Identification of candidate downstream targets of TGFβ signaling during palate development by genome-wide transcript profiling.

ABSTRACT: Nonsyndromic orofacial clefts are common birth defects whose etiology is influenced by complex genetic and environmental factors and gene-environment interactions. Although these risk factors are not yet fully elucidated, it is known that alterations in transforming growth factor-beta (TGFβ) signaling can cause craniofacial abnormalities, including cleft palate, in mammals. To elucidate the downstream targets of TGFβ signaling in palatogenesis, we analyzed the gene expression profiles of Tgfbr2(fl/fl) ;Wnt1-Cre mouse embryos with cleft palate and other craniofacial deformities resulting from the targeted inactivation of the Tgfbr2 gene in their cranial neural crest (CNC) cells. Relative to controls, palatal tissues obtained from Tgfbr2(fl/fl) ;Wnt1-Cre mouse embryos at embryonic day 14.5 (
