Panel A. Alignment of the sequences of the FHC mRNA and the FTH1P3 pseudogene from nt. 271 to nt. 720. The FHC accession number is NM_002032.2. The FTH1P3 accession number is NR_002201.1. The ΨF, ΨR, HF and HR oligonucleotide sequences are boxed. Panel B. PCR analysis of FTH1P3 transcript, performed with ΨF and ΨR oligonucleotides. Lane 1: genomic DNA from MCF-7 cells; lane 2: DNaseI-treated total RNA from MCF-7 cells; lane 3: cDNA from MCF-7 cells; lane 4: negative control without template (NC). The predicted PCR product, indicated by an arrow, is 87-bp long. DNA sequencing electropherogram (nt. 38 to nt. 63) of the FTH1P3 fragment. Panel C. PCR analysis of FTH1P3 transcript, performed with HF/ΨR (lane 1), negative control without template (lane 2). The predicted PCR product, indicated by arrow is 260-bp long. DNA sequencing electropherogram (nt. 139 to nt. 173) of the 260-bp FTH1P3 fragment. Panel D. PCR analysis of FTH1P3 transcript elongated with ΨF/HR oligonucleotides (lane 1), negative control without template (lane 2). The predicted PCR products, indicated by arrows, are 149-bp for FTH1P3 and 117-bp for FHC. DNA sequencing electropherogram (nt. 20 to nt. 54) of the 149-bp FTH1P3 fragment and of the 117-bp FHC fragment (nt. 35 to nt. 55).
