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we present here are consistent with those results and actually were obtained before our last works [26,27], but remain unpublished because by the time we finish recollecting the tissue samples we used for the present Affymetrix analysis, we had started outcrossing the AQP4−/−-CD1 mice with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. This evidence concerns the gene AQP4 and Hydrocephalus.
