Effect of over-expressing NRF-2α and β on the transcript
and protein levels of COX7c and AMPA receptor subunit genes.
(A) NRF-2α/β over-expression increased protein levels of
NRF-2α and NRF-2β, as well as GluA2 (lane 2) as compared to
controls (lane 1). Protein levels of GluA1 did not increase significantly with
NRF-2α/β over-expression. β-actin served as a loading
control. N = 3 for each data point; ***= P < 0.001 when
compared to pcDNA3.1 empty vector controls. (B) Real-time PCR revealed an
up-regulation of NRF-2α and β
mRNA with NRF-2α/β over-expression as compared to pcDNA3.1 empty
vector controls. (C) In N2a cells, mRNA levels of Gria2, but
not those of Gria1, Gria3, and
Gria4, were increased with NRF-2α/β
over-expression. mRNA levels of the positive control, COX7c,
were also increased with NRF-2α/β over-expression. N = 6 for
each data point. **= P < 0.01 and ***=
P < 0.001 when compared to pcDNA3.1 empty vector
controls.
