Elevated levels of insulin-like growth factor-I (IGF-I) are associated with carcinogenesis and cancer progression. However, the molecular mechanisms by which IGF-I promotes prostate cancer development remain to be elucidated. Docetaxel chemotherapy is an important therapeutic strategy in many types of human cancers including prostate cancer. In this study, we showed that IGF-I rendered PC-3 and...
Insulin-like growth factor-I (IGF-I) in human hepatoma cells (HEP-G2) has, in addition to its effect on cell growth, short-term metabolic effects acting through its own receptor. We have demonstrated that normal human hepatocytes, compared with HEP-G2 cells, have virtually no IGF-I binding sites. Because the rate of growth is the major difference between the hepatoma and the normal liver, we as...
ABSTRACT Background and Objectives: We studied effects of eight weeks of resistance training and IGF-1 injection on serum level of IGF-1, IGFBP-3 and IGF-1/IGFBP-3 ratio in Wistar rats. Methods: We randomly divided 28 male Wistar rats into four groups of saline-injected control (C), resista...
The insulin-like growth factor I receptor (IGF-IR) belongs to the family of transmembrane tyrosine kinase receptors, like the receptors for platelet-derived growth factor, the epidermal growth factor, insulin, and others. Genetic evidence has shown that the IGF-IR is required for optimal growth in vitro and in vivo. Even more important, however, have been recent findings from several laboratori...
