Targeting CRM1 for Progeria Syndrome Therapy

Aging Cell, EarlyView.
Pharmacological inhibition of CRM1 mediated by selinexor, the first‐in‐class selective inhibitor of CRM1, mitigates the senescent phenotype of Hutchinson‐Gilford progeria syndrome (HGPS) patients‐derived primary fibroblasts. Treatment of HGPS fibroblasts with selinexor promotes the clearances of progerin via autophagy activation, restores the ...

Genetic and Pharmacological Inhibition of Metabotropic Glutamate Receptor Signalling Extends Lifespan in Drosophila

Aging Cell, EarlyView.
We show that genetic and pharmacological inhibition of the metabotropic glutamate receptor, DmGluRA extends Drosophila lifespan, improves stress tolerance and alters early‐life locomotion. Several markers indicative of reduced ribosomal biogenesis, a hallmark of longevity, were also detected in these flies.

Diabetes Advances Cardiomyocyte Senescence Through Interfering Rnd3 Expression and Function

Aging Cell, EarlyView.
Diabetes‐induced upregulation of miR‐103a‐3p suppresses Rnd3 expression in cardiomyocytes, thereby promoting the senescence‐associated secretory phenotype (SASP) through activation of the STAT3 signaling pathway, mediated by UPS‐induced degradation of p‐STAT3.

Age‐Dependent Regulation of Hippocampal Inflammation by the Mitochondrial Translocator Protein in Mice

Aging Cell, EarlyView.
The role of mitochondrial translocator protein (TSPO) in hippocampal inflammation is age‐dependent, with TSPO deletion drastically exacerbating inflammation in aged mice, while dampening it in young mice. This TSPO–aging interaction was linked to NF‐kβ and interferon regulatory transcriptional networks. TSPO deletion exacerbated age‐dependent depletion

Genetic Determinants of the Familial Hypercholesterolaemia Phenotype

Annals of Human Genetics, EarlyView.
ABSTRACT Individuals with familial hypercholesterolaemia (FH) have severely elevated plasma concentrations of low‐density lipoprotein cholesterol (LDL‐C) from birth and as a consequence have an elevated morbidity and mortality due to the development of coronary heart disease (CHD).

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

GTPase-activating proteins and their complexes

Current Opinion in Structural Biology, 1998
In the past year, crystallographic structures for four complexes of GTPase-activating proteins (GAPs) with their target G proteins have been described and substantially enhance our understanding of how these proteins function. GAPs specific for the Rho and Ras families of small G proteins insert an arginine residue into the active site of the G protein,

Rho GTPase-activating proteins in cell regulation [PDF]

Trends in Cell Biology, 2003
Rho family small GTPases serve as molecular switches involved in the regulation of diverse cellular functions including various cytoskeleton-related events and gene transcription. The Rho GTPase-activating proteins (RhoGAPs) are one of the major classes of regulators of Rho GTPases found in all eukaryotes that are crucial in cell cytoskeletal ...

GTPase Activating Proteins

1993
Since Ras proteins negotiate many signalling pathways leading to cell growth or differentiation, the regulation of Ras activity is vital to cellular health. Ras activity, which derives from a collaboration between Ras and GTP, is terminated by the GTPase activating protein (GAP)-catalyzed hydrolysis of the GTP. Hence, a simple regulatory scheme emerges:

Ras interaction with the GTPase‐activating protein (GAP)

Proteins: Structure, Function, and Bioinformatics, 1989
AbstractBiologically active forms of Ras complexed to GTP can bind to the GTP ase‐activating protein (GAP), which has been implicated as a possible target of Ras in mammalian cells. In order to study the structural features of Ras required for this interaction, we have evaluated a series of mutant ras proteins for the ability to bind GAP and a series ...
