Figure 1From: Changes in HSP gene and protein expression in natural scrapie with brain damageGene expression profiles of four chaperone genes ( HSP27 , HSP72 , HSP73 , and HSP90 ) in four CNS areas of control (grey bars) and scrapie (black bars) sheep in the medulla oblongata (a), diencephalon (b), prefrontal cortex (c), and cerebellum (d). Differences between groups were analysed using the Student's t-test (*p < 0.05, **p < 0.01).Back to article page
