Contrasting roles of condensin I and condensin II in mitotic chromosome formation [PDF]

, 2012
© 2012. Published by The Company of Biologists LtdIn vertebrates, two condensin complexes exist, condensin I and condensin II, which have differing but unresolved roles in organizing mitotic chromosomes.

Chromosomal macrodomains and associated proteins : implications for DNA organization and replication in gram negative bacteria [PDF]

, 2011
The Escherichia coli chromosome is organized into four macrodomains, the function and organisation of which are poorly understood. In this review we focus on the MatP, SeqA, and SlmA proteins that have recently been identified as the first examples of ...

Chromosome segregation analysis in human embryos obtained from couples involving male carriers of reciprocal or Robertsonian translocation. [PDF]

PLoS ONE, 2012
The objective of this study was to investigate the frequency and type of chromosome segregation patterns in cleavage stage embryos obtained from male carriers of Robertsonian (ROB) and reciprocal (REC) translocations undergoing preimplantation genetic ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

A simple biophysical model emulates budding yeast chromosome condensation

eLife, 2015
Mitotic chromosomes were one of the first cell biological structures to be described, yet their molecular architecture remains poorly understood. We have devised a simple biophysical model of a 300 kb-long nucleosome chain, the size of a budding yeast ...

Both Chromosome Decondensation and Condensation Are Dependent on DNA Replication in C.elegans Embryos [PDF]

, 2015
During cell division, chromatin alternates between a condensed state to facilitate chromosome segregation and a decondensed form when DNA replicates.

Spatial and single‐nuclei transcriptomics reveals idiosyncratic and generic patterns in papillary and anaplastic thyroid cancers

Molecular Oncology, EarlyView.
Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Kif11-haploinsufficient oocytes reveal spatially differential requirements for chromosome biorientation

EMBO Reports
Bipolar spindle assembly and chromosome biorientation are prerequisites for chromosome segregation during cell division. The kinesin motor KIF11 (also widely known as Eg5) drives spindle bipolarization by sliding antiparallel microtubules bidirectionally,

Protocol for studying topological DNA interactions by purified fission yeast condensin

STAR Protocols
Summary: To understand the transition from interphase chromatin into well-shaped chromosomes during cell divisions, we need to understand the biochemical activities of the contributing proteins.

Segregation but Not Replication of the Pseudomonas aeruginosa Chromosome Terminates at Dif

mBio, 2018
Coordination between chromosome replication and segregation is essential for equal partitioning of genetic material between daughter cells. In bacteria, this is achieved through the proximity of the origin of replication, oriC, and the chromosome ...
