The TRPP2-dependent channel of renal primary cilia also requires TRPM3.

open access: yesPLoS ONE, 2019
Primary cilia of renal epithelial cells express several members of the transient receptor potential (TRP) class of cation-conducting channel, including TRPC1, TRPM3, TRPM4, TRPP2, and TRPV4.

Online In-Tube Solid-Phase Microextraction Coupled with Liquid Chromatography–Tandem Mass Spectrometry for Automated Analysis of Four Sulfated Steroid Metabolites in Saliva Samples

open access: yesMolecules, 2022
Accurate measurement of sulfated steroid metabolite concentrations can not only enable the elucidation of the mechanisms regulating steroid metabolism, but also lead to the diagnosis of various related diseases.

Higher steroid sulfation is linked to successful weight loss in obese children

open access: yesEndocrine Connections, 2018
Objective: Little information is available on the steroid sulfates profile in obese children. Therefore, we examined whether sulfated steroids are linked with weight status and associated comorbidities in obese children.

Loss of Transient Receptor Potential Melastatin 3 ion channel function in natural killer cells from Chronic Fatigue Syndrome/Myalgic Encephalomyelitis patients

open access: yesMolecular Medicine, 2018
Background Chronic Fatigue Syndrome (CFS)/ Myalgic Encephalomyelitis (ME) is a debilitating disorder that is accompanied by reduced cytotoxic activity in natural killer (NK) cells. NK cells are an essential innate immune cell, responsible for recognising

Pregnenolone sulfate analogues differentially modulate GABAA receptor closed/desensitised states [PDF]

open access: yes, 2023
BACKGROUND AND PURPOSE: GABAA receptors are regulated by numerous classes of allosteric modulators. However, regulation of receptor macroscopic desensitisation remains largely unexplored and may offer new therapeutic opportunities.

GABAergic neuroactive steroids: a new frontier in bipolar disorders?

open access: yesBehavioral and Brain Functions, 2012
Neurosteroids are synthesized in the brain and modulate brain excitability. There is increasing evidence of their sedative, anesthetic and antiseizure properties, as well as their influence on mood.

Activation of ciliary channels by pregnenolone sulfate.

open access: yes, 2019
(A) The top recording shows the activity of a single ciliary channel observed while recording in the standard solutions (with 0.1 μM cytoplasmic free Ca2+). The bottom recording shows increased channel activity in the same cilium 5 min after perfusion of

Neuroactive steroids in depression and anxiety disorders: Clinical studies [PDF]

open access: yes, 2006
Certain neuroactive steroids modulate ligand-gated ion channels via non-genomic mechanisms. Especially 3 alpha-reduced pregnane steroids are potent positive allosteric modulators of the gamma-aminobutyric acid type A (GABA(A)) receptor.

Metabolism of pregnenolone-4-14C and pregnenolone-7[alpha]-3H sulfate by the Macaca mulatta fetal adrenal in vitro [PDF]

open access: yes, 1971
These studies were initiated to ascertain the feasibility of utilizing the fetal monkey adrenal as a model for further studies on comparative steroid metabolism at various periods of gestation.
