The authors indicated that Prostaglandin F receptor (PTGFR), Neuronal regeneration related protein (NREP), Small Cajal body-specific RNA 22 (SCARNA22), Dedicator of cytokinesis 9 (DOCK9), Feline leukemia virus subgroup C cellular receptor family, member 2 (FLVCR2), IKAROS family zinc finger 3 (Aiolos) (IKZF3), Ubiquitin-specific peptidase 13 (USP13) and Cytoplasmic linker associated protein 1 (CLASP1) were found to be potential biomarkers, which may support the diagnosis of cancer. This evidence concerns the gene DOCK9 and cancer.
