Figure 4

Schematic representation of potential retinoic acid (RA) inhibition-related adverse outcome pathway (AOP). Inhibition of retinaldehyde dehydrogenase (RALDH) by known or unknown inhibitors potentially induces decreased cytosolic retinoic acid (RA) levels, which in turn, changes target gene expression, leads to abnormal embryonic eye development at individual level, and finally results in population decline of teleosts.
