Cytogenetic studies on prolymphocytic leukemia. II. T cell prolymphocytic leukemia.
We report chromosome abnormalities in 15 cases of T cell prolymphocytic leukemia (T-PLL). All cases were characterized by clinical, morphological, and membrane marker analysis. The most frequent abnormality was an inv(14)(q11q32) observed in nine cases. The T cell receptor (TCR) alpha chain gene is localized to 14q11 and the immunoglobulin heavy-chain gene to region 14q32. Four cases also had t...
متن کاملCytogenetic Studies on Triticale. I. a Method for Determining the Effects of Individual Secale Chromosomes on Triticum.
H E production of fertile, true-breeding hybrids which combine the T characters of two different species or genera has proven to be of theoretical and practical importance. These hybrids have usually arisen through a doubling of the chromosome complement following the initial cross, this doubling resulting in the presence in the fertile hybrid of two full complements from each parent. Such plan...
متن کاملMolecular cytogenetic characterization of a new leaf rolling triticale.
Leaf rolling occurs in some cereal genotypes in response to drought. We identified and made a phenotypic, cytological and physiological analysis of a leaf-rolling genotype (CMH83) of hexaploid triticale (X Triticosecale Wittmack) that exhibited reduced plant height, rolled and narrow leaves. Gliadin electrophoresis of seed protein showed that CMH83 was genetically stable. Sequential Giems...
متن کاملImpact of cytogenetic and molecular cytogenetic studies on hematologic malignancies.
Conventional cytogenetic analysis of chromosome abnormalities in hematologic malignancies is hampered by the low mitotic index and poor quality of metaphases. A range of techniques based on fluorescence in situ hybridization (FISH) has greatly enhanced the identification of non-random translocations and deletions, pinpointing regions which contain genes involved in leukemogenesis. One of the ma...
متن کاملCytogenetic studies on Gonatodes (Reptilia, Squamata, Sphaerodactylidae).
Mitotic and meiotic chromosomes of 5 species of the reptile genus Gonatodes are described by means of conventional staining, banding analyses and in situ hybridization using a synthetic telomeric DNA probe. The amount, location and fluorochrome affinities of constitutive heterochromatin, the number and positions of nucleolus organizer regions, and the patterns of telomeric DNA sequences were de...
