Correlation of Mena isoform expression to TMEM score.

Jeanine Pignatelli et al., Sci. Signal. 2014;7:ra112


Correlation of MenaINV-TMEM scores in different grades of human IDCs.(A) Scatter plots of relative MenaINV transcript expression against TMEM score in IDCs of different grades.



Correlation of E-cadherin and TMEM and MenaINV scores.



iTEM assays using human patient IDC cells obtained from FNA biopsies.



MenaINV is required for macrophage-induced iTEM in MDA-MB-231 TN breast cancer cells.



CSF1R expression in iTEM-competent cells differs among breast cancer subtypes.



Primary human macrophages increase iTEM of primary human breast cancer cells.



Model of MenaINV- and macrophage-mediated tumor cell invasion and TEM.ITEM-competent human breast cancer cells from all clinically relevant subtypes display MenaINV high/Mena11a low

isoform expression and perivascular macrophages promote endothelia
