Follistatin (FST) 344 is a synthetic version of the naturally occurring human follistatin protein. Follistatin is found in nearly all tissues of higher animals and comes in two separate isoforms as a result of alternative gene splicing. Its primary biological function is neutralization of proteins in the TGF-beta superfamily. It has particularly potent neutralizing effects on activin, myostatin, and follicle-stimulating hormone

Follistatin 344 Effects

Follistatin Research and Muscle Growth

Myostatin can be explained as a type of protein and it is produced by cells that prohibit the growth and differentiation of muscle cells. It is also recognized as a member of the TGF-beta protein family and hence is susceptible to prohibition by follistatin. There is some evidence too on the basis of previous research that myostatin genes can cause muscle waste in various diseases, like muscular dystrophy. Animal test subjects with a lack of myostatin usually have more muscle mass and are stronger than normal. Scientists think that activating follistatin proteins through genetic manipulation could be a way to treat diseases like muscular dystrophy.

In mouse models, follistatin has been depicted to addition of lean muscle mass without any requirement for special diet regime or physical exercise. In only eight weeks of follistatin injections, mice used in the treatment group had nearly 10% more muscle mass than mice in the control group[1]. With that said, again, this is a result that has been obtained in the absence of any special diets. Hence, it indicates that muscle gain could be even more significant with appropriate training.

Chronic muscle disorders have been notoriously hard to treat with pharmacologic interventions. The follistatin therapy has been shown to be a promising therapy for chronic muscle disorders, such as muscular dystrophy. Animal models in mice have shown that follistatin initiates hypertrophy of muscle tissue and reduces inflammation and fibrosis when administered at a high dose. Giving the protein on a regular basis has also shown to improve strength in mouse models of Duchenne muscular dystrophy (DMD). These findings are significant and could help doctors give their patients more quality of life by reducing or eliminating the weakness associated with certain chronic muscle disorders. [2] [3]

One interesting aspect of research into the effects of follistatin on muscle growth is that it can lead to long-term benefits on muscle hypertrophy. In mouse models, one-time administration of follistatin via gene therapy has led to more than two years of enhanced mass and strength in both normal and dystrophic animals. These benefits were observed regardless of the age at which the animal was administered the gene; follistatin is effective at any age[4].

Research suggests that follistatin is relevant to muscle growth. This protein only requires one molecule of either insulin or IGF-1 to have an anabolic effect, and it actually decreases expression of IGF-1. Moreover, follistatin also stimulates the pancreas to produce more insulin, which suggests that the protein has a direct association with insulin signaling. [5]

Follistatin May Improve the chances to Survival in Breast Cancer

The presence of follistatin in breast tumors was examined in a clinical study using reverse transcription polymerase chain reaction (RT-PCR) as well as immune-histochemistry techniques. It was found that follistatin is under-expressed in breast cancer for the most part, but is over-expressed in a small proportion of cases. In the cases where follistatin is over-expressed, tumors grow faster but are less invasive[6]. The presence of follistatin correlates strongly with survival and reduce breast cancer metastasis.

Follistatin has been found to suppress metastasis in a mouse model of HER2-positive breast cancer. Using these mice, researchers found that the protein blocks activin-induced migration of breast epithelial cells, but it is usually absent from the average tumor. Restoring follistatin had an impact on lung metastases and tumor growth[7].

Follistatin is also very important in benign breast conditions, such as fibroadenoma. In this condition, the cells grow rapidly and form benign tumors. The role of follistatin is to boost cell growth while inhibiting the that of fat cells, which encourages them to differentiate into more mature cells[8]. These tumors are often characterized by high levels of FST. Again, this points to a trend that follistatin enhances localized growth while reducing the probability of metastasis.

Follistatin in Esophageal Cancer

Research has identified bone morphogenic protein (BMP) as a causative agent in the transition of normal esophageal tissue to Barrett’s esophagus, a precursor to cancer. It appears that acid reflux over-activates BMP in the esophagus and that counteracting this over-activation, such as through follistatin supplementation, could prevent the development of Barrett’s esophagus in the first place.

When researchers studied breast cancer, they found that the protein BMP misregulation is actually present in colon cancer. For example, impaired BMP signaling is important in the progression of colon cancer. It’s crucial that more research is done on animals, to better quantify how follistatin can be used in fighting against BMP misregulation.

Follistatin Research and Cancer Treatment

Researchers have found that follistatin is active in a number of different cancers, including breast cancer and liver carcinoma. It is hoped that research into the workings of this protein will lead to the development of more cancer treatments. Currently, there is evidence to suggest that when expressed at high levels, follistatin improves survival rates in breast cancer patients, but shortens life in lung, ovarian and gastric cancer patients. By understanding these differences between various types of cancers and studying the impact it may have on their treatment or prognosis, we could learn how to design new treatments or vaccinations that slow or prevent metastasis or help patients survive longer. [9]

Follistatin Associated with Cell Proliferation

Researchers have recently uncovered a dichotomy in the way follistatin works. When located in certain cells, follistatin promotes cell proliferation but restricts metastasis. As it turns out, this is true for most of the body, including the liver. Rat models show that when activin is suppressed by follistatin, proliferation seems to increase. This may explain why follistatin appears to be associated with increased tumor growth without any effect on migration or invasion; energy is being redirected from migration and changed into reproduction instead. [10]

Follistatin Research and Liver Protection

Follistatin has been studied extensively for its potential in the prevention of liver diseases. Studies show that it can be helpful to slow the progression of hepatopathy as a result of early fibrosis, a trait that occur due to the 87% reduction of hepatocellular death in treatment groups. Dysregulation of follistatin has also been linked to the cancerous progression of liver disease. [11] [12]

Follistatin Provides Insight into Congenital Blindness

Research suggests that high levels of TGF-beta proteins, such as BMP (bone morphogenic protein), can suppress optic fusion. By inhibiting these proteins during important developmental periods of pregnancy, optic nerve fusion is made more likely and blindness is reduced. There is basic research into the benefits of follistatin supplementation to ensure that optic nerve fusion takes place during important phase of pregnancy. [13]

Follistatin Research and Hair Growth

Human researches shows that follistatin, specifically when used with other hair-growth stimulants, can improve hair growth significantly. Measurements in a trial of 26 individuals depicted a 20% increase in hair density and a nearly 13% increase in overall thickness. These results remained similar for at least one year following treatment with a single intradermal injection of a follistatin/Wnt- complex[14].

Follistatin Research and Insulin Deficiency and Diabetes

Long-term therapy with follistatin can lead to nearly total prevention of the complications associated with type 1 and type 2 diabetes. By treating diabetic patients, researchers have increased their longevity. The compound works by helping islet cells produce insulin and as a result, blood glucose levels are greatly improved. A form of this treatment may work for both type 1 and type 2 diabetics. This study can lead to long-term improvements with the hopes of preventing or curing diabetes altogether. [15]

The Future of Follistatin Research

Follistatin 344 is a protein with many medical uses. It has low oral and excellent subcutaneous bioavailability in mice. Healthwise, the side effects are moderate but it can be used to treat many diseases. It yields good information about human physiology and may someday yield treatments for several different diseases. Large doses have not yet been tested in humans, and for that reason, Follistatin 344 is sold strictly for research purposes only. If you are looking for follistatin 344 1mg peptide for sale, you will find that this caution is accomplished by adding an extra warning label on our product pages.
