Figure 2. Protease activity and cleavage products in the entorhinal cortex.

Figure 2

(A) Quantified calpain activity, (B) quantified caspase-3 activity, (C) expression of calpain cleaved spectrin, and (D) expression of caspase-3 cleaved spectrin in the ETC. Calpain and caspase-3 activity represent % of protease cleaved spectrin to uncleaved spectrin (250 kD). Calpain cleaved spectrin (150 kD) and caspase-3 cleaved spectrin (120 kD) expression normalized to β-actin. Raw values are shown and error bars denote mean ± S.E.M. Analyzed by 2-way ANOVA with Fisher’s LSD multiple comparisons tests. Post-hoc significance indicated by: * = p≤0.05. Significant effects observed: (A): CIH X Sex (F1,18=7.565; p=0.013; η2=0.286); (C): CIH X Sex (F1, 20=7.891; p=0.010; η2=0.274); (D): CIH X Sex (F1, 19=4.635; p=0.044; η2=0.190). CIH: Chronic intermittent hypoxia; ETC: Entorhinal cortex.
