Protocol

Cell experiment [1]:

Cell lines

HCT-116 colon cancer cells (expressing GFP-UBXN2A)

Preparation method

The solubility of this compound in DMSO is >10mM. General tips for obtaining a higher concentration: Please warm the tube at 37℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below -20℃ for several months.

Reacting condition

20 and 40 μM, 24 hours

Applications

Veratridine is the main UBXN2A enhancer, increased UBXN2A protein levels in a dose-dependent manner.

Animal experiment [2]:

Animal models

C57Bl/6N mice( HCT-116 cells expressing GFP-UBXN2A were injected into 6 to 8 week old nude female mice)

Dosage form

Intraperitoneal injection (IP), 0.125 mg/kg for 28 days

Application

Veratridine (VTD) was sufficient to induce UBXN2A protein levels, resulting in colon cancer cell death in UBXN2A- and mot-2-dependent manners.

Other notes

Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal.

Background

Voltage-gated Na+ channel opener; increases intracellular Ca2+ with no effect on the Na+/Ca2+ exchanger. Steroid-derived alkaloid neurotoxin. Increases membrane Na+ permeability and depolarizes excitable tissues.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
