Abstract
Ion channels and transporters are ubiquitously expressed on cell membrane, which involve in a plethora of physiological process such as contraction, neurotransmission, secretion and so on. Ion channels and transporters is of great importance to maintaining membrane potential homeostasis, which is essential to absorption of nutrients in gastrointestinal tract. Most of nutrients are electrogenic and require ion channels and transporters to absorb. This review summarizes the latest research on the role of ion channels and transporters in regulating nutrient uptake such as K+ channels, Ca2+ channels and ion exchangers. Revealing the mechanism of ion channels and transporters associated with nutrient uptake will be helpful to provide new methods to diagnosis and find potential targets for diseases like diabetes, inflammatory bowel diseases, etc. Even though some of study still remain ambiguous and in early stage, we believe that ion channels and transporters will be novel therapeutic targets in the future.

Abstract
INTRODUCTION Asthma is a chronic lung disease influenced by environmental and inflammatory triggers and involving complex signaling pathways across resident airway cells such as epithelium, airway smooth muscle, fibroblasts, and immune cells. While our understanding of asthma pathophysiology is continually progressing, there is a growing realization that cellular microdomains play critical roles in mediating signaling relevant to asthma in the context of contractility and remodeling. Mechanosensitive pathways are increasingly recognized as important to microdomain signaling, with Piezo and transient receptor protein (TRP) channels at the plasma membrane considered important for converting mechanical stimuli into cellular behavior. Given their ion channel properties, particularly Ca2+ conduction, a question becomes whether and how mechanosensitive channels contribute to Ca2+ microdomains in airway cells relevant to asthma. AREAS COVERED Mechanosensitive TRP and Piezo channels regulate key Ca2+ regulatory proteins such as store operated calcium entry (SOCE) involving STIM and Orai channels, and sarcoendoplasmic (SR) mechanisms such as IP3 receptor channels (IP3Rs), and SR Ca2+ ATPase (SERCA) that are important in asthma pathophysiology including airway hyperreactivity and remodeling. EXPERT OPINION Physical and/or functional interactions between Ca2+ regulatory proteins and mechanosensitive channels such as TRP and Piezo can toward understanding asthma pathophysiology and identifying novel therapeutic approaches.

[PMID: 37289063 PMCID: PMC10308943 DOI: 10.1128/jvi.00495-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2023] [Accepted: 05/18/2023] [Indexed: 06/09/2023] Open
Abstract
Viral diseases are a significant risk to the aquaculture industry. Transient receptor potential vanilloid 4 (TRPV4) has been reported to be involved in regulating viral activity in mammals, but its regulatory effect on viruses in teleost fish remains unknown. Here, the role of the TRPV4-DEAD box RNA helicase 1 (DDX1) axis in viral infection was investigated in mandarin fish (Siniperca chuatsi). Our results showed that TRPV4 activation mediates Ca2+ influx and facilitates infectious spleen and kidney necrosis virus (ISKNV) replication, whereas this promotion was nearly eliminated by an M709D mutation in TRPV4, a channel Ca2+ permeability mutant. The concentration of cellular Ca2+ increased during ISKNV infection, and Ca2+ was critical for viral replication. TRPV4 interacted with DDX1, and the interaction was mediated primarily by the N-terminal domain (NTD) of TRPV4 and the C-terminal domain (CTD) of DDX1. This interaction was attenuated by TRPV4 activation, thereby enhancing ISKNV replication. DDX1 could bind to viral mRNAs and facilitate ISKNV replication, which required the ATPase/helicase activity of DDX1. Furthermore, the TRPV4-DDX1 axis was verified to regulate herpes simplex virus 1 replication in mammalian cells. These results suggested that the TRPV4-DDX1 axis plays an important role in viral replication. Our work provides a novel molecular mechanism for host involvement in viral regulation, which would be of benefit for new insights into the prevention and control of aquaculture diseases. IMPORTANCE In 2020, global aquaculture production reached a record of 122.6 million tons, with a total value of $281.5 billion. Meanwhile, frequent outbreaks of viral diseases have occurred in aquaculture, and about 10% of farmed aquatic animal production has been lost to infectious diseases, resulting in more than $10 billion in economic losses every year. Therefore, an understanding of the potential molecular mechanism of how aquatic organisms respond to and regulate viral replication is of great significance. Our study suggested that TRPV4 enables Ca2+ influx and interactions with DDX1 to collectively promote ISKNV replication, providing novel insights into the roles of the TRPV4-DDX1 axis in regulating the proviral effect of DDX1. This advances our understanding of viral disease outbreaks and would be of benefit for studies on preventing aquatic viral diseases.

Abstract
TRP channels are expressed both in vascular myocytes and endothelial cells, but knowledge of their operational mechanisms in vascular tissue is particularly limited. Here, we show for the first time the biphasic contractile reaction with relaxation followed by a contraction in response to TRPV4 agonist, GSK1016790A, in a rat pulmonary artery preconstricted with phenylephrine. Similar responses were observed both with and without endothelium, and these were abolished by the TRPV4 selective blocker, HC067047, confirming the specific role of TRPV4 in vascular myocytes. Using selective blockers of BKCa and L-type voltage-gated Ca2+ channels (CaL), we found that the relaxation phase was inducted by BKCa activation generating STOCs, while subsequent slowly developing TRPV4-mediated depolarisation activated CaL, producing the second contraction phase. These results are compared to TRPM8 activation using menthol in rat tail artery. Activation of both types of TRP channels produces highly similar changes in membrane potential, namely slow depolarisation with concurrent brief hyperpolarisations due to STOCs. We thus propose a general concept of bidirectional TRP-CaL-RyR-BKCa molecular and functional signaloplex in vascular smooth muscles. Accordingly, both TRPV4 and TRPM8 channels enhance local Ca2+ signals producing STOCs via TRP-RyR-BKCa coupling while simultaneously globally engaging BKCa and CaL channels by altering membrane potential.

Abstract
Oral glutamine (Gln) has been widely used in gastrointestinal (GI) clinical practice, but it is unclear if Ca2+ regulates intestinal Gln transport, although both of them are essential nutrients for mammals. Chambers were used to determine Gln (25 mM)-induced Isc through Na+/Gln co-transporters in the small intestine in the absence or the presence of selective activators or blockers of ion channels and transporters. Luminal but not serosal application of Gln induced marked intestinal Isc, especially in the distal ileum. Lowering luminal Na+ almost abolished the Gln-induced ileal Isc, in which the calcium-sensitive receptor (CaSR) activation were not involved. Ca2+ removal from both luminal and serosal sides of the ileum significantly reduced Gln- Isc. Blocking either luminal Ca2+ entry via the voltage-gated calcium channels (VGCC) or endoplasmic reticulum (ER) release via inositol 1,4,5-triphosphate receptor (IP3R) and ryanodine receptor (RyR) attenuated the Gln-induced ileal Isc, Likewise, blocking serosal Ca2+ entry via the store-operated Ca2+ entry (SOCE), TRPV1/2 channels, and Na+/Ca2+ exchangers (NCX) attenuated the Gln-induced ileal Isc. In contrast, activating TRPV1/2 channels enhanced the Gln-induced ileal Isc. We concluded that Ca2+ signaling is critical for intestinal Gln transport, and multiple plasma membrane Ca2+-permeable channels and transporters play roles in this process. The Ca2+ regulation of ileal Na+/Gln transport expands our understanding of intestinal nutrient uptake and may be significant in GI health and disease.

Abstract
Transient receptor potential (TRP) ion channels play critical roles in physiological and pathological conditions. Increasing evidence has unveiled the contribution of TRP vanilloid (TRPV) family in the development of asthma. The TRPV family is a group (TRPV1-TRPV6) of polymodal channels capable of sensing thermal, acidic, mechanical stress, and osmotic stimuli. TRPVs can be activated by endogenous ligands including, arachidonic acid derivatives or endocannabinoids. While TRPV1-TRPV4 are non-selective cation channels showing a predominance for Ca2+ over Na + influx, TRPV5 and TRPV6 are only Ca2+ permeable selective channels. Asthma is a chronic inflammatory bronchopulmonary disorder involving airway hyperresponsiveness (AHR) and airway remodeling. Patients suffering from allergic asthma display an inflammatory pattern driven by cytokines produced in type-2 helper T cells (Th2) and type 2 innate lymphoid cells (ILC2s). Ion channels are essential regulators in airway smooth muscle (ASM) and immune cells physiology. In this review, we summarize the contribution of TRPV1, TRPV2, and TRPV4 to the pathogenesis of asthma. TRPV1 is associated with hypersensitivity to environmental pollutants and chronic cough, inflammation, AHR, and remodeling. TRPV2 is increased in peripheral lymphocytes of asthmatic patients. TRPV4 contributes to ASM cells proliferation, and its blockade leads to a reduced eosinophilia, neutrophilia, as well as an abolished AHR. In conclusion, TRPV2 may represent a novel biomarker for asthma in children; meanwhile, TRPV1 and TRPV4 seem to be essential contributors to the development and exacerbations of asthma. Moreover, these channels may serve as novel therapeutic targets for this ailment.

Abstract
INTRODUCTION Diabetes-associated endothelial barrier function impairment might be linked to disturbances in Ca2+ homeostasis. To study the role and molecular mechanism of Orais-vascular endothelial (VE)-cadherin signaling complex and its downstream signaling pathway in diabetic endothelial injury using mouse aortic endothelial cells (MAECs). RESEARCH DESIGN AND METHODS The activity of store-operated Ca2+ entry (SOCE) was detected by calcium imaging after 7 days of high-glucose (HG) or normal-glucose (NG) exposure, the expression levels of Orais after HG treatment was detected by western blot analysis. The effect of HG exposure on the expression of phosphorylated (p)-VE-cadherin and VE-cadherin on cell membrane was observed by immunofluorescence assay. HG-induced transendothelial electrical resistance was examined in vitro after MAECs were cultured in HG medium. FD-20 permeability was tested in monolayer aortic endothelial cells through transwell permeability assay. The interactions between Orais and VE-cadherin were detected by co-immunoprecipitation and immunofluorescence technologies. Immunohistochemical experiment was used to detect the expression changes of Orais, VE-cadherin and p-VE-cadherin in aortic endothelium of mice with diabetes. RESULTS (1) The expression levels of Orais and activity of SOCE were significantly increased in MAECs cultured in HG for 7 days. (2) In MAECs cultured in HG for 7 days, the ratio of p-VE-cadherin to VE-cadherin expressed on the cell membrane and the FD-20 permeability in monolayer endothelial cells increased, indicating that intercellular permeability increased. (3) Orais and VE-cadherin can interact and enhance the interaction ratio through HG stimulation. (4) In MAECs cultured with HG, the SOCE activator ATP enhanced the expression level of p-VE-cadherin, and the SOCE inhibitor BTP2 decreased the expression level of p-VE-cadherin. (5) Significantly increased expression of p-VE-cadherin and Orais in the aortic endothelium of mice with diabetes. CONCLUSION HG exposure stimulated increased expression of Orais in endothelial cells, and increased VE-cadherin phosphorylation through Orais-VE-cadherin complex and a series of downstream signaling pathways, resulting in disruption of endothelial cell junctions and initiation of atherosclerosis.

Abstract
Excessive stress response causes disability in social life. There are many diseases
caused by stress, such as gastrointestinal motility disorders, depression, eating
disorders, and cardiovascular diseases. Transient receptor potential (TRP) channels
underlie non-selective cation currents and are downstream effectors of G protein-coupled
receptors. Ca2+ influx is important for smooth muscle contraction, which is
responsible for gastrointestinal motility. Little is known about the possible involvement
of TRP channels in the gastrointestinal motility disorders due to stress. The purpose of
this study was to measure the changes in gastrointestinal motility caused by stress and to
elucidate the mechanism of these changes. The stress model used the water immersion
restraint stress. Gastrointestinal motility, especially the ileum, was recorded responses
to electric field stimulation (EFS) by isometric transducer. EFS-induced contraction was
significantly reduced in the ileum of stressed mouse. Even under the conditions treated
with atropine, EFS-induced contraction was significantly reduced in the ileum of stressed
mouse. In addition, carbachol-induced, neurokinin A-induced, and substance P-induced
contractions were all significantly reduced in the ileum of stressed mouse. Furthermore,
the expression of TRPC3 was decreased in the ileum of stressed mouse. These results
suggest that the gastrointestinal motility disorders due to stress is associated with
specific non-selective cation channel.

Abstract
INTRODUCTION Diabetes-associated endothelium dysfunction might be linked to disturbances in Ca2+ homeostasis. Our main objective is to reveal the potential mechanisms by which high-glucose (HG) exposure promotes increased proliferation of human coronary artery endothelial cells (HCAECs) in culture, and that store-operated Ca2+ entry (SOCE) and insulin-like growth factor binding protein 3 (IGFBP3) contribute to this proliferation. RESEARCH DESIGN AND METHODS We detected the expression levels of Ca2+ release-activated calcium channel proteins (Orais), IGFBP3 and proliferating cell nuclear antigen of HCAECs cultured in HG medium for 1, 3, 7, and 14 days and in streptozotocin-induced diabetic mouse coronary endothelial cells. Coimmunoprecipitation and immunofluorescence technologies were used to detect the interactions between Orais and IGFBP3 of HCAECs exposed to HG environment, and to detect IGFBP3 expression and proliferation after treatment of HCAECs cultured in HG medium with an agonist or inhibitor of SOCE. Similarly, after transfection of specific small interfering RNA to knock down IGFBP3 protein expression, SOCE activity and Orais expression were tested. Some processes related to endothelial dysfunction, such as migration, barrier function and adhesion marker expression, are also measured. RESULTS HG exposure promoted increased proliferation of HCAECs in culture and that SOCE and IGFBP3 contributed to this proliferation. In addition, we also found that Orais and IGFBP3 were physically associated and regulated each other's expression levels. Besides, their expression levels and interactions were enhanced in HCAECs after exposure to HG. HG exposure promotes cell migration, but reduces barrier function and adherens junction protein expression levels in HCAECs. CONCLUSION Orais and IGFBP3 formed a signaling complex that mediated HCAEC proliferation during HG exposure in culture. Meanwhile, we also found that SOCE stimulates proliferation of HCAECs by regulating IGFBP3, thereby promoting the occurrence and progression of coronary atherosclerosis in diabetes. It is worth noting that our findings may shed new light on the mechanisms of increased proliferation in HCAECs in diabetes and suggest the potential value of SOCE and IGFBP3 as therapeutic targets for coronary atherosclerosis in individuals with diabetes.

Liu N, Liu J, Wen X, Bai L, Shao R, Bai J. TRPV4 contributes to ER stress: Relation to apoptosis in the MPP +-induced cell model of Parkinson's disease. Life Sci 2020; 261:118461. [PMID: 32961227 DOI: 10.1016/j.lfs.2020.118461] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2020] [Revised: 09/04/2020] [Accepted: 09/15/2020] [Indexed: 12/24/2022]
Abstract
AIMS Parkinson's disease (PD) is a multifactorial neurodegenerative disorder. Its molecular mechanism is still unclear. Endoplasmic reticulum (ER) stress has been highlighted in PD. Transient receptor potential vanilloid 4 (TRPV4) is a kind of nonselective calcium cation channel. A defined role for TRPV4 in PD has not been reported. The purpose of the present research was to investigate the molecular mechanisms by which TRPV4 regulates ER stress induced by the 1-methyl-4-phenylpyridinium ion (MPP+) in PC12 cells. MAIN METHODS PC12 cells were pretreated with the TRPV4-specific antagonist HC067047 or transfected with TRPV4 siRNA followed by treatment with MPP+. Cell viability was measured by the CCK-8 Assay. The expression of TRPV4, sarco/endoplasmic reticulum Ca2+-ATPase 2 (SERCA2), glucose-regulated protein 78 (GRP78), glucose-regulated protein 94 (GRP94), C/EBP homologous protein (CHOP), procaspase-12, and tyrosine hydroxylase (TH) was detected by western blot and RT-PCR. KEY FINDINGS The expression of TRPV4 was upregulated, while cell viability was decreased by MPP+, which was reversed by HC067047. The ER stress common molecular signature SERCA2 was depressed by MPP+. Moreover, MPP+ induced upregulation of GRP78, GRP94, CHOP, and decrease in procaspase-12 and TH. HC067047 and TRPV4 siRNA reversed MPP+-induced ER stress and restored TH production. SIGNIFICANCE TRPV4 functions upstream of ER stress induced by MPP+ and holds promise as a prospective pharmacotherapy target for PD.
