Abstract:
Uterine papillary serous adenocarcinoma (UPSC) is an uncommon histologic subtype of endometrial cancer that characteristically behaves aggressively with a poor prognosis. We established two novel cell lines derived from UPSC designated HEC-155 and HEC-180. Both cell lines have been growing steadily in monolayer cultures for over ten years. Overexpression of p53, Ki67 and p27 was detected in both cell lines by immunohistochemistry. Using a DNA sequencing technique, a point mutation of p53 was detected in exon 8, codon 286 in HEC-155 and in exon 6, codon 195 in HEC-180. These newly established cell lines should be useful for investigating the characteristics of UPSC.
