DYTOGENETIC ANALYSIS OF HELA AND CHANG CELLS [PDF]

open access: yesIranian Journal of Public Health, 1982
Based on the evaluation of two human cell lines, Hela and Chang, abeuploidy and several marker chromosomes were found in both cells. The morphological characteristic of marker chromosomes of Chang cells was distinctly different from HeLa.

Specific staining of human chromosomes in Chinese hamster x man hybrid cell lines demonstrates interphase chromosome territories [PDF]

open access: yes, 1985
In spite of Carl Rabl's (1885) and Theodor Boveri's (1909) early hypothesis that chromosomes occupy discrete territories or domains within the interphase nucleus, evidence in favor pf this hypothesis has been limited and indirect so far in higher plants ...

A comparative of G-banded chromosome of Assam Macaque (Macaca assamensis) and relationship to human (Homo sapiens) [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2006
This research was the first to report a comparative analysis of G-banded chromosome of Assam macaque, Macaca assamensis (Primate, Cercopithecidae) and relationship to human, Homo sapiens (Primate, Hominidae).

Standard Making in Cytogenetics: the Manufacture, Circulation and Reproduction of Chromosome Images

open access: yesHoST, 2020
The first reliable pattern of the human chromosome set was manufactured between the late 1950s and early 1960s. This paper will account for the historical background of such reliability, of the production of a reference, an image, the schematic figure ...

Determinants of human cyclin B1 association with mitotic chromosomes. [PDF]

open access: yesPLoS ONE, 2013
Cyclin B1-CDK1 activity is essential for mitotic entry, but questions remain regarding how the activity of this kinase is spatially regulated. Previous studies showed that the cyclin B1 subunit localizes to several compartments of a mitotic cell ...

Suitability of a CMV/EGFP cassette to monitor stable expression from human artificial chromosomes but not transient transfer in the cells forming viable clones [PDF]

open access: yes, 2004
Human artificial chromosomes (HACs) were generated by transfer of telomerized PAC constructs containing alpha satellite DNA of various human chromosomes. To monitor which cells took up constructs and subsequently formed stable clones under blasticidin S (

Non-randomness distribution of micro-RNAs on human chromosomes

open access: yesEgyptian Journal of Medical Human Genetics, 2019
Background Micro-RNA (miRNA) is one of the non-coding RNAs that exist in human genome. miRNAs play an important role in the expression of target genes. Several studies have indicated that organization of human genome is not random.

Fluorescence in situ hybridization to chromosomes as a tool to understand human and primate genome evolution [PDF]

open access: yes, 2005
For the last 15 years molecular cytogenetic techniques have been extensively used to study primate evolution. Molecular probes were helpful to distinguish mammalian chromosomes and chromosome segments on the basis of their DNA content rather than solely ...

An analysis of Y-chromosome microdeletion in infertile Korean men with severe oligozoospermia or azoospermia [PDF]

open access: yesInvestigative and Clinical Urology
Purpose: Infertility affects 10% to 15% of couples, and male factor accounts for 50% of the cases. The relevant male genetic factors, which account for at least 15% of male infertility, include Y-chromosome microdeletions.

Characterization of two marker chromosomes in a patient with acute nonlymphocytic leukemia by two-color fluorescence in situ hybridization [PDF]

open access: yes, 1993
A patient with acute nonlymphocytic leukemia (ANLL), M5b according to French-American-British (FAB) classification, showed monosomy 16, an extra 1p−, and a 21q+. These derivative chromosomes could not be defined by GTG-banding.
