Spo13 prevents premature cohesin cleavage during meiosis [version 2; peer review: 2 approved, 1 approved with reservations] [PDF]

open access: yesWellcome Open Research, 2019
Background: Meiosis produces gametes through two successive nuclear divisions, meiosis I and meiosis II. In contrast to mitosis and meiosis II, where sister chromatids are segregated, during meiosis I, homologous chromosomes are segregated. This requires

Regulation of cohesin cleavage during meiosis in Saccharomyces cerevisiae [PDF]

open access: yes, 2017
Meiosis is a specialized form of cell division where homologous chromosomes are segregated in meiosis I before sister chromatids are segregated in meiosis II.

Relationships of Telomere Homeostasis with Oxidative Stress and Cardiac Dysfunction in Human Ischaemic Hearts

open access: yesAntioxidants, 2021
Although the roles of telomeres and oxidative stress in ischaemic cardiomyopathy (ICM) are known, mechanisms of telomere homeostasis and their relationship with oxidative stress are incompletely understood. We performed two RNA-seq analyses (mRNA n = 23;

Cohesin mutations alter DNA damage repair and chromatin structure and create therapeutic vulnerabilities in MDS/AML [PDF]

open access: yes, 2021
The cohesin complex plays an essential role in chromosome maintenance and transcriptional regulation. Recurrent somatic mutations in the cohesin complex are frequent genetic drivers in cancer including myelodysplatic syndromes (MDS) and acute myeloid ...

The cohesin ring concatenates sister DNA molecules [PDF]

open access: yes, 2008
Sister chromatid cohesion, which is essential for mitosis, is mediated by a multi-subunit protein complex called cohesin whose Scc1, Smc1, and Smc3 subunits form a tripartite ring structure.

The Caenorhabditis elegans Shugoshin regulates TAC-1 in cilia

open access: yesScientific Reports, 2023
The conserved Shugoshin (SGO) protein family is essential for mediating proper chromosome segregation from yeast to humans but has also been implicated in diverse roles outside of the nucleus.

Smc5/6 coordinates formation and resolution of joint molecules with chromosome morphology to ensure meiotic divisions [PDF]

open access: yes, 2013
During meiosis, Structural Maintenance of Chromosome (SMC) complexes underpin two fundamental features of meiosis: homologous recombination and chromosome segregation.

The chromosomal association of the Smc5/6 complex depends on cohesion and predicts the level of sister chromatid entanglement.

open access: yesPLoS Genetics, 2014
The cohesin complex, which is essential for sister chromatid cohesion and chromosome segregation, also inhibits resolution of sister chromatid intertwinings (SCIs) by the topoisomerase Top2. The cohesin-related Smc5/6 complex (Smc5/6) instead accumulates
