Influence of Tumor Microenviroment in response modulation to treatment in human BP-NENs

Bresciani Giulia , Ditsiou Angeliki , Cilibrasi Chiara , Vella Viviana , Giamas Georgios , Zatelli Maria Chiara , Gagliano Teresa

Introduction: Broncho-Pulmonary Neoplasms (BP-NENs) are rare neoplasms arising from neuroendocrine cells of the respiratory epithelium. Since previous studies in our lab have demonstrated the efficacy ofEverolimus, approved for BP-NENs treatment, and Dinaciclib, a Cyclins and CdKs inhibitor, on monolayer system we have investigated if a more complex tumour system could generate a change in drugs effects and cell resistance. Therefore, through the use of 3D culture model, we ha...

Available 3D cultures methods: study on a Pancreatic Neuroendocrine Neoplasm cell line

Bresciani Giulia , Hofland Leo J , Giamas Georgios , Gagliano Teresa , Zatelli Maria Chiara

Background: Pancreatic Neuroendocrine Neoplasms (pNENs) are malignancies arising from the endocrine pancreas. Past in vitro studies have led to a better comprehension and characterization of this malignancy under several points of view. However, effective medical therapies are still not available, therefore, it is essential to continue studying this malignancy in order to identify a successful approach. Due to tumour complexity, techniques such as 3D cultures, able to...

Identification of molecular targets of Sunitinib in pancreatic neuroendocrine tumours

Bresciani Giulia , Gagliano Teresa , Hofland Leo J , Gentilin Erica , Falletta Simona , Riva Eleonora , Chiara Zatelli Maria

: Pancreatic neuroendocrine tumours (pNETs) are rare neoplasms arising from the endocrine pancreas. The fist line treatment is surgery that is often not curative in the presence of metastatic disease. Therefore, there is an increasing need for medical therapy. Sunitinib is a multi-target receptor tyrosine-kinase (RTK) inhibitor, described as having as main target VEGF receptor, with antitumor and antiangiogenic effects, approved for pNETs medical treatment. This study is aimed...

Study of different in vitro systems for the evalutation of Sunitinib effects in pancreatic neuroendocrine tumour cells

Bresciani Giulia , Gagliano Teresa , Hofland Leo J , Gentilin Erica , Falletta Simona , Riva Eleonora , Chiara Zatelli Maria

Finding new preclinical models to study the effects of anticancer drugs is one of the aims of biomedical research. Indeed, testing different in vitro systems can lead to a better understanding of the molecular pathways regulating tumor development and growth, and help to find new therapeutic approaches. This is crucial especially in the settings of pancreatic neuroendocrine tumours (pNET), where one of the main drugs approved for medical treatment is Sunitinib, a mult...

New horizons in medical treatment of Bronchial Carcinoids: evidence from in vitro models

Bresciani Giulia , Di Tullio Chiara , De Souza Patricia Borges , Zatelli Maria Chiara

Introduction: Bronchial Carcinoids are rare neoplasms originating from the diffuse neuroendrocrine system. Surgery is the only effective therapy but may not be feasible due to metastases. Available therapy may control symptoms but not tumor bulk. Everolimus has shown promising results, however patients may develop resistance. Previous studies demonstrated that Everolimus reduces viability of NCI-H720 (Atypical Carcinoid) but not of NCI-H727 cells (Typical Carcinoid). In order ...

EGFR and IGF1R affect Sunitinib activity: novel targets for Broncho-Pulmonary Neuroendocrine Neoplasm treatment

Bresciani Giulia , Ditsiou Angeliki , Cilibrasi Chiara , Vella Viviana , Rea Federico , Schiavon Marco , Cavallesco Narciso Giorgio , Giamas Georgios , Zatelli Maria Chiara , Gagliano Teresa

Background: Available medical treatments for Broncho-Pulmonary Neuroendocrine Neoplasm (BP-NENs) derived from clinical trials are not specific for the management of this malignancy. Sunitinib, a multi-receptor tyrosine-kinases (RTKs) inhibitor, mainly described as VEGFR inhibitor, has shown its efficacy in Pancreatic NENs but there are not available data about its action in BP-NENs. Our aim was to understand the effects of RTKs inhibition promoted by Sunitinib in order to eval...
