Immunohistochemical staining in gastritis, gastric adenoma and carcinoma. Note mTOR positivity was strongly observed in the cytoplasm, while P70S6K in the cytoplasm and nucleus. mTOR expression was observed in non-cancerous mucosa (a, +++), adenoma (b, +++) and carcinoma(c, +++). P70S6K protein was immunoreactive in non-neoplastic mucosa (d, +++), adenoma (e, +++) and carcinoma (f, +++).
