Abstract
Cellular membranes serve as an epicentre combining extracellular and cytosolic components with membranous effectors, which together support numerous fundamental cellular signalling pathways that mediate biological responses. To execute their functions, membrane proteins, lipids and carbohydrates arrange, in a highly coordinated manner, into well-defined assemblies displaying diverse biological and biophysical characteristics that modulate several signalling events. The loss of membrane homeostasis can trigger oncogenic signalling. More recently, it has been documented that select membrane active dietaries (MADs) can reshape biological membranes and subsequently decrease cancer risk. In this review, we emphasize the significance of membrane domain structure, organization and their signalling functionalities as well as how loss of membrane homeostasis can steer aberrant signalling. Moreover, we describe in detail the complexities associated with the examination of these membrane domains and their association with cancer. Finally, we summarize the current literature on MADs and their effects on cellular membranes, including various mechanisms of dietary chemoprevention/interception and the functional links between nutritional bioactives, membrane homeostasis and cancer biology.

Abstract
Although the role of the Wnt pathway in colon carcinogenesis has been described previously, it has been recently demonstrated that Wnt signaling originates from highly dynamic nano-assemblies at the plasma membrane. However, little is known regarding the role of oncogenic APC in reshaping Wnt nanodomains. This is noteworthy, because oncogenic APC does not act autonomously and requires activation of Wnt effectors upstream of APC to drive aberrant Wnt signaling. Here, we demonstrate the role of oncogenic APC in increasing plasma membrane free cholesterol and rigidity, thereby modulating Wnt signaling hubs. This results in an overactivation of Wnt signaling in the colon. Finally, using the Drosophila sterol auxotroph model, we demonstrate the unique ability of exogenous free cholesterol to disrupt plasma membrane homeostasis and drive Wnt signaling in a wildtype APC background. Collectively, these findings provide a link between oncogenic APC, loss of plasma membrane homeostasis and CRC development.

Abstract
Abstract
Colorectal cancer (CRC) is the 3rd most common type of cancer in the U.S., and it is estimated it will account for an alarming 151,030 (8%) of new total cancer cases and 52,580 (9%) of total cancer deaths in 2022. Remarkably, dysregulation of the Wnt signaling pathway has been linked to ~90% of all colorectal cancer (CRC) cases. The vast majority (>80%) of sporadic CRC cases display mutations in Adenomatous Polyposis Coli (APC), a central Wnt signaling regulator. Loss of APC function causes aberrant stabilization of β-catenin (βcat), a crucial step in CRC initiation. Notably, attempts towards “drugging” this pathway still poses multiple hurdles due to poor tumor cell targeting, negative side effects associated with required long-term treatments and poorly understood mechanisms of action. Consequently, there is an urgent need to gather additional mechanistic insights associated with the Wnt pathway to develop novel therapeutic approaches. With respect to Wnt biology, two key plasma membrane receptors, LRP5/6 and Frizzled (Fzd) require lipid raft localization and nanoclustering for efficient signaling. Interestingly, various effectors that disrupt raft dynamics, alter LRP5/6-Fzd clustering, leading to reduced βcat stabilization. Thus, we examined the effect of mutant APC (mAPC) on plasma membrane lipid/protein-mediated interactions of Wnt-associated effectors in a CRC mouse model, human mAPC-expressing organoids and cell lines, and Drosophila. We show for the first time that mAPC significantly increased the levels of plasma membrane free cholesterol, a major component of lipid rafts known to selectively activate canonical Wnt signaling, in the intestinal epithelium including Lgr5+ colonic stem cells. Moreover, this change in plasma membrane cholesterol was associated with alterations in colonocyte membrane rigidity and raft organization. We subsequently examined the effect of mAPC on the interactions between Wnt signaling receptors/effectors in mAPC-expressing cell lines. mAPC significantly increased LRP6 and Fzd7 homo-clustering and LRP6-Fzd7 hetero-clustering as well as their interactions with key lipids, e.g., PIP2, resulting in the enhancement of Wnt signaling activation. Interestingly, the effects of mAPC were recapitulated by the addition of exogenous cholesterol to wild type colonocytes. Finally, we demonstrate that n-3 polyunsaturated fatty acids (n3-PUFA), i.e., DHA and EPA, reduces mAPC-driven colonic polyp formation in mice in part by reducing plasma membrane cholesterol, rigidity and LRP6-Fzd7 clustering in colonocytes. Collectively, these findings indicate that mAPC can directly perturb lipid homeostasis in the colon, thereby altering raft stability, LRP6-Fzd7 membrane nanoclusters and downstream Wnt signaling and supports the feasibility of using membrane therapy, i.e., dietary/drug-related strategies to target plasma membrane lipid composition, to reduce Wnt signaling and cancer risk.

Abstract
Despite strong evidence supporting the cellular interplay between haemostasis and innate immunity, humoral connections between blood coagulation and the behavior of inflammatory macrophages are not well understood. In this study, we investigated changes in gene expression of selected cytokines and chemokines and their secretion profiles following thrombin stimulation of murine macrophages. Thrombin promoted differentiation of macrophages into an M1-like phenotype that was associated with the expression of classical pro-inflammatory markers. The cellular actions of thrombin on macrophages were mediated in part by protease-activated receptor-1 (PAR-1) and were dependent on phosphoinositide 3-kinase/AKT and nuclear factor-κB. Moreover, heat-denatured thrombin stimulated the secretion of some pro-inflammatory mediators to the same magnitude indicating that different receptors transmit cellular signals of enzymatically active thrombin and nonactive thrombin, the latter remaining so far undefined. Finally, pretreatment of macrophages with thrombin resulted in tolerance against secondary stimulation by lipopolysaccharide with regard to expression of tumor necrosis factor-α. These results provide new insights into the molecular link between the key enzyme of haemostasis and innate immunity responses.

Abstract
Reverse cholesterol transport (RCT) is considered as the most important antiatherogenic role of high-density lipoproteins (HDL), but interventions based on RCT have failed to reduce the risk of coronary heart disease. In contrast to RCT, important evidence suggests that HDL deliver lipids to peripheral cells. Therefore, in this paper, we investigated whether HDL could improve endothelial function by delivering lipids to the cells. Internalization kinetics using cholesterol and apolipoprotein (apo) AI fluorescent double-labeled reconstituted HDL (rHDL), and human dermal microvascular endothelial cells-1 (HMEC-1) showed a fast cholesterol influx (10 min) and a slower HDL protein internalization as determined by confocal microscopy and flow cytometry. Sphingomyelin kinetics overlapped that of apo AI, indicating that only cholesterol became dissociated from rHDL during internalization. rHDL apo AI internalization was scavenger receptor class B type I (SR-BI)-dependent, whereas HDL cholesterol influx was independent of SR-BI and was not completely inhibited by the presence of low-density lipoproteins (LDL). HDL sphingomyelin was fundamental for intercellular adhesion molecule-1 (ICAM-1) downregulation in HMEC-1. However, vascular cell adhesion protein-1 (VCAM-1) was not inhibited by rHDL, suggesting that components such as apolipoproteins other than apo AI participate in HDL's regulation of this adhesion molecule. rHDL also induced endothelial nitric oxide synthase eNOS S1177 phosphorylation in HMEC-1 but only when the particle contained sphingomyelin. In conclusion, the internalization of HDL implies the dissociation of lipoprotein components and a SR-BI-independent fast delivery of cholesterol to endothelial cells. HDL internalization had functional implications that were mainly dependent on sphingomyelin. These results suggest a new role of HDL as lipid vectors to the cells, which could be congruent with the antiatherogenic properties of these lipoproteins.

Abstract
One of the primary therapeutic goals of modern cardiology is to design strategies aimed at minimizing myocardial infarct size and optimizing cardiac function following acute myocardial infarction (AMI). Patients with AMI who underwent reperfusion therapy display dysfunction of the coronary endothelium. Consequently, ischemic endothelial cells become more permeable and weaken their natural anti-thrombotic and anti-inflammatory potential. Ischemia-reperfusion injury (IRI) is associated with activation of the humoral and cellular components of the hemostatic and innate immune system, and also with excessive production of reactive oxygen species (ROS), the inhibition of nitric oxide synthase, and with inflammatory processes. Given its essential role in the regulation of vascular homeostasis, involving platelets and leukocytes among others, dysfunctional endothelium can lead to increased risk of coronary vasospasm and thrombosis. Endothelial dysfunction can be prevented by ischemic conditioning with a protective intervention based on limited intermittent periods of ischemia and reperfusion. The molecular mechanisms and signal transduction pathways underlying conditioning phenomena in the coronary endothelium have been described as involving less ROS production, reduced adhesion of neutrophils to endothelial cells and diminished inflammatory reactions. This review summarizes our current understanding of the cellular and molecular mechanisms regulating IRI-affected and -damaged coronary endothelium, and how ischemic conditioning may preserve its function.

Abstract
BACKGROUND Primary cultures endothelial cells have been used as models of endothelial related diseases such atherosclerosis. Biological behavior of primary cultures is donor-dependent and data could not be easily reproducible; endothelial cell lines are emerging options, particularly, human dermal microvascular endothelial cells (HMEC-1), that should be validated to substitute primary cultures for the study of HDL functions. METHODS Morphology, size and granularity of cells were assessed by phase contrast microscopy and flow cytometry of HMEC-1. The adhesion molecules, ICAM-1and VCAM-1 after TNF-α stimulation, and endothelial markers CD105 endoglin, as well as HDL receptor SR-BI were determined by flow cytometry. Internalization of HDL protein was demonstrated by confocal microscopy using HDL labeled with Alexa Fluor 488. HUVECs were used as reference to compared the characteristics with HMEC-1. RESULTS HMEC-1 and HUVEC had similar morphologies, size and granularity. HMEC-1 expressed endothelial markers as HUVECs, as well as functional SR-B1 receptor since the cell line was able to internalize HDL particles. HMEC-1 effectively increased ICAM-1 and VCAM-1 expression after TNF-α stimulation. HUVECs showed more sensibility to TNF-α stimulus but the range of ICAM-1 and VCAM-1 expression was less homogeneous than in HMEC-1, probably due to biological variation of the former. Finally, the expression of adhesion molecules in HMEC-1 was attenuated by co-incubation with HDL. CONCLUSION HMEC-1 possess characteristics of endothelial cells, similar to HUVECs, being a cell line suitable to evaluate the functionality of HDL vis-à-vis the endothelium.

Abstract
The catabolism and structure of high-density lipoproteins (HDL) may be the determining factor of their atheroprotective properties. To better understand the role of the kidney in HDL catabolism, here we characterized HDL subclasses and the catabolic rates of apo A-I in a rabbit model of proteinuria. Proteinuria was induced by intravenous administration of doxorubicin in New Zealand white rabbits (n = 10). HDL size and HDL subclass lipids were assessed by electrophoresis of the isolated lipoproteins. The catabolic rate of HDL-apo A-I was evaluated by exogenous radiolabelling with iodine-131. Doxorubicin induced significant proteinuria after 4 weeks (4.47 ± 0.55 vs. 0.30 ± 0.02 g/L of protein in urine, P < 0.001) associated with increased uremia, creatininemia, and cardiotoxicity. Large HDL2b augmented significantly during proteinuria, whereas small HDL3b and HDL3c decreased compared to basal conditions. HDL2b, HDL2a, and HDL3a subclasses were enriched with triacylglycerols in proteinuric animals as determined by the triacylglycerol-to-phospholipid ratio; the cholesterol content in HDL subclasses remained unchanged. The fractional catabolic rate (FCR) of [(131)I]-apo A-I in the proteinuric rabbits was faster (FCR = 0.036 h(-1)) compared to control rabbits group (FCR = 0.026 h(-1), P < 0.05). Apo E increased and apo A-I decreased in HDL, whereas PON-1 activity increased in proteinuric rabbits. Proteinuria was associated with an increased number of large HDL2b particles and a decreased number of small HDL3b and 3c. Proteinuria was also connected to an alteration in HDL subclass lipids, apolipoprotein content of HDL, high paraoxonase-1 activity, and a rise in the fractional catabolic rate of the [(131)I]-apo A-I.
