AIM: To investigate the transforming growth factor-β (TGF-β) isoforms in the peripheral and hepatic venous blood of primary biliary cirrhosis (PBC) patients. METHODS: We examined TGF-β1, TGF-β2 and TGF-β3 (enzyme-linked immunosorbent assay), in 27 stage Ⅳ PBC patients (27 peripheral and 15 hepatic vein sera), 35 early (Ⅰ-Ⅱ) PBC and 60 healthy controls. As disease controls 28 hepatitis C virus (HCV) cirrhosis (28 peripheral and 17 hepatic vein serum), 44 chronic HCV hepatitis and 38 HCV-related hepatocellular carcinomas were included. We also tested liver tissue by immunohistochemistry to identify localization of TGF isoforms. RESULTS: TGF-β1 was significantly decreased in all cirrhotics (PBC Ⅲ-Ⅳ: median 13.4 ng/mL; range, 7.4-26.2, HCV cirrhosis: 11.6 ng/mL; range, 5.0-33.8), compared to controls (30.9 ng/mL; range, 20.9-37.8). TGF-β2 was increased in viral cirrhosis but not in PBC and chronic hepatitis. TGF-β3 (47.2 pg/mL; range, 27.0-79.7 in healthy controls) was increased in early and late PBC (Ⅰ-Ⅱ: 94.3 pg/mL; range, 41.5-358.6; Ⅲ-Ⅳ: 152.8 pg/mL; range, 60.4-361.2; P < 0.001) and decreased in viral cirrhosis (37.4 pg/mL; range, 13.3-84.0; P < 0.05). Hepatic vein TGF-β levels were analogous to those in peripheral blood. Immunohistochemistry identified all isoforms in portal tract lymphocytes, sinusoidal cells and cholangiocytes. TGF-β3 was additionally overexpressed in hepatocytes in PBC patients. CONCLUSION: The serum profile of TGF-β isoforms is different in cirrhotics. Increased TGF-β3 is characteristic of PBC. These findings may be related to the immunological abnormalities of PBC.

Dear Editor,Hepatic stellate cells(HSCs)play a key role in the fibrotic response,thus inactivating activated HSC could be a potential therapy for fibrosis.^(1,2) CCL20 expressed by HSCs and macrophages,may serve as a mediator of in flammation and fibrosis.^(3) LIX1L is a putative RNA-binding protein(RBP)that may play an important role in post-transcriptional gene regulation.^(4) However,the biological function of LIX1L in liver fibrosis remains unclear,we therefore aimed to characterize its functions in HSC activation and liver fibrosis.

Background: Osteoblastoma, a rare osteoblastic tumor, constitutes approximately 1% of all primary bone tu- mors. Aim: The purpose of this report is to present an osteoblastoma of the mandible, with particular emphasis on the differential diagnosis of this rare tu- mor. Methods-Results: the lesion showed osteoblast- like cells, stromal cells, osteoclast-like cells and inter- lacing trabeculae of osteoid. Because of the high cel- lularity of the tumor, immunohistochemical analysis was performed using the cell proliferation marker Ki-67, the p53 and the anti-apoptotic protein Bcl-2. The lesion demonstrated low to moderate prolifera- tive activity and no immunoreactivity was detected for p53. An interesting finding was the Bcl-2 expres- sion by the multinucleated osteoclast-like giant cells, in contrast to the lack of Bcl-2 expression from osteo- blast-like and stromal tumor cells. Conclusion: To our knowledge the Bcl-2 expression has not yet been in- vestigated in benign or malignant osteoblastic tumors. This finding may be related to the molecular mecha- nisms regulating the apoptosis of osteoclast-like tu- mor cells or their function.
