Telomerase counteracts telomere erosion that stems from incomplete chromosome end replication and nucleolytic processing. A precise understanding of telomere length homeostasis has been hampered by the lack of assays that delineate the nonuniform telomere ...
Cisplatin is widely used in clinic treatment against a variety of cancer diseases. It binds to two adjacent guanine residues and induces a bend in the DNA double helix. It is believed that cell death is induced upon binding of proteins, which recognize pla ...
This article describes the addition to the von Neumann cellular automaton of the Tom Thumb Algorithm, a mechanism developed for the self-replication of multi-processor systems. Except for the cell construction process, every functionality of the original C ...
BACKGROUND: Acquisition of lineage-specific cell cycle duration is a central feature of metazoan development. The mechanisms by which this is achieved during early embryogenesis are poorly understood. In the nematode Caenorhabditis elegans, differential ce ...
The interaction of a microbial pathogen with its host is a highly dynamic process shaped by evolution. Understanding cellular responses to microbial products is essential for a complete understanding of virulence. Similarly, studies aimed at determining ho ...
Asymmetric divisions are crucial for generating cell diversity; they rely on coupling between polarity cues and spindle positioning, but how this coupling is achieved is poorly understood. In one-cell stage Caenorhabditis elegans embryos, polarity cues set ...
We have generated novel lentiviral vectors to integrate various connexin cDNAs into primary, non-dividing cells. We have used these vectors to test whether proper control of insulin secretion depends on a specific connexin isoform and/or on its level of ex ...
The mechanisms orchestrating spatial cell division control remain poorly understood. In animal cells, the position of the mitotic spindle dictates cleavage furrow placement, and thus plays a key role in governing spatial relationships between resulting dau ...
BACKGROUND: Modulation of microtubule dynamics is crucial for proper cell division. While a large body of work has made important contributions to our understanding of the mechanisms governing microtubule dynamics in vitro, much remains to be learned about ...
Lamellipodia of crawling cells represent both the motor for cell advance and the primary building site for the actin cytoskeleton. The organization of actin in the lamellipodium reflects actin dynamics and is of critical importance for the mechanism of cel ...
