SAK1, a novel cytoplasmic phosphoprotein, is a key intermediate component of the retrograde signaling pathway controlling nuclear gene expression during acclimation of Chlamydomonas cells to singlet oxygen stress.

Bioinformatic analysis of gene expression in chimeric heterokaryons can identify novel regulators of cell lineage.

p27Kip1 directly controls invadopodia turnover by promoting the interaction of PAK1 with Cortactin, which induces Cortactin phosphorylation, invadopodia disassembly and facilitates invasion through extracellular matrix.

Hematopoietic stem and progenitor cells are heterogeneous on a population level, while cells derived from a common ancestor have similar division and differentiation patterns, indicating priming towards a certain differentiation/division fate.

Reduced energy expenditure in obesity may result from reduced sensitivity to sympathetic activation due to inflammation-generated signals in adipose tissue.

Unc-4 acts in a lineage-specific manner to promote different neuronal fates and locomotion behavior in Drosophila.

The identification of the splicing code and all the required components of alternative splicing will be crucial for a comprehensive understanding of this process in the neural crest cell biology.

An innate immune system signaling pathway in planarians has a dual role: it enhances apoptosis during bacterial infection, but represses apoptosis during tissue regeneration in the absence of infection.

PAK1 regulates inhibitory synaptic transmission in mice through a cyclooxygenase-2 dependent restriction in tonic, but not phasic, secretion of endocannabinoids.

Shearing in fluid flow induces or enhances budding dispersal in microbial populations, resulting in stronger cooperative behavior.
