BPC 157: The Healing Miracle Molecule

What is BPC 157?

The human body has a remarkable system of self-healing and damage repair. One of the important components of this system is a protein called Body Protection Compound (BPC) 157.

BPC 157 is a peptide made up of 15 amino acids; and is produced by the body in the acidic environment of the stomach. The peptide is well-known for its ability to heal, repair and regenerate. Studies suggest that BPC 157 is useful in the treatment of ulcers in the digestive tract as well as management of inflammatory bowel disease (IBD), a group of inflammatory disorders of the digestive tract. BPC 157 also facilitates wound healing of various tissues, including skin, muscle, bone, ligament, and tendon.

BPC 157 in the Digestive Tract

Given that BPC 157 is present in the juices of the stomach, we would expect it to be involved in functioning of the digestive tract. And this is indeed the case. In fact, BPC 157 is also called “stable gastric pentadecapeptide”as it remains stable in human gastric juices for at least 24 hours.

BPC 157 has several functions in the digestive tract. It preserves the integrity of the stomach lining, improves digestion, and facilitates healing throughout the digestive tract. It is particularly helpful in [1] [2]:

  1. Inflammatory bowel disease; such as Ulcerative Colitis, Crohn’s Disease and Esophagitis
  2. Fistula and intestinal anastomosis (the latter is a process where a section of an intestine is cut and removed. The two ends are then surgically connected.)
  3. Reversing short bowel syndrome
  4. Protecting the gastro-intestinal tract from NSAID overuse

Much of the healing capacity of BPC 157 comes from its ability to:

  • Protect the endothelium – inner lining of blood vessels and the lymphatic system known as the endothelium,
  • Play an important role in the formation of new blood vessels – a process known as angiogenesis.

BPC 157 as an Anti-ulcer Agent

BPC 157 is a cytoprotective agent; meaning it can limit the damage to gastric mucosa by agents that trigger ulcer formations. Most importantly, it doesn’t prevent gastric acid secretion but strengthens the protection for gastric mucosa.

NSAID’s or non-steroidal anti-inflammatory drugs are commonly used to relieve pain and inflammation. Overuse of NSAIDs is known to cause ulcers and even bleeding in the digestive tract. BPC 157 possesses the ability to heal these ulcers and a study published in 2013 noted that BPC 157 has clear antidote activity against NSAIDS side effects; and that the “variety of the beneficial effects portrayed by BPC 157 may well be a foundation for establishing BPC 157 as a NSAIDs antidote since no other single agent has portrayed a similar array of effects.” [3]

In addition, BPC 157 can heal lesions in the liver developed due to overuse of alcohol. These lesions can lead to liver tissue damage. Thus, BPC 157 can protect the liver from further deteriorating.

BPC 157 in Inflammatory Bowel Disease

BPC 157 shows great potential in reducing the symptoms of advanced inflammatory bowel disease (IBD). The peptide combines its anti-inflammatory and healing properties to manage the following conditions:

  • Crohn’s disease: chronic inflammation affecting the digestive tract. It causes abdominal pain, diarrhea, and poor absorption of nutrients leading to fatigue and malnutrition.
  • Ulcerative colitis: formation of ulcers and open sores in the colon
  • Esophagitis: inflammation of the esophagus (food pipe) making it extremely painful and difficult swallow.

BPC 157 in Wound Healing

Wound healing is a complex process involving a sequential, cascade of events; which are critical for maintaining the integrity of the body.

BPC 157 holds tremendous potential in wound healing of many tissues such as skin, muscle, bone, ligaments, and tendons. It reduces inflammation at the wound site and allows faster healing of bone ligaments, damaged muscle, Achilles tendons and skin wounds [4] [5].

There are three major processes by which BPC 157 plays a vital role in wound healing; angiogenesis, granulation tissue formation, and production of collagen. All of these mechanisms are central to any healing process occurring within the body.

Angiogenesis is a process where new blood vessels are formed around the site of injury. It allows new blood vessels to send oxygen, nutrients, and inflammatory cells to the healing and regenerating tissues. BPC 157 increases the expression of vascular endothelial growth factor (VEGF) that promotes angiogenesis [6].

A quick primer on VEGF

VEGF is a protein that signals the growth of new blood vessels when a tissue is damaged. It is a very important process that serves to reinstate the blood supply; and with it oxygen and nutrition, to the tissues at the time of reduced blood circulation. In other words, during an injury, the growth factor triggers the sprouting of new blood vessels – an action that increases the influx of nutrients to the damaged tissue.

BPC 157 exerts a particularly effective role in tendon healing. Muscles have a remarkable process of healing; owing to a highly-evolved system of blood vessels and also stem cells. However, tendons lack this blood vessel network and as a result there is a reduced flow of oxygen and nutrients to the recuperating tendon. This leads to impaired healing.

BPC 157, by up-regulating VEGF, triggers an adequate and controlled angiogenic response that allows tendons to heal faster. Controlled angiogenesis is important, as prolonged instances interferes in healing, eventually leading to chronic tendon disease.

BPC 157 achieves effective muscle and tendon healing by regulating certain underlying complex processes, “In tendon and muscle healing its functional, biomechanical, and pathohistological beneficial effect is accompanied by angiogenic action. BPC 157 may directly protect endothelium, influence the NO-system, counteract the effect of both NOS-inhibitor and NO-precursor as well as over expression of endothelin.”

The anti-inflammatory properties of BPC 157 further contribute to its healing benefits. The peptide decreases the concentration of inflammatory mediators in the injured or damaged tissues – promoting the wound healing process and allowing the tissue to heal faster.

BPC Influences the NO system

BPC 157 interacts with, and modulates the nitric oxide (NO) system; an important property responsible for many of its wound healing and tissue repair outcomes.

NO is a gas naturally produced by the body and is implicated in many aspects of repair, healing and regeneration processes – involving angiogenesis, inflammation, cell proliferation, matrix deposition, and remodeling to name a few. Nitric oxide plays a particularly important role in mediating a number of inflammatory responses and promoting angiogenesis (growth of new blood vessels).

Furthermore, a study showed that the protein’s ability to influence the NO system may be helpful in many conditions [7]:

  1. Protects the gastric mucosa following alcoholic lesions
  2. Alcohol intoxication and withdrawal
  3. Cardiovascular problems, including chronic heart failure, irregular heart beat and elevated blood pressure in the arteries of the lungs
  4. Changes in blood potassium levels that can lead to dysfunction of the cell membranes
  5. Complications with fistula healing; both of colon and esophagus.

BPC 157 is safe with no side effects

BPC 157 is naturally produced by the body in small amounts. There are no reported side effects associated with its use. With no Lethal Dose 1 achieved for BPC 157, it enjoys quite a high safety profile. Lethal Dose 1 of any substance is the dose at which 1 % of the test population is killed.

Beneficial effect of a novel pentadecapeptide BPC 157 on gastric lesions induced by restraint stress, ethanol, indomethacin, and capsaicin neurotoxicity

 

Abstract
Very recently, the integrity of capsaicin somato sensory neurons and their protection were suggested to be related to the activity in nociception of a newly discovered 15-amino acid peptide, BPC 157, shown to have strong beneficial effect on intestinal and liver lesions.

Therefore, from this viewpoint, we have studied the gastroprotective effect of the pentadecapeptide BPC 157, on gastric lesions produced in rats by 96% ethanol, restraint stress, and indomethacin.

The possible involvement of sensory neurons in the salutary actions of BPC 157 (10µg/kg, 10 ng/kg intraperitoneally) was studied with capsaicin, which has differential effects on sensory neurons: a high dose in adult (125 mg/kg subcutaneously, 3 months old) or administration (50 mg/kg subcutaneously) to neonatal animals (age of the 7 days) destroys sensory fibers, whereas a low dose (500µg/kg intraperitoneally) activates neurotransmitter release and protective effects on the mucosa.

In the absence of capsaicin, BPC 157 protected gastric mucosa against ethanol, restraint, and indomethacin application. In the presence of neurotoxic doses of capsaicin, the negative influence of capsaicin on restraint, ethanol, or indomethacin lesions consistently affected salutary activity of BPC 157.

However, BPC 157 protection was still evident in the capsaicin-treated rats (either treated as adults or as newborns) in all of these assays. Interestingly, after neonatal capsaicin treatment, a complete abolition of BPC gastroprotection was noted if BPC 157 was applied as a single nanogram-regimen, but the mucosal protection was fully reversed when the same dose was used daily. In line with the excitatory dose of capsaicin the beneficial effectiveness of BPC 157 appears to be increased as well.

Taken together, these data provide evidence for complex synergistic interaction between the beneficial effectiveness of BPC 157 and peptidergic sensory afferent neuron activity.

Abstract

The reported beneficial effects of the gastric mucosal derived pentadecapeptide BPC 157 (Gly Glu Pro Pro Pro Gly Lys Pro Ala Asp Asp Ala Gly Leu Val, M.W. 1419) on different organ lesions are reviewed.

Apart from the effects on various gastrointestinal lesions, the potentially beneficial effect on pancreas, liver injuries, endothelium and heart damage, i.e. dysrhythmias following reoxygenation, and blood pressure, along with effect on experimental acute/chronic inflammation, wound and fracture (pseudoarthrosis) healing are described.

It appears that these beneficial effects all together provide a particular network reflecting activity of a special peptidergic defence system. In support of this concept, it appears that there are interactions of this pentadecapeptide with many important systems (namely, dopamine-, NO-, prostaglandin-, somatosensory neurone-systems), that could provide a basis for the observed protective effects. Moreover, since disturbance of these systems’ functions (i.e. dopamine-, NO-, somatosensory neuronal-system) which manifest either over-activity or as inhibition, may contribute to the multiple lesions in different organs.

The reported evidence that this pentadecapeptide is able to counteract both their over-action, and their inhibition, may suggest this pentadecapeptide as a new, but most probably essential physiological defence system and that should be further investigated.

BPC 157. ATTENUATED GASTRIC ULCERS, SEIZURES, BRAIN LESIONS, HEPATOMEGALY, FATTY LIVER

This trial shows the effectiveness of BPC157 on damages caused by insulin over dosage, which can be very useful for diabetics who inject themselves too much insulin… extracts:

OVER-DOSE INSULIN AND STABLE GASTRIC PENTADECAPEPTIDE BPC 157. ATTENUATED GASTRIC ULCERS, SEIZURES, BRAIN LESIONS,  HEPATOMEGALY, FATTY LIVER, BREAKDOWN OF LIVER GLYCOGEN, PROFOUND HYPOGLYCEMIA AND CALCIFICATION IN RATS

INTRODUCTION

The general significance of insulin induced ulcers remains not determined. We focused on hyperinsulinemia, deliberate injection of excessive insulin, and possibility that an anti-ulcer therapy with anti-ulcer peptide may be more successful counteracting therapy.

Insulin induced ulcers were long ago described, and related to gastric acid hypersecretion (1, 2).

Thus, to provide some novel intriguing insights, we focused on insulin induced gastric ulcers (1, 2) and then on other disturbances that may be concomitantly induced by insulin application (3-5).

 

We focused on a peptide therapy, using a small, orally active, anti-ulcer peptide (7-11) stable gastric pentadecapeptide BPC 157 (MW 1419) with very safe profile (LD1 could be not achieved, no side effects in clinical trials (12, 13) stable in human gastric juice (14), effective in trials for inflammatory bowel disease therapy (12, 13) and wound healing (15-18) also in diabetic rats (18, 19).

Importantly, pentadecapeptide BPC 157 was more active than recombinant human platelet-derived growth factor (PDGF-BB), stimulating both expression of early growth response 1 (egr-1) gene and its repressor nerve growth factor 1- A binding protein-2 (NAB2) (18).

Thereby, it may be important for cytokine induction, growth factor generation, early extracellular matrix (collagen) formation (18), but also for gluconeogenesis regulation (20).

Finally, alloxan-gastric ulcers in rats and mice may be inhibited by stable gastric pentadecapeptide BPC 157 (21).

 

DISCUSSION

Thus, when given to insulin-rats, BPC 157 would be confronted with the all processes simultaneously occurring that eventually lead to stomach ulcer (1, 2), hypoglycemia and all mentioned disturbances and death in insulin over-dose-rats (3-5). However, we shown that pentadecapeptide BPC 157, as an antiulcer peptide (7-11), may besides stomach ulcer consistently counteract all insulin disturbances and fatal outcome. This may also indicate that these disturbances are also interconnected throughout BPC 157 background. Moreover, considering the used insulin (250 IU/kg i.p.) /BPC 157 (10 µg, 10 ng/kg i.p. or i.g.) ratio (7, 8), it may be reasonably to assume that these therapy effects may indicate a likely role of BPC 157 in insulin controlling and influence on one or more causative process(es).

 

In conclusion, these findings demonstrate that when one application of very high dose of insulin may induce together stomach ulcer, seizures, severely damaged neurons in cerebral cortex and hippocampus, hepatomegaly, fatty liver, breakdown of liver glycogen with profound hypoglycemia, along with calcium deposition, and finally fatal outcome in rats, all damages were markedly attenuated when BPC 157 was applied.

The same effectiveness when given intraperitoneally or intragastrically (i.e., stable in human gastric juice (14)) may be suggestive that BPC 157 may have also an incretin role in controlling insulin effects (7, 8, 11).

Intriguingly, further studies may show whether standard anti-ulcer agents that prevent insulin-stomach ulcer (1, 2) may also have a broader beneficial effect on other disturbances presented in insulin-rats.

Previously, BPC 157 was shown to counteract toxic effects of other insulin preparations (43).
