Ageing Hallmarks Exhibit Organ-Specific Temporal Signatures

Ageing Hallmarks Exhibit Organ-Specific Temporal Signatures

"Revealed (in this research) are linear and nonlinear shifts in gene expression during ageing, with the associated genes clustered in consistent trajectory groups with coherent biological functions—including extracellular matrix regulation, unfolded protein binding, mitochondrial function, and inflammatory and immune response. Notably, these gene sets show similar expression across tissues, differing only in the amplitude and the age of onset of expression. Widespread activation of immune cells is especially pronounced, and is first detectable in white adipose depots during middle age."
