Comparison of the expression of human equilibrative nucleotide transporter 1 (hENT1) and ribonucleotide reductase subunit M1 (RRM1) genes in seven non-Hodgkin lymphoma cell lines

We investigated the variability in the expression of human equilibrative nucleoside transporter 1 (hENT1) and ribonucleotide reductase subunit M1 (RRM1) in non-Hodgkin lymphoma cell lines. hENT1 and RRM1 mRNA expression levels in natural killer (NK) cells and seven non-Hodgkin lymphoma cell lines (YTS, SNK-6, Jeko-1, ly-1, Raji, Karpas, and Jurket) were studied using reverse-transcription quantitative real-time polymerase chain reaction (RT-qPCR) and the results were compared using the Student t-test. mRNA expression of hENT1 was detectable in YTS, SNK-6, Jeko-1, ly-1, Raji, Karpas, Jurket, and NK cells, which revealed variability in gene expression. There were significant differences in the mRNA expression values of hENT1 (P = 0.021) and RRM1 (P = 0.002) compared to those in NK cells. mRNA expression of both hENT1 and RRM1 was closely associated with non-Hodgkin lymphoma cell proliferation. Differential expression analysis of hENT1 and RRM1 in non-Hodgkin lymphoma cell lines may provide novel drug leads for precision medicine.
