New Zealand faces a unique and pressing challenge with melanoma, the deadliest form of skin cancer, boasting the world's highest incidence and mortality rates. Each year, over 7,000 cases are diagnosed, resulting in around 300 deaths, a statistic driven by the country's high ultraviolet radiation exposure combined with a predominantly fair-skinned population. At the forefront of combating this epidemic are scientists from the University of Auckland, whose innovative research into hard-to-treat subtypes is paving the way for transformative treatments.
Leading this charge are Associate Professor Stephen Jamieson and Dr. Dean Singleton from the Auckland Cancer Society Research Centre and the Centre for Cancer Research. Their work, bolstered by a landmark $1 million grant from the Winn Trust, targets NRAS-mutant melanoma—a subtype affecting 15-20% of cases that currently lacks effective targeted therapies. This research not only promises new hope for patients but also underscores the vital role of New Zealand's higher education institutions in global health advancements.
Melanoma in New Zealand: A National Health Crisis
Melanoma originates from melanocytes, the skin cells responsible for producing melanin, the pigment that gives skin its color. When exposed to excessive ultraviolet (UV) radiation from the sun or tanning beds, these cells can mutate, leading to uncontrolled growth. In New Zealand, factors like proximity to the ozone hole, outdoor lifestyles, and demographics amplify the risk. Pākehā (people of European descent) experience the highest rates, but Māori and Pacific peoples face disproportionately higher mortality despite lower incidence, often due to later diagnoses.
Prevention campaigns such as 'Slip, Slop, Slap, Seek, Slide' have raised awareness, yet diagnosis numbers continue to climb. Early detection via regular skin checks remains crucial, as stage I melanomas have over 99% five-year survival rates, plummeting to under 30% for stage IV. University researchers are bridging the gap between prevention and advanced treatment, leveraging genetic insights to address late-stage challenges.
- High UV index: New Zealand's latitude results in intense summer sun.
- Fair skin prevalence: Low melanin levels increase susceptibility.
- Late presentation: Rural access and awareness gaps contribute to advanced cases.
The University of Auckland's Research Powerhouse
The University of Auckland, New Zealand's leading research institution, hosts world-class facilities like the Auckland Cancer Society Research Centre. Here, multidisciplinary teams integrate pharmacology, molecular biology, and immunology to tackle cancer. Assoc. Prof. Jamieson's expertise in cancer pharmacology and Dr. Singleton's focus on molecular medicine exemplify how higher education drives translational research—from lab bench to bedside.
Their labs utilize the New Zealand Melanoma living biobank, a collection of over 100 patient-derived cell lines representing local melanoma diversity. This resource, unique to the region, enables precise testing of therapies tailored to Kiwi patients. For aspiring researchers, opportunities abound in such environments; explore research jobs in higher education to join similar impactful teams.
Targeting NRAS-Mutant Melanoma: Jamieson's Breakthrough Approach
Neuroblastoma RAS (NRAS) viral oncogene homolog mutations drive about 15-20% of melanomas, activating the mitogen-activated protein kinase (MAPK) pathway for relentless cell proliferation. Unlike BRAF-mutant cases treatable with targeted inhibitors like vemurafenib, NRAS variants resist such drugs, posing significant therapeutic hurdles. Immunotherapies, such as checkpoint inhibitors (e.g., pembrolizumab), succeed in only a subset, leaving poor prognoses.
Assoc. Prof. Stephen Jamieson's team employs CRISPR-Cas9 gene-editing to identify synthetic lethal vulnerabilities. A pivotal discovery by his former PhD student, Andrea Gu, revealed the SHOC2 gene as indispensable for NRAS-mutant cell survival. Disrupting SHOC2 halts growth selectively in these cells, sparing healthy ones. This work, published in *Cancer Communications* in 2025, marks a milestone in precision oncology.
With $200,000 from Cancer Society New Zealand, the team now screens billions of compounds to find SHOC2 inhibitors. The process involves high-throughput assays: cells are exposed to libraries, viable mutants sequenced, and hits validated in animal models. Success could yield a new drug or combo therapy for clinical trials within five years.Read the SHOC2 study
Overcoming Immunotherapy Resistance: Singleton's Innovations
Immunotherapy harnesses the immune system via programmed death-1 (PD-1) blockers, achieving durable responses in 40% of metastatic melanomas. Yet, 60% fail as tumor cells adapt, shifting differentiation states to evade detection—like hiding in plain sight.
Dr. Dean Singleton's lab dissects these mechanisms, focusing on hypoxia-inducible factor (HIF) pathways regulated by prolyl hydroxylase domain 2 (PHD2). Under low oxygen, melanoma cells alter gene expression via PHD2 inhibition, promoting resistance. PhD student Claire Palma's project tests PHD2 activators to resensitize cells.
Step-by-step: 1) Profile resistant cells from biobank; 2) CRISPR knockout PHD2; 3) Assay immune killing; 4) Optimize combos with existing therapies. Early data suggest enhanced T-cell infiltration, a game-changer for non-responders. For career advice on immunology research, visit higher ed career advice.

Real-World Impacts and Patient Stories
For patients like those in Auckland City Hospital trials, these advances mean hope. One anonymous donor shared: "NRAS diagnosis was devastating; new options change everything." Early SHOC2 blockers could extend survival from months to years.
Stakeholders—from Melanoma NZ to oncologists—praise the work's urgency. Challenges persist: trial recruitment, regulatory hurdles, but biobank speeds progress.
Future Outlook: Towards Clinical Trials and Beyond
Timeline: Compound hits 2026-27, preclinical 2028, trials 2030+. Global collaboration, e.g., with Sanger, amplifies reach. Long-term, personalized medicine via genomics could stratify treatments.
