TNFSF14 and breast cancer: Notably, consistent with the findings observed in LIGHT‐ and IFNγ‐mediated apoptosis of MDA‐MB‐231 breast cancer cells 16, although extensive caspase activation of caspases‐3, ‐8 (data not shown) and ‐9, were observed, treatment with a broad range caspase inhibitor and a caspase‐3 inhibitor (data not shown) do not completely block LIGHT/IFNγ‐induced apoptosis in MIN6 cells.
