Abstract
Aging and stress have contributed to the development of memory disorders. Phe-Pro-Phe (FPF) was identified with high stability by mass spectrometry from simulated gastrointestinal digestion and everted gut sac products of the Antarctic krill peptide Ser-Ser-Asp-Ala-Phe-Phe-Pro-Phe-Arg (SSDAFFPFR) which was found to have a positive impact on memory enhancement. This study investigated the digestive stability, absorption, and memory-enhancing effects of FPF using nuclear magnetic resonance spectroscopy, simulated gastrointestinal digestion, in vivo fluorescence distribution analysis, mouse behavioral experiments, acetylcholine function, Nissl staining, immunofluorescence, and immunohistochemistry. FPF crossed the blood-brain barrier into the brain after digestion, significantly reduced shock time, working memory errors, and reference memory errors, and increased the recognition index. Additionally, FPF elevated ACh content; Nissl body counts; and CREB, SYN, and PSD-95 expression levels, while reducing AChE activity (P < 0.05). This implies that FPF prevents scopolamine-induced memory impairment and provides a basis for future research on memory disorders.

Younis NS. Myrrh Essential Oil Mitigates Renal Ischemia/Reperfusion-Induced Injury. Curr Issues Mol Biol 2023; 45:1183-1196. [PMID: 36826023 PMCID: PMC9955815 DOI: 10.3390/cimb45020078] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 01/16/2023] [Accepted: 01/24/2023] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Ischemia/reperfusion (I/R)-induced renal injury is a common reason for kidney injury in clinical settings; therefore, continuous investigation of novel nephroprotective agents is crucial. Myrrh, the oleoresin exudates generated by the genus Commiphora, display numerous pharmacological actions. This study tried to assess the preventive effects of myrrh essential oil against I/R-induced renal damage. METHODS Rats were randomized into five groups. In the sham group, the animals were subjected to bilateral renal artery separation with no occlusion. In the sham + myrrh group; the rats were administered myrrh essential oil and then treated similarly to the sham group. Renal I/R group: the animals were challenged with renal I/R. In the myrrh + renal I/R groups, rats were administered 50 or 100 mg/kg of myrrh essential oil orally for three weeks before being confronted with I/R. RESULTS Serum levels of renal function tests and renal injury biomarkers, including NGAL, KIM-1, and CysC, were amplified in the renal I/R group. Animals that experienced renal I/R exhibited elevated lipid peroxidation (MDA); declined SOD, CAT, and GPx activity; declined GSH content; augmented TLR4/NFκB gene expression; and subsequent enhancement of inflammatory mediators (TNF-α, IFN-γ, IL-1β, and IL-6). Myrrh reduced renal function tests and injury biomarkers and amended renal histological alterations. Pretreatment with myrrh reduced MDA, elevated the antioxidant enzymes' activities and GSH content, and reduced the TLR4 and NFκB gene expression, leading to subsequent inflammation and apoptosis alleviation. CONCLUSIONS The outcomes of the present investigation established the protective effect of myrrh essential oil against renal I/R via pointing out the antioxidant, anti-inflammatory, and anti-apoptotic effects of myrrh.

Abstract
Parkia roxburghii belongs to the family Mimosaceae; it has been used since ancient times as a cure for different health complications; such as inflammatory and gynecological diseases and hemiplegia. In this investigation, a reversed-phase-high-performance liquid chromatography (RP-HPLC) profile was carried out for P. roxburghii; also, the isolated bioactive compounds including quercetin, catechin, and biochaninA were individually and/or in combination investigated for their inhibitory effects on scopolamine-induced memory impairments in mice, implying that they have the ability to reduce the neurodegenerative effects of scopolamine and thus could be employed as a more effective therapeutic agent in the treatment of Alzheimer's disease (AD) in humans. The possible interactions of Parkia flavonoids with acetylcholinesterase (AChE), γ-aminobutyric acid A receptor, alpha5 (GABAA α5), glycogen synthase kinase-3 (GSK-3), p38 mitogen-activated protein kinase (p38MAP-kinase), signal-regulated kinase (ERK), and protein-serine/threonine kinase (Akt) were then determined using molecular docking.

Abstract
BACKGROUND Frankincense and myrrh are used as traditional anti-inflammatory and analgesic medicines in China. It has been reported that frankincense and myrrh have significant anti-tumor activities. The present study was designed to investigate the inhibitory efficacy of frankincense ethanol extracts (RXC), myrrh ethanol extracts (MYC), frankincense -myrrh ethanol extracts (YDC), frankincense -myrrh water extracts (YDS) and their main compounds on U266 human multiple myeloma cell line. METHODS The inhibition effects of cell proliferation was evaluated by MTT assays. Cell culture supernatant was collected for estimation of cytokines. Western blot analysis was designed to investigate the regulatory of JAK/STAT signal pathway. In addition, cell metabolomics based on the ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC/Q-TOF-MS) had been established to investigate the holistic efficacy of frankincense and myrrh on U266 cells. Acquired data were processed by partial least-squares discriminant analysis (PLS-DA) and orthogonal projection to latent structures squares-discriminant analysis (OPLS-DA) to identify potential biomarkers. RESULTS RXC, MYC significantly inhibited the proliferation of U266 cells at dose of 25-400 μg/mL, YDC and YDS at the dose of 12.5-400 μg/mL. 3-O-acetyl-α-boswellic acid, 3-acetyl-11 keto-boswellic acid and 11-keto-boswellic acid had the most significant anti- multiple myeloma activities in the 10 compounds investigated, therefore these 3 compounds were selected as representatives for Elisa assay and western blotting experiments. All the extracts and active compounds ameliorated the secretion of cytokines and down-regulated the expression of JAK/STAT signaling pathway-related proteins. Comparing RXC, MYC, YDC and YDS-treated U266 cells with vehicle control (DMSO), 13, 8, 7, 7 distinct metabolites and 2, 2, 3, 0 metabolic target pathways involved in amino acid metabolism, lipid metabolism, vitamin metabolism, arachidonic acid were identified, respectively. CONCLUSIONS Taken together our results suggest that the frankincense and myrrh and their bioactive compounds inhibit proliferation of U266 multiple myeloma cells by regulating JAK/STAT signaling pathway and cellular metabolic profile.

Genistein Ameliorates Scopolamine-Induced Amnesia in Mice Through the Regulation of the Cholinergic Neurotransmission, Antioxidant System and the ERK/CREB/BDNF Signaling. Front Pharmacol 2018; 9:1153. [PMID: 30369882 PMCID: PMC6194227 DOI: 10.3389/fphar.2018.01153] [Citation(s) in RCA: 54] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2018] [Accepted: 09/24/2018] [Indexed: 01/16/2023] Open
Abstract
Genistein (GE) was reported to exert a wide spectrum of biological activities, including antioxidant, anti-inflammatory, anti-mutagenic, anticancer, and cardio-protective effects. In addition, both clinical and preclinical studies have recently suggested GE a potential neuroprotective and memory-enhancing drug against neurodegenerative diseases. The animal model of scopolamine (Scop)-induced amnesia is widely used to study underlying mechanisms and treatment of cognitive impairment in neurodegenerative diseases. However, there is no report about the effects of GE on Scop-induced amnesia in mice. Therefore, the present study was carried out to investigate the beneficial effects and potential mechanism of GE against Scop-induced deficits in mice. The mice were orally pretreated with either GE (10, 20, and 40 mg/kg) or donepezil (1.60 mg/kg) for 14 days. After the pretreatment, the open field test was conducted to assess the effect of GE on the locomotor activity of mice. Thereafter, mice were daily injected with Scop (0.75 mg/kg) intraperitoneally to induce memory deficits and subjected to the cognitive behavioral tests including the Object Location Recognition (OLR) experiment and Morris Water Maze (MWM) task. After the behavioral tests, biochemical parameter assay and western blot analysis were used to examine the underlying mechanisms of its action. The results showed that GE administration significantly improved the cognitive performance of Scop-treated mice in OLR and Morris water maze tests, exerting the memory-enhancing effects. Additionally, GE remarkably promoted the cholinergic neurotransmission and protected against the oxidative stress damage in the hippocampus of Scop-treated mice, as indicated by decreasing AChE activity, elevating ChAT activity and Ach level, increasing SOD activity, lowering the level of MDA and increasing GSH content. Furthermore, GE was found to significantly upregulate the expression levels of p-ERK, p-CREB and BDNF proteins in the hippocampus of Scop-treated mice. Taken together, these results for the first time found that GE exerts cognitive-improving effects in Scop-induced amnesia and suggested it may be a potential candidate compound for the treatment of some neurodegenerative diseases such as Alzheimer's Disease (AD).

Abstract
BACKGROUND Grapes are among the most widely consumed plants and are used as a folk medicine. Vitis species have been traditionally used as anti-inflammatory, analgesic, and memory-enhancing agents, but, their biological activities of discarded grape leaves are not completely understood. PURPOSE We investigated the effects of alcoholic aqueous leaf extract of Vitis labruscana (LEVL) in a mouse model of memory impairment and tried to ascertain its mechanism. We also evaluated its effects in SH-SY5Y cells. METHODS LEVL (50, 100, and 150 mg/kg) was administered to ICR mice once daily for 7 days. Memory impairment was induced with intraperitoneal scopolamine injections (1 mg/kg) and measured with the Y-maze test and a passive avoidance task. LEVL-induced signaling was evaluated in SH-SY5Y cells and mouse hippocampi. RESULTS We first identified quercetin-3-O-glucuronide as LEVL's major component. We then showed that LEVL promoted phosphorylation of Akt, extracellular regulated kinase (ERK), and cyclic AMP response element binding protein (CREB) and proliferation of SH-SY5Y cells. Oral LEVL administration (100 mg/kg) for 7 days significantly reversed scopolamine-induced reductions of spontaneous alternation in the Y-maze test and scopolamine-induced shortening of latency times in the passive avoidance task's retention trial. Consistent with the cell experiment results, LEVL restored scopolamine-decreased phosphorylation of Akt, ERK, and CREB and scopolamine-reduced expression of brain-derived neuroprotective factor expression in mouse hippocampi. CONCLUSION Our results suggest that LEVL promotes phosphorylation of Akt, ERK, and CREB in the hippocampus and ameliorates scopolamine-induced memory impairment in mice.

Abstract
CONTEXT Anxiety and depression are common in Alzheimer's disease (AD). Despite some evidence, it is difficult to confirm Lavandula officinalis Chaix ex Vill (Lamiaceae) as an anxiolytic and antidepressant drug. OBJECTIVE The effects of L. officinalis extract were studied in scopolamine-induced memory impairment, anxiety and depression-like behaviour. MATERIALS AND METHODS Male NMRI rats were divided into control, scopolamine alone-treated group received scopolamine (0.1 mg/kg) intraperitoneally (i.p.), daily and 30 min prior to performing behavioural testing on test day, for 12 continuous days and extract pretreated groups received aerial parts hydro alcoholic extract (i.p.) (100, 200 and 400 mg/kg), 30 min before each scopolamine injection. Memory impairment was assessed by Y-maze task, while, elevated plus maze and forced swimming test were used to measure anxiolytic and antidepressive-like activity. RESULTS Spontaneous alternation percentage in Y maze is reduced by scopolamine (36.42 ± 2.60) (p ≤ 0.001), whereas lavender (200 and 400 mg/kg) enhanced it (83.12 ± 5.20 and 95 ± 11.08, respectively) (p ≤ 0.05). Also, lavender pretreatment in 200 and 400 mg/kg enhanced time spent on the open arms (15.4 ± 3.37 and 32.1 ± 3.46, respectively) (p ≤ 0.001). On the contrary, while immobility time was enhanced by scopolamine (296 ± 4.70), 100, 200 and 400 mg/kg lavender reduced it (193.88 ± 22.42, 73.3 ± 8.25 and 35.2 ± 4.22, respectively) in a dose-dependent manner (p ≤ 0.001). DISCUSSION AND CONCLUSION Lavender extracts improved scopolamine-induced memory impairment and also reduced anxiety and depression-like behaviour in a dose-dependent manner.
