Shen N, Ba Q, Lu Y. Causal Relationships between Polyunsaturated Fatty Acids and Colon Polyps: A Two-Sample Mendelian Randomization Study. Nutrients 2024; 16:2033. [PMID: 38999781 PMCID: PMC11243184 DOI: 10.3390/nu16132033] [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: 05/27/2024] [Revised: 06/14/2024] [Accepted: 06/24/2024] [Indexed: 07/14/2024] Open
Abstract
BACKGROUND Epidemiological studies have shown that fatty acids, especially polyunsaturated fatty acids (PUFAs), influence colorectal carcinogenesis. Colon polyps, particularly those identified as precancerous, are a frequently encountered phenomenon associated with PUFAs. However, the results are inconsistent. Therefore, we investigated the effect of PUFAs on colon polyps in individuals of European ancestry. METHODS Single nucleotide polymorphisms correlating with PUFAs and colon polyps were derived from extensive genome-wide association studies, encompassing a discovery cohort of 135,006 samples and a corresponding validation set with 114,999 samples. Causality was assessed by employing a range of techniques, such as inverse variance weighted (IVW), weighted median, MR-Egger, and simple and weighted modes. The analysis was complemented with sensitivity checks using leave-one-out and heterogeneity evaluation through MR-IVW and Cochran's Q. RESULTS A thorough analysis was performed to examine the causal effects of PUFAs on the development of colon polyps. The findings indicated that levels of Omega-3 fatty acids (OR = 1.0014, 95% CI 1.0004-1.0024, p = 0.004), the ratio of Docosahexaenoic acid (DHA)/total fatty acids (FAs) (DHA/totalFA; OR = 1.0015, 95% CI 1.0002-1.0028, p = 0.023), and the ratio of Omega-3/totalFA (Omega-3/totalFA; OR = 1.0013, 95% CI 1.0003-1.0022, p = 0.010) were identified as biomarkers associated with an increased risk of colon polyps. Conversely, the ratio of Omega-6/Omega-3 (OR = 0.9986, 95% CI 0.9976-0.9995, p = 0.003) and the ratio of Linoleic acid (LA)/totalFA (LA/totalFA; OR = 0.9981, 95% CI 0.9962-0.9999, p = 0.044) were negatively associated with susceptibility to colon polyps. The MR-Egger and MR-IVW analysis revealed that pleiotropy and heterogeneity did not significantly impact the outcomes. CONCLUSION This study has uncovered a possible adverse effect of PUFAs, notably Omega-3, on the formation of colon polyps. Elevated Omega-3 levels were correlated with a heightened risk of colon polyps.

Network pharmacology combined with an experimental validation study to reveal the effect and mechanism of Lonicera japonica Thunb. extracts against immunomodulation. J Food Sci 2024; 89:3829-3846. [PMID: 38745368 DOI: 10.1111/1750-3841.17074] [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: 11/29/2023] [Revised: 03/25/2024] [Accepted: 03/27/2024] [Indexed: 05/16/2024]
Abstract
Lonicera japonica Thunb. (LJT) is known for its valuable medicinal properties that highlight its potential application in the pharmaceutical and health food industry. We predict that LJT polyphenols by network pharmacology may be involved in immunomodulation, and the study of LJT polyphenols regulating immunity is still insufficient; therefore, we experimentally found that LJT enhances immunity by promoting the proliferation and phagocytic activity of RAW246.7 cells. A model of an immunosuppressed mouse was constructed using cyclophosphamide-induced, and LJT was extracted for the intervention. We found that LJT restored immune homeostasis in immune deficiency mice by inhibiting the abnormal apoptosis in lymphocytes, enhancing natural killer cell cytotoxicity, promoting T lymphocyte proliferation, and increasing the CD4+ and CD8+ T lymphocytes in quantity. Moreover, LJT treatment modulates immunity by significantly downregulating lipopolysaccharide-induced inflammation and oxidative stress levels. We verified the immunomodulatory function of LJT through both cell and animal experiments. The combination of potential-protein interactions and molecular docking later revealed that LJT polyphenols were associated with immunomodulatory effects on MAPK1; together, LJT intervention significantly modulates the immune, with the activation of MAPK1 as the underlying mechanism of action, which provided evidence for the utilization of LJT as a nutraceutical in immune function.

Abstract
A lipid extract was obtained from eggs of the sailfin sandfish, Arctoscopus japonicus. Immunostimulatory effects of A. japonicus lipids incorporated with PEG6000 (AJ-PEG) on immunosuppressed mice treated with cyclophosphamide (CY) were investigated. AJ-PEG was administered orally to mice at different concentrations of 25 to 100 mg/kg body weight (BW). CY was injected to mice intraperitoneally at 80 mg/kg BW. Administration of AJ-PEG significantly increased the spleen index of CY-treated mice. AJ-PEG also stimulated the proliferation of splenic lymphocytes and natural killer (NK) activity. Immune-associated cytokines such as IL-1β, IL-2, IL-4, IL-6, TNF-α, and IFN-γ as well as TLR4 were overexpressed in splenic lymphocytes. Furthermore, AJ-PEG significantly increased splenic CD4+ and CD8+ T lymphocytes. In peritoneal macrophages, AJ-PEG administration improved proliferation, nitric oxide (NO) production, and phagocytosis. It also upregulated iNOS, COX-2, IL-1β, IL-6, and TNF-α expression. Taken together, these results suggest that AJ-PEG can be used in animal models with immunosuppressive conditions as a potent immunomodulatory agent.

Abstract
Docosahexaenoic acid (DHA) is a polyunsaturated fatty acid that benefits the prevention of chronic diseases. Due to its high unsaturation, DHA is vulnerable to free radical oxidation, resulting in several unfavorable effects, including producing hazardous metabolites. However, in vitro and in vivo investigations suggest that the relationship between the chemical structure of DHA and its susceptibility to oxidation may not be as clear-cut as previously thought. Organisms have developed a balanced system of antioxidants to counteract the overproduction of oxidants, and the nuclear factor erythroid 2-related factor 2 (Nrf2) is the key transcription factor identified for transmitting the inducer signal to the antioxidant response element. Thus, DHA might preserve the cellular redox status promoting the transcriptional regulation of cellular antioxidants through Nrf2 activation. Here, we systematically summarize the research on the possible role of DHA in controlling cellular antioxidant enzymes. After the screening process, 43 records were selected and included in this review. Specifically, 29 studies related to the effects of DHA in cell cultures and 15 studies concerned the effects of consumption or treatment with DHA in animal. Despite DHA's promising and encouraging effects at modulating the cellular antioxidant response in vitro/in vivo, some differences observed among the reviewed studies may be accounted for by the different experimental conditions adopted, including the time of supplementation/treatment, DHA concentration, and cell culture/tissue model. Moreover, this review offers potential molecular explanations for how DHA controls cellular antioxidant defenses, including involvement of transcription factors and the redox signaling pathway.

Abstract
Cholesterol-enriched domains are nowadays proposed to contribute to cancer cell proliferation, survival, death and invasion, with important implications in tumor progression. They could therefore represent promising targets for new anticancer treatment. However, although diverse strategies have been developed over the years from directly targeting cholesterol membrane content/distribution to adjusting sterol intake, all approaches present more or less substantial limitations. Those data emphasize the need to optimize current strategies, to develop new specific cholesterol-targeting anticancer drugs and/or to combine them with additional strategies targeting other lipids than cholesterol. Those objectives can only be achieved if we first decipher (i) the mechanisms that govern the formation and deformation of the different types of cholesterol-enriched domains and their interplay in healthy cells; (ii) the mechanisms behind domain deregulation in cancer; (iii) the potential generalization of observations in different types of cancer; and (iv) the specificity of some alterations in cancer vs. non-cancer cells as promising strategy for anticancer therapy. In this review, we will discuss the current knowledge on the homeostasis, roles and membrane distribution of cholesterol in non-tumorigenic cells. We will then integrate documented alterations of cholesterol distribution in domains at the surface of cancer cells and the mechanisms behind their contribution in cancer processes. We shall finally provide an overview on the potential strategies developed to target those cholesterol-enriched domains in cancer therapy.

Abstract
Topical eye drops still face challenges of low-drug treatment effects and frequent dosing in ophthalmic applications due to the low preocular retention rate and low transcorneal permeability. Thus, we designed and synthesized a phenylboronic acid conjugated chitosan oligosaccharide-vitamin E copolymer (PBA-CS-VE) for use in mucoadhesive voriconazole (VRC)-loaded nanomicelles for fungal keratitis. In vitro mucin binding and ex vivo eyeball adhesion tests show that the copolymer has strong mucoadhesion. The transportation of coumarin-6 (C6) across a monolayer of HCE-T cells and 3D cell spheroids confirm the strong corneal penetration ability of PBA-CS-VE. The mechanism of promoting corneal penetration was studied in terms of intracellular calcium-ion concentration, cell membrane potential, cell membrane fluidity, and the tight junctions of cells. The pharmacokinetics in the aqueous humor were examined to evaluate the ability of nanomicelles in promoting corneal penetration and prolonging ocular retention. VRC-loaded PBA-CS-VE nanomicelles (PBA-CS-VE-VRC) yielded a very favorable therapeutic effect on a rabbit model of fungal keratitis in vivo as compared to the free drug. Overall, the results indicate that PBA-CS-VE nanomicelles are a mucoadhesive candidate with enhanced transcorneal permeability and prolonged preocular retention for efficient delivery of topical ocular drugs. STATEMENT OF SIGNIFICANCE: Although eye drops are widely used in ocular drug delivery, the disadvantages such as short retention time and weak corneal penetrating ability still seriously affect the therapeutic effect of the drug. Therefore, the mucoadhesive carrier seems to be an interesting strategy for ocular drug delivery. Herein, a novel phenylboronic acid conjugated chitosan oligosaccharide-vitamin E copolymer was designed and constructed as mucoadhesive nanomicelles loaded with voriconazole for fungal keratitis. These nanomicelles were able to improve the in vitro mucin binding and to prolong the residence time of the drug on the surface of the eyeball. Moreover, the nanomicelles exhibited an enhanced drug permeability in cell monolayer models and 3D cell culture models. This work provides a promising ocular drug delivery system.

Abstract
Docosahexaenoic acid (DHA) has been studied for many years owing to its protective effect on the decline in brain function. DHA intake reduces the risk of Alzheimer's disease (AD) and decreases amyloid deposition; however, the underlying molecular mechanism has not been completed elucidated. In this study, the effect of DHA on the cognitive function of amyloid precursor protein (APP)/PS1 in wild-type mice and its related mechanism were investigated. Results from the Morris water maze test showed that DHA improved learning and memory function in mice. Moreover, DHA reduced neuronal damage in mice brains, as determined using Nissl staining. Unsaturated fatty acid levels in the brain of mice increased (p < 0.01) after DHA administration and saturated fatty acid levels decreased (p < 0.01). The deposition of amyloid-beta (Aβ) plaques and tau protein neurofibrillary tangles was significantly inhibited. The mechanism of action of DHA was attributed to the upregulation of the expression of β-secretase (BACE)2, which competed with BACE1 to cleave APP, thus decreasing the production of extracellular Aβ fragments (p < 0.01). The expression level of insulin-degrading enzyme was not significantly different. The expression of N-methyl-D-aspartate receptors was further downregulated and the phosphorylation of glycogen synthase kinase-3β and tau protein was inhibited (p < 0.01). These data indicated that DHA could protect cognitive function in mice by reducing Aβ plaque formation and decreasing tau phosphorylation levels.

Abstract
Matrix-assisted laser desorption/ionization-based mass spectrometry imaging (MSI) of separated lipids on thin-layer chromatography (TLC) plates or followed by blotted hydrophilic polyvinylidene fluoride (PVDF) membranes has become a powerful tool in lipidomic analyses. However, background peaks in MS spectra often cover lipid peaks in a low amount/ionization effect; consequently, only low intensities/resolutions MSI are obtained. To address the aforementioned problem, we attempted 1,2-dichloroethane pre-washing of TLC plates before development and found that backgrounds could successfully be removed from the TLC plate or PVDF membrane.

Abstract
Docosahexaenoic acid (DHA) has attracted plenty of interest in the prevention of neurodegenerative diseases. Although the beneficial effects of DHA on the central nervous system function are recognized, more information on the molecular mechanisms involved in its neuroprotective effects is required. The present study aimed to evaluate the effects of DHA on the function of mitochondria, neurite growth-related proteins signaling pathway, and neural signal transmission. In this study, PC12 cells were treated with H2O2 (400 μM) to establish an oxidative damage model. Results showed that DHA improved the viability and morphology of PC12 cells. DHA significantly increased the antioxidant capacity, mitochondrial membrane potential, and activity of ATPase in the cells. Furthermore, the phosphorylation levels of tyrosine kinase receptor (BTrkB), phospholipase C-γ1 (PLCγ1), calcium/calmodulin-dependent protein kinase II (CaMKII), extracellular regulated protein kinases 1/2 (ERK1/2), and cAMP-response element-binding protein (CREB) were upregulated by DHA. The damage on F-actin induced by H2O2 was reversed by DHA, indicating that DHA could protect neurite outgrowth. In addition, DHA increased the content of acetylcholine and γ-aminobutyric acid while decreasing glutamic acid. These results revealed that DHA could protect PC12 cells from damage induced by H2O2 through the TrkB-ERK1/2-CREB pathway.

Abstract
As a membrane protein, the activity of angiotensin I-converting enzyme (ACE) can be modulated via regulation of its localization in the cell membrane with food-derived peptides. This study aimed to explore the effect of egg white peptides on the cell membrane localization and activity of ACE in human umbilical vein endothelial cells. ACE activity was found to be related to lipid rafts by using methyl-β-cyclodextrin (MβCD). QVPLW and LCAY can inhibit ACE activity by preventing ACE recruitment into lipid rafts, with in situ IC50 values of 238.46 ± 11.35 μM and 31.55 ± 2.64 μM in the control groups, as well as 45.43 ± 6.15 μM and 34.63 ± 1.59 μM in the MβCD groups, respectively. QVPLW and LCAY may alter the cell membrane properties, including the fluidity, potential, and permeability, and eventually promote the transposition of ACE.

The current study investigated the immunomodulating and osteoblast differentiation potential of the natural compounds from Leea macrophylla (LMN). Immunomodulatory effects have been investigated by the phagocytosis of Candida albicans using polymorphonuclear neutrophil cells in the in vitro slide method. A bioactivity-guided fractionation technique was used to evaluate the stimulating effect of L. macrophylla methanol extract on osteoblast differentiation using mouse osteoblastic cells. A low dose of LMN was found to stimulate the phagocytic effect better than a higher dose. The natural compounds from L. macrophylla have significantly increased alkaline phosphatase (ALP) and osteocalcin activities. The LMN promoted the osteoblast differentiation through upregulation of ALP, osteocalcin, and type 1 collagen in a dose-dependent manner. These natural compounds also upregulated ALP, osteocalcin, and type 1 collagen gene expressions. The data suggest that LMN has potential anabolic sequel on bone formation and osteoblast differentiation.

Effects of Varying Dietary Docosahexaenoic, Eicosapentaenoic, Linoleic, and α-Linolenic Acid Levels on Fatty Acid Composition of Phospholipids and Neutral Lipids in the Liver of Atlantic Salmon, Salmo salar.

Abstract
Fish oil, the most abundant natural source of docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA), is a limited resource; however, terrestrial oils are used as an alternative in fish nutrition. The liver of Atlantic salmon is able to synthesize these two long-chain n-3 polyunsaturated fatty acids (n-3LC-PUFAs) from α-linolenic acid (ALA), but the dietary levels of EPA + DHA and the ratios of linoleic acid (LNA) to ALA may affect its abilities. Feeding Atlantic salmon four experimental diets containing EPA + DHA at 0.3 and 1.0% of dietary levels accompanied with high and low LNA/ALA ratios showed that low LNA/ALA ratios increased the proportions of EPA + DHA in phospholipids (PLs) and neutral lipids (NLs). The pattern of PL-to-NL ratios of n-3 LC-PUFA proportions matched the saw tooth pattern of LNA/ALA ratios in diets. Overall, when fish oil is removed from salmon diets, the dietary LNA/ALA ratio must be reduced to stimulate biosynthesis of n-3 LC-PUFAs in the liver.

Abstract
Modulation of membrane lipid composition and organization is currently developing as an effective therapeutic strategy against a wide range of diseases, including cancer. This field, known as membrane-lipid therapy, has risen from new discoveries on the complex organization of lipids and between lipids and proteins in the plasma membranes. Membrane microdomains present in the membrane of all eukaryotic cells, known as lipid rafts, have been recognized as an important concentrating platform for protein receptors involved in the regulation of intracellular signaling, apoptosis, redox balance and immune response. The difference in lipid composition between the cellular membranes of healthy cells and tumor cells allows for the development of novel therapies based on targeting membrane lipids in cancer cells to increase sensitivity to chemotherapeutic agents and consequently defeat multidrug resistance. In the current manuscript strategies based on influencing cholesterol/sphingolipids content will be presented together with innovative ones, more focused in changing biophysical properties of the membrane bilayer without affecting the composition of its constituents.
