Figure 4: Correlated lncRNA and coding RNA expression in mammary tissues after low-dose radiation exposure. (a) Correlation graphs of the average expression values from each experimental treatment group for each mRNA and lncRNA differentially expressed after LDIR at each of the four timepoints. Positive and negative correlations are indicated in blue and yellow, respectively. (b) Representative examples of networks of lncRNAs (purple) significantly correlated in expression with mRNAs (pink).
