作者： Uri Ben-David1,2 Alva Biran2 Paola Scaffidi3,4,5 Christel Herold-Mende6 Markus Boehringer7 eran Meshorer2 Nissim Benvenisty1,2 Stem Cell Unit Silberman Institute of Life Sciences The Hebrew University Jerusalem 91904 Israel Department of Genetics Silberman Institute of Life Sciences The Hebrew University Jerusalem 91904 Israel National Cancer Institute NIH Bethesda MD 20892 USA UCL Cancer Institute University College London London WC1E 6BT UK Cancer Research UK London Research Institute London WC2A 3LY UK Division of Neurosurgical Research Department of Neurosurgery University of Heidelberg Heidelberg Germany F.

We have previously shown that fibroblasts resistant to SCD1 inhibition acquire the metabolic sensitivity when reprogrammed into induced PSCs, but this sensitivity is quickly lost upon differentiation (Ben-David et al., 2013). Here we demonstrate that these fibroblasts acquire the same metabolic vulnerability when they are transformed into undifferentiated stem cell-like cancer cells, but the resistance to SCD1 inhibition is conferred again once cancer cells are induced to differentiate (Figure 1I). These findings link, for the first time, the differentiation state of cancer cells with their response to inhibition of oleate synthesis, suggesting that SCD1 inhibition might be an especially effective cancer therapy for undifferentiated tumor types. This work also demonstrates that research on cellular reprogramming can yield insights into cancer biology, and validates that in vitro generated CSCs can be successfully used for screening anticancer drugs.
