Claúdio Maia is graduated in Biochemistry and PhD in Biomedicine. From 2009, he is Associated Professor and integrated researcher at Health Sciences Research Center (CICS-UBI). In addition, he is vice-coordinator of Hormones & Metabolism Group of CICS-UBI and is member of the body responsible for animal welfare (ORBEA) of UBI. As investigator, he has published 66 articles in peer-reviewed journals, and supervise(d)/co-supervise(d) 25 masters students and 10 PhD students. The main scientific focus includes to explore the cellular and molecular mechanisms underlying the male reproductive function and prostate cancer, as well as to evaluate the usefulness of novel biomarkers and to explore novel strategies of treatment. As know-how technical, it can be highlighted his expertise in cell culture and animal experiments, and in several assays to evaluate gene expression (qPCR, western blot, and immunohistochemistry), assays of cell viability, cell cycle, and apoptosis (MTS, Ki-67, Tunel, Caspase-3 activity, etc)Besides his role as professor and researcher, he was responsible to organize and implement a diagnostic test (qPCR) for COVID-19 in "Cova da Beira" region. Considering his expertise in molecular biology and his work as volunteer in Laboratory for COVID-19 diagnostic tests, he is at the moment the Principal Investigator of the project "CICS4COVID - Test, Track, and innovate in the diagnosis of COVID-19 (AAC 02/SAICT/2020, n.º 072541, ~300.000 euros)", funded by Fundo Europeu de Desenvolvimento Regional (FEDER) through the Programa Operacional Regional do Centro, and by Foundation for Science and Technology. Regarding his main focus of investigation, the ongoing projects intend to: i) characterize the role and regulation of Six Transmembrane Epithelial of the Prostate 1 (STEAP1) proteins in prostate cancer; ii) evaluate the usefulness of STEAP1 as a biomarker or putative therapeutic target; and iii)- explore novel approaches for the treatment of prostate cancer. Currently, he is member of the project "Structural Determination and Function Analysis of the STEAP1 Protein: Towards a New Target for Cancer Treatment Investigador", funded by Instruct-ERIC (PID: 11936).
