TP53 and cancer: Checking the above data against the UMD TP53 mutation database (http://www.p53.fr/) and revising the article by Berglind et al. [75], we could not find correlation between a given MJ-mediated phase arrest of cell cycle and the TP53 wild type or mutated status of a cancer cell type (data not shown), a result that would agree with the original observation of Fingrut and Flescher [15] stating that MJ-mediated cell death is independent of the p53 status [17].
