Since the expression of glutathione S-transferase P-form (GST-P) has been suggested from in vitro studies to be partly regulated by the oncogene product, c-Jun and c-Fos, their distributions were compared in normal rat tissues and preneoplastic hepatic lesions induced by the Solt-Farber protocol. Immunohistochemically demonstrated GST-P protein was positively correlated with expression of both c-Jun and c-Fos in the epidermis of the skin and the smooth muscle of adult lung and with either c-Jun or c-Fos respectively in the bile ducts and bronchial epithelium. However, GST-P expression was also observed in proximal and distal straight segments of the kidney and other tissues negative for c-Jun and c-Fos and both c-Jun and c-Fos were present in the renal proximal and distal convoluted tubules, where GST-P was lacking. Thus, the localization of GST-P was in some cases clearly separable from those of c-Jun or c-Fos. GST-P was found to be focally expressed from an early stage of hepatocarcinogenesis, when c-Jun was not detectable. At later stages, this oncogene product was stained in 35.7% of GST-P-positive foci, with a clear relation to the degree of GST-P staining. Since GST-P is not always accompanied by appreciable c-Jun or c-Fos, these oncogene products are apparently not prerequisites for its expression. However, c-Jun may be partly responsible for maintaining high levels of GST-P in hepatic foci at later stages of hepatocarcinogenesis.

Meeting's Report -- June 2, 1998, Sugarload Estate Conference Center, Philadelphia, Pennsylvania, USA. A symposium on Normal Development, Oncogenesis and Programmed Cell Death, was held at the Sugarload Estate Conference Center, Philadelphia, Pennsylvania, USA sponsored by the Fels Cancer Institute, Temple University School of Medicine, with the support of the Alliance Pharmaceutical Corporation. The symposium was organized by Drs Dan A Liebermann and Barbara Hoffman at the Fels. Invited speakers included: Dr Andrei V Gudkov (University of Illinois) who started the symposium talking about 'New cellular factors modulating the tumor suppressor function of p53'; Dr Yuri Lazebnik (Cold Spring Harbor Laboratories) spoke about 'Caspases considered as enemies within'; Dr E Premkumar Reddy (Fels Institute, Temple University) talked about recent exciting findings in his laboratory regarding 'JAK-STATs dedicated signaling pathways'; Dr Michael Greenberg (Harvard University) spoke about 'Signal transduction pathways that regulate differentiation and survival in the developing nervous system'; Dr Richard Kolesnick's (Memorial Sloan-Kettering Cancer Center) talk has been focused at 'Stress signals for apoptosis, including Ceramide and c-Jun Kinase/Stress-activated Protein Kinase'; Dr Barbara Hoffman (Fels Institute, Temple University) described research, conducted in collaboration with Dr Dan A Liebermann, aimed at deciphering the roles of 'myc, myb, and E2F as negative regulators of terminal differentiation', using hematopoietic cells as model system. Dr Daniel G Tenen (Harvard Medical School), described studies aimed at understanding the 'Regulation of hematopoietic cell development by lineage specific transcription regulators'. Dr George C Prendergast (The Wistar Institute) talked about the 'Myc-Bin1 signaling pathway in cell death and differentiation. Dr Ruth J Muschel (University of Pennsylvania) spoke about work, conducted in collaboration with Dr WG McKenna, aimed at gaining a better understanding of 'Radioresistance and the cell cycle'. Finally Dr Donald Kufe concluded the symposium (Dana Farber Cancer Institute, Harvard Medical School) describing studies that were performed in his laboratory addressing the 'Role for the c-Abl tyrosine kinase in genetic recombination'.
