Abstract: Disclosed is a method for searching, identifying, or validating a marker CACNA2D1 of tumor-initiating cells. The method comprises a step of immunizing an animal using HEP-12 cells originating from a recurrent tumor and rich in originating cells. Also disclosed is a monoclonal antibody specially recognizing CACNA2D1 or antigen-binding fragments thereof, and the use thereof for treating or preventing tumors or diseases or conditions related to CACNA2D1.

Abstract: Provided in the present invention are a method using in vitro measurement of the content of methylation or demethylation of GFRa1 CpG islands to estimate a risk of tumorigenesis and of tumor metastasis, or postoperative life expectancy, and a nucleotide sequence used.

Abstract: The invention provides a primer group for detecting CpG island methylation of p16 gene using methylation specific fluorescence technique. The primer group comprises a pair of oligonucleotide primers and a fluorescence-labeled probe. Said oligonucleotide primer pair has base sequence represented by SEQ ID NO.1 and SEQ ID NO.2. Said fluorescence-labeled probe has base sequence represented by SEQ ID NO.3 or SEQ NO.4.

Abstract: Provided in the present invention are a method using in vitro measurement of the content of methylation or demethylation of GFRal CpG islands to estimate a risk of tumorigenesis and of tumor metastasis, or postoperative life expectancy, and a nucleotide sequence used.

Abstract: The invention provides a primer group for detecting CpO island methylation of p16 gene using methylation specific fluorescence technique. The primer group comprises a pair of oligonucleotide primers and a fluorescence-labeled probe. Said oligonucleotide primer pair has base sequence represented by SEQ ID NO.1 and SEQ ID NO.2. Said fluorescence-labeled probe has base sequence represented by SEQ ID NO.3 or SEQ NO.4.

Abstract: The present invention relates to a peptide for anti-angiogenesis and use thereof, in particular, to a peptide useful for treating angiogenesis diseases; a polynucleotide coding the peptide; a vector and a cell comprising the polynucleotide; a pharmaceutical composition comprising the peptide, the fused peptide or the fused protein, the polynucleotide, the vector and/or the cell. The peptide, the fused peptide or the fused protein, the polynucleotide, the vector, the cell and/or the pharmaceutical composition can be used for treatment of associated diseases such as tumor by anti-angiogenesis.

Abstract: The present invention relates to a small peptide for anti-angiogenesis and use thereof, in particular, to a small peptide useful for treating angiogenesis diseases; a polynucleotide coding the peptide; a vector and a cell comprising the polynucleotide; a pharmaceutical composition comprising the small peptide, the fused peptide or the fused protein, the polynucleotide, the vector and/or the cell. The small peptide, the fused peptide or the fused protein, the polynucleotide, the vector, the cell and/or the pharmaceutical composition can be used for treatment of associated diseases such as tumor by anti-angiogenesis.

Abstract: The present invention provides a polypeptide or a pharmacologically acceptable salt thereof comprising one or more, identical or different, amino acid sequences of A-W—H—X1-D-X2-X3-X4-W—W—X5-X6-X7-X8-B (the meaning of each symbol in the formula is defined in the description) and a pharmaceutical composition for treating an angiogenic disease such as a solid tumor comprising said polypeptide. The present invention also relates to a polynucleotide encoding the above-mentioned polypeptide and use of the polynucleotide in gene therapy.
