High-throughput acoustic FFPE proteomics reveals ATP5IF1-associated mitochondrial alterations in acral melanoma.
A new lab technique analyzes archived tumor samples to reveal hidden molecular features in rare melanoma subtypes, enabling discovery of treatment vulnerabilities.
This study establishes a scalable acoustic FFPE proteomics workflow and applies it to acral melanoma—a melanoma subtype with distinct biology, occurring predominantly on palmar/plantar sites and more common in Asian populations—identifying mitochondrial protein alterations including ATP5IF1 as novel molecular features. The FFPE-compatible high-throughput platform overcomes a longstanding barrier to proteomic analysis of large archival clinical cohorts, enabling discovery of subtype-specific vulnerabilities in rare cancers.
