  • Understanding pancreatic carcinogenesis

    Pancreatic carcinogenesis is well defined as a multistage process accompanied by distinct morphological and histological changes, resulting from molecular alterations that are acquired during malignant transformation. However the functional impact of many of the deregulated molecules remains to be elucidated. We have recently shown the contribution of DYRK1A to pancreatic tumor progression by stabilization of the receptor tyrosine kinase c-MET. Currently, we are investigating other DYRK1A- dependent mechanisms that may signal to amplify its pro-tumorigenic role.

  • Oncolytic virotherapies against pancreatic cancer

    Oncolytic adenoviruses replicate in the tumors leading to oncolysis and triggering an immune cell infiltration into the tumor that results in an antitumor response. We have developed oncolytic adenovirus designs that present high selectivity for pancreatic tumors and improved tumor replication, and shown its anti-cancer activity in patient-derived xenografts (PDX). We are now particularly interested in manipulating the viruses to permit efficient intravascular delivery, intratumor spread and engaging of the host immune system to generate more efficacious therapies for primary and metastatic tumors. We use a combination of PDX mouse models and an organoid platform to screen for the optimal designs.

  • Preclinical gene therapy /genome editing studies for metabolic rare diseases

    Glutaric aciduria type I (GA-I) is a metabolic inherited disease due to mutations in the GCDH gene. Individuals with GA-I are controlled by a dietary treatment. However, deficits in adherence to the treatment or lack of effectiveness in some patients result with a negative impact on the clinical outcome.  We are developing adeno-associated viral vectors (AAV) and explore the feasibility of an AAV-gene therapy approach in mouse models of GCDH deficiency. The results from this project may provide novel treatment options for GA-I.
