the karyotype of zagros tooth-carp, aphanius vladykovi (coad) has been investigated byexamining metaphase chromosomes spreads obtained from gill epithelial and kidney cells. the diploidchromosome number of this species was 2n=48. the karyotype consisted of 8 submetacentric and 40subtelocentric chromosomes (8sm+40 st). the arm number (nf) was 28. sex chromosomes werecytologically indistinguishab...
protein tyrosine phosphatases (ptpases) regulate the tyrosine phosphorylation of target proteins in volved in several biological activities including cell proliferation and transformation. protein tyrosine phosphatase e (ptpe) contains duplicated ptpase-like domains and a short extracellular region. us ing the fluorescence in situ hybridization method, the gene encoding ptpe (locus symbol ptpre...
objective: this study determined the chromosomal constitution of recurrent spontaneous abortions by comparative genomic hybridization (cgh) analysis of fetal samples. material and methods: forty pregnant women with early recurrent pregnancy losses aged 21 to 42 years old from tehran university of medical sciences affiliated hospitals entered in this descriptive study. hibridization analysis o...
Drimia is a heterogeneous, poorly understood genus that requires major rearrangement. Chromosome behavior of gigantea and viridula; two species in D. altissima complex was studied for karyotypes transmission extra chromosomes pair pollen viability. Meristematic cells at the root tips viridula were by conventional cytogenetic karyotype analysis. numbers 2n = 22 20 viridula, respectively. Extra c...
The cytogenetic hallmark of Chronic Myeloid Leukemia (CML) is the presence Philadelphia (Ph) chromosome, which results from a reciprocal translocation t(9;22)(q34;q11). In this report, we describe CML patient with no evidence Ph chromosome but trisomy 8 as single abnormality and typical e14a2 (b3a2) BCR-ABL1 fusion transcript. Fluorescence Situ Hybridization (FISH) analysis revealed an uncommon...
