Experiment details for nkx2-1

Rankin SA et al. (2012) Assay

Suppression of Bmp4 signaling by the zinc-finger repressors Osr1 and Osr2 is required for Wnt/β-catenin-mediated lung specification in Xenopus.

Fig. 4. FGF, Wnt/β-catenin and RA signaling regulate Xenopus lung development in a pathway with Osr1/Osr2. (A-D) Embryos were treated from stages 25-35 with DMSO vehicle (A), 100 μM PD173074 (B), 50 μM XAV939 (C) or 10 μM BMS493 (D), and assayed at stage 35 with the indicated probes. (E). Embryos were treated between stages 28 and 35 with vehicle (DMSO), 10 μM BIO, 80 μM SU5402, a combination of 80 μM SU5402 + 10 μM BIO, 10 μg/ml cycloheximide (CHX) or CHX +10 μM BIO, and analyzed for nkx2.1 at stage 35 and sftpc at stage 40. Black arrows indicate normal expression, red arrows indicate absent expression, yellow arrows indicate reduced expression and green arrows indicate expanded or rescued expression.

Fig. 5. Osr1/Osr2 act upstream of Wnt-mediated pulmonary specification and RA-regulated lung bud growth. (A-G) Osr1/Osr2-MO- and MM-MO-injected embryos were treated at stages 25-35 with DMSO vehicle, 10 μM BIO or 1 μM all-trans-retinoic acid (RA), and analyzed for nkx2.1, sox2, wnt2b and raldh2 at stage 35 (A-F) and sftpc at stage 42 (dorsal view) (G). Black arrows indicate normal expression, red arrows show absent expression, green arrows and lines indicate expanded expression and white arrows indicate rescued expression.
