EXOSOMES DERIVED FROM METASTATIC COLON CANCER CELLS TRANSFER MALIGNANT PHENOTYPIC TRAITS TO SURROUNDING CELLS: THEIR EMERGING ROLE IN TUMOR HETEROGENEITY

Several studies have clearly demonstrated that within a heterogeneous tumor mass the inter-clonal cooperation between metastatic and non-metastatic cells can facilitate the tumor progression. Recent accumulating evidence has highlighted that tumor-derived exosomes (TDEs) play a relevant role as mediator of the inter-clonal collaborative cooperation affecting the properties of both tumor and non-tumor component. In this context, our goal was to understand if exosomes derived from highly metastatic cells may influence the behaviour of less aggressive tumor cells and the properties of endothelium. We found that metastatic SW620 cells transfer through exosomes (SW620Exos) their round/amoeboid p…

SWATH-MS reveals a key role for IPO7 in the molecular mechanism underlying antitumor effects of curcumin on Chronic Myelogenous Leukemia cells

Imatinib represents the elective drug for the treatment of patients with Chronic Myelogenous Leukemia (CML). However, albeit it is effective in controlling CML and preventing progression to blast crisis (BC), it is not curative. Therefore, it is mandatory to find novel therapeutic combinations to completely eradicate CML. It was described that CML cells expressing higher level of BCR-ABL show an increased glucose metabolism (termed aerobic glycolysis or Warburg effect) correlated with a non-hypoxic induction of HIF-1α, factor implicated in leukemia stem cells (LSCs) maintenance[1,2]. In the present study, we demonstrated that curcumin, an Indian spice with multiple anticancer properties, is…
