Updated project metadata. The aim of the study was to characterize a common molecular mechanism for paclitaxel resistance in Patu-T and Suit-2.028 PDAC cell lines. Despite the ATP-binding cassette (ABC) trasnsporters were already shown to be involved in various chemo-resistant forms of cancers but not in PDAC, the most likely impact of ABCB1 overexpression in PDAC cell models was taken into account in this dataset.
