Abstract:
The metabolism of tumors and immune cells in the tumor microenvironment (TME) can affect the fate of cancer and immune responses. Metabolic reprogramming can occur following the activation of metabolic-related signaling pathways, such as phosphoinositide 3-kinases (PI3Ks) and the mammalian target of rapamycin (mTOR). Moreover, various tumor-derived immunosuppressive metabolites following metabolic reprogramming also affect antitumor immune responses. Evidence shows that intervention in the metabolic pathways of tumors or immune cells can be an attractive and novel treatment option for cancer. For instance, administrating inhibitors of various signaling pathways, such as phosphoinositide 3-kinases (PI3Ks), can improve T cell-mediated antitumor immune responses. However, dual pathway inhibitors can significantly suppress tumor growth more than they inhibit each pathway separately. This review discusses the latest metabolic interventions by dual pathway inhibitors as well as the advantages and disadvantages of this therapeutic approach.
Insights

Area of Science:
- Oncology
- Immunology
- Metabolic pathways
Background:
- Tumor and immune cell metabolism within the tumor microenvironment (TME) critically influences cancer progression and immune responses.
- Metabolic reprogramming, often driven by signaling pathways like phosphoinositide 3-kinases (PI3Ks) and mammalian target of rapamycin (mTOR), alters the TME.
- Tumor-derived metabolites can suppress crucial antitumor immune responses.
Purpose of the Study:
- To review the latest advancements in metabolic interventions for cancer treatment.
- To focus on the efficacy and implications of dual pathway inhibitors targeting metabolic pathways.
- To discuss the advantages and disadvantages of this novel therapeutic strategy.
Main Methods:
- Review of current literature on metabolic reprogramming in cancer and immunology.
- Analysis of signaling pathways such as PI3K/mTOR in cancer metabolism.
- Examination of dual pathway inhibitors and their impact on tumor growth and immune responses.
Main Results:
- Intervention in tumor or immune cell metabolic pathways presents a novel cancer treatment option.
- Inhibitors of pathways like PI3K can enhance T cell-mediated antitumor immunity.
- Dual pathway inhibitors demonstrate superior tumor growth suppression compared to single pathway inhibitors.
Conclusions:
- Metabolic interventions, particularly dual pathway inhibitors, offer a promising therapeutic avenue for cancer.
- Understanding the interplay between cancer metabolism and the immune system is key to developing effective treatments.
- Further research into the advantages and disadvantages of dual pathway inhibitors is warranted for clinical application.
