Overview of significant probes in microarray analysis. An overview is shown of the probes presenting significant sex-biased signals in five tissues. A: Tissues analysed using Illumina 6v1.1 platform (striatum and neocortex). B: Tissues analysed using Affymetrix M430v2.0 platform (hippocampus, eye and lung). Columns designate samples (F: females, M: males) and rows designate probes. Yellow colour denotes up-regulation and blue colour denotes down-regulation of a gene in a sample, as compared to the overall mean expression of the particular gene within a tissue in the sex-balanced data sets.
