DNA damage triggers squamous metaplasia in human lung and mammary cells via mitotic checkpoints
Epithelial transdifferentiation is frequent in tissue hyperplasia and contributes to disease in various degrees. Squamous metaplasia (SQM) precedes epidermoid lung cancer, an aggressive and frequent malignancy, but it is rare in the epithelium of the ...

Cervical cancer (CC) is the 4th most leading cause of death among women worldwide, and if diagnosed in late stages the treatment options are almost negligible. 99% of CC is caused by high-risk human papilloma viruses (HR-HPV). Upon integration into human

Phasing in on the cell cycle [PDF]
Just like all matter, proteins can also switch between gas, liquid and solid phases. Protein phase transition has claimed the spotlight in recent years as a novel way of how cells compartmentalize and regulate biochemical reactions. Moreover, this discovery has provided a new framework for the study of membrane-less organelle biogenesis and protein ...

The Cell Cycle is a Limit Cycle [PDF]
Progression along the successive phases of the mammalian cell cycle is driven by a network of cyclin-dependent kinases (Cdks). This network is regulated by a variety of negative and positive feedback loops. We previously proposed a detailed, 39-variable model for the Cdk network and showed that it is capable of temporal self-organization in the form of

I review recent advances in our knowledge of the eucaryotic cell cycle: the set of processes by which cells grow and divide. Genetic approaches to the cell cycle of somatic cells identified a pathway of events where the initiation of each event was dependent on the successful completion of the preceding event, as well as a single key gene, cdc2 , that ...

We sought to create a comprehensive catalog of yeast genes whose transcript levels vary periodically within the cell cycle. To this end, we used DNA microarrays and samples from yeast cultures synchronized by three independent methods: alpha factor ...

miR-34a negatively regulates cell cycle factor Cdt2/DTL in HPV infected cervical cancer cells
MicroRNAs have emerged as an important regulator of cell cycle and various other cellular processes. Aberration in microRNAs has been linked with development of several cancers and other diseases but still very little is known about the mechanism by ...

Cell cycle length, cell size, and proliferation rate in hydra stem cells [PDF]
We have analyzed the cell cycle parameters of interstitial cells in Hydra oligactis. Three subpopulations of cells with short, medium, and long cell cycles were identified. Short-cycle cells are stem cells; medium-cycle cells are precursors to nematocyte

Cortical Cyclin A controls spindle orientation during asymmetric cell divisions in Drosophila
The Frizzled/Dishevelled planar cell polarity pathway is involved in mitotic spindle orientation, but how this is coordinated with the cell cycle is unclear.

A neural progenitor mitotic wave is required for asynchronous axon outgrowth and morphology
Spatiotemporal mechanisms generating neural diversity are fundamental for understanding neural processes. Here, we investigated how neural diversity arises from neurons coming from identical progenitors.
