The prostate adenocarcinoma (TCGA, Provisional) (Figure 3A), lung adenocarcinoma (TCGA, Provisional) (Figure 3B), head and neck squamous cell carcinoma (TCGA, Provisional) (Figure 3C), lung squamous cell carcinoma (TCGA, Provisional) (Figure 3D), kidney renal clear cell carcinoma (TCGA, Provisional) (Figure 3E), and cervical squamous cell carcinoma and endocervical adenocarcinoma (TCGA, Provisional) (Figure 3F) databases were selected to observe the relationship between PinX1 gene copy number and mRNA levels. Here, PINX1 is linked to squamous cell lung carcinoma.
