Anti‐Tumor Strategies Targeting Nutritional Deprivation: Challenges and Opportunities

Abstract

AbstractHigher and richer nutrient requirements are typical features that distinguish tumor cells from AU: cells, ensuring adequate substrates and energy sources for tumor cell proliferation and migration. Therefore, nutrient deprivation strategies based on targeted technologies can induce impaired cell viability in tumor cells, which are more sensitive than normal cells. In this review, nutrients that are required by tumor cells and related metabolic pathways are introduced, and anti‐tumor strategies developed to target nutrient deprivation are described. In addition to tumor cells, the nutritional and metabolic characteristics of other cells in the tumor microenvironment (including macrophages, neutrophils, natural killer cells, T cells, and cancer‐associated fibroblasts) and related new anti‐tumor strategies are also summarized. In conclusion, recent advances in anti‐tumor strategies targeting nutrient blockade are reviewed, and the challenges and prospects of these anti‐tumor strategies are discussed, which are of theoretical significance for optimizing the clinical application of tumor nutrition deprivation strategies.
