RARG and neuroblastoma: As HCB has been shown to affect c-SRC regulation after binding to the aryl hydrocarbon receptor (AhR) [30], it is possible that the effect of HCB on neurite outgrowth may be a consequence of an alteration in the binding of c-SRC to the neuronal inducer retinoic acid receptor gamma (RARγ) [17], as binding of c-SRC to RARγ has been reported to regulate neurite outgrowth in human neuroblastoma cells [31].
