Autoregulation of interleukin 6 and granulocyte-macrophage colony-stimulating factor in the differentiation of myeloid leukemic cells.

abstract：:B-cell stimulatory factor 2 (BSF-2) is a lymphokine which induces the final maturation of B cells. BSF-2 acts on a variety of cells other than B cells, and moreover, expression of BSF-2 mRNA is detected in interleukin-1 beta-stimulated glioblastoma and astrocytoma cell lines. Here, we studied the function of BSF-2 on ...

abstract：:Insulin-like growth factor II (IGF-II) is a major fetal growth factor. The IGF-II gene generates multiple mRNAs with different 5' untranslated regions (5' UTRs) that are translated in a differential manner during development. We have identified a human family of three IGF-II mRNA-binding proteins (IMPs) that exhibit m...
