Conventional treatment methods, including chemotherapy, radiation therapy, surgery, and hormonal therapy, often encounter significant challenges such as systemic toxicity and diminished efficacy, particularly in the advanced stages of the disease. Treatment of prostate cancer remains a formidable challenge because of the poor water solubility of many chemotherapeutic agents, which severely limits their bioavailability. However, the rise of targeted therapies has catalyzed the development of innovative drug delivery systems designed to enhance the bioavailability and precision of therapeutic agents. Solid lipid nanoparticles (SLNs) are a promising solution that can effectively encapsulate chemotherapeutic agents and genetic materials. Their unique attributes, such as biocompatibility, controlled release profile, and customizable surface properties, make them advantageous alternatives to conventional treatment strategies, effectively addressing the inherent limitations of prostate cancer therapy.</div></div><div><h3>Methods</h3><div>To provide the context, relevant publications were searched on Google Scholar, PubMed, Science Direct, Dimension AI, and EBSCO Host using specific keywords such as controlled drug release, cationic surfactants, drug delivery, drug loading, drug encapsulation lipid, prostate cancer, surface modification, solid lipid nanoparticles (SLNs), tumor microenvironment, to list a few.

However, previous evidence suggests that OPFRs may pose potential respiratory health risks, including airway hyperresponsiveness, impaired lung function, and potential carcinogenic effects. This study evaluated the effects of seven OPFRs—TBOEP, TPhP, EHDPhP, TDCPP, TEHP, TCP, and TCEP—on the phenotype and lipidomic profile of A549 lung cancer cells, using both 2D and 3D culture models. TDCPP and TPhP significantly reduced cell viability, while TBOEP caused the highest increase in reactive oxygen species (ROS), followed by TPhP, TDCPP, and TCP. Moreover, TPhP, TDCPP, EHDPhP, and TBOEP also elevated the levels of pro-inflammatory cytokine interleukin-8 (IL-8). The lipidomic analysis of 3D cell spheroids exposed to OPFRs for 72 h revealed distinct lipid profiles for each compound at low (25 μM) and high (100 μM) doses. Common features were observed, particularly at high doses, including significant increases in triacylglycerol, diacylglycerol, ceramide, ether-linked phosphatidylethanolamine, and phosphatidylinositol species. These effects were generally more pronounced for TPhP, TDCPP, EHDPhP, TCP, and TBOEP. The accumulation of triglycerides, indicative of augmented energy storage, was confirmed by the visualization of lipid droplets formation. Results suggest disruptions in key toxicological pathways, including oxidative stress, inflammatory signaling (IL-8 upregulation), and apoptosis (ceramide accumulation), all implicated in lung diseases, such as COPD and fibrosis. These results provide a basis for assessing the health risks associated with OPFRs, highlighting the need for further research on chronic low-dose exposure levels.</div></div>","PeriodicalId":275,"journal":{"name":"Chemistry and Physics of Lipids","volume":"270 ","pages":"Article 105508"},"PeriodicalIF":3.4,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144191319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating lipidomics and inflammatories data with POI from Genome-wide association study (GWAS) and FinnGen, we identified 18 causally significant lipids, including risk-elevating phosphatidylcholines and sphingomyelins, and protective triglycerides. Methodologically, we innovatively applied Bayesian Weighted Mendelian Randomization (BWMR) to confirm the robustness of causal estimates, addressing limitations of conventional MR in pleiotropy-prone metabolic networks. Biologically, we discovered IL-10 mediates 7.02–9.03 % of the effects of sphingomyelin (d40:2) and (d42:2) on POI, reconciling lipid-driven inflammation with ovarian aging—a mechanism previously unreported. Sensitivity analyses confirmed no horizontal pleiotropy (p &gt; 0.05). This work establishes three advances: (1) First MR evidence linking specific lipid subclasses (not just broad categories) to POI; (2) Identification of IL-10 as a novel inflammatory mediator bridging sphingolipids and POI pathogenesis; (3) A validated framework combining MVMR and mediation analysis to disentangle direct/indirect effects in reproductive aging.

In this review, we analyze the impact of disruption in this equilibrium on physiological aging and the onset of pathological conditions. Alzheimer´s disease (AD) is a multifactorial neurodegenerative disorder in the elderly, characterized by the increased presence of the Aβ peptide, which supports the amyloid hypothesis of the disease. However, AD also involves a progressive loss of cholinergic innervation, leading to the cholinergic hypothesis of the disease. Nicotinic acetylcholine receptors (nAChRs) are transmembrane proteins, and Aβ peptides, their oligomeric and fibrillar species, which increase in hydrophobicity as they develop, interact with membranes. Therefore, a membrane hypothesis of the disease emerges as a bridge between the other two. Here, we discuss the impact of the membrane environment, through direct or indirect mechanisms, on cholinergic signaling and Aβ formation and subsequent incorporation into the membrane, with a special focus on the crucial role of cholesterol in these processes.</div></div>","PeriodicalId":275,"journal":{"name":"Chemistry and Physics of Lipids","volume":"269 ","pages":"Article 105484"},"PeriodicalIF":3.4,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143727188","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In absence of lipids, pure form of both Aβ(1 −42) and Aβ(42 −1) form insoluble monolayer films without appreciable fibril-like structures despite the high interfacial confinement.

The above structures are clearly visualized at the interface by using Brewster Angle Microscopy. In the same way, the isolate fibers and oligomers become Thioflavin T positive when they are observed by Fluorescence Microscopy. Thus, we attributed an amyloid behavior at the air/water interface that was also evidenced by Scanning Electron Microscopy when the mixed film was transferred to mica support. Changes from an exclusive β-sheet in pure peptide to a notable increase in α-helix/unordered conformations were induced by the presence of the lipid keeping with fibril-like structures.

This process depends both on the characteristics of the detergent and properties of the membrane. Here we investigate the interaction of eight detergents with very distinct physicochemical features with model membranes in different biologically relevant phases. The detergents chosen were the non-ionic Triton X-100, Triton X-165, C10E5, octyl glucopyranoside (OG) and dodecyl maltoside (DDM) and the ionic sodium dodecyl sulfate (SDS), cetyl trimethyl ammonium bromide (CTAB) and Chaps. Three lipid compositions were explored: pure palmitoyl oleoyl phosphatidylcholine (POPC), in the liquid-disordered (Ld) phase, sphingomyelin (SM)/cholesterol 7:3 (chol) in the liquid-ordered (Lo) phase and the biomimetic POPC/SM/chol 2:1:2, which might exhibit Lo/Ld phase separation. Turbidity measurements of small liposomes were performed along the titration with the detergents to obtain the overall solubilization profiles and optical microscopy of giant unilamellar vesicles (GUVs) was used to reveal the mechanism of interaction of the detergents. The presence of cholesterol renders the membranes partly/fully insoluble in all detergents, and the charged detergents are the least effective to solubilize POPC. The non-ionic detergents, with exception of DDM, with the bulkiest headgroup, caused a substantial increase in surface area of POPC, which was quantified directly on single GUVs. The other detergents induced mainly vesicle burst. Detergents that caused some increase in area induced Lo/Ld phase separation in the ternary mixture, with preferential solubilization of the latter.
