International Journal of Biochemistry and Cell Biology > 2014 > 53 > Complete > 208-217

Hepatocellular carcinoma (HCC) represents the major histological subtype of liver cancer. Tumorigenic changes in hepatic cells potentially result from aberrant expression of microRNAs (miRNAs). Individual microRNA gene may give rise to miRNAs of different length, named isomiRNAs that proved to be functionally relevant. Since microRNA length heterogeneity in hepatic tissue has not been described before,...

Combination of Morphologic Criteria and α-Fetoprotein in Selection of Patients With Hepatocellular Carcinoma for Liver Transplantation Minimizes the Problem of Posttransplant Tumor Recurrence

Michał Grąt, Oskar Kornasiewicz, Zbigniew Lewandowski, Wacław Hołówko, more

World Journal of Surgery > 2014 > 38 > 10 > 2698-2707

Background Serum α-fetoprotein concentration (AFP) might be a useful addition to morphologic criteria for selecting patients with hepatocellular carcinoma (HCC) for liver transplantation (LT). The aim of this study was to evaluate the role of AFP in selecting HCC patients at minimal risk of posttransplant tumor recurrence in the setting of existing criteria. Methods This retrospective cohort study...

The Enzymatic Activity of Type 1 Iodothyronine Deiodinase (D1) is Low in Liver Hemangioma: A Preliminary Study

Oskar Kornasiewicz, Marcin Debski, Marta Stepnowska, Anna Szałas, more

Archivum Immunologiae et Therapiae Experimentalis > 2010 > 58 > 1 > 77-80

Type 1 iodothyronine deiodinase (D1) is a crucial enzyme which converts the prohormone thyroxine (T4) into active tri-iodothyronine (T3). There has been strong evidence that the metabolism of thyroid hormones is disturbed in some neoplastic tissues such as thyroid, renal, and breast cancer. However, there are few available data about D1 enzyme activity in benign tumors such as hemangioma, which is...
