This study investigates a schematic overview of the mechanistic pathways. The relationship between myopia and DR has long been of clinical interest. In diabetic mice, Nna1 expression is downregulated, whereas in diabetic mice with FDM, Nna1 expression is upregulated–particularly in Müller cells–accompanied by decreased vascular endothelial growth ...

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.

Chlamydia Hijacks ARF GTPases To Coordinate Microtubule Posttranslational Modifications and Golgi Complex Positioning. [PDF]
The intracellular bacterium Chlamydia trachomatis develops in a parasitic compartment called the inclusion. Posttranslationally modified microtubules encase the inclusion, controlling the positioning of Golgi complex fragments around the inclusion.

Developmentally Regulated GTP binding protein 1 (DRG1) controls microtubule dynamics [PDF]
AbstractThe mitotic spindle, essential for segregating the sister chromatids into the two evolving daughter cells, is composed of highly dynamic cytoskeletal filaments, the microtubules. The dynamics of microtubules are regulated by numerous microtubule associated proteins.

Mobile messenger RNAs (mRNAs) can travel long distances, serving as systemic signals that participate in plant growth and stress acclimation. This work determines that PHR proteins mediate the Pi starvation response (PSR)‐specific long‐distance transport of mRNAs and that these PSR‐specific mobile mRNAs represent noncoding transcripts in recipient ...

Regulators of G protein signalling proteins in the human myometrium [PDF]
The contractile state of the human myometrium is controlled by extracellular signals that promote relaxation or contraction. Many of these signals function through G proteincoupled receptors at the cell surface, stimulating heterotrimeric G proteins and ...

Proposed model of orally administered onion mitochondria (O‐Mit) uptake by lung macrophages and fuse with macrophage mitochondria (M‐Mit). This fusion reprograms the metabolism of dysfunctional M‐Mit in lipopolysaccharide‐induced murine acute lung injury by modulating dynamin‐related protein 1 (DRP1) phosphorylation and cardiolipin peroxidation ...

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

Molecular mechanism of Gαi activation by non-GPCR proteins with a Gα-Binding and Activating motif [PDF]
Heterotrimeric G proteins are quintessential signalling switches activated by nucleotide exchange on Gα. Although activation is predominantly carried out by G-protein-coupled receptors (GPCRs), non-receptor guanine-nucleotide exchange factors (GEFs) have

Control of Striatal Signaling by G Protein Regulators
Signaling via heterotrimeric G proteins plays a crucial role in modulating the responses of striatal neurons that ultimately shape core behaviors mediated by the basal ganglia circuitry, such as reward valuation, habit formation, and movement ...
