DPP7 and breast cancer: Genes coexpressed with DPP7 were involved in cell cycle-related pathways and networks such as “Cell cycle_Role of SCF complex in cell cycle regulation”, “DNA damage_ATM/ATR regulation of G1/S checkpoint”, ”Cell cycle_Role of APC in cell cycle regulation“, ”Cell cycle_Spindle assembly and chromosome separation”, and “Cell cycle_Chromosome condensation in prometaphase“ playing essential roles in breast cancer patients (Supplementary Figure S6, Table S4).
