[PMID: 37012890 DOI: 10.1016/j.intimp.2023.109937] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2022] [Accepted: 02/22/2023] [Indexed: 03/11/2023]
Abstract
BACKGROUND Previous studies found Propionibacterium acnes (P. acnes) has a strong association with acne inflammation and cell pyroptosis. Because of the various side effects of current acne medicines, it is important to explore alternative drugs with anti-inflammatory activity against P. acnes. we explored the effect of Lutein on P. acnes-induced cell pyroptosis and accelerated the recovery of acne inflammation in vitro and vivo. METHODS Lutein was utilized to expose HaCaT keratinocytes, then we reassessed the effect of Lutein on the cell apoptosis, pyroptotic-associated inflammatory factors and catabolic enzymes in heat-killed P. acnes-treated HaCaT cells. Next, living P. acnes was intradermally injected into the right ears of ICR mice to induce mice with acne inflammation, and the effect of Lutein on living P. acnes-induced inflammation was investigated. Moreover, we explored the mechanism of Lutein on TLR4/NLRP3/Caspase-1 pathways by ELISA, immunofluorescence microscopy, and western blot assay. RESULTS Heat-killed P. acnes triggered remarkable cell pyroptosis, pyroptotic inflammatory factors and catabolic enzymes in HaCaT cells, including up-regulating interleukin (IL)-1β, IL-18, TNF-α, MMP3, MMP13, ADAMTS4, and ADAMTS5, TLR4, NLRP3, caspase-1, and the ratio of gasdermin D to cleaved gasdermin D, whereas these effects were suppressed by Lutein. In addition, Lutein effectively improved ear redness, swelling, and the expression of TLR4, IL-1β and TNF-α in vivo. Finally, NLRP3 activator (nigericin) increased caspase-1, IL-1β and IL-18 level, while TLR4 inhibitor (TAK-242) significantly blocked this effect in heat-killed P. acnes-treated cells. CONCLUSIONS Lutein attenuated P. acnes-caused pyroptosis of HaCaTs and the subsequent acne inflammation via the TLR4/NLRP3/Caspase-1 pathway.

Wan P, Cai B, Chen H, Chen D, Zhao X, Yuan H, Huang J, Chen X, Luo L, Pan J. Antidiabetic effects of protein hydrolysates from Trachinotus ovatus and identification and screening of peptides with α-amylase and DPP-IV inhibitory activities. Curr Res Food Sci 2023; 6:100446. [PMID: 36816000 PMCID: PMC9932700 DOI: 10.1016/j.crfs.2023.100446] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 01/04/2023] [Accepted: 01/13/2023] [Indexed: 01/15/2023] Open
Abstract
In the present study, the antidiabetic properties of Trachinotus ovatus protein hydrolysates (TOH) in streptozotocin-induced diabetic mice were investigated, and peptides with α-amylase (AAM) and dipeptidyl peptidase IV (DPP-IV) inhibitory activities were identified and screened. The results showed that TOH alleviated body weight loss, polyphagia, blood glucose elevation and insulin secretion decline in diabetic mice. After 4 weeks of TOH administration, random blood glucose (RBG) decreased significantly. The TOH groups showed a dose-dependent reduction in fasting blood glucose (FBG), especially in the high-dose TOH group, which reduced FBG by 58% versus the effect of metformin. Moreover, TOH exerted a remarkable protective effect on hepatorenal function, as evidenced by increased superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) and decreased serum urea levels. Histopathological studies confirmed that TOH can significantly protect the kidney and pancreas from histological changes, which was of great benefit for ensuring the normal secretion of insulin and preventing the occurrence of complications such as diabetic nephropathy. Two fractions with higher inhibitory activity against AAM and DPP-IV, F4 and F6, were obtained from the ultrafiltration of TOH-2 (≤3 kDa). A total of 19 potentially active peptides from F4 and 3 potentially active peptides from F6 were screened by LC‒MS/MS combined with bioinformatic analysis. These peptides are small molecular peptides composed of 2-6 amino acids, rich in characteristic amino acids such as proline, arginine, phenylalanine and asparagine, and contain high proportions of peptides (68% for F4, 67% for F6) with hydrophobicity ≥50%. They offer potent antidiabetic potential and could potentially bind to the active sites in the internal cavities of the target enzymes AAM and DPP-IV. In summary, this study revealed for the first time the antidiabetic effects of protein hydrolysates of Trachinotus ovatus and their derived peptides, which are promising natural ingredients with the potential to be used for the treatment or prevention of diabetes.

Comparison of the Retention Rates of Synthetic and Natural Astaxanthin in Feeds and Their Effects on Pigmentation, Growth, and Health in Rainbow Trout ( Oncorhynchus mykiss). Antioxidants (Basel) 2022; 11:antiox11122473. [PMID: 36552680 PMCID: PMC9774906 DOI: 10.3390/antiox11122473] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 12/09/2022] [Accepted: 12/13/2022] [Indexed: 12/23/2022] Open
Abstract
The coloring efficiency and physiological function of astaxanthin in fish vary with its regions. The aim of this study was to compare the retention rates of dietary astaxanthin from different sources and its effects on growth, pigmentation, and physiological function in Oncorhynchus mykiss. Fish were fed astaxanthin-supplemented diets (LP: 0.1% Lucantin® Pink CWD; CP: 0.1% Carophyll® Pink; EP: 0.1% Essention® Pink; PR: 1% Phaffia rhodozyma; HP: 1% Haematococcus pluvialis), or a diet without astaxanthin supplementation, for 56 days. Dietary astaxanthin enhanced pigmentation as well as the growth of the fish. The intestinal morphology of fish was improved, and the crude protein content of dorsal muscle significantly increased in fish fed with astaxanthin. Moreover, astaxanthin led to a decrease in total cholesterol levels and alanine aminotransferase and aspartate aminotransferase activity in plasma. Fish fed on the CP diet also produced the highest level of umami amino acids (aspartic acid and glutamic acid). Regarding antioxidant capacity, astaxanthin increased Nrf2/HO-1 signaling and antioxidant enzyme activity. Innate immune responses, including lysozyme and complement systems, were also stimulated by astaxanthin. Lucantin® Pink CWD had the highest stability in feed and achieved the best pigmentation, Essention® Pink performed best in growth promotion and Carophyll® Pink resulted in the best flesh quality. H. pluvialis was the astaxanthin source for achieving the best antioxidant properties and immunity of O. mykiss.

Effects of exogenous taurine supplementation on the growth, antioxidant capacity, intestine immunity, and resistance against Streptococcus agalactiae in juvenile golden pompano (Trachinotus ovatus) fed with a low-fishmeal diet. Front Immunol 2022; 13:1036821. [DOI: 10.3389/fimmu.2022.1036821] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Accepted: 09/28/2022] [Indexed: 11/13/2022] Open
Abstract
Taurine has various biological functions in fish, playing an essential role in growth, resistance to oxidative stress, and intestine immunity. Here, we evaluated the effects of exogenous taurine added to low-fishmeal diets on the growth, anti-oxidative stress, intestine immunity, and Streptococcus agalactiae resistance in juvenile golden pompano (Trachinotus ovatus). Our study showed that exogenous taurine supplementation of 1.2% (T3 group) greatly enhanced the weight gain rate and specific growth rate (SGR) of juvenile golden pompano, significantly upregulating growth-related factor expression in the brain and liver, as well as the levels of growth-related parameters in the serum. Polynomial regression analysis using SGR estimated the optimal dietary taurine level for golden pompano at 1.18%. Moderate exogenous taurine also increased the muscular thickness and villus length within the intestine, maintained intestinal physical barrier stability, activated the Nrf2/Keap-1/HO-1 signaling pathway, increased intestinal antioxidant enzyme gene expression and antioxidant enzyme activity in the serum, and upregulated immunoglobulin and complement levels in parallel with declining reactive oxygen species (ROS) levels in the serum. Antioxidant factor expression was also upregulated in the intestine. Furthermore, supplementation suppressed NF-κB signaling and intestinal pro-inflammatory cytokine gene expression, increased anti-inflammatory cytokine gene expression, and improved intestine immunity. Finally, taurine supplementation improved the survival rate of golden pompano challenged with S. agalactiae. Overall, our findings provide additional information and support for the rational use of taurine in healthy aquatic animal farming.
