Despite differences in CNV patterns between C10 malignant cells and lung‐ciliated cells (Figure 3g), C10 malignant cells exhibited high expression of motile cilia‐related genes, including DNAH7 and CFAP54 in BRCA, LUAD, COAD_READ and ESCA; CFAP47 and HYDIN in HCC; DNAH6 and DNAH7 in ICC; CFAP54 and DNAH6 in STAD, similar to those found in lung ciliated cells (Figure 3h,i). The gene discussed is CFAP47; the disease is intrahepatic cholangiocarcinoma.
