Pan-cancer multi-omics analysis reveals upregulation of the POLE2 subunit of DNA polymerase epsilon and its associations with patient survival and cellular pathways beyond DNA replication
Abstract DNA polymerase epsilon (Polε) is essential for high-fidelity leading-strand synthesis. It comprises a catalytic subunit, POLE, and three accessory subunits, including POLE2. In contrast to POLE, the biological functions and clinical significance of POLE2 remain unexplored. POLE2 is vital for the assembly of Po...
