Haplotype analysis of the X chromosome in patients with Turner syndrome in order to verify the possible effect of imprinting on selected symptoms

open access: yesBiomedical Papers, 2022
Aims. Turner syndrome is the only chromosome monosomy that is postnatally compatible with life. The reported incidence of TS is 1 in 2500 liveborn girls.

Digital karyotyping [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
Alterations in the genetic content of a cell are the underlying cause of many human diseases, including cancers. We have developed a method, called digital karyotyping, that provides quantitative analysis of DNA copy number at high resolution. This approach involves the isolation and enumeration of short sequence tags from specific genomic loci ...

Karyotype evolution in Fusarium [PDF]

open access: yesIMA Fungus, 2018
The germ tube burst method (GTBM) was employed to examine karyotypes of 33 Fusarium species representative of 11 species complexes that span the phylogenetic breadth of the genus. The karyotypes revealed that the nucleolar organizing region (NOR), which includes the ribosomal rDNA region, was telomeric in the species where it was discernible.

Comparative Study on the Karyotype of Two Species of Megaulacobothrus Caud., 1921 (Acridoidea) [PDF]

open access: yesMongolian Journal of Biological Sciences, 2013
The karyotypes of Chorthippus ( Megaulacobothrus ) aethalinus (Zubovsky, 1899) and Chorthippus ( Megaulacobothrus ) chinensis Tarbinsky, 1927 were compared by means of the conventional cytogenetic method.

Analysis of muntjac deer genome and chromatin architecture reveals rapid karyotype evolution

open access: yesCommunications Biology, 2020
Closely related muntjac deer show striking karyotype differences. Here we describe chromosome-scale genome assemblies for Chinese and Indian muntjacs, Muntiacus reevesi (2 n  = 46) and Muntiacus muntjak vaginalis (2 n  = 6/7), and analyze their evolution

Evolution of Karyotypes in Chameleons [PDF]

open access: yesGenes, 2017
The reconstruction of the evolutionary dynamics of karyotypes and sex determining systems in squamate reptiles is precluded by the lack of data in many groups including most chameleons (Squamata: Acrodonta: Chamaeleonidae). We performed cytogenetic analysis in 16 species of chameleons from 8 genera covering the phylogenetic diversity of the family and ...

First constitutive heterochromatin characterization and Karyotype of white stork Ciconia ciconia (Aves: Ciconiidae)

open access: yesBrazilian Journal of Biology, 2021
The karyotype and constitutive heterochromatin pattern of the white stork Ciconia ciconia samples obtained from Manzala lake, Dimiaat, Egypt was described. Somatic cells of Ciconia ciconia samples have diploid number 2n= 68 chromosomes.

Cytoplasmic nucleophosmin in acute myelogenous leukemia with a normal karyotype.

open access: yesNew England Journal of Medicine, 2005
BACKGROUND Nucleophosmin (NPM), a nucleocytoplasmic shuttling protein with prominent nucleolar localization, regulates the ARF-p53 tumor-suppressor pathway.

The karyotype of the pig

open access: yesHereditas, 2009
The karyotype of the pig (Sus scrofa domestica) is studied and characterized after applying G-band and C-band staining procedures. The material examined originates from 5 boars and 5 gilts and consists of cells from fibroblast and lymphoblast cultures. The identity of the X-chromosome is discussed.

Karyomorphometry on three polyploid species of Arum L. (Araceae, Aroideae)

open access: yesComparative Cytogenetics, 2014
In this study three polyploid Arum Linnaeus, 1753 species from Southern Italy were chromosomally investigated. Arum italicum Miller, 1768 was found to have 2n = 84 chromosomes and a karyotype composed of numerous asymmetric chromosomes.
