Comparative Satellitomics in Arowanas (Telostei, Osteoglossiformes) Sheds Light on the Evolution of Ancient Satellite DNAs

open access: yesIntegrative Zoology, EarlyView.
This work focused on arowana fishes (Teleostei, Osteoglossiformes) as a model; their widespread intercontinental distribution and basal phylogenetic position within Teleostei make them a compelling model for evolutionary research, especially in the realm of satDNA molecular evolution. Through the integration of genomic and chromosomal data, we analyzed

Centromere-size reduction and chromatin state dynamics following intergenomic hybridization in cotton.

open access: yesPLoS Genetics
Centromeres are pivotal for accurate chromosome segregation, yet their regulation and evolutionary dynamics remain poorly understood. Here, we investigate centromeres of the diploid species Gossypium anomalum (Ga, B-genome) that were transferred into ...

Determining the role of centromeric long non-coding RNA in chromosome segregation in saccharomyces cerevisiae

open access: yes, 2016
Centromeric DNA sequences are not conserved among organisms and centromeres are proposed to be regulated epigenetically. Centromeric transcription is one of the epigenetic factors identified in many eukaryotes, and increasing evidences indicate that ...

Centromere emergence in evolution

open access: yes, 2001
Evolutionary centromere repositioning is a paradox we have recently discovered while studying the conservation of the phylogenetic chromosome IX in primates.

The use of deidentified organ donor testes for research

open access: yesAndrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Sperm Telomere Interactions Are Impaired in Testicular Cancer Before and After Adjuvant Therapy

open access: yesAndrology, EarlyView.
ABSTRACT Background No study has yet explored telomere length or interaction in sperm nuclei of testicular cancer (TC) patients exposed to chemotherapy or radiotherapy. However, sperm telomere dynamics have emerged as a potential marker in male infertility.

Centromere proteins CENP-C and CAL1 functionally interact in meiosis for centromere clustering, pairing, and chromosome segregation

open access: yes, 2013
Meiotic chromosome segregation involves pairing and segregation of homologous chromosomes in the first division and segregation of sister chromatids in the second division.

Mesenchymal Stem Cells From a Klinefelter Syndrome Patient: Functional Characterization and Therapeutic Implications

open access: yesAndrology, EarlyView.
ABSTRACT Background Cell therapy, particularly those utilizing mesenchymal stem/stromal cells (MSCs), is gaining traction as a therapeutic option for regenerative treatment in patients with limited therapeutic options. Although the safety of MSC‐based interventions is well established, uncertainties remain regarding how genetic abnormalities and ...

FBXO47 regulates centromere pairing as key component of centromeric SCF E3 ligase in mouse spermatocytes

open access: yesCommunications Biology
Centromere pairing is crucial for synapsis in meiosis. This study delves into the Skp1-Cullin1-F-box protein (SCF) E3 ubiquitin ligase complex, specifically focusing on F-box protein 47 (FBXO47), in mouse meiosis.
