For example, the Fas cell surface death receptor is related to apoptosis,31 activating T cell killing,32 and resistance in tumor-immune conflict in colorectal cancer,33 while the BCL2-associated X, an apoptosis regulator, is key to apoptosis34 and p53 transcription pathways in lung cancer35 and also correlates with chemoresistance to cisplatin.36 This evidence concerns the gene TP53 and colorectal cancer.
