Zhou X, Zhang Z, Shi H, Liu Q, Chang Y, Feng W, Zhu S, Sun S. Effects of Lycium barbarum glycopeptide on renal and testicular injury induced by di(2-ethylhexyl) phthalate. Cell Stress Chaperones 2022; 27:257-271. [PMID: 35362893 PMCID: PMC9106773 DOI: 10.1007/s12192-022-01266-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2021] [Revised: 02/28/2022] [Accepted: 03/20/2022] [Indexed: 11/28/2022] Open
Abstract
Di(2-ethylhexyl) phthalate (DEHP) is a common environmental pollutant with renal and reproductive toxicity. Lycium barbarum glycopeptide (LbGp) is the main active component of Lycium barbarum, which can protect the kidney and promote reproduction. Autophagy and apoptosis are the regulatory mechanisms of cell adaptation to external stress. This study investigated whether DEHP and LbGp affect kidney and testis by regulating autophagy and apoptosis. DEHP induced apoptosis in human embryonic kidney-293 (HEK-293) cells and human kidney-2 (HK-2) cells, as well as glomerular enlargement, enhanced renal autophagy and inflammation, decreased testicular germ cells, and enhanced testicular autophagy. LbGp reduced apoptosis in HEK-293 cells and HK-2 cells, reduced glomerular enlargement and renal inflammation, enhanced renal autophagy, increased testicular germ cells, and alleviated testicular autophagy. These results suggested that DEHP induced inflammation to cause kidney injury, mildly enhanced renal autophagy, and also induced excessive autophagy, leading to testicular injury. LbGp reduced inflammation and appropriately enhanced autophagy to alleviate renal injury and also reduced excessive autophagy to alleviate testicular injury. Silent information regulator 1 (SIRT1)/forkhead box O3a (FoxO3a)-mediated autophagy and p38 mitogen-activated protein kinase (p38 MAPK)-mediated inflammation played important roles.

Abstract
The term "superfruit" usually refers to certain fruits, which are rich in antioxidant components, therefore, are beneficial to human health. In China, there has been the concept of health preservation and dietary therapy through food intake in a long history. However, some other superfruits growing mainly in China have not attracted extensive attention, such as Cili, Goji berry, and sea buckthorn. Many studies suggested all of these superfruits showed strong antioxidant effects and anti-inflammatory activity in common. However, there are various other advantages and functions in different fruits. This article reviewed the research findings from the existing literature published about major antioxidant bioactive compounds and the potential health benefits of these fruits. The phytochemicals from superfruits are bioaccessible and bioavailable in humans with promising health benefits. More studies are needed to validate the health benefits of these superfruits. It would provide essential information for further research and functional food development.

Tetrahexyldecyl Ascorbate (THDC) Degrades Rapidly under Oxidative Stress but Can Be Stabilized by Acetyl Zingerone to Enhance Collagen Production and Antioxidant Effects. Int J Mol Sci 2021; 22:ijms22168756. [PMID: 34445461 PMCID: PMC8395926 DOI: 10.3390/ijms22168756] [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: 07/13/2021] [Revised: 08/08/2021] [Accepted: 08/09/2021] [Indexed: 11/18/2022] Open
Abstract
Tetrahexyldecyl Ascorbate (THDC) is an L-ascorbic acid precursor with improved stability and ability to penetrate the epidermis. The stability and transdermal penetration of THDC, however, may be compromised by the oxidant-rich environment of human skin. In this study, we show that THDC is a poor antioxidant that degrades rapidly when exposed to singlet oxygen. This degradation, however, was prevented by combination with acetyl zingerone (AZ) as a stabilizing antioxidant. As a standalone ingredient, THDC led to unexpected activation of type I interferon signaling, but this pro-inflammatory effect was blunted in the presence of AZ. Moreover, the combination of THDC and AZ increased expression of genes associated with phospholipid homeostasis and keratinocyte differentiation, along with repression of MMP1 and MMP7 expression, inhibition of MMP enzyme activity, and increased production of collagen proteins by dermal fibroblasts. Lastly, whereas THDC alone reduced viability of keratinocytes exposed to oxidative stress, this effect was completely abrogated by the addition of AZ to THDC. These results show that AZ is an effective antioxidant stabilizer of THDC and that combination of these products may improve ascorbic acid delivery. This provides a step towards reaching the full potential of ascorbate as an active ingredient in topical preparations.

Zeaxanthin-Rich Extract from Superfood Lycium barbarum Selectively Modulates the Cellular Adhesion and MAPK Signaling in Melanoma versus Normal Skin Cells In Vitro. Molecules 2021; 26:molecules26020333.

Abstract
The concern for implementing bioactive nutraceuticals in antioxidant-related therapies is of great importance for skin homeostasis in benign or malignant diseases. In order to elucidate some novel insights of Lycium barbarum (Goji berry) activity on skin cells, the present study focused on its active compound zeaxanthin. By targeting the stemness markers CD44 and CD105, with deep implications in skin oxidative stress mechanisms, we revealed, for the first time, selectivity in zeaxanthin activity. When applied in vitro on BJ human fibroblast cell line versus the A375 malignant melanoma cells, despite the moderate cytotoxicity, the zeaxanthin-rich extracts 1 and 2 were able to downregulate significantly the CD44 and CD105 membrane expression and extracellular secretion in A375, and to upregulate them in BJ cells. At mechanistic level, the present study is the first to demonstrate that the zeaxanthin-rich Goji extracts are able to influence selectively the mitogen-activated protein kinases (MAPK): ERK, JNK and p38 in normal BJ versus tumor-derived A375 skin cells. These results point out towards the applications of zeaxanthin from L. barbarum as a cytoprotective agent in normal skin and raises questions about its use as an antitumor prodrug alone or in combination with standard therapy.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Lycium is widely distributed in the arid to semi-arid environments of North and South America, Africa, and Eurasia. In recent years, Lycium barbarum and L. chinense have been advertised as "superfood" with healthy properties. Despite of its popularity, there is a lack of an integrated and critical appraisal of the existing evidence for the use of Lycium. AIM OF THE STUDY There is a need to understand: 1) Which species were used and how the uses of Lycium developed spatially and over time, 2) how uses differ among regions with different culture backgrounds, and 3) how traditional and current therapeutic and preventive health claims correlate with pharmacological findings. METHODS Information was retrieved from floras, taxonomic, botanical, and ethnobotanical databases, research articles, recent editions of historical Chinese herbals over the last 2000 years, and pharmacopoeias. RESULTS Of totally 97 species, 31 have recorded uses as food and/or medicine worldwide. Usually the fruits are used. While 85% of the Lycium species occur in the Americas and Africa, 26% of them are used, but 9 out of 14 species in Eurasia. In China, seven species and two varieties of the genus Lycium occur, of which four species have been used by different ethnic groups. Only L. barbarum and L. chinense have been transformed into globally traded commodities. In China, based on the name "", their use can be traced back over the last two millennia. Lycium fruits for anti-aging, improving eyesight and nourishment were documented already in 500C.E. (Mingyi Bielu). Recent findings explain the pharmacological foundations of the traditional uses. Especially polysaccharides, zeaxanthin dipalmitate, vitamins, betaine, and mixed extracts were reported to be responsible for anti-aging, improving eyesight, and anti-fatigue effects. CONCLUSIONS The integration of historical, ethnobotanical, botanical, phytochemical and pharmacological data has enabled a detailed understanding of Lycium and its wider potential. It highlights that the focus so far has only been on two species and that the genus can potentially yield a wide range of other products with different properties.

Abstract
Goji bery extracts scavenged at low concentrations free radicals. Extracts protected at low concentrations peroxyl radical-induced DNA damage. Extracts increased GSH levels in C2C12 muscle cells. Extracts decreased lipid peroxidation and protein oxidation in C2C12 muscle cells.
The aim of this study was to assess the antioxidant and antimutagenic activities of ultrasound assisted aqueous extracts from dry goji berry fruits cultivated in Greece. The extracts’ free radical scavenging activity was assessed by the DPPH• and ABTS•+ assays. The results from both assays demonstrated that the extracts exhibited strong radical scavenging activity with IC50 values ranging from 1.29 to 3.00 mg/ml for DPPH• and from 0.39 to 1.10 mg/mL for ABTS•+ assay. The investigated extracts also inhibited free radical-induced DNA damage induced by peroxyl (ROO•) radicals with IC50 ranging from 0.69 to 6.90 mg/mL. Τhe antioxidant activity of the goji berry extract exhibited the highest potency in the above assays was also examined in muscle cells. In particular, muscle C2C12 cells were treated with the selected extract at non cytotoxic concentrations for 24 h and four oxidative stress markers were measured: total reactive oxygen species (ROS), glutathione (GSH), lipid peroxidation and protein carbonyl levels. The results showed that the extract at 25 and 100 μg/mL increased GSH levels up to 189.5% and decreased lipid peroxidation and protein carbonyls by 21.8 and 29.1% respectively. The present study was the first on the antioxidant effects of ultrasound assisted aqueous extracts from goji berry fruits in muscle cells.

Abstract
Diabetic retinopathy is a preventable microvascular diabetic complication and a leading cause of vision loss. Retinal pigment epithelial cell apoptosis is an early event in diabetic retinopathy. Taurine is reportedly beneficial for diabetic retinopathy and is abundant in the fruit of Lycium barbarum (LB). We have investigated the effect of pure taurine and an extract of LB rich in taurine on a model of diabetic retinopathy, the retinal ARPE-19 cell line exposed to high glucose. We demonstrate for the first time that LB extract and the active ligand, taurine, dose dependently enhance cell viability following high glucose treatment in the ARPE-19 retinal epithelial cell line. This cytoprotective effect was associated with the attenuation of high glucose-induced apoptosis, which was shown by characteristic morphological staining and the dose-dependent decrease in the number of apoptotic cells, determined by flow cytometry. Moreover, we have shown that LB extract and taurine dose dependently downregulate caspase-3 protein expression and the enzymatic activity of caspase-3.
We conclude that taurine, a major component of LB, and the LB extract, have a cytoprotective effect against glucose exposure in a human retinal epithelial cell line and may provide useful approaches to delaying diabetic retinopathy progression.

Abstract
BACKGROUND This randomized, double-blind, placebo-controlled clinical trial is the first study reported from outside China that has examined the general effects of the orally consumed goji berry, Lycium barbarum, as a standardized juice (GoChi; FreeLife International LLC, Phoenix, AZ) to healthy adults for 14 days. METHODS Based upon the medicinal properties of Lycium barbarum in traditional Asian medicine, we examined by questionnaire subjective ratings (0-5) of general feelings of well-being, neurologic/psychologic traits, gastrointestinal, musculoskeletal, and cardiovascular complaints as well as any adverse effects. Also, measures of body weight, body-mass index, blood pressure, pulse rate, and visual acuity were assessed before and after consuming 120 mL of GoChi/day or placebo control solution. Data were statistically analyzed for changes between day 1 and day 15. RESULTS Significant differences between day 1 and day 15 were found in the GoChi group (N = 16) in increased ratings for energy level, athletic performance, quality of sleep, ease of awakening, ability to focus on activities, mental acuity, calmness, and feelings of health, contentment, and happiness. GoChi also significantly reduced fatigue and stress, and improved regularity of gastrointestinal function. In contrast, the placebo group (N = 18) showed only two significant changes (heartburn and happiness). No significant changes in musculoskeletal or cardiovascular complaints were observed in either group. All parametric data (body weight, etc.) were not significantly different between groups or between day 1 and day 15 for either group. CONCLUSIONS These results clearly indicate that daily consumption of GoChi for 14 days increases subjective feelings of general well-being, and improves neurologic/psychologic performance and gastrointestinal functions. The data strongly suggest that further research is indicated to confirm and extend knowledge of the potential effects of Lycium barbarum upon human health.

Abstract
Lycium barbarum (Gouqizi, Fructus Lycii, Wolfberry) is well known for nourishing the liver, and in turn, improving the eyesight. However, many people have forgotten its anti-aging properties. Valuable components of L. barbarum are not limited to its colored components containing zeaxanthin and carotene, but include the polysaccharides and small molecules such as betaine, cerebroside, beta-sitosterol, p-coumaric, and various vitamins. Despite the fact that L. barbarum has been used for centuries, its beneficial effects to our bodies have not been comprehensively studied with modern technology to unravel its therapeutic effects at the biochemical level. Recently, our laboratory has demonstrated its neuroprotective effects to counter neuronal loss in neurodegenerative diseases. Polysaccharides extracted from L. barbarum can protect neurons against beta-amyloid peptide toxicity in neuronal cell cultures, and retinal ganglion cells in an experimental model of glaucoma. We have even isolated the active component of polysaccharide which can attenuate stress kinases and pro-apoptotic signaling pathways. We have accumulated scientific evidence for its anti-aging effects that should be highlighted for modern preventive medicine. This review is to provide background information and a new direction of study for the anti-aging properties of L. barbarum. We hope that new findings for L. barbarum will pave a new avenue for the use of Chinese medicine in modern evidence-based medicine.

Abstract
In search of novel angiostimulators, we performed a high-throughput screening of medicinal plants beneficial for blood circulation. From the panel of positive hits, Angelica sinensis was selected for further investigation. Purified down to a low-molecular-weight fraction and characterized by high-performance liquid chromatography-mass spectrometry, the material, named SBD.4A, revealed a particularly strong wound healing activity in the diabetic mouse wound-healing model, and in the human/severe combined immunodeficiency mouse chimera wound-healing model. In both models, SBD.4A compared favorably with the Food and Drug Administration-approved wound-healing drug becaplermin, suggesting that this botanical product could be a valuable treatment for difficult-to-heal wounds. Further high-performance liquid chromatography fractionation of SBD.4A yielded a hydrophilic fraction, which strongly stimulated endothelial cell proliferation, tridimensional endothelial cell network formation, as well as the proliferation of human dermal fibroblasts and type I collagen secretion. Because angiogenesis and fibroblast proliferation are essential for wound healing, we propose that this liquid chromatography-mass spectrometry-defined hydrophilic fraction is at least partially responsible for the wound-healing activity of SBD.4A.
