Aurora B and Aurora C pools at two chromosomal regions collaboratively maintain chromosome alignment and prevent aneuploidy at the second meiotic division in mammalian oocytes

Frontiers in Cell and Developmental Biology
Correct chromosome segregation is essential to preserve genetic integrity. The two protein kinases, Aurora B and its meiotic homolog Aurora C, regulate attachments between chromosomal kinetochores and microtubules, thereby contributing to the accuracy of

Survival outcomes in dogs treated with vinorelbine‐based adjuvant treatment following surgical resection of grade II and III pulmonary carcinoma

Journal of Small Animal Practice, EarlyView.
Objectives Pulmonary carcinoma in dogs is commonly managed with surgical resection; however, the role of adjuvant chemotherapy for grade II and III carcinomas remains unclear. This retrospective multicentre study investigated the outcomes in dogs treated with vinorelbine‐based adjuvant treatment (as monotherapy or combined chemotherapy) following ...

Scaffold Attachment of DNA Loops in Metaphase Chromosomes

, 1988
We have examined the higher-order loop organization of DNA in interphase nuclei and metaphase chromosomes from Drosophila Kc cells, and we detect no changes in the distribution of scaffold-attached regions (SARs) between these two phases of the cell ...

GhTTLL12 Coordinates With Transcriptional Regulators GhMML3 and GhMYB86 to Orchestrate Cotton Fibre Development Through Modulating Microtubule Dynamics

Plant Biotechnology Journal, EarlyView.
ABSTRACT Microtubules (MTs) are crucial for cell division, growth, development and morphogenesis in plants. Cotton fibres are single‐celled trichomes that originate from the epidermal cells of the ovule, making them an excellent model for studying plant cell differentiation and rapid elongation.

New Considerations on Meiosis, Affinity and Genomic Constitution in Aneuploids and Interploid Hybrids of Urochloa P. Beauv. (Brachiaria)

Plant Breeding, EarlyView.
ABSTRACT The combination of polyploidy, apomixis and the formation of aneuploid and interploid hybrids makes the genus Urochloa an interesting system for investigating meiotic stability and genome behaviour in grasses. In this study, routine meiotic analysis and genomic in situ hybridization (GISH) were used to (i) evaluate meiosis in three hybrids of ...

Modulation of Anaphase‐Promoting Complex Genes Regulates Root‐Knot Nematode Gall Development and Plant Susceptibility

Plant, Cell &Environment, EarlyView.
ABSTRACT The anaphase‐promoting complex/cyclosome (APC/C) is a multi‐subunit E3 ubiquitin ligase that regulates cell cycle progression, but its role in plant‐pathogen interactions is poorly understood. Here, we demonstrate that regulation of the ubiquitin–proteasome system, involving APC/C‐associated components, is critical for coordinating host cell ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, Volume 101, Issue 5, Page 2265-2278, October 2026.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

The Sleeping Giant: Metabolism and Autophagy in the Generation and Survival of Dormant Polyploid Giant Cancer Cells

MedComm, Volume 7, Issue 10, October 2026.
Polyploid giant cancer cells (PGCCs) arise in response to stress and play a critical role in therapy resistance and tumor dormancy. These cells can evade conventional treatments and later contribute to cancer relapse by generating progeny through nonmitotic, amitotic mechanisms.
