Molecular changes in oysters Crassostrea gigas (Thunberg, 1793) from aquaculture areas of Santa Catarina Island bays (Florianópolis, Brazil) reveal anthropogenic effects. CHEMOSPHERE 2022; 307:135735. [PMID: 35868530 DOI: 10.1016/j.chemosphere.2022.135735] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 07/07/2022] [Accepted: 07/12/2022] [Indexed: 06/15/2023]
Abstract
Anthropogenic activities in coastal regions cause risks to the environmental and human health. Due to the carcinogenic and mutagenic potential, polycyclic aromatic hydrocarbons (PAH) are considered priority for monitoring. Most of the Brazilian production of Crassostrea gigas oysters are placed in the Bays of Santa Catarina Island. The aim of this study was to evaluate molecular responses (phase I and II of biotransformation and antioxidant defense) of C. gigas from six oyster farming areas potentially contaminated by sanitary sewage in Florianópolis Metropolitan (SC, Brazil): Santo Antônio de Lisboa, Sambaqui, Serraria, Caieira, Tapera, Imaruim. We evaluated the transcript levels of CYP1A1-like, CYP2-like, CYP2AU2-like, CYP356A1, GSTA1A-like, GSTO.4A-like, SULT-like, SOD-like and CAT-like by qRT-PCR. Only oysters from Caieira showed levels of thermotolerant coliforms allowed by the law. Chemicals analyses in soft tissues of oysters showed low to average levels of PAH in all monitored areas. Enhanced transcript levels of phase I (CYP1A1-like, CYP3564A1-like, CYP2-like and CYP2AU2-like) were observed in oysters from Serraria and Imaruí, suggesting higher biotransformation activity in these farming areas. Regarding phase II of biotransformation, GSTO.4A-like was up-regulated in oysters from Imaruí compared to Caieira and Santo Antônio de Lisboa. An upregulation of SOD-like and CAT-like were observed in oysters from Imaruí and Serraria, suggesting that oysters from these sites are facing higher prooxidant conditions compared to other areas. By integrating the biological and chemical data it is suggested that human-derived contaminants are affecting the oyster metabolism in some farming areas.

Kida M, Nakamura T, Murata T. A novel eicosapentaenoic acid-derived anti-inflammatory lipid mediator 5,6-DiHETE is abundant in blue back fish intestines. J Food Sci 2020; 85:1983-1987. [PMID: 32572984 DOI: 10.1111/1750-3841.15179] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 04/18/2020] [Accepted: 04/22/2020] [Indexed: 01/03/2023]
Abstract
Because omega-3 fatty acids, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and their metabolites are known to possess anti-inflammatory and health-promoting functions in human and experimental animals, their intake is assumed to be beneficial for maintaining our health. We previously identified a cytochrome P450-metabolite of EPA, 5,6-dihydroxy-8Z,11Z,14Z,17Z-eicosatetraenoic acid (5,6-DiHETE), as a novel bioactive lipid, which inhibits vascular hyperpermeability in inflammation. Because blue back fishes including sardine, mackerel, and horse mackerel are reported to contain high concentrations of omega-3 fatty acids, we investigated which tissue of blue back fish is suitable as a source of 5,6-DiHETE. We measured the concentration of 5,6-DiHETE as well as major fatty acids in muscle, bone, heart, liver, and intestine of blue back fishes. Arachidonic acid was detected richer in intestines than other tissues of blue back fishes. The concentrations were between 4.45 and 5.62 µg/g tissue weight. EPA and DHA are also detected richer in intestines of blue back fishes. The concentrations were between 75.95 and 358.04 µg/g, and 203.09 and 464.88 µg/g, respectively. Especially, mackerel intestine contained the highest levels of both EPA and DHA. 5,6-DiHETE was present in greater amount in livers and intestines of blue back fishes. The livers contained 118.98 to 476.11 ng/g, whereas intestines contained 156.14 to 970.22 ng/g of 5,6-DiHETE. Of interest, sardine intestine contained much higher level of 5,6-DiHETE than the other fish tissues. These results suggest that visceral organs of blue back fishes, remarkably sardine intestine, can be a good source of 5,6-DiHETE. PRACTICAL APPLICATION: A novel anti-inflammatory lipid, 5,6-DiHETE, was detected in each tissues of blue back fishes. Especially their intestines contain the highest concentration of this lipid.
