Abstract
Nucleoside-based drugs, recognized as purine or pyrimidine analogs, have been potent therapeutic agents since their introduction in 1950, deployed widely in the treatment of diverse diseases such as cancers, myelodysplastic syndromes, multiple sclerosis, and viral infections. These antimetabolites establish complex interactions with cellular molecular constituents, primarily via activation of phosphorylation cascades leading to consequential interactions with nucleic acids. However, the therapeutic efficacy of these agents is frequently compromised by the development of drug resistance, a continually emerging challenge in their clinical application. This comprehensive review explores the mechanisms of resistance to nucleoside-based drugs, encompassing a wide spectrum of phenomena from alterations in membrane transporters and activating kinases to changes in drug elimination strategies and DNA damage repair mechanisms. The critical analysis in this review underlines complex interactions of drug and cell and also guides towards novel therapeutic strategies to counteract resistance. The development of targeted therapies, novel nucleoside analogs, and synergistic drug combinations are promising approaches to restore tumor sensitivity and improve patient outcomes.

Abstract
Nucleobase and nucleoside analogs (NAs) play important roles in cancer therapy. Although there are obvious individual differences in NA treatments, most NAs lack direct relationships between their plasma concentration and efficacy or adverse effects. Accumulating evidence suggests that the intracellular active metabolite levels of NAs predict patient outcomes. This article reviewed the relationships between NA intracellular active metabolite levels and their efficacy or adverse effects. The factors affecting the formation of intracellular active metabolites and combination regimens that elevate intracellular active metabolite levels were also reviewed. Given the mechanism of NA cytotoxicity, NA intracellular active metabolite levels may be predictive of clinical outcomes. Many clinical studies support this hypothesis. Therefore, the monitoring of intracellular active metabolite levels is beneficial for individualized NA treatment. However, to perform clinical monitoring in practice, well-designed studies are needed to explore the optimal threshold or range and the appropriate regimen adjustment strategies based on these parameters.

J Biol Chem 2016; 291:18809-17.

Abstract
Human nucleoside transporters (hNTs) mediate cellular influx of anticancer nucleoside drugs, including cytarabine, cladribine, and fludarabine. BCR-ABL tyrosine kinase inhibitors (TKIs) imatinib and dasatinib inhibit fludarabine and cytarabine uptake. We assessed interactions of bosutinib, dasatinib, imatinib, nilotinib, and ponatinib with recombinant hNTs (hENT1, 2; hCNT1, -2, and -3) produced individually in yeast Saccharomyces cerevisiae Nilotinib inhibited hENT1-mediated uridine transport most potently (IC50 value, 0.7 μm) followed by ponatinib > bosutinib > dasatinib > imatinib. Imatinib inhibited hCNT2 with an IC50 value of 2.3 μm Ponatinib inhibited all five hNTs with the greatest effect seen for hENT1 (IC50 value, 9 μm). TKIs inhibited [(3)H]uridine uptake in a competitive manner. Studies in yeast with mutants at two amino acid residues of hENT1 (L442I, L442T, M33A, M33A/L442I) previously shown to be involved in uridine and dipyridamole binding, suggested that BCR-ABL TKIs interacted with Met(33) (TM1) and Leu(442) (TM11) residues of hENT1. In cultured human CEM lymphoblastoid cells, which possess a single hNT type (hENT1), accumulation of [(3)H]cytarabine, [(3)H]cladribine, or [(3)H]fludarabine was reduced by each of the five TKIs, and also caused a reduction in cell surface expression of hENT1 protein. In conclusion, BCR-ABL TKIs variously inhibit five different hNTs, cause a decrease in cell surface hENT1 expression, and decrease uridine accumulation when presented together with uridine or when given before uridine. In experiments with mutant hENT1, we showed for the first time interaction of Met(33) (involved in dipyridamole binding) with BCR-ABL inhibitors and reduced interaction with M33A mutant hENT1.

Abstract
BACKGROUND The aim of this study was to compare the T lymphocyte subsets of chronic myelogenous leukemia (CML) patients who had a complete cytogenetic response (CCyR) after treatment with imatinib (IM) or homoharringtonine (HHT). METHODS T and Th lymphocyte subsets in CCyR patients treated with HHT (n = 15) or IM (n = 16) were assayed with flow cytometry. RESULTS It was found that there were no differences in T lymphocyte subset proportions at the time of achieving CCyR0 and also no difference in the CD8+T cell proportions at the 12th month after CCyR (CCyR12), between the 2 groups. The values of CD3+T, CD4+T, CD8+T, CD4+T/CD8+T, Th1 and Th2 cells were 54.21% ± 6.12% vs. 44.32% ± 4.85%, 29.83% ± 5.53% vs. 22.27% ± 3.22%, 24.66 ± 4.91 vs. 25.41% ± 5.72% , 1.11 ± 0.23 vs. 0.92 ± 0.19, 10.23% ± 4.24% vs. 8.34% ± 3.45% and 11.12% ± 3.91% vs. 13.67% ± 4.78%, respectively in the HHT group and IM group at CCyR12, which meant that the proportions of CD3+T, CD4+T and Th1 cells and the ratio of CD4+T to CD8+T cells were higher and the CD8+T and Th2 cell proportions were lower in the HHT group than in the IM group. CONCLUSIONS HHT has a weaker immunodepression effect on T lymphocyte subsets compared with IM.

Abstract
INTRODUCTION Small molecule tyrosine and serine-threonine kinase inhibitors (TKIs and STKIs) are emerging drugs that interfere with downstream signaling pathways involved in cancer proliferation, invasion, metastasis and angiogenesis. The understanding of their pharmacokinetics, the identification of their transporters and the modulating activity exerted on transporters is pivotal to predict therapy efficacy and to avoid unwarranted drug treatment combinations. AREAS COVERED Experimental or in silico data were collected and summarized on TKIs and STKIs physico-chemical properties, which influence their transport, metabolism and efficacy, and TKIs and STKIs as influx transporter substrates and inhibitors. In addition, the uptake by tumor cell influx transporters and some factors in the tumor microenvironment affecting the uptake of TKIs and STKIs by cancer cells are briefly covered. EXPERT OPINION Membrane transporters play an important role in the pharmacokinetics and hence the efficacy of anticancer drugs, including TKIs and STKIs. These drugs are substrates and inhibitors of various transporters. Drug resistance may be bypassed not only by identifying the proper transporter but also by selective combinations, which may either downregulate or increase transporter activity. However, care has to be taken because this profile might be disease, drug and patient specific.

Abstract
PURPOSE Combinations of tyrosine kinase inhibitors (TKI) with gemcitabine have been attempted with little added benefit to patients. We hypothesized that TKIs designed to bind to ATP-binding pockets of growth factor receptors also bind to transporter proteins that recognize nucleosides. EXPERIMENTAL DESIGN TKI inhibition of uridine transport was studied with recombinant human (h) equilibrative (E) and concentrative (C) nucleoside transporters (hENT, hCNT) produced individually in yeast. TKIs effects on uridine transport, gemcitabine accumulation, regulation of hENT1 activity, and cell viability in the presence or absence of gemcitabine were evaluated in human pancreatic and lung cancer cell lines. RESULTS Erlotinib, gefitinib and vandetanib inhibited [(3)H]uridine transport in yeast and [(3)H]uridine and [(3)H]gemcitabine uptake in the four cell lines. Treatment of cell lines with erlotinib, gefitinib, or vandetanib for 24 hours reduced hENT1 activity which was reversed by subsequent incubation in drug-free media for 24 hours. Greater cytotoxicity was observed when gemcitabine was administered before erlotinib, gefitinib, or vandetanib than when administered together and synergy, evaluated using the CalcuSyn Software, was observed in three cell lines resulting in combination indices under 0.6 at 50% reduction of cell growth. CONCLUSIONS Vandetanib inhibited hENT1, hENT2, hCNT1, hCNT2, and hCNT3, whereas erlotinib inhibited hENT1 and hCNT3 and gefitinib inhibited hENT1 and hCNT1. The potential for reduced accumulation of nucleoside chemotherapy drugs in tumor tissues due to inhibition of hENTs and/or hCNTs by TKIs indicates that pharmacokinetic properties of these agents must be considered when scheduling TKIs and nucleoside chemotherapy in combination.

Abstract
Resistance to 5-fluorouracil (5FU) poses a constant challenge to the management of colorectal cancer (CRC). Consistent efforts were called for to identify molecular markers that can effectively predict patients' response. This study investigated the role of nucleoside transporters, particularly human equilibrative nucleoside transporter 1 (hENT1), in predicting clinical treatment outcome with 5FU-based therapy. Expression of a panel of nucleoside transporters in biopsied tumors from 7 CRC patients was measured by real-time PCR prior to 5FU-based chemotherapy. To provide mechanistic support for the role of hENT1 in 5FU resistance, cell viability of Caco-2 cells was measured, following incubation with varying concentrations of 5FU and a hENT1 inhibitor. Biopsied tumors were further subjected to global metabonomic profiling using gas chromatography/mass spectrometry. High hENT1 levels in tumor tissue correlated with poor clinical response to 5FU. Corroborating with the clinical findings, chemical inhibition of hENT1 in Caco-2 cells resulted in an augmentation of 5FU efficacy. Metabonomic profiling revealed that the pretreatment metabotype associated with non-responders to 5FU therapy was distinct from metabotype of responders (partial least-squares discriminant analysis Q(2) (cumulative) = 0.898, R(2)X = 0.513, R(2)Y = 0.996). This is the first clinical report on the relationships of intratumoral expression of nucleoside transporters and tumor metabotype with response to 5FU among CRC patients. Coupled to the in vitro findings, our preliminary data suggested hENT1 to be a potential codeterminant of clinical response to 5FU.
