Membranous CD44v6 is upregulated as an early event in colorectal cancer: Downregulation is associated with circulating tumor cells and poor prognosis.

ABSTRACT: Previous studies have reported that CD44 variant 6 (CD44v6) and metastasis-associated protein 1 (MTA1) are contributing factors to cancer progression. The present study aimed to evaluate the expression profiles for associations with patients' demographic data, clinicopathological characteristics, the presence of partial epithelial-to-mesenchymal transition (pEMT), metastatic potential based on the presence of CK20⁺ CEA⁺ CXCR4⁺ circulating tumor cells (CTCs) and prognosis (median follow-up, 45 months). Thus, frozen tissue samples from 31 patients with stage I-III colorectal cancer (CRC), 15 benign colorectal polyps and seven normal colorectal tissues were analyzed to detect membranous (m)CD44v6 and MTA1 expression via flow cytometry. The results demonstrated
