L'hexareline, également appelée examens, est un analogue synthétique de la ghréline et est étroitement lié au GHRP-6. En fait, l'hexareline et le GHRP-6 diffèrent les uns des autres, ne remerciant que deux groupes méthyle à GHRP-6. L'hexareline, comme de nombreux analogues de la ghréline, est oralement et sublingement active et très sélective. L'hexareline a été fortement recherchée pour ses effets sur la survie des cellules cardiaques après l'ischémie et la privation de nutriments.

1. Protége le cœur

L'hexareline affecte directement le cœur en se liant au récepteur du CD36 et au récepteur du sécrétagogue d'hormone de croissance (GHSR). Les études sur les souris suggèrent que l'hexareline protège les cellules cardiaques contre les blessures dans le cadre d'une crise cardiaque en se liant à ces récepteurs et en empêchant les cellules de subir l'apoptose (mort cellulaire programmée). Les souris traitées avec de l'hexareline dans cette étude ont montré une amélioration de la fonction cardiaque, une augmentation du nombre de cellules cardiaques survivantes et une diminution de la production de malondialdéhyde (un marqueur de la mort des cellules cardiaques). Fait intéressant, le GHRP-6 s'est avéré être légèrement supérieur à la ghréline dans cette étude^{[1], [2]}.

A study in rats investigating the ability of GHRP-6 to offset problems associated with heart failure found that the peptide reduces oxidative stress in heart failure and prevents myocardial remodeling from taking place. Remodeling is a pathological process associated with a decline in heart function and serious morbidity. Rats treated with GHRP-6 in this study had significant improvements in the function of their heart. These processes are thought to be mediated by GHRP-6 up-regulation of phosphatase and tensin homologue (PTEN) activity as well as down regulation of protein kinase B expression^[3]. PTEN plays a role in cell regeneration while protein kinase B regulates cell survival.

GHRP-6 is so effective in reducing cardiac remodeling that it shifts the balance of nervous system activity away from sympathetic stimulation (higher heart rate, higher blood pressure, etc.) toward parasympathetic dominance. This not only improves short-term health and outcomes, but reduces the need for medication over the long term and likely helps to prevent cardiac remodeling that is secondary to increased stress on the heart. Rats treated with GHRP-6 following a heart attack show substantial reductions in the size of the scar left behind^{[4], [5]}.

Because the mechanism by which hexarelin protects heart cells is not specific to the mechanism of damage in heart attack, researchers speculated that the peptide could be used to protect the heart from other insults as well. Research, again in rats, found that hexarelin improved cardiac function in a model of diabetes by changing the way calcium and potassium are processed by heart muscle cells^[6]–[8].

2. Improves Fat Measures

Dyslipidemia refers to an abnormal amount of fat in the blood. Interestingly, dyslipidemia is an independent risk factor for the development of diabetes, even in thin and outwardly healthy individuals. In fact, dyslipidemia may help to explain the current diabetes crisis in first-world nations and understanding its effects on human physiology is paramount to combating the growing health concerns associated with modern diets. Research in rats indicates that GHRP-6 can correct dyslipidemia in the setting of insulin resistance (the first step in the pathway to diabetes) while simultaneously lowering blood sugar and insulin resistance^[9]. The peptide may offer an alternative to current lipid medications for the treatment of severe dyslipidemia.

3. Protects Muscle

It isn’t just heart muscle that hexarelin protects. Studies in rat models of cachexia (extreme weight loss due to illness or chemotherapy) indicate that GHRP-6 protects muscle cells by regulating calcium flow as well as mitochondrial dysfunction^[10]. Mitochondria are the power plants of cells. Without them, cells cannot produce the energy they need to carry out normal function and will eventually die.

Calcium regulation is often disrupted by chemotherapy. Calcium dysregulation is one of the primary reasons that muscle mass and lean body mass are affected during cancer treatment. Research in rats indicates GHRP-6 offsets the alterations in calcium regulation caused by chemotherapy^[11].

Heart disease is the leading cause of death in most developed nations. Understanding the complex process that leads to heart disease, heart failure, and eventually death is not easy, but scientists are beginning to unravel the mystery with help from peptides like hexarelin. Research utilizing hexarelin has revealed a number of new pathways for understanding the function of the heart in health and disease. It has also opened the door to develop new treatments for problems, like cardiac remodeling, that have proved difficult to treat in the past.
