Database References	HGNC: 3687 OMIM: 600921 KEGG: hsa:2254 STRING: 9606.ENSP00000371790 UniGene: PMID: 30227870 We have demonstrated for the first time that mutations in FGF9 cause craniosynostosis in humans and confirm that FGF9 mutations cause multiple synostoses. PMID: 28730625 Forced expression of miR-187 inhibited the subcutaneous growth of cervical cancer cells in nude mice. Furthermore, FGF9 was found to be the downstream target of miR-187 in cervical cancer cells. PMID: 28849071 Results show compelling data that homodimerization controls receptor binding specificity of FGF9 by keeping the concentration of active FGF9 monomers at a level, which is sufficient for a normal FGFR "c" isoform binding/signaling, but is insufficient for an illegitimate FGFR "b" isoform. Mutation in FGF9 N or C-terminus skews the ligand equilibrium toward active monomers causing off-target binding and activation of FGFb. PMID: 28757146 The upregulation of FGF9 or the downregulation of miR-372-3p substantially retarded lung squamous cell carcinoma (LSCC) cell growth, mitosis, and invasion. MiR-372-3p enhanced LSCC cell proliferation and invasion through inhibiting FGF9. PMID: 28440022 Data suggest that fibroblast growth factor 9 (FGF9) may provide the anti-apoptotic function and be useful as a novel independent marker for evaluating gastric cancer (GC) prognosis. PMID: 27166269 CCND1 mRNA expression is increased by FGF9 in bovine theca cells and granulosa cells. PMID: 27816766 The present data indicate that non-natural FGFR2 ligands, such as FGF10 and FGF19, are important factors in the pathophysiology of Aspert syndrome. PMID: 27339175 In FGF9-overexpressing colorectal cancer cell lines, FGF9 overexpression induced strong resistance to anti-EGFR therapies via the enforced FGFR signal, and this resistance was cancelled by the application of an FGFR inhibitor. PMID: 26916220 FGF9 and FGF18 increased the migratory capacities of human lung fibroblasts, and FGF9 actively modulated matrix metalloproteinase activity in idiopathic pulmonary fibrosis. PMID: 26773067 we conclude that the S99N mutation in Fgf9 causes multiple synostoses syndrome (SYNS) via the disturbance of joint interzone formation. These results further implicate the crucial role of Fgf9 during embryonic joint development PMID: 28169396 These studies identify FGF9 as a target of DICER1 in lung epithelium that functions as an initiating factor for pleuropulmonary blastoma. PMID: 25978641 Data indicate that expressing either human FGF9 in the kidney subcapsular space of female BALB/c mice yielded rapidly expanding local tumors. PMID: 26183774 FGF9 was strongly expressed in CAFs in comparison with NGFs, being compatible with microarray data indicating that FGF9 was a novel growth factor overexpressed in Cancer-associated fibroblasts PMID: 25925261 the relative levels of FGF9 in relation to other members of the FGF family may prove key to understanding vulnerability or resilience in affective disorders. PMID: 26351673 we found that Kl treatment impairs Nodal mRNA expression and Fgf9-mediated Nanos2 induction, reinforcing the antagonistic effect of these two growth factors on the meiotic fate of male germ cells PMID: 25766327 our data demonstrate that FGF9 can initiate a complex astrocytic response predicted to compromise remyelination, while at the same time stimulating microglial/macrophage recruitment in multiple sclerosis lesions PMID: 25907862 expression is associated with poor prognosis in lung cancer PMID: 24239165 MAP3K1 mutations tilt the balance in the sex-determining pathways by downregulating SOX9 and FGF9. PMID: 24135036 The data demonstrates that FGF9 IRES functions as a cellular switch to turn FGF9 protein synthesis 'on' during hypoxia, a likely mechanism underlying FGF9 overexpression in cancer cells. PMID: 24334956 FGF9 was proved to be a direct target of miR-26a PMID: 24015269 FGF9 can be associated with epithelial-to-mesenchymal transition and invasion by inducing VEGF-A expression in prostate cancer cells. PMID: 24511001 In addition to the role of sex determination, FGF9 is expressed in postnatal Leydig cells and is involved in cell-to-cell interaction of testicular function. Aberrant expression of testicular FGF9 is associated with SCOS. PMID: 24011613 The results demonstrate that FGF9 protein increased in regions of active cellular hyperplasia, metaplasia, and fibrotic expansion of idiopathic pulmonary fibrosis lungs. PMID: 23797050 The importance of Fgf9 in hair follicle regeneration suggests that it could be used therapeutically in humans. PMID: 23727932 neither DMRT1 nor FGF9 abnormalities are frequently involved in dysgenetic male gonad development in patients with non-syndromic 46,XY disorder of sex development. PMID: 22939835 the FGF9(S99N) monomer is preferred to bind with the FGFR3c receptor to form an inactive complex, leading to impaired FGF signaling; the impaired FGF signaling is believed to be a potential cause of synostoses syndrome, implicating an important role for FGF9 in normal joint development PMID: 22920789 These results indicate that FGF9 can stimulate proliferation and invasion in prostate cancer cells, thus FGF9 could be a candidate of a predictive factor for recurrence after radical prostatectomy. PMID: 22006051 Fibroblast growth factor 9 was also overexpressed in all serous ovarian tumors with greater than 1000-fold increase in gene expression in 4 tumors. PMID: 21666490 Microvessels formed in the presence of FGF9 had enhanced capacity to receive flow and were vasoreactive. PMID: 21499246 FGF9 is an autocrine estromedin endometrial stromal growth factor that plays roles in cyclic proliferation of uterine endometrial stroma PMID: 12072406 The capability of proliferation possessed by endometriotic stromal cell during menstruation when ovarian 17 beta-estradiol is in the nadir may be mediated, at least in part, by autocrined estrogen-stimulated expression of FGF-9 and its receptors. PMID: 14602803 Recombinant human FGF-9 signaling enhances the intrinsic osteogenic potential by selectively expanding committed chick embryo osteogenic cell populations as well as inversely regulating bone morphogenetic protein 2 (BMP-2) and noggin gene expression. PMID: 15780951 Mesothelial and epithelial transgenic FGF9 directs lung development by regulating mesenchymal growth, and the pattern and expression levels of mesenchymal growth factors that signal back to the epithelium. PMID: 16540513 Our findings may also provide a molecular framework for considering roles for PGE2 in FGF-9-related embryonic development and/or human diseases. PMID: 16982695 Polymorphic microsatellite in the 3'-UTR of FGF9 in patients with Gonadal dysgenesis.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
