Altered light induced EGR1 expression in the SCN of PACAP deficient mice
Fig 4
Immunohistochemistry of coronal sections of the mid SCN stained for EGR1 protein at early night (ZT 17).
The core and ventral shell (retinorecipient) and shell portion of the mid SCN [41] is indicated in panel C. Animals were fixed 60 min after a 30 min light stimulation at 300 lux (A and B) or 10 lux (C and D). OC, optic chiasm, Scale bars = 50 μm.
