As modern society is graying, aging research and biogerontology models, in which the aging process can be studied, are becoming increasingly important. A proper aging model can be defined as one that displays many of the aging hallmarks. Here, we provide two different practical approaches-namely, real-time quantitative polymerase chain reaction (RT-qPCR) and western blotting-that can be used to investigate cellular senescence (RT-qPCR for p21 and p27), altered intercellular communication/inflammaging (RT-qPCR for il-10, sirt-1, il-6, il-1b, il-8, and tnf), and oxidative stress (western blotting for 4-HNE) in the killifish central nervous system, and, more specifically, in the retina, optic tectum, and telencephalon. These molecular and biochemical analyses are a first step in confirming the aging characteristics but should preferably be combined with morphological analyses.
