Deutsches Krebsforschungszentrum, Abteilung Cytopathologie, Heidelberg, Germany
Toxicol Pathol 23:591-605. 1995..Mitochondrial proliferation as the most prominent feature in all stages of this model of hepatocarcinogenesis may offer a new approach for analysis of hepatocarcinogenesis induced by DHEA and possibly other peroxisomal proliferators...
Activity of glycogen synthase and phosphorylase and glucose 6-phosphate content in renal clear cell carcinomasD Mayer
Institut für Experimentelle Pathologie, Deutsches Krebsforschungszentrum, Heidelberg, Federal Republic of Germany
J Cancer Res Clin Oncol 114:369-72. 1988..These findings agree with those in some other glycogenotic tissues and support the concept that an accumulation of G6P is associated with excessive storage of glycogen in preneoplastic and neoplastic lesions...
Re-evaluation of the specificity of adenylyl (beta,gamma-methylene)diphosphonate as a substrate for adenylate cyclaseD Mayer
Abteilung Cytopathologie, Deutsches Krebsforschungszentrum, Heidelberg, FRG

Dehydroepiandrosterone stimulates proliferation and gene expression in MCF-7 cells after conversion to estradiolM Schmitt
Research Group 'Hormones and Signal Transduction, Division of Signal Transduction and Growth Control, Deutsches Krebsforschungszentrum, Im Neuenheimer Feld 280, 69120, Heidelberg, Germany
Mol Cell Endocrinol 173:1-13. 2001..An androgenic effect of DHEA on proliferation and gene expression of MCF-7 cells was not observed. We conclude that conversion of DHEA to estrogens, particularly estradiol, is required to exert a mitogenic response...
