The FES locus encodes a unique nonreceptor protein-tyrosine kinase (FES) traditionally viewed as a proto-oncogene but more recently implicated as a tumor suppressor in colorectal cancer (CRC).
Taken together, this study provides the first evidence that Blu9931 functions as a FGFR4-selective inhibitor in colorectal cancer (CRC) cells, and Blu9931 may be a new targeted drug.
A recent study revealed that single nucleotide polymorphism (SNP) at codon 388 (Gly or Arg) of fibroblast growth factor receptor 4 (FGFR4) was associated with prognosis in patients with carcinoma of the breast and colorectal carcinoma.
FGFR4 expression levels are very restricted in adult tissues, except in several solid tumors including colorectal cancer, which showed overexpression of FGFR4.
