eIF2α phosphorylation is required to prevent hepatocyte death and liver fibrosis in mice challenged with a high fructose diet

Nutrition & Metabolism, 2017
Background Dietary fructose can rapidly cause fatty liver in animals through de novo lipogenesis (DNL) and contribute to the development and severity of nonalcoholic fatty liver disease (NAFLD).

Translation of viral mRNA without active eIF2: the case of picornaviruses. [PDF]

PLoS ONE, 2011
Previous work by several laboratories has established that translation of picornavirus RNA requires active eIF2α for translation in cell free systems or after transfection in culture cells.

Placental growth factor inhibition modulates the interplay between hypoxia and unfolded protein response in hepatocellular carcinoma [PDF]

, 2016
Background: Hepatocellular carcinoma (HCC) is a leading cause of cancer-related mortality. We previously showed that the inhibition of placental growth factor (PlGF) exerts antitumour effects and induces vessel normalisation, possibly reducing hypoxia ...

Astrocytic TIA1‐Mediated Stress Granules Promote the Demyelination of Optic Neuritis by Sequestering mRNA of Cholesterol Synthesis Genes in an Experimental Autoimmune Encephalomyelitis Model

Advanced Science, EarlyView.
Astrocytic TIA1‐mediated stress granules (SGs) promote demyelination by sequestering the mRNA of cholesterol synthesis genes. In this model, astrocytic TIA1‐mediated SGs were increased in the optic nerves of EAE mice, leading to the downregulation of cholesterol synthesis genes such as HMGCS1 through sequestration of their mRNA into SGs, which ...

A Critical Role of the mTOR/eIF2α Pathway in Hypoxia-Induced Pulmonary Hypertension. [PDF]

PLoS ONE, 2015
Enhanced proliferation of pulmonary arterial vascular smooth muscle cells (PASMCs) is a key pathological component of vascular remodeling in hypoxia-induced pulmonary hypertension (HPH). Mammalian targeting of rapamycin (mTOR) signaling has been shown to

Hepatotoxicity of Nonesterified Fatty Acids to Dairy Cows: Pathophysiological Mechanisms and Prospective Solutions

Animal Research and One Health, EarlyView.
Unregulated inflammation increases non‐esterified fatty acids (NEFAs), and triggers multi‐pathway hepatocyte damage including oxidative stress, mitochondrial dysfunction, and metabolic disorders in dairy cows. ABSTRACT Circulating concentrations of nonesterified fatty acids (NEFAs) are elevated due to lipid mobilization from adipose tissue in ...

Interferon alpha suppresses alphaherpesvirus immediate early protein levels in sensory neurons, leading to the establishment of a latent infection [PDF]

, 2010
Alphaherpesviruses are a subfamily of the herpesviruses containing closely related human and animal pathogens, including human herpes simplex virus (HSV-1) and porcine pseudorabies virus (PRV)

Efficacy and immunogenic effects of Tumor Treating Fields (TTFields) in preclinical models of pancreatic ductal adenocarcinoma, with and without gemcitabine/nab‐paclitaxel

International Journal of Cancer, EarlyView.
What's New? Adaptive immune responses are typically limited in pancreatic ductal adenocarcinoma, resulting in minimal efficacy of immune checkpoint inhibitors. Tumor Treating Fields (TTFields) therapy, which uses low‐intensity intermediate‐frequency electric fields to disrupt cancer cell processes, has been approved for certain cancers.

Enhancement of osteoblastogenesis and suppression of osteoclastogenesis by inhibition of de-phosphorylation of eukaryotic translation initiation factor 2 alpha [PDF]

, 2015
The phosphorylation of eukaryotic translation initiation factor 2 alpha (eIF2α) is activated in response to various stresses such as viral infection, nutrient deprivation, and stress to the endoplasmic reticulum.

Non‐invasive and efficient diabetic retinal mitochondrial repair nanoplatform based on engineered endothelial mitochondrial‐derived vesicles with dynamic integrated stress response modulation

Interdisciplinary Medicine, EarlyView.
Under hyperglycemic conditions, mitochondrial dysfunction in retinal endothelial cells triggers excessive reactive oxygen species/reactive nitrogen species production, barrier protein degradation, and endothelial barrier breakdown in diabetic retinopathy.
