The present invention relates to a composition or kit of parts comprising an inhibitor of IRS-1 and an inhibitor of the VEGF pathway and to the use thereof for treating an angiogenic disease.

Composition comprising inhibitors of IRS-1 and of VEGF

A method for the treatment of cancers and/or tumors by administration of a polypeptide having the sequence SEQ ID NO:4 or a polypeptide having an amino acid SEQ ID NO Y which, when aligned with SEQ ID N: 4, has (a) a percentage of identical residues over SEQ ID NO: 4 length of at least 50%, and (b) a percentage of identical residues over a amino acid sequence SEQ ID NO Y length of at least 65% or fragments thereof having at least 20 contiguous amino acids.

Anti-tumor drug, medicament, composition, and use thereof

The present invention relates to an inhibitor of the expression of IRS-1 for treating an angiogenic and/or inflammatory skin disease. The present invention also relates to a transdermal composition, preferably an ointment, comprising an inhibitor of the expression of IRS-1, and to the use thereof for treating an angiogenic and/or inflammatory skin disease.

Inhibitor of IRS-1 for treating skin disorders

The present invention relates to peptide from 4 to 50 amino acids comprising a phosphorylated pYXXXmotif (SEQ ID NO: 1), wherein each Xindependently is M or Nle and Xis any amino acid, pharmaceutical compositions comprising said peptide and use thereof for treating cancer.

Peptides for treating cancer

An active polypeptide comprising the amino acid sequence of SEQ ID NO:4, having an anti-tumor activity, and compositions and methods including the active polypeptide.

The present invention relates to an active polypeptide including the amino acid sequence of SEQ ID NO:3, or having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of SEQ ID NO:3, or fragments thereof having at least 21 contiguous amino acids, or peptides having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of the fragments, provided that the polypeptide is not SEQ ID NO:2, variants and antigenic fragments thereof, SEQ ID NO 16 or SEQ ID NO 17, and uses thereof in a method of treating cancer and/or tumours of the human or animal body.

The present invention relates to new peptides, pharmaceutical composition and cosmetic composition including them and their use for wound healing.

Peptides for wound healing

An active polypeptide comprising the amino acid sequence of SEQ ID NO: 3, or having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of SEQ ID NO: 3, or fragments thereof having at least 21 contiguous amino acids, or peptides having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of the fragments, provided that the polypeptide is not SEQ ID NO: 2. A method for inhibiting cancer and/or tumor growth comprising administering to a subject in need thereof an effective amount of the active polypeptide.

Therapeutic compositions used in the field of angiogenesis include nucleotide sequences of genes, the involvement of the genes in the angiogenesis mechanism having been demonstrated by the Applicant, and including the complementary sequences thereof, the antisense sequences of same, polypeptide sequences coded by the coding parts of the aforementioned genes and antibodies that are directed against the polypeptide sequences and also relate to genetically-modified cells that underexpress or overexpress the above-mentioned genes and to therapeutic compositions containing the cells, which are used to treat angiogenic disorders, and, moreover, relate to methods of diagnosing and/or prognosticating antigenic disorders and to novel methods of screening active compounds in the treatment of the disorders.

Composition comprising an antisense sequence implicated in the regulation of angiogenesis

The present invention relates to a wound-treating agent and to a composition for the treatment of wounds comprising a polypeptide having the amino acid sequence of SEQ ID NO:2, or of a polypeptide having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of SEQ ID NO:2.

Wound healing agent and composition

An active polypeptide includes the amino acid sequence of SEQ ID NO:3, or having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of SEQ ID NO:3, or fragments thereof having at least 20 contiguous amino acids, or peptides having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of the fragments, provided that the polypeptide is not SEQ ID NO:2.

Nucleotide sequences and the corresponding polypeptide sequences implicated in the regulation of angiogenesis are identified. The nucleotide and polypeptide sequences, or pharmaceutical compositions made from such sequences, can be used in the clinical study of the angiogenesis process, the prognosis, diagnosis and treatment of pathologies linked to angiogenesis, and in the implementation of pharmacological, pharmacogenomic and drug identification trials.

Composition comprising an angiogenesis related protein

An active polypeptide comprising the amino acid sequence of SEQ ID NO: 3, or having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of SEQ ID NO: 3, or fragments thereof having at least 21 contiguous amino acids, or peptides having at least 50%, preferably 70%, more preferably 90% identity with the amino acid sequence of the fragments, provided that the polypeptide is not SEQ ID NO: 2. A method for inhibiting cancer and/or tumour growth comprising administering to a subject in need thereof an effective amount of the active polypeptide.

The invention relates to therapeutic compositions used in the field of angiogenesis, comprising nucleotide sequences of genes, the involvement of said genes in the angiogenesis mechanism having been demonstrated by the Applicant, and including the complementary sequences thereof, the antisense sequences of same, polypeptide sequences coded by the coding parts of the aforementioned genes and antibodies that are directed against said polypeptide sequences. The invention also relates to genetically-modified cells that underexpress or overexpress the above-mentioned genes and to therapeutic compositions containing said cells, which are used to treat angiogenic disorders. Moreover, the invention relates to methods of diagnosing and/or prognosticating antigenic disorders and to novel methods of screening active compounds in the treatment of said disorders.
