The present invention relates to the use of Fibroblast Growth Factor Receptor I (FGFR1) extracellular domain (ECD) polypeptides for treatment of cancers characterized by ligand dependent activating mutations in Fibroblast Growth Factor Receptor 2 (FGFR2). For example, the present invention relates to the treatment of endometrial cancers and other cancers wherein tumor cells express FGFR2 mutants in the IgII-IgIII hinge region or IgIII domain of the protein, such as at amino acid positions 252 and / or 253.

The present invention provides a combination of an antibody binding to a fibroblast growth factor receptor, and another agent.

Antisense compounds, compositions and methods are provided for modulating the expression of fibroblast growth factor receptor 4 (FGFR4). The compositions comprise antisense compounds, particularly antisense oligonucleotides, targeted to nucleic acids encoding fibroblast growth factor receptor 4. Methods of using these compounds for modulation of fibroblast growth factor receptor 4 expression and for treatment of diseases associated with expression of fibroblast growth factor receptor 4 are provided.

The invention discloses a serum-free medium for culturing placenta mesenchymal stem cells. The serum-free medium takes a DMEM (Dulbecco Modified Eagle Medium) culture solution as a basis and also contains a fibroblast growth factor receptor 2, growth hormone, insulin, transferrin, glutathione, BMP-4, L-glutamine, sodium pyruvate, non-essential amino acids and beta-mercaptoethanol. According to various serum-free media provided by the invention, growth and proliferation of the placenta mesenchymal stem cells in a serum-free medium system can be effectively promoted, the placenta mesenchymal stem cells have higher growth and proliferation rate in the serum-free medium system compared with a serum cell culture medium, the characteristics of the stem cells are preserved, the serum-free medium has multiple differential potentials, and the stem cells can be directionally induced into fat cells and osteoblasts.

Glycosylphosphatidylinositol-(GPI-) anchored HSPG glypican-1 is strongly expressed in human breast and pancreatic cancer—both by the cancer cells and in the case of pancreatic cancer the adjacent fibroblasts—whereas expression of glypican-1 is low in the normal pancreas and in chronic pancreatitis. Treatment of two pancreatic cancer cell lines, which express glypican-1, with the enzyme phosphoinositide-specific phospholipase-C (PI-PLC) abrogated their mitogenic responses to two heparin-binding growth factors: fibroblast growth factor-2 (FGF2) and heparin-binding EGF-like growth factor (HB-EGF). Treatment of MDA-MB-231 and MDA-MB-468 breast cancer cells with PI-PLC abrogates the mitogenic response to two heparin-binding growth factors, heparin-binding epidermal growth factor-like growth factor (HB-EGF) and fibroblast growth factor-2 (FGF-2). Syndecan-1 is also expressed at high levels in breast cancer tissues as well as breast cancer cells by comparison with breast normal tissues. Temporary or permanent transfection of a glypican-1 antisense construct attenuated glypican-1 protein levels and the mitogenic response to FGF2 and HB-EGF. Glypican can be used to detect the carcinoma in vitro and therapeutics that either bind to (e.g., antibodies or drugs), remove (e.g., enzymes) or prevent the expression (e.g., antisense constructs) of surface of the extracellular domain of glypican-1 are effective in retarding the growth of glypican-responsive carcinomas.

The present invention relates to bispecific compounds, compositions, and methods for treating diseases or conditions characterized or mediated by aberrant fibroblast growth factor receptor 2 (FGFR2) activity.

The present invention relates to a therapeutic agent represented by the General formula (I), or a pharmacologically acceptable salt thereof, or a solvate of the compound or the salt thereof:The therapeutic agent comprises a substance having the activity of inhibiting kinase activity of fibroblast growth factor receptor 2 (“FGFR2”). The therapeutic agent can be used for treating undifferentiated gastric cancer, and can also be used to treat organisms comprising a cell overexpressing FGFR2 or a cell expressing mutant FGFR2, or both. The present invention further relates to a pharmaceutical composition comprising an FGFR2 inhibitory and methods of treatment therewith. The present invention also relates to a method for predicting the effect of an FGFR2 inhibitory substance on a patient.

An indole derivative as expressed by Formula (I), a preparation method thereof, a pharmaceutical salt, and use thereof as a therapeutic agent, especially as a FGFR inhibitor. Each substituent in Formula (I) has identical definition as specified in the specification.
