Previous research experiences From the beginning of her research career Dr. Barletta has focused her attention on exploring the molecular mechanisms of cell adhesion and cell differentiation induced by specific adhesive substratum in normal and tumor cells. Her studies were centered on adhesive interactions between specific cell-surface molecules such as gangliosides, integrins, and heparan sulfates with adhesive proteins such as fibronectin, vitronectin and platelet factor 4 (PF4). Moreover, she focused her attention on the relationship between cell differentiation and invasive potential through extracellular matrix components. For this purpose she studied the effect of differentiating agents such as retinoic acid, platelet activatin factor (PAF), and neurotrophins CNTF (Ciliary Neurotrophic Factor) and BDNF (Brain Derived Neurotophic Factor) on differentiation and invasiveness of neuroblastoma cells through reconstituted membranes (Matrigel). In the last few years, Dr. Barletta has explored the molecular mechanisms of endothelial cell differentiation process. Indeed, endothelial differentiation requires modulation of adhesive properties and secretion of extracellular matrix degrading enzymes such as urokinase plasminogen activator (uPA). In this study she has revealed that basic fibroblastic growth factor (bFGF) upregulates uPA gene expression and that this effect is mediated by poly(ADP-ribose) polymerase (PARP) through activation of a mitogen-activated protein kinase pathway . Dr. Barletta during her research career has studied the role of mutationally activated ras oncogenes and occupational exposure in human acute myeloid leukemia (AML). In particular, she found in 111 AML cases a positive association between a priori at risk jobs and ras mutations.
