Postnatal Development of Mouse Cochlear Nucleus

Developmental differences in gene expression in the postnatal mouse cochlear nucleus was analyzed at two or three ages using two different array platforms, the Affymetrix Mouse 430A GeneChip or the NIA 15K mouse cDNA microarray. These ages, P7, P14, and P21 parallel a critical period of neuron survival dependent on input from the auditory nerve. Keywords: parallel sample Comparison of baseline gene expression in the CN at P7, P14, and P21 using Affymetrix 430A chips or NIA 15K cDNA mouse array. For Affy chips, 3 replicates were done at P7 and P21, 2 replicates at P14. For NIA arrays, 5 replicates were done comparing P7 and P21. There was one dye flip included.
