Figure 4. Biochemical and transcriptional response of skin to KrasG12D.
(A) Immunoblot analysis of phosphorylated downstream effector proteins (green) in wildtype and KrasG12D P4 skin. Samples show no significant change after normalized with total ERK (red), which also serves as a loading control. (B) Densitometry analysis of phosphorylated p90RSK, AKT, and ERK normalized to total ERK show no significant change of whole skin at baseline
