Abstract

PURPOSE: The molecular landscape of breast cancer (BC), especially of the Luminal A subtype, remains to be fully delineated. Transcriptomic data show that Luminal A tumours are enriched for aberrant expression of genes in the cell division control 42 homolog (CDC42) pathway. This study aims to investigate the protein expression of CDC42 in BC and assess its clinicopathological significance. METHODS: Expression of CDC42 protein was examined by immunohistochemistry on tissue microarrays in a well-characterised cohort of 895 early-stage (I-IIIa) primary invasive BCs. RESULTS: CDC42 expression was observed in both the cytoplasm and the nucleus of BC cells. High nuclear CDC42 expression demonstra..
