Phosphorylated AMPK and p-MAPK3/1 expression in colorectal cancer. (A) Positive for p-AMPK cytoplasmic expression (arrowheads). (B) Negative for p-AMPK expression (white arrowheads). (C) Positive for p-MAPK3/1 nuclear expression (white arrows). (D) Negative for p-MAPK3/1 expression (block arrow). Stromal cells serve as an internal positive control for p-MAPK3/1 expression (arrow).
