HRD1 prevents apoptosis in renal tubular epithelial cells by mediating eIF-2a ubiquitylation and degradation.
-
ER stress is induced early in EAE and that modulation of ER stress by inhibition of eIF2alpha-CHOP and activation of XBP-1 in RGC specifically, protects RGC somata and axons and preserves visual function.
-
alpha-asarone abrogated 7beta-hydroxycholesterol-triggered eIF2alpha-CHOP activation, and enhanced macrophage beclin1 dependent autophagy.
-
In response to endoplasmic reticulum stress, activation of PERK coordinates the integrated stress response by phosphorylating eIF2alpha, which is then quickly dephosphorylated by the GADD34 complex. Data imply dual role of the ISR in promoting and inhibiting medulloblastoma tumorigenesis.
-
stress granule formation is a downstream event of eIF2alpha phosphorylation that may not directly protect cells from apoptosis, at least in spermatocytes of seminiferous tubules in early stages.
-
results further extended the understanding of Heme-regulated eIF2alpha kinase on the regulation of non-erythroid lineages and might provide new aspects for preventing and treating Cd-induced detrimental effects
-
Data, including data from studies using cells from knockout mice, suggest that gasotransmitter H(2)S up-regulates eIF2a phosphorylation by inhibiting PPP1CA via persulfidation, which in turn leads to transient suppression of global translation and activation of Atf4 expression. (eIF2a = eukaryotic initiation factor-2alpha; PPP1CA = protein phosphatase 1 catalytic subunit alpha; Atf4 = activating transcription factor 4)
-
Results mechanistically link multiple forms of dystonia and put forth a new overall cellular mechanism for dystonia pathogenesis, impairment of eIF2alpha signaling, a pathway known for its roles in cellular stress responses and synaptic plasticity.
-
The eIF2A knock out mice strain is viable and to date displays no apparent phenotype.
-
The role of dietary zinc in the expression of proteins involved in the endoplasmic reticulum stress response is reported.
-
Thus, during addiction, cocaine hijacks translational control by p-eIF2alpha, initiating synaptic potentiation and addiction-related behaviors.
-
in mouse skeletal muscle stem cells, general repression of translation, mediated by the phosphorylation of translation initiation factor eIF2alpha at serine 51 (P-eIF2alpha), is required to maintain the quiescent state
-
Skeletal muscle-specific eukaryotic translation initiation factor 2alpha phosphorylation controls amino acid metabolism and fibroblast growth factor 21-mediated non-cell-autonomous energy metabolism.
-
These experiments connect embryonic stem cell growth factors to eIF2alpha phosphorylation.
-
PGRN is a key regulator of insulin resistance and PGRN may mediate its effects, at least in part, by inducing ER stress via the PERK-eIF2alpha dependent pathway
-
The CARE-LUC mouse model represents an innovative tool to investigate the eIF2alpha-ATF4 axis and to develop drugs targeting this important pathway in the remediation of related pathologies.
-
inhibition of eIF2alpha and FAK signaling may play an important role in cigarette smoking-induced lung EC apoptosis and emphysema
-
eIF2a phosphorylation is required for the normal function of intestinal Paneth cells and mucosal homeostasis.
-
Hypothalamic eIF2alpha phosphorylation could play a critical role in the onset of anorexia associated with certain diseases.
-
The pathogenesis of cardiomyopathy in Frederich ataxia correlates with the early and persistent eIF2alpha phosphorylation.
