    1. our study demonstrated that FGFR4 rs2011077 and rs1966265 are associated with the progression of cervical normal tissues to precancerous lesions in Taiwanese women. Moreover, rs351855 (Gly388Arg) is the only FGFR4 genetic polymorphism that is associated with patient survival. PMID: 28378614
    2. Thus, we conclude that the oncoprotein HBXIP up-regulates FGF4 through activating transcriptional factor Sp1 to promote the migration of breast cancer cells. Therapeutically, HBXIP may serve as a novel target in breast cancer. PMID: 26828265
    3. Fibroblasts induce expression of FGF4 in ovarian cancer stem-like cells/cancer-initiating cells and upregulate their tumor initiation capacity. PMID: 25329002
    4. Data show that the interaction between Artd1 and Sox2 is crucial for the first steps of the reprogramming process and that early expression of Fgf4 is an essential component for the successful generation of iPSCs. PMID: 23939864
    5. Myoblasts which overexpress FGF-4 exhibit significant changes in cell cycle and pro-angiogenic potential with only slight differences in the expression of the myogenic genes. PMID: 21673370
    6. In vivo stimulation of BT-474 cell growth by progesterone is associated with up-regulation of FGF4 which may promote tumor growth and maintenance. PMID: 22237711
    7. knockdown of FGFR4 expression led to decreased proliferation and an increased rate of apoptosis in the MKN45 and SGC7901 GC cell lines PMID: 21567388
    8. activation of human HST-1 gene in transgenic mice induces spermatogenesis and prevents adriamycin-induced testicular toxicity PMID: 11840335

    12. Both myeov and hst (fgf4) are normally situated approximately 475-kb apart at band 11q13, a region that is frequently amplified and overexpressed in various tumours. PMID: 17390055
    13. FGF-4 increases the rate at which MSC proliferate and has no significant effect on MSC pluripotency PMID: 17852409
    14. These results suggest a growth-promoting role for FGF4 in human embryonic stem cells and a putative feedback inhibition mechanism by a novel FGF4 splice isoform that may serve to promote differentiation at later stages of development. PMID: 18192227
    15. Implantation of human FGF4-soaked beads is sufficient to restore expression of G1- and S-phase cell-cycle genes and S-phase progression in zebrafish sonic hedgehog (Shh) mutant fin buds. PMID: 18811955
