#3320 TGF-β increase caspase activation and migration in typical bronchial carcinoids

Introduction: Typical bronchial carcinoids (TBC) are well-differentiated neuroendocrine neoplasms (NEN) whose management can still be very challenging due to reduced sensitivity to therapy. Previous studies have reported TGF-β’s ability to activate mTOR pathway and induce epithelial to mesenchymal transition (EMT). Moreover, preliminary results show an overexpression of TGF-β signalling and caspase activation in TBC.

#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.

#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.

#986 Expression of the Truncated Somatostatin Receptor Variant Sstr5TMD4 in Medullary Thyroid Carcinoma

Introduction: Medullary thyroid carcinoma (MTC) is a rare tumor originating from thyroid parafollicular C cell. The only available treatment is surgical resection, which is not always feasible. Somatostatin and its receptors are expressed both in normal human thyroid C cells and in MTC, but their role has not been fully elucidated. The discovery of a truncated isoform of Sstr5, Sstr5TMD4, associated with increased invasiveness and aggressiveness in breast cancer, has opened new insight in the role of Sstr in cancers.
