Role of Intracellular and Extracellular Annexin A1 in MIA PaCa-2 Spheroids Formation and Drug Sensitivity.

ABSTRACT: Among solid tumors, pancreatic cancer (PC) remains a leading cause of death. In PC, the protein ANXA1 has been identified as an oncogenic factor acting in an autocrine/paracrine way, and also as a component of tumor-deriving extracellular vesicles. Here, we proposed the experimental protocol to obtain spheroids from the two cell lines, wild-type (WT) and Annexin A1 (ANXA1) knock-out (KO) MIA PaCa-2, this last previously obtained through CRISPR/Cas9 genome editing system. The use of three-dimensional (3D) models, like spheroids, can be useful to mimic tumor characteristics and for preclinical chemo-sensitivity studies. By using PC spheroids, we have assessed the activity of intracellular and extracellular ANXA1. Indeed, we have proved that the intracellular protein influences in vitro tumor
