BINDING OF RADIOGRAPHIC CONTRAST MEDIA TO SERUM PROTEINS A clinical and experimental investigation of their adverse effects through influence on active steroid hormone levels. by Staffan Wirell, M.D., Department of Diagnostic Radiology, University Hospital of Umeå, S-901 85 Umeå, Sweden. Summary of thesis based on the following papers: I Wirell S.: Adverse reactions at intravenous cholegraphy w...
We describe a cytoplasmic steroid binding protein in the chick oviduct which has intriguing characteristics. This protein binds [3H]estradiol with high affinity (Kd = 30 X 10(-9) M) and limited capacity (300 fmol/mg of cytosol protein). It sediments at 8 S in low-salt sucrose density gradients and at 4 S in high-salt gradients. Unlike the estrogen receptor, however, this protein also binds prog...
Regucalcin (RGN) is a mammalian Ca2+-binding protein that plays an important role in intracellular Ca2+ homeostasis. Recently, RGN has been identified as a target gene for sex steroid hormones in the prostate glands and testis of rats and humans, but no studies have focused on RGN expression in bovine tissues. Thus, in the present study, we examined RGN mRNA and protein expression in the differ...
Sex hormone-binding globulin (SHBG) is the high-affinity binding protein for androgens and estrogens. According to the free hormone hypothesis, SHBG modulates the bioactivity of sex steroids by limiting their diffusion into target tissues. Still, the in vivo physiological role of circulating SHBG remains unclear, especially since mice and rats lack circulating SHBG post-natally. To test the fre...
The site-directed photoaffinity ligand [3H]17 beta-hydroxy-4,6-androstadien-3-one (delta 6-testosterone) was used to label the steroid binding domain of rat androgen-binding protein (rABP). After digestion with trypsin, the major radiolabeled peptide was isolated by reverse phase chromatography. The peptide was found to have the following amino acid sequence: Ile Ala Leu Gly Gly Leu Leu Leu Pro...
