OBJECTIVE: Quantify serum TGF\u00df1 and its association to liver collagen content in rats exposed to Carbon Tetrachloride (CCl4). METHODS: Rats were submitted to a fibrosis model using CCl4 and sacrificed after 6, 10, 12 and 16 weeks of treatment. Serum levels of TGF\u00df1 were measured by ELISA and collagen content was defined by morphometric analysis. RESULTS: Serum levels of TGF\u00df1 increased between 6 and 10 weeks, whereas collagen density increased between 12 and 16 weeks. A negative correlation was observed between liver collagen deposition and serum levels of TGF\u00df1 (r = -0. 48; P&lt;0. 05). CONCLUSION: Serum levels of TGF\u00df1 were inversely proportional to collagen intensity in cirrhotic livers of rats exposed to CCl4, thus suggesting a limited use as biomarker in advanced liver disease.<\/jats:p>","DOI":"10.1590\/s0004-28032012000300013","type":"journal-article","created":{"date-parts":[[2012,9,22]],"date-time":"2012-09-22T08:12:12Z","timestamp":1348301532000},"page":"232-234","source":"Crossref","is-referenced-by-count":1,"title":["Relationship
