TranscriptomicsRole of Aldoketoreductases and Other Doxorubicin Pharmacokinetic Genes in Doxorubicin Resistance, DNA binding, and Subcellular Localization
Objective: To assess the role of aldoketoreductases and other doxorubicin pharmacokinetic or pharmacogenomic genes in doxorubicin cytotoxicity, resistance, DNA binding activity, and subcellular localization, Methods: We conducted a whole genome microarray study to identify differences in betwee...

TranscriptomicsDistinct genetic alterations occur in ovarian tumor cells selected for combined resistance to carboplatin and docetaxel
Background: Current protocols for the treatment of ovarian cancer include combination chemotherapy with a platinating agent and a taxane. However, many patients experience relapse of their cancer and the development of drug resistance is not uncommon, making successful second line therapy difficult ...

TranscriptomicsNCIC CTG MA.22 phase I/II trial of epirubicin and docetaxel in locally advanced breast cancer on 2-weekly or 3-weekly schedules
This phase I/II neoadjuvant trial determined maximally-tolerated doses (MTD), dose-limiting toxicities (DLT), response-to-therapy, and explored the role of new response biomarkers. The combination regimens were delivered with acceptable toxicity, good clinical response, inducing changes in tumor RNA...

TranscriptomicsAlterations in tumour necrosis factor signaling pathways associated with cytotoxicity and resistance to taxanes in tumour cells.
The taxanes are widely used in the treatment of breast and other cancers. While their cytotoxicity has been attributed to the induction of cell cycle arrest in mitosis through the stabilization of microtubules, we found that docetaxel promotes soluble tumor necrosis factor alpha (TNF-alpha producti...

TranscriptomicsInduction of 1C Aldoketoreductases and Other Drug Dose-dependent Genes Upon Acquisition of Anthracycline Resistance
Recent studies have suggested that elevated expression of aldoketoreductase (AKR) 1C1 or 1C2 in tumour cells is associated with increased resistance to DNA damaging agents such as cisplatin and doxorubicin. However, it has not been shown whether selection of tumour cells for resistance to DNA-damag...
