Flux Analysis in Process Models via Causality
We present an approach for flux analysis in process algebra models of biological systems. We perceive flux as the flow of resources in stochastic simulations. We resort to an established correspondence between event structures, a broadly recognised model

The Small GTP-Binding Protein RhoA Regulates a Delayed Rectifier Potassium Channel [PDF]
Tyrosine kinases activated by G protein-coupled receptors can phosphorylate and thereby suppress the activity of the delayed rectifier potassium channel Kv1.2. Using a yeast two-hybrid screen, we identified the small GTP-binding protein RhoA as a necessary component in this process.

This work demonstrates the distinct roles of the glutamate formiminotransferase (GFT) enzyme in plants. The GFT triggers the conversion of 5‐methyl‐tetrahydrofolate to MeFox in plants, a process distinct from its role as a formiminotransferase in mammals.

MAPping out distribution routes for kinesin couriers [PDF]
In the crowded environment of eukaryotic cells, diffusion is an inefficient distribution mechanism for cellular components. Long-distance active transport is required and is performed by molecular motors including kinesins.

GTP‐binding proteins of the Rho/Rac family: regulation, effectors and functions in vivo [PDF]
AbstractRho/Rac proteins constitute a subgroup of the Ras superfamily of GTP hydrolases. Although originally implicated in the control of cytoskeletal events, it is currently known that these GTPases coordinate diverse cellular functions, including cell polarity, vesicular trafficking, the cell cycle and transcriptomal dynamics. In this review, we will

Integrin α8‐Mediated Pericyte Morphogenesis Controls Blood‐Brain Barrier Integrity
This study highlights that ITGA8 impacts pericyte morphology and function, both crucial for BBB integrity, via RhoA/ROCK signaling, thus influencing TGF‐β1 activation through cytoskeletal tension and ECM interactions. Notably, in post‐ischemic recovery models, ITGA8 deficiency exacerbates vascular dysfunction by impairing pericyte‐mediated BBB ...

The chronic glutamate‐induced excitotoxicity hypothesis has profoundly informed the therapeutic strategies employed in Alzheimer’s disease (AD). This study shows pigment epithelium‐derived factor (PEDF) regulates astrocytic glutamate transporter‐1 (GLT‐1)‐mediated glutamate homeostasis and cognition. Reduced PEDF correlates with lower Mini‐Mental State

The elemental mechanism of transcriptional pausing. [PDF]
Transcriptional pausing underlies regulation of cellular RNA biogenesis. A consensus pause sequence that acts on RNA polymerases (RNAPs) from bacteria to mammals halts RNAP in an elemental paused state from which longer-lived pauses can arise.
