From the (Epi)Genome to Metabolism and Vice Versa; Examples from Hematologic Malignancy

Area of Science:

• Hematology
• Cancer Biology
• Metabolic Regulation

Background:

• Hematologic malignancies (leukemias, lymphomas, myelomas) arise from hematopoietic cells.
• Genetic mutations are key drivers, conferring growth advantages to cancer cells.
• These mutations affect transcription factors, epigenetic regulators, and metabolic enzymes.

Purpose of the Study:

• To overview metabolic changes and genetic alterations in malignant hematopoiesis.
• To discuss how metabolites regulate epigenetic events in these cancers.
• To illustrate the genome-epigenome-metabolism interplay in hematologic malignancy.

Main Methods:

• Review of genetic analyses in hematologic malignancies.
• Analysis of metabolic reprogramming in cancer cells.
• Exploration of the bidirectional signaling between metabolites and the nucleus.

Main Results:

• Mutations in key genes lead to metabolic reprogramming.
• Transformed cells exhibit altered biosynthetic needs and stress tolerance.
• Metabolites modulate epigenetic modifications and chromatin landscape.

Conclusions:

• A bidirectional relationship exists between metabolism and epigenetics in hematologic malignancies.
• Metabolic alterations are crucial for cancer cell survival and proliferation.
• Understanding this interplay is vital for targeting hematologic cancers.
