- Evaluation of the estrogenic effects of UV filters on the sergeant major damselfish, Abudefduf saxatilis Mélina Soto Gabriela Rodríguez-Fuentes Ciencias de la Tierra sunscreen vitellogenin Abudefduf saxatilis Oxybenzone, octyl salicyla te, and octinoxate are compounds used in a variet y of products as a prot ection against exposure to ultraviolet radiation. Concerns have emerged regarding their envi ronmental safety as previous st udies have shown that they tend to bioaccumulate and act as potentia l xenoestrogens in aquatic orga nisms. To our knowledge no studies have investigated their impa ct on tropical reef-associated species. Thus, the aim of the present study was to evaluate the estrogenic effects of these three compounds on the abundant, reef-associated sergea nt major damselfish, Abudefduf saxatilis . As no genomic information of A. saxatilis was available, the first part of the study was to isolate and to sequ ence the vitellogenin (VTG) and -actin genes. In the second part, the potential estrogenicity of the three compounds in juvenile fish (<5 cm) was st udied using gene expression and protein synt hesis analyses to ev aluate the induction of VTG. Fish were exposed to doses of 5, 25, and 50 g g –1 of oxybenzone, octyl salicylate, oc tinoxate, and to a mixture of them in a similar proportion to the one used in commercial personal care products. An increment in alkali-labile phosphate was observe d in all treatments, but it w as only statistically significant in the positive control (17 -estradiol). Relative gene expression was only statistically augmented in the positive control. 2014 artículo científico 0185-3880 https://www.redalyc.org/articulo.oa?id=48032071003 en http://www.redalyc.org/revista.oa?id=480 Ciencias Marinas application/pdf Universidad Autónoma de Baja California Ciencias Marinas (México) Num.3 Vol.40
