PPARA and Fanconi anemia: Next, we looked at four pathways typically associated with female development in zebrafish [43] (I: Fanconi anaemia, II: Wnt signalling, III: oocyte meiosis and IV: progesterone-mediated oocyte maturation), as well as four pathways typically associated with male development (V: PPAR signalling, VI: p53 signalling, VII: cytokine–cytokine interaction and VIII: cardiac muscle contraction) [43].
