Molecular Characterization of the Blood-Brain Barrier in DR6 and TROY Knockout Embryos, Related to Figure 7

(A) Immunohistochemical analysis of pericyte coverage (PDGFRbeta), barrier maturation (PLVAP), and tight junction morphology (ZO-1 and CLAUDIN-5) of CNS vasculature (BSL: FITC-lectin) in DR6 and TROY knockout E15.5 embryonic mouse cortices. No gross mislocalization or expression level differences could be detected in DR6.KO, DR6flox/flox;Tie2-Cre, and TROY.KO embryos when compared to littermate controls. Results representative of at least three independent experiments are shown. (B) Immunoblot analysis of pericyte coverage (PDGFRbeta), glucose transporter 1 expression (GLUT1), and tight junction expression (ZO-1 and CLAUDIN-5) in DR6, TROY, and DR6flox/flox;Tie2-Cre (DR6.cko) conditional knockout E15.5 embryonic mouse cortices. While no significant PDGFRbeta, GLUT1, or CLAUDIN-5 expression level changes could be detected in DR6.KO, DR6flox/flox;Tie2-Cre, and TROY.KO embryos when compared to littermate controls, ZO-1 levels were significantly reduced in DR6flox/flox;Tie2-Cre embryos, and trending towards reduction in DR6.KO and TROY.KO embryos. Relative protein levels were calculated by normalization to actin loading control levels. Data are presented as the mean ± SEM (*p < 0.05).
