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.

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 ...

Cell cycle and apoptosis [PDF]
Abstract. Apoptosis and proliferation are intimately coupled. Some cell cycle regulators can influence both cell division and programmed cell death. The linkage of cell cycle and apoptosis has been recognized for c‐Myc, p53, pRb, Ras, PKA, PKC, Bcl‐2, NF‐κB, CDK, cyclins and CKI. This review summarizes the different functions of the proteins presently

The role of CDC25C in cell cycle regulation and clinical cancer therapy: a systematic review
One of the most prominent features of tumor cells is uncontrolled cell proliferation caused by an abnormal cell cycle, and the abnormal expression of cell cycle-related proteins gives tumor cells their invasive, metastatic, drug-resistance, and anti ...

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

Neurogenesis and the Cell Cycle [PDF]
For a long time, it has been understood that neurogenesis is linked to proliferation and thus to the cell cycle. Recently, the gears that mediate this linkage have become accessible to molecular investigation. This review describes some of the progress that has been made in understanding how the molecular machinery of the cell cycle is used in the ...

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

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 ...

Tracking of Normal and Malignant Progenitor Cell Cycle Transit in a Defined Niche. [PDF]
While implicated in therapeutic resistance, malignant progenitor cell cycle kinetics have been difficult to quantify in real-time. We developed an efficient lentiviral bicistronic fluorescent, ubiquitination-based cell cycle indicator reporter (Fucci2BL)
