    Notes: Abstract  Rhabdomyosarcoma (RMS) is occasionally found in the female genital tract, and mostly appears as one of the heterologous mesenchymal components in uterine carcinosarcoma designated as malignant mixed müllerian tumour (MMMT). We examined the biological properties of a pure rhabdomyosarcoma (RMS) cell line designated FU-MMT-3, which was newly established from a surgical specimen taken from a patient with uterine MMMT. We also evaluated c-myc and MYCN gene amplification in three RMS cell lines (including FU-MMT-3) derived from three MMMTs by Southern blot analysis. FU-MMT-3 cells were propagated continuously for 57 serial passages over a 2-year period in vitro. FU-MMT-3 was able to produce tumours demonstrating pure RMS in athymic nude mice. Cytogenetically, FU-MMT-3 showed a triploidy pattern, with complex karyotypic abnormalities including trisomy of chromosome 8. All three RMS cell lines, including FU-MMT-3, showed amplification of the c-myc gene (approximately fourfold to eightfold), while no cell lines demonstrated MYCN gene amplification. FU-MMT-3 is considered to provide a useful system for the study of the biological behaviour of RMS in MMMTs. Extra copies of chromosome 8 and c-myc gene amplification may be associated with the rhabdomyoblastic differentiation in MMMT.

    Notes: Summary Concentration of cholecystokinin-8 and the activity of glutamic acid decarboxylase were determined in the various cerebral cortical subdivisions of Japanese monkey (Macaca fuscata fuscata) at three different ages (embryonic 4 months, full-term and adult). The CCK-8 immunoreactive material extracted with 90% methanol from the cerebral cortex of the adult and foetal monkey were shown to be identical with synthetic cholecystokinin-8 by the criterion of co-elution on gel filtration chromatography (Sephadex G-50). The peptide concentration increased dramatically by about 30–80 fold (in terms of protein) and 17–28 fold (in terms of wet weight) between embryonic 4-month-old and full-term monkeys, while the level decreased 1/6–1/16 (protein) and 1/4–1/10 (wet weight) between full-term and adult monkeys. In adults, the highest levels of the peptide was observed in the association cortex, orbital prefrontal cortex and posterior parietal cortex. Glutamic acid decarboxylase activity, on the other hand, gradually increased about 4–10 fold (protein) between embryonic 4-month-old and adult animals and there was little variation in the increase rate among the cerebral subdivisions. In contrast to cholecystokinin-8, no reduction in the enzyme activity occurred between full-term and adult animals. The high level of cholecystokinin-8 in the embryonic period suggests that the peptide may participate in the regulation of the development of primate cerebral cortex.

    Molecular cloning of a novel human gene (SIRP-B2) which encodes a new member of the SIRP/SHPS-1 protein family (2000)

    Notes: Abstract A full-length cDNA encoding a novel protein was isolated and sequenced from a human placental cDNA library. This cDNA consists of 1735 base pairs and has a predicted open reading frame (ORF) encoding 354 amino acids. It possesses a putative signal sequence, a long extracellular domain, a transmembrane region, a short intracellular domain, and no catalytic domain, which is highly homologous to signal-regulatory protein (SIRP)-β, suggesting that it seems to be a new member of the SIRP family. Polymerase chain reaction (PCR)-based mapping with both a monochromosomal hybrid panel and radiation hybrid cell panels placed the gene to human chromosome 20p13 near the marker D20S906.
