Detection of the novel mitochondrial/genomic DNA fusion gene ND4-PLAG1. a Illustration of ND4-PLAG1. MT mitochondrial. b PCRs of genomic DNA extracted from the ND4-PLAG1-positive tumor (case 38) and a fusion-negative tumor (case 39), using the denoted primer pairs. Of the 882 bp PCR product of primers 4F and 1R, 591 bp are mitochondrial and 291 bp are nuclear DNA. c PCRs of cDNA extracted from tumor 38 and 39
