We examined the frame of reference of auditory responses in the inferior colliculus in monkeys fixating visual stimuli at different locations. Eye position modulated the level of auditory responses in 33% of the neurons we encountered, but it did not appear to shift their spatial tuning. The effect of eye position on auditory responses was(More)
PURPOSE Our previous studies showed that combined treatment of oxaliplatin and N(1), N(11) diethyl-norspermine (DENSPM) results in massive induction of spermidine/spermine N(1)-acetyltransferase (SSAT) mRNA and activity. Since oxaliplatin and 5-fluorouracil (5FU) are used clinically in treatment of colorectal cancers, this study examines the effect of(More)
A great deal of experimental evidence connects induction of polyamine catabolism via spermidine/spermine N1-acetyltransferase (SSAT) to antiproliferative activity and apoptosis. Following our initial observation from gene expression profiling that platinum drugs induce SSAT, we undertook this present study to characterize platinum drug induction of SSAT and(More)
The efficacy of platinum drugs in the treatment of cancer is often restricted by the acquisition of tumor cell resistance subsequent to treatment. To better understand mechanisms involved in this phenomenon, a clonal subline (A2780/C10B) isolated from an oxaliplatin-resistant human ovarian carcinoma cell line (A2780/C10) was developed, as reported(More)
PURPOSE As a follow-up to our previous findings that platinum drugs induce a key enzyme in polyamine catabolism, gene expression profiling and mathematical modeling were used to define the effects of cisplatin and oxaliplatin on the expression of polyamine metabolic pathway genes in A2780 human ovarian carcinoma cells. METHODS Time-course and(More)
A single cell clonal sub-line A2780/C10B that is 18-fold resistant to oxaliplatin and approximately threefold cross-resistant to cisplatin and exhibiting a metastasis associated cellular phenotype was characterized for mechanisms of resistance. The cell line exhibited a 50% reduction in the accumulation of both oxaliplatin and cisplatin relative to the(More)
PURPOSE To understand the mechanisms behind platinum drug/DENSPM-induced inhibition of cancer cell growth, we compared the effects of oxaliplatin and cisplatin when combined with DENSPM on the induction of SSAT mRNA, activity, polyamines and cell growth in A2780 human ovarian carcinoma cells and their oxaliplatin- and cisplatin-resistant variants A2780/C10B(More)
PURPOSE To determine the maximal tolerated dose of capecitabine with oxaliplatin + radiotherapy in a phase I study of localized esophageal cancer. PATIENTS AND METHODS Oxaliplatin (85 mg/m(2)) administered on days 1, 15, and 29. Capecitabine administered twice daily 5 days weekly; dose levels (DL) were 1, 1000; 2, 1250; and 3, 1500 mg/m(2) with 50.4 Gy(More)
275 Background: TACE and anti-angiogenic agents have individually been effective in inoperable HCC. In this prospective phase 2 study, the effects and PFS of Su+TACE was evaluated. METHODS Eligibility: ECOG PS 0, 1, inoperable HCC, Child Pugh (CP) A/B, platelets >100K, bilirubin < 2 and no contraindications to TACE. TREATMENT Cycle (C) 1 -Su 37.5mg po(More)
BACKGROUND AND OBJECTIVES No evaluation of sex and race influences on mycophenolic acid (MPA) pharmacokinetics and adverse effects (AEs) during enteric-coated mycophenolate sodium (ECMPS) and tacrolimus immunosuppression are available. The primary objective of this study was to investigate the influence of sex and race on MPA and MPA glucuronide (MPAG)(More)
