Quantitative changes of amphioxus CYP26 expression in response to retinoic acid (RA) signaling alterations. Expression of CYP26-1, CYP26-2, and CYP26-3 in amphioxus (Branchiostoma lanceolatum) was assessed by quantitative real time PCR (qPCR) at two developmental stages (mid neurula at 20 h of development and early larva at 48 h of development). RAR expression was also established and used as a normalized positive control. (a) Relative normalized expression (left panel) and fold change of expression levels (right panel) at the mid neurula stage, using a Log2 scale. (b) Relative normalized expression (left panel) and fold change of expression levels (right panel) at the early larval stage, using a Log2 scale
