MYC, TP53, and Chromosome 17 Copy-Number Alterations in Multiple Gastric Cancer Cell Lines and in Their Parental Primary Tumors

Figure 1

Fluorescence in situ hybridization assay. (a) Interphase nuclei presenting two MYC signals from normal gastric mucosa; (b) interphase nuclei presenting 2–5 MYC signals from ACP02 parental primary tumor; (c) interphase nuclei presenting MYC signal number alterations, including high amplification, from the 85th passage of AGP01 cell line; (d) interphase and metaphase cells presenting two copies of chr17/TP53 from lymphocytes control, with the green spots representing the 17 centromere probe and the red representing the TP53 gene probe; (e) interphase nuclei presenting two signals of chr17 and two or one TP53 signal(s) from ACP02 parental primary tumor; (f) interphase nuclei presenting three signals for chr17 and two TP53 signals from the 85th passage of ACP03 cell line.
