Grape Pomace Polyphenols Reduce Acute Inflammatory Response Induced by Carrageenan in a Murine Model. Chem Biodivers 2024; 21:e202302065.

Abstract
Grape pomace (GP), a by-product of wine production, contains bioactive polyphenols with potential health benefits. This study investigates the anti-inflammatory properties of a polyphenolic fraction derived from GP, obtained by ultrasound-microwave hybrid extraction and purified using ion-exchange chromatography. In the inflammation model, mice were divided into six groups: intact, carrageenan, indomethacin, and three GP polyphenols treatment groups. Paw edema was induced by subplantar injection of carrageenan, and the GP polyphenols were administered intraperitoneally at doses of 10, 20, and 40 mg/kg. The anti-inflammatory effect was evaluated by measuring paw volume, and expression of inflammatory markers: cyclooxygenase-2 (COX-2), myeloperoxidase (MPO), and cytokines (IL-1β and IL-6), along with lipid peroxidation levels. The GP polyphenols significantly reduced paw edema and expression levels of COX-2, MPO, and cytokines in a dose-dependent manner effect, with the highest dose showing the greatest reduction. Additionally, lipid peroxidation levels were also decreased by GP polyphenols treatment at doses of 10 and 20 mg/kg. These findings suggest that ultrasound-microwave extraction combined with amberlite purification proved to be effective in obtaining a polyphenolic-rich fraction from GP. Thus, GP polyphenols may serve as a natural anti-inflammatory and antioxidant agent for treating inflammation and oxidative stress-related diseases.

[PMID: 38555717 DOI: 10.1016/j.knee.2024.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Revised: 02/06/2024] [Accepted: 03/12/2024] [Indexed: 04/02/2024]
Abstract
OBJECTIVE To investigate the effects of astaxanthin (AST) on mouse osteoarthritis (OA) and lipopolysaccharide (LPS)-induced ATDC5 cell damage and to explore whether SIRT1 protein plays a role. METHODS In this study, some mouse OA models were constructed by anterior cruciate ligament transection (ACLT). Imaging, molecular biology and histopathology methods were used to study the effect of AST administration on traumatic OA in mice. In addition, LPS was used to stimulate ATDC5 cells to mimic the inflammatory response of OA. The effects of AST on the cell activity, inflammatory cytokines, matrix metalloproteinases and collagen type II levels were studied by CCK8 activity assay, reverse transcription polymerase chain reaction and protein imprinting. The role of SIRT1 protein was also detected. RESULTS In the mouse OA model, the articular surface collapsed, the articular cartilage thickness and cartilage matrix protein abundance were significantly decreased, while the expression of inflammatory cytokines and matrix metalloproteinases was increased; but AST treatment reversed these effects. Meanwhile, AST pretreatment could partially reverse LPS-induced ATDC5 cell damage and upregulate SIRT1 expression, but this protective effect of AST was attenuated by concurrent administration of the SIRT1 inhibitor Ex527. CONCLUSION AST can protect against the early stages of OA by affecting SIRT1 signalling, suggesting that AST might be a potential therapeutic agent for OA treatment.

Biomedicines 2022; 10:biomedicines10061413. [PMID: 35740434 PMCID: PMC9219661 DOI: 10.3390/biomedicines10061413] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Revised: 06/11/2022] [Accepted: 06/13/2022] [Indexed: 01/05/2023] Open
Abstract
Neuropathic pain is often closely associated with nerve injury or inflammation, and the role of traditional nonsteroidal anti-inflammatory drugs as adjuvants for treating chemotherapy-induced peripheral neuropathic pain remains unclear. In this study, the potential synergistic antinociceptive effects of indomethacin–pregabalin and meloxicam–pregabalin were evaluated in paclitaxel-induced neuropathic pain and carrageenan-induced inflammatory pain in rodents. Although indomethacin and meloxicam alone only slightly relieved mechanical allodynia in the above two models, isobolographic analysis showed that the combination of indomethacin or meloxicam with pregabalin produced significant synergistic antinociceptive effects for paclitaxel-induced neuropathic pain (IN-PGB, experimental ED25 = [4.41 (3.13–5.82)] mg/kg, theoretical ED25 = [8.50 (6.62–10.32)] mg/kg; MEL-PGB, experimental ED25 = [3.96 (2.62–5.46)] mg/kg, theoretical ED25 = [7.52 (5.73–9.39)] mg/kg). In addition, MEL-PGB dosed via intraplantar injection into the left paw, intragastric injection, or intraperitoneal injection reversed paclitaxel-induced allodynia, indicating that they may act at multiple sites in the neuroaxis and periphery. However, indomethacin–pregabalin and meloxicam–pregabalin exerted antagonistic antiallodynic interactions in carrageenan-induced inflammatory pain in rats. Taken together, coadministration of indomethacin or meloxicam with pregabalin may possess potential therapeutic advantages for treating chemotherapy-induced neuropathic pain.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Pyrus pashia Buch ham ex. D. Don (Kainth) fruit from the Himalayan region is traditionally consumed by native people in the form of decoctions for various clinical conditions including inflammatory diseases. However, scientific studies on the biofunctional properties of Kainth fruits are still scarce. AIM OF THE STUDY The study is aimed to investigate the anti-inflammatory effects of Kainth fruit extracts using in vitro and in vivo inflammation models. MATERIAL AND METHODS Free, esterified and bound fractions from the Kainth ethanolic extracts were prepared for determining the anti-inflammatory effect. The levels of 5-LOX and COX-2 were determined in vitro. The protein levels of cytokines (IL-6, TNF-α & IL-10) were quantitated by ELISA method in lipopolysaccharide-stimulated RAW macrophages. Also, the anti-inflammatory potential of the Kainth fruit extracts was determined using the carrageenan-induced mice paw edema model. The bioaccessibility of Kainth fruit extracts was measured using a simulated in vitro digestion system (salivary, gastric and intestinal). RESULTS The Kainth fruit extracts were partially purified to yield free, esterified and bound phenolics. Free and bound phenolics of Kainth fruits inhibited 5-Lipoxygenase, Cyclooxygenase-2 activities and pro-inflammatory cytokines (Interleukin-6 and tumour necrosis factor-α) expression in vitro. Also, oral administration of these extracts to the carrageenan-injected mice showed an anti-inflammatory effect by decreasing the pro-inflammatory cytokines and reducing the cellular infiltration in paw tissues. Also, both the extracts showed better bioavailability and bioaccessibility in in vitro and in vivo studies. CONCLUSIONS The results indicated that free and bound phenolics from Kainth fruits that are rich in catechin, epicatechin, arbutin and chlorogenic acid exhibited anti-inflammatory effects and could potentially be used to treat inflammatory diseases.

Abstract
Inflammatory pain is a complex process that has a substantial negative impact on post-injury quality of life. Astaxanthin (AST), which is a lipid-soluble red-orange carotenoid that is found in lobsters, inhibits the development and maintenance of inflammation in mice via its antioxidant and anti-inflammatory activities. However, the specific mechanisms underlying these effects remain unclear. In this study, we aimed to elucidate the mechanism by which astaxanthin alleviated inflammation using a mouse model with Complete Freund's adjuvant (CFA)-induced inflammatory pain. Mechanical allodynia and thermal hyperalgesia were observed on days 1-14 post CFA injection. Expression of p38 mitogen-activated protein kinase (MAPK) in the left paw and L4-6 dorsal root ganglia (DRG) were upregulated in the CFA-induced mice. Expression of the nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathways were also increased. Astaxanthin relieved mechanical allodynia and thermal hyperalgesia induced by CFA and inhibited the inflammatory response (e.g., infiltration of inflammatory cells and production of inflammatory factors) in the ipsilateral paw and DRG. Additionally, AST inhibited p38 MAPK and enhanced Nrf2/HO-1 contents in the left paw and DRG, and reversed the pain induced by p38 MAPK agonist and Nrf2 inhibitors. These findings suggest that AST exerts anti-inflammatory effects and regulates p38 MAPK and Nrf2/HO-1 to alleviate inflammatory pain. AST may be a potential therapeutic agent for relieving inflammation.

Abstract
One of the main functions of the sensory system in our body is to maintain somatosensory homeostasis. Recent reports have led to a significant advance in our understanding of pain signaling mechanisms; however, the exact mechanisms of pain transmission have remained unclear. There is an urgent need to reveal the precise signaling mediators of pain to provide alternative therapeutic agents with more efficacy and fewer side effects. Accordingly, although the anti-inflammatory, antioxidative and anti-neuropathic effects of astaxanthin (AST) have been previously highlighted, its peripheral antinociceptive mechanisms are not fully understood. In this line, considering the engagement of l-arginine/nitric oxide (NO)/cyclic GMP (cGMP)/potassium channel (KATP) signaling pathway in the antinociceptive responses, the present study evaluated its associated role in the antinociceptive activity of AST. Male mice were intraperitoneally (i.p.) injected with l-arginine (100 mg/kg), SNAP (1 mg/kg), L-NAME (30 mg/kg), sildenafil (5 mg/kg), and glibenclamide (10 mg/kg) alone and prior to the most effective dose of AST. Following AST administration, intraplantarly (i.pl) injection of formalin was done, and pain responses were evaluated in mice during the primary (acute) and secondary (inflammatory) phases of formalin test. The results highlighted that 10 mg/kg i.p. dose of AST showed the greatest antinociceptive effect. Besides, while L-NAME and glibenclamide reduced the antinociceptive effect of AST, it was significantly increased by l-arginine, SNAP and sildenafil during both the primary and secondary phases of formalin test. These data suggest that the antinociceptive activity of AST is passing through the l-arginine/NO/cGMP/KATP pathway.

Abstract
Astaxanthin (AST) is a red pigmented carotenoid with significant antioxidant, anti-inflammatory, anti-proliferative, and anti-apoptotic properties. In this study, we summarize the available literature on the anti-inflammatory efficacy of AST in various chronic and acute disorders, such as neurodegenerative, renal-, hepato-, skin- and eye-related diseases, as well as gastrointestinal disorders. In addition, we elaborated on therapeutic efficacy of AST and the role of several pathways, including PI3K/AKT, Nrf2, NF-κB, ERK1/2, JNK, p38 MAPK, and JAK-2/STAT-3 in mediating its effects. However, additional experimental and clinical studies should be performed to corroborate the anti-inflammatory effects and protective effects of AST against inflammatory diseases in humans. Nevertheless, this review suggests that AST with its demonstrated anti-inflammatory property may be a suitable candidate for drug design with novel technology.

Abstract
We studied the osteoarthritis (OA)-modifying effects of atorvastatin in an experimental OA rat model and possible underlining mechanisms. We used 62 adult male Sprague-Dawley rats (250-300 g): 32 rats were used to assess the effects of atorvastatin on surgically induced OA in the knee, and 30 rats were used to assess the potential inflammatory effects of carrageenan-induced paw edema. In the OA model, joint stiffness was assessed by measuring the knee extension angle, and pathological changes in the OA knee joint were determined by histological examination and the measurement of serum biochemical markers, including interleukin-1β (IL-1β), matrix metalloproteinase-13 (MMP-13), and reduced glutathione (GSH). In the carrageenan-induced paw edema model, both paw thickness and pain threshold were assessed in different groups. Atorvastatin significantly improved joint stiffness, pathological changes, a significant mitigation of the higher MMP-13 and IL-1β, and a significant increase of reduced GSH in OA rats. Additionally, atorvastatin significantly improved both paw thickness and pain threshold in animals. Atorvastatin is a potential OA-modifying drug that warrants further clinical investigation.

Abstract
Neurological disorders are diseases of the central and peripheral nervous system that affect millions of people, and the numbers are rising gradually. In the pathogenesis of neurodegenerative diseases, the roles of many signaling pathways were elucidated; however, the exact pathophysiology of neurological disorders and possible effective therapeutics have not yet been precisely identified. This necessitates developing multi-target treatments, which would simultaneously modulate neuroinflammation, apoptosis, and oxidative stress. The present review aims to explore the potential therapeutic use of astaxanthin (ASX) in neurological and neuroinflammatory diseases. ASX, a member of the xanthophyll group, was found to be a promising therapeutic anti-inflammatory agent for many neurological disorders, including cerebral ischemia, Parkinson's disease, Alzheimer's disease, autism, and neuropathic pain. An effective drug delivery system of ASX should be developed and further tested by appropriate clinical trials.

Abstract
Astaxanthin is a natural lipid-soluble and red-orange carotenoid. Due to its strong antioxidant property, anti-inflammatory, anti-apoptotic, and immune modulation, astaxanthin has gained growing interest as a multi-target pharmacological agent against various diseases. In the current review, the anti-inflammation mechanisms of astaxanthin involved in targeting for inflammatory biomarkers and multiple signaling pathways, including PI3K/AKT, Nrf2, NF-κB, ERK1/2, JNK, p38 MAPK, and JAK-2/STAT-3, have been described. Furthermore, the applications of anti-inflammatory effects of astaxanthin in neurological diseases, diabetes, gastrointestinal diseases, hepatic and renal diseases, eye and skin disorders, are highlighted. In addition to the protective effects of astaxanthin in various chronic and acute diseases, we also summarize recent advances for the inconsistent roles of astaxanthin in infectious diseases, and give our view that the exact function of astaxanthin in response to different pathogen infection and the potential protective effects of astaxanthin in viral infectious diseases should be important research directions in the future.

Abstract
Osteoarthritis (OA) is a degenerative joint disease and a leading cause of adult disability. Since there is no cure for OA and no effective treatment to slow its progression, current pharmacologic treatments, such as analgesics and non-steroidal anti-inflammatory drugs (NSAIDs), only alleviate symptoms, such as pain and inflammation, but do not inhibit the disease process. Moreover, chronic intake of these drugs may result in severe adverse effects. For these reasons, patients have turned to the use of various complementary and alternative approaches, including diverse dietary supplements and nutraceuticals, in an effort to improve symptoms and manage or slow disease progression. The present study was conducted to evaluate the anti-osteoarthritic effects of FlexPro MD® (a mixture of krill oil, astaxanthin, and hyaluronic acid; FP-MD) in a rat model of OA induced by monosodium iodoacetate (MIA). FP-MD significantly ameliorated joint pain and decreased the severity of articular cartilage destruction in rats that received oral supplementation for 7 days prior to MIA administration and for 21 days thereafter. Furthermore, FP-MD treatment significantly reduced serum levels of the articular cartilage degeneration biomarkers cartilage oligomeric matrix protein (COMP) and crosslinked C-telopeptide of type II collagen (CTX-II), and the pro-inflammatory cytokines tumor necrosis factor alpha (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6), as well as mRNA expression levels of inflammatory mediators, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2), and matrix-degrading enzymes, matrix metalloproteinase (MMP)-2 and MMP-9, in the knee joint tissue. Our findings suggest that FP-MD is a promising dietary supplement for reducing pain, minimizing cartilage damage, and improving functional status in OA, without the disadvantages of previous dietary supplements and medicinal agents, including multiple adverse effects.

Abstract
Date (Phoenix dactylifera L.) seeds are seen as good drug to cure rheumatoid arthritis and asthma in Moroccan traditional medicine. The present research aimed to study the anti-inflammatory effect, of methanol extract of different date seed varieties using membrane stabilizing effect, nitric oxide radical scavenging activity, inhibition of protein denaturation, carrageenan-induced paw edema and croton oil induced ear edema. The polyphenolic profile was examined using HPLC-DAD. Rutin, quercetin, p-coumaric and caffeic acids were the main among the analysed phenolic compounds. Concerning the anti-inflammatory activity, the analysed date seed were significantly effective in scavenging nitric oxide free radical, in stabilisation of erythrocyte membrane and possessed a high anti denaturation effect. In agreement with this finding, date seed exhibited a profound ability to reduce paw and ear swelling induced by carrageenan and croton oil respectively. The biochemical parameters showed that date seed are able to reduce the erythrocyte sedimentation rate (ERS) and C-reactive protein (CRP) concentration in rats used in Carrageenan-induced paw edema model. The predominant phenolic compounds are the potential candidates that drive these activities and the differences observed among varieties are related to their chemical composition. These data suggest that date seeds can be explored as a therapeutic agent for the treatment of inflammatory diseases.

Effects of Astaxanthin from Shrimp Shell on Oxidative Stress and Behavior in Animal Model of Alzheimer's Disease. Mar Drugs 2019; 17:md17110628. [PMID: 31690015 PMCID: PMC6891431 DOI: 10.3390/md17110628] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2019] [Revised: 10/29/2019] [Accepted: 10/29/2019] [Indexed: 12/22/2022] Open
Abstract
This study aimed to investigate the effect of astaxanthin (ASX) extracted and ASX powder from shrimp (Litopenaeus vannamei) shells on Wistar rats with Alzheimer's disease, induced by amyloid-β (1-42) peptides. In this task, the rats were divided into eight groups: (1) Control, (2) sham operate, (3) negative control (vehicle) + Aβ1-42, (4) ASX extract+Aβ1-42, (5) commercial ASX + Aβ1-42, (6) ASX powder + Aβ1-42, (7) blank powder + Aβ1-42, and (8) vitamin E + Aβ1-42. All treatments were orally administrated for 30 days. At 14- and 29-days post injection, animals were observed in behavioral tests. On the 31st day, animals were sacrificed; the hippocampus and cortex were collected. Those two brain areas were then homogenized and stored for biochemical and histological analysis. The results showed that the Aβ1-42 infused group significantly reduced cognitive ability and increased memory loss, as assessed by the Morris water maze test, novel object recognition test, and novel object location test. Moreover, the Aβ1-42 infused group exhibited a deterioration of oxidative markers, including glutathione peroxidase enzymes (GPx), lipid peroxidation (MDA), products of protein oxidation, and superoxide anion in the cortex and the hippocampus. Meanwhile, ASX powder (10 mg/kg body weight) showed a significant reduction in cognitive and memory impairments and oxidative stress which is greater than ASX extract in the same dose of compound or vitamin E (100 mg/kg body weight). Our study indicates the beneficial properties of ASX in alleviation of cognitive functions and reducing neurodegeneration in Wistar rats induced by amyloid-β (1-42) peptides.

Abstract
As the leading causes of human disability and mortality, neurological diseases affect millions of people worldwide and are on the rise. Although the general roles of several signaling pathways in the pathogenesis of neurodegenerative disorders have so far been identified, the exact pathophysiology of neuronal disorders and their effective treatments have not yet been precisely elucidated. This requires multi-target treatments, which should simultaneously attenuate neuronal inflammation, oxidative stress, and apoptosis. In this regard, astaxanthin (AST) has gained growing interest as a multi-target pharmacological agent against neurological disorders including Parkinson’s disease (PD), Alzheimer’s disease (AD), brain and spinal cord injuries, neuropathic pain (NP), aging, depression, and autism. The present review highlights the neuroprotective effects of AST mainly based on its anti-inflammatory, antioxidative, and anti-apoptotic properties that underlies its pharmacological mechanisms of action to tackle neurodegeneration. The need to develop novel AST delivery systems, including nanoformulations, targeted therapy, and beyond, is also considered.

Eur J Pain 2018; 23:750-764. [PMID: 30427581 DOI: 10.1002/ejp.1342] [Citation(s) in RCA: 39] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2018] [Revised: 10/04/2018] [Accepted: 11/08/2018] [Indexed: 12/28/2022]
Abstract
BACKGROUND Spinal cord injury (SCI) causes continuous neurological deficits and major sensory-motor impairments. There is no effective treatment to enhance sensory-motor function following SCI. Thus, it is crucial to develop novel therapeutics for this particular patient population. Astaxanthin (AST) is a strong antioxidant, anti-inflammatory and anti-apoptotic agent. In the present study, it was tested in a severe compression SCI model with emphasis on sensory-motor outcomes, signalling pathway, along with other complications. METHODS A severe SCI was induced by compression of the rat thoracic spinal cord with an aneurysm clip and treatment with AST or the vehicle was carried out, 30 min after injury. Behavioural tests including open field, von Frey, hot plate and BBB were performed weekly to 28 days post-injury. Rats were assigned to measure blood glucose, weight and auricle temperature. Western blot and histological analysis also were performed at the same time points. RESULTS AST decreased mechanical and thermal pain and also improved motor function performance, reduced blood glucose and auricle temperature increases and attenuated weight loss in SCI rats. Western blot analysis showed decreased activation of ERK1/2 and increased activation of AKT following AST treatment. The histology results revealed that AST considerably preserved myelinated white matter and the number of motor neurons following SCI. CONCLUSION Taken together, the beneficial effects of AST to improve sensory-motor outcomes, attenuate pathological tissue damage and modulate ERK and AKT signalling pathways following SCI, suggest it as a strong therapeutic agent towards clinical applications. SIGNIFICANCE Spinal cord injury (SCI) impairs sensory-motor function and causes complications, which astaxanthin (AST) has the potential to be used as a treatment for. The present study investigates the effects of AST in a compression model of SCI with emphasis on sensory-motor outcomes alongside other complications, histopathological damage and also related signalling pathways.

Astaxanthin attenuates neuroinflammation contributed to the neuropathic pain and motor dysfunction following compression spinal cord injury. Brain Res Bull 2018; 143:217-224.

Abstract
Spinal cord injury (SCI) is a debilitating condition in which inflammatory responses in the secondary phase of injury leads to long lasting sensory-motor dysfunction. The medicinal therapy of SCI complications is still a clinical challenge. Understanding the molecular pathways underlying the progress of damage will help to find new therapeutic candidates. Astaxanthin (AST) is a ketocarotenoid which has shown anti-inflammatory effects in models of traumatic brain injury. In the present study, we examined its potential in the elimination of SCI damage through glutamatergic-phospo p38 mitogen-activated protein kinase (p-p38MAPK) signaling pathway. Inflammatory response, histopathological changes and sensory-motor function were also investigated in a severe compression model of SCI in male rats. The results of acetone drop and inclined plane tests indicated the promising role of AST in improving sensory and motor function of SCI rats. AST decreased the expression of n-methyl-d-aspartate receptor subunit 2B (NR2B) and p-p38MAPK as inflammatory signaling mediators as well as tumor necrosis factor-α (TNF-α) as an inflammatory cytokine, following compression SCI. The histopathological study culminated in preserved white mater and motor neurons beyond the injury level in rostral and caudal parts. The results show the potential of AST to inhibit glutamate-initiated signaling pathway and inflammatory reactions in the secondary phase of SCI, and suggest it as a promising candidate to enhance functional recovery after SCI.

Abstract
Despite considerable advances in understanding mechanisms involved in chronic pain, effective treatment remains limited. Astaxanthin, a marine natural drug, having potent anti-oxidant and anti-inflammatory activities is known to possess neuroprotective effects. However, effects of astaxanthin against nerve injury induce chronic pain remains unknown. Overactivity of glutamatergic NMDARs results in excitotoxicity which may participate in astrocytic and microglial activation during pathology which further contribute to the development of neuropathic pain. In this study, we investigate the effects of astaxanthin on oxido-inflammatory and NMDA receptor down-regulation pathway by using in-silico, in-vitro and in-vivo models of neuropathic pain. In-silico molecular docking study ascertained the binding affinity of astaxanthin to NMDA receptors and showed antagonistic effects. Data from in-vitro studies suggest that astaxanthin significantly reduces the oxidative stress induced by the lipopolysaccharides in C6 glial cells. In male Sprague dawley rats, a significant attenuation of neuropathic pain behavior was observed in Hargreaves test and von Frey hair test after astaxanthin treatment. Findings from the current study suggest that astaxanthin can be used as potential alternative in the treatment of chronic neuropathic pain. However, more detailed investigations are required to further probe the in-depth mechanism of action of astaxanthin.

Abstract
BACKGROUND/OBJECTIVES Re-epithelialization has an important role in skin wound healing. Astaxanthin (ASX), a carotenoid found in crustaceans including shrimp, crab, and salmon, has been widely used for skin protection. Therefore, we investigated the effects of ASX on proliferation and migration of human skin keratinocyte cells and explored the mechanism associated with that migration. MATERIAL/METHOD HaCaT keratinocyte cells were exposed to 0.25-1 µg/mL of ASX. Proliferation of keratinocytes was analyzed by using MTT assays and flow cytometry. Keratinocyte migration was determined by using a scratch wound-healing assay. A mechanism for regulation of migration was explored via immunocytochemistry and western blot analysis. RESULTS Our results suggest that ASX produces no significant toxicity in human keratinocyte cells. Cell-cycle analysis on ASX-treated keratinocytes demonstrated a significant increase in keratinocyte cell proliferation at the S phase. In addition, ASX increased keratinocyte motility across the wound space in a time-dependent manner. The mechanism by which ASX increased keratinocyte migration was associated with induction of filopodia and formation of lamellipodia, as well as with increased Cdc42 and Rac1 activation and decreased RhoA activation. CONCLUSIONS ASX stimulates the migration of keratinocytes through Cdc42, Rac1 activation and RhoA inhibition. ASX has a positive role in the re-epithelialization of wounds. Our results may encourage further in vivo and clinical study into the development of ASX as a potential agent for wound repair.
