Western blot analysis was performed as previously described [1 (link)] using BDNF (1:2,000; GeneTex, Irvine, CA, USA) and GAPDH (1:5000; Cell Signaling, Danvers, MA, USA) antibodies. Signal detection was performed using the LAS-2000 system (LAS-2000; Fuji, Tokyo, Japan) with enhanced chemiluminescence (Western-CDP star; PerkinElmer Life Sciences, Norwalk, CT, USA). Densitometric analysis of immunoreactivity for each protein was conducted using NIH ImageJ software.
