Indeed, the results indicated that PTEN knockout significantly increased the mRNA levels of most of the ciliated genes, namely, Cep126, Dcdc2a, Dnaic2, Dnah5, Foxj1, Hydin, Tctex1d4, Spag16, and Wdr63, implying that loss of PTEN may be involved in ciliogenesis during EGFRL858R-induced lung cancer progression (Fig. 3A). The gene discussed is HYDIN; the disease is lung cancer.
