A transgenic carrier with deal targets (fibroblast growth factor receptor and integrant) is composed of the polypeptide CR16 specifically linked with alkaline fibroblast growth factor receptor, the polypeptide CP9 specifically linked with integrant, and the transgenic non-virus carrier system of CR16/CP9/cationic polymer PEI/exogenous DNA. Said carrier can effectively introduce the exogenous DNA to the tumor cell line and tumor tissue with high expression of FGFRs, so suppressing the growth of tumor. It can be used to preparation of the medicine for treating tumor and other diseases.

[Problems] To provide a technique which enables an effective antibody therapy for cancer which targets for FGFR1 without the need of using any effective antibody having high specificity and a potent cell-killing activity.

[Means for Solving Problems] Disclosed are: a therapeutic agent for cancer, which comprises an enhancer of the expression of a fibroblast growth factor receptor-1 and an anti-fibroblast growth factor receptor-1 antibody; and a method for the treatment of cancer using the therapeutic agent.

Isolated fibroblast growth factor receptor (FGFR5) polypeptides and polynucleotides encoding such polypeptides are provided. Also provided are modulators of FGFR5 gene expression and binding molecules that specifically bind to and agonize or antagonize FGFR5 polypeptide function. Specific binding molecules include antibodies, functional fragments thereof, as well as scFv and Camelidae heavy chain IgG that specifically bind to FGFR5 thereby modulating the activity of FGFR5 and, thus, are effective agents suitable for the treatment of diseases such as osteopontin-mediated autoimmune disease, such as systemic lupus erythematosus, bone disorders including osteoporosis and osteopetrosis, and cancers, including cellular carcinomas such as hepatocellular carcinomas.

The invention discloses a detection chip for a tumor driving gene and application thereof. The detection chip for the tumor driving gene comprises an ALK (anaplastic lymphoma kinase) fusion detection agent, an EGFR (epidermal growth factor receptor) fusion detection agent, an RET (reticulocyte) fusion detection agent and an ROS1 (reactive oxygen species 1) fusion detection agent. Proofed by the results of clinical detect, after fusion probes corresponding to the ALK, the EGFR, the RET and the ROS1 are specifically designed, the detection chip has the advantages that the sensitivity is high, and the gene fusion between a particular site area of the ALK, the EGFR, the RET and the ROS1 and fusion segments is specifically detected. The invention further discloses a detection chip for detecting a second sequence group of the gene mutation and a third sequence group of the gene amplification; after detecting once, the gene fusion, gene mutation and gene amplification of the multiple tumor driving genes, such as the ALK, BRAF (aserine/theroninespecific kinases), DDR2 (discordin domain receptor 2), the EGFR, ERBB2 (receptor tyrosine kinase 2), FGFR1 (fibroblast growth factor receptor 1), KRAS (kirstenrat sarcoma viral oncogene), MET (methionine), NRAS, PIK3CA (phosphatidylino-sitol 3-kinases), the RET and the ROS1.

The present invention relates to various newly identified polynucleotides, polypeptides encoded by such polynucleotides, uses of such polynucleotides and polypeptides, and production of such polynucleotides and polypeptides. More specifically, the polypeptide of the present invention is keratinocyte growth factor, sometimes referred to hereinafter as "KGF-2," and formerly referred to as fibroblast growth factor 12 (FGF-12). The present invention also relates to the therapeutic use of KGF-2 for promoting or accelerating wound healing. The present invention also relates to new mutant forms of KGF-2 which show enhanced activity, increased stability, higher yield or better solubility.

New fibroblast growth factor receptor 1 (FGFR1) inhibitors have been identified which are useful for promoting the retention and/or growth of keratin fibers, such as hair of the scalp, hair of the face (moustache, beard, etc.), eyebrows, eyelashes, and the like. The FGFR1 inhibitors may be formulated in effective amounts in a variety of cosmetic and personal care products.

The invention features soluble fibroblast growth factor receptor 3 (sFGFR3) polypeptides. The invention also features methods of using sFGFR3 polypeptides to treat skeletal growth retardation disorders, such as achondroplasia.

The invention was involved in the polymine modified vector of fibroblast growth factor receptor, containing peptide YC25 which could specially bind to the alkaline fibroblast growth factor receptor, peptide YC25/positive ion PEI/exogenous DNA.The exogenous DNA could be effectively introduced to the cancer clone and system of high expression of FGFRs to inhibit the growth of tumor. But there was low effect to the tumor tissue and cell liens without expression of FGFRs, so the vector system was tumor-targeting. The non-virus vector system could transfer the exogenous DNA and its size ranged from tens bp to thousands kb to overcome the limit of the size of exogenous gene. So, it could be used to produce the medicament to cure tumor by combined transfer of multi-gene and also to produce gene drug for other disease.

The invention discloses a polypeptide with function of promoting the activity of a fibroblast growth factor receptor 3 (FGFR3) and a screening method and an application thereof. The polypeptide is formed by an amino acid sequence shown as Val-Sel-Pro-Pro-Leu-Thr-Leu-Gly-Gln-Leu-Leu-Ser. The screening method comprises the following steps: incubating a bacteriophage 12 peptide library and an elisa plate coated by the FGFR3 together, washing non-specificity combined bacteriophage, then eluting specificity combined bacteriophage and amplifying to be used as input bacteriophage elutriated in the next turn, repeating the steps for performing elutriations in three turns, extracting DNA singly cloned by the bacteriophage elutriated in the third turn and sequencing, deducting the amino acid sequence of a foreign polypeptide shown on the bacteriophage, synthesizing the polypeptide, detecting the promotion of the polypeptide to the activity of the FGFR3, and obtaining the polypeptide with function of promoting the activity of the FGFR3. The polypeptide can be used for preparing medicine of resisting low FGFR3 function low diseases.
