Product Introduction

Bioactivity

Description	Progesterone is a steroid hormone that regulates the menstrual cycle and is essential for pregnancy. It is also commonly used to induce melasma models.
In vitro	Progesterone drives a series of events in which luminal cells may furnish basal cells with Wnt4 and RANKL signals, which in turn respond by upregulating homologous receptors, transcriptional targets, and markers of the cell cycle. Progesterone exhibits a biphasic effect on the proliferation of breast cancer cells; it stimulates growth during the initial cell cycle and subsequently impedes cell progression at the G1/S phase.
In vivo	Twenty-one days after dorsal medial thalamic nuclei damage, rats treated with progesterone exhibited reduced neuronal degeneration. In female 3xTg-AD mice, progesterone negated the advantageous effects against Abeta accumulation, yet it did not affect behavioral performance. During the Morris water maze spatial navigation task, progesterone-treated rats demonstrated less impairment compared to control rats.
Synonyms	Pregn-4-ene-3,20-dione
Disease Modeling Protocol	Pulmonary fibrosis model Modeling Mechanism： Progesterone exacerbates pulmonary fibrosis through multiple mechanisms: ① It promotes myofibroblast activation (increased α-SMA expression) and increases collagen deposition; ② It upregulates the key fibrotic cytokine TGF-β, inhibits matrix metalloproteinase 9 (MMP9) activity, and disrupts the degradation balance of the extracellular matrix (ECM); ③ It inhibits systemic inflammation (reducing serum TNF-α) while increasing cortisol levels, promoting excessive tissue repair through the imbalance of "anti-inflammatory-fibrotic"; ④ It directly induces subpleural fibrosis in normal lung tissue and, under pathological conditions, synergistically exacerbates damage with bleomycin. Related Products： Progesterone (T0478) Modeling Method： Experimental Subject： Mice: BALB/c strain, female, 6–8 weeks old, approximate body weight 20 g Dosage and Administration Route： ① Fibrosis induction: Bleomycin (1.5 U/mL) at 0.075 U/g administered via subcutaneous injection in the back, once daily for 28 days; ② Progesterone intervention: - Synchronised intervention group (BLM+P28): 1 mg/animal (50 μg/g) progesterone, subcutaneous injection, initiated concurrently with bleomycin, for 28 days; - Delayed intervention group (BLM+P21): 1 mg/animal progesterone, subcutaneous injection, initiated one week after bleomycin injection, for 21 days; ③ Control Groups: Pure bleomycin group (BLM), pure progesterone group (P21/P28), PBS control group Dosing Frequency and Duration Model： Bleomycin administered once daily for 28 days Progesterone intervention once daily for 21 or 28 days Validation： Histological markers: Fibrosis degree: Masson trichrome staining showed significantly increased collagen deposition in the lung tissue of the BLM+P28 group (P<0.0001), while subpleural fibrosis was observed in the progesterone-only group (P28) (P<0.001); Molecular markers: Increased expression of α-SMA (P<0.01) and TGF-β (P<0.05) and decreased MMP9 activity (P<0.05) in the lung tissue of the BLM+P28 group, and downregulated expression of Col1a2, Ctgf, and Edn1 genes; Serum markers: Decreased TNF-α level (P<0.05) and increased cortisol level (P<0.05) in the BLM+P group; Specificity verification: Hydroxyproline detection showed increased hydroxyproline content in the lung tissue of the BLM+P28 group (P<0.05), consistent with the collagen deposition results, confirming the aggravation of fibrosis. Precautions： At the end of the study, the lung and injured skin were removed under deep anesthesia. References：Vafashoar F,et,al.

Please enter your animal experiment information in the following box and click Calculate to obtain the stock solution preparation method and in vivo formula preparation method:

For example, if the intended dosage is 10 mg/kg for animals weighing 20 g , with a dosing volume of 100 μL per animal, and a total of 10 animals are to be administered, using a formulation of 10% DMSO+ 40% PEG300+ 5% Tween 80+ 45% Saline/PBS/ddH₂O , the resulting working solution concentration would be 2 mg/mL.

Stock Solution Preparation:

Dissolve 2 mg of the compound in 100 μL DMSO to obtain a stock solution at a concentration of 20 mg/mL . If the required concentration exceeds the compound's known solubility, please contact us for technical support before proceeding.

Preparation of the In Vivo Formulation:

1) Add 100 μL of the DMSO stock solution to 400 µL PEG300 and mix thoroughly until the solution becomes clear.

2) Add 50 µL Tween 80 and mix well until fully clarified.

3) Add 450 µL Saline,PBS or ddH₂O and mix thoroughly until a homogeneous solution is obtained.
