Special Issue Information

Dear Colleagues,

This Special Issue of International Journal of Molecular Sciences focuses on the interplay between epigenetics and metabolism in physiological and pathological conditions.

Numerous studies have indicated that cellular metabolism and epigenetics are highly interconnected, contributing not only to physiological changes but also to numerous differnt human disorders and cancers. The epigenetic regulation of genes mediated by DNA- and histone-modifying enzymes (DNMT, HAT, HDAC, KAT, KDM, BET, etc.) is influenced by oncogene-mediated metabolic alterations. Such metabolic changes affect the presence or accesibility of cofactors that are required for the catalytic activity of epigenetic modifying enzymes. In addition, these metabolic alterations may produce oncometabolites that abnormally activate or inhibit such modifying enzymes, altering the epigenome. And, vice versa, epigenetic deregulation impacts metabolic gene expression in cancers, resulting in metabolomic alterations. As a result, the interplay between metabolism and epigenetics is crucial for the development of human diseases and tumorigenesis. Discovering novel molecular mechanisms linking the two pathways and targeting their downstream substrates could provide novel therapeutic targets to treat patients with different diseases.

In this issue, we are particularly interested in the regulation and mechanism of epigenetic enzymes and metabolic enzymes in cancer.

We warmly welcome submissions, including original research manuscripts and comprehensive reviews, on this exciting topic.

The significance of glutamine in cancer metabolism has been extensively studied. Cancer cells consume an excessive amount of glutamine to facilitate rapid proliferation. Thus, glutamine depletion occurs in various cancer types, especially in poorly vascularized cancers. This makes glutamine synthetase (GS), the only enzyme responsible for de novo synthesizing glutamine, essential in cancer metabolism. In cancer, GS exhibits pro-tumoral features by synthesizing glutamine, supporting nucleotide synthesis. Furthermore, GS is highly expressed in the tumor microenvironment (TME) and provides glutamine to cancer cells, allowing cancer cells to maintain sufficient glutamine level for glutamine catabolism. Glutamine catabolism, the opposite reaction of glutamine synthesis by GS, is well known for supporting cancer cell proliferation via contributing biosynthesis of various essential molecules and energy production. Either glutamine anabolism or catabolism has a critical function in cancer metabolism depending on the complex nature and microenvironment of cancers. In this review, we focus on the role of GS in a variety of cancer types and microenvironments and highlight the mechanism of GS at the transcriptional and post-translational levels. Lastly, we discuss the therapeutic implications of targeting GS in cancer. Full article
