Histamine is the agonist for histamine receptor and a vasodilator. Histamine is an organic nitrogen compound that participates in local immune responses, regulates intestinal physiological functions, and acts as a neurotransmitter. Histamine affects p38 MAPK/Akt signaling pathway, exhibits antitumor, antioxidant and anti-inflammatory activities. Histamine can be used in the research of acute myeloid leukemia, malignant melanoma, and renal cell carcinoma.

In Vitro

Histamine (0.01-10 μM, 72 h) exhibits a bidirectional regulatory effect on the proliferation of MDA-MB-231, arrests the cell cycle at G2/M phase, induces the formation of lipid droplet, induces differentiation and apoptosis in MDA-MB-231^[4].
Histamine (10 μM, 24 h) increases the generation of ROS, especially H₂O₂, reduces the activity of antioxidant enzymes (such as catalase), thereby promoting radiosensitivity in MDA-MB-231^[4].
Histamine (1-100 μM, 12 h) inhibits the migration of microglia and the release of inflammatory mediator IL-1β in LPS (HY-D1056)-stimulated N9 mouse microglial, exhibits anti-inflammatory activity^[5].

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

Cell Proliferation Assay^[4]

Cell Line:	MDA-MB-231
Concentration:	0.01-10 µM
Incubation Time:	72 h
Result:	Promoted cell proliferation at 10 µM, inhibited cell proliferation at 0.01 µM.

Apoptosis Analysis^[4]

Cell Line:	MDA-MB-231
Concentration:	10 µM
Incubation Time:	48 h
Result:	Induced apoptosis.

In Vivo

Note:
Please do not refer to only one article to determine the experimental conditions. It is recommended to determine the optimal experimental conditions (animal strain, age, dosage, frequency and cycle, detection time and indicators, etc.) through preliminary experiments before the formal experiment.

Histamine (0.05-100 μg/mouse, icv, single dose) exhibits analgesic effect at high doses of histamine (50-100 μg/mouse), causes hyperalgesia at low doses (0.1-1 μg/mouse) in mouse model^[3].
Histamine dihydrochloride (62.5-2000 μg; Intravaginal injection) can exert a similar effect to estrogen in ovariectomized mice, causing a decrease in intravaginal tetrazolium, an increase in epithelial growth, and keratinization^[6].
Histamine can be used in animal modeling to create gastrointestinal ulcer models^[1].

Induction of Gastrointestinal Ulcer^[1]

Background

Histamine can cause increased gastric acid secretion, decreased mucus production, reflux of pancreatic juice, poor gastric blood flow, and thus gastric ulcers. Stress can cause increased gastrointestinal motility, making the gastric folds more susceptible to damage when exposed to acid.

Specific Modeling Methods

Guinea Pig: male • albino • Administration: 5 mg/kg • i.p. • single dose

Note

(1) No eating or drinking is allowed 24 hours before the experiment.
(2) The animals are sacrificed 2 hours after histamine injection, and treated with 1% formalin to check for gastric ulcers.

Modeling Indicators

The ulcers were punctate or elongated. After the model was dissected, the ulcer index (the sum of the lengths of the lesions) was measured under a microscope to be 3.4 mm.

Opposite Product(s): Cimetidine (HY-14289)

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

Animal Model:	Mouse model^[3]
Dosage:	0.05-100 μg/mouse
Administration:	icv, single dose
Result:	Prolonged the licking latency at the dose of 50 and 100 μg/mouse. Shortened the licking latency at the dose of 0.1-1 μg/mouse.

Animal Model:	Ovariectomized female mice of the SW strain^[6]
Dosage:	62.5-2000 μg
Administration:	Intravaginal injection
Result:	Stimulated a vaginal response similar to that caused by estrogen, resulting in a decrease in intravaginal tetrazolium, increased epithelial growth, and keratinization.

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.
