  • Patent number: 8735061
    Abstract: There is provided a method for determining tumour metastatic potential using biomarkers of tumour metastasis comprising any two of carbonic anhydrase-9 (CAIX), vascular endothelial growth factor C (VEGF-C), ephrin A5 (EFNA5), eph receptor B2 (EPHB2), transforming growth factor beta 3 (TGF-?3), pyruvate dehydrogenase kinase isoenzyme-3 (PDK3), carbonic anhydrase-12 (CAXII), keratin 14 (KRT14), hypoxia inducible factor 1 alpha subunit (HIF-1?), and tenascin C (TNC). CAIX, VEGF-C, EFNA5, EPHB2, TGF-?3 or PDK3 may be indicators of moderate metastatic potential, while CAXII, KRT14, HIF-1?, or TNC may be indicators of high metastatic potential. The biomarkers may be used to assess malignancies or cancers having hypoxic regions, such as breast cancer.

  • Publication number: 20030060613
    Abstract: This invention relates to isolated and purified proteins, such as calreticulin and mimetics of calreticulin, for a novel use of modulating hormone responsiveness. These proteins are useful in gene therapy and in manufacturing pharmaceuticals for treating a variety of diseases, including cancer, osteoporosis and chronic inflammatory disease. The proteins include or bind to an amino acid sequence KXFFYR, wherein X is either G, A or V and Y is either K or R. This sequence is present in the DNA-binding domain, and is critical for the DNA binding activity, of a variety of hormone receptors, including glucocorticoid receptor, minerolcorticoid receptor, androgen receptor, progesterone receptor, estrogen receptor, retinoic acid receptor, thyroid hormone receptor and vitamin D receptor. Proteins which bind to this sequence may inhibit hormone receptor induced gene transcription. Proteins which include this sequence may promote hormone receptor induced gene transcription.
