Aminopeptidase N (CD13): Bridging physiology, pathology and therapeutic potential
Gabriel C Nwokolo, Robert A Falconer, Francis M Barnieh (2025) Adv Clin Chem . 207-269.
Dr Francis Mprah Barnieh is a Wellcome Research Fellow and an early-career cancer pharmacologist at the University of Bradford. His research focuses on tumour hypoxia, the DNA damage response (DDR), and the development of tumour-selective therapies for aggressive and treatment-resistant cancers. His work integrates mechanistic biology with innovative drug development strategies to identify and exploit tumour-specific vulnerabilities.
He obtained a First-Class
Honours BSc in Biochemistry from the University of Ghana, followed by an MSc in
Cancer Pharmacology (Distinction) and a PhD in Cancer Drug Discovery & Pharmacology from the
University of Bradford. His doctoral research focused on the development of
protease-activated peptide prodrugs targeting DDR pathways, leading to the
co-invention of a CD13-activated drug delivery platform and establishing his
expertise in translational drug design.
Following his PhD, Dr Barnieh
conducted postdoctoral research at the Institute of Cancer Therapeutics, where
he developed advanced analytical and high-throughput screening platforms to
study drug metabolism and glycosylation-related targets. In 2021, he secured a
competitive UKRI-UoB STARTER Fellowship, enabling him to
initiate independent research on tumour-specific glycosylation of CD13. He was
subsequently appointed Research Fellow, where his work with Professor
El-Khamisy on cancer dormancy led to the discovery of a novel therapeutic
target and a first-in-class treatment strategy, now protected by an
international patent.
In
2026, Dr Barnieh was awarded the prestigious Wellcome Accelerator Award and now leads an
independent research programme focused on understanding how cancer cells adapt
to low-oxygen (hypoxic) microenvironments and how these adaptations drive
treatment resistance and disease recurrence. He has shown that hypoxic cancer
cells rely on ATR kinase for survival, providing proof-of-concept that
hypoxia-associated vulnerabilities can be selectively targeted without harming
normal tissue. Building on this, his group is developing targeted strategies to
inhibit ATR activity in hypoxic tumour cells, enabling selective eradication of
resistant tumour populations, alongside the development of hypoxia-activated,
tumour-selective DDR-targeting therapeutics.
In
addition to his research, Dr Barnieh plays an active leadership role within the
cancer research community. He has served as ECR Representative on the Executive
Committee, British Association for Cancer Research, where he led the inaugural
Trailblazers conference and contributed to national initiatives supporting
early-career researchers. He also serves as a mentor to several early-career
researchers of Black ethnicity across the UK, supporting diversity and
inclusion within the scientific community.
Dr Barnieh is committed to
mentorship, teaching, and community engagement. He has supervised numerous MSc
and MPharm students, co-supervises doctoral researchers, and contributes to
teaching in cancer biology and drug discovery. He also serves as a peer reviewer
for leading journals and major funding bodies, reflecting his growing
international recognition.
