30-60 / 1000+ results research Neonatal neurosteroid levels are determinant in shaping adult prepulse inhibition response to hippocampal allopregnanolone in rats
Neonatal neurosteroid levels affect adult brain function and behavior.
research Relating neurosteroid modulation of inhibitory neurotransmission to behaviour
Neurosteroids can influence behavior by modulating brain inhibition, with potential for treating psychiatric disorders.
research Chronic progesterone treatment augments while dehydroepiandrosterone sulphate prevents tolerance to ethanol anxiolysis and withdrawal anxiety in rats
Progesterone increases alcohol tolerance and withdrawal anxiety, while DHEAS prevents them.
research PR-independent neurosteroid regulation of α2-GABA-A receptors in the hippocampus subfields
Progesterone and its byproducts control a specific receptor in the brain independently of progesterone receptors, affecting conditions related to the menstrual cycle.
research Allopregnanolone mediates the exacerbation of Tourette-like responses by acute stress in mouse models
Stress worsens Tourette symptoms by increasing allopregnanolone levels.
research Effect of Neurosteroids on Basal and Stress-Induced Oxytocin Secretion in Luteal-Phase and Pregnant Sheep
Neurosteroids help regulate oxytocin levels, especially during stress and pregnancy, to protect against premature labor.
research Decreased allopregnanolone induced by hormonal contraceptives is associated with a reduction in social behavior and sexual motivation in female rats
Hormonal contraceptives may reduce social behavior and sexual motivation by lowering allopregnanolone levels.
research Therapeutic potential of isoproterenol in androgenetic alopecia: activation of hair follicle stem cells via the PI3K/AKT/β-Catenin signaling pathway
Isoproterenol may help treat hair loss by activating hair follicle stem cells.
research Progesterone and allopregnanolone enhance the miniature synaptic release of glycine in the rat hypoglossal nucleus
Progesterone and allopregnanolone increase glycine release in rat brain cells.
research Involvement of neurosteroids in the control of prolactin secretion in sheep under basal, stressful and pregnancy conditions
Neurosteroids affect prolactin levels in sheep differently depending on stress and pregnancy conditions.
research Molecular Interactions of New Pregnenedione Derivatives
The new progesterone derivatives effectively inhibit 5α-reductase and bind to the androgen receptor.
research Crystal Structure and Synthesis of 17α-Hexanoyloxy-16β-methylpregna-4,6-diene-3,20-dione
A new compound that could treat various androgen-related conditions was created and analyzed.
research Biological activity of novel progesterone derivatives having a bulky ester side chains at C-3
The more lipophilic the progesterone derivative, the better it binds to androgen receptors and has antiandrogenic effects.
research Anxiolytic activity of progesterone in progesterone receptor knockout mice
Progesterone reduces anxiety without needing progesterone receptors.
research Synthesis and Pharmacological Evaluation of New Progesterone Esters as 5.ALPHA.-Reductase Inhibitors
Smaller substituents at C-17 enhance the inhibitory activity of progesterone derivatives on 5alpha-reductase.
research The role of pregnane neurosteroids in ethanol withdrawal: behavioral genetic approaches
Adjusting neurosteroid levels may help reduce alcohol withdrawal symptoms.
research Role of allopregnanolone biosynthesis in acute stress-induced anxiety-like behaviors in mice
Blocking allopregnanolone production in mice makes them more anxious after stress, but this can be reversed with a drug that mimics allopregnanolone.
research Neuroactive Steroid Levels are Modified in Cerebrospinal Fluid and Plasma of Post‐Finasteride Patients Showing Persistent Sexual Side Effects and Anxious/Depressive Symptomatology
Finasteride use changes brain chemicals, causing lasting sexual issues and anxiety/depression.
research Neuroactive steroid levels and psychiatric and andrological features in post-finasteride patients
Post-finasteride patients show changed neuroactive steroid levels, possibly causing erectile dysfunction and depression.
research Effects of Subchronic Finasteride Treatment and Withdrawal on Neuroactive Steroid Levels and Their Receptors in the Male Rat Brain
Finasteride treatment changes brain steroid levels and receptors, affecting brain function even after stopping treatment.
research Physiopathological role of the enzymatic complex 5α-reductase and 3α/β-hydroxysteroid oxidoreductase in the generation of progesterone and testosterone neuroactive metabolites
The enzymes 5α-reductase and 3α/β-hydroxysteroid oxidoreductase help create brain-active substances from progesterone and testosterone, which could be used for treatment, but more research is needed to ensure their safety and effectiveness.
research The influence of low dose finasteride, a type II 5α-reductase inhibitor, on circulating neuroactive steroids

11α-Hydroxyprogesterone is changed into different substances by certain enzymes and may play a role in prostate cancer.
research Investigation of the mechanisms of progesterone protection following oxygen–glucose deprivation in organotypic hippocampal slice cultures
Progesterone protects brain cells by converting to allopregnanolone and involving GABAA receptors.
