Using a randomized crossover design and continuous variables such as change in hearing threshold and biomarkers of acute renal injury as short-term endpoints, it was determined that pantoprazole, an organic cation transporter 2 inhibitor, did not ameliorate cisplatin-associated nephrotoxicity or ototoxicity.Cystatin C is a robust method to estimate glomerular filtration rate in patients with cancer.
Collectively, these preclinical data provide evidence for a direct effect of metformin <i>in vivo</i> and suggest that OCT2 expression may predict metformin uptake and tumor response.<i>Cancer </i>.
Using data obtained from the cancer transcriptome database Oncomine and the proteome database The Human Protein Atlas, we identified the repression of organic cation transporter OCT2 as a potential factor contributing to oxaliplatin resistance in RCC.
