UQL = under quantification limit (>0.05 copy/ng total RNA for PEPT1; >0.5 copy/ng total RNA for PEPT2).
Expression levels are reported as copy/ng total RNA (mean ± SD; n = 4). Determinations were performed in duplicate on each sample by 2-step real-time quantitative PCR using complementary DNA obtained by reverse transcription from total RNA of human cancer cell lines.
