Using a genetically defined human ovarian cancer model, we have analyzed the protein expression profile of human ovarian cancer cells established by oncogenic RAS transformation. Cells were immortalized by retroviral transfection of SV40 t/T antigens and the catalytic subunit of telomerase (hTERT). Careful analyses of protein targets associated with oncogenic transformation have enabled us to identify several novel signaling pathways that play important roles in oncogenic transformation of…

Prognostic significance of APE1 cytoplasmic localization in human epithelial ovarian cancer
- Biology, MedicineMedical Oncology
- 2011
It is found that cytoplasmic localization of APE1 is associated with tumor progression and might be a valuable prognostic marker for EOC, and a lower survival rate was found in patients with cytop lasmic positive localization of apurinic/apyrimidinic endonuclease 1.
