Dosage Sensing, Threshold Responses, and Epigenetic Memory: A Systems Biology Perspective on Random X‐Chromosome Inactivation

, 2020
X‐chromosome inactivation ensures dosage compensation between the sexes in mammals by randomly choosing one out of the two X chromosomes in females for inactivation.

Genomic catastrophes frequently arise in esophageal adenocarcinoma and drive tumorigenesis [PDF]

, 2014
Oesophageal adenocarcinoma (EAC) incidence is rapidly increasing in Western countries. A better understanding of EAC underpins efforts to improve early detection and treatment outcomes.

Chromosomal Gains and Losses in Uveal Melanomas Detected by Comparative Genomic Hybridization [PDF]

, 1994
Eleven uveal melanomas were analyzed using comparative genomic hybridization (CGH). The most abundant genetic changes were loss of chromosome 3, overrepresentation of 6p, loss of 6q, and multiplication of 8q.

Detection of fluorescence in situ hybridization on human metaphase chromosomes by near-field scanning optical microscopy [PDF]

, 1995
Fluorescence in situ hybridization signals o­n human metaphase chromosomes are detected by a near-field scanning optical microscope. This makes it possible to localize and identify several fluorescently labeled genomic DNA fragments o­n a single ...

Massive gene amplification on a recently formed Drosophila Y chromosome. [PDF]

, 2019
Widespread loss of genes on the Y is considered a hallmark of sex chromosome differentiation. Here we show that the initial stages of Y evolution are driven by massive amplification of distinct classes of genes. The neo-Y chromosome of Drosophila miranda

Chromatin accessibility underlies synthetic lethality of SWI/SNF subunits in ARID1A-mutant cancers. [PDF]

, 2017
ARID1A, a subunit of the SWI/SNF chromatin remodeling complex, is frequently mutated in cancer. Deficiency in its homolog ARID1B is synthetically lethal with ARID1A mutation.

Increased serum extrachromosomal circular DNA SORBS1circle level is associated with insulin resistance in patients with newly diagnosed type 2 diabetes mellitus

Cellular & Molecular Biology Letters
Background Extrachromosomal circular DNAs (eccDNAs) exist in human blood and somatic cells, and are essential for oncogene plasticity and drug resistance. However, the presence and impact of eccDNAs in type 2 diabetes mellitus (T2DM) remains inadequately

Uncovering Proximity of Chromosome Territories using Classical Algebraic Statistics [PDF]

, 2014
Exchange type chromosome aberrations (ETCAs) are rearrangements of the genome that occur when chromosomes break and the resulting fragments rejoin with other fragments from other chromosomes.

Differences of size and shape of active and inactive X-chromosome domains in human amniotic fluid cell nuclei [PDF]

, 1993
It is a widely held belief that the inactive X-chromosome (Xi) in female cell nuclei is strongly condensed as compared to the largely decondensed active X-chromosome (Xa).
