Atlas of Plasmodium falciparum intraerythrocytic development using expansion microscopy
Apicomplexan parasites exhibit tremendous diversity in much of their fundamental cell biology, but study of these organisms using light microscopy is often hindered by their small size.

Aurora kinases orchestrate mitosis; who are the players?
The Aurora are a conserved family of serine/threonine kinases with essential functions in cell division. In mitosis, Aurora kinases are required for chromosome segregation, condensation and orientation in the metaphase plate, spindle assembly, and the ...

Cytokinesis requires activation of the GTPase RhoA. ECT-2, the exchange factor responsible for RhoA activation, is regulated to ensure spatiotemporal control of contractile ring assembly.

Curvature-induced expulsion of actomyosin bundles during cytokinetic ring contraction
Many eukaryotes assemble a ring-shaped actomyosin network that contracts to drive cytokinesis. Unlike actomyosin in sarcomeres, which cycles through contraction and relaxation, the cytokinetic ring disassembles during contraction through an unknown ...

An ATM-CHK2-INCENP pathway prevents chromatin breakage by regulating the abscission checkpoint
In response to chromatin bridges, the chromosomal passenger complex (CPC) delays completion of cytokinesis (abscission) to prevent chromosome breakage.

The actomyosin ring generates force to ingress the cytokinetic cleavage furrow in animal cells, yet its filament organization and the mechanism of contractility is not well understood.

A complex role of Arabidopsis CDKD;3 in meiotic progression and cytokinesis
Meiosis is a specialized cell division that halves the number of chromosomes in two consecutive rounds of chromosome segregation. In angiosperm plants is meiosis followed by mitotic divisions to form rudimentary haploid gametophytes.

Regulation of the Total Cell Surface Area in Dividing Dictyostelium Cells
When a cell divides into two daughter cells, the total cell surface area should increase. There are two models for membrane supply to support cell division: (1) unfolding of small surface membrane reservoirs such as microvilli or wrinkles and (2 ...

The human Periodontal Ligament Stem Cells (hPDLSCs) exhibit self-renewal capacity and clonogenicity potential. The Extracellular Vesicles (EVs) secreted by hPDLSCs are particles containing lipids, proteins, mRNAs, and non-coding RNAs, among which ...

Survivin, a member of the inhibitor of apoptosis protein (IAP) family, is detected in most common human cancers but not in adjacent normal cells. Previous studies suggest that survivin associates with the mitotic spindle and directly inhibits caspase ...
