[Problem] To provide a novel nucleic acid aptamer for a vascular endothelial growth factor receptor, said nucleic acid aptamer being useful for the diagnosis and treatment of various diseases associated with VEGFs that can regulate angiogenesis and receptors for the VEGFs, e.g., tumor angiogenesis, diabetic retina and chronic rheumatoid arthritis. [Solution] A nucleic acid aptamer characterized by comprising a nucleotide sequence represented by any one of SEQ ID NOs: 1 to 5, and also characterized by being capable of bonding to a human VEGF receptor specifically. In a preferred embodiment of the nucleic acid aptamer, a primer recognition sequence, a fluorescent label, or a biotin molecule, an avidin molecule, a streptavidin molecule or other specific binding tag peptide may be linked to the 5- or 3-terminal of the nucleic acid aptamer for the purpose of making it possible to detect the nucleic acid aptamer easily.

The present invention relates to methods for modulating angiogenesis, comprising administering to a subject, or cells or tissue derived therefrom: (i) one or more miRNA, or precursors or variants thereof, wherein at least one of said miRNA comprises a seed region comprising the sequence UCACAGU (SEQ ID N0:37) to inhibit angiogenesis; or (ii) one or more antagonists of a miRNA, wherein said miRNA comprises a seed region comprising the sequence UCACAGU (SEQ ID N0:37) to promote or induce angiogenesis. Also provided are methods of diagnosis of conditions associated with abnormal angiogenesis, or determining predisposition thereto. Suitable pharmaceutical compositions are also provided.

This present invention relates to compounds (e.g., TM4SF1 binding proteins, e.g., anti-TM4SF1 antibodies) that specifically bind to a polypeptide at an epitope including an amino acid sequence of SEQ ID NO: 1. In particular, the compounds of the invention are capable of being internalized into a TM4SF1-expressing cell (e.g., a tumor cell or an angiogenic vasculature endothelial cell) following binding to the epitope of including the amino acid sequence of SEQ ID NO: 1. The invention also provides methods of treating a subject having a disorder associated with pathological angiogenesis with the compounds of the invention.

The present invention in various aspects and embodiments involves pharmaceutical compositions of peptides derived from the 5 fibril of type IV collagen, and uses thereof for medical treatment. The peptides target 51 and V3 integrins, and inhibit signaling through multiple receptors, and find use for inhibiting vascular permeability, angiogenesis, lymphangiogenesis.

The present invention provides a pharmaceutical composition for preventing or treating angiogenic diseases comprising inhibitors of NUP153 gene expression or NUP153 activity as active ingredient and a method for screening an agent for preventing or treating angiogenic diseases. According to the present invention, inhibition of the NUP153 gene expression or the NUP153 activity reduces export of mRNA of a pro-angiogenic factor (VEGF, HGF and bFGF) from nucleus. In addition, inhibition of the NUP153 gene expression or the NUP153 activity has effect that angiogenesis are inhibited by inhibition of invasion and tube formation in a dose-dependent manner without showing toxicity. Therefore, the pharmaceutical composition of the present invention may be used for preventing or treating a variety of angiogenesis-related diseases, and the method for screening of the present invention may be valuably used in finding a new agent for preventing or treating angiogenic diseases.

The invention includes, in part, methods and compounds for treating diseases and conditions characterized by elevated threonyl-tRNA synthetase (TARS) activity, which include, but are not limited to diseases and conditions in which angiogenesis is elevated as compared to normal. In some embodiments of the invention, a level of a TARS molecule is determined and compared to a control level of TARS to assess a treatment for a disease or condition characterized by elevated TARS activity.

The present disclosure is generally directed to antibodies, e.g., monoclonal, antibodies, antibody fragments, etc., that specifically bind a MerTK polypeptide, e.g. a mammalian MerTK or human MerTK, and use of such compositions in preventing, reducing risk, or treating a disease or disorder an individual in need thereof.

A method for screening a patient for angioinhibition resistance and treating said patient having a disease susceptible to treatment via an anti-angiogenic agent. The screening method includes an assay for identifying the presence of angioinhibition resistance in patients by collecting patient blood or serum and subjecting it to a Chick Chorioallantoic Membrane (CAM) angiogenesis assay configured for accepting a human tumor wherein the human tumor xenograft includes a vasculature system. The screening method and assay further includes steps that include using the CAM results for identifying the endogenous pro-angiogenic non-peptide hormone concentrations of the blood sample by calculating the vascular activity of the vasculature system of the human tumor xenograft in the presence of anti-angiogenic drugs and inducing in the patient, a state of subclinical hypothyroidism prior to commencing anti-angiogenic treatment.

The present invention relates to a method of identifying cancer subjects, in particular human patients, who are suitable for anti-lymphangiogenesis therapy to prevent tumor growth and tumor metastasis. The present invention also relates to a new approach, which uses nucleolin as a bait to search and screen for lymphangiogenesis inhibitors or cancer suppressors, which function in a manner that is analogous to endostatin. The invention is based upon the discovery that nucleolin is specifically expressed on lymphangiogenic vessels and functions as a specific receptor for endostatin, and thus is involved in the signal transduction pathway of endostatin as an anti-lymphangiogenesis inhibitor. The present invention also discloses that cell surface nucleolin on lymphatic endothelial cells is a biomarker for lymphangiogenic vessels, which could be used for the prediction of tumor metastasis.

The invention relates to compositions and methods for reducing excessive vascular development and treat related disorders. In one aspect, the invention provides methods for treating, reducing or inhibiting vascular development in a subject in need thereof. The methods of the invention comprises administering to the subject an effective amount of a HK2 depleting agent that decreases the level of expression and/or activity of HK2. In some embodiments, the level of expression and/or activity of fibroblast growth factor receptor (FGFR), FGF ligand and/or FGF signaling is/are decreased. The invention also includes methods for diagnosing excessive vascular development and for measuring the efficacy of a treatment for an excessive vascular development in a subject in need thereof. The invention further includes a pharmaceutical composition for treating or reducing angiogenesis or lymphangiogenesis, comprising a HK2 depleting agent and a pharmaceutical acceptable carrier.
