Affymetrix Zebrafish Genome Array (zebrafish)
Description
An experiment was performed to analyze the effect of knockdown of dpf3 during zebrafish embryogenesis.Morpholino against dpf3 and control morpholino were injected into eggs and eggs were kept under standard conditions for 72 hours. Embroys were harvested, total RNA was extracted and used for microarray analysis.

- Affymetrix Mouse Expression 430A Array (moe430a)
Description
Deprivation of peripheral nerve input by cochlear removal in young mice results in dramatic neuron death in the cochlear nucleus (CN). The same manipulation in older mice does not result in significant loss. The molecular basis of this critical period of vulnerability remains largely unknown. Here we identified genes regulated at early time points after cochlear removal at ages when neurons are vulnerable (postnatal day (P)7) or invulnerable (P21) to this challenge. Afferent deprivation regulated very different sets of genes at P7 and P21. These genes showed a variety of functions at both ages, but surprisingly there was no net increase in pro-apoptotic genes at P7. A large set of upregulated immune-related genes was identified at P21.

- Affymetrix Mouse Genome 430A 2.0 Array (mouse430a2)
Description
We analyzed whether cochlear removal-induced transcriptional changes in the cochlear nucleus (CN) were due to loss of electrical activity in the 8th nerve. Pharmacological activity blockade of the auditory nerve for 24 h resulted in similar expression changes for only a subset of genes. Thus, an additional factor not dependent on action potential-mediated signaling must also regulate transcriptional responses to deafferentation in the CN.
