Deciphering the antidepressant effects of Rosa damascena essential oil mediated through the serotonergic synapse signaling pathway. JOURNAL OF ETHNOPHARMACOLOGY 2024; 328:118007. [PMID: 38492791 DOI: 10.1016/j.jep.2024.118007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 02/08/2024] [Accepted: 03/02/2024] [Indexed: 03/18/2024]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rosa damascena is an ancient plant with significance in both medicine and perfumery that have a variety of therapeutic properties, including antidepressant, anti-anxiety, and anti-stress effects. Rose damascena essential oil (REO) has been used to treat depression, anxiety and other neurological related disorders in Iranian traditional medicine. However, its precise mechanism of action remains elusive. AIM OF THE STUDY The aim of this study was to investigate the impact and mechanism underlying the influence of REO on chronic unpredictable mild stress (CUMS) rats. MATERIALS AND METHODS Gas chromatography-mass spectrometry (GC-MS) technique coupling was used to analyze of the components of REO. A CUMS rat model was replicated to assess the antidepressant effects of varying doses of REO. This assessment encompassed behavioral evaluations, biochemical index measurements, and hematoxylin-eosin staining. For a comprehensive analysis of hippocampal tissues, we employed transcriptomics and incorporated weighting coefficients by means of network pharmacology. These measures allowed us to explore differentially expressed genes and biofunctional pathways affected by REO in the context of depression treatment. Furthermore, GC-MS metabolomics was employed to assess metabolic profiles, while a joint analysis in Metscape facilitated the construction of a network elucidating the links between differentially expressed genes and metabolites, thereby elucidating potential relationships and clarifying key pathways regulated by REO. Finally, the expression of relevant proteins in the key pathways was determined through immunohistochemistry and Western blot analysis. Molecular docking was utilized to investigate the interactions between active components and key targets, thereby validating the experimental results. RESULTS REO alleviated depressive-like behavior, significantly elevated levels of the neurotransmitter 5-hydroxytryptamine (5-HT), and reduced hippocampal neuronal damage in CUMS rats. This therapeutic effect may be associated with the modulation of the serotonergic synapse signaling pathway. Furthermore, REO rectified metabolic disturbances, primarily through the regulation of amino acid metabolic pathways. Joint analysis revealed five differentially expressed genes (EEF1A1, LOC729197, ATP8A2, NDST4, and GAD2), suggesting their potential in alleviating depressive symptoms by modulating the serotonergic synapse signaling pathway and tryptophan metabolism. REO also modulated the 5-HT2A-mediated extracellular regulated protein kinases-cAMP-response element binding protein-brain-derived neurotrophic factor (ERK-CREB-BDNF) pathway. In addition, molecular docking results indicated that citronellol, geraniol and (E,E)-farnesol in REO may serve as key active ingredients responsible for its antidepressant effects. CONCLUSIONS This study is the first to report that REO can effectively alleviate CUMS-induced depression-like effects in rats. Additionally, the study offers a comprehensive understanding of its intricate antidepressant mechanism from a multi-omics and multi-level perspective. Our findings hold promise for the clinical application and further development of this essential oil.

Rose essential oil diminishes dopaminergic neuron degenerations and reduces α-synuclein aggregation in Caenorhabditis elegans models of Parkinson's disease. Phytother Res 2023. [PMID: 36920348 DOI: 10.1002/ptr.7783] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 10/10/2022] [Accepted: 01/29/2023] [Indexed: 03/16/2023]
Abstract
Parkinson's disease (P.D.) is the second most progressive neurodegenerative disorder in the elderly. Degeneration of dopaminergic (DA) neurons and α-synuclein (α-Syn) accumulated toxicity is the major contributor to this disease. At present, the disease has no effective treatment. Many recent studies focus on identifying novel therapeutics that provide benefits to stop the disease progression in P.D. patients. Screening novel and effective drugs in P.D. animal models is time- and cost-consuming. Rose Essential Oil (REO) extracted from Rosa Rugosa species (R. Setate × R. Rugosa). REO contains Citronellol, Geraniol, and Octadiene that possess anti-Aβ, anti-oxidative, and anti-depression-like properties, but no reports have defined the REO effect on P.D. yet. The present study examines the REO neuroprotective potential in transgenic Caenorhabditis elegans P.D. models. We observed that REO reduced α-Syn aggregations and diminished DA neuron degenerations induced by 6-OHDA, reduced food-sensing behavioural disabilities, and prolonged the lifespan of the nematode. Moreover, REO augmented the chymotrypsin-like proteasome and SOD-3 activities. Further, we observed the anti-oxidative role of REO by reducing internal cells ROS. Together, these findings supported REO as an anti-PD drug and may exert its effects by lowering oxidative stress via the anti-oxidative pathway.

Abstract
Background Multiple sclerosis (MS) is the most prevalent neurological disability of young adults. Anti-inflammatory drugs have relative effects on MS. The anti-inflammatory and antioxidative effects of Zingiber officinale (ginger) have been proven in some experimental and clinical investigations. The aim of this study was to evaluate the effects of ginger extract on preventing myelin degradation in a rat model of MS. Methods Forty nine male Wistar rats were used in this study and divided into four control groups: the normal group, cuprizone-induced group, sham group (cuprizone [CPZ] + sodium carboxymethyl cellulose [NaCMC]), standard control group (fingolimod + cuprizone), including three experimental groups of CPZ, each receiving three different doses of ginger extract: 150, 300, and 600mg/kg /kg/day. Results Ginger extract of 600 mg/kg prevented corpus callosum from demyelination; however, a significant difference was observed in the fingolimod group (p < 0.05). Difference in the CPZ group was quite significant (p < 0.05). Conclusion Treatment with ginger inhibited demyelination and alleviated remyelination of corpus callosum in rats. Therefore, it could serve as a therapeutic agent in the MS.

Rosa Damascena mill for treating adults' anxiety, depression, and stress: A systematic review and dose-response meta-analysis of randomized controlled trials. Phytother Res 2021; 35:6585-6606. [PMID: 34405933 DOI: 10.1002/ptr.7243] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2020] [Revised: 07/13/2021] [Accepted: 08/02/2021] [Indexed: 12/23/2022]
Abstract
Recent studies have reported conflicting findings on the antianxiety, antidepressant, and anti-stress properties of Rosa Damascena Mill (RDM). Therefore, the present systematic review and meta-analysis were conducted on the effects of RDM for treating anxiety, depression, and stress amongst adults. The online data sources of Cochrane Central Register of Controlled Trials, PubMed, Scopus, Web of Science, Embase, ProQuest, and Scientific Information Database were searched from inception to June 30, 2021. The randomized controlled trials (RCTs), which examined the effects of RDM (in any form of administration) on adults' anxiety, depression, and stress, were included. A random-effects model was applied to pool the data, and a total of 32 publications were included. The results of the meta-analysis revealed that administration of RDM significantly reduced state anxiety (effect size [ES]: 24, standardized mean difference [SMD]: -1.74, 95% confidence interval [CI]: -2.29, -1.20; p < .001), depression (ES: 7, SMD: -0.87, 95% CI: -1.47, -0.28; p = .004), and stress (ES: 4, SMD: -1.33, 95% CI: -1.98, -0.69; p < .001). However, the treatment had no significant effect on trait anxiety (ES: 6, weighted mean difference: -0.75, 95% CI: -1.93, 0.43; p = .214). The association between the total administration dosage and/or duration of RDM and the changes in state anxiety and depression was not dose-dependent. Most RCTs had a fair methodological quality based on the Cochrane risk of bias assessment tool. Besides, the quality of evidence ranged from very low to moderate according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Hence, further high-quality RCTs are needed to draw reliable conclusions regarding the use of RDM for treating adults' anxiety, depression, and stress.

Abstract
There is an intense search for natural compounds that can inhibit the oligomerization and fibrillation of α-synuclein (α-Syn), whose aggregation is key to the development of Parkinson's disease (PD). Rosa damascena is a medicinal herb widely used in Middle Eastern food, ceremonies, and perfumes. The herb is known to contain many different polyphenols. Here we investigated the existence of α-Syn fibrillation inhibitors in R. damascena extract. Different HPLC fractions of the extract were assessed in α-Syn fibrillation and toxicity assays. The most active fractions led to the formation of more α-Syn oligomers but with less toxicity to SH-SY5Y cells, according to MTT and LDH assays. LC-MS analysis identified gallic acid, kaempferol 3-glucoside, kaempferol-3-O-β-rutinoside, and quercetin which were subsequently shown to be strong α-Syn fibrillation inhibitors. Our results highlight the benefits of R. damascena extract to combat PD at the population level.

Abstract
Background Alzheimer's disease (AD) is one of the most common neurodegenerative diseases in the older population and characterized by progressive memory and cognitive impairment. Cyperus rotundus, a traditional medicinal herb, has analgesic, sedative, and anti-inflammatory effects and also used to increase memory in Islamic traditional medicine. This study was designed to consider the effects of C. rotundus extract on memory impairment and neurogenesis in the Beta-Amyloid rats' model. Materials and Methods Forty-two male Wistar rats were randomly divided into six groups (n = 7) for the evaluation of baseline training performance in the Morris water maze test. Then, amyloid-beta (Aβ1-42) was injected in animal hippocampal CA1 bilaterally in four groups. The first probe trial was performed 21 days after Aβ injection. Then, 250, 500, and 750 mg/kg of C. rotundus extract were administered to three Aβ-injected groups for 1 month; after that, the second probe trial was performed, and rats were sacrificed after 28 days of the second probe trial. The neurogenesis was detected in the hippocampus, by immunohistochemical staining. Results This study showed that spatial memory increased in the behavioral test in AD treated group with C. rotundus extract, compared with the AD group (P = 0.02). Immunohistochemical staining revealed that neuronal differentiation has been occurred in the hippocampus in the AD-treated group with C. rotundus extract compared with the AD group (P = 0.01). Conclusions This study showed that C. rotundus extract, repaired spatial memory impairment in the Aβ rats, through increased neurogenesis in the hippocampus, which could be related to the flavonoid components in the extract.
