WDR26 and ductal breast carcinoma in situ: Given the correlation between high expression of TROLL-2 and TROLL-3, WDR26 localization, and AKT phosphorylation in DCIS derived tumours, we tested whether such correlation was also present in the breast cancer TMAs that we assessed for the ISH of TROLL-2 and TROLL-3 and the IHC of WDR26.
