Figure 4From: Gene expression changes in aging Zebrafish (Danio rerio) brains are sexually dimorphicRelative expression values from the microarray and real-time PCR experiments for A) pvalb8 and B) smurf2. Values on the x-axis are the relative expressions in each group. In each graph the value for females are set to 1 as the reference for each group. F; female, M; male, Y; young, O; old. Error bars indicate the standard error, n =?6. *: p < 0.05.Back to article page
