Amylin, rat CAS NO.124447-81-0

Amylin, rat (CAS NO. 124447-81-0) is a synthetic 37-amino acid peptide representing the rat isoform of Islet Amyloid Polypeptide (IAPP). This research-grade hormone is co-secreted with insulin from pancreatic β-cells. The rat amylin sequence differs significantly from the human sequence at key positions, making it non-amyloidogenic. It is an essential tool for studying the <stron…

1.MECHANISM OF ACTION

Rat amylin exerts its physiological effects by binding to and activating specific amylin receptors, which are complexes of the Calcitonin Receptor (CTR) and Receptor Activity-Modifying Proteins (RAMPs). Its primary mechanisms in rodent models are:

Inhibition of Glucagon Secretion: Acts on the pancreas to suppress postprandial glucagon release from α-cells, reducing hepatic glucose output.
Delay of Gastric Emptying: Signals via receptors in the hindbrain (area postrema) to slow the rate at which food empties from the stomach into the small intestine, moderating the post-meal rise in blood glucose.
Induction of Satiety: Acts centrally in the brain to promote feelings of fullness, leading to reduced food intake. This anorexigenic effect is a key area of study in obesity research.
Critical Distinction – Non-Amyloidogenic: Unlike human or feline amylin, rat amylin contains proline substitutions that prevent β-sheet formation and toxic aggregation. This makes it ideal for studying amylin's native hormonal signaling without the complication of islet amyloid pathology.

2.PRODUCT INDICATIONS

This product is specifically indicated for preclinical research using rat models in metabolism, endocrinology, and neuroscience. Key applications include:

Physiology of Glucose Homeostasis: Studying the normal, protective role of amylin in postprandial glucose regulation in healthy and diabetic rodent models.
Obesity & Feeding Behavior Research: Investigating the anorexigenic (satiety) effects of amylin and its potential as a target for weight loss therapies.
Pharmacology of Amylin & Analogs: Serving as the species-specific reference agonist for testing the effects of endogenous amylin or novel amylin mimetics (like pramlintide) in rat-based experiments.
Comparative Biology: Contrasting the effects of non-amyloidogenic (rat) vs. amyloidogenic (human) amylin sequences in cellular and animal models to understand the structural basis of toxicity.
Gastrointestinal Motility Studies: Research on hormonal control of gastric emptying.

3.CLINICAL EFFICACY OF PRODUCT

Rat amylin itself is not a human therapeutic. However, research using rat amylin has been fundamentally critical for establishing the physiological actions of the amylin hormone system, which directly enabled clinical drug development.

Foundational Science: Studies in rats (and mice) using rat amylin or its analogs were instrumental in proving that amylin:
- Reduces food intake and promotes weight loss.
- Lowers blood glucose via glucagon suppression and gastric emptying delay.
Enabling Drug Development: This robust physiological data from rodent models validated the amylin pathway as a therapeutic target for diabetes and obesity. It provided the essential proof-of-concept that led to the development of pramlintide, the stable, non-aggregating human amylin analog approved for diabetes treatment.
Safety Profile Evidence: The non-toxic nature of rat amylin in rodent islets helped differentiate the hormone's beneficial signaling effects from the detrimental amyloid effects of human IAPP.
