Abstract
Dehydroepiandrosterone (DHEA), a precursor of steroid sex hormones, is synthesized by steroid 17-alpha-hydroxylase/17,20-lyase (CYP17A1) with the participation of microsomal cytochrome b5 (CYB5A) and cytochrome P450 reductase (CPR), followed by sulfation by two cytosolic sulfotransferases, SULT1E1 and SULT2A1, for storage and transport to tissues in which its synthesis is not available. The involvement of CYP17A1 and SULTs in these successive reactions led us to consider the possible interaction of SULTs with DHEA-producing CYP17A1 and its redox partners. Text mining analysis, protein-protein network analysis, and gene co-expression analysis were performed to determine the relationships between SULTs and microsomal CYP isoforms. For the first time, using surface plasmon resonance, we detected interactions between CYP17A1 and SULT2A1 or SULT1E1. SULTs also interacted with CYB5A and CPR. The interaction parameters of SULT2A1/CYP17A1 and SULT2A1/CYB5A complexes seemed to be modulated by 3'-phosphoadenosine-5'-phosphosulfate (PAPS). Affinity purification, combined with mass spectrometry (AP-MS), allowed us to identify a spectrum of SULT1E1 potential protein partners, including CYB5A. We showed that the enzymatic activity of SULTs increased in the presence of only CYP17A1 or CYP17A1 and CYB5A mixture. The structures of CYP17A1/SULT1E1 and CYB5A/SULT1E1 complexes were predicted. Our data provide novel fundamental information about the organization of microsomal CYP-dependent macromolecular complexes.

Abstract
Macrophage proliferation is known to correlate with macrophage accumulation in atherosclerotic plaque, and therefore its inhibition and secondary reduction of plaque inflammation may have therapeutic beneficial effects on atherosclerosis. Recently, we reported that a peptide corresponding to positions 41-51 of royalisin (which consists of 51 amino acid residues), a potent antibacterial protein contained in royal jelly (RJ), can specifically bind to oxidized LDL (Ox-LDL), a major components of atherosclerotic lesions. Here, we investigated the interaction of RJ proteins including royalisin with LDL and Ox-LDL. Measurement of LDL oxidation by the production of thiobarbituric acid reactive substances and conjugated dienes, and by electrophoretic mobility on polyacrylamide gel electrophoresis showed that RJ proteins including royalisin and the degradation products of major RJ protein (MRJP) 1 and MRJP3 can induce oxidation of LDL and Ox-LDL. Surface plasmon resonance experiments showed that these RJ proteins can exhibit much higher binding affinity to LDL than Ox-LDL (the equilibrium dissociation constant, KD = 8.35 and 49.65 μg proteins/mL for LDL and Ox-LDL, respectively). Experiments using cultured mouse J774A.1 macrophage cells proved that these RJ proteins can inhibit macrophage proliferation markedly and concentration-dependently, regardless of the absence or presence of LDL and Ox-LDL, but hardly affect lipid accumulation in macrophages. These results suggest that RJ proteins including royalisin and degradation products of MRJP1/MRJP3 may have therapeutic beneficial effects on atherosclerosis owing to the reduction of plaque inflammation. Further studies of these RJ proteins may lead to the discovery of novel anti-atherosclerotic drugs.

Abstract
Cytosolic estrogen sulfotransferase (SULT1E) mainly catalyzes the sulfate conjugation of estrogens, which decrease atherosclerosis progression. Recently we reported that a YKEG sequence in human SULT1E1 (hSULT1E1) corresponding to residues 61-64 can bind specifically to oxidized low-density lipoprotein (Ox-LDL), which plays a major role in the pathogenesis of atherosclerosis; its major oxidative lipid component lysophosphatidylcholine (LPC), and its structurally similar lipid, platelet-activating factor (PAF). In this study, we investigated the effect of Ox-LDL on the sulfating activity of hSULT1E1. In vivo experiments using a mouse model of atherosclerosis showed that the protein expression of SULT1E1 was higher in the aorta of mice with atherosclerosis compared with that in control animals. Results from a sulfating activity assay of hSULT1E1 using 1-hydroxypyrene as the substrate demonstrated that Ox-LDL, LPC, and PAF markedly decreased the sulfating activity of hSULT1E1, whereas native LDL and 1-palmitoyl-2-(5'-oxo-valeroyl)-sn-glycero-3-phosphocholine (POVPC) as one of the oxidized phosphatidylcholines showed the opposite effect. The sulfating activity greatly changed in the presence of LPC, PAF, and POVPC in their concentration-dependen manner (especially above their critical micelle concentrations). Moreover, Ox-LDL specifically recognized dimeric hSULT1E1. These results suggest that the effects of Ox-LDL and native LDL on the sulfating activity of hSULT1E1 might be helpful in elucidating the novel mechanism underlying the pathogenesis of atherosclerosis, involving the relationship between estrogen metabolism, LDL, and Ox-LDL.
