Tumor heterogeneity: development, mechanisms, and therapeutic implications.
Real-time monitoring of how tumors evolve genetically and within their microenvironment reveals therapeutic targets in cancer's dynamic ecosystem, not just its static snapshot.
This Signal Transduction and Targeted Therapy review synthesizes advances in understanding tumor heterogeneity from its origins in genomic instability and clonal evolution through its multidimensional manifestation in the tumor microenvironment, covering both intra-tumor and inter-tumor heterogeneity. The review critically examines how single-cell RNA-seq, spatial transcriptomics, and liquid biopsy are enabling real-time monitoring of tumor evolution, while outlining emerging therapeutic paradigms — including targeting clonal cooperative networks, epigenetic reprogramming, and metabolic adaptation — toward reconceptualizing cancer as a dynamically evolving ecosystem.
