Front Cardiovasc Med 2023; 10:1114528. [PMID: 37113701 PMCID: PMC10126378 DOI: 10.3389/fcvm.2023.1114528] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Accepted: 03/14/2023] [Indexed: 04/29/2023] Open
Abstract
Introduction Vascular calcification (VC) is more likely to be detected in the chronic kidney disease (CKD) population. The mechanism of VC development from CKD is different from that for simple VC and has always been a major research area. The aim of this study was to detect alterations in the metabolome during development of VC in CKD and to identify the critical metabolic pathways and metabolites involved in its pathogenesis. Methods Rats in the model group were given an adenine gavage combined with a high-phosphorus diet to imitate VC in CKD. The aorta calcium content was measured and used to divide the model group into a VC group and non-vascular calcification group (non-VC group). The control group was fed a normal rat diet and given a saline gavage. Ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS) was used to determine the altered serum metabolome in the control, VC, and non-VC groups. The identified metabolites were mapped into the Kyoto Encyclopedia of Genes and Genomes (KEGG) database (https://www.genome.jp/kegg/) for pathway and network analyses. Result There were 14 metabolites that changed significantly in the VC group, with three metabolic pathways playing critical roles in the pathogenesis of VC in CKD: steroid hormone biosynthesis; valine, leucine and isoleucine biosynthesis; and pantothenate and CoA biosynthesis. Conclusion Our results indicated changes in the expression of steroid sulfatase and estrogen sulfotransferase, and down-regulation of the in situ synthesis of estrogens in the VC group. In conclusion, the serum metabolome alters significantly during the pathogenesis of VC in CKD. The key pathways, metabolites, and enzymes we identified are worth further study and may become a promising therapeutic target for the treatment of VC in CKD.

Intracrine Regulation of Estrogen and Other Sex Steroid Levels in Endometrium and Non-gynecological Tissues; Pathology, Physiology, and Drug Discovery. Front Pharmacol 2018; 9:940.

Abstract
Our understanding of the intracrine (or local) regulation of estrogen and other steroid synthesis and degradation expanded in the last decades, also thanks to recent technological advances in chromatography mass-spectrometry. Estrogen responsive tissues and organs are not passive receivers of the pool of steroids present in the blood but they can actively modify the intra-tissue steroid concentrations. This allows fine-tuning the exposure of responsive tissues and organs to estrogens and other steroids in order to best respond to the physiological needs of each specific organ. Deviations in such intracrine control can lead to unbalanced steroid hormone exposure and disturbances. Through a systematic bibliographic search on the expression of the intracrine enzymes in various tissues, this review gives an up-to-date view of the intracrine estrogen metabolisms, and to a lesser extent that of progestogens and androgens, in the lower female genital tract, including the physiological control of endometrial functions, receptivity, menopausal status and related pathological conditions. An overview of the intracrine regulation in extra gynecological tissues such as the lungs, gastrointestinal tract, brain, colon and bone is given. Current therapeutic approaches aimed at interfering with these metabolisms and future perspectives are discussed.

Abstract
Steroid sulfatase (STS) converts sulfated steroids into active forms in cells. Preosteoblastic cells possess STS, but its role and regulation in bone are unclear. We examined STS activity and gene expression during differentiation of human MG-63 preosteoblasts. STS activity and gene expression were decreased during differentiation in cells treated with osteogenic supplement containing dexamethasone (DEX). DEX also inhibited STS activity and expression in undifferentiated cells, and the glucocorticoid antagonist RU486 reversed DEX inhibition of STS. These data may have implications for glucocorticoid-induced osteoporosis. The NFκB activators lipopolysaccharide and phorbol myristate acetate increased STS expression in undifferentiated and differentiated MG-63 cells, while the NFκB inhibitor BAY-11-7082 partially blocked these responses. The antagonistic actions of glucocorticoids and NFkB on STS expression are similar to the regulation of inflammatory response proteins. We propose a model of STS regulation whereby inflammation leads to increased STS, resulting in increased estrogen, which modulates the inflammatory response.

Int J Mol Med 2015; 36:1572-82. [PMID: 26496941 PMCID: PMC4678161 DOI: 10.3892/ijmm.2015.2382] [Citation(s) in RCA: 16] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2015] [Accepted: 10/13/2015] [Indexed: 01/10/2023] Open
Abstract
Both β-catenin (β-cat) and osterix (OSX) are known to be essential for embryonic and postnatal osteoblast differentiation and bone growth. In the present study, we explored the crosstalk between β-cat signaling and OSX, and assessed its effect on the osteoblastogenic differentiation of human pre-osteoblastic cells (MG-63) and bone marrow stromal cells (HS-27A). In the HS-27A and MG-63 cells, the selective β-cat signaling inhibitor, CCT031374, and the stable overexpression of a constitutively active β-cat mutant respectively decreased and increased the cytoplasmic/soluble β-cat levels, and respectively decreased and increased TOPflash reporter activity, the mRNA levels of β-cat signaling target genes c-Myc and c-Jun, as well as the mRNA and protein expression levels of OSX. Mutational analyses and electrophoretic mobility shift assays revealed that the increased binding activity of c-Jun at a putative c-Jun binding site (-858/-852 relative to the translation start codon, which was designated as +1) in the human OSX gene promoter was required for teh β-cat signaling-induced expression of OSX in the HS-27A and MG-63 cells. During osteoblastogenic culture, stimulating β-cat signaling activity by the stable overexpression of the active β-cat mutant markedly increased alkaline phosphatase (ALP) activity and calcium deposition in the HS-27A and MG-63 cells, which was abolished by knocking down OSX using shRNA. On the other hand, the inhibition of β-cat signaling activity with CCT031374 decreased the ALP activity and calcium deposition, which was completely reversed by the overexpression of OSX. On the whole, the findings of our study suggest that β-cat signaling upregulates the expression of OSX in human pre-osteoblastic and bone marrow stromal cells by trans-activating the OSX gene promoter mainly through increased c-Jun binding at a putative c-Jun binding site; OSX largely mediates β-cat signaling-induced osteoblastogenic differentiation. The present study provides new insight into the molecular mechanisms underlying osteoblast differentiation.

Abstract
In 1994, following work from this laboratory, it was reported that estrone-3-O-sulfamate irreversibly inhibits a new potential hormone-dependent cancer target steroid sulfatase (STS). Subsequent drug discovery projects were initiated to develop the core aryl O-sulfamate pharmacophore that, over some 20 years, have led to steroidal and nonsteroidal drugs in numerous preclinical and clinical trials, with promising results in oncology and women's health, including endometriosis. Drugs have been designed to inhibit STS, e.g., Irosustat, as innovative dual-targeting aromatase-steroid sulfatase inhibitors (DASIs) and as multitargeting agents for hormone-independent tumors, such as the steroidal STX140 and nonsteroidal counterparts, acting inter alia through microtubule disruption. The aryl sulfamate pharmacophore is highly versatile, operating via three distinct mechanisms of action, and imbues attractive pharmaceutical properties. This Perspective gives a personal view of the work leading both to the therapeutic concepts and these drugs, their current status, and how they might develop in the future.
