  author={Nusret Akpolat and Seyfettin Yahşi and Ahmet Godekmerdan and Mehmet Yalnız and Kutbettin Demirbag},
Aims : To investigate the value of α‐smooth muscle actin (α‐SMA), an indicator of stellate cell activation, in predicting fibrosis in chronic hepatitis B (CHB) patients. 

α-SMA and Ki-67 immunohistochemistry as indicators for the fibrotic remodeling process in the liver of dogs.

Investigating the expression of two immunohistochemical markers in liver diseases with and without fibrosis in dogs concluded that Ki-67 and a-SMA can be potentially used as markers for the fibrotic remodeling of the liver.

Value of α-smooth muscle actin and glial fibrillary acidic protein in predicting early hepatic fibrosis in chronic hepatitis C virus infection

Glial fibrillary acidic protein could represent a more useful marker than α-SMA of early activation of HSCs in CHC patients and seems to be an early indicator of hepatic fibrogenesis.

Bevacizumab as a potential anti‐angiogenic therapy in schistosomiasis: A double‐edged, but adjustable weapon

Investigating the anti‐angiogenic effect of bevacizumab on chronic schistosomiasis mansoni in a trial to hinder the Schistosome‐induced angiogenesis and porto‐systemic shunting complications.

Activated liver stellate cells in chronic viral C hepatitis: histopathological and immunohistochemical study.

An increased number of activated hepatic stellate cells within portal spaces and fibrous septa may be a useful prognostic marker for the development of advanced fibrosis and cirrhosis in chronic C hepatitis.

β-Actin: Not a Suitable Internal Control of Hepatic Fibrosis Caused by Schistosoma japonicum

It is found that the expressions of both β-actin mRNA and protein increased significantly with hepatic fibrosis formation after 6 weeks infection with Schistosoma japonicum and kept high level during the progression of hepatic Fibrosis, while the levels of β-Tubulin and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) remained stable.

[Immunohistochemical analysis of alpha-SMA and GFAP expression in liver stellate cells].

This study showed the existance of two different stellate cell subpopulations in liver tissue, and differentiation between them was possible on the basis of SMA/GFAP expression.

Therapeutic effects of vitamin A on experimental cholestatic rats with hepatic fibrosis

Although most of the data are qualitative observation, vitamin A may ameliorate hepatic fibrosis in the BDL model by restoring vitamin A in the HSCs.

The fibrosis progression, and treatment of the NCU-G1gt/gt mouse model

The fibrosis progression in the NCU-G1 mice is investigated with gene expression, protein and liver component analyses, and with treatment with the anti-fibrotic agent sodium hydrogen sulfide (NaHS) is attenuated.

Activated hepatic stellate cells are the crucial factor responsible for liver fibrosis and involved in development of hepatocellular carcinoma (HCC) by interaction with tumour cells.

Origin and function of myofibroblasts in the liver.

The hypothesis that each fibrogenic cell population in the liver exerts specific functions is discussed, and whether cell type-specific antifibrotic strategies are required or whether one therapeutic strategy fits all is discussed.



Expression of SPARC by activated hepatic stellate cells and its correlation with the stages of fibrogenesis in human chronic hepatitis

The present results indicate that SPARC is expressed by activated HSCs in chronic hepatitis, suggesting the involvement of SPARC in hepatic fibrogenesis after chronic injuries.

Classification of chronic hepatitis: Diagnosis, grading and staging

Recombinant human alpha-interferon in patients with chronic nonA-nonB hepatitis and factors predictive of response to interferon alpha therapy in HCV infection are studied.

The Cellular Basis of Hepatic Fibrosis -- Mechanisms and Treatment Strategies

Advances in the isolation and characterization of liver cells, in conjunction with progress in matrix and cytokine biology, have led to important new insights about the cellular basis of hepatic fibrosis, including the hepatic lipocyte.

Hepatic stellate cells as a target for the treatment of liver fibrosis.

The design of promising new antifibrotic therapies aimed at inhibiting the accumulation of activated HSCs at the sites of liver injury and preventing the deposition of extracellular matrix are described.

Diagnostic Liver Pathology

This book discusses Liver Transplantation Cysts and Fibrocystic Diseases Neoplasms and Other Masses, as well as other diseases and disorders related to liver transplants and organ transplantation.

Stromal mast cells and nerve fibers in various chronic liver diseases: relevance to hepatic fibrosis

The results suggest that mast cells and nerve fibers are involved in fibrogenesis in chronic liver diseases, regardless of their etiologies, probably by secreting fibrogenic substances.

Transcriptional regulation of hepatic stellate cell activation

The hepatic stellate cell (HSC) is now well established as the key cellular element involved in the development of hepatic fibrosis and because of this there is considerable interest in establishing
