Summary: In this study, live-cell markers are used to track the dynamic reorganization of microtubules, nuclei, endoplasmic reticulum, and endomembrane compartments during division and the formation of the cell plate in maize leaf epidermal cells. The results show that microtubule dynamicity increases during mitosis, supporting rapid changes in microtubule structures. Additionally, the localization of cell-plate specific proteins was assessed after treatment with specific inhibitors.

Summary: Meiosis is a specialized cell division process for gamete production in eukaryotes, with chromosomes and microtubules mutually influencing each other. Studies on the fission yeast Schizosaccharomyces pombe have revealed the organization of chromosomes, cytoskeleton, and cell cycle progression in mitosis and meiosis. Meiosis is strategically designed for faithful genetic material segregation and genetic diversity production through meiosis-specific and general factors.

Summary: Flowering plants contain multiple cyclin families, with B1-type cyclins playing a crucial role in cell cycle control during Arabidopsis development. Mutant analysis revealed complex overlapping requirements of B1-type cyclins, with CYCB1;2 being central. The double mutant cycb1;1 cycb1;2, although compromised in growth, provides a unique opportunity to study the function of B1-type cyclins at the organismic level.

Summary: The spindle is a dynamic intracellular structure essential for chromosome segregation during cell division. It can exhibit varied shape morphologies through nonrandom, bistable self-organization paths. The emergence of different spindle shapes is influenced by both physical and molecular factors.

Summary: Aneuploidy is common in tumors and plays a crucial role in their initiation and evolution. This study reveals that constitutive signaling by RAS or MAPK is necessary for cancer-specific vulnerability to BubR1, a factor involved in preventing aneuploidy. The findings enhance our understanding of how chromosome segregation adapts to different cellular states and identify an oncogenic trigger for a cancer-specific defect.

Summary: Recent studies have shown that Haspin, a protein kinase essential for mitosis, plays a crucial role in the interphase progression of cancer cells. Loss of Haspin results in cell cycle defects, prolonging S/G2 phase, leading to mitotic cell death or postmitotic G1 arrest. Additionally, Haspin deficiency induces p21 checkpoint protein expression and co-depletion with p21 or p53 can partially restore cell proliferation.

Summary: During mitosis, the microtubule crosslinker protein PRC1 recruits motor proteins CENP-E and Kif4A to the central spindle to coordinate chromosome segregation and cytokinesis. This recruitment is mediated by a conserved hydrophobic motif and is spatially and temporally regulated by CENP-E. The interaction between PRC1 and microtubule motor proteins is essential for controlling chromosome partitioning, maintaining central spindle integrity, and ensuring cytokinesis during anaphase.

Summary: The study shows that targeting PRC1 or PLK1 can induce fatal genomic instability and tumor regression in EwS model. EWSR1-FLI1, an oncogenic transcription factor specific to EwS, hijacks PRC1 to promote tumor growth by binding to GGAA microsatellite. High PRC1 expression creates a therapeutic vulnerability towards PLK1 inhibition, leading to repression of even chemo-resistant EwS cells by triggering mitotic catastrophe.

Summary: Aneuploidy plays an important role in cancer, affecting the proteome and leading to expression changes not only in aneuploid chromosomes but also in non-aneuploid ones. Proteins from aneuploid chromosomes tend to co-enrich with each other, and the complexes of the cellular core machinery are under functional selection to maintain stoichiometric balance. The success of a tumor in dealing with aneuploidy-induced stoichiometric imbalance impacts cellular protein degradation programs and patient survival.

Summary: Ran is a member of the Ras superfamily of proteins, regulating nucleocytoplasmic trafficking and mitosis by regulating spindle formation and nuclear envelope reassembly. Aberrant Ran expression in cancer is due to upstream dysregulation and abnormal activation of signaling pathways. Overexpression of Ran affects cell phenotype and has been found in various cancers, correlating with tumor grade and metastasis. Increased dependence on Ran for spindle formation and mitosis, as well as dysregulation of nucleocytoplasmic transport, contribute to the increased malignancy and invasiveness associated with Ran overexpression.

Summary: Eukaryotic cells tightly regulate their size, but the mechanisms underlying size control are not well understood. Fission yeast cells divide at a threshold surface area, which is influenced by the protein kinase Cdr2. However, mutants that divide at a larger size switch to volume-based divisions. Diploid cells divide at a larger size than haploid cells, but still maintain surface area-based divisions, indicating that the size threshold for transitioning from surface-area-based to volume-based control is determined by ploidy. The mitotic activator Cdc25 accumulates as a volume-based sizer molecule, while the mitotic cyclin Cdc13 acts as a timer in the nucleus. A proposed integrated model for cell size control incorporates multiple signaling pathways that report on different aspects of cell size and growth, including surface area (Cdr2), volume (Cdc25), and time (Cdc13). Computational modeling and experimental findings demonstrate how this system can exhibit both size-based regulation and size-addition properties.

Summary: The centrosome of Dictyostelium amoebae consists of a cylindrical layered core structure without centrioles, surrounded by a corona harboring microtubule-nucleating gamma-tubulin complexes. Proteomics, protein interaction studies, and superresolution microscopy methods have significantly advanced our understanding of the composition, structure, and function of this centrosome type. Comparisons of the components of the Dictyostelium centrosome with those of animals and yeasts have been discussed.

Summary: Studies have found that stem cells can self-assemble in the culture dish to mimic early embryonic development. These stem cell-derived models can imitate cell movements and gene expression patterns of gastrulation, and even develop into different organs and tissues. This article explores the journey of discovering and understanding these stem cell capabilities.

Summary: In this study, a 24-amino-acid sequence from the tail anchor domain of the Drosophila proapoptotic protein Hid was used to target exogenous proteins to the mitochondria in Drosophila cells. It was found that Drosophila Sas6 can bind both Drosophila Gorab and its human GORAB ortholog, whereas human SAS6 is unable to bind either GORAB or Gorab. These findings are discussed in relation to the evolutionary conservation of Gorab and the divergence of Sas6.

Summary: Parthenogenesis is widely observed in animals, but remains understudied. In dipterans, it is of particular importance due to the presence of parthenogenetic species that are disease vectors and agricultural pests. This study presents a catalog of parthenogenetic dipterans, explores the genetic basis of parthenogenesis, and discusses the evolutionary significance of parthenogenesis in this order.
