Int J Biol Macromol 2023; 253:127623. [PMID: 37879586 PMCID: PMC10842036 DOI: 10.1016/j.ijbiomac.2023.127623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2023] [Revised: 10/20/2023] [Accepted: 10/21/2023] [Indexed: 10/27/2023]
Abstract
Hydrostatic pressure can reversibly modulate protein-protein and protein-chromophore interactions of C-phycocyanin (C-PC) from Spirulina platensis. Small-angle X-ray scattering combined with UV-Vis spectrophotometry and protein modeling was used to explore the color and structural changes of C-PC under high pressure conditions at different pH levels. It was revealed that pressures up to 350 MPa were enough to fully disassemble C-PC from trimers to monomers at pH 7.0, or from monomers to detached subunits at pH 9.0. These disassemblies were accompanied by protein unfolding that caused these high-pressure induced structures to be more extended. These changes were reversible following depressurization. The trimer-to-monomer transition proceeded through a collection of previously unrecognized, L-shaped intermediates resembling C-PC dimers. Additionally, pressurized C-PC showed decayed Q-band absorption and fortified Soret-band absorption. This was evidence that the folded tetrapyrroles, which had folded at ambient pressure, formed semicyclic unfolded conformations at a high pressure. Upon depressurization, the peak intensity and shift all recovered stepwise, showing pressure can precisely manipulate C-PC's structure as well as its color. Overall, a protein-chromophore regulatory theory of C-PC was unveiled. The pressure-tunability could be harnessed to modify and stabilize C-PC's structure and photochemical properties for designing new delivery and optical materials.

Spirulina phycocyanin extract and its active components suppress epithelial-mesenchymal transition process in endometrial cancer via targeting TGF-beta1/SMAD4 signaling pathway. Biomed Pharmacother 2022; 152:113219. [PMID: 35691155 DOI: 10.1016/j.biopha.2022.113219] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2022] [Revised: 05/25/2022] [Accepted: 05/30/2022] [Indexed: 12/23/2022] Open
Abstract
Metastasis is a major challenge in aggressive endometrial cancer treatment accounting for the high recurrence risk and poor prognosis of epithelial-mesenchymal transition (EMT), regulated by the transforming growth factor beta (TGFβ) signaling pathway, facilitates tumor metastasis. Spirulina phycocyanin extract (SPE) and its purified products allophycocyanin (APC) and C-phycocyanin (C-PC), derived from Spirulina platensis, can be considered a nutraceutical compound with the ability to inhibit tumor growth and metastasis. Current study aims to investigate the anti-metastatic potential of SPE, and its purified products APC, and C-PC on endometrial cancer both in vitro and in vivo. Firstly, human endometrial cancer cell lines (HEC-1A and Ishikawa) as an in vitro model. Secondly, HEC-1A cells transfected with luminescence gene were implanted into female nude mice as a xenograft model. MTT assay, transwell migration assay, immunoblotting assay, quantitative real-time polymerase chain reaction assay, and IVIS XRMS analysis techniques were used. The in vitro results showed that SPE and its purified products APC and C-PC inhibited cell migration, and altered the expression of EMT-related phenotypes by reversing the TGFβ/SMADs signaling pathway. The in vivo results indicated that SPE repressed the metastasis of HEC-1A-LUC cells through modulating EMT-related markers expression. Overall, SPE and its efficient components APC and C-PC reversed the EMT through targeting the TGFβ/SMADs signaling pathway, suggesting an effective therapeutic strategy for metastatic endometrial cancer.

Abstract
Breast cancer has consistently had the highest incidence among women in the world. Tumor cell-derived extracellular vesicles (EV) have been leveraged as drug carriers for cancer treatment. Herein, we developed an efficient theranostic platform for breast cancer-specific delivery of lipophilic triphenylphosphonium (TPP)-modified therapeutic recombinant P53 proteins (TPP/P53) by breast cancer cell-derived EVs. We observed that the EVs were routinely captured by their patent cells, so when, TPP/P53 was loaded into the EVs (TPP/P53@EVs), TPP/P53 was targeted to the mitochondria of breast cancer cells, where it caused signal amplification and induced the death of breast cancer cells. Our findings demonstrated that the TPP/P53@EVs showed good tumor-targeting capability and efficiently destroyed the tumor tissues without any obvious toxicity in vivo. Therefore, our TPP/P53@EVs might provide a "drug-free" strategy for future applications in breast cancer therapy.

Abstract
Environment-triggered protein conformational changes have garnered wide interest in both fundamental research, for deciphering in vivo acclimatory responses, and practical applications, for designing stimuli-responsive probes. Here, we propose a protein-chromophore regulatory mechanism that allows for manipulation of C-phycocyanin (C-PC) from Spirulina platensis by environmental pH and UV irradiation. Using small-angle X-ray scattering, a pH-mediated C-PC assembly-disassembly pathway, from monomers to nonamers, was unraveled. Such flexible protein matrices impart tunability to the embedded tetrapyrroles, whose photochemical behaviors were found to be modulated by protein assembly states. UV irradiation on C-PC triggers pH-dependent singlet oxygen (1O2) generation and conformational changes. Intermolecular photo-crosslinking occurs at pH 5.0 via dityrosine species, which bridges solution-based C-PC oligomers into unprecedented dodecamers and 24-mers. These supramolecular assemblies impart C-PC at pH 5.0, which significantly enhanced 1O2 yield, fluorescence, and photostability relative to those at other pH values, a finding that makes C-PC appealing for tumor-targeted photodynamic therapy.

Abstract
To achieve synergistic photodynamic-photothermic therapy, we fabricate the novel phycocyanin (PC)-functionalized black phosphorus quantum dots (BPQDs) referred as PC@BPQDs through a one-step stirring method. PC@BPQDs are characterized by the feature of possessing both near-infrared (NIR) induced photothermal and photodynamic activity. The PC layer not only effectively alleviates plasma protein adsorption onto BPQDs, but also functionally boosts the photothermal therapy efficiency by enhanced ROS release, resulting in increased apoptosis in vitro. Moreover, PC@BPQDs eradicate tumors with high efficacy and low toxicity in vivo. Thus, PC@BPQDs have a promising potential in future therapeutic implications.

Abstract
A combination treatment strategy that relies on the synergetic effects of different therapeutic approaches has been considered to be an effective method for cancer therapy. Herein, a chemotherapeutic drug (doxorubicin, Dox) and a manganese ion (Mn2+) were co-loaded into regenerated silk fibroin-based nanoparticles (NPs), followed by the surface conjugation of phycocyanin (PC) to construct tumor microenvironment-activated nanococktails. The resultant PC-Mn@Dox-NPs showed increased drug release rates by responding to various stimulating factors (acidic pH, hydrogen peroxide (H2O2), and glutathione), revealing that they could efficiently release the payloads (Dox and Mn2+) in tumor cells. The released Dox could not only inhibit the growth of tumor cells but also generated a large amount of H2O2. The elevated H2O2 was decomposed into the highly harmful hydroxyl radicals and oxygen through an Mn2+-mediated Fenton-like reaction. Furthermore, the generated oxygen participated in photodynamic therapy (PDT) and produced abundant singlet oxygen. Our investigations demonstrate that these PC-Mn@Dox-NPs exhibit multiple bioresponsibilities and favorable biosafety. By integrating Dox-induced chemotherapy, Mn2+-mediated chemodynamic therapy, and PC-based PDT via cascade reactions, PC-Mn@Dox-NPs achieved enhanced in vitro and in vivo anticancer efficacies compared to all the mono- or dual-therapeutic approaches. These findings reveal that PC-Mn@Dox-NPs can be exploited as a promising nanococktail for cascade reaction-mediated synergistic cancer treatment.

Abstract
The application of cytostatic drugs or natural substances to inhibit cancer growth and progression is an important and evolving subject of cancer research. There has been a surge of interest in marine bioresources, particularly algae, as well as cyanobacteria and their bioactive ingredients. Dried biomass products of Arthrospira and Chlorella have been categorized as “generally recognized as safe” (GRAS) by the US Food and Drug Administration (FDA). Of particular importance is an ingredient of Arthrospira: phycocyanin, a blue-red fluorescent, water-soluble and non-toxic biliprotein pigment. It is reported to be the main active ingredient of Arthrospira and was shown to have therapeutic properties, including anti-oxidant, anti-inflammatory, immune-modulatory and anti-cancer activities. In the present review, in vitro and in vivo data on the effects of phycocyanin on various tumor cells and on cells from healthy tissues are summarized. The existing knowledge of underlying molecular mechanisms, and strategies to improve the efficiency of potential phycocyanin-based anti-cancer therapies are discussed.

It has numerous applications in the field of biotechnology and drug industry and also possesses antioxidant, anticancer, antiinflammatory, enhanced immune function, including liver and kidney protection properties. The molecular mechanism of action of C-PC for its anticancer activity could be the blockage of cell cycle progression, inducing apoptosis and autophagy in cancer cells. OBJECTIVES The current review summarizes an update on therapeutic applications of C-PC, its mechanism of action and mainly focuses on the recent development in the field of C-PC as a drug that exhibits beneficial effects against various human diseases including cancer and inflammation. CONCLUSION The data from various studies suggest the therapeutic applications of C-PC such as anti-cancer activity, anti-inflammation, anti-angiogenic activity and healing capacity of certain autoimmune disorders. Mechanism of action of C-PC for its anticancer activity is the blockage of cell cycle progression, inducing apoptosis and autophagy in cancer cells. The future perspective of C-PC is to identify and define the molecular mechanism of its anti-cancer, anti-inflammatory and antioxidant activities, which would shed light on our knowledge on therapeutic applications of C-PC and may contribute significant benefits to global public health.

Abstract
Background Breast cancer is one of the most commonly diagnosed cancers in women, with high morbidity and mortality. Tumor metastasis is implicated in most breast cancer deaths; thus, inhibiting metastasis may provide a therapeutic direction for breast cancer. In the present study, pyropheophorbide-α methyl ester-mediated photodynamic therapy (MPPa-PDT) was used to inhibit metastasis in MCF-7 breast cancer cells. Methods Uptake of MPPa was detected by fluorescence microscopy. Cell viability was evaluated by the Cell Counting Kit-8 (CCK-8). ROS generation was detected by 2′,7′-dichlorodihydrofluorescein diacetate (DCFH-DA). The migration of cells was assessed by wound healing assay, and invasion ability was assessed by Matrigel invasion assay. Levels of MMP2 and MMP9 were measured by PCR. Akt, phospho-Akt (Ser473), phospho-NF-κB p65 (Ser536) and NF-κB p65 were measured by western blotting. The F-actin cytoskeleton was observed by immunofluorescence. Lung tissue was visualized by hematoxylin and eosin staining. Results Following MPPa-PDT, migration and invasion were decreased in the MCF-7 cells. MPPa-PDT downregulated the expression of MMP2 and MMP9, which are responsible for the initiation of metastasis. MPPa-PDT reduced the phosphorylation of Akt and NF-κB. MPPa-PDT also reduced the expression of F-actin in cytoskeleton in MCF-7 cells. These effects were blocked by the reactive oxygen species scavenger NAC or the Akt activator SC79, while the PI3K inhibitor LY294002 or the Akt inhibitor triciribine enhanced these effects. Moreover, MPPa-PDT inhibited tumor metastasis and destroyed F-actin in vivo. Conclusion Taken together, these results demonstrate that MPPa-PDT inhibits the metastasis of MCF-7 cells both in vitro and in vivo and may be involved in the Akt/NF-κB-dependent MMP-9 signaling pathway. Thus, MPPa-PDT may be a promising treatment to inhibit metastasis.

Abstract
Photodynamic therapy has been efficiently applied for cancer therapy. Here, we have fabricated the folic acid (FA)- and pheophorbide A (PA)-conjugated FA/PA@Fe3O4 nanoparticle (smart hybrid nanocomposite, SHN) to enhance the photodynamic inactivation (PDI) of specific cancer cells. SHN coated with the PDI agent is designed to have selectivity for the folate receptor (FR) expressed on cancer cells. Structural characteristics and morphology of the fabricated MNPs were studied with X-ray diffraction and scanning electron microscopy. The photophysical properties of SHN were investigated with absorption, emission spectroscopies, and Fourier transform infrared spectroscopy. In addition, the magnetic property of Fe3O4 nanoparticle (MNP) can be utilized for the collection of SHNs by an external magnetic field. The photofunctionality was given by the photosensitizer, PA, which generates reactive oxygen species by irradiation of visible light. Generation of singlet oxygen was directly evaluated with time-resolved phosphorescence spectroscopy. Biocompatibility and cellular interaction of SHN were also analyzed by using various cancer cells, such as KB, HeLa, and MCF-7 cells which express different levels of FR on the surface. Cellular adsorption and the PDI effect of SHN on the various cancer cells in vitro were correlated well with the surface expression levels of FR, suggesting potential applicability of SHN on specific targeting and PDI of FR-positive cancers.

Synthesis and photodynamic activity of novel non-symmetrical diaryl porphyrins against cancer cell lines. JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2019; 195:39-50. [PMID: 31075653 DOI: 10.1016/j.jphotobiol.2019.04.010] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/23/2018] [Revised: 03/23/2019] [Accepted: 04/25/2019] [Indexed: 12/28/2022]
Abstract
Photodynamic therapy (PDT) of cancer uses photosensitizers (PS), a light source and oxygen to generate high levels of reactive oxygen species (ROS), that exert a cytotoxic action on tumor cells. Recently, it has been shown that mixed non-symmetrical diaryl porphyrins, with two different pendants, are more photodynamically active than symmetrical diaryl porphyrins. In the present study, we investigate the in vitro photodynamic effects of four novel non-symmetrical diaryl porphyrins, two of which bear one pentafluoro-phenyl and one bromo-alkyl (apolar) pendant, whereas the two others bear one pentafluoro-phenyl and one cationic pyridine pendant. The four compounds were tested in a small panel of human cancer cell lines, and their photodynamic activities were compared with that of m-THPC (Foscan), currently the most successful PS approved for clinical use in cancer PDT. The results of the cytotoxicity studies indicate that the two molecules bearing the cationic pendant are more potent in vitro than those with the apolar pendant, and that they are as potent as Foscan. To gain further insights into the mechanism of PS-induced phototoxicity, induction of apoptotic, autophagic and necrotic cell death, and generation of reactive oxygen species (ROS) were evaluated in cancer cells following exposure to the PSs and irradiation. The effect of the PSs on the migratory activity of the cells was also assessed. The data obtained from this work support a greater potency of diaryl porphyrins with a positive charge in inducing cell death, as compared to those with the bromo-alkyl pendant; most importantly, some of these novel compounds exhibit features that might make them superior to the clinically approved PS Foscan.

Mexican Microalgae Biodiversity and State-Of-The-Art Extraction Strategies to Meet Sustainable Circular Economy Challenges: High-Value Compounds and Their Applied Perspectives. Mar Drugs 2019; 17:E174. [PMID: 30889823 PMCID: PMC6470790 DOI: 10.3390/md17030174] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2019] [Revised: 03/05/2019] [Accepted: 03/09/2019] [Indexed: 02/05/2023] Open
Abstract
In recent years, the demand for naturally derived products has hiked with enormous pressure to propose or develop state-of-the-art strategies to meet sustainable circular economy challenges. Microalgae possess the flexibility to produce a variety of high-value products of industrial interests. From pigments such as phycobilins or lutein to phycotoxins and several polyunsaturated fatty acids (PUFAs), microalgae have the potential to become the primary producers for the pharmaceutical, food, and agronomical industries. Also, microalgae require minimal resources to grow due to their autotrophic nature or by consuming waste matter, while allowing for the extraction of several valuable side products such as hydrogen gas and biodiesel in a single process, following a biorefinery agenda. From a Mexican microalgae biodiversity perspective, more than 70 different local species have been characterized and isolated, whereas, only a minimal amount has been explored to produce commercially valuable products, thus ignoring their potential as a locally available resource. In this paper, we discuss the microalgae diversity present in Mexico with their current applications and potential, while expanding on their future applications in bioengineering along with other industrial sectors. In conclusion, the use of available microalgae to produce biochemically revenuable products currently represents an untapped potential that could lead to the solution of several problems through green technologies. As such, if the social, industrial and research communities collaborate to strive towards a greener economy by preserving the existing biodiversity and optimizing the use of the currently available resources, the enrichment of our society and the solution to several environmental problems could be attained.
