EPHA1 expression lower in cancer tissues than normal onesPositive EPHA1 staining linked to aggressive tumor featuresPositive EPHA1 associated with poor OSEPHA1 expression higher in metastatic than primary lesionsPatients with tumors that were:○EPHA1/ EPHA2 (+)○EPHA1/ ephrin-A1 (+)showed shorter OS. This evidence concerns the gene EFNA1 and cancer.
