Left: sPLS-DA wt variant of the gene hOGG1 (green points and arrows) vs. mut and het variant (red), considering all the 56 differentially expressed microRNAs of Sisto et al. (17). Right: representation of the original variables in the 2d space of the transformed variables. Only the three microRNAs with a correlation higher than 0.75 are shown by the black arrows. The blue arrows represent the direction of maximal discrimination between the two groups.
