to evaluate the potential of growth, invasion and metastasis of endometrial cancer cells associated with neovascularization, the expression of basic fibroblast growth factor (FGF) and its mRNA in endometrial cancers and normal endometria as controls was determined by enzyme-linked immunosorbent assay, reverse transcription-polymerase chain reaction and Southern blot. the relationship between FGF expression and histological grades, and the degree of myometrial invasion or clinical stages of endometrial cancers were analyzed. The level of basic FGF was found significantly higher in endometrial cancers of G3 and stage III-IV compared to normal endometria. Likewise, the level of basic FGF mRNA was significantly higher in endometrial cancers of G3, level C and stage IV-IV compared to normal endometria. In cancers of other categories, G1 and G2, levels of A and B, and stage I evaluation in the levels of basic FGF and its mRNA did not differ significantly from those in normal endometria. Since lethal lesions are mostly confined to endometrial cancers of G3, level C, and stages III-IV, the increase of basic FGF, which leads to neovascularization, could be one of the characteristics of highly malignant and /or advanced endometrial cancers, and may contribute to the acceleration of growth, invasion, and metastasis.

The aim of this study was to identify amplified oncogenes in endometrial cancer using array-based comparative genomic hybridization (array CGH). Despite its prevalence, the molecular mechanisms of endometrial carcinogenesis are still poorly understood. The selected array CGH allows the simultaneous examination of 58 oncogenes commonly amplified in human cancers and is capable of achieving increased mapping resolution compared with conventional CGH. A subset of 8 specimens from a bank of 60 malignant and normal specimens was selected for array analysis to identify potential genes of interest. TaqMan polymerase chain reaction was carried out on the 60 specimens to examine if aberrations at the genomic level correlated with gene expression and to compare expression in normal and malignant samples. Oncogenes amplified in the endometrial cancers included AR, PIK3CA, MET, HRAS, NRAS, D17S1670, FGFR1, CTSB, RPS6KB1, LAMC2, MYC, PDGFRA, FGF4/FGF3, PAKI, and FGR. Three genes were examined at the messenger RNA level. AR and PIK3CA were higher in normal specimens, and MET was higher in malignant samples, suggesting a role for MET in endometrial cancer. Newer arrays examining more genes and larger sample numbers are necessary to elucidate the carcinogenic pathway in endometrial cancer.

Angiopoietin-1 (ANGPT1), Angiopoietin-4 (ANGPT4), VEGF, FGF2, FGF4, HGF, Ephrin, IL8 and CXCL12 (SFD1) are pro-angiogenic factors (angiogenic activators), while Angiopoietin-2 (ANGPT2), Angiostatin, Endostatin, Tumstatin, Canstatin, THBS1, THBS2, TNFSF15 (VEGI) and Vasohibin (VASH1) are anti-angiogenic factors (angiogenic inhibitors). ANGPT1 and ANGPT2 are ligands for TIE family receptor tyrosine kinases, TIE1 and TIE2 (TEK). Angiopoietin family consists of ANGPT1, ANGPT2, ANGPT4, ANGPTL1 (ANGPT3), ANGPTL2, ANGPTL3 (ANGPT5), ANGPTL4, ANGPTL5, ANGPTL6 and ANGPTL7. TCF/LEF binding sites within the promoter region of human Angiopoietin family members were searched for by using bioinformatics and human intelligence (Humint). Because four TCF/LEF-binding sites were identified within the human ANGPTL7 promoter, comparative genomics analyses on ANGPTL7 orthologs were further performed. ANGPTL7 gene at human chromosome 1p36.22 was located within intron 28 of FRAP1 gene encoding mTOR protein. Chimpanzee ANGPTL7 gene, consisting of five exons, was located within NW_101546.1 genome sequence. Chimpanzee ANGPTL7 showed 99.4% and 86.1% total-amino-acid identity with human ANGPTL7 and mouse Angptl7, respectively. Human ANGPTL7 mRNA was expressed in neural tissues, keratoconus cornea, trabecular meshwork, melanotic melanoma and uterus endometrial cancer, while mouse Angptl7 mRNA was expressed in four-cell embryo, synovial fibroblasts, thymus, uterus and testis. Four TCF/LEF-binding sites within human ANGPTL7 promoter were conserved in chimpanzee ANGPTL7 promoter; however, only an unrelated TCF/LEF-binding site occurred in mouse and rat Angptl7 promoters. Human ANGPTL7, characterized as potent target gene of WNT/ beta-catenin signaling pathway, is a pharmacogenomics target in the fields of oncology and regenerative medicine.

FGFR2 gene encodes FGFR2b in epithelial cells, and FGFR2c in mesenchymal cells. FGFR2b is a high affinity receptor for FGF1, FGF3, FGF7, FGF10 and FGF22, while FGFR2c for FGF1, FGF2, FGF4, FGF6, FGF9, FGF16 and FGF20. Here genomics and genetics of FGFR2, and therapeutics targeted to FGFR2 will be reviewed. Single nucleotide polymorphisms (SNPs) of FGFR2 are associated with increased risk of breast cancer. Gene amplification or missense mutation of FGFR2 occurs in gastric cancer, lung cancer, breast cancer, ovarian cancer, and endometrial cancer. Genetic alterations of FGFR2 induce aberrant FGFR2 signaling activation due to release of FGFR2 from autoinhibition, or creation of FGF signaling autocrine loop. Class switch of FGFR2b to FGFR2c is associated with more malignant phenotype. FGF and canonical WNT signals synergize during mammary carcinogenesis, but counteract during osteogenesis and adipogenesis. Among PD173074, SU5402, and AZD2171 functioning as FGFR inhibitors, AZD2171 is the most promising anti-cancer drug. Cancer genomics and genetics are utilized to predict cancer-driving pathway for therapeutic optimization. FGFR2ome is defined as a complete data set of SNP, copy number variation (CNV), missense mutation, gene amplification, and predominant isoform of FGFR2. FGFR2ome analyses in patients with several tumor types among various populations should be carried out to establish integrative database of FGFR2 for the rational clinical application of FGFR2-targeted cancer therapy.
