WNT AND FRIZZLED RECEPTORS AS TARGETS FOR IMMUNOTHERAPY IN HEAD AND NECK SQUAMOUS CELL CARCINOMAS

摘要

The diverse receptor-ligand pairs of the Wnt and frizzled (Fzd) families play important roles during embryonic development, and thus may be overexpressed in cancers that arise from immature cells. The mRNA levels and expression levels of 5 Wnt (Wnt-1, 5a, 7a, 10b, 13) and 2 Fzd (Fzd-2, 5) genes in 10 head and neck squamous carcinoma cell lines (HNSCC) were investigated. In addition, anti-Wnt-1 antibodies were used to study the Wnt/Fzd signalling pathway. These results indicate that HNSCC cell lines overexpress one or more Wnt and Fzd genes, and the growth and survival of a subset of HNSCC may depend on the Wnt/Fzd pathway. Therefore, The Wnt and Fzd receptors may be useful targets for immunotherapy of this common cancer.
