Validation of the S-phase specificity of histone (H3) in situ hybridization in normal and malignant cellsAM Gown, JJ Jiang, H Matles, M Skelly, T Goodpaster, L Cass, M Reshatof, D Spaulding and MD Coltrera Department of Pathology, University of Washington, Seattle, USA. Several different methods of measuring proliferation indices have been developed, including measurements of cellular DNA content (flow cytometry), S-phase incorporation of thymidine analogues into DNA (e.g., tritiated thymidine and 5'-bromodeoxyuridine), and immunostaining of cell cycle-restricted proteins (e.g., Ki-67 antigen and PCNA). Theoretical and practical problems with each method have made it difficult to compare absolute proliferation rates among cells of different lineages and degrees of malignancy. More recently, in situ hybridization (ISH) for histone 3 (H3) mRNA has been introduced. We used a double labeling method for comparing H3 mRNA expression and S- phase incorporation of 5'-bromodeoxyuridine (BrdU) to determine if H3 mRNA expression was tightly associated with S-phase in a variety of malignant and nontransformed cell types. In addition, labeling results were compared in methacarn- and formalin-fixed tissues to extend the potential usefulness of H3 ISH, using a postfixation technique for the alcohol-fixed specimens. As expected for a cumulative marker, variation was noted in the percentage of the BrdU-positive cells double labeled with H3 ISH (53-89%), depending on cell type and length of BrdU incubation. In contrast, the percentage of the H3 ISH-positive cell population double labeled for BrdU was independent of the cell type of BrdU incubation time (mean 78%). Similarly, a consistent percentage of H3 ISH-positive cell populations was double labeled for BrdU in normal tissues (mean 97%). These findings support a well-conserved timing mechanism for H3 mRNA expression and DNA replication. We conclude that H3 ISH is an extremely accurate technique for assessment of S-phase cell proliferation indices.
