Journal ArticleDOI
Mechanistic and prognostic significance of aberrant methylation in the molecular pathogenesis of human hepatocellular carcinoma
Diego F. Calvisi,Sara Ladu,Alexis Gorden,Miriam Farina,Ju Seog Lee,Elizabeth A. Conner,Insa S. Schroeder,Valentina M. Factor,Snorri S. Thorgeirsson +8 more
TL;DR: The results assign both therapeutic and chemopreventive significance to methylation patterns in human HCC and open the possibility of using molecular targets, including those identified in this study, to effectively inhibit HCC development and progression.
Journal ArticleDOI
Activation of NF‐κB and STAT3 in rat oval cells during 2‐acetylaminofluorene/partial hepatectomy‐induced liver regeneration
Aránzazu Sánchez,Valentina M. Factor,Insa S. Schroeder,Peter Nagy,Peter Nagy,Snorri S. Thorgeirsson +5 more
TL;DR: The differential induction of NF‐κB and STAT3 point to a distinct role for these transcription factors at different stages of hepatic stem cell differentiation.
Journal ArticleDOI
Gene expression profiling in the mammary gland of rats treated with 7,12-dimethylbenz[a]anthracene.
Andriana D. Papaconstantinou,Ilanchezhian Shanmugam,Liang Shan,Insa S. Schroeder,Cunping Qiu,Minshu Yu,Elizabeth G. Snyderwine +6 more
TL;DR: Genes regulating microtubule function, including stathmin, Ran, α‐tubulin and hsp27, were all overexpressed in the mammary gland of DMBA‐treated rats, raising the possibility that disruption of microtubules dynamics and abnormal mitosis may be critical events preceding breast cancer development.
Journal ArticleDOI
Regulation of α-Fetoprotein by Nuclear Factor-κB Protects Hepatocytes from Tumor Necrosis Factor-α Cytotoxicity during Fetal Liver Development and Hepatic Oncogenesis
Lakita G. Cavin,Manickam Venkatraman,Valentina M. Factor,Swayamjot Kaur,Insa S. Schroeder,Frank Mercurio,Amer A. Beg,Snorri S. Thorgeirsson,Marcello Arsura +8 more
TL;DR: NF-κB-mediated regulation of AFP gene expression during liver tumor formation and embryonic development of the liver constitutes a potential novel mechanism used by malignant and fetal hepatocytes to evade immune surveillance.
Journal ArticleDOI
In vitro differentiation of rat liver derived stem cells results in sensitization to TNFα-mediated apoptosis
Aránzazu Sánchez,Valentina M. Factor,Luis A. Espinoza,Insa S. Schroeder,Snorri S. Thorgeirsson +4 more
TL;DR: An efficient antioxidant defense system involving glutathione renders hepatic progenitor cells resistant to TNFα‐mediated apoptosis and acquisition of sensitivity to death stimuli is an implicit feature of the differentiation process.
