Rapid generation of chromosome-specific alphoid DNA probes using the polymerase chain reaction [PDF]

open access: yes, 1992
Non-isotopic in situ hybridization of chromosome-specific alphoid DNA probes has become a potent tool in the study of numerical aberrations of specific human chromosomes at all stages of the cell cycle. In this paper, we describe approaches for the rapid

Structure of the cohesin loader Scc2

open access: yesNature Communications, 2017
The cohesin complex maintains genome integrity by ensuring correct sister-chromatid segregation during mitosis and meiosis. Here, Chaoet al. present a pseudo-atomic model of the full-length Scc2–Scc4 cohesin loader complex and reveal key Scc2 surfaces ...

Rad53 checkpoint kinase regulation of DNA replication fork rate via Mrc1 phosphorylation

open access: yeseLife, 2021
The Rad53 DNA checkpoint protein kinase plays multiple roles in the budding yeast cell response to DNA replication stress. Key amongst these is its enigmatic role in safeguarding DNA replication forks.

Cell-Cycle Regulation of Dynamic Chromosome Association of the Condensin Complex

open access: yesCell Reports, 2018
Summary: Eukaryotic cells inherit their genomes in the form of chromosomes, which are formed from the compaction of interphase chromatin by the condensin complex. Condensin is a member of the structural maintenance of chromosomes (SMC) family of ATPases,

Induction of chromosome shattering by ultraviolet light and caffeine [PDF]

open access: yes, 1981
Synchronized and asynchronously growing cells of a V79 sub-line of the Chinese hamster were either partial-cell irradiation (λ, 254 nm) or laser-UV-microirradiated (λ, 257 nm).

Y chromosome functions in mammalian spermatogenesis

open access: yeseLife, 2021
The mammalian Y chromosome is critical for male sex determination and spermatogenesis. However, linking each Y gene to specific aspects of male reproduction has been challenging.

Early events in the evolution of the Silene latifolia Y chromosome: Male specialization and recombination arrest [PDF]

open access: yes, 2007
Understanding the origin and evolution of sex chromosomes requires studying recently evolved X-Y chromosome systems such as those in some flowering plants.

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Human RAD51 paralogue SWSAP1 fosters RAD51 filament by regulating the anti-recombinase FIGNL1 AAA+ ATPase

open access: yesNature Communications, 2019
RAD51 assembly on single-stranded DNAs is an important step in the homology-dependent repair of DNA damage. Here authors reveal a role for the human RAD51 paralogue, SWSAP1, as a regulator of RAD51 assembly, by antagonizing RAD51 remodeller, FIGNL1 AAA +

Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

open access: yesFEBS Letters, EarlyView.
This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
