An approximately 135-bp sequence called the A1/A2 repeat was isolated from the transcribed region of the 26-18S rDNA intergenic spacer (IGS) of Nicotiana tomentosiformis. Fluorescence in situ hybridization (FISH) and Southern blot analysis revealed its occurrence as an independent satellite (termed an A1/A2 satellite) outside of rDNA loci in species of Nicotiana section Tomentosae. The chromoso...

Chromosome 8q24 locus contains regulatory variants that modulate genetic risk to various cancers including prostate cancer (PC). However, the biological mechanism underlying this regulation is not well understood. Here, we developed a chromosome conformation capture (3C)-based multi-target sequencing technology and systematically examined three PC risk regions at the 8q24 locus and their potent...

The present study investigated the effect of zinc-deficiency on chromosomal abnormalities and mitotic index, interaction zinc deficiency methotrexate. Therefore, two zinc-deficient zinc-adequate diet received mice groups were constituted. Methotrexate was injected to one groups. There no structural numerical abnonnalities in all However, index significantly lower than other methotrexate adminis...

Asymmetry in vertical stiffness has been associated with increased injury incidence and impaired performance. The determinants of vertical stiffness asymmetry have not been previously investigated. Eighteen healthy men performed three unilateral drop jumps during which vertical stiffness and joint stiffness of the ankle and knee were calculated. Reactive strength index was also determined durin...

Background : There are growing evidences for chromosomal radioadaptive response in human lymphocytes . Highly variable inter- and intra-individual responses have been reported. Some individuals are non-responders and even in some donors the frequency of chromatid aberrations induced by a challenge dose increases by pre-exposure to an adapting dose. It has been proposed that the lack of radioada...

The activity of the transcription factor sigmaF is confined to one (the forespore) of two cells created by asymmetric division during sporulation in B. subtilis. We show that sigmaF activation is partly governed by the position of the gene for the unstable anti-sigmaF factor SpoIIAB. Because cytokinesis precedes chromosome segregation, most of the chromosome is translocated into the forespore a...

Karyomorphology of 30 species of Papaver L. (Papaveraceae) and in situ localization of rDNA sites on chromosomes of P. somniferum was used to establish phylogenetic affinities, ancestry and chromosomal variation during speciation. A simple biometrical parameter, the ‘Dispersion Index’, was employed to facilitate quantitative evolutionary gradation between the closely related karyotypes that fal...
