The cell biology and genome of <i>Stentor pyriformis</i>, a giant cell that embeds symbiotic algae in a microtubule meshwork Open
Endosymbiotic events in which an endosymbiont is retained within a cell that remains capable of phagocytosis, a situation known as mixotrophy, provide potentially important clues about the eukaryotic evolution. Here we describe the cell bi…

Model-based trajectory classification of anchored molecular motor-biopolymer interactions Open
During zygotic mitosis in many species, forces generated at the cell cortex are required for the separation and migration of paternally provided centrosomes, pronuclear migration, segregation of genetic material, and cell division. Further…

Trajectory Classification Method for Anchored Molecular Motor-Biopolymer Interactions in the C. elegans first Mitosis Open
During zygotic mitosis, forces generated at the cell cortex are required for the separation and migration of paternally provided centrosomes, pronuclear migration, proper segregation of genetic material, and successful cell division. Ident…

Single-particle tracking of dynein identifies PP2A B55/SUR-6 as a cell cycle regulator of cortical force generation Open
Convergence and positioning of the pronuclei and mitotic spindle of many zygotes aids efficient division and is essential for early embryonic patterning. In the C. elegans zygote, interactions between microtubules and cortically anchored d…

Why scientific societies should involve more early-career researchers Open
Early-career researchers (ECRs) make up a large portion of the academic workforce. Yet, most leadership positions in scientific societies are held by senior scientists, and ECRs have little to no say over the decisions that will shape the …

Who’s On Board: Early Career Researchers Hold Scarce, yet Valuable Roles Within Scientific Societies Open
Early career researchers (ECRs) represent a large proportion of the research enterprise, yet they are largely excluded from decision-making opportunities including conference organization, funding administration, and manuscript peer review…

MITOTIC REGULATION OF NUCLEAR ASSEMBLY, POSITIONING AND FUNCTION Open
The eukaryotic nucleus is assembled, disassembled and positioned in a regulated fashion through mitotic progression. During mitotic entry, an interplay between kinases including the cyclin dependent kinase 1 (CDK1) with its binding partner…

Centromeric SMC1 promotes centromere clustering and stabilizes meiotic homolog pairing Open
During meiosis, each chromosome must selectively pair and synapse with its own unique homolog to enable crossover formation and subsequent segregation. How homolog pairing is maintained in early meiosis to ensure synapsis occurs exclusivel…

PP2A-B55/SUR-6 collaborates with the nuclear lamina for centrosome separation during mitotic entry Open
Across most sexually reproducing animals, centrosomes are provided to the oocyte through fertilization and must be positioned properly to establish the zygotic mitotic spindle. How centrosomes are positioned in space and time through the c…

Centrosome-nuclear envelope tethering and microtubule motor-based pulling forces collaborate in centrosome positioning during mitotic entry Open
Centrosome positioning relative to the nucleus and cell shape is highly regulated across cell types, during cell migration and during spindle formation in cell division. Across most sexually reproducing animals, centrosomes are provided to…

Nucleo-cytoplasmic trafficking regulates nuclear surface area during nuclear organogenesis Open
Throughout development, nuclei must be assembled following every cell division to establish a functional organelle from compact, mitotic chromatin. During nuclear organogenesis, chromatin expands to establish a nucleus of a given size sepe…
