Focus

Functional Precision Medicine, Cancer Stem Cells, Therapy Resistance and Metastasis

Biography

Diana Azzam, PhD, is an Assistant Professor at Florida International University. She has a Masters in Biochemistry from the American University of Beirut, Lebanon and a PhD in Biochemistry & Molecular Biology from the University of Miami, Florida. Her lab focuses on implementing functional precision medicine (FPM) approaches in adult and pediatric cancer patients that have run out of treatment options.

Working with local hospitals including Nicklaus Children's Hospital and Cleveland Clinic Florida, her lab delivers individualized treatment plans based on a patient’s cancer genomic profile and ex vivo drug response. She is currently engaged in two clinical studies to assess feasibility and clinical utility of FPM in relapsed/refractory patients with childhood cancer (ClinicalTrials.gov registration: NCT05857969) and adult cancer (ClinicalTrials.gov registration: NCT06024603).

Dr. Azzam is working on setting up the first CLIA-certified lab in the State of Florida dedicated for functional cancer drug testing. Her goal is to launch large-scale prospective multi-center randomized clinical trials to better assess efficacy of FPM approaches in the treatment of refractory/relapsed cancers. In parallel, she is working on utilizing FPM as a tool to reduce health disparities in childhood cancer patients from minority populations. She is also integrating a novel machine learning approach to identify specific biomarkers among minority populations that can be targeted using FDA-approved drugs. Her lab also investigates cancer stem cells and how they may result from chronic environmental exposures to toxic metals such as arsenic.

The Conversation: Arsenic contamination of food and water is a global public health concern – researchers are studying how it causes cancer

Piece written by Diana Azzam, assistant professor of environmental health sciences at FIU and Cristina Andrade-Feraud, Ph.D. candidate in environmental health sciences at FIU.

FIU News: FIU awarded more than $77M in new state funding

The advocacy of former state Senator Anitere Flores and current state Representative Bryan Avila, chair of House Health Care Appropriations Subcommittee, helped Dr. Diana Azzam and her team receive $2 million in state appropriations. These funds will be used to acquire state-of-the-art robotic instrumentation that will greatly increase the speed and efficiency with which Azzam and her team identify personalized treatment options, allowing more patients to be helped every day.

FIU News: Neuroinflammation protein linked to worse survival in men with glioblastoma

Scientists have discovered a new link that could bring the scientific and medical community closer to understanding why glioblastoma, the most common malignant brain tumor, is deadlier in males. Listen on The Academic Minute.

FIU News: Collaborative brain cancer research contributes to hopes for new treatments, cure

An FIU-led study has revealed a correlation between the presence of a protein variant and poor survival in males suffering from the deadliest form of brain cancer.

FIU News: FIU and Cleveland Clinic Florida to collaborate on personalized cancer treatment research

Diana Azzam, a researcher in the Robert Stempel College of Public Health & Social Work, will collaborate with Cleveland Clinic Florida on a study to find new treatment options for cancer patients.

Lab

The Azzam Lab tackles advanced cancers through the usage of functional precision medicine in cancer treatment as well as a multifaceted study of cancer stem cells, the cells responsible for cancer relapse and metastasis.

Projects in the lab include the implementation of functional precision medicine to identify individualized treatment options for advanced pediatric and adult cancers, examination of the impact of environmental toxins on cancer stem cell formation, and role of neuroinflammatory protein TSPO in glioblastoma stem cells
