Calcium-mediated calreticulin IRE1α interaction drives dynamic fluctuation of IRE1α activity under chronic endoplasmic reticulum stress

ABSTRACT: To investigate the mechanisms underlying fluctuating IRE1α phosphorylation under chronic endoplasmic reticulum stress, we performed co-immunoprecipitation coupled with mass spectrometry (IP-MS) to identify IRE1α-interacting proteins. Protein complexes were analyzed by LC-MS/MS, followed by bioinformatic enrichment analysis to identify candidate regulators of IRE1α phosphorylation and activity.

Tmem45b Modulates itch via Endoplasmic Reticulum Calcium Regulation

Project description:Chronic itch is detected by dorsal root ganglia (DRG) that severely impairs quality of life. However, its underlying mechanisms remain poorly understood. We identified that Tmem45b was contained in natriuretic peptide type B (Nppb)-, mas-related G-protein coupled receptor member A3 (Mrgpra3)-, and Mrgprd-positive DRG neurons, which are associated with itch sensation. The role of Tmem45b in itch sensation has not been explored. Tmem45b conditional knockout (cKO) mice exhibited decreased scratching to β-alanine, and increased scratching to chloroquine. Notably, Tmem45b cKO alleviated chronic itch. Furthermore, Tmem45b cKO impaired the calcium response to β-alanine and allyl isothiocyanate but not to chloroquine in dissociated DRG neurons. Tmem45b deficiency led to significant downregulation of sarco/endoplasmic reticulum calcium transport ATPase 1 (Serca1), impairing calcium storage capacity of endoplasmic reticulum (ER). Inhibition of Serca1 in DRG neurons reduced intracellular calcium release triggered by β-alanine and chloroquine. Together,Tmem45b deficiency may reduce nonhistaminergic itch and disrupt ER calcium regulation, highlighting a potential target for chronic itch therapy.

Phosphorylation-Regulated Cleavage of ETHYLENE INSENSITIVE2 Mediates Hormone Signaling from the Endoplasmic Reticulum to the Nucleus

Project description:Ethylene gas is essential for many developmental processes and stress responses in plants. ETHYLENE INSENSITIVE2 (EIN2), an NRAMP-homologous integral membrane protein, plays an essential role in ethylene signaling but its function remains enigmatic. Here we report that phosphorylation-regulated proteolytic processing of EIN2 triggers its endoplasmic reticulum (ER)-nucleus translocation, which is essential for hormone signaling and response in Arabidopsis. Without ethylene, or in hormone receptors mutants, ER-tethered EIN2 shows CTR1 kinase-dependent phosphorylation. Ethylene exposure triggers dephosphorylation and proteolytic cleavage, resulting in rapid nuclear translocation of a carboxyl-terminal EIN2 fragment (C’). Plants containing mutations that mimic EIN2 dephosphorylation, or inactivate CTR1, show constitutive cleavage and nuclear localization of EIN2-C’, and EIN3/EIL1-dependent activation of ethylene responses. These findings uncover a mechanism of subcellular communication whereby ethylene gas stimulates rapid phosphorylation-dependent cleavage and nuclear movement of the EIN2-C’ peptide, thus linking hormone perception and signaling components located in the ER with nuclear-localized transcriptional regulators.

Rotavirus Calcium Dysregulation Manifests as Dynamic Calcium Signaling in the Cytoplasm and Endoplasmic Reticulum.

Project description:Like many viruses, rotavirus (RV) dysregulates calcium homeostasis by elevating cytosolic calcium ([Ca2+]cyt) and decreasing endoplasmic reticulum (ER) stores. While an overall, monophasic increase in [Ca2+]cyt during RV infection has been shown, the nature of the RV-induced aberrant calcium signals and how they manifest over time at the single-cell level have not been characterized. Thus, we generated cell lines and human intestinal enteroids (HIEs) stably expressing cytosolic and/or ER-targeted genetically-encoded calcium indicators to characterize calcium signaling throughout RV infection by time-lapse imaging. We found that RV induces highly dynamic [Ca2+]cyt signaling that manifest as hundreds of discrete [Ca2+]cyt spikes, which increase during peak infection. Knockdown of nonstructural protein 4 (NSP4) attenuates the [Ca2+]cyt spikes, consistent with its role in dysregulating calcium homeostasis. RV-induced [Ca2+]cyt spikes were primarily from ER calcium release and were attenuated by inhibiting the store-operated calcium entry (SOCE) channel Orai1. RV-infected HIEs also exhibited prominent [Ca2+]cyt spikes that were attenuated by inhibiting SOCE, underlining the relevance of these [Ca2+]cyt spikes to gastrointestinal physiology and role of SOCE in RV pathophysiology. Thus, our discovery that RV increases [Ca2+]cyt by dynamic calcium signaling, establishes a new, paradigm-shifting understanding of the spatial and temporal complexity of virus-induced calcium signaling.

Polysome profiling in liver identifies dynamic regulation of endoplasmic reticulum translatome by obesity and fasting

Project description:Obesity-associated metabolic complications are generally considered to emerge from abnormalities in carbohydrate and lipid metabolism, whereas the status of protein metabolism is not well studied. Here, we performed comparative polysome and associated transcriptional profiling analyses to study the dynamics and functional implications of endoplasmic reticulum (ER)-associated protein synthesis in the mouse liver under conditions of obesity and nutrient deprivation. lean wild type and genetically obese (ob/ob) mice with or without overnight fasting were sacrificed with their liver tissues removed. ER-associated polysomes were purified and analyzed by microarray.

Ribosome footprinting in the cytosol and endoplasmic reticulum

Project description:In eukaryotic cells, the spatial regulation of protein expression is frequently conferred through the coupling of mRNA localization and the local control of translation. mRNA localization to the endoplasmic reticulum (ER) is a prominent example of such regulation and serves a ubiquitous role in segregating the synthesis of secretory and integral membrane proteins to the ER. Recent genomic and biochemical studies have now expanded this view to suggest a role for the ER in global protein synthesis. We have utilized cell fractionation and ribosome profiling to obtain a genomic survey of the subcellular organization of mRNA translation and report that ribosomal loading of mRNAs, a proxy for mRNA translation, is biased to the ER. Notably, ER-associated mRNAs encoding both cytosolic and topogenic signal-encoding proteins display similar ribosome loading densities, suggesting that ER-associated ribosomes serve a global role in mRNA translation. We propose that the partitioning of mRNAs and their translation between the cytosol and ER compartments may represent a novel mechanism for the post-transcriptional regulation of gene expression. HEK293 cells were fractionated between the cytosol and endoplasmic reticulum. Within each fraction, ribosome footprints were generated and sequenced. In parallel, total mRNA was sequenced.

Endoplasmic-reticulum calcium depletion and disease.

Project description:The endoplasmic reticulum (ER) as an intracellular Ca(2+) store not only sets up cytosolic Ca(2+) signals, but, among other functions, also assembles and folds newly synthesized proteins. Alterations in ER homeostasis, including severe Ca(2+) depletion, are an upstream event in the pathophysiology of many diseases. On the one hand, insufficient release of activator Ca(2+) may no longer sustain essential cell functions. On the other hand, loss of luminal Ca(2+) causes ER stress and activates an unfolded protein response, which, depending on the duration and severity of the stress, can reestablish normal ER function or lead to cell death. We will review these various diseases by mainly focusing on the mechanisms that cause ER Ca(2+) depletion.

Cytokine-driven glycosphingolipid metabolism modulates endoplasmic reticulum calcium homeostasis in primary human renal mesangial cells

Project description:Glycosphingolipids (GSLs), including hexosylceramides (HexCers), lactosylceramides (LacCers), and gangliosides composed of one or more sugar residues attached to ceramide, are essential components of cell membranes. Dysregulated GSL metabolism has been implicated in various inflammatory and autoimmune diseases, including lupus nephritis; however, its contribution to renal cell dysfunction remains largely unexplored. In this study, we demonstrate that in primary human renal mesangial cells (hRMCs), proinflammatory cytokines relevant to lupus elicit significant upregulation and secretion of inflammatory mediators that parallel intracellular and extracellular accumulation of HexCers and elevated cytosolic calcium (Ca2+) levels. The increase in cytosolic Ca2+ was attributed to a decrease in endoplasmic reticulum (ER) Ca2+ store capacity. Pharmacological inhibition of GSL synthesis with eliglustat significantly reduced HexCers levels and restored ER Ca2+ stores, but did not impact cytokine-induced cytokine/chemokine secretion or cell viability/proliferation. Together, these data suggest that elevated GSL synthesis modulates cytokine-induced ER Ca²⁺ dysregulation in mesangial cells and may play a role in the pathogenesis of lupus nephritis.
