CD200 Expression in Neuroendocrine Neoplasms
Objectives CD200 expression has been well studied in hematopoietic malignancies; however, CD200 expression has not been well-characterized in neuroendocrine neoplasms. We examined CD200 expression in 391 neuroendocrine neoplasms from various anatomic sites. Methods Tissue blocks containing pulmonary small cell carcinoma, pulmonary carcinoid, large cell neuroendocrine carcinoma, pancreatic neu...
متن کاملTargeting the mTOR pathway in neuroendocrine tumors.
Neuroendocrine tumors (NETs) are rare, generally indolent tumors that are lethal in the metastatic setting. Treatment options to control tumor growth are limited. In clinical trials, investigational oral mammalian target of rapamycin (mTOR) inhibitors have shown activity in patients with metastatic NETs. The purpose of this article is to provide oncology nurses with a background on the mechanis...
متن کاملTargeting the mTOR Signaling Pathway in Neuroendocrine Tumors
OPINION STATEMENT Neuroendocrine tumors (NETs) are a heterogeneous group of malignancies characterized by variable but most often indolent biologic behavior. Well-differentiated NETs can be broadly classified as either carcinoid or pancreatic NET. Although they have similar characteristics on routine histologic evaluation, the 2 tumor subtypes have different biology and respond differently to t...
متن کاملExpression of Reg IV and Hath1 in neuroendocrine neoplasms.
Reg IV (RELP), a Regenerating protein family member, is constitutively expressed in neuroendocrine cells of the intestinal mucosa. The helix-loop-helix transcription factor Hath1 is the human homologue of murine Math1, which regulates the embryonic differentiation of neural and intestinal secretory lineage cells. Hath1 is constitutively expressed in a subset of mature secretory gastrointestinal...
متن کاملmTOR and P70 S6 kinase expression in primary liver neoplasms.
PURPOSE mTOR and P70 S6 kinase (S6K) play a key role in regulating protein translation. The role of mTOR and S6K in hepatocellular carcinoma has not been investigated, but this pathway is of particular interest because an effective inhibitor, rapamycin, is available. This study was undertaken to determine the prevalence and clinicopathological correlates of mTOR pathway activation in hepatocell...
