[PMID: 38804629 DOI: 10.1080/14786419.2024.2358387] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Accepted: 05/15/2024] [Indexed: 05/29/2024]
Abstract
This bibliometric review examines the current state of research on fucoidan, a sulphated polysaccharide found in brown seaweed species, and its potential for wound healing. The review included 58 studies that investigated fucoidan's effects on wound healing, revealing that it possesses anti-inflammatory and antioxidant properties that could aid in the healing process. Fucoidan was also found to promote cell proliferation, migration, and angiogenesis, essential for wound healing. However, the optimal dosage, treatment duration, safety, and efficacy of fucoidan in various wound types and patient populations still require further investigation. Additionally, advanced wound dressings like hydrogels have garnered significant attention for their potential in wound healing. While this review indicates promise for fucoidan as a natural wound healing compound, it underscores the need for additional clinical trials to determine its optimal use as a commercial therapeutic agent in wound healing.

[PMID: 38554920 DOI: 10.1016/j.ijbiomac.2024.131220] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2023] [Revised: 03/21/2024] [Accepted: 03/26/2024] [Indexed: 04/02/2024]
Abstract
Diabetic wound healing remains a healthcare challenge due to the overexpression of matrix metalloproteinase-9 (MMP-9) and the imbalance between angiogenic factors and vascular inhibitory factors. In this study, we developed a nanocomposite injectable collagen/chitosan hydrogel for the treatment of delayed diabetic wound healing, which can promote cell migration to the wound site (through the addition of phycocyanin) and reduce the expression of MMP-9 (through the use of ND-336) to improve the therapeutic effect of diabetic wound healing. Furthermore, different weight ratios of collagen and chitosan hydrogels were prepared to select the hydrogel with proper mechanical properties. In vitro experiments confirmed that all hydrogels have favorable biocompatibility and hemocompatibility. Notably, Gel 2, with a weight ratio of collagen and chitosan at 25:75, was found to have an excellent capability to facilitate cell migration and in vivo studies further proved that Gel 2 nanocomposite hydrogel had the best ability to improve diabetic wound healing by promoting cell migration and decreasing MMP-9 expression. The collagen/chitosan/genipin hydrogel loaded phycocyanin and ND-336 can be harnessed for non-toxic and efficient treatment of wound healing management of diabetes.

Abstract
The paper proposed a new porous material for wound healing based on chitosan and C-phycocyanin (C-PC). In this work, C-PC was extracted from the cyanobacteria Arthrospira platensis biomass and purified through ammonium sulfate precipitation. The obtained C-PC with a purity index (PI) of 3.36 ± 0.24 was loaded into a chitosan sponge from aqueous solutions of various concentrations (250, 500, and 1000 mg/L). According to the FTIR study, chitosan did not form new bonds with C-PC, but acted as a carrier. The encapsulation efficiency value exceeded 90%, and the maximum loading capacity was 172.67 ± 0.47 mg/g. The release of C-PC from the polymer matrix into the saline medium was estimated, and it was found 50% of C-PC was released in the first hour and the maximum concentration was reached in 5-7 h after the sponge immersion. The PI of the released C-PC was 3.79 and 4.43 depending on the concentration of the initial solution.

Abstract
Wound healing is widely recognized as a critical issue impacting the healthcare sector in numerous countries. The application of wound dressings multiple times in such instances can result in tissue damage, thereby increasing the complexity of wound healing. With the aim of tackling this necessity, in the present study, we have formulated a hydrogel using natural polysaccharide κ-carrageenan and phycobiliprotein R-phycoerythrin from Pyropia yezoensis. The formulated hydrogel κ-Carrageenan-R-Phycoerythrin (κ-CRG-R-PE) was analyzed for its antioxidant and antimicrobial activity. The wound healing potential of the κ-CRG-R-PE was evaluated in Hs27 cells by the wound scratch assay method. The hydrogel showed dose-dependent antioxidant activity and significant antimicrobial activity at 100 μg/mL concentration. κ-CRG-R-PE hydrogels promoted more rapid and complete wound closure than κ-Carrageenan (κ-CRG) hydrogel at 24 and 48 h. κ-CRG-R-PE hydrogels also filled the wound within 48 h of incubation, indicating that they positively affect fibroblast migration and wound healing.

Pharmaceuticals (Basel) 2023; 16:ph16040592. [PMID: 37111349 PMCID: PMC10144176 DOI: 10.3390/ph16040592] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 04/10/2023] [Accepted: 04/12/2023] [Indexed: 04/29/2023] Open
Abstract
Large-scale production of microalgae and their bioactive compounds has steadily increased in response to global demand for natural compounds. Spirulina, in particular, has been used due to its high nutritional value, especially its high protein content. Promising biological functions have been associated with Spirulina extracts, mainly related to its high value added blue pigment, phycocyanin. Phycocyanin is used in several industries such as food, cosmetics, and pharmaceuticals, which increases its market value. Due to the worldwide interest and the need to replace synthetic compounds with natural ones, efforts have been made to optimize large-scale production processes and maintain phycocyanin stability, which is a highly unstable protein. The aim of this review is to update the scientific knowledge on phycocyanin applications and to describe the reported production, extraction, and purification methods, including the main physical and chemical parameters that may affect the purity, recovery, and stability of phycocyanin. By implementing different techniques such as complete cell disruption, extraction at temperatures below 45 °C and a pH of 5.5-6.0, purification through ammonium sulfate, and filtration and chromatography, both the purity and stability of phycocyanin have been significantly improved. Moreover, the use of saccharides, crosslinkers, or natural polymers as preservatives has contributed to the increased market value of phycocyanin.

Protective Effect of the Phycobiliproteins from Arthrospira maxima on Indomethacin-Induced Gastric Ulcer in a Rat Model. PLANTS (BASEL, SWITZERLAND) 2023; 12:1586.

Abstract
Gastric ulcers (GU) constitute a disease with a global prevalence ≈ 8.09 million. Of their causes, non-steroidal anti-inflammatory drugs (NSAIDs) such as indomethacin (IND) rank as the second most frequent etiologic agent. The pathogenic process of gastric lesions is given by the overproduction of oxidative stress, promotion of inflammatory processes, and inhibition of prostaglandin synthesis. Spirulina Arthrospira maxima (SP) is a cyanobacterium with a wide variety of substances with high nutritional and health values such as phycobiliproteins (PBPs) that have outstanding antioxidant activity, anti-inflammatories effects, and accelerate the wound healing process. This study aimed to determine the protective effect of PBPs in GU induced by IND 40 mg/kg. Our results show that the PBPs protected against IND-induced damage with a dose-dependent effect. At a dose of 400 mg/kg, a marked decrease in the number of lesions is observed, as well as the recovery of the main markers of oxidative stress damage (MDA) and antioxidant species (SOD, CAT, GPx) at close to baseline levels. The evidence derived from the present investigation suggests that the antioxidant effect of PBPs, together with their reported anti-inflammatory effects to accelerate the wound healing process, is the most reliable cause of their antiulcerogenic activity in this GU model.

Abstract
Biopolymer-based thermoresponsive injectable hydrogels with multifunctional tunable characteristics containing anti-oxidative, biocompatibility, anti-infection, tissue regeneration, and/or anti-bacterial are of abundant interest to proficiently stimulate diabetic wound regeneration and are considered as a potential candidate for diversified biomedical application but the development of such hydrogels remains a challenge. In this study, the Chitosan-CMC-g-PF127 injectable hydrogels are developed using solvent casting. The Curcumin (Cur) Chitosan-CMC-g-PF127 injectable hydrogels possess viscoelastic behavior, good swelling properties, and a controlled release profile. The degree of substitution (% DS), thermal stability, morphological behavior, and crystalline characteristics of the developed injectable hydrogels is confirmed using nuclear magnetic resonance (1H NMR), thermogravimetric analysis, scanning electron microscopy (SEM), and x-ray diffraction analysis (XRD), respectively. The controlled release of cur-micelles from the hydrogel is evaluated by drug release studies and pharmacokinetic profile (PK) using high-performance liquid chromatography (HPLC). Furthermore, compared to cur micelles the Cur-laden injectable hydrogel shows a significant increase in half-life (t1/2) up to 5.92 ± 0.7 h, mean residence time (MRT) was 15.75 ± 0.76 h, and area under the first moment curve (AUMC) is 3195.62 ± 547.99 μg/mL*(h)2 which reveals the controlled release behavior. Cytocompatibility analysis of Chitosan-CMC-g-PF127 hydrogels using 3T3-L1 fibroblasts cells and in vivo toxicity by subcutaneous injection followed by histological examination confirmed good biocompatibility of Cur-micelles loaded hydrogels. The histological results revealed the promising tissue regenerative ability and shows enhancement of fibroblasts, keratinocytes, and collagen deposition, which stimulates the epidermal junction. Interestingly, the Chitosan-CMC-g-PF127 injectable hydrogels ladened Cur exhibited a swift wound repair potential by up-surging the cell migration and proliferation at the site of injury and providing a sustained drug delivery platform for hydrophobic moieties.

Abstract
Aspirin causes gastrotoxicity and damaged epithelial defense via cyclooxygenase inhibition. C-phycocyanin (CPC) and Lycium barbarum polysaccharides (LBP), an active ingredient of Spirulina platensis and wolfberry, respectively, exerted antioxidation, anti-inflammation, and/or immunoregulation. The actions of CPC and/or LBP on gastric damage induced by aspirin were explored in rat gastric mucosal RGM-1 cells. Gastric injury was performed by 21 mM aspirin for 3 h after the pretreatment of CPC and/or LBP (100-500 μg/mL) for 24 h in RGM-1 cells. Proinflammatory, anti-inflammatory, and apoptotic markers were examined by ELISA or gel electrophoresis and Western blotting. Cell viability and interleukin 10 (IL-10) were reduced by aspirin. Increased proinflammatory markers, caspase 3 activity, and Bax protein were observed in RGM-1 cells with aspirin treatment. Aspirin elevated nuclear factor-κB (NF-κB), extracellular signal-regulated kinase (ERK), p38, and c-Jun N-terminal kinase (JNK) activation, while CPC and/or LBP increased IL-10, and attenuated proinflammatory markers, Bax protein, NF-κB, and the activation of ERK and JNK. Therefore, CPC and/or LBP possess anti-inflammation by restraining the activation of the ERK signaling pathway, and LBP decreases apoptosis by suppressing the JNK signaling pathway activation in gastric RGM-1 cells with aspirin-induced epithelial damage.

Abstract
Cyano-phycocyanin is one of the active pigments of the blue-green algae and is usually isolated from the filamentous cyanobacteria Arthrospira platensis Gomont (Spirulina). Due to its multiple physiological functions and non-toxicity, cyano-phycocyanin may be a potential substance for the topical treatment of various skin diseases. Considering that the conventional medicine faces drug resistance, insufficient efficacy and side effects, the plant origin compounds can act as an alternative option. Thus, the aim of this paper was to review the wound healing, antimicrobial, antioxidative, anti-inflammatory, antimelanogenic and anticancer properties and mechanisms of cyano-phycocyanin topical activities on human skin. Moreover, possible applications and biotechnological requirements for pharmaceutical forms of cyano-phycocyanin for the treatment of various skin diseases are discussed in this review.

Disruption of the reparative process, often found in diabetic patients, results in chronic, non-healing wounds that significantly impact a patient's quality of life. This highlights the need of new therapeutic options to improve the healing of diabetic wounds. In this study, we focused on developing a cell-free hydrogel dressing loaded with mesenchymal stem cell (MSC)-conditioned media (CM) to potentially improve the healing of hard-to-heal wounds. We simulated a hyperglycemic environment by incubating human dermal fibroblasts in a high glucose environment (30 mM) and validated that MSC-CM rescued the impaired functions (proliferation and migration) of hyperglycemic fibroblasts. Further, we investigated the effect of loading MSC-CM in gelatin methacrylate (GelMA)-poly (ethylene glycol) diacrylate (PEGDA) hybrid hydrogels in improving the proliferative activity of glucose-treated fibroblasts. The controlled release of bioactive factors from MSC-CM loaded GelMA-PEGDA hydrogels promoted the metabolic activity of hyperglycemic fibroblasts. In addition, the growth rate of hyperglycemic fibroblasts was found to be similar to that of normal fibroblasts. Our observations, thus, suggest the potential application of cell-free, MSC-secretome-loaded hydrogel in the healing of diabetic or chronic wounds.

Biomarkers of coagulation, endothelial function, and fibrinolysis in critically ill patients with COVID-19: A single-center prospective longitudinal study. J Thromb Haemost 2021; 19:1546-1557. [PMID: 33826233 PMCID: PMC8250276 DOI: 10.1111/jth.15327] [Citation(s) in RCA: 42] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Revised: 03/26/2021] [Accepted: 03/30/2021] [Indexed: 12/21/2022]
Abstract
BACKGROUND Immunothrombosis and coagulopathy in the lung microvasculature may lead to lung injury and disease progression in coronavirus disease 2019 (COVID-19). We aim to identify biomarkers of coagulation, endothelial function, and fibrinolysis that are associated with disease severity and may have prognostic potential. METHODS We performed a single-center prospective study of 14 adult COVID-19(+) intensive care unit patients who were age- and sex-matched to 14 COVID-19(-) intensive care unit patients, and healthy controls. Daily blood draws, clinical data, and patient characteristics were collected. Baseline values for 10 biomarkers of interest were compared between the three groups, and visualized using Fisher's linear discriminant function. Linear repeated-measures mixed models were used to screen biomarkers for associations with mortality. Selected biomarkers were further explored and entered into an unsupervised longitudinal clustering machine learning algorithm to identify trends and targets that may be used for future predictive modelling efforts. RESULTS Elevated D-dimer was the strongest contributor in distinguishing COVID-19 status; however, D-dimer was not associated with survival. Variable selection identified clot lysis time, and antigen levels of soluble thrombomodulin (sTM), plasminogen activator inhibitor-1 (PAI-1), and plasminogen as biomarkers associated with death. Longitudinal multivariate k-means clustering on these biomarkers alone identified two clusters of COVID-19(+) patients: low (30%) and high (100%) mortality groups. Biomarker trajectories that characterized the high mortality cluster were higher clot lysis times (inhibited fibrinolysis), higher sTM and PAI-1 levels, and lower plasminogen levels. CONCLUSIONS Longitudinal trajectories of clot lysis time, sTM, PAI-1, and plasminogen may have predictive ability for mortality in COVID-19.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs such as aspirin are used for the treatment of cardiovascular disease. Chronic use of low-dose aspirin is associated with the occurrence of gastric ulcer. The aim of this study was to investigate the healing potential of Lycium barbarum polysaccharides (LBP) from Chinese Goji berry and C-phycocyanin (CPC) from Spirulina platensis on gastric ulcer in rats. METHODS Male Sprague-Dawley rats were divided into five groups: normal, aspirin (700 mg/kg bw), LBP (aspirin + 100 mg/kg bw/d LBP), CPC (aspirin + 50 mg/kg bw/d CPC), and MIX (aspirin + 50 mg/kg bw/d LBP + 25 mg/kg bw/d CPC) groups. Gastric ulcer was developed by daily oral feeding of aspirin for 8 weeks. Treatments were given orally a week before ulcer induction for 9 weeks. RESULTS The MIX group elevated gastric cyclooxygenase-1, prostaglandin E2, and total nitrite and nitrate levels by 139%, 86%, and 66%, respectively, compared with the aspirin group (p < 0.05). Moreover, the MIX group reduced lipid peroxides malondialdehyde levels by 78% (p < 0.05). The treatment of LBP and/or CPC increased gastric Bifidobacterium relative abundance by 2.5-4.0 times compared with the aspirin group (p < 0.05). CONCLUSIONS We conclude that combined LBP and CPC enhance gastroprotective factors, inhibit lipid peroxidation, and increase gastric Bifidobacterium relative abundance. Combined LBP and CPC have protective potential against gastric ulcer caused by aspirin in rats.

Abstract
Refining nutraceutical conjugated metal nanoparticles (NPs) and understanding their interactions with the cellular micro-environment is necessary for their application in nanomedicine. In the present experiment, we studied the effect of quercetin functionalized gold nanoparticles (AuQurNP) on skin fibroblast and keratinocyte cell migration. Spherical shaped AuQurNPs of 47 nm in size were formed due to the interaction of hydroxyl and carbonyl groups of quercetin with Au atoms as revealed by incremental algorithm-based analysis. AuQurNP containing up to 5 μg l−1 of Au with quercetin (5.2 ± 1.6 ng ml−1) was least toxic to fibroblasts. AuQurNP effectively reduced the generation of intracellular ROS (up to 63%) through free-radical scavenging activity. AuQurNP also enhanced the rate of migration of fibroblasts (24 h) and keratinocytes (20 h) in artificially created wounds. The rate of migration of the cells towards the wound edge was in the order of AuQurNP > control > quercetin > AuNP. AuQurNP also significantly increased the expression of TGFβ1 protein, thereby inducing the downstream SMAD complex (SMAD 2–4). Downregulation of the inhibitory protein SMAD 7 by AuQurNP helped in the nuclear translocation of SMADs 3 and 4. Collectively, the present in vitro study demonstrates the action of AuQurNP on the SMAD family and the interconnected molecular mechanism leading to the cell migration process. AuQuercetin nano conjugates enhances cell migration via TGFβ1.![]()

Abstract
Green synthesis of metal-encased nutraceutical nano-hybrids has been a target for research over the last few years. In the present investigation, we have reported temperature dependent facile synthesis of silver nanoparticles using FDA approved c phycocyanin (cPC). The cPC conjugated silver nanoparticles (AgcPCNPs) were characterized by TEM, Zeta Potential, UV-vis, XPS, FTIR, and CD Spectroscopy. The temperature optimization studies suggested the synthesis of stable AgcPCNPs at 40 °C while at higher temperature system shows aggregated appearance. Molecular docking studies predicted the exclusive interaction of C, D, I, and J chains of cPC with the surface of AgNPs. Moreover, AgcPCNPs significantly (p < 0.1 %) counteract the toxic nature of AgNPs on red blood cell by measuring parameters like total RBC count, % hemolysis, % hematocrit, coagulation time, pH, electrolyte concentrations and degree of blood cell lipid peroxidation by the anti-oxidation mechanism. Skin fibroblast in vitro cell migration result suggeststhat AgcPCNPs enhanced the degree of cell movement towards the wound area. Data obtained collectively demonstrate that AgcPCNPs can be a better agent in the dermal wound healing with reduced toxicity with the bi-phasic advantage of cPC as a wound healer and Ag nano-metal as an anti-bacterial agent.

Acta Biomater 2020; 109:121-131. [PMID: 32335311 DOI: 10.1016/j.actbio.2020.03.023] [Citation(s) in RCA: 37] [Impact Index Per Article: 9.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 03/05/2020] [Accepted: 03/17/2020] [Indexed: 01/05/2023]
Abstract
Wound healing remains a healthcare challenge in patients suffering from grave tissue damage due to burn injuries and severe medical conditions like diabetes and ischemia. A repeated wound dressing in such cases leads to tissue damage, which could further inflate the wound healing. It is also challenging to analyze the depth of wound bed in these conditions, which could affect the recovery period. To address this need, we have developed an injectable hydrogel from natural polysaccharide κ-carrageenan and a pigmented protein C-phycocyanin. C-phycocyanin has wound healing, antimicrobial, antioxidant and anti-inflammatory properties along with the In-vivo fluorescence imaging ability. Gelling property of κ-carrageenan could be utilized along with C-phycocyanin as an injectable and regenerative wound dressings matrix to monitor wound healing in real-time without upsetting the healing process. The hydrogel presented herein was built from ionic crosslinking of κ-carrageenan monomers along with C-phycocyanin, which provides an interconnected network of porous material with hydrophilic surface and mechanical stiffness. This porosity allows nutrients transportation and gaseous exchange across the wound healing site for the proliferation of various cells. Hydrogel material enhances the proliferation of dermal fibroblasts in vitro without inducing inflammation along with reducing the blood clotting time with no haemolysis. We have found that κ-carrageenan-C-phycocyanin (κ-CRG-C-Pc) hydrogel not only exhibit superior haemostatic capabilities in traumatic injury condition but also provide support for rapid wound healing. Overall, these findings demonstrate the potential of κ-carrageenan-C-phycocyanin hydrogels as a wound-healing and imaging platform towards accelerating tissue repair and real-time monitoring. STATEMENT OF SIGNIFICANCE: Blood clotting and inflammation are the most crucial stages of wound healing along with appropriate monitoring of the healing process. Thus, there is a need of system that could provide point-to-point care and monitoring in this multistage process. Here, we have introduced a self healing, injectable hydrogel system with in vivo imaging abilities from κ-carragenan and C-phycocyanin. C-phycocyanin improves the stability of κ-carragenan matrix and provide support to cellular adhesion, proliferation, and migration. Its anti-inflammatory response and rapid blood clotting ability further empower its applicability in critical medical conditions and wound recovery.

Abstract
MicroRNAs (miRNAs) participate in post-transcriptional regulation by targeting the 3' untranslated region of target genes that are involved in diverse biological processes. To the best of our knowledge, the association between miR‑152 and ERBB3 in ovarian cancer remains unclear. In the present study, a negative correlation between miR‑152 and ERBB3 in ovarian cancer was observed. The luciferase reporter gene assay results demonstrated that miR‑152 negatively regulated ERBB3 in SKOV3 and OVCAR3 ovarian cancer cells. Furthermore, our results revealed that miR‑152 suppressed the ability of ovarian cancer cell proliferation, migration and invasion, and promoted apoptosis through inhibiting ERBB3 in vitro. Therefore, in the present study, miR‑152 was found to be involved in the proliferation and metastasis of ovarian cancer cells through repression of ERBB3 expression. Therefore, miR‑152 may be a potential therapeutic target for the treatment of ovarian cancer.

Abstract
Phycocyanin (Pc) is one of the active pigment constituents of Spirulina microalgae. It has been used for its potent antioxidant and anti-inflammatory properties. However, the protective effects of Pc against ultraviolet-B (UVB)-induced primary skin cells damage are still undefined. In the present study, we investigated whether Pc prevented UVB-induced apoptotic cell death in human dermal fibroblasts (HDF) and human epidermal keratinocytes (HEK). Pc induced the transcription of heme oxygenase-1 (HO-1). Furthermore, Pc treatments resulted in a marked increase in nuclear factor erythroid-derived 2 (NF-E2)-like 2 (Nrf-2) nuclear translocation. Also, Pc protected UVB induced apoptosis and reduced the p53 and Bax levels, as well as caspase-3 activation. Pc treatment showed a significantly enhanced effect on the phosphorylation of protein kinase C (PKC) α/β II, but not that of p38 mitogen-activated protein kinase (MAPK) or Akt. Induction of HO-1 induced by Pc was suppressed by Go6976, a selective inhibitor of PKC α/β II. In addition, knockdown of HO-1 by small interfering (siRNA) caused a significant increase in poly (ADP-ribose) polymerase 1 (PARP-1) cleavage and caspase-3 activation after Pc pretreatment. Taken together, our results demonstrate that Pc-induced expression of HO-1 is mediated by the PKC α/β II-Nrf-2/HO-1 pathway, and inhibits UVB-induced apoptotic cell death in primary skin cells.

Abstract
In recent years, marine natural pigments have emerged as a powerful alternative in the various fields of food, cosmetic, and pharmaceutical industries because of their excellent biocompatibility, bioavailability, safety, and stability. Marine organisms are recognized as a rich source of natural pigments such as chlorophylls, carotenoids, and phycobiliproteins. Numerous studies have shown that marine natural pigments have considerable medicinal potential and promising applications in human health. In this review, we summarize the marine natural pigments as potential sources for therapeutic applications, including: antioxidant, anticancer, antiangiogenic, anti-obesity, anti-inflammatory activities, drug delivery, photothermal therapy (PTT), photodynamic therapy (PDT), photoacoustic imaging (PAI), and wound healing. Marine natural pigments will offer a better platform for future theranostic applications.

Abstract
Spirulina platensis :have been studied for several biological activities. In the current study C-phycocyanin containing protein extract (C-PC extract) of Spirulina platensis have been studied for its effect on human matrix metalloproteinases (MMP-1, MMP-2 and MMP-9) and tissue inhibitors of MMPs (TIMP-1 and TIMP-2). In the present study, breast cancer cell line (MDA-MB 231) and hepatocellular cancer cell line (HepG2) were examined for inhibition of MMPs at different levels of expression after C-PC extract treatment. Herein, we have demonstrated that C-PC extract significantly reduced activity of MMP-2 by 55.13% and MMP-9 by 57.9% in HepG2 cells at 15 μg concentration. Additionally, the treatment has reduced mRNA expression of MMP-2 and MMP-9 at 20 μg concentration by 1.65-folds and 1.66-folds respectively. The C-PC extract treatment have also downregulated a mRNA expression of TIMP-2 by 1.12 folds at 20 μg concentration in HepG2 cells. Together, these results indicate that C-PC, extract successfully inhibited MMP-2 and -9 at different levels of expression and TIMP-2 at a mRNA expression level; however, extract did not have any effect on MMP-1 expressed in MDA-MB231 and TIMP-1 expressed in HepG2 cells as well as the exact mechanism of inhibition of MMP-2, MMP-9 and TIMP-2 remained unclear.

Abstract
The purpose of this study was to explore the potential role of HOTAIR in thyroid cancer carcinogenesis. We found that HOTAIR was unregulated in human thyroid cancer and inversely correlated with miR-1. Functional assays indicated HOTAIR regulates miR-1 directly in thyroid cancer cells. We also revealed that HOTAIR promotes the processes of thyroid cancer cell malignancy through regulation of microRNA-1 (miR-1). Furthermore, we showed that HOTAIR could regulate a downstream target of miR-1, CCND2, in a miR-1-mediated manner. In addition, we also proved, using a tumor formation assay in nude mice, that silencing HOTAIR inhibited tumor formation in vivo. Therefore, our study demonstrated that HOTAIR promotes the development and progression of thyroid cancer through inhibition of microRNA-1 and activation of CCND2.

Abstract
BACKGROUND Osteoporosis is a bone pathology leading to increased fracture risk and challenging the quality of life. As current treatments can exhibit deleterious side effects, the use of phyto-compounds with therapeutic and preventive activities against orthopaedic related problems represents a promising alternative. PURPOSE We investigated the effect of aloin, an anthrocyclic compound, on inhibition of osteoclastogenesis using receptor of the nuclear factor κB (NF-κB) ligand (RANKL)-induced RAW264.7 macrophage cells. STUDY DESIGN/METHODS The inhibitory effect of aloin on in vitro osteoclastogenesis was evaluated by reduction in tartrate-resistant acid phosphatase (TRAP) content and expression levels of osteoclast-specific gene, cathepsin K. Multinuclear formation of osteoclast was assessed with haematoxylin and eosin staining. F4/80 content the marker of the murine monocyte/macrophage cells, was evaluated by immunocytochemistry. The underlining mechanisms were assessed by Western blots and EMSA. Effect of aloin on generation of intracellular reactive oxygen species (ROS) was estimated by dichlorofluorescein diacetate (DCFH-DA). Bone degradation effect was evaluated by bone pit assay. The bone pit culture supernatant was studied by Fluorescein assay. RESULTS We demonstrated that aloin reduced TRAP content and levels of osteoclast-specific gene and protein, cathepsin K. Treatment with aloin (0.75 µM) prevented multinuclear formation (haematoxylin and eosin staining), reduced intracellular TRAP content (TRAP Staining) and increased F4/80 content (F4/80 immunohistochemistry) in RANKL (20 ng/ml) treated RAW cells. Treatment of the RAW cells with aloin suppressed RANKL-induced NF-κB pathway components like IKKα, IKKβ, Phospho.IKK α/β, NF-κB-p65, Phospho NF-κB-p65 and IκBα. EMSA studies showed aloin dose dependently reduced DNA binding activity of NF-κB. Additionally, in vitro bone pit assay revealed that aloin prevented bone degradation and also decreased the fluorescence content in cells, thus confirming the role of aloin in inhibition of osteoclastogenesis . CONCLUSION Collectively, this study identifies aloin as a potent inhibitor of osteoclastogenesis and bone resorption. The action of aloin was in par with alendronate sodium trihydrate and may provide evidence for its therapeutic potential to treat diseases involving abnormal bone lysis.

Abstract
The effects of C-phycocyanin (C-pc), a phycobiliprotein, on the expression of pro-fibrotic mediators in hyper-tropic scarring such as connective tissue growth factor (CTGF) and α-smooth muscle actins (α-SMA) were investigated in relation to trans-differentiation of fibroblast to myo-fibroblast, an icon of scar formation. C-pc was isolated from Spirulina Platensis extract using sonication method and C-pc concentration was determined by Bennet and Bogorad equation. α-SMA and CTGF levels in wounded primary human dermal fibroblasts were determined by western blot analysis and immuno-fluorescence confocal microscope was employed. Fibroblast contractility was examined by three-dimensional collagen lattice contraction assay. There was an elevation of α-SMA (121%) and CTGF (143%) levels in wound cells as compared with non-wound cells. The does-response profiles of down regulation demonstrated that the maximum inhibitions of α-SMA by 63% (p<0.05) and CTGF by 50% (p<0.1) were achieved by C-pc (6 nM) treated cells. In confocal assay, non-wound fibroblasts exhibited basal level of α-SMA staining, while wounded cells without C-pc treatment showed strong up-regulation of α-SMA by 147% (p<0.05). C-pc (6 nM) inhibited α-SMA expression by 70% (p<0.05) and reduced collagen contraction by 29% (p<0.05). C-pc seemed to lessen the over expression of CTGF, α-SMA, subsequently alleviating the fibrotic contracture. This study suggests the potential application of C-pc to regulation of the expression of pro-fibrotic mediators in scarring process and its potential usage as an efficient means for anti-fibrosis therapy.

Abstract
After spinal cord injury (SCI), disruption of blood–spinal cord barrier (BSCB) elicits blood cell infiltration such as neutrophils and macrophages, contributing to permanent neurological disability. Previous studies show that epidermal growth factor (EGF) produces potent neuroprotective effects in SCI models. However, little is known that whether EGF contributes to the integrity of BSCB. The present study is performed to explore the mechanism of BSCB permeability changes which are induced by EGF treatment after SCI in rats. In this study, we demonstrate that EGF administration inhibits the disruption of BSCB permeability and improves the locomotor activity in SCI model rats. Inhibition of the PI3K/Akt pathways by a specific inhibitor, LY294002, suppresses EGF‐induced Rac1 activation as well as tight junction (TJ) and adherens junction (AJ) expression. Furthermore, the protective effect of EGF on BSCB is related to the activation of Rac1 both in vivo and in vitro. Blockade of Rac1 activation with Rac1 siRNA downregulates EGF‐induced TJ and AJ proteins expression in endothelial cells. Taken together, our results indicate that EGF treatment preserves BSCB integrity and improves functional recovery after SCI via PI3K‐Akt‐Rac1 signalling pathway.

Abstract
A major complication of diabetes mellitus is the disruption of normal wound repair process, characterised by insufficient production of growth factors. A molecular genetic approach wherein resident cells synthesise and deliver the growth factors to the wound site would be a powerful therapeutic strategy to treat diabetic wounds. One such molecular approach could be the application of microRNAs (miRNAs). This study reports differential expression of miRNAs related to cell development and differentiation, during wound healing in diabetic mice. Comparison of skin tissue from normal and diabetic mice showed that 14 miRNAs were differentially expressed in diabetic skin; miR-146b and miR-21 were the most noteworthy. Expression pattern of these miRNAs was also altered during healing of diabetic wounds. A subset of miRNAs (miR-20b, miR-10a, miR-10b, miR-96, miR-128, miR-452 and miR-541) exhibited similar basal levels in normal and diabetic skins, but displayed dysregulation during healing of diabetic wounds. Amongst the miRNAs studied, miR-21 showed a distinct signature with increased expression in diabetic skin but decreased expression during diabetic wound healing. We analysed the role of miR-21 in fibroblast migration, because migration of fibroblasts into the wound area is an important landmark facilitating secretion of growth factors and migration of other cell types into the wound, thus enhancing the healing process. Using gain-of and loss-of function approaches, we show that miR-21 is involved in fibroblast migration. Our preliminary studies implicate an important role for miRNAs in the pathogenesis of diabetic wounds.

Abstract
Background Pigmentation is one of the essential defense mechanisms against oxidative stress or UV irradiation; however, abnormal hyperpigmentation in human skin may pose a serious aesthetic problem. C-phycocyanin (Cpc) is a phycobiliprotein from spirulina and functions as an antioxidant and a light harvesting protein. Though it is known that spirulina has been used to reduce hyperpigmentation, little literature addresses the antimelanogenic mechanism of Cpc. Herein, we investigated the rationale for the Cpc-induced inhibitory mechanism on melanin synthesis in B16F10 melanoma cells. Methods Cpc-induced inhibitory effects on melanin synthesis and tyrosinase expression were evaluated. The activity of MAPK pathways-associated molecules such as MAPK/ERK and p38 MAPK, were also examined to explore Cpc-induced antimelanogenic mechanisms. Additionally, the intracellular localization of Cpc was investigated by confocal microscopic analysis to observe the migration of Cpc. Results Cpc significantly (P < 0.05) reduced both tyrosinase activity and melanin production in a dose-dependent manner. This phycobiliprotein elevated the abundance of intracellular cAMP leading to the promotion of downstream ERK1/2 phosphorylation and the subsequent MITF (the transcription factor of tyrosinase) degradation. Further, Cpc also suppressed the activation of p38 causing the consequent disturbed activation of CREB (the transcription factor of MITF). As a result, Cpc negatively regulated tyrosinase gene expression resulting in the suppression of melanin synthesis. Moreover, the entry of Cpc into B16F10 cells was revealed by confocal immunofluorescence localization and immunoblot analysis. Conclusions Cpc exerted dual antimelanogenic mechanisms by upregulation of MAPK/ERK-dependent degradation of MITF and downregulation of p38 MAPK-regulated CREB activation to modulate melanin formation. Cpc may have potential applications in biomedicine, food, and cosmetic industries.

Abstract
Tumor invasion and metastasis present major obstacles to successful control of androgen-independent prostate cancer. Cell migration is a fundamental aspect of cancer cell metastasis. Urokinase plasminogen activator (uPA) system is implicated in cell migration and cancer metastasis and has potential to be developed as therapeutic target. In recent years, efficacy of dietary nutrients in preventing and curing cancer has gained increasing attention. One such promising candidate is proanthocyanidin-rich grape seed extract (GSE). We investigated the efficacy of GSE in regulating uPA expression and cell migration using highly metastatic androgen-independent PC3 prostate cancer cells as a model. GSE down-regulated uPA as a function of concentration. Additional studies showed that GSE inhibited DNA-binding activity of the transcription factor nuclear factor kappa B (NFkappaB), which in turn decreased NFkappaB-dependent uPA transcription. Invasion assays revealed the inhibitory effect of GSE on PC3 cell migration. These in-vitro experiments demonstrate the therapeutic property of GSE as an antimetastatic agent by targeting uPA.

Abstract
Urokinase plasminogen activator (uPA) plays a vital role in the early phases of wound healing by aiding fibrin dissolution and promoting the migration, proliferation, and adhesion of various cells to the wound bed. The efficacy of botanicals in healing wounds is an area of active research. Among these, curcumin, a yellow pigment abundant in turmeric rhizome, has been the center of extensive studies. This study focused on the effect of curcumin on uPA expression and its consequence on fibrin dissolution and cellular migration. Treatment of human fibroblast cells with curcumin caused an upregulation of uPA mRNA and protein. Activation of JNK and p38 MAPK signal pathways was necessary for the upregulation of uPA. Curcumin treatment resulted in an increase in fibrinolytic activity and cell migration towards the wound area. The involvement of uPA in fibrinolysis and cell migration was confirmed by zymography and siRNA studies, respectively.

Abstract
The urokinase-type plasminogen activator (uPA) and the main uPA inhibitor PAI-1 play important roles in cell migration and invasion in both physiological and pathological contexts. Both factors are clinically applicable predictive markers in node-negative breast cancer patients that are used to stratify patients for adjuvant chemotherapy. In addition to their classical functions in plasmin regulation, both factors are key components in cancer-related cell signalling. Such signalling cascades are well described in cell culture systems, but a better understanding of uPA- and PAI-1-associated signalling networks in clinical tissues is needed. We examined the expression of uPA, PAI-1, and 21 signalling molecules in 201 primary breast cancer tissues using protein microarrays. Expression of uPA was significantly correlated with the expression of ERK and Stat3, while expression of PAI-1 was correlated with the uPA receptor and Akt activation, presumably via integrin and HER-receptor signalling. Analysis of uPA expression did not reveal any significant correlation with staging, grading or age of the patients. The PAI-1 expression was correlated with nodal stage. Network monitoring for uPA and PAI-1 in breast cancer reveals interactions with main signalling cascades and extends the findings from cell culture experiments. Our results reveal possible mechanisms underlying cancer development.

Moulager M, Corellou F, Vergé V, Escande ML, Bouget FY. Integration of light signals by the retinoblastoma pathway in the control of S phase entry in the picophytoplanktonic cell Ostreococcus. PLoS Genet 2010; 6:e1000957. [PMID: 20502677 PMCID: PMC2873908 DOI: 10.1371/journal.pgen.1000957] [Citation(s) in RCA: 51] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2009] [Accepted: 04/20/2010] [Indexed: 01/09/2023] Open
Abstract
Although the decision to proceed through cell division depends largely on the metabolic status or the size of the cell, the timing of cell division is often set by internal clocks such as the circadian clock. Light is a major cue for circadian clock entrainment, and for photosynthetic organisms it is also the main source of energy supporting cell growth prior to cell division. Little is known about how light signals are integrated in the control of S phase entry. Here, we present an integrated study of light-dependent regulation of cell division in the marine green alga Ostreococcus. During early G1, the main genes of cell division were transcribed independently of the amount of light, and the timing of S phase did not occur prior to 6 hours after dawn. In contrast S phase commitment and the translation of a G1 A-type cyclin were dependent on the amount of light in a cAMP–dependent manner. CyclinA was shown to interact with the Retinoblastoma (Rb) protein during S phase. Down-regulating Rb bypassed the requirement for CyclinA and cAMP without altering the timing of S phase. Overexpression of CyclinA overrode the cAMP–dependent control of S phase entry and led to early cell division. Therefore, the Rb pathway appears to integrate light signals in the control of S phase entry in Ostreococcus, though differential transcriptional and posttranscriptional regulations of a G1 A-type cyclin. Furthermore, commitment to S phase depends on a cAMP pathway, which regulates the synthesis of CyclinA. We discuss the relative involvements of the metabolic and time/clock signals in the photoperiodic control of cell division. Microalgae from phytoplankton play an essential role in the biogeochemical cycles through carbon dioxide assimilation in the oceans where they account for more than half of organic carbon production. Photosynthetic cells use light energy for cell growth, but light can also reset the circadian clock, which is involved in the timing of cell division. How light signals are integrated in the control of cell division remains largely unknown in photosynthetic cells. We have used the marine picoeukaryotic alga Ostreococcus to dissect the molecular mechanisms of light-dependent control of cell division. We found that the Retinoblastoma pathway integrates light signals which regulate the synthesis of CyclinA in response to cAMP. Alteration of CyclinA or Rb levels triggers cell division in limiting light conditions and bypasses the need for cAMP. In addition, CyclinA overexpression affects the timing of S phase entry. This first integrated study of light-dependent regulation of cell division in photosynthetic cells provides insight into the underlying molecular mechanisms.

Abstract
Abstract
Objectives
The aim of this work was to investigate the anti-inflammatory activity of C-phycocyanin (C-PC) on skin inflammation after topical administration and the influence of liposomal delivery on its pharmacokinetic properties.
Methods
Liposomes of different size and structure were prepared with different techniques using soy phosphatidylcholine and cholesterol. Vesicular dispersions were characterised by transmission electron microscopy, optical and fluorescence microscopy for vesicle formation and morphology, dynamic laser light scattering for size distribution, and Zetasizer for zeta-potential. C-PC skin penetration and permeation experiments were performed in vitro using vertical diffusion Franz cells and human skin treated with either free or liposomal drug dispersed in a Carbopol gel.
Key findings
The protein was mainly localised in the stratum corneum, while no permeation of C-PC through the whole skin thickness was detected. Two percent C-PC-encapsulating liposomes showed the best drug accumulation in the stratum corneum and the whole skin, higher than that of the corresponding free 2% C-PC gel. Moreover, skin deposition of liposomal C-PC was dose dependent since skin accumulation values increased as the C-PC concentration in liposomes increased. The topical anti-inflammatory activity of samples was evaluated in vivo as inhibition of croton oil-induced or arachidonic acid-induced ear oedema in rats.
Conclusions
The results showed that C-PC can be successfully used as an anti-inflammatory drug and that liposomal encapsulation is effective in improving its anti-inflammatory activity.

Abstract
Urokinase plasminogen activator (uPA) system, comprising of uPA, its receptor uPAR and inhibitor, type 1 plasminogen activator inhibitor (PAI-1), plays a vital role in various biological processes involving extracellular proteolysis, fibrinolysis, cell migration and proliferation. The timely occurence of these processes are essential for normal wound healing. This study examines the regulation of uPA and PAI-1 by a natural polyphenol-rich compound, grape seed extract (GSE). GSE is reported to have beneficial effects in promoting wound healing. Fibroblast cells exposed to different doses of GSE for 18hours were processed for further studies such as ELISA, RT-PCR, western blotting, fibrinolytic assay, cell surface plasmin activity assay and in vitro wound healing assay. GSE treatment caused a significant downregulation of uPA and PAI-1 expression, both at the RNA and protein levels. ELISA also revealed a dose-dependent decrease in uPA and PAI-1 activities. Functional significance of the downregulation was evident in decreased fibrinolytic activity, concomittant with decreased cell-surface plasmin activity. In vitro wound healing studies showed that GSE also retarded the migration of cells towards the wounded region.

Abstract
This study analyzed the effects of biliprotein C-phycocyanin (C-PC) on the enzymatic antioxidant defence system in lymphocytes of nuclear power-plant workers and non-exposed controls. Changes in the protein levels of manganese super oxide dismutase (MnSOD), catalase and glutathione-S-transferase (GST) were used as markers for early biological effects of a single in vitro exposure of cells to: (i) 2Gy gamma rays; (ii) 5muM C-PC; and (iii) a combination of C-PC plus irradiation with 2Gy. The results showed that C-PC selectively stimulated the lymphocyte antioxidant defence system of occupationally exposed subjects. The activation of the antioxidant protective mechanisms as part of the early radiation response was probably related to the chronic low-dose occupational exposure. The modulating capacity of C-PC at the molecular level may be of interest for the protection of occupationally exposed persons.
