Human Equilibrative Nucleoside Transporter 1 (hENT1) in Pancreatic Adenocarcinoma: Towards Individualized Treatment Decisions
Pancreatic cancer is one of the most lethal cancers, where curative surgical resections are rare and less than 5% of patients experience long-term survival. Despite numerous clinical trials, improvements in the systemic treatment of this disease have been limited. Gemcitabine, a nucleoside analogue, is still considered the standard of care chemotherapy for most patients in the advanced disease ...
متن کاملNucleobase transport by human equilibrative nucleoside transporter 1 (hENT1).
The human equilibrative nucleoside transporters hENT1 and hENT2 (each with 456 residues) are 40% identical in amino acid sequence and contain 11 putative transmembrane helices. Both transport purine and pyrimidine nucleosides and are distinguished functionally by a difference in sensitivity to inhibition by nanomolar concentrations of nitrobenzylmercaptopurine ribonucleoside (NBMPR), hENT1 bein...
متن کاملHuman equilibrative nucleoside transporter 1 (hENT1) protein is associated with short survival in resected ampullary cancer.
BACKGROUND Gemcitabine is an acceptable alternative to best supportive care in the treatment of advanced biliary tract cancers. The human equilibrative nucleoside transporter 1 (hENT1) is a ubiquitous protein and is the major means by which gemcitabine enters human cells. Moreover, recent reports indicate a significant correlation between immunohistochemical variations of hENT1 in tumor samples...
متن کاملA predictive analysis of the SP120 and 10D7G2 antibodies for human equilibrative nucleoside transporter 1 (hENT1) in pancreatic ductal adenocarcinoma treated with adjuvant gemcitabine
Expression of human equilibrative nucleoside transporter 1 (hENT1) in pancreatic ductal adenocarcinoma (PDAC) has been postulated to be a marker of sensitivity to gemcitabine. However, heterogeneity in the studies attempting to quantify hENT1 expression in patients with PDAC treated with gemcitabine has yielded inconclusive results that impede the adoption of hENT1 expression as a predictive bi...
متن کاملHuman equilibrative nucleoside transporter 1, as a predictor of 5-fluorouracil resistance in human pancreatic cancer.
BACKGROUND The purpose of this study was to find a novel biomarker to predict 5-fluorouracil (5-FU) or gemcitabine (2',2'-difluoro-deoxycytidine) sensitivity in pancreatic cancer. MATERIALS AND METHODS The relationship between 5-FU and gemcitabine sensitivity and the mRNA levels of human equilibrative nucleoside transporter 1 (hENT1), thymidylate synthase (TS) and dihydropyrimidine dehydrogen...
