Abstract
The AID/APOBECs are a group of zinc-dependent cytidine deaminases that catalyse the deamination of bases in nucleic acids, resulting in a cytidine to uridine transition. Secreted novel AID/APOBEC-like deaminases (SNADs), characterized by the presence of a signal peptide are unique among all of intracellular classical AID/APOBECs, which are the central part of antibody diversity and antiviral defense. To date, there is no available knowledge on SNADs including protein characterization, biochemical characteristics and catalytic activity. We used various in silico approaches to define the phylogeny of SNADs, their common structural features, and their potential structural variations in fish species. Our analysis provides strong evidence of the universal presence of SNAD1 proteins/transcripts in fish, in which expression commences after hatching and is highest in anatomical organs linked to the immune system. Moreover, we searched published fish data and identified previously, "uncharacterized proteins" and transcripts as SNAD1 sequences. Our review into immunological research suggests SNAD1 role in immune response to infection or immunization, and interactions with the intestinal microbiota. We also noted SNAD1 association with temperature acclimation, environmental pollution and sex-based expression differences, with females showing higher level. To validate in silico predictions we performed expression studies of several SNAD1 gene variants in carp, which revealed distinct patterns of responses under different conditions. Dual sensitivity to environmental and pathogenic stress highlights its importance in the fish and potentially enhancing thermotolerance and immune defense. Revealing the biological roles of SNADs represents an exciting new area of research related to the role of DNA and/or RNA editing in fish biology.

Abstract
Amisulbrom is an oomycete-specific fungicide that was developed by Nissan Chemical Industries Limited. The exposure of developing zebrafish embryo to amisulbrom caused disorders in the visual phototransduction system. However, the potential toxic mechanisms of amisulbrom on retinal development remains unclear. The research purpose of this study was to evaluate the adverse effects of amisulbrom on retinal development in a model organism, the zebrafish. Zebrafish embryos were treated with 0, 0.0075, 0.075, or 0.75 μM amisulbrom from 3 h post-fertilization (hpf) to 72 hpf. Compared with the control group, amisulbrom-treated zebrafish embryos displayed phenotypic microphthalmia, dysregulation of gene transcription levels (alcama, prox1a, sox2, vsx1, rho, bluops, rdops, uvops, and grops) related to the retinal cell layer differentiation, and increased retinal apoptosis. In addition, the content of glutathione and malondialdehyde increased significantly after exposure to amisulbrom. Overall, our data demonstrate the toxicity of amisulbrom to eye development, which will help to assess the potential ecotoxicological impacts posed by amisulbrom to aquatic species.
