The elemental mechanism of transcriptional pausing. [PDF]

open access: yes, 2019
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.

Regulators of G protein signalling proteins in the human myometrium [PDF]

open access: yes, 2009
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 ...

Low YTHDC1 Expression Upregulates FSCN1 to Promote Nuclear F‐Actin Formation and Facilitate Double‐strand DNA Breaks Repair in TMZ‐Resistant Glioblastoma

open access: yesAdvanced Science, EarlyView.
This study revealed that low expression of YTHDC1 in TMZ‐resistant GBM cells leads to increased FSCN1 expression, which is suppressed by m6A modification. FSCN1 activates the CDC42/N‐WASP/Arp2/3 axis in the cell nucleus by recruiting the guanine nucleotide exchange factor (GEF) family member FGD1, thereby promoting F‐actin polymerization in the nucleus.

The long noncoding RNA CARDINAL attenuates cardiac hypertrophy by modulating protein translation

open access: yesThe Journal of Clinical Investigation
One of the features of pathological cardiac hypertrophy is enhanced translation and protein synthesis. Translational inhibition has been shown to be an effective means of treating cardiac hypertrophy, although system-wide side effects are common ...

New Angle of View on the Role of Rho/Rho Kinase Pathway in Human Diseases

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2014
Rho-kinase is an effector molecule of RhoA, a monomeric GTP-binding protein, and causes Ca2+ sensitization through inactivation of myosin phosphatase.

GAP activity, but not subcellular targeting, is required for Arabidopsis RanGAP cellular and developmental functions [PDF]

open access: yes, 2015
The Ran GTPase activating protein (RanGAP) is important to Ran signaling involved in nucleocytoplasmic transport, spindle organization, and postmitotic nuclear assembly.

Targeted 2‐Deoxy‐D‐Ribose Delivery by Biomimetic Nanoplatform Activates EGFR for Accelerated Heart Valve Endothelialization

open access: yesAdvanced Science, EarlyView.
This study develops a biomimetic nanoplatform using erythrocyte membrane‐camouflaged, CD144 antibody‐functionalized nanoparticles to deliver 2‐deoxy‐D‐ribose (2dDR). This system promotes heart valve endothelialization by enhancing endothelial cell migration and proliferation via EGFR activation, while improving hemocompatibility.

Caveolin-1 Phosphorylation Is Essential for Axonal Growth of Human Neurons Derived From iPSCs. [PDF]

open access: yes, 2019
Proper axonal growth and guidance is essential for neuron differentiation and development. Abnormal neuronal development due to genetic or epigenetic influences can contribute to neurological and mental disorders such as Down syndrome, Rett syndrome, and

Hanks-Type Serine/Threonine Protein Kinases and Phosphatases in Bacteria: Roles in Signaling and Adaptation to Various Environments [PDF]

open access: yes, 2018
Reversible phosphorylation is a key mechanism that regulates many cellular processes in prokaryotes and eukaryotes. In prokaryotes, signal transduction includes two-component signaling systems, which involve a membrane sensor histidine kinase and a ...

Developmentally regulated GTP-binding protein 2 coordinates Rab5 activity and transferrin recycling

open access: yesMolecular Biology of the Cell, 2016
The small GTPase Rab5 regulates the early endocytic pathway of transferrin (Tfn), and Rab5 deactivation is required for Tfn recycling. Rab5 deactivation is achieved by RabGAP5, a GTPase-activating protein, on the endosomes. Here we report that recruitment of RabGAP5 is insufficient to deactivate Rab5 and that developmentally regulated GTP-binding ...
