Barcode Sequencing Data of Capecitabine Resistant Caco-2 and Irinotecan Resistant HT-29 Cell Lines
Caco-2 and HT-29 cells were barcoded using the CloneTracker lentiviral barcode library and then irinotecan and capecitabine resistant derivatives of these cell lines were established. Four million barcoded Caco-2 and HT-29 cell were seeded into 15 cm cell culture dishes. When the cells reached confluency, two million cells per dish were seeded into four different 15 cm dishes with 25 mL medium (DMSO Control, Replica A, B, C) and two million cell pellets were stocked as initial cell population.For Caco-2 cell line, mediums in the dishes were changed twice a week with fresh mediums containing IC50 dose (4 months) and subsequently 2x IC50 dose (2 months) of capecitabine, for HT-29 cell line IC50 dose (6 months) of irinotecan. Caco-2 and HT-29 cell lines treated with DMSO were given the same amount of DMSO used in dissolving compounds as fresh medium. Following the end points of six months for each cell line, DNA isolation from harvested cell lines and collected medium of resistant B cell lines were carried out and barcodes were sequenced.
