XRCC1 and glioma: The authors have proposed that genes involved in the cell cycle and DNA restoration have a crucial involvement in glioma development, like glutathione S-transferases (GSTs), excision repair cross-complementing rodent repair deficiency complementation group 1 (ERCC1), X-ray repair cross-complementing groups 3 (XRCC3), and X-ray repair cross-complementing groups 1 (XRCC1) [25-27].
