Novel hepatocyte growth factor/scatter factor isoform transcripts in the macaque endometrium and placenta

Hepatocyte growth factor/scatter factor (HGF/SF) induces proliferation, motility and morphogenesis of cells that express the proto-oncogene for the tyrosine kinase receptor, c-Met.

Description
Summary:Hepatocyte growth factor/scatter factor (HGF/SF) induces proliferation, motility and morphogenesis of cells that express the proto-oncogene for the tyrosine kinase receptor, c-Met. Because these cellular events occur in the endometrium during the menstrual cycle and in placenta during development, we have initiated studies of this growth factor in these tissues from macaques. Several HGF/SF alternatively spliced transcripts have been previously reported in other tissues. However, expression of HGF/SF isoforms in the endometrium has not been studied. Here we describe the relative transcript amounts of HGF/SF isoforms in the endometrium and placenta using RNase protection analyses. During these analyses, we discovered two unexpected protected bands that were found through sequence analyses to represent isoforms similar to the previously reported NK1 and NK2 except that they encode a five amino acid deletion in the first kringle domain. We designated these two isoforms as dNK1 and dNK2. Endometrium expressed all of the isoforms; however, dNK2 was consistently expressed at higher levels than NK2 transcripts. In contrast, placenta expressed NK2 and dNK2 mRNA at equal levels, and both NK1 and dNK1 were undetectable in placenta. HGF/SF function in endometrium and placenta may involve complex interactions between the isoforms of HGF/SF and those of c-Met.
