In Vivo

Modeling ON-OFF system for gene expression^[6]^[7]

Background

Doxycycline is often used as an inducer in molecular biology research to induce gene expression. In cells or model animals that have constructed a Tetracycline (Tet; HY-A0107) inducible expression (Tet-ON/Tet-OFF) system, the expression of the target gene can be precisely controlled by adding or removing Doxycycline. Doxycycline can act as an inhibitor of transcriptional activation in the Tetracycline (Tc)-controlled transactivation (tTA) system, and as an inducer of transcriptional activation in the "reverse tTA' system. Doxycycline and Tetracycline both act systemically after being absorbed by the upper gastrointestinal tract. In comparison, the main advantage of Doxycycline is that it has a longer activity and can be taken twice or once a day. Although the peak concentrations of the two are similar, Doxycycline takes a shorter time to reach peak concentration and has a significantly longer half-life ^[6]^[7]^[8].

Specific Mmodeling Methods

Rat^[8]: male • adult middle-aged (12-month-old) • Sprague-Dawley rats
Administartion (for GDNF regulation): 3g/kg (Doxycycline; HY-N05655) (dietary with regular food) • po once daily for 6 days • monitored every day

Note

1. In this study^[7], a recombinant adeno-associated virus (rAAV)-based bicistronic tetracycline (tet)-OFF construct was used for dynamic control of GDNF (target gene) expression during long-term expression.
2. 3g/kg dietary DOX produced DOX serum levels equivalent to 1mg/ml DOX in drinking water.

Modeling Record

(1) The expression level of the target gene decreases; (2) The positively correlated phenotype corresponding to the target gene is alleviated.

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

Animal Model:	6-month-old female Heterozygous Col3a1-deficient (HT) mice^[3]
Dosage:	200 or 800 mg/kg
Administration:	Oral gavage; 200 or 800 mg/kg; once daily; 3 months
Result:	Reduced MMP-9 activity in a dose-dependent manner.

In Vivo:

Select the appropriate dissolution method based on your experimental animal and administration route.

For the following dissolution methods, please ensure to first prepare a clear stock solution using an In Vitro approach and then sequentially add co-solvents:
To ensure reliable experimental results, the clarified stock solution can be appropriately stored based on storage conditions. As for the working solution for in vivo experiments, it is recommended to prepare freshly and use it on the same day.
The percentages shown for the solvents indicate their volumetric ratio in the final prepared solution. If precipitation or phase separation occurs during preparation, heat and/or sonication can be used to aid dissolution.

Protocol 1

Add each solvent one by one: 10% DMSO 40% PEG300 5% Tween-80 45% Saline
Solubility: ≥ 2.5 mg/mL (5.20 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 400 μL PEG300, and mix evenly; then add 50 μL Tween-80 and mix evenly; then add 450 μL Saline to adjust the volume to 1 mL.
Preparation of Saline: Dissolve 0.9 g sodium chloride in ddH₂O and dilute to 100 mL to obtain a clear Saline solution.
Protocol 2

Add each solvent one by one: 10% DMSO 90% (20% SBE-β-CD in Saline)
Solubility: ≥ 2.5 mg/mL (5.20 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown).
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL 20% SBE-β-CD in Saline, and mix evenly.
Preparation of 20% SBE-β-CD in Saline (4°C, storage for one week): 2 g SBE-β-CD powder is dissolved in 10 mL Saline, completely dissolve until clear.
Protocol 3

Add each solvent one by one: 10% DMSO 90% Corn Oil
Solubility: ≥ 2.5 mg/mL (5.20 mM); Clear solution

This protocol yields a clear solution of ≥ 2.5 mg/mL (saturation unknown). If the continuous dosing period exceeds half a month, please choose this protocol carefully.
Taking 1 mL working solution as an example, add 100 μL DMSO stock solution (25.0 mg/mL) to 900 μL Corn oil, and mix evenly.
