Gene expression pattern in hepatic stem/progenitor cells during rat fetal development using complementary DNA microarrays
Petko M. Petkov, Jiri Zavadil, David Goetz, Tearina Chu, Robert Carver, Charles E. Rogler, Erwin P. Bottinger, David A. Shafritz, Mariana D. Dabeva – 27 February 2004 – To identify new and differentially expressed genes in rat fetal liver epithelial stem/progenitor cells during their proliferation, lineage commitment, and differentiation, we used a high throughput method—mouse complementary DNA (cDNA) microarrays—for analysis of gene expression. The gene expression pattern of rat hepatic cells was studied during their differentiation in vivo: from embryonic day (ED) 13 until adulthood.
Ursodeoxycholic acid protects against secondary biliary cirrhosis in rats by preventing mitochondrial oxidative stress
Gaetano Serviddio, Javier Pereda, Federico V. Pallardó, Julian Carretero, Consuelo Borras, Juan Cutrin, Gianluigi Vendemiale, Giuseppe Poli, José Viña, Juan Sastre – 27 February 2004 – Ursodeoxycholic acid (UDCA) improves clinical and biochemical indices in primary biliary cirrhosis and prolongs survival free of liver transplantation. Recently, it was suggested that the cytoprotective mechanisms of UDCA may be mediated by protection against oxidative stress, which is involved in the development of cirrhosis induced by chronic cholestasis.

Is fibrolamellar carcinoma different from hepatocellular carcinoma? A US population‐based study
Hashem B. El‐Serag, Jessica A. Davila – 27 February 2004 – There have been no population‐based studies of the epidemiology and prognosis of patients with fibrolamellar carcinoma (FLC). We conducted a retrospective cohort study using information collected by population‐based registries of the Surveillance, Epidemiology, and End Results (SEER) program.

Mentink‐Kane – 27 February 2004 – The selectin family of cell adhesion molecules is widely thought to promote inflammatory reactions by facilitating leukocyte recruitment.
Oxysterols induce cyclooxygenase‐2 expression in cholangiocytes: Implications for biliary tract carcinogenesis
Jung‐Hwan Yoon, Ali E. Canbay, Nathan W. Werneburg, Sum P. Lee, Gregory J. Gores – 27 February 2004 – Cyclooxygenase‐2 (COX‐2), which is expressed by cholangiocytes in biliary tract disorders, has recently been implicated in biliary tract carcinogenesis. The mechanisms responsible for this COX‐2 expression remain unclear. In human diseases, bile contains oxygenated derivatives of cholesterol (oxysterols) which possess diverse biological properties. Therefore, we determined if oxysterols modulate COX‐2 expression.
