HDAC inhibitors help brain cells grow and improve brain function.
research 11β-Hydroxylase inhibitors protect against seizures in mice by increasing endogenous neurosteroid synthesis
11β-Hydroxylase inhibitors help prevent seizures in mice by boosting natural neurosteroid production.
research Involvement of neurosteroids in the anxiolytic-like effects of AC-5216 in mice
AC-5216 reduces anxiety in mice through neurosteroids affecting GABAA receptors.
research Bound on the Risk for M-SVMs
The enzyme system in hair follicles is similar to the liver's and is inhibited by certain substances.
research Retinoid-mediated stimulation of steroid sulfatase activity in myeloid leukemic cell lines requires RARα and RXR and involves the phosphoinositide 3-kinase and ERK-MAP kinase pathways
Retinoids increase steroid sulfatase activity in leukemia cells through RARα/RXR and involves certain pathways like phosphoinositide 3-kinase and ERK-MAP kinase.
research Molecular interactions of natural and synthetic steroids in female hamsters’ flank organs
Testosterone, progesterone, and levonorgestrel change enzyme levels related to fat production in hamster skin, which could affect skin oil and acne.
research Implications of neuroimaging for the treatment of epilepsy
Neuroimaging suggests that treatments targeting brain steroids could help control epilepsy, especially types linked to the menstrual cycle.
