\u3cem\u3eAnolis\u3c/em\u3e Sex Chromosomes Are Derived from A Single Ancestral Pair [PDF]
, 2014 To explain the frequency and distribution of heteromorphic sex chromosomes in the lizard genus Anolis, we compared the relative roles of sex chromosome conservation versus turnover of sex‐determining mechanisms. We used model‐based comparative methods to

Molecular Oncology, EarlyView.B‐cell chronic lymphocytic leukemia (B‐CLL) and monoclonal B‐cell lymphocytosis (MBL) show altered proteomes and phosphoproteomes, analyzed using mass spectrometry, protein microarrays, and western blotting. Identifying 2970 proteins and 316 phosphoproteins, including 55 novel phosphopeptides, we reveal BCR and NF‐kβ/STAT3 signaling in disease ...

PLoS ONE, 2014 Reptiles have a wide diversity of sex-determining mechanisms and types of sex chromosomes. Turtles exhibit temperature-dependent sex determination and genotypic sex determination, with male heterogametic (XX/XY) and female heterogametic (ZZ/ZW) sex ...

Kaelin Rapport - Histological Techniques for the Sex Determination of Skeletonized Human Remains [PDF]
, 2014 Determining the sex of skeletons is problematic in forensic and bio-archaeological research. Past studies demonstrate that bone cells can sometimes contain preserved sex chromosomal material in ancient samples. The sex chromosomes in skeletal remains may

Repeated sex chromosome evolution in vertebrates supported by expanded avian sex chromosomes
Proceedings of the Royal Society B, 2019 Sex chromosomes have evolved from the same autosomes multiple times across vertebrates, suggesting that selection for recombination suppression has acted repeatedly and independently on certain genetic backgrounds.

Molecular Oncology, EarlyView.This study investigates gene expression differences between two major pediatric acute lymphoblastic leukemia (ALL) subtypes, B‐cell precursor ALL, and T‐cell ALL, using a data‐driven approach consisting of biostatistics and machine learning methods. Following analysis of a discovery dataset, we find a set of 14 expression markers differentiating the ...

The multiple sex chromosomes of platypus and echidna are not completely identical and several share homology with the avian Z. [PDF]
, 2007 BACKGROUND: Sex-determining systems have evolved independently in vertebrates. Placental mammals and marsupials have an XY system, birds have a ZW system.

Molecular Oncology, EarlyView.The COMBAT classification system, developed through multi‐omics integration, stratifies adult patients with B‐cell acute lymphoblastic leukemia(B‐ALL) into three molecular subtypes with distinct surface antigen patterns, immune landscape, methylation patterns, biological pathways and prognosis.

Positive selection underlies Faster-Z evolution of gene expression in birds. [PDF]
, 2015 The elevated rate of evolution for genes on sex chromosomes compared to autosomes (Fast-X or Fast-Z evolution) can result either from positive selection in the heterogametic sex, or from non-adaptive consequences of reduced relative effective population ...

Dynamic evolutionary history and gene content of sex chromosomes across diverse songbirds
Nature Ecology & Evolution, 2018 Songbirds have a species number close to that of mammals and are classic models for studying speciation and sexual selection. Sex chromosomes are hotspots of both processes, yet their evolutionary history in songbirds remains unclear.
