A method of treating a subject comprising:

• obtaining a therapeutically sufficient amount of a peptide from 4 to 50 amino acids comprising a phosphorylated pYX1X2X1 motif (SEQ ID NO:
• 1), wherein each X1 independently is M or Nle and X2 is any amino acid;
• and
• administering the amount of peptide to the subject;
• wherein a cancer and/or an angiogenesis-related disease is treated in the subject.
