Ewing's sarcoma‐derived A‐673 and TC‐71 cells and human pancreas adenocarcinoma‐derived AsPC‐1 cells as a control, in which DAX1 protein was not detected in Western blotting (data not shown), were treated with K‐234 at various concentrations, and cell viability was determined (Figure 2A). Here, NR0B1 is linked to pancreatic adenocarcinoma.
