Abstract
G protein-coupled receptors (GPCRs) constitute the largest and most diverse superfamily of mammalian transmembrane proteins. These receptors are involved in a wide range of physiological functions and are targets for more than a third of available drugs in the market. Autophagy is a cellular process involved in degrading damaged proteins and organelles and in recycling cellular components. Deficiencies in autophagy are involved in a variety of pathological conditions. Both GPCRs and autophagy are essential in preserving homeostasis and cell survival. There is emerging evidence suggesting that GPCRs are direct regulators of autophagy. Additionally, autophagic machinery is involved in the regulation of GPCR signalling. The interplay between GPCR and autophagic signalling mechanisms significantly impacts on health and disease; however, there is still an incomplete understanding of the underlying mechanisms and therapeutic implications in different tissues and disease contexts. This review aims to discuss the interactions between GPCR and autophagy signalling. Studies on muscarinic receptors, beta-adrenoceptors, taste receptors, purinergic receptors and adhesion GPCRs are summarized, in relation to autophagy.

[PMID: 37004731 DOI: 10.1016/j.lfs.2023.121644] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 03/06/2023] [Accepted: 03/26/2023] [Indexed: 04/03/2023]
Abstract
Altered sensitivity to the chronotropic and inotropic effects of catecholamines and reduction in β1/β2-adrenoceptor (β1/β2-AR) ratio were reported in failing and in senescent human heart, as well as in isolated atria and ventricle of rats submitted to stress. This was due to downregulation of β1-AR with or without up-regulation of β2-AR. AIMS To investigate the stress-induced behavior of β1-AR in the heart of mice expressing a non-functional β2-AR subtype. The guiding hypothesis is that the absence of β2-AR signaling will not affect the behavior of β1-AR during stress and that those are independent processes. MATERIALS AND METHODS The chronotropic and inotropic responses to β-AR agonists in isolated atria of stressed mice expressing a non-functional β2-AR were analyzed. The mRNA and protein expressions of β1- and β2-AR were also determined. KEY FINDINGS No deaths were observed in mice under stress protocol. Atria of stressed mice displayed reduced sensitivity to isoprenaline compared to the controls, an effect that was abolished by the β2- and β1-AR antagonists 50 nM ICI118,551 and 300 nM CGP20712A, respectively. Sensitivity and maximum response to the β-agonists dobutamine and salbutamol were not altered by stress or ICI118,551. The responses to dobutamine and salbutamol were prevented by CGP20712A. The expression of β1-AR was reduced at protein levels. SIGNIFICANCE Collectively, our data provide evidence that the cardiac β2-AR is not essential for survival in a stressful situation and that the stress-induced reduction of β1-AR expression was independent of the β2-AR presence.

Abstract
The stress response is adaptive and aims to guarantee survival. However, the persistence of a stressor can culminate in pathology. Catecholamines released as part of the stress response over activate beta adrenoceptors (β-AR) in the heart. Whether and how stress affects the expression of components of the intracellular environment in the heart is still, however, unknown. This paper used microarray to analyze the gene expression in the left ventricle wall of rats submitted to foot shock stress, treated or not treated with the selective β2-AR antagonist ICI118,551 (ICI), compared to those of non-stressed rats also treated or not with ICI, respectively. The main findings were that stress induces changes in gene expression in the heart and that β2-AR plays a role in this process. The vast majority of genes disregulated by stress were exclusive for only one of the comparisons, indicating that, in the same stressful situation, the profile of gene expression in the heart is substantially different when the β2-AR is active or when it is blocked. Stress induced alterations in the expression of such a large number of genes seems to be part of stress-induced adaptive mechanism.

Organic chemicals from diesel exhaust particles affects intracellular calcium, inflammation and β-adrenoceptors in endothelial cells. Toxicol Lett 2018; 302:18-27.

Abstract
Exposure to diesel exhaust particles (DEP) may contribute to endothelial dysfunction and cardiovascular disease. DEP, extractable organic material from DEP (DEP-EOM) and certain PAHs seem to trigger [Ca2+]i increase as well as inflammation via GPCRs like βARs and PAR-2. In the present study we explored the involvement of βARs and PAR-2 in effects of DEP-EOM on [Ca2+]i and expression of inflammation-associated genes in the endothelial cell-line HMEC-1. We exposed the human microvascular endothelial cell line HMEC-1 to DEP-EOM fractionated by sequential extraction with solvents of increasing polarity: n-hexane (n-Hex-EOM), dichloromethane (DCM-EOM), methanol (Methanol-EOM) and water (Water-EOM). While Methanol-EOM and Water-EOM had no marked effects, n-Hex-EOM and DCM-EOM enhanced [Ca2+]i (2-3 times baseline) and expression of inflammation-associated genes (IL-1α, IL-1β, COX-2 and CXCL8; 2-15 times baseline) in HMEC-1. The expression of βARs (60-80% of baseline) and βAR-inhibitor carazolol suppressed the increase in [Ca2+]i induced by both n-Hex- and DCM-EOM. Carazolol as well as the Ca2+-channel inhibitor SKF-96365 reduced the DCM-EOM-induced pro-inflammatory gene-expression. Overexpression of βARs increased DCM-EOM-induced [Ca2+]i responses in HEK293 cells, while βAR-overexpression suppressed [Ca2+]i responses from n-Hex-EOM. Furthermore, the PAR-2-inhibitor ENMD-1068 attenuated [Ca2+]i responses to DCM-EOM, but not n-Hex-EOM in HMEC-1. The results suggest that βAR and PAR-2 are partially involved in effects of complex mixtures of chemicals extracted from DEP on calcium signalling and inflammation-associated genes in the HMEC-1 endothelial cell-line.

Abstract
The β3-adrenergic receptor (β3-AR) is an important regulator of various physiological functions, such as thermogenesis in brown adipose tissue, lipolysis in white adipose tissue, negative inotropic effect in cardiomyocyte, and relaxation in blood vessel. The activation of β3-AR by its agonists is shown to have metabolic (antiobesity and antidiabetic) and cardiovascular effects in animal models, highlighting β3-AR as a potential therapeutic target in the treatment of several human diseases. Moreover, a substantial number of studies performed on different populations have identified some β3-AR polymorphic variants associated with obesity, diabetes, cardiovascular diseases, and other disorders. The clinical phenotypes and functional characteristics of these variants provide insights into potential pathophysiological roles of β3-AR in the development of these diseases.

Abstract
In conventional meat-type (British United Turkey (B.U.T.) Big 6) turkey hearts, it has been shown that all cardiac chambers exhibit down-regulation of the β1-adrenoceptors (β1-AR) and concomitantly cAMP accumulation with increasing age regardless of sex. In this study we proved the hypothesis that breed differences exist in age-dependent alterations in the β1-AR system. Right (RA) and left (LA) atrial as well as right (RV) and left (LV) ventricular tissues were collected from male and female Cröllwitzer "wild-type" turkey poults of increasing age (6 wk, 12 wk, 16 wk, 21 wk). The β1-AR density and function were quantified by (-)-[125I]-iodocyanopindolol (ICYP) radioligand binding analysis in cell membranes from 4 cardiac chambers. Basal and stimulated cAMP production was determined as indicator of the receptor function. Wild-type turkeys showed significantly higher heart to body weight ratio than the meat-type B.U.T. Big 6 turkeys. In both sexes of Cröllwitzer turkey hearts, the β1-AR density decreased with age but significance was reached in male cardiac chambers. The receptor affinity (KD) and subtype distribution were not altered. Sex had no effect on age-related decrease in receptor density but had an effect on adenylate cyclase (AC) activity and subsequently cAMP production. In male Cröllwitzer turkey hearts of all ages, cAMP remained at same level, whereas this was even increased in female cardiac chambers. Thus, breed affected age-related receptor-, G-protein and AC-stimulated cAMP formation in normal ventricles and atria, with females exhibiting pronounced increase with age. This suggests that the receptor signaling in wild-type turkey hearts is not as blunted as in hearts of meat-type turkey poults in which stressful farming conditions and fast growing lead to receptor down-regulation.

Abstract
The aim of this work was to investigate if eletroacupuncture at PC6 would modulate the stress-induced anxiety-like behavior and the level of activation of several brain areas. Rats were distributed in groups: control; submitted to immobilization; submitted to immobilization and eletroacupuncture at PC6 or at the tail. Immobilization increased grooming and decreased stretched attend postures and the time spent in the open arms of the ele-vated plus-maze. Eletroacupuncture at PC6 or tail canceled the effect of immobilization on grooming and attenuated the stretched attend posture. Immobilization increased Fos-immunoreactivity in the prefrontal cortex, medial and central amygdala, paraventricular and dorsomedial nuclei of the hypothalamus, lateral hypothalamus, dentate gyrus, CA1, CA2 and CA3 hippocampal areas. The activation of paraventricular, dorsomedial nuclei and prefrontal cortex by immobilization was canceled by electroacupuncture at PC6 and attenuated by electroacupuncture in the tail. The activation of the other areas was canceled by electroacupuncture in PC6 or the tail. It is concluded that immobilization induced anxiety-like behavior that was moderately attenuated by eletroacupuncture with difference between the stimulation in PC6 or the rat tail. Eletroacupuncture showed specificity concerning to the attenuation of the effects of immobilization in the CNS areas related to the stress response, anxiety and cardiovascular system.

Abstract
Decreased responses of the heart to β-adrenoceptor stimulation with aging have been shown to occur merely in selected heart chambers in relation to increased catecholamine levels. However, there are no systematic studies that investigate all cardiac chambers with regard to receptor density and cAMP (adenosine 3', 5'-cyclic monophosphate) responses. We used meat-type turkey poults (British United Turkey (B.U.T.) Big 6) with increasing age because their heart seems to decrease in weight in relation to body weight and they are often used as an animal model for heart failure. The receptor density and distribution were quantified by radioligand binding analysis using (-)-[(125)I]-iodocyanopindolol and β-adrenoceptor subtype-specific antagonists (ICI 118.551 and CGP 20712 A) in membranes of four cardiac chambers (right and left atria and ventricles) of 6-week-, 12-week-, 16/21-week-, and 57-week-old B.U.T. BIG 6 turkeys. Receptor function was determined by measuring basal and stimulated cAMP production. In both sexes, the β-adrenoceptor density decreased significantly in all chambers with age without altered β-adrenoceptor subtype distribution. The receptor affinity (KD) to the radioligand was similar in hearts of all age groups. β-adrenoceptor-(isoproterenol and guanosine 5'-triphosphate), G-protein-(NaF) and catalytic unit of adenylate cyclase (forskolin, Mn(2+)) mediated cAMP responses were not chamber-dependent. Indeed, the cAMP level was significantly lower in 57-week-old hearts than in 6-week-, 12-week-, 16/21-week-old hearts. These data suggest that with increasing age and body weight, the β-adrenoceptor signal transduction pathway was highly blunted in all cardiac chambers, occurring by decreased receptor density and cAMP responses.

Abstract
It is thought that vitamin C has protective roles on stress-induced heart damage and the development of cardiovascular diseases, but its precise role and mechanisms are unclear. In the present study, we investigated the specific mechanisms by which vitamin C leads to protecting the heart from stress-induced damage in the Gulo(-/-) mice which cannot synthesize vitamin C like humans. By exposure to stress (1h/day), the heartbeat and cardiac output in vitamin C-insufficient Gulo(-/-) mice were definitely decreased, despite a significant increase of adrenaline (ADR) and noradrenaline (NA) production. A change of cardiac structure caused by the death of cardiomyocytes and an increased expression of matrix metalloprotease (MMP)-2 and -9 were also found. Moreover, lipid peroxidation and the production of tumor necrosis factor-alpha (TNF-α) in the heart were increased. Finally, all vitamin C-insufficient Gulo(-/-) mice were expired within 2 weeks. Interestingly, all of the findings in vitamin C-insufficient Gulo(-/-) mice were completely prevented by the supplementation of a sufficient amount of vitamin C. Taken together, vitamin C insufficiency increases the risk of stress-induced cardiac damage with structural and functional changes arising from the apoptosis of cardiomyocytes.

JOURNAL OF ETHNOPHARMACOLOGY 2013; 147:447-55.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese Medicine (TCM) operates on the general principle that compatible components of different herbal decoction may work together to synergistically enhance therapeutic efficacy or reduce adverse effects. Cortex Periplocae is an herb that has been used in TCM clinics for a long time in the treatment of chronic heart failure. However, recently, the use of this herb has been restricted because of widespread abuse and misapplications. Radix Notoginseng is another herb that is used in TCM because of its protective role on cardiomyocytes. From our previous studies on these two herbs in a mouse model, we observed an increased LD50 after oral administration of Cortex Periplocae extract (CPE) and Panax notoginseng saponins (PNS) in a ratio of 1:1 compared with Cortex Periplocae extract used alone. AIM OF THE STUDY This study aimed to investigate whether there are mutual synergistic effects of the two herbal extracts, CPE and PNS, on catecholamines (CAs) secretion, and their possible underlying mechanism(s) for such effects. MATERIALS AND METHODS CPE and PNS were quantified by the LC-MS/MS method. HPLC-ECD was used to determine the CAs secreted into the medium by bovine adrenal medulla cells (BAMCs) and calcium influx was measured using a Calcium 4 reagent kit. RESULTS We found that the stimulatory effect of CPE on CAs secretion was inhibited when used together with PNS. For a better clarification of the different constituents of the extracts, a quantitative analysis was carried out. Periplocin was found to be the main active component of CPE valued as 0.99% and saponins were the principal constituents of PNS. These results also showed that CPE increased the secretion of CAs in a dose-dependent manner while the actions of PNS were seen to be inhibitory. Periplocin monomer of CPE could be implicated for the actions of CPE since it plays the role of increasing the ACh-induced CAs secretion in a calcium-dependent manner. We therefore conclude that; CPE and PNS exert antagonistic effects in regulating the concentration of intracellular calcium. CONCLUSIONS PNS inhibits CPE-induced CAs secretion by suppressing calcium influx in bovine adrenal medulla cells while periplocin, one of the main components of CPE has the same secretagogue effect as CPE.

Abstract
The importance of adrenergic pathways in cancer has long been suspected, but now there is mounting epidemiological, preclinical, and clinical evidence of its importance in gynecologic cancers. To date, most of these effects are mediated primarily through the beta 2 adrenergic receptor activation of the tumor cell cyclic AMP-protein kinase A signaling pathway. This review will discuss the current knowledge about the neuroendocrine stress response in gynecologic tumor biology.

Abstract
Stress exposure activates the sympathoneural system, resulting in catecholamine release. Chronic stress is associated with development of numerous disorders, including cardiovascular diseases. Here we investigated the expression of mRNAs for catecholamine biosynthetic enzymes tyrosine-hydroxylase, dopamine-beta-hydroxylase and phenylethanolamine N-methyl-transferase, and for beta(1)- and beta(2)-adrenoceptors in the right and left ventricles of rats exposed to chronic unpredictable mild stress. The tyrosine-hydroxylase and dopamine-beta-hydroxylase mRNA levels were not affected by stress, whereas the phenylethanolamine N-methyltransferase mRNA levels significantly increased in both right and left ventricles. No changes in beta(1)-adrenoceptor mRNA levels in either right or left ventricles were observed. At the same time, stress produced a significant increase of beta(2)-adrenoceptor mRNA levels in left ventricles. These results suggest that elevated expression of phenylethanolamine N-methyltransferase in both ventricules and beta(2)-adrenoceptor genes in left ventricles could provide a molecular mechanism that leads to altered physiological response, which is important for the organism coping with stress.

Abstract
AIMS AND OBJECTIVES To critically review evidence on the effects of psychological support during intensive care unit (ICU) treatment on adult ICU patients' psychological and physiological outcomes. Evidence from intervention studies on imagery and relaxation has been included, as well. BACKGROUND Stress and negative emotions may have both immediate, as well as long-term effects on ICU patients' psychological and physical well-being, and they are linked to delayed physical recovery. DESIGN, METHODS: A narrative critical review methodology was employed. Databases searched included Medline, CINAHL, PubMed, PsychInfo and the Cochrane Library. Experimental, quasi-experimental or pretest-posttest peer-reviewed intervention studies published since 1970 were included. RESULTS Fourteen studies: seven on nurse led relaxation, three on guided imagery, one on nurse-patient interaction, two on physician-patient interaction and one correlational study on perceived social support were included. The results suggest significant improvements in patients' outcomes: improved vital signs, decrease in pain ratings, anxiety, rate of complications and length of stay, and improved sleep and patient satisfaction. Eight studies employed randomized experimental, four quasi-experimental and two descriptive correlational designs. Two studies explored effects on patients' sleep, and two on procedure-related pain. CONCLUSIONS The literature is limited in exploring the effects of nurse-patient interactions. The amount and quality of psychosocial support in the ICU, as well as imagery and relaxation techniques, are linked to short-term and long-term patients' outcomes. RELEVANCE TO CLINICAL PRACTICE ICU nurses need to engage in psychological support in a systematic way, and to acknowledge the high priority of support interventions.

Abstract
Various stressful stimuli are known to activate the sympathetic nervous system to release catecholamines and the hypothalamic-pituitary-adrenal axis to release glucocorticoids in the circulation. Although initial actions of both catecholamines and glucocorticoids are beneficial for the function of the cardiovascular system, their delayed effects on the heart are deleterious. Glucocorticoids not only increase plasma levels of catecholamines by inhibiting their extraneuronal uptake, but they have also been shown to induce supersensitivity to catecholamines in the heart by upregulating different components of the betta-adrenoceptor signal transduction system. Low concentrations of catecholamines stimulate the heart by promoting Ca2+ movements, whereas excessive amounts of catecholamines produce cardiac dysfunction by inducing intracellular Ca2+ overload in cardiomyocytes. Several studies have shown, however, that under stressful conditions high concentrations of catecholamines become oxidized to form aminolutins and generate oxyradicals. These oxidation products of catecholamines have been demonstrated to produce coronary spasm, arrhythmias, and cardiac dysfunction by inducing Ca2+-handling abnormalities in both sarcolemmal and sarcoplasmic reticulum, defects in energy production by mitochondria, and myocardial cell damage. In this article we have focused the discussion to highlight the interrelationship between catecholamines and glucocorticoids and to emphasize the role of oxidation products of catecholamines in the development of stress-induced heart disease.

Abstract
Exposure to stressors has been shown to change atrial responsiveness to catecholamines, but it is not clear yet how it affects the ventricular myocardium, which plays a major role in the catecholamine-stimulated increase in cardiac output. Adult male rats were submitted to restraint (RST) or footshock (FS) sessions for 3 days. Reactivity to agonists of the beta-adrenergic pathway was analyzed in left ventricular myocytes isolated from stressed and control rats (CTR). Whereas no significant changes were detected after RST, enhancement of catecholamine-induced spontaneous activity, accompanied by decrease in inotropic maximal response, was observed in myocytes from FS rats. Changes were reversed by beta(1)-, but not by alpha(1)-or beta(2)-adrenoceptor (AR) blockade. Similar alterations were seen in response to forskolin. However, responsiveness to 3-isobutyl-1-methylxanthine and CaCl(2) was comparable in control and FS groups. A significant negative correlation was observed between the maximally stimulated spontaneous activity rate and contraction amplitude. Results indicate that: (a) enhanced automatism during adrenergic stimulation of myocytes from FS rats is mediated by beta(1)-ARs and seems to involve post-receptor mechanisms, probably decreased cAMP degradation; (b) the exaggerated spontaneous activity, which may contribute to generation of catecholaminergic arrhythmias, might limit the development of the inotropic response.

Abstract
Several cardiovascular disorders have been related to alterations in beta-adrenoceptor (beta-AR) signaling at or beyond the receptor level. During the stress reaction, the sympathetic-adrenal medullary system and the hypothalamus-pituitary-adrenal cortex axis are activated, causing beta-AR overstimulation and remodeling of the beta(1)/beta(2)/beta(3)-AR ratio in cardiomyocytes. In a model of foot-shock stress, we described decreased beta(1)-AR signaling occurring simultaneously with increased beta(2)-AR signaling, whereas the response to the nonconventional agonist, CGP12177, was not altered. These alterations may play an adaptive role to the increased sympathetic drive to the heart, protecting the cardiac tissue from the cardiotoxic effects mediated by beta(1)-ARs overstimulation without altering cardiac output, since this would be sustained by the beta(2)-AR, which would also protect myocytes from apoptosis. Moreover, the selective enhancement of the beta(2)-AR population might help to diminish the risk of overstimulation since this adrenoceptor subtype couples to both, stimulatory G (Gs) and inhibitory G (Gi) proteins. On the other hand, in the model of neurogenic hypertension, the decrease in beta(1)-AR-mediated response is not followed by increase in the beta(2)-AR-mediated response. However, the response to CGP12177, which was desensitized 48 h after the surgery, was normalized 7 days after that, when beta(1)-AR were downregulated. Therefore, both experimental models provided evidence that the classical isoform of beta(1)-AR and the recently described low-affinity isoform of beta(1)-AR show independent behavior and provide the heart with adaptive mechanisms to increased sympathetic stimulation during stress.

Abstract
Hawthorn (Crataegus spp.) plant extract is used as a herbal alternative medicine for the prevention and treatment of various cardiovascular diseases. Recently, it was shown that hawthorn extract preparations caused negative chronotropic effects in a cultured neonatal murine cardiomyocyte assay, independent of beta-adrenergic receptor blockade. The aim of this study was to further characterize the effect of hawthorn extract to decrease the contraction rate of cultured cardiomyocytes. To test the hypothesis that hawthorn is acting via muscarinic receptors, the effect of hawthorn extract on atrial versus ventricular cardiomyocytes in culture was evaluated. As would be expected for activation of muscarinic receptors, hawthorn extract had a greater effect in atrial cells. Atrial and/or ventricular cardiomyocytes were then treated with hawthorn extract in the presence of atropine or himbacine. Changes in the contraction rate of cultured cardiomyocytes revealed that both muscarinic antagonists significantly attenuated the negative chronotropic activity of hawthorn extract. Using quinuclidinyl benzilate, L-[benzylic-4,4'-(3)H] ([(3)H]-QNB) as a radioligand antagonist, the effect of a partially purified hawthorn extract fraction to inhibit muscarinic receptor binding was quantified. Hawthorn extract fraction 3 dose-dependently inhibited [(3)H]-QNB binding to mouse heart membranes. Taken together, these findings suggest that decreased contraction frequency by hawthorn extracts in neonatal murine cardiomyocytes may be mediated via muscarinic receptor activation.

Abstract
There is strong evidence about the importance of catecholamines and calcium signaling in heart function. Also, interaction of these two systems is well documented. Catecholamines signal through adrenergic receptors, and further activate calcium transport either from the extracellular space, or from the intracellular calcium stores. This review summarizes current knowledge on catecholamine production in the heart, with special focus on the final enzyme in the catecholamine synthesizing pathway, phenylethanolamine N-methyltransferase (PNMT), in different cell types in the heart. Further, signaling through different types of adrenergic receptors in physiological conditions and after exposure to different stressors is discussed. Also, part of this review considers activation of an intracellular calcium transport system via inositol 1,4,5-trisphosphate receptor and to possible functional consequences in control and stress conditions.
