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 ...

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.

ATR Kinase Is a Crucial Player Mediating the DNA Damage Response in Trypanosoma brucei
DNA double-strand breaks (DSBs) are among the most deleterious lesions that threaten genome integrity. To address DSBs, eukaryotic cells of model organisms have evolved a complex network of cellular pathways that are able to detect DNA damage, activate a

Identification of calpain cleavage sites in the G1 cyclin-dependent kinase inhibitor p19(INK4d) [PDF]
Calpains are a large family of Ca2+-dependent cysteine proteases that are ubiquitously distributed across most cell types and vertebrate species. Calpains play a role in cell differentiation, apoptosis, cytoskeletal remodeling, signal transduction and ...

Targeting of Fzr/Cdh1 for timely activation of the APC/C at the centrosome during mitotic exit
The activity of the anaphase-promoting complex/cyclosome (APC/C) needs to be regulated in time and space to perform different functions. Here the authors show that Spd2 localizes the APC/C activator Fzr at the centrosomes to promote optimal APC/C ...

Antagonistic effects of mitochondrial matrix and intermembrane space proteases on yeast aging
Background In many organisms, aging is characterized by a loss of mitochondrial homeostasis. Multiple factors such as respiratory metabolism, mitochondrial fusion/fission, or mitophagy have been linked to cell longevity, but the exact impact of each one ...

The role of the cell cycle machinery in resumption of postembryonic development [PDF]
Cell cycle activity is required for plant growth and development, but its involvement in the early events that initiate seedling development remains to be clarified. We performed experiments aimed at understanding when cell cycle progression is activated

Conditional control of fluorescent protein degradation by an auxin-dependent nanobody
Current approaches to conditionally deplete target proteins require site-specific genetic engineering or have poor temporal control. Here the authors overcome these limitations by combining the AID system with nanobodies to reversibly degrade GFP-tagged ...

IRBIT Directs Differentiation of Intestinal Stem Cell Progeny to Maintain Tissue Homeostasis
Summary: The maintenance of the intestinal epithelium is ensured by the controlled proliferation of intestinal stem cells (ISCs) and differentiation of their progeny into various cell types, including enterocytes (ECs) that both mediate nutrient ...
