Vertical stacked bars from QPCR profiling showing the regulation of FIR-amplified stem cell-related transcription with PT-EA treatment in ALDH+CD44+CD24+ PC-CSCs derived from xenografts established using MiaPaCa-2, Panc-1, Panc-3.27, and BXPC-3. Inhibitory potential of PT-EA was compared for the 43 genes that showed cell line-independent increase after fractionated radiation across all four PC-CSC clones investigated. Cell line-independent effect of PT-EA for any given gene is indicated with “‡” for four, with “†” for three, and with “*” for two PC-CSC clones; “∆” for cell line-dependent effect. In the stacked bar, PT-EA + FIR bars are overlaid on top of the FIR bars and the y axis is restricted to a maximum of 20-fold for better presentation of comparative display. Overall, PT-EA treatment exerted cell line-independent inhibition of 10 of the 43 FIR-induced genes (ALDH2, APC, AXIN1, DVL1, FGFR1, GJB2, HRAS, ISL1, TBX2, TUBB3).
