Clobetasol

Avis client

Based on 1 Customer Validation

Clobetasol is a glucocorticoid and Smoothened agonist that can cross the blood-brain barrier. Clobetasol induces Smo-dependent activation of the Shh signaling pathway and nuclear translocation of Gli1. Clobetasol promotes remyelination and reduces myelin loss in lesions of neuromyelitis optica (NMO). Clobetasol may cause adrenal suppression, cushingoid appearance, and local adverse reactions including dysgeusia, xerostomia, and gastroesophageal burning. Clobetasol can be used in research related to neurodegenerative diseases, oral lichen planus, mucous membrane pemphigoid, and neuromyelitis optica.

In Vitro

Clobetasol (0.1-25 µM) enhances the metabolic turnover of neural stem cells (NSCs) derived from the subventricular zone (SVZ) of mice via a Smo-dependent signaling pathway^[1].
Clobetasol (5 µM) doubles the cell growth rate of neural stem cells (NSCs) derived from the subventricular zone (SVZ) of mice via the Smo-dependent signaling pathway^[1].
Clobetasol increases Gli1 mRNA levels in mouse SVZ-derived neural stem cells (NSCs) via the Smo-dependent signaling pathway^[1].
Clobetasol (0.3-10 μM; 6 days) promotes the maturation of primary mouse oligodendrocyte precursor cells, and approximately 15% of the cells become MBP-positive after incubation at 5 μM for 6 days^[3].
Clobetasol (6 days) promotes remyelination and increases the number of mature oligodendrocytes in cultured mouse cerebellar slices with demyelination induced by AQP4-IgG and complement after 6 days of treatment^[3].

Cell Viability Assay^[1]

Cell Line:

mouse subventricular zone (SVZ)-derived neural stem cells (NSCs)
Concentration:

0.1 µM, 1 µM, 5 µM, 25 µM; 5 µM plus 1 µM cyclopamine
Incubation Time:

Not specified
Result:

Increased NSC MTT turnover to 152.1% of control levels at 5 µM, with a p-value < 0.0001.
Caused a dose-dependent reduction in MTT turnover at 0.1, 1, 25 µM.
Reversed the increased MTT turnover induced by 5 µM clobetasol when co-treated with 1 µM cyclopamine.

In Vivo

Clobetasol (2 mg/kg/day; intraperitoneal injection; days 5 to 8) reduces myelin loss by approximately 60% and increases the number of mature oligodendrocytes in a mouse model of neuromyelitis optica^[3].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model:

CD1 (male, wild-type, 10-12 weeks of age, intracerebral stereotaxic infusion of AQP4-IgG and human complement)^[3]
Dosage:

2 mg/kg/day
Administration:

i.p.; daily; 8 days (day 1 to day 9); daily; 5 days (day 4 to day 9)
Result:

Reduced myelin loss by ~60% compared to vehicle-treated mice.
Increased the number of mature CC1-positive oligodendrocytes in and around lesions significantly compared to vehicle-treated mice.
Did not significantly alter initial astrocyte damage (AQP4 loss), inflammation (Iba1 and CD45 immunofluorescence), or complement activation (C5b-9 deposition) compared to vehicle.
Produced significantly greater remyelination than vehicle when administered starting on day 4 (post-demyelination).

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
