Bladder Tumours

During this last decade, flow cytometry (FCM) has been widely investigated and employed in assessing the DNA content of bladder tumours. The prognostic value of FCM is recognised by the majority of investigators, above all when it concerns superficial transitional cell carcinoma of the bladder. The determination of ploidy and the degree of aneuploidy seem to offer valuable prognostic information. The Authors have reviewed Literature on this subject, identifying three different categories of studies that analyse the relation of FCM to cytohystological characterisation, to the clinical behaviour of the tumours and to the patients’ survival.

Flow cytometry (FC) has proven to be an efficient and reliable method to estimate nuclear DNA content (genome size) in quantifiable units useful for genetic and molecular biology studies. This method also makes possible determination of the variation in nuclear DNA content between related taxa, which gives insights into the process of speciation. In this study, DNA content was determined in nuclei isolated from leaves of 21 Dendrobium species representing each of the major taxonomic groups used in the Univ. of Hawaii breeding program. Nuclei were mechanically isolated, stained with the nucleic acid-specific fluorochrom propidium iodide, and DNA content determined using a Coulter Epics 753 laser flow cytometer. Chicken erythrocyte nuclei (2C = 2.33 pg DNA) were used as an internal standard for direct comparative measurement. The mean diploid genome (2C) values for Dendrobium species ranged from 3.36 to 5.06 pg. Genome sizes were evaluated for possible use as discrete characters for taxonomic group assignment and compared to previous data on breeding compatibility and evolutionary relationship between species.

Isolated nuclei from cereal plants were used for quantitative determination of DNA per nucleus by flow cytometry. The technique is based on enhanced fluorescence of ethidium bromide and olivomycin when they bind to DNA. Nuclei were isolated from protoplasts derived from leaves of seedlings. The diploid Hordeum vulgare cv. Trumpf was used as an internal standard. Analysis of nuclei from several cultivars of hexaploid wheat (Triticum aestivum), Triticum durum var. hordeiforme, T. durum var. alexandrinum, Triticum araraticum, Triticum timopheevi, Triticum monococcum, Aegilops speltoides, Secale cereale, and one hexaploid and one octoploid triticale revealed significant intra- and inter-specific differences in DNA values per 2C nucleus. The advantages of the procedure are discussed along with its utilization for quantitative DNA measurement in Gramineae.Key words: nuclear isolation, flow cytometry, DNA content, cereals.

AbstractThe DNA content per diploid nucleus (2 C-value) was determined for the eight species of Iberian salamanders by flow cytometry. All species showed high values, which are characteristic of Caudata. The species with the lowest value was Pleurodeles waltl (48.25 pg DNA/cell) and Salamandra salamandra had the highest values (70.55 pg DNA/cell). There were no statistical differences between sexes in any of the eight species and DNA content was not directly related with phylogeny. The values obtained are often higher than previously published estimates obtained with older and potentially less accurate methodologies. We discuss the possible relationship between cellular DNA content and reproductive biology. Se determinó el contenido en ADN por núcleo diploide (valor 2-C) por citometría de flujo de ocho especies de salamandras ibéricas. Todas las especies mostraron altos valores, lo que es característico de Caudata. La especie con el menor valor fue Pleurodeles waltl (48,25 pg ADN/célula) mientras Salamandra salamandra tuvo las valores más altos (70,55 pg ADN/célula). No se encontraron diferencias estadísticas entre sexos en ninguna de las 8 especies y el contenido en ADN no se relacionó directamente con la filogenia. Los valores obtenidos son, a menudo, más altos que los publicados previamente con técnicas más antigüas, y potencialmente menos precisas. Discutimos las posibles relaciones entre el contenido en ADN celular y la biología reproductiva de cada especie.
