Electron paramagnetic resonance (EPR) examination of hepatic microsomes from differently pretreated animals has lead to the conclusion that MC pretreatment leads to the formation of cytochrome P-1+50 (P-1+1+8) with high spin iron (6, 1+6). Chevion et al. (28) failed to demonstrate the presence of high spin cytochrome P-1+50 in a teleost fish even after induction with MC. The work of Chevion et al. (28 ) indicates further that the fish cytochrome P-1+50, which is inducible with PAH s and metabolizes readily PAH s, is not identical with the mammalian cytochrome P-1+1+8.

Since this structure was first proposed, Braunitzer and co-workers have determined the amino acid sequence of rhinoceros hemoglobin (23a). Its allosteric effector site shows only a single substitution compared to that of human hemoglobin—His NA2/8 — Glu—yet ATP lowers its oxygen affinity more than DPG, and GTP lowers it more than ATP, just as in teleost fish (R. Baumann, unpublished observations). This observation supports the hydrogen bond between N-6 of the adenine and Glu NA2 proposed in Fig. 6 in fact it can hardly be explained without that bond.

Figure 7 shows the effect of ectopic administration of T3 to the developing zebrafish embryo. At nontoxic concentration (50 nM), only a moderate fraction (less than 5%) of the zebrafish transcriptome shows significant changes. Ossification, visual processes, and the hematopoietic system were the physiological processes most affected by the treatment, in a pattern consistent with an advancement of the development in these particular functions (Fig. 7b). Genes involved in these three processes are known targets for TDCs during metamorphosis in amphibians, teleost fishes, and lampreys [54—60], and constitute molecular counterparts of different endpoints used to test for TDC in amphibians [56, 58]. Therefore, they are excellent candidates for markers of thyroid disruptors in zebrafish at early developmental stages. Chapter 14 provides a more in-deep description of the developmental effects of thyroid disruption in zebrafish embryos.

Studies on teleost fish and mammals have demonstrated the existence of non-rod, non-cone ocular photoreceptors. In the case of VA opsin in the roach, electrophysiological evidence suggests that one function of this photosensory photopigment is to modulate the activity of retinal horizontal cells. To what end remains unclear, but this fits with the general role of horizontal cells in the teleost...
