where the bone morphogenetic protein (BMP) pathway signaling is highly active. The researchers showed that BMP signaling makes neuroblastoma cells much more vulnerable to retinoic acid.

We know today that Wnt and a handful of other signalling systems (Notch, Hedgehog, TGFβ (transforming growth factor-β)–BMP (bone morphogenetic protein) and receptor tyrosine kinases ...
