Zebrafish and are paralogous members of the bromodomain-ET (BET) family of transcriptional coregulators that show structural and expression divergence-8

S through ovaries are shown in E-J. maternal RNAs are dispersed and abundant in stage I and II oocytes (A, E), and are sometimes found inside the germinal vesicle (gv), as in G (see small oocytes at far right). By stage III,transcripts accumulate around the outside of the germinal vesicle and rather unevenly around the periphery of the cortex just inside the vitelline envelope (C, E; G, arrowheads). RNAs then localize around the periphery of the cortex by late stage III, early stage IV (I, arrowheads). RNAs are also present in follicle cells of stage III/IV oocytes (C; G, I, arrowheads outside oocyte). Although maternal transcripts are also dispersed throughout stage I and II oocytes, and often found inside the germinal vesicle (B, F, H, J), in contrast to , they become strictly localized to the region surrounding the micropyle (D, mp; H, J, arrowheads), the future animal pole, sometime during stage III, and are not expressed in follicle cells. A,B: 40X; C-F: 80X; G-J, 100X.<p><b>Copyright information:</b></p><p>Taken from "Zebrafish and are paralogous members of the bromodomain-ET (BET) family of transcriptional coregulators that show structural and expression divergence"</p><p>http://www.biomedcentral.com/1471-213X/8/39</p><p>BMC Developmental Biology 2008;8():39-39.</p><p>Published online 10 Apr 2008</p><p>PMCID:PMC2373290.</p><p>
