Mathew Lab

Paul Mathew in his labThe Mathew laboratory is focused on the investigation of epithelial-stromal interactions that drive the metastatic progression of human malignancies and the development of novel therapeutics that target these mechanisms. Our major focus has been on prostate cancer and its progression to the highly-conserved phenotype of bone metastases. Our laboratory at Tufts Medical Center has identified a seed-and-soil mechanism involving integrin cooperativity in tumor-stromal interactions of prostate cancer and developed a proprietary bispecific antibody to target this cooperative biology (Joshi Cell Adh Migr 2016, Joshi et al, AACR 2018). We have traced survival pathways mediated by integrins in prostate cancer cells to the BCL-XL protein and have defined synthetic lethality in PTEN-deficient prostate cancer cells with the combination of PI3K/AKT and BCL-XL inhibition (Ren et al, MCR 2016; Ren et al, AACR 2018).  Our long-term goal is to translate these advances to the clinic in prostate cancer and other malignancies which share this thematic biology. 

Prostate cancer and bone metastases; integrin cooperativity in epithelial-stromal interactions; synthetic lethality in PTEN-deficient prostate cancer; clinical translation of experimental therapeutics in prostate cancer.  

Paul Mathew, MD is a hematologist/oncologist at Tufts Medical Center.Paul Mathew, MD is a faculty member in the Department of Hematology-Oncology at Tufts Medical Center from 2009-present. He is principally responsible for clinical care of all genitourinary malignancies (prostate, kidney, testis, penile and bladder cancer) and experimental therapeutics in these tumors at Tufts Medical Center. Dr Mathew completed his Internal Medicine Residency at Cook County Hospital, Chicago IL and Hematology-Oncology Fellowship at Mayo Clinic, Rochester MN. His prior faculty position was in the Division of Genitourinary Medical Oncology at MD Anderson Cancer Center, Houston, 2001-2009.
