TP53 and urinary bladder carcinoma: Similarly, the D-isomer of the p53 C-terminus, presumably able to interact with and modulate the conformation of mutant p53, connected to a retro-inverso version of the NH2-terminal 20-amino acid peptide of the influenza virus hemagglutinin-2 protein with a poly-arginine CPP, was able to inhibit growth of bladder cancer after a single application [61].
