Figure 3: Expression of FANCLΔ4 and FANCL isoforms in BRCAX cell lines. mRNA expression levels of FANCLΔ4 and FANCL isoforms in BRCAX cell lines as measured by quantitative real-time PCR experiments. Expression levels are expressed in (A) copy number and (B) FANCLΔ4/FANCL expression ratios. In (A) the numbers at the top of the columns indicated the relative expression of each isoform (%), while in (B) the number indicated the fold change based on the Heterozygotes (Het) normalized at 1.0.
