Current studies revealed that Tumor Protein P53 (TP53), Mesenchymal Epithelial Transition Proto-Oncogene (MET), B-Raf Proto-Oncogene (BRAF), and Kirsten Rat Sarcoma Viral Oncogene (KRAS), which were commonly altered genes of lung cancer, were mutant or upregulated in IPF patients [46, 47]. Here, TP53 is linked to lung carcinoma.
