Mehdi Mollapour (born June 14, 1973) is a British-American Biochemist and Cancer Biologist. He is a Professor, Vice Chair for Translational Research and Director of Renal Cancer Biology Program for the Department of Urology, and Adjunct Professor at the Department of Biochemistry and Molecular Biology at SUNY Upstate Medical University.[1][2]

Education

Mollapour holds a BSc (Hons) in Microbiology and Biochemistry from the University of East London, MSc in Applied Molecular Biology of Infectious Diseases and Diploma in Tropical Medicine & Infectious Diseases from the London School of Hygiene & Tropical Medicine. In 2001 he received his PhD in Biochemistry from the University College London.[1]

Academic career

Mollapour completed his postdoctoral research at the University of Sheffield and in 2006 he received the Federation of European Societies (FEBS) fellowship.[1]

He joined the laboratory of Dr Len Neckers in Urological Oncology Branch, (Chief Dr. W. Marston Linehan), at the National Cancer Institute as a research fellow in 2007.[2]

In 2013 he joined the Department of Urology at the Upstate Medical University as an Assistant Professor. He became the Director of the Kidney Cancer Program within the same department in 2015.[1]

In 2018 he became the Professor of Urology and Adjunct Professor of Biochemistry and Molecular Biology at SUNY Upstate Medical University. He was also named the Vice Chair for Translational Research for the Department of Urology in the same year.[2] In 2023, Mollapour was elected the president-elect for the Cell Stress Society International; his term at president will begin in 2025.[3] Mollapour’s h-index is 45, based on 7,751 citations.[4]

Research

Molecular Chaperones

Mollapour is widely recognized for his research on post-translation regulation of the molecular chaperone Heat shock protein-90 (Hsp90)[5][6] and co-chaperones in cancer. His work demonstrated how reversible biochemical reactions can become directional and ordered, and in general, how a house-keeping machine (Hsp90) can be modulated through signaling inputs. Mollapour’s finding on post-translational modifications of the Hsp90 chaperone machinery has also explained the reasons for tumors sensitivity and selectivity towards the Hsp90 inhibitors. [7][6]

Tuberous Sclerosis Complex and Birt–Hogg–Dubé syndrome (BHD)

Mollapour’s laboratory has discovered the tumor suppressor TSC1 and FNIPs function as the new co-chaperones of Hsp90.[8][9][10][11] These two proteins are involved in Tuberous Sclerosis Complex and Birt–Hogg–Dubé syndrome (BHD) syndromes respectively. His research has identified a cross-talk between these two co-chaperones and demonstrated interconnectivity and compensatory mechanisms between the BHD and TSC pathways.[6]

Kidney Cancer

Mutations and loss of function of the Von Hippel-Lindau (VHL) tumor suppressor gene play a causal role in the pathogenesis of clear cell renal carcinomas (ccRCC), a pathological subtype that accounts for the majority kidney cancer each year. Mollapour work has shown that VHL ubiquitinates protein phosphatase-5 (PP5) for proteasomal degradation in a hypoxia- and prolyl-hydroxylation-independent manner. VHL-deficient ccRCC cell lines and patient tumors exhibit elevated PP5 levels. Downregulation of PP5 causes activation of the extrinsic apoptotic pathway in ccRCC cells, suggesting a prosurvival role for PP5 in kidney cancer.[12][13]

Mollapour’s research group has been supported by grants from the National Institutes for General Medical Science and the National Cancer Institute to design and examine novel therapeutic strategies for patients with kidney, bladder and breast cancer.

Metabolism and the Warburg Effect

Aerobic glycolysis in cancer cells, also known as the “Warburg effect”, is driven by hyperactivity of lactate dehydrogenase-A (LDHA). Mollapour’s team has identified the human tumor suppressor folliculin (FLCN) as a binding partner and uncompetitive inhibitor of LDHA. Their work has provided a new paradigm for the regulation of glycolysis. Cancer cells that experience the Warburg effect show FLCN dissociation from LDHA. Mollapour’s lab has shown that treatment of these cancer cells with a decapeptide derived from the FLCN loop region caused cell death, therefore providing a new avenue for targeted therapy in these cancers.[14][15]
