TDG and plasma cell myeloma: A limitednumber of studies have assessed TDG expression levels in tumors.Nettersheim et al. (32) reported high levels ofTDG and TET transcripts in germ cell-derivedtumors, while Peng et al. (33) reported thatTDG hypermethylation and the consequent reduction of transcriptexpression led to an impairment of repair in multiple myeloma cell lines.
