The Aromatase–Estrogen System in the Testes of Non-Mammalian Vertebrates

open access: yesAnimals, 2021
Estrogens are important physiological regulators of testicular activity in vertebrates. Estrogen levels depend on the activity of P450 aromatase, the enzyme responsible for the irreversible conversion of testosterone into 17β-estradiol.

Preparation of a novel antiserum to aromatase with high affinity and specificity: Its clinicopathological significance on breast cancer tissue. [PDF]

open access: yesPLoS ONE, 2017
Aromatase inhibitors have been widely used for the endocrine treatment of estrogen-dependent breast cancer in postmenopausal patients. However, clinicopathological studies of aromatase have been limited due to unsatisfactory specificity and/or restricted

Epitope characterization of an aromatase monoclonal antibody suitable for the assessment of intratumoral aromatase activity. [PDF]

open access: yesPLoS ONE, 2009
Immunohistochemistry is one of the most suitable methods for the detection of intratumoral aromatase in order to identify patients who may respond to aromatase inhibitor therapy in hormone-dependent breast cancer.

Quantitative analysis of long-form aromatase mRNA in the male and female rat brain. [PDF]

open access: yesPLoS ONE, 2014
In vitro studies show that estrogens acutely modulate synaptic function in both sexes. These acute effects may be mediated in vivo by estrogens synthesized within the brain, which could fluctuate more rapidly than circulating estrogens.

The HeyL-Aromatase Axis Promotes Cancer Stem Cell Properties by Endogenous Estrogen-Induced Autophagy in Castration-Resistant Prostate Cancer

open access: yesFrontiers in Oncology, 2022
Treatment of patients with castration-resistant prostate cancer (CRPC) remains a major clinical challenge. We previously showed that estrogenic effects contribute to CRPC progression and are primarily caused by the increased endogenous estradiol produced

Effects of Ventromedial Hypothalamic Nucleus (VMN) Aromatase Gene Knockdown on VMN Glycogen Metabolism and Glucoregulatory Neurotransmission

open access: yesBiology, 2023
The enzyme aromatase is expressed at high levels in the ventromedial hypothalamic nucleus (VMN), a principal component of the brain gluco-regulatory network.

Estrogens: a new player in spermatogenesis.

open access: yesFolia Histochemica et Cytobiologica, 2008
The mammalian testis serves two main functions: production of spermatozoa and synthesis of steroids; among them, estrogens are the end products obtained from the irreversible transformation of androgens by aromatase.

Computational method for aromatase-related proteins using machine learning approach.

open access: yesPLoS ONE, 2023
Human aromatase enzyme is a microsomal cytochrome P450 and catalyzes aromatization of androgens into estrogens during steroidogenesis. For breast cancer therapy, third-generation aromatase inhibitors (AIs) have proven to be effective; however patients ...

Potential utility of natural products as regulators of breast cancer-associated aromatase promoters

open access: yesReproductive Biology and Endocrinology, 2011
Aromatase, the key enzyme in estrogen biosynthesis, converts androstenedione to estrone and testosterone to estradiol. The enzyme is expressed in various tissues such as ovary, placenta, bone, brain, skin, and adipose tissue.

PET imaging of brain aromatase in humans and rhesus monkeys by 11C-labeled cetrozole analogs

open access: yesScientific Reports, 2021
Aromatase is an estrogen synthetic enzyme that plays important roles in brain functions. To quantify aromatase expression in the brain by positron emission tomography (PET), we had previously developed [11C]cetrozole, which showed high specificity and ...
