Abstract
Major depressive disorder (MDD) is a multimodal neuropsychiatric and neurodegenerative illness characterized by anhedonia, continued melancholy, dysfunctional circadian rhythm and many other behavioral infirmities. Depression is also associated with somatic ailments such as cardiometabolic diseases. The existing and upcoming hypotheses have succeeded in explaining the pathophysiology of depression. Only a few of the most validated theories, such as hyperactivity of the HPA axis, activated inflammatory-immune response, and monoaminergic and GABAergic deficit hypotheses, have been discussed in this review. So, an effective and safer alternative approach beyond symptomatic relief has been desired. Therefore, botanical products have steadily been probed to strengthen the modern medicinal system as a promising medicament. In this line, Asparagus racemosus Willd. belongs to Asparagaceace family is the well-documented adaptogen cited in the ancient texts namely, Ayurvedic, Greek, and Chinese medicine system. The whole plant possesses pleiotropic therapeutic activity, antioxidant, anti-inflammatory, immunomodulatory, neuroprotective, nootropic, antidepressant, etc., without showing any remarkable side effects. The literature review has also suggested that A. racemosus administration at varied levels alleviates depression by modulating the HPA axis, increasing BDNF levels, and monoaminergic and GABAergic neurotransmission. Alongside, spikes the level of antioxidant enzymes, SOD, GSH peroxidase, GSH, and catalase in distinct brain regions (i.e., hippocampus, prefrontal cortex, amygdala, and hypothalamus) and promote neurogenesis and neuroplasticity. Thus, it could be a new generation antidepressant that provides relief from both behavioral and somatic illness. The review first describes the plant characteristics, then discusses the hypotheses associated with the pathogenesis of depression, and gives an insight into A. racemosus antidepressant properties and the underlying mechanism.

The Combination of AHCC and ETAS Decreases Migration of Colorectal Cancer Cells, and Reduces the Expression of LGR5 and Notch1 Genes in Cancer Stem Cells: A Novel Potential Approach for Integrative Medicine. Pharmaceuticals (Basel) 2021; 14:ph14121325. [PMID: 34959725 PMCID: PMC8705140 DOI: 10.3390/ph14121325] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2021] [Accepted: 12/11/2021] [Indexed: 11/18/2022] Open
Abstract
The AHCC standardized extract of cultured Lentinula edodes mycelia, and the standardized extract of Asparagus officinalis stem, trademarked as ETAS, are well known supplements with immunomodulatory and anticancer potential. Several reports have described their therapeutic effects, including antioxidant and anticancer activity and improvement of immune response. In this study we aimed at investigating the effects of a combination of AHCC and ETAS on colorectal cancer cells and biopsies from healthy donors to assess the possible use in patients with colorectal cancer. Our results showed that the combination of AHCC and ETAS was synergistic in inducing a significant decrease in cancer cell growth, compared with single agents. Moreover, the combined treatment induced a significant increase in apoptosis, sparing colonocytes from healthy donors, and was able to induce a strong reduction in migration potential, accompanied by a significant modulation of proteins involved in invasiveness. Finally, combined treatment was able to significantly downregulate LGR5 and Notch1 in SW620 cancer stem cell (CSC) colonospheres. Overall, these findings support the potential therapeutic benefits of the AHCC and ETAS combinatorial treatment for patients with colorectal cancer.

Standardized Extract of Asparagus officinalis Stem Attenuates SARS-CoV-2 Spike Protein-Induced IL-6 and IL-1β Production by Suppressing p44/42 MAPK and Akt Phosphorylation in Murine Primary Macrophages. Molecules 2021; 26:molecules26206189. [PMID: 34684771 PMCID: PMC8540605 DOI: 10.3390/molecules26206189] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 10/07/2021] [Accepted: 10/12/2021] [Indexed: 01/10/2023] Open
Abstract
Excessive host inflammation following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is associated with severity and mortality in coronavirus disease 2019 (COVID-19). We recently reported that the SARS-CoV-2 spike protein S1 subunit (S1) induces pro-inflammatory responses by activating toll-like receptor 4 (TLR4) signaling in macrophages. A standardized extract of Asparagus officinalis stem (EAS) is a unique functional food that elicits anti-photoaging effects by suppressing pro-inflammatory signaling in hydrogen peroxide and ultraviolet B-exposed skin fibroblasts. To elucidate its potential in preventing excessive inflammation in COVID-19, we examined the effects of EAS on pro-inflammatory responses in S1-stimulated macrophages. Murine peritoneal exudate macrophages were co-treated with EAS and S1. Concentrations and mRNA levels of pro-inflammatory cytokines were assessed using enzyme-linked immunosorbent assay and reverse transcription and real-time polymerase chain reaction, respectively. Expression and phosphorylation levels of signaling proteins were analyzed using western blotting and fluorescence immunomicroscopy. EAS significantly attenuated S1-induced secretion of interleukin (IL)-6 in a concentration-dependent manner without reducing cell viability. EAS also markedly suppressed the S1-induced transcription of IL-6 and IL-1β. However, among the TLR4 signaling proteins, EAS did not affect the degradation of inhibitor κBα, nuclear translocation of nuclear factor-κB p65 subunit, and phosphorylation of c-Jun N-terminal kinase p54 subunit after S1 exposure. In contrast, EAS significantly suppressed S1-induced phosphorylation of p44/42 mitogen-activated protein kinase (MAPK) and Akt. Attenuation of S1-induced transcription of IL-6 and IL-1β by the MAPK kinase inhibitor U0126 was greater than that by the Akt inhibitor perifosine, and the effects were potentiated by simultaneous treatment with both inhibitors. These results suggest that EAS attenuates S1-induced IL-6 and IL-1β production by suppressing p44/42 MAPK and Akt signaling in macrophages. Therefore, EAS may be beneficial in regulating excessive inflammation in patients with COVID-19.

Neuroprotective Effects of Asparagus officinalis Stem Extract in Transgenic Mice Overexpressing Amyloid Precursor Protein. J Immunol Res 2021; 2021:8121407. [PMID: 34046506 PMCID: PMC8128539 DOI: 10.1155/2021/8121407] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2020] [Revised: 01/25/2021] [Accepted: 04/30/2021] [Indexed: 12/11/2022] Open
Abstract
To mimic Alzheimer's disease, transgenic mice overexpressing the amyloid precursor protein (APP) were used in this study. We hypothesize that the neuroprotective effects of ETAS®50, a standardized extract of Asparagus officinalis stem produced by Amino Up Co., Ltd. (Sapporo, Japan), are linked to the inhibition of the apoptosis cascade through an enhancement of the stress-response proteins: heat shock proteins (HSPs). APP-overexpressing mice (double-transgenic APP and PS1 mouse strains with a 129s6 background), ages 6-8 weeks old, and weighing 20-24 grams were successfully bred in our laboratory. The animals were divided into 5 groups. APP-overexpressing mice and wild-type (WT) mice were pretreated with ETAS®50 powder (50% elemental ETAS and 50% destrin) at 200 mg/kg and 1000 mg/kg body weight. Saline, the vehicle for ETAS®50, was administered in APP-overexpressing mice and WT mice. ETAS®50 and saline were administered by gavage daily for 1 month. Cognitive assessments, using the Morris Water Maze, demonstrated that memory was recovered following ETAS®50 treatment as compared to nontreated APP mice. At euthanization, the brain was removed and HSPs, amyloid β, tau proteins, and caspase-3 were evaluated through immunofluorescence staining with the appropriate antibodies. Our data indicate that APP mice have cognitive impairment along with elevated amyloid β, tau proteins, and caspase-3. ETAS®50 restored cognitive function in these transgenic mice, increased both HSP70 and HSP27, and attenuated pathogenic level of amyloid β, tau proteins, and caspsase-3 leading to neuroprotection. Our results were confirmed with a significant increase in HSP70 gene expression in the hippocampus.

Abstract
Debilitating neuropsychiatric and neurodegenerative conditions are associated with complex multifactorial pathophysiology. Their treatment strategies often only provide symptomatic relief, delaying disease progression without giving a complete cure. Potent and safer treatment alternatives beyond symptomatic relief are sought. Herbal supplements have surely been explored due to their multiple component nature to enhance the effect of western medications. One such well-documented nutraceutical in the ancient Greek, Chinese, and Ayurvedic medicine system known for its various medicinal benefits is Asparagus racemosus. Widely used for its lactogenic properties, A. racemosus is also cited in Ayurveda as a nervine tonic. A. racemosus based nutraceuticals have shown to possess adaptogenic, neuroprotective, antioxidant, anti-inflammatory, and nootropic activity under preclinical and clinical settings without posing significant adverse effects. A. racemosus extracts restore the perturbed neurotransmitters and prevent oxidative neuronal damage. From the available neuropharmacological researches, the physiological actions of A. racemosus can ultimately be directed for either augmentation of cognitive ability or in the management of neurological conditions such as stress, anxiety, depression, epilepsy, Parkinson's, and Alzheimer's disease. The studies focus on the multi-component extract, and the lack of standardization has been a major hurdle in preventing the allotment of reported neuropharmacological activity to one of the phytoconstituent. Herbal standardization of the plant extract based on a specific biomarker can help elucidate the intricate biomolecular pathway and neurocircuitries being involved. This, followed by rigorous standardized clinical trials, fixing dosages, and determining contraindications would facilitate the translation of A. racemosus to a FDA-approved neuromedicine for neurological disorders.

Abstract
Asparagus africanus Lam. is a plant used traditionally to treat different ailments. Currently, scanty information is available on its safety. The aim of this study is to determine the acute toxicity of the methanolic extract on vital organs and its associated biochemical parameters. Fifteen female Sprague-Dawley rats were divided into five groups. Group I served as normal control, groups II, III, IV, and V were orally administered single dose of crude extract dissolved in distilled water at 5 mg/kg BW, 50 mg/kg BW, 300 mg/kg BW and 2,000 mg/kg BW. Rats were observed for 14 days and body weights were recorded. On day 15, the rats were sacrificed and blood samples were collected for biochemical and haematological analyses, while the liver and kidneys were sampled for histopathological examination. Body weight and haematology parameters results showed significance difference (p < 0.05) among means of HGB, RDW, RBC, and MCHC; likewise, (p < 0.001) for WBC and platelet among treated groups. Histopathology result showed that kidneys appeared normal while livers were congested with mildly swollen hepatocytes and occasional binucleation. Focal lobular hepatitis was observed in all treated animals. However, hepatic enzymes were not significantly affected and no histopathological harmful effects were observed in kidney. In conclusion, methanolic extracts of A. africanus are safe up to 2,000 mg/kg BW. The obtained results could be used as a justification for the traditional application of the plant for treatment of various ailments.

Abstract
ETHNOPHARMACOLOGY RELEVANCE Dendropanax morbifera Leveille (DM) has been used in traditional medicines for infectious and skin diseases, and dysmenorrhea. It exhibits a diverse therapeutic potential including anti-cancer, anti-thrombotic, anti-diabetic, anti-oxidant, and anti-inflammatory activities. AIM OF THE STUDY Despite promising health benefits of DM, knowledge of its potential adverse effects is very limited. The current study focused on the investigation of subchronic toxicity and genotoxicity of extract obtained from DM according to the test guidelines published by the Organization for Economic Cooperation and Development. MATERIALS AND METHODS We conducted a toxicological evaluation of DM extracts using 14-day repeated-dose toxicity study and 13-week repeated-dose toxicity study in Sprague-Dawley rats administered orally at doses of 500, 1000, or 2000 mg/kg/day. The clastogenicity of DM extract was also evaluated by in vitro chromosome aberration assay and in vivo micronucleus assay. RESULTS Assessment of subchronic toxicity of DM extract by oral administration in rats revealed unremarkable treatment-related findings with respect to food/water consumption, body weight, mortality, urinalysis, hematology, serum biochemistry, necropsy, organ weight and histopathology at doses of 500, 1000, and 2000 mg/kg. Accordingly, the level of no-observed-adverse-effect for DM extract in 13-week subchronic toxicity study was considered to be 2000 mg/kg/day in rats. The data observed from in vitro chromosome aberration assay and in vivo micronucleus assay exclude any clastogenicity of DM extract. CONCLUSION The results suggest that the oral consumption of DM extract has no adverse effects in humans and represents a safe traditional medicine.

Abstract
We recently reported that ETAS 50, a standardized extract from the Asparagus officinalis stem, exerted anti-inflammatory effects on ultraviolet-B- (UV-B-) irradiated normal human dermal fibroblasts (NHDFs) by inhibiting nuclear factor-κB p65 nuclear import and the resulting interleukin-1β (IL-1β) expression. To further elucidate the antiphotoaging potency of ETAS 50, we examined the anti-inflammatory effects on UV-B-irradiated NHDFs by focusing on the stress-activated mitogen-activated protein kinase (MAPK) and Akt signaling pathways. NHDFs were treated with 1 mg/mL of ETAS 50 or dextrin (vehicle control) after UV-B irradiation (20 mJ/cm2) for different time periods. Phosphorylation levels of c-Jun N-terminal kinase (JNK), p38 MAPK, and Akt were analyzed by western blotting. IL-6 mRNA levels were analyzed by real-time polymerase chain reaction. UV-B-irradiated NHDFs showed increased phosphorylation levels of JNK, p38 MAPK, and Akt, as well as increased mRNA levels of IL-6. ETAS 50 treatment after UV-B irradiation suppressed the increased phosphorylation levels of Akt without affecting those of JNK and p38 MAPK. ETAS 50 as well as Akt inhibitor Perifosine repressed UV-B irradiation-induced IL-6 mRNA expression. These results suggest that ETAS 50 treatment represses UV-B irradiation-induced IL-6 expression by suppressing Akt phosphorylation. The present findings demonstrate the potential of ETAS 50 to prevent photoaging by attenuating UV-B irradiation-induced proinflammatory responses in skin fibroblasts.

Abstract
Artemisia capillaris (AC) has been used as an alternative therapy in obesity, atopic dermatitis, and liver diseases through several biological activity including anti-steatotic, antioxidant, and anti-inflammatory activities. Despite its ethnomedicinal benefits, no sufficient background information is available about the long-term safety and genotoxicity of the AC extract. Therefore, the present study was carried out to investigate the 13-week subchronic toxicity and genotoxicity of the AC extract according to the test guidelines published by the Organization for Economic Cooperation and Development. In the 13-week toxicity study using doses of 25, 74, 222, 667, and 2000 mg/kg body weight, oral administration of the AC extract in male and female rats did not result in any significant adverse effects in food/water consumption, body weight, mortality, hematology, serum biochemistry, organ weight and histopathology. Accordingly, the no-observed-adverse-effect level in rats of both genders was established for the AC extract at 2000 mg/kg/day, the highest dose level tested. In addition, the AC extract was not genotoxic in a battery of tests including Ames test, in vitro chromosome aberration assay and in vivo micronucleus assay. In conclusion, we demonstrated that the AC extract is considered as a safe traditional medicine for human consumption.

Abstract
The biological fermentation of plants is usually used to improve their product properties, including their biological activity. Acanthopanax koreanum is a plant indigenous to Jeju, Korea; however, fermented A. koreanum (FAK) has not been guaranteed to be safe. Therefore, in this study, a safety evaluation of aqueous extracts of FAK was performed using Sprague Dawley rats. The acute toxicity of FAK did not influence animal mortality, body weight changes or the animals' clinical appearance at a concentration of 5000 mg/kg body weight. Using doses of 500, 1000 and 2000 mg/kg/day in a subchronic (13-week) toxicity study, the administration of FAK in male rats increased their body weight, food consumption, absolute liver weight, liver-associated enzymes and total cholesterol content. However, these effects of FAK were not considered toxic because the changes were not accompanied by any evidence of clinical signs or any change in the histopathological examination. On the other hand, the FAK-treated female rats did not exhibit significant changes in their body weight, food consumption, absolute and relative organ weights or liver enzymes. These results suggest that the acute oral administration of FAK is non-toxic to rats, and 13 weeks of repeated dosing demonstrated no FAK-related toxicity at a concentration of 2000 mg/kg. Therefore, the no-observed-adverse-effect level (NOAEL) of FAK was determined to be 2000 mg/kg/day for both male and female rats.

Abstract
Enzyme-treated asparagus extract (ETAS) has been developed as a novel anti-stress functional food ingredient that is produced from asparagus. Two human intervention trials with ETAS were conducted in healthy adult male volunteers. Study 1 was a randomized, double-blind, placebo-controlled study to assess the effects of ETAS on expression of heat shock protein 70 (HSP70) mRNA in blood and the autonomic nervous system (ANS). The ETAS group showed a tendency to enhance HSP70 mRNA expression level compared to the placebo group. Several ANS condition parameters were significantly improved in the ETAS group when compared to the placebo group. In Study 2, a randomized, double-blind, placebo-controlled, crossover trial investigated the influence on stress-related hormones and sleep. Serum and salivary cortisol levels were significantly elevated compared to baseline during the placebo period, but remained unchanged during the ETAS period. The salivary chromogranin A level was significantly decreased in the ETAS-treated subjects compared to their baseline levels. The actual sleep time was not significantly different between ETAS and placebo. However, when the subjects were divided into two categories based on sleep efficiency or the average of night sleeping time, ETAS intake was effective to modulate the sleep state among those with low sleep efficiency or excess sleep time.

Abstract
Codonopsis lanceolata is a perennial plant that has been used as a food and in traditional medicine for the treatment of cough, bronchitis, and inflammation in East Asia including Korea, Japan, and China. However, information regarding its toxicity is limited. Therefore, we performed a safety evaluation of aqueous C. lanceolata root extract (CLE) in Sprague-Dawley rats. Assessment of acute toxicity revealed that CLE did not influence mortality, clinical appearance, body weight gain, or necropsy findings at a dose of 5000 mg/kg body weight. In the subchronic oral toxicity, data revealed that several significant alteration in food consumption, water consumption, protein excretion, WBCs levels, TGs, BUN levels, and the absolute and relative weights in the liver, spleen and lungs. However, these changes were transient and were not considered treatment related because they showed no apparent dose dependent. These results suggest that CLE (1250, 2500, and 5000 mg/kg body weight/day) administered orally does not cause acute or subchronic toxicity to male or female rats. The 50% lethal dose (LD50) of CLE was determined to be greater than 5000 mg/kg.
