STAT3 and age-related macular degeneration: Integration of cell-type-specific single-cell RNA sequencing data from AMD-RPE clusters identified cluster-specific gene hubs and vertical signaling axes, leading to VEGF blockade failure.<h4>Results</h4>EGFR, HSP90AA1, SIRT1, and STAT3 emerged as central resistance hubs linking angiogenesis and inflammatory processes.
