Skeletonema marinoi Extracts and Associated Carotenoid Fucoxanthin Downregulate Pro-Angiogenic Mediators on Prostate Cancer and Endothelial Cells. Cells 2023; 12:cells12071053. [PMID: 37048126 PMCID: PMC10093511 DOI: 10.3390/cells12071053] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2022] [Revised: 03/17/2023] [Accepted: 03/24/2023] [Indexed: 04/03/2023] Open
Abstract
The exploration of natural preventive molecules for nutraceutical and pharmaceutical use has recently increased. In this scenario, marine microorganisms represent an underestimated source of bioactive products endowed with beneficial effects on health that include anti-oxidant, anti-inflammatory, differentiating, anti-tumor, and anti-angiogenic activities. Here, we tested the potential chemopreventive and anti-angiogenic activities of an extract from the marine coastal diatom Skeletonema marinoi Sarno and Zingone (Sm) on prostate cancer (PCa) and endothelial cells. We also tested one of the main carotenoids of the diatom, the xanthophyll pigment fucoxanthin (Fuco). Fuco from the literature is a potential candidate compound involved in chemopreventive activities. Sm extract and Fuco were able to inhibit PCa cell growth and hinder vascular network formation of endothelial cells. The reduced number of cells was partially due to growth inhibition and apoptosis. We studied the molecular targets by qPCR and membrane antibody arrays. Angiogenesis and inflammation molecules were modulated. In particular, Fuco downregulated the expression of Angiopoietin 2, CXCL5, TGFβ, IL6, STAT3, MMP1, TIMP1 and TIMP2 in both prostate and endothelial cells. Our study confirmed microalgae-derived drugs as potentially relevant sources of novel nutraceuticals, providing candidates for potential dietary or dietary supplement intervention in cancer prevention approaches.

BIOTECHNOLOGY FOR BIOFUELS AND BIOPRODUCTS 2023; 16:28. [PMID: 36803279 PMCID: PMC9940373 DOI: 10.1186/s13068-023-02277-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 12/02/2022] [Accepted: 02/04/2023] [Indexed: 06/18/2023]
Abstract
BACKGROUND Microalgae represent a suitable and eco-sustainable resource for human needs thanks to their fast growth ability, together with the great diversity in species and intracellular secondary bioactive metabolites. These high-added-value compounds are of great interest for human health or animal feed. The intracellular content of these valuable compound families is tightly associated with the microalgal biological state and responds to environmental cues, e.g., light. Our study develops a Biotechnological response curve strategy exploring the bioactive metabolites synthesis in the marine cyanobacterium Spirulina subsalsa over a light energy gradient. The Relative Light energy index generated in our study integrates the red, green and blue photon flux density with their relative photon energy. The Biotechnological response curve combined biochemical analysis of the macromolecular composition (total protein, lipid, and carbohydrate content), total sterols, polyphenols and flavonoids, carotenoids, phenolic compounds, vitamins (A, B1, B2, B6, B9, B12, C, D2, D3, E, H, and K1), phycobiliproteins, together with the antioxidant activity of the biomass as well as the growth ability and photosynthesis. RESULTS Results demonstrated that light energy significantly modulate the biochemical status of the microalga Spirulina subsalsa revealing the relevance of the light energy index to explain the light-induced biological variability. The sharp decrease of the photosynthetic rate at high light energy was accompanied with an increase of the antioxidant network response, such as carotenoids, total polyphenols, and the antioxidant capacity. Conversely, low light energy favorized the intracellular content of lipids and vitamins (B2, B6, B9, D3, K1, A, C, H, and B12) compared to high light energy. CONCLUSIONS Results of the Biotechnological response curves were discussed in their functional and physiological relevance as well as for the essence of their potential biotechnological applications. This study emphasized the light energy as a relevant tool to explain the biological responses of microalgae towards light climate variability, and, therefore, to design metabolic manipulation of microalgae.

The Microalgal Diatoxanthin Inflects the Cytokine Storm in SARS-CoV-2 Stimulated ACE2 Overexpressing Lung Cells. Antioxidants (Basel) 2022; 11:antiox11081515. [PMID: 36009234 PMCID: PMC9405469 DOI: 10.3390/antiox11081515] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 08/01/2022] [Accepted: 08/02/2022] [Indexed: 12/10/2022] Open
Abstract
Contact between SARS-CoV-2 and human lung cells involves the viral spike protein and the human angiotensin-converting enzyme 2 (ACE2) receptor on epithelial cells, the latter being strongly involved in the regulation of inflammation as well as blood pressure homeostasis. SARS-CoV-2 infection is characterized by a strong inflammatory response defined as a “cytokine storm”. Among recent therapeutic approaches against SARS-CoV-2 targeting the dramatic inflammatory reaction, some natural products are promising. Diatoms are microalgae able to produce bioactive secondary metabolites, such as the xanthophyll diatoxanthin (Dt). The aim of this study is to demonstrate the anti-inflammatory effects of Dt on the A549-hACE2 lung cell line, exploring its interaction with the ACE2 receptor, as well as depicting its role in inhibiting a cytokine storm induced by the SARS-CoV-2 spike glycoprotein. Results showed that Dt enhanced the cell metabolism, e.g., the percent of metabolically active cells, as well as the ACE2 enzymatic activity. Moreover, Dt strongly affected the response of the SARS-CoV-2 spike glycoprotein-exposed A549-hACE2 cells in decreasing the interleukin-6 production and increasing the interleukin-10 release. Moreover, Dt upregulated genes encoding for the interferon pathway related to antiviral defense and enhanced proteins belonging to the innate immunity response. The potential interest of Dt as a new therapeutic agent in the treatment and/or prevention of the severe inflammatory syndrome related to SARS-CoV-2 infection is postulated.

Potential for the Production of Carotenoids of Interest in the Polar Diatom Fragilariopsis cylindrus. Mar Drugs 2022; 20:md20080491. [PMID: 36005496 PMCID: PMC9409807 DOI: 10.3390/md20080491] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2022] [Revised: 07/15/2022] [Accepted: 07/27/2022] [Indexed: 01/25/2023] Open
Abstract
Carotenoid xanthophyll pigments are receiving growing interest in various industrial fields due to their broad and diverse bioactive and health beneficial properties. Fucoxanthin (Fx) and the inter-convertible couple diadinoxanthin–diatoxanthin (Ddx+Dtx) are acknowledged as some of the most promising xanthophylls; they are mainly synthesized by diatoms (Bacillariophyta). While temperate strains of diatoms have been widely investigated, recent years showed a growing interest in using polar strains, which are better adapted to the natural growth conditions of Nordic countries. The aim of the present study was to explore the potential of the polar diatom Fragilariopsis cylindrus in producing Fx and Ddx+Dtx by means of the manipulation of the growth light climate (daylength, light intensity and spectrum) and temperature. We further compared its best capacity to the strongest xanthophyll production levels reported for temperate counterparts grown under comparable conditions. In our hands, the best growing conditions for F. cylindrus were a semi-continuous growth at 7 °C and under a 12 h light:12 h dark photoperiod of monochromatic blue light (445 nm) at a PUR of 11.7 μmol photons m−2 s−1. This allowed the highest Fx productivity of 43.80 µg L−1 day−1 and the highest Fx yield of 7.53 µg Wh−1, more than two times higher than under ‘white’ light. For Ddx+Dtx, the highest productivity (4.55 µg L−1 day−1) was reached under the same conditions of ‘white light’ and at 0 °C. Our results show that F. cylindrus, and potentially other polar diatom strains, are very well suited for Fx and Ddx+Dtx production under conditions of low temperature and light intensity, reaching similar productivity levels as model temperate counterparts such as Phaeodactylum tricornutum. The present work supports the possibility of using polar diatoms as an efficient cold and low light-adapted bioresource for xanthophyll pigments, especially usable in Nordic countries.
