Spearman correlation coefficient p-values: *** < 1e-09, ** < 1e-06, * < 1e-03, NS not significant

Spearman correlation tests performed on D. melanogaster gene expression data from developmental series experiments (see Additional file 4) using R (http://www.r-project.org/ webcite) show that the expression profiles of TipE gene family members are well-correlated, as well as with Para and Slowpoke. However, the expression profiles of these genes exhibit poor correlation with the host gene of TipE gene cluster, CG18675.
