Decoding Early-Life UVA and Skincare Additive Interactions Driving Melanoma Risk and Progression in Young Adults

Ziel

Malignant melanoma is a leading cause of cancer mortality among young Europeans, despite decades of prevention campaigns. This persistence indicates that factors beyond UVB-induced DNA damage contribute to risk. PhotoMel will reveal how early-life UVA exposure and skincare additives remodel the skin microenvironment to drive melanoma initiation and early spread.

Our overarching objectives are to i) prevent melanoma onset by decoding how chemical exposures modulate UVA-induced skin damage; ii) map multimodal patient biopsy data to resolve spatial tumour-microenvironment interactions; iii) transform mechanistic insights into predictive 3D computational models; iv) predict patient-specific metastatic risk through biomarker discovery; and v) engage citizens and patients to restore trust, guide regulation and strengthen prevention strategies.

We will integrate ex vivo skin models, mutational characterisation, extracellular matrix (ECM) biomechanics, spatial multiomics, advanced microscopy, CROP-seq functional genomics and multiscale computational modelling. Specifically, we will quantify UVA-chemical effects on skin cells and the ECM, define how altered microenvironments shape melanoma subpopulations, and integrate ECM, immune and tumour features into predictive models, delivering biomarker panels for exposure-driven metastatic risk stratification in young people. Patient cohorts and retrospective datasets will validate predictions and connect molecular and mechanical changes to outcomes.

By addressing how childhood and adolescent exposures shape cancer risk in young adults, PhotoMel directly advances the Mission Cancer goal of uncovering environmental determinants of cancer. Outcomes will deliver actionable biomarkers, interoperable datasets and predictive tools for clinicians and policy makers, informing prevention, supporting UNCAN.eu and PARC, and ultimately improving personalised prevention, prediction, quality of life and long-term outcomes for Europe’s youth.

This action is part of the Cancer Mission cluster of projects on “Understanding – environmental exposure in CAYA.
