barely significantp = 0.002
By independently comparing the number of lengthening and shortening genes with differential expression changes to those genes without associated expression changes, we observed a higher than expected overlap between genes with both 3′ UTR lengthening and increased expression, and a barely significant overlap between 3′ UTR shortening and decreased expression ( p = 0.002 and p = 0.02, two-sided Fisher’s exact test, Bonferroni correction).
