#1877 TSC22D1 Expression and Association with Clinic-Pathological Features in Bronchial Carcinoids
Introduction: Bronchial carcinoids (BC), typical (TC) or atypical (AC), are rare neoplasms arising from neuroendocrine cells spread in the respiratory epithelium Microarray data analysis obtained comparing a pool of TC with a pool of AC samples showed TSC22D1 down-regulation in AC samples. The role of TSC22D1 in neuroendocrine tumors is unknown.

#1999 Study of Cell Cycle Protein Expression Pattern in Bronchial Carcinoids: A New Potential Target for Medical Therapy?
Introduction: Bronchial Carcinoids (BCs) are rare neuroendocrine neoplasms arising from respiratory epithelium. The only effective treatment option is surgery, but its efficacy is frequently limited by metastatic spread. Everolimus prolongs progression free survival but patients may develop resistance. Previous studies demonstrated that Everolimus reduces viability of NCI-H720 cells (Atypical Carcinoid) but not of NCI-H727 cells (Typical Carcinoid). Everolimus decreases Ciclyn D1 protein levels in both cell lines but NCI-H727 cells survive, indicating a derangement in cell cycle control.

#2983 Differential TGF-β Signalling in Typical and Atypical Bronchial Carcinoids
Introduction: Typical and atypical bronchial carcinoids (TBC and ABC) are well-differentiated neuroendocrine neoplasms (NEN). Metastatic BC having low to moderate mitotic count may still be treated with somatostatin analogues and mTOR inhibitors; however, TBC and ABC have been reported to respond very differently to therapy and an effective treatment algorithm is still lacking. TGF-β is known for its ability to activate mTOR pathway and induce epithelial mesenchymal transition, affecting cell pathophysiological capabilities such as proliferation, migration and tissue invasiveness.

#173 Temozolomide in Metastatic Bronchial Carcinoids
Introduction: Metastatic bronchial carcinoids are rare neoplasms, where efforts of medical treatment thus far have been disappointing. Temozolomide has, however, shown some activity in a small prior study.

#462 Genome-Wide Expression Profiling Reveals Downregulation of OTP and CD44 and Upregulation of RET as Indicators of Poor Prognosis in Lung Carcinoids
Introduction: Lung carcinoids comprise a heterogeneous group of neuroendocrine tumors. Only few parameters have been identified that correlated with poor disease outcome, including 11q22-q25 deletions. New biomarkers are required to further improve diagnosis and prediction of prognosis.

#212 Reduced MEN1 Gene Expression in Pulmonary Carcinoids Is Associated With Metastatic Disease
Introduction: Lung carcinoids are neuroendocrine tumors that can be classified as typical (TC) or atypical (AC) carcinoids. Previously, MEN-1 mutations and associated LOH of 11q13 have been implied in tumorigenesis.

#1301 Role of TSC22D1 (TGFβ-Stimulated Clone 22 Domain Family Member 1) in Bronchial Carcinoids
Introduction: Neuroendocrine tumors (NETs) include bronchial carcinoids, either typical (TC) or atypical (AC). Tsc22d1 encodes for a member of TSC22 domain family of leucine zipper transcription factors; the protein (TSC22D1) is stimulated by TGFβ. Microarray data analysis obtained comparing a pool of TC tissue specimens with a pool of AC tissue specimens shows TSC22D1 down-regulation in AC samples. These data were confirmed by real time PCR and Western blot in vitro models of TC (NCI-H727 cells) and AC (NCI-H720 cells)

#360 High Resolution (Epi)genomic Analysis Comparing Pulmonary Carcinoids with a Favorable and a Poor Disease Outcome
Introduction: Lung carcinoids are a heterogenous group of neuroendocrine tumors. MEN1 mutations and 11q22-q25 deletions have been implied in their tumorigenesis. Very few genome wide and methylation studies have been conducted to further elucidate molecular mechanisms underlying tumorigenesis.
