Effect of chronic Pb exposure on NDR1/2 expression in rat brain was subject to mixed factors of brain regions×age×gender.

<p>Representative Immunoblot and histograms plot showed the protein expression of NDR1/2 in male hippocampus at PND30, PND60, PND90, respectively (A), in male mPFC at PND30, PND60, PND90, respectively (B), in female hippocampus at PND30, PND60, PND90, respectively (C), in female mPFC at PND30, PND60, PND90, respectively (D). Data are expressed as mean ± SEM. *P<0.05, **P<0.01. n = 8 per group.
