体内実験

Induction of chronic progressive pulmonary hypertension (PH)

Background
Pulmonary arterial hypertension (PAH) is characterized by vascular remodeling of the distal pulmonary arterial circulation. PAH remodeling includes apoptosis and proliferation of pulmonary vascular endothelial cells, muscularization of distal pulmonary arterioles, deposition of extracellular matrix proteins, and perivascular inflammation; it is accompanied by increased pulmonary vascular resistance, leading to right ventricular (RV) failure and death. However, the cause of pulmonary vascular remodeling in PAH is still unclear. Monocrotaline induces right ventricular hypertrophy (RVH) and pulmonary vascular remodeling.
Specific Mmodeling Methods
Rat[10]: male • adult Sprague Dawley rats • 300-350 g
Administration: 60 mg/kg • sc for single dose • control group: saline solution
Mcie[11]: male • C57BL/6 mice • 6-8 weeks old
Administration: 600 mg/kg • sc • once weekly for 4 weeks
Note
1. Monocrotaline-induced pulmonary hypertension can be reversed by tail vein injection of 25 μg mouse mesenchymal stem cells in 100 μL PBS three hours after each injection. 2. Extracellular vesicles (EVs) isolated from the circulation or lungs of mice with monocrotaline-induced pulmonary hypertension induce right ventricular hypertrophy (RVH) and pulmonary vascular remodeling when injected into healthy mice.
Modeling Record
Molecular changes: ↑ expression of 5-HTR2A, 5-HTR2B and 5-HTT in lung homogenate; ↑ expression of IL-1b, IL6, TNF-a and MCP-1; ↑ levels of total collagen fibers and total pulmonary vascular collagen.
Physiological indicators: Increased right ventricular systolic pressure, right heart hypertrophy, gas exchange; collagen deposition in the pulmonary artery.

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:  5% DMSO    40% PEG300    5% Tween-80    50% Saline

    Solubility: ≥ 2.5 mg/mL (7.68 mM); Clear solution

  • Protocol 2

    Add each solvent one by one:  5% DMSO    95% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (7.68 mM); Suspended solution

For the following dissolution methods, please prepare the working solution directly. It is recommended to prepare fresh solutions and use them promptly within a short period of time.
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:  PBS

    Solubility: 4.17 mg/mL (12.82 mM); Clear solution; Need ultrasonic and warming and heat to 60°C

  • Protocol 2

    Add each solvent one by one:  20% HP-β-CD in Saline

    Solubility: 21 mg/mL (64.54 mM); Clear solution; Need ultrasonic and warming and heat to 53°C

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
