Deciphering Gene Expression Program of MAP3K1 in Mouse Eyelid Morphogenesis. Mus musculus

Embryonic eyelid closure is a critical step of mammalian ocular surface development involving the forward movement and ultimate fusion of the upper and lower eyelids. Although its underlying mechanism of action is not fully understood, a functional mitogen-activated protein kinase kinase kinase 1 (MAP3K1) is essentially required for eyelid closure. We used microarray to characterize the central role that MAP3K1 plays in embryonic eyelid closure. Overall design: We used Laser Capture Microdissection (LCM) to obtain highly enriched eyelid leading edge and inner eyelid cells from E15.5 wild type and MAP3K1-deficient fetuses and analyze genome-wide expression profiles.
