Scatterplot depicting the positive correlation between HSF1 mRNA expression values and Alu RNA processing ratio in MAP AD patients (r=0.72, p<0.001). Statistical test is based on Pearson's product moment correlation coefficient and follows a t distribution using the cor.test function in R package stats. Scatterplot depicting lack of correlation between HSF1 mRNA expression values and full length Alu RNA levels in MAP AD patients (ns=non-significant, with p value 0.05 as the significance threshold). Statistical test as in subfigure 8E.
