The findings that we present here are consistent with those results and actually were obtained before our last works [26,27], but remain unpublished because by the time we finish recollecting the tissue samples we used for the present Affymetrix analysis, we had started outcrossing the AQP4−/−-CD1 mice with WT-C57BL/6 animals to obtain a C57BL/6 genetic background of the AQP4-KO animal, and unfortunately by doing that we lost the sporadic obstructive hydrocephalus phenotype, making impossible to validate our results in this type of hydrocephalus animal. The gene discussed is AQP4; the disease is obstructive hydrocephalus.
