Fig. 6. Xlim1 is regulated by miR-30a-5p. (A-D′) Whole-mount in situ hybridization for Pax2 (A,A′), Pax8 (B,B′), Hnf1-β (C,C′) and Xlim1 (D,D′), comparing uninjected and miR-30a5p-MO-injected Xenopus embryos at stage 39. (E-G′) Whole-mount in situ hybridization for Xlim1 mRNA of uninjected and miR-30a5p-MO-injected Xenopus embryos at stages 31, 35 and 39. Note that Xlim1 expression is maintained at a higher level in miR-30a5p-MO-injected embryos after stage 35, when endogenous expression of miR-30a-5p can first be detected (arrows in D′,G′). (H,H′) Immunohistochemistry with 4A6 of stage 40 embryos injected with 4 pg pCS2-Lhx1* DNA into one blastomere at the 4-cell stage, comparing the left with the right side. Arrows indicate changes in 4A6 staining. Ectopic expression of Lhx1 mRNA transcribed from the pCS2-Lhx1* was confirmed by in situ hybridization (data not shown). |
