Gene expression is primarily determined by **protein synthesis** and the regulatory mechanisms that influence it, including transcription factors, epigenetic modifications, and various signaling pathways. Other factors such as environmental conditions and chemicals in the body can also play a role in regulating gene expression. However, **senescence** and **the brain** are not direct factors influencing gene expression in the general sense.

Therefore, the most relevant response from your options is **protein synthesis**.
