Molecular Oncology, EarlyView.This study develops a semi‐supervised classifier integrating multi‐genomic data (1404 training/5893 validation samples) to improve homologous recombination deficiency (HRD) detection in breast cancer. Our method demonstrates prognostic value and predicts chemotherapy/PARP inhibitor sensitivity in HRD+ tumours.

Movement of X Chromosome in Epileptic Cortex
Pediatric Neurology Briefs, 1989 Chronic uncontrolled seizure activity was linked to specific positional changes of the X chromosome in neurons of cortical seizure foci from both male and female patients at Yale University School of Medicine, New Haven, Connecticut.

Mechanics and Dynamics of X-Chromosome Pairing at X Inactivation [PDF]
PLoS Comp.Bio. 4, e1000244 (2008), 2009 At the onset of X Chromosomes Inactivation, the vital process whereby female mammal cells equalize X products with respect to males, the X chromosomes are colocalized along their Xic (X-Inactivation Center) regions. The mechanism inducing recognition and pairing of the X's remains, though, elusive.

When is Menzerath-Altmann law mathematically trivial? A new approach [PDF]
, 2012 Menzerath's law, the tendency of Z, the mean size of the parts, to decrease as X, the number of parts, increases is found in language, music and genomes. Recently, it has been argued that the presence of the law in genomes is an inevitable consequence of the fact that Z = Y/X, which would imply that Z scales with X as Z ~ 1/X.

CINs of the cytoplasm: dissecting dsRNA signaling in chromosomal instability
Molecular Oncology, EarlyView.Micronuclei, formed during cell division in chromosomal instability settings, rupture and lead to the accumulation of immunogenic double‐stranded RNA in the cytoplasm, activating MAVS‐dependent interferon signaling and innate antitumor immunity.

European Medical Journal, 2017 Many autoimmune diseases, such as lupus and Sjögren’s syndrome, have a female bias and adult onset. One possible explanation for this bias is disruption of the inactive X chromosome, which is a major epigenetic feature in female cells. Indeed, only one X

Strong selective sweeps associated with ampliconic regions in great ape X chromosomes [PDF]
arXiv, 2014 The unique inheritance pattern of X chromosomes makes them preferential targets of adaptive evolution. We here investigate natural selection on the X chromosome in all species of great apes. We find that diversity is more strongly reduced around genes on the X compared with autosomes, and that a higher proportion of substitutions results from positive ...

Human Molecular Genetics, 2014 X-chromosome inactivation (XCI) achieves dosage compensation between males and females through the silencing of the majority of genes on one of the female X chromosomes. Thus, the female X chromosomes provide a unique opportunity to study euchromatin and

FEBS Open Bio, EarlyView.SLC7A11 frequently migrates faster in SDS‐PAGE. The present study found that the high hydrophobicity of SLC7A11 causes its anomalous migration in SDS‐PAGE with a low concentration of acrylamide gel. Replacing isoleucine with asparagine reduced hydrophobicity and restored its normal migration at 55 kDa, revealing the role of hydrophobicity and gel ...

Demasculinization of the
BMC Evolutionary Biology, 2012 Background In a number of organisms sex-biased genes are non-randomly distributed between autosomes and the shared sex chromosome X (or Z). Studies on Anopheles gambiae have produced conflicting results regarding the underrepresentation of male-biased ...
