PTPA and lung cancer: By analyzing the nearest genes to the PP2A-overlapping DAPs in chromosome 19 (Table S5), we identified, for example, ferroptosis regulator GPX (Doll et al, 2019), strongly implicated in lung cancer progression and metastasis (Zou et al, 2021), or MAPKK MKK7 (MAP2K7), which is an upstream regulator of JNK driving lung tumorigenesis downstream of RAS (Ruiz et al, 2021).
