As a final point of analysis, the current study aimed to investigate the molecular mechanism of CHD1L in tumor progression where the top 50 interacting proteins and top 100 correlated proteins to CHD1L in the tumor tissue were obtained from STRING and GEPIA2 databases respectively and we interestingly found that PARP1 was a common protein in both of the generated datasets. This evidence concerns the gene PARP1 and neoplasm.
