In this study, epithelial ovarian cancer (EOC) cells and the same cell line resistant to cisplatin, fifteen calcium-associated genes (IP3R1/2/3, RYR1/2, SERCA1/2/3, NCX1/2/3, and PMCA1/2/3/4) expressions were examined using the quantitative reverse transcription-polymerase chain reaction (RT-PCR) method. This evidence concerns the gene ITPR1 and ovarian carcinoma.
