However, from our array CGH and gene expression array data, p53 was located in the chr17:7,175,150-8,229,647 genomic amplification region and was over-expressed at the mRNA level (the median of the expression of p53 in cervical cancer cell lines was 1.316 [from 0.82 to 3.38); the median of the expression of p53 in normal cervical epithelium was 0.295 [from 0.153 to 0.485]). The gene discussed is TP53; the disease is cervical cancer.
