Figure Lengend Snippet: Figure 3. Western blot analysis of PKC and PI3Kα-AKT-mTOR pathway inhibition. Paired tumor biopsies were assessed by Western blot for pAKT, pS6, pERK1/2, pMARCKS, and the respective total proteins. GAPDH was used as a loading control. Clinical outcomes for these respective patients are listed. Protein quantitation of the pre-treatment (left) and post-treatment (right) Western blot analysis performed with Image J. The pre-treatment sample expression level represents a baseline of 100%, with the post-treatment sample expression levels relative to this baseline. Bar plots represent pAKT/total AKT, pS6/total S6, pERK1/2/ total ERK1/2, and pMARCKS/MARCKS, respectively.
