caused moderate anti‐proliferative effect in normal fibroblast cell lines with lower CLK2 protein (Fig 4B). The gene discussed is CLK2; the disease is lung carcinoma.
