MSP analysis of p14/ARF for different patients with colorectal cancer; U and M indicates the U and the M fragments, respectively. Lanes L, ladder at 1,500 bp; NC, negative control of PCR (without primers); 1, positive controls of U reaction; 2, positive controls of M reaction. For patient 1, lanes 3 and 4 reveal the presence of U band and the absence of M band, respectively. For patient 2, lanes 5 and 6 reveal the presence of the U and M band respectively in the same tumor. Patient 3 reveals the absence of U band and the presence of M band (M) in lanes 7 and 8, respectively. Inset, comparison report of density of UM and MU pattern of p14/ARF
