Androgen receptor expression in hypospadias

Journal of Indian Association of Pediatric Surgeons, 2020
Introduction: The exact mechanism behind the development of hypospadias is unclear. Research studies on androgen receptor (AR) expression are controversial with results stating all possible outcomes – AR elevated, similar, or reduced when compared to ...

Sex Hormones Associate With Amyotrophic Lateral Sclerosis Risk and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Amyotrophic lateral sclerosis (ALS) risk differs by sex and age, implicating sex hormones as potential modifiers. This study examined plasma levels of biologically active sex hormones and their association with ALS odds and survival in cases (females n = 131, males n = 189) and controls (females n = 138, males n = 150) from the University of ...

Proteomic changes in rat spermatogenesis in response to in vivo androgen manipulation; impact on meiotic cells. [PDF]

PLoS ONE, 2012
The production of mature sperm is reliant on androgen action within the testis, and it is well established that androgens act on receptors within the somatic Sertoli cells to stimulate male germ cell development.

Immunolocalization of steroidogenic enzymes in the vaginal mucous of Galea spixii during the estrous cycle. [PDF]

, 2017
BackgroundThe synthesis of sex steroids is controlled by several enzymes such as17α-hydroxylase cytochrome P450 (P450c17) catalyzing androgen synthesis and aromatase cytochrome P450 (P450arom) catalyzing estrogen synthesis, both of which must complex ...

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

Advanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

Gut Bacteria Improve Depressive Symptoms by Degrading Cortisol into Androgen

Advanced Science, EarlyView.
Chronic stress is an important risk factor for stress‐related disorders such as depression. Stress hormone cortisol is essential for the pathogenesis of stress‐related disorders such as depression. Some gut microbiota degraded cortisol, and improve depressive symptoms.
