Answer: chemicals in the body.

Explanation: gene expression is regulated by chemical signals (hormones, growth factors, transcription factors, metabolites, epigenetic modifiers). Protein synthesis is the outcome of gene expression, senescence/aging can alter expression but is not a primary regulatory factor in general, and "the brain" is just one organ that can send signals (hormones/neuronal signals) rather than a direct determinant.
