To study the prevalence of ERMP1 and its potential clinical significance IHC analysis with ERMP1 mAb was performed on TMAs carrying different sets of well-characterized FFPE samples from breast (136 cases, in duplicate), colon (CRC) (667 cases), lung (368 cases of Non-Small-Cell Lung Carcinoma (NSCLC) and ovary (150 cases) cancers, selected on the basis of the availability of relevant clinical and molecular data (Supplementary Table S1). Here, ERMP1 is linked to non-small cell lung carcinoma.
