Taurine

The studies here refer to taurine being used to treat inflammatory processes as well as fibrosis. It may not translate to peyronie's disease, but it appears to be useful in lung, liver and pancreatic fibrosis in rats. This does not necessarily mean the same level of success will transfer across to humans for even these conditions, but we can only go on the information we possess.

[Taurine inhibits deposition of extracellular matrix in experimental liver fibrosis in rats]

To study the effect of taurine on liver fibrosis and its mechanism. METHODS: Fibrosis was induced by the administration of carbon tertrachloride(CCl4) in rats. Some of the animals were treated with taurine. The rats were killed after 12 weeks of CCl4 treatment. Depositions of type I, III and IV collages, laminin and hyaluronic acid were studied in liver sections by immunohistochemical technique using specific antibody. The hepatic contents of type I, III procollage and tissue inhibitor of metalloproteinase-1(TIMP-1) mRNA were determined by Northern blot hybridization. RESULTS: A significant elevations of hepatic collagen I, III, IV, laminin and hyaluronic acid were observed after 12 weeks of liver injury in animals without taurine treatment, and a definite increase in the amounts of hepatic type I, III procollagen and TIMP-1 mRNA was noted. Taurine prevented increases in type I, III procollagen mRNA expression as well as the accumulation of the collagens, laminin and hyaluronic acid in the liver. CONCLUSION: The data indicate that taurine has a protective effect in CCl4-induced hepatic fibrosis. The results suggest taurine might be of potential value in clinical practice.

[Oral administration of taurine improves experimental pancreatic fibrosis]

BACKGROUND AND AIM: The mechanism of pancreatic fibrosis is unclear. Taurine is used in the clinical treatment of a wide variety of diseases, but its effect on improving pancreatic fibrosis is unknown. We examined whether a diet with added taurine improves pancreatic fibrosis induced by dibutyltin dichloride (DBTC) in an experimental chronic pancreatitis rat model. In addition, we examined the influence of taurine on pancreatic stellate cells. METHODS: Pancreatic fibrosis was induced by DBTC. Rats were fed a taurine-containing diet or a normal diet and were killed at 4 weeks. Pancreatic stellate cells were isolated from male Wistar rats. Cultured pancreatic stellate cells were incubated with or without taurine chloramine. Type I collagen and transforming growth factor-beta1 secretion was evaluated by ELISA, and matrix metalloproteinase activity was assessed by gelatin zymography. Interleukin-6, interleukin-2, and transforming growth factor-beta1 levels in the supernatants of pancreatic tissue homogenates were measured. RESULTS: Pancreatic fibrosis induced by DBTC was improved remarkably by the oral administration of the taurine-containing diet. Taurine chloramine decreased type I collagen, transforming growth factor-beta1, and matrix metalloproteinases 2 of the pancreatic stellate cell culture supernatant. Increased interleukin-6 and decreased interleukin-2 were found in the supernatants of the pancreatic tissue homogenates of DBTC-induced pancreatitis rats compared with other groups. CONCLUSION: The oral administration of taurine improves pancreatic fibrosis. Taurine chloramine inhibits transforming growth factor-beta1 produced from activated pancreatic stellate cells and improves pancreatic fibrosis.

[Taurine attenuates radiation-induced lung fibrosis in C57/Bl6 fibrosis prone mice]

INTRODUCTION: The amino acid taurine has an established role in attenuating lung fibrosis secondary to bleomycin-induced injury. This study evaluates taurine's effect on TGF-beta1 expression and the development of lung fibrosis after single-dose thoracic radiotherapy. METHODS: Four groups of C57/Bl6 mice received 14 Gy thoracic radiation. Mice were treated with taurine or saline supplementation by gavage. After 10 days and 14 weeks of treatment, TGF-beta1 levels were measured in serum and bronchoalveolar lavage fluid (BALF). Lung collagen content was determined using hydroxyproline analysis. RESULTS: Ten days post radiotherapy, serum TGF-beta1 levels were significantly lower after gavage with taurine rather than saline (P = 0.033). BALF TGF-beta1 at 10 days was also significantly lower in mice treated with taurine (P = 0.031). Hydroxyproline content was also significantly lower at 14 weeks in mice treated with taurine (P = 0.020). CONCLUSION: This study presents novel findings of taurine's role in protecting from TGF-beta1-associated development of lung fibrosis after thoracic radiation.- http://www.ncbi.nlm.nih.gov/pubmed/19609640



I certainly wouldn't suggest taurine as a primary treatment for peyronie's because there are much more established oral treatments out there such as the PAV cocktail (Pentoxifylline, L-Arginine and Viagra). However, it may be of use as part of a wider regime. It's certaily not something I'd dissuade anybody in early stage peyronie's disease from taking.

A note of caution, beta-alanine and carnosine are known to induce taurine deficiency, so if you are taking those supplements, you may need to factor that in.
