Role of TSC22D1 (TGFβ-Stimulated Clone 22 Domain Family Member 1) in Bronchial Carcinoids Abstract #1301

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)
Aim(s): To evaluate the influence of TSC22D1 on cell proliferation, cell viability and apoptosis in NCI-H727 cell line
Materials and methods: TSC22D1 was silenced by shRNA in NCI-H727 cell line to obtain a stable clone (shTSC22D1-NCI-H727). NCI-H727 and shTSC22D1-NCI-H727 cells were treated with TGFβ. Cell viability, caspase activation and cell proliferation were evaluated in both cell lines

#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.

#1090 p27kip1 Is Involved in the Resistance of Human Bronchial Carcinoids to m-TOR Inhibitors
Introduction: Bronchial carcinoids (BC) are still orphan of medical therapy. We previously demonstrated that the typical BC human cell line NCI-H727 is sensitive to Everolimus (E), in terms of cell viability reduction, with a G0 cell-cycle arrest, while the atypical human BC cell line NCI-H720 is not. The mechanisms underlying this phenomenon have not been clarified

#1494 CDK-Inhibitors as New Therapeutic Treatment for Human Bronchial Carcinoids
Introduction: Bronchial Carcinoids (BC) are still orphan of medical therapy. We previously demonstrated that 70% of primary BC cultures are sensitive to Everolimus (E), an mTOR inhibitor, while 30% are not. We also observed that in 2 human BC cell lines, the NCI-H720 (sensitive to E) and NCI-H727 (resistant to E), mTOR resistance may be linked to a differential cell cycle protein expression (CyclinD1/E, CDK2/4, p27kip1/p27kip1phospho-Ser10), which is higher in BC resistant to E as compared to sensitive ones, suggesting an impaired p27 function

#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.

#3015 Biopsy Specimen Diagnosis in Pulmonary Carcinoids, A Shot in the Dark
Introduction: Pulmonary carcinoids (PCs) are rare well-differentiated neuroendocrine tumors, which can be separated into typical carcinoid (TC) and atypical carcinoid (AC). Advised treatment for local carcinoid disease is surgical resection using lobectomy, while parenchymal saving strategies such as sub-lobar or endobronchial resection might be considered for TC. In general, pre-operative diagnosis using a (transbronchial/transthoracic) biopsy sample is performed to demonstrate malignancy. However, TC and AC classification can solely be performed on surgical resection specimens, which may challenge pre-operative treatment decisions.
