In this study, the results of bioinformatics mining not only demonstrate the high expression of DCTPP1 in ovarian cancer and its correlation with disease prognosis, but also suggest its principal biological function to be centred around nucleotide metabolism, particularly in the regulation of pyrimidine metabolism, involving the P53 signalling pathway, cell cycle and drug metabolism. This evidence concerns the gene DCTPP1 and ovarian carcinoma.
