Traditionally, in women, only the theca cells in the ovary and the zona reticularis layer of the adrenal cortex are believed to synthesize androgens. Interestingly, their neighboring cell layers, the granulosa cells and the zona glomerulosa cells, respectively, do not produce androgens. Recent literature has highlighted the role of the activator protein (AP-1) transcription factor, c-Fos, in the dynamics of this structural and functional relationship. Differential expression of c-Fos is believed to result in distinct patterns of steroidogenesis among these compartments in both the ovary and the adrenal glands. Clinically, deficient c-Fos levels have been implicated in the pathogenesis of polycystic ovary syndrome (PCOS). In this review, we discuss the pivotal role of c-Fos in controlling the expression of CYP17 and hence androgen production in various organ systems throughout the human body.

Background: Endocrine-disrupting chemicals (EDCs) interfere with the endocrine system and negatively impact reproductive health. Biochanin A (BCA), an isoflavone with anti-inflammatory and estrogen-like properties, has been identified as one such EDC. This study investigates the effects of BCA on transcription, metabolism, and hormone regulation in primary human granulosa cells (GCs), with a specific focus on the activation of bitter taste receptors (TAS2Rs).

This study aims to verify the effects of prolonged ingestion of coconut oil on the adrenal glands of Mongolian gerbils. Mongolian gerbils were used as an experimental model due to the morphological similarity of the adrenal glands to those of primates. Male Mongolian gerbils, 3 months of age, were divided into three experimental groups (n = 12): an intact control group, which received no treatment, a gavage control group, which received 0.

Background: Granulosa cell ovarian tumors (GCTs) are a rare neoplasia characterized by a pathognomonic mutation in the FOXL2 gene. In vitro studies have demonstrated an overactivation of hormone activity due to this alteration. Thus, we aimed to determine the activity of orteronel, a CYP17 inhibitor, in advanced disease.

Although the most common cause of congenital adrenal hyperplasia (CAH) worldwide is 21-hydroxylase deficiency (21-OHD), which accounts for more than 95% of cases, other rare causes of CAH such as 11-beta-hydroxylase deficiency (11β-OHD), 3-beta-hydroxy steroid dehydrogenase (3β-HSD) deficiency, 17-hydroxylase deficiency and lipoid CAH (LCAH) may also be encountered in clinical practice. 11β-OHD is the most common type of CAH after 21-OHD, and CYP11B1 deficiency in adrenal steroidogenesis causes the inability to produce cortisol and aldosterone and the excessive production of adrenal androgens. Although the clinical and laboratory features are similar to 21-OHD, findings of mineralocorticoid deficiency are not observed.

Genome editing has the potential to improve growth and traits of aquatic animals. Assessment of the feeding habits of the genetically modified farmed fish is necessary, as this is closely related to the assessment of their growth performance, which is one of the most important economic traits. Previously, we developed a novel strategy to produce all-female (AF) common carp (+/-;XX genotype) with genome editing, which exhibited a growth advantage compared to the control carp (including control male and female carp).
