Genes (Basel) 2021 Mar 10;12(3). Epub 2021 Mar 10.

Istituto di Biochimica e Biologia Cellulare-CNR, Via P. Castellino, 111, 80131 Naples, Italy.

DDX11/ChlR1 is a super-family two iron-sulfur cluster containing DNA helicase with roles in DNA replication and sister chromatid cohesion establishment, and general chromosome architecture. Bi-allelic mutations of the DDX11 gene cause a rare hereditary disease, named Warsaw breakage syndrome, characterized by a complex spectrum of clinical manifestations (pre- and post-natal growth defects, microcephaly, intellectual disability, heart anomalies and sister chromatid cohesion loss at cellular level) in accordance with the multifaceted, not yet fully understood, physiological functions of this DNA helicase. In the last few years, a possible role of DDX11 in the onset and progression of many cancers is emerging. Read More

Adherens junctions are involved in polarized contractile ring formation in dividing epithelial cells of Xenopus laevis embryos.

Exp Cell Res 2021 May 2;402(1):112525. Epub 2021 Mar 2.

Univ Rennes, CNRS, IGDR (Institut de Génétique et Développement de Rennes), UMR 6290, 2 Avenue Du Professeur Leon Bernard, 35000, Rennes, France. Electronic address:

Cells dividing in the plane of epithelial tissues proceed by polarized constriction of the actomyosin contractile ring, leading to asymmetric ingression of the plasma mem brane. Asymmetric cytokinesis results in the apical positioning of the actomyosin contractile ring and ultimately of the midbody. Studies have indicated that the contractile ring is associated with adherens junctions, whose role is to maintain epithelial tissue cohesion. Read More

Meiotic CENP-C is a shepherd: bridging the space between the centromere and the kinetochore in time and space.

Essays Biochem 2020 09;64(2):251-261

Waksman Institute and Department of Genetics, Rutgers, The State University of New Jersey, Piscataway, NJ, United States of America.

While many of the proteins involved in the mitotic centromere and kinetochore are conserved in meiosis, they often gain a novel function due to the unique needs of homolog segregation during meiosis I (MI). CENP-C is a critical component of the centromere for kinetochore assembly in mitosis. Recent work, however, has highlighted the unique features of meiotic CENP-C. Read More

Recent advances in understanding the role of Cdk1 in the Spindle Assembly Checkpoint.

F1000Res 2020 28;9. Epub 2020 Jan 28.

CEINGE Biotecnologie Avanzate, Naples, 80145, Italy.

The goal of mitosis is to form two daughter cells each containing one copy of each mother cell chromosome, replicated in the previous S phase. To achieve this, sister chromatids held together back-to-back at their primary constriction, the centromere, have to interact with microtubules of the mitotic spindle so that each chromatid takes connections with microtubules emanating from opposite spindle poles (we will refer to this condition as bipolar attachment). Only once all replicated chromosomes have reached bipolar attachments can sister chromatids lose cohesion with each other, at the onset of anaphase, and move toward opposite spindle poles, being segregated into what will soon become the daughter cell nucleus.

The balance between KIFC3 and EG5 tetrameric kinesins controls the onset of mitotic spindle assembly.

Nat Cell Biol 2019 09 2;21(9):1138-1151. Epub 2019 Sep 2.

Zentrum für Molekulare Biologie, Universität Heidelberg, DKFZ-ZMBH Allianz, Heidelberg, Germany.

One of the first steps in mitotic spindle assembly is the dissolution of the centrosome linker followed by centrosome separation driven by EG5, a tetrameric plus-end-directed member of the kinesin-5 family. However, even in the absence of the centrosome linker, the two centrosomes are kept together by an ill-defined microtubule-dependent mechanism. Here we show that KIFC3, a minus-end-directed kinesin-14, provides microtubule-based centrosome cohesion. Read More

Social intolerance is a consequence, not a cause, of dispersal in spiders.

PLoS Biol 2019 07 2;17(7):e3000319. Epub 2019 Jul 2.

Centre de Recherches sur la Cognition Animale, Centre de Biologie Intégrative, Université de Toulouse, CNRS, UPS, Toulouse, France.

From invertebrates to vertebrates, a wealth of species display transient sociality during their life cycle. Investigating the causes of dispersal in temporary associations is important to better understand population dynamics. It is also essential to identify possible mechanisms involved in the evolutionary transition from transient to stable sociality, which has been documented repeatedly across taxa and typically requires the suppression of dispersal.

SET binding to Sgo1 inhibits Sgo1-cohesin interactions and promotes chromosome segregation.

J Cell Biol 2019 08 21;218(8):2514-2528. Epub 2019 Jun 21.

Department of Biochemistry and Molecular Biology and Tulane Aging Center, Tulane University Health Science Center, New Orleans, LA

At anaphase onset, Sgo1 function of cohesion protection must be disabled to allow timely chromosome segregation, but how this is achieved is not fully understood. Here, we show that SET, a known PP2A inhibitor, directly binds to a domain in Sgo1 in close proximity to the cohesin-binding motif. The Sgo1-cohesin binding can be disrupted by SET in a dose-dependent manner in vitro as well as by SET overexpression in cells, suggesting that SET is also an inhibitor to the Sgo1-cohesin binding.

SWITCH 1/DYAD is a WINGS APART-LIKE antagonist that maintains sister chromatid cohesion in meiosis.

Nat Commun 2019 04 15;10(1):1755. Epub 2019 Apr 15.

Department of Developmental Biology, University of Hamburg, Hamburg, 22609, Germany.

Mitosis and meiosis both rely on cohesin, which embraces the sister chromatids and plays a crucial role for the faithful distribution of chromosomes to daughter cells. Prior to the cleavage by Separase at anaphase onset, cohesin is largely removed from chromosomes by the non-proteolytic action of WINGS APART-LIKE (WAPL), a mechanism referred to as the prophase pathway. To prevent the premature loss of sister chromatid cohesion, WAPL is inhibited in early mitosis by Sororin. Read More

Prospective study of polygenic risk, protective factors, and incident depression following combat deployment in US Army soldiers.

Psychol Med 2020 04 15;50(5):737-745. Epub 2019 Apr 15.

Department of Psychiatry, Massachusetts General Hospital, Boston, MA, USA.

Background: Whereas genetic susceptibility increases the risk for major depressive disorder (MDD), non-genetic protective factors may mitigate this risk. In a large-scale prospective study of US Army soldiers, we examined whether trait resilience and/or unit cohesion could protect against the onset of MDD following combat deployment, even in soldiers at high polygenic risk.

Methods: Data were analyzed from 3079 soldiers of European ancestry assessed before and after their deployment to Afghanistan. Read More
