GTP‐binding proteins of the Rho/Rac family: regulation, effectors and functions in vivo [PDF]

open access: yesBioEssays, 2007
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

Dynein‐Dependent Endo‐Lysosomal Degradation Drives Lewy Body Disorders Accompanied by Aβ Pathology

open access: yesAdvanced Science, EarlyView.
This study investigates the impact of Aβ plaques on α‐synuclein (αSyn) pathologies in dementia with Lewy bodies (DLB). Co‐culturing primary neurons with AD mouse brain slices reveals impaired dynein‐dependent organelle trafficking, affecting αSyn degradation. Activating Rab7 restores this process, reducing αSyn inclusions.

Flux Analysis in Process Models via Causality

open access: yes, 2010
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

An Allele of Glutamate Formiminotransferase Triggers 5‐Methyl‐Tetrahydrofolate‐to‐MeFox Conversion and Facilitates Folate Biofortification in Maize

open access: yesAdvanced Science, EarlyView.
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.

Activation of Lysosomal Retrograde Transport Triggers TPC1‐IP3R1 Ca2+ Crosstalk at Lysosome‐ER MCSs Leading to Lethal Depleting of ER Calcium

open access: yesAdvanced Science, EarlyView.
The flavonoid compound LW‐213 exerts its antitumor effects through a novel mechanism involving lysosomal‐ER calcium regulation. Specifically, LW‐213 binds to LIMP2, which induces perinuclear clustering of lysosomes and facilitates calcium‐mediated lysosome‐ER interactions.

Tubulins in C. elegans [PDF]

open access: yes, 2018
The C. elegans tubulin family is composed of nine α-, six β-, and one γ-tubulin. Tubulins are highly conserved, functioning as α-β heterodimers that assemble into microtubules.

The DEC2‐SCN2A Axis is Essential for the Anticonvulsant Effects of Cannabidiol by Modulating Neuronal Plasticity

open access: yesAdvanced Science, EarlyView.
This study identifies DEC2 as a critical transcriptional repressor of Scn2a that directly binds E‐box motifs in its promoter to regulate neuronal plasticity and epileptogenesis. Functional manipulation of DEC2 alters seizure susceptibility in vivo. Cannabidiol enhances this repression, unveiling a novel DEC2‐SCN2A axis underlying its anticonvulsant ...

Control of Striatal Signaling by G Protein Regulators

open access: yesFrontiers in Neuroanatomy, 2011
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 ...

RAB family gene expression in breast cancer cells under influence of paclitaxel [PDF]

open access: yes, 2011
The aim of this study was to investigate the role of paclitaxel on RAB family of genes in primary breast cancer cell lines. The cancer breast cells obtained from 40 women during mastectomy were used to address this issue. The group included patients with

Chlamydia Hijacks ARF GTPases To Coordinate Microtubule Posttranslational Modifications and Golgi Complex Positioning. [PDF]

open access: yes, 2017
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.
