Phosphorylated mTOR Expression Profiles in Human Normal and Carcinoma Tissues

Figure 4

Immunoexpression of p-mTOR in primary and metastatic carcinoma tissues (200x). (a) Primary clear cell renal cell carcinoma shows p-mTOR negativity, while (b) metastatic cancer in the lymph node of the same patient shows strong p-mTOR positivity. (c) Hepatocellular carcinoma shows patchy p-mTOR staining along the periphery of the tumor in the liver (arrows) and (d) metastatic cancer in the lymph node shows diffuse p-mTOR positivity.
