X chromosome inactivation during Drosophila spermatogenesis. [PDF]

PLoS Biology, 2007
Genes with male- and testis-enriched expression are under-represented on the Drosophila melanogaster X chromosome. There is also an excess of retrotransposed genes, many of which are expressed in testis, that have "escaped" the X chromosome and moved to ...

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

, 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 ...

Comparative chromosome painting discloses homologous Segments in distantly related mammals [PDF]

, 1994
Comparative chromosome painting, termed ZOO-FISH, using DNA libraries from flow sorted human chromosomes 1,16,17 and X, and mouse chromosome 11 discloses the presence of syntenic groups in distantly related mammalian Orders ranging from primates (Homo

Partial dosage compensation in Strepsiptera, a sister group of beetles. [PDF]

, 2015
Sex chromosomes have evolved independently in many different taxa, and so have mechanisms to compensate for expression differences on sex chromosomes in males and females. Different clades have evolved vastly different ways to achieve dosage compensation,

A case of acute lymphoblastic leukemia with additional chromosomes X and 5 associated with a Philadelphia chromosome in the bone marrow

Turkish Journal of Hematology, 2010
We report herein a very rare case of acute lymphoblastic leukemia having a chromosomal constitution of 48,XY,+X,+5,t(9;22)(q34;q11) in the bone marrow.

Deciphering the Role of the Barr Body in Malignancy: An insight into head and neck cancer

Sultan Qaboos University Medical Journal, 2018
X chromosome inactivation is the epitome of epigenetic regulation and long non-coding ribonucleic acid function. The differentiation status of cells has been ascribed to X chromosome activity, with two active X chromosomes generally only observed in ...

Detectable chromosome X mosaicism in males is rarely tolerated in peripheral leukocytes

Scientific Reports, 2021
Age-related male Y and female X chromosome mosaicism is commonly observed in large population-based studies. To investigate the frequency of male X chromosome mosaicism, we scanned for deviations in chromosome X genotyping array intensity data in a ...

Large-Scale Analysis of X Inactivation Variations between Primed and Naïve Human Embryonic Stem Cells

Cells, 2022
X chromosome inactivation is a mammalian dosage compensation mechanism, where one of two X chromosomes is randomly inactivated in female cells. Previous studies have suggested that primed human embryonic stem cells (hESCs) maintain an eroded state of the

On a break with the X: the role of repair of double-stranded DNA breaks in X-linked disease [PDF]

, 2012
The problem of managing free reactive DNA ends in eukaryotic cells has resulted in the development of a number of mechanisms in order to ensure that free ends are rendered non-reactive, or that the double-strand DNA breaks generating the free ends are ...

Variation of autosomes and X chromosome STR in breast cancer and gynecological cancer tissues

Open Life Sciences, 2017
This study analyses 1000 cases of patients with breast cancer and 2000 cases of patients with gynecological cancer (1000 cases of malignant tumor, 1000 cases of benign tumors), where breast cancer and malignant tumor patients comprise the observation ...
