PARP1 and neoplasm: Correlation analysis between the expression of the six prognosis genes and the sensitivity of anti-tumor drugs was performed based on the CellMiner database (https://discover.nci.nih.gov/cellminer/), and the results indicated that our signature genes were moderately correlated with the response of some common anti-tumor drugs such as PARP inhibitor (Olaparlib), chemotherapy drugs (Fluorouracil, Decitabine, Oxaliplatin), which might imply potential value in anti-tumor therapy (Figure 11).
