Tissue-specific expression of the transcriptionally regulated serum and glucocorticoid-inducible protein kinase (Sgk) during mouse embryogenesis.
In situ hybridization of mouse embryo whole mounts and sagittal sections revealed a tissue- and stage-specific expression pattern of the transcriptionally regulated serum and glucocorticoid-inducible protein kinase (sgk) during embryogenesis. Sgk expression is first observed at embryonic day 8.5 (E8.5) in the decidua and yolk sac, and then during developmental stages E9.5 through E12.5 this kinase is highly localized in the heart chamber, otic vesicle, blood vessels surrounding the somites, and lung buds. At the later stages of mouse embryogenesis, E13.5 through E16.5, sgk expression becomes highly concentrated in brain (choroid plexus), distal epithelium and the terminal bronchi/bronchioles, adrenal gland, liver, thymus and intestines, remains high in heart tissue, and is expressed at a low level in the other embryonic tissues.
