My main line of research is the study of the influence of redox modulators in cancer. I am actively interested in understanding the influence of cellular redox pathways in different features of cancer cells, including proliferation, motility and invasiveness. These studies could contribute to the comprehension of the redox biology of cancer and to the development of novel therapeutic strategies. In this regard, I have been particularly interested in Superoxide dismutase mimics (SODm) and in studying the potential use of these compounds as anticancer drugs for breast and renal cancer therapy. Although these compounds are in clinical trials for certain cancer types, only very scarce information is available regarding their potential impact in metastases-related processes, namely in cell migration and invasion. In addition, I am also interested in exploring the anti-metastatic properties of food bioactive compounds (eg, thymoquinone or erucin).
