The table reveals details of each individual Src kinase family member and the housekeeping gene HPRT. Expression levels of Src kinase family members in different breast tissue types are stated as medians. P-values express alterations of expression in the different breast tissue types (Kruskal–Wallis test). Bold typeface is used to highlight significant P-values.
