The dynamics of replication licensing in live Caenorhabditis elegans embryos [PDF]

open access: yes, 2012
Accurate DNA replication requires proper regulation of replication licensing, which entails loading MCM-2-7 onto replication origins. In this paper, we provide the first comprehensive view of replication licensing in vivo, using video microscopy of ...

Cyclin B3 activates the Anaphase-Promoting Complex/Cyclosome in meiosis and mitosis.

open access: yesPLoS Genetics, 2020
In mitosis and meiosis, chromosome segregation is triggered by the Anaphase-Promoting Complex/Cyclosome (APC/C), a multi-subunit ubiquitin ligase that targets proteins for degradation, leading to the separation of chromatids.

Gibberellin signalling mediates nucleocytoplasmic trafficking of Sucrose Synthase 1 to regulate the drought tolerance in rice

open access: yesPlant Biotechnology Journal, EarlyView.
Summary The Green Revolution (GR) has substantially improved cereal crop yields and enhanced adaptation to diverse environmental challenges. However, the molecular and cellular mechanisms involving GR‐related genes that regulate drought tolerance in plants remain largely unclear.

Splicing factors Sf3A2 and Prp31 have direct roles in mitotic chromosome segregation [PDF]

open access: yes, 2018
Several studies have shown that RNAi-mediated depletion of splicing factors (SFs) results in mitotic abnormalities. However, it is currently unclear whether these abnormalities reflect defective splicing of specific pre-mRNAs or a direct role of the SFs ...

Exploration of histone protein γ‐H2AX as a prognostic factor in soft tissue sarcomas and its association with biological behavior, immune cell environment and survival in leiomyosarcoma

open access: yesInternational Journal of Cancer, Volume 156, Issue 11, Page 2237-2250, 1 June 2025.
What's new? The remarkably poor prognosis of metastasized soft tissue sarcoma (STS) has motivated a search for novel biomarkers and therapeutic approaches. A promising candidate biomarker is H2A histone family member X (H2AX), a key player in DNA damage detection and repair pathways.

Sequestration of CDH1 by MAD2L2 prevents premature APC/C activation prior to anaphase onset

open access: yesJournal of Cell Biology, 2013
MAD2L2 is rapidly degraded by APC/CCDC20 at the onset of anaphase, allowing release of sequestered CDH1 to activate the dephosphorylated APC/C.

Cyto‐Genotoxic Assessment of Sulfoxaflor in Allium cepa Root Cells and DNA Docking Studies

open access: yesMicroscopy Research and Technique, Volume 88, Issue 5, Page 1521-1533, May 2025.
Cyto‐genotoxic Assessment of Sulfoxaflor in Allium cepa Root Cells and DNA Docking Studies. ABSTRACT Sulfoxaflor (SFX) is an insecticide that is commonly used for the control of sap‐feeding insects. Since SFX is extensively applied globally, it has been implicated in the substantial induction of environmental toxicity.

Patronin mediates a switch from kinesin-13–dependent poleward flux to anaphase B spindle elongation

open access: yesJournal of Cell Biology, 2013
Patronin counteracts KLP10A activity at spindle poles to stabilize microtubule minus ends and induce spindle elongation during anaphase B.

Multi‐Omic Evaluation of PLK1 Inhibitor—Onvansertib—In Colorectal Cancer Spheroids

open access: yesJournal of Mass Spectrometry, Volume 60, Issue 5, May 2025.
ABSTRACT Polo‐like kinase 1 (Plk1) is a serine/threonine kinase involved in regulating the cell cycle. It is activated by aurora kinase B along with the cofactors Borealin, INCE, and survivin. Plk1 is involved in the development of resistances to chemotherapeutics such as doxorubicin, Taxol, and gemcitabine.

Meiotic cellular rejuvenation is coupled to nuclear remodeling in budding yeast. [PDF]

open access: yes, 2019
Production of healthy gametes in meiosis relies on the quality control and proper distribution of both nuclear and cytoplasmic contents. Meiotic differentiation naturally eliminates age-induced cellular damage by an unknown mechanism.
