Hidden metabolism found operating inside the cell nucleus
General • March 9, 2026
Researchers have found
hundreds of
metabolic enzymes
attached to human DNA
inside the cell nucleus. Different tissues and cancers show unique patterns of these enzymes, forming a “nuclear metabolic fingerprint.” Some of the enzymes gather around damaged DNA to assist with repair. The discovery reveals an unexpected link between metabolism and gene regulation that could influence how cancers grow and respond to treatment.
