Figure 3. miR-17-92 represses genes important for craniofacial development.
(A–D) Whole mount in situ hybridization with indicated probes in mouse embryos with designated genotypes. Black arrows and arrowhead designate expression pattern. (E) qRT-PCR data indicate that expression of Fgf10, Shox2, Tbx1, Tbx3 and Osr1 is elevated in miR-17-92; miR-106b-25 compound knock out mutants. (F) Overexpression of miR-17-92 in cranial neural crest results in repression of Fgf10, Shox2, Tbx1, Tbx3 and Osr1. (G) Luciferase reporter assays with Tbx3 reporters and miRs as labeled (See Fig. S5 for miR seed sites and mutations). mean ±s.e.m., * indicates statistically significant difference, Student's t-test (P<0.05).
