Abstract Glutamine metabolism in tumor microenvironments critically regulates antitumor immunity. Using the glutamine-antagonist prodrug JHU083, we report potent growth inhibition urologic tumors by JHU083-reprogrammed tumor-associated macrophages (TAMs) and tumor-infiltrating monocytes. We show JHU083-mediated glutamine antagonism induced TNF, proinflammatory, mTORC1 signaling intratumoral TAM clusters. TAMs also exhibited increased cell phagocytosis diminished proangiogenic capacities. In vivo of consumption resulted glycolysis, a broken tricarboxylic acid (TCA) cycle, purine disruption. Although effect on T cells was moderate, JHU083 promoted stem cell–like phenotype CD8+ decreased abundance regulatory cells. Finally, caused global shutdown glutamine-utilizing metabolic pathways cells, leading to reduced HIF-1α, c-MYC phosphorylation, induction apoptosis, all key features. Altogether, our findings demonstrate that targeting with led suppressed as well reprogramming immunosuppressive within prostate bladder immune responses. can offer an effective therapeutic benefit for types are enriched TAMs.

Tumor-associated macrophages microglia (TAMs) are dominant population of immune cells GBM TME that contribute to hallmarks, including immunosuppression. The understanding TAMs has been limited by lack powerful tools characterize them. However, recent progress on single-cell technologies offers an opportunity precisely at level identify new TAM subpopulations with specific tumor-modulatory functions GBM.

Abstract Given that hypoxia is a persistent physiological feature of many different solid tumors and key driver for cancer malignancy, it thought to be major target in treatment recently. Tumor-associated macrophages (TAMs) are the most abundant immune cells tumor microenvironment (TME), which have large impact on development immunotherapy. TAMs massively accumulate within hypoxic regions. represent deadly combination because has been suggested induce pro-tumorigenic macrophage phenotype. Hypoxia not only directly affects polarization, but also an indirect effect by altering communication between macrophages. For example, can influence expression chemokines exosomes, both profound impacts recipient cells. Recently, demonstrated intricate interaction TME relevant poor prognosis increased malignancy. However, there no comprehensive literature reviews molecular mechanisms underlying hypoxia-mediated TAMs. Therefore, this review aim collect all recently available data topic provide insights developing novel therapeutic strategies reducing effects hypoxia.

Few metabolites can claim a more central and versatile role in cell metabolism than acetyl coenzyme A (acetyl-CoA). Acetyl-CoA is produced during nutrient catabolism to fuel the tricarboxylic acid cycle essential building block for fatty isoprenoid biosynthesis. It also functions as signalling metabolite substrate lysine acetylation reactions, enabling modulation of protein response acetyl-CoA availability. Recent years have seen exciting advances our understanding normal physiology cancer, buoyed by new mouse models, vivo stable-isotope tracing approaches improved methods measuring acetyl-CoA, including specific subcellular compartments.
