Tiivistelmä
Hormonal cancers such as breast and prostate cancer arise from steroid hormone-regulated tissues. In addition to breast and prostate cancer hormonal regulation has also a role in endometrial, ovarian, testis and thyroid carcinomas. The effects of estrogens, androgens and progestagens on tumor growth are largely mediated by paracrine and autocrine target molecules which include growth factors and growth factor receptors. During cancer progression the hormonal growth regulation is often lost or overcome by an inappropriate activation of growth factor signaling cascades. One of the growth factors which have been associated with the regulation of growth and progression of hormonal cancer is fibroblast growth factor 8 (FGF8) which has also been recognized as an oncogene. FGF8 is widely expressed during embryonic development. It has been shown to mediate embryonic epithelial-mesenchymal transition and to have a crucial role in gastrulation and early organization and differentiation of midbrain/hindbrain, pharyngeal, cardiac, urogenital and limb structures. During adulthood FGF8 expression is much more restricted but in hormonal cancers it becomes frequently activated. High level of FGF8 expression in tumors is associated with a poor prognosis at least in prostate cancer. In experimental models FGF8 induces and facilitates prostate tumorigenesis and increases growth and angiogenesis of tumors. Several lines of evidence for autocrine and paracrine loops in the growth regulation of breast, prostate and ovarian cancer by FGF8 have been suggested.
