| abstractText | Runx3 is essential for normal vertebrate lung development and Runx3 knockout (KO) mice die within 24 h after birth because of various organ defects including defects in alveolar expansion. For proper early lung development, vasculogenesis and angiogenesis are necessary in humans. Previous studies have reported that various signaling molecules, such as CD31, VEGF and vWF, are closely related to lung vasculogenesis and angiogenesis. To confirm the relationship between Runx3-related lung defects and vasculogenesis, the localization of various blood vessel markers is examined in WT and Runx3 KO mouse lungs at PN1. Our results indicate that CD31, VEGF and vWF were dramatically up-regulated by a loss of Runx3 during lung development. Moreover, U0126, a MEK inhibitor, rescued the lung phenotype and vascularization by regulation of ERK signaling. Therefore, it was concluded that lung vasculogenesis and angiogenesis were induced in the Runx3 KO mouse, which shows lung defects, by increased CD31, VEGF and vWF. |
