Quick Overview

Human ovarian cancer cell line with BRCA2 mutations and platinum resistance.

Detailed Summary

PEO1 is a human ovarian cancer cell line derived from a patient with high-grade serous ovarian carcinoma. It is characterized by a BRCA2 germline mutation and has been extensively studied for its role in platinum resistance and drug sensitivity. PEO1 is commonly used in research on DNA repair mechanisms, particularly in the context of homologous recombination deficiency. The cell line has been utilized in studies investigating the molecular basis of chemotherapy resistance and the development of targeted therapies. PEO1 is also notable for its use in understanding the functional restoration of BRCA2 through secondary mutations, which can influence drug response and resistance patterns.
