Gene expression becomes heterogeneous with age
... among somatic cells increases with age [1–5]. However, no evidence for an age-dependent increase in variation in gene expression has yet been found [6–9]. Using eight microarray data sets from different studies in humans and rats, we find that gene expression becomes more variable with advancing age ...
