Little is known about the dynamics of chromosomes in interphase nuclei. By tagging four chromosomal regions with a green fluorescent protein fusion to lac repressor, we monitored the movement and subnuclear position of specific sites in the yeast genome, s ...
The molecular mechanisms regulating cell proliferation and development during the life cycle of malaria parasites remain to be elucidated. The peculiarities of the cell cycle organization during Plasmodium falciparum schizogony suggest that the modalities ...

We have analyzed the subnuclear position of early- and late-firing origins of DNA replication in intact yeast cells using fluorescence in situ hybridization and green fluorescent protein (GFP)-tagged chromosomal domains. In both cases, origin position was ...
Various methods exist to transfect mammalian cells in culture. It is generally accepted that individual methods have to be optimized for each of the cell lines or cell types used. Despitethe use of optimized protocols, significant day-to-day variationsin t ...
The nuclear receptor PPARgamma is implicated in the control of cell proliferation and apoptosis. However, the molecular mechanisms by which it controls these processes remain largely elusive. We show here that PPARgamma activation in the presence of the re ...
Though helium plasmas are one option for the low activation phase of ITER, little effort has thus far been devoted to studying them in a large, diverted tokamak. A recent campaign on JET has therefore sought to address some of the important questions relat ...
A major goal of molecular oncology is to identify means to kill cells lacking p53 function. Most current cancer therapy is based on damaging cellular DNA by irradiation or chemicals. Recent reports support the notion that, in the event of DNA damage, the p ...
The mitotic exit network (MEN) and the septation initiation network (SIN) control events at the end of mitosis in S. cerevisiae and S. pombe, respectively. SIN initiates contraction of the actin ring and synthesis of the division septum, thereby bringing a ...
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 ...
In the TCV tokamak, the m/n = 2/1 island is observed in low-density discharges with central electron-cyclotron current drive. The evolution of its width has two distinct growth phases, one of which can be linked to a "conventional" tearing mode driven unst ...
