Alessio Giubellino

Associate Professor


Dr. Giubellino is a board-certified anatomic pathologist and dermatopathologist with a strong research background in cellular/tissue biology and translational research. As a physician-scientist he contributed to the advancement of several basic science, translational and clinical research projects, lately with a particular focus on melanocytic lesions and other dermatologic diseases. He has employed different molecular and cellular techniques and immunohistochemical analysis of tissue samples to bridge basic science and clinical medicine.

One of Dr. Giubellino chief interests has been the investigation and development of biomarkers for cancer diagnosis, as well as for prognostic and predictive purposes. This interest stems from prior work on receptor tyrosine kinases (RTKs) and receptor-mediated downstream signaling molecules in tumor progression. During his work at the National Institutes of Health (NIH), Dr. Giubellino has contributed to defining the proto-oncogene MET, the tyrosine kinase receptor for the hepatocyte growth factor (HGF), as a cancer biomarker, he has developed xenograft mouse models of tumor progression and discovered novel therapeutic approaches, including targeting adaptor proteins, like GRB2, in the downstream signaling of RTKs, for a variety of neoplasms.

Given the concurrent role of MET in the modulation of the immune response and the interplay with immune checkpoints in other malignancies, Dr. Giubellino investigated the expression pattern of MET and the immune checkpoint PD-L1, a relevant target for immunotherapy, and found that these two surface receptors follow a similar expression pattern in metastatic melanoma (and not in primary melanoma) and published this observation in the journal Cancers (2020). Additional studies are currently underway to understand this relationship.

More recently Dr. Giubellino has been involved in several studies using the relatively new technology of Spatial Transcriptomics and Spatial Proteomics, techniques that allow the precise localization of multiple mRNAs and proteins in a morphologic context in tissue samples.

Moreover, Dr. Giubellino research group is exploring the use of digital pathology and artificial intelligence to enhance diagnostic and prognostic evaluation of clinical tissue samples. An example of this type of study has been published in Histopathology (2021) where his research group estimated precise melanoma tumor burden by digital cell counting in sentinel lymph nodes on whole slide images (WSI) using an open-source software for digital pathology.

Giubellino thinks this comprehensive approach will reveal relevant biomarkers to help clinicians to improve the life and management of patients visiting our Clinics and Health System.
