چکیده

3 -hydroxysteroid dehydrogenase (3 -HSD) is known to be involved in steroid production and/or metabolism and to be expressed in many tissues including adrenal cortex. Expression of this enzyme has also been elucidated in human cardiovascular system but its details remain largely unknown. Therefore, in this study, we examined the status of 3 -HSD in postmortem human aorta utilizing RT-PCR and immunohistochemical analysis. Both mRNAs and immunoreactivity for the enzyme were detected predominantly in female aorta, and in those with mild atherosclerotic changes. In addition, immunohistochemical study demonstrated that immunoreactivity for 3 -HSD was detected in vascular smooth muscle cells (VSMCs) of aorta. These findings all indicated that steroidogenesis via 3 -HSD may occur in VSMCs of human aorta, possibly related to gender differences and/or the degree of atherosclerosis.

Synthesis and Molecular Docking Studies of 2-arylideneindan-1,3-diones Derivatives as an Inhibitor of 17β-hydroxysteroid Dehydrogenase Type 1

Due to the drawbacks of applying catalysts in the synthesis of α,β-unsaturated structure units and the importance of these materials, electrochemistry has been introduced as an efficient alternative.Therefore, herein a high-yield synthesis of 2-arylideneindan-1,3-diones is proposed. The procedure is carried out in propanol, using electrons as a green catalyst for generating propanol anion...

Functional adrenocorticotropic hormone receptor in cultured human vascular endothelial cells : possible role in control of blood pressure.

Hypertension is a prominent feature of patients with Cushing's disease and ectopic adrenocorticotropic hormone (ACTH) syndrome, who have elevated ACTH levels. Chronic administration of ACTH (1-24) also raises blood pressure in humans. This effect has been postulated to be due to ACTH-induced increases in cortisol secretion in the adrenal gland. It is well known that cortisol increases vascular ...

Isolation and characterization of novel human short-chain dehydrogenase/reductase SCDR10B which is highly expressed in the brain and acts as hydroxysteroid dehydrogenase.

Hydroxysteroid dehydrogenase belongs to the subfamily of short-chain dehydrogenases/reductases (SDR), and 11-beta-hydroxysteroid dehydrogenase catalyzes the interconversion of inactive glucocorticoids (cortisone in human, dehydrocorticosterone in rodents) and active glucocorticoids (cortisol in human, corticosterone in rodents). We report here the cloning and characterization of a novel human S...

The Effects of Piper Sarmentosum Water Extract on the Expression and Activity of 11β-Hydroxysteroid Dehydrogenase Type 1 in the Bones with Excessive Glucocorticoids

Background: Long-term glucocorticoid therapy causes secondary osteoporosis leading to pathological fractures. Glucocorticoid action in bone is dependant upon the activity of 11β-hydroxysteroid dehydrogenase type 1 enzyme (11β-HSD1). Piper sarmentosum is a local herb that possesses the ability to inhibit 11-βHSD1 enzyme activity. We aimed to determine the effects of Piper sarmentosum wat...
