Lordan R, Tsoupras A, Zabetakis I. The Potential Role of Dietary Platelet-Activating Factor Inhibitors in Cancer Prevention and Treatment. Adv Nutr 2019; 10:148-164. [PMID: 30721934 PMCID: PMC6370273 DOI: 10.1093/advances/nmy090] [Citation(s) in RCA: 28] [Impact Index Per Article: 5.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2018] [Revised: 09/11/2018] [Accepted: 10/10/2018] [Indexed: 12/11/2022] Open
Abstract
Cancer is the second leading cause of mortality worldwide. The role of unresolved inflammation in cancer progression and metastasis is well established. Platelet-activating factor (PAF) is a key proinflammatory mediator in the initiation and progression of cancer. Evidence suggests that PAF is integral to suppression of the immune system and promotion of metastasis and tumor growth by altering local angiogenic and cytokine networks. Interactions between PAF and its receptor may have a role in various digestive, skin, and hormone-dependent cancers. Diet plays a critical role in the prevention of cancer and its treatment. Research indicates that the Mediterranean diet may reduce the incidence of several cancers in which dietary PAF inhibitors have a role. Dietary PAF inhibitors such as polar lipids have demonstrated inhibitory effects against the physiological actions of PAF in cancer and other chronic inflammatory conditions in vitro and in vivo. In addition, experimental models of radiotherapy and chemotherapy demonstrate that inhibition of PAF as adjuvant therapy may lead to more favorable outcomes. Although promising, there is limited evidence on the potential benefits of dietary PAF inhibitors on cancer prevention or treatment. Therefore, further extensive research is required to assess the effects of various dietary factors and PAF inhibitors and to elucidate the mechanisms in prevention of cancer progression and metastasis at a molecular level.

Abstract
Adhesions formation is considered a significant clinical entity implicating the healing process following major abdominal surgery, with serious clinical consequences and need for substantial health care expenditures. Several agents and substances applied either locally or systematically could potentially function as inhibitors of the formation of peritoneal adhesions endowed by limiting tissue apposition during the critical stages of mesothelial repair. Phospholipids are identified as surfactant-like substances, acting as a temporary membrane-like coverage of serosal defects. The experimental use of phospholipids for adhesions formation totals 24 publications. All retrieved studies, out of two, demonstrated the efficacy of phospholipids use in adhesions prevention. A single intraperitoneal dose of approximately 75 mg/kg of phosphatidylcholine, for a 30-min exposure time, emerges as the standard practice in terms of efficacy in both surgical alone or combined to peritonitis settings. The findings revealing an unimpeded healing of anastomoses and laparotomy wounds support the safety of this agent. The two additional properties of intraperitoneal use of phospholipids involve the inhibition of bacterial adherence/growth following impregnation of intra-abdominal drainages with phospholipids, without influencing bacterial translocation and the elimination of peritoneal carcinosis, through inhibition of intraperitoneal adhesion of tumor cells. The latter effect is achieved by a dose of phospholipids equal to 150 mg/kg. These experimental data, support that the intraperitoneal phospholipids administration can forestall adhesions formation following intra-abdominal surgical trauma, with no considerable overdosing-related adverse effects. Furthermore, these substances could possibly attenuate posttraumatic inflammation, and inhibit intraperitoneal tumor cell adhesion.

Abstract
During many years, the milk fat has been unfairly undervalued due to its association with higher levels of cardiovascular diseases, dyslipidaemia or obesity, among others. However, currently, this relationship is being re-evaluated because some of the dairy lipid components have been attributed potential health benefits. Due to this, and based on the increasing incidence of cancer in our society, this review work aims to discuss the state of the art concerning scientific evidence of milk lipid components and reported anticancer properties. Results from the in vitro and in vivo experiments suggest that specific fatty acids (FA) (as butyric acid and conjugated linoleic acid (CLA), among others), phospholipids and sphingolipids from milk globule membrane are potential anticarcinogenic agents. However, their mechanism of action remains still unclear due to limited and inconsistent findings in human studies.

Abstract
Glycerophospholipids and sphingolipids participate in a variety of indispensable metabolic, neurological, and intracellular signaling processes. In this didactic paper we review the biological roles of phospholipids and try to unravel the precise nature of their putative healthful activities. We conclude that the biological actions of phospholipids activities potentially be nutraceutically exploited in the adjunct therapy of widely diffused pathologies such as neurodegeneration or the metabolic syndrome. As phospholipids can be recovered from inexpensive sources such as food processing by-products, ad-hoc investigation is warranted.

Abstract
BACKGROUND Intraperitoneal tumor cell attachment after resection of gastrointestinal cancer may lead to a developing of peritoneal carcinosis. Intraabdominal application of phospholipids shows a significant decrease of adhesion formation even in case of rising tumor cell concentration. METHODS In experiment A 2*106 colonic tumor cells (DHD/K12/Trb) were injected intraperitonely in female BD-IX-rats. A total of 30 rats were divided into three groups with treatments of phospholipids at 6% or 9% and the control group. In experiment B a total of 100 rats were divided into ten groups with treatments of phospholipids at 9% and the control group. A rising concentration of tumor cells (10,000, 50,000, 100,000, 250,000 and 500,000) were injected intraperitonely in female BD-IX-rats of the different groups. After 30 days, the extent of peritoneal carcinosis was determined by measuring the tumor volume, the area of attachment and the Peritoneal Cancer Index (PCI). RESULTS In experiment A, we found a significant reduction (control group: tumor volume: 12.0 +/- 4.9 ml; area of tumor adhesion: 2434.4 +/- 766 mm2; PCI 28.5 +/- 10.0) of peritoneal dissemination according to all evaluation methods after treatment with phospholipids 6% (tumor volume: 5.2 +/- 2.2 ml; area of tumor adhesion: 1106.8 +/- 689 mm2; PCI 19.0 +/- 5.0) and phospholipids 9% (tumor volume: 4.0 +/- 3.5 ml; area of tumor adhesion: 362.7 +/- 339 mm2; PCI 13.8 +/- 5.1). In experiment B we found a significant reduction of tumor volume in all different groups of rising tumor cell concentration compared to the control. As detected by the area of attachment we found a significant reduction in the subgroups 1*104, 25*104 and 50*104. The reduction in the other subgroups shows no significance. The PCI could be reduced significantly in all subgroups apart from 5*104. CONCLUSION In this animal study intraperitoneal application of phospholipids resulted in reduction of the extent of peritoneal carcinomatosis after intraperitoneal administration of free tumor cells. This effect was exceptionally noticed when the amount of intraperitoneal tumor cells was limited. Consequently, intraperitoneal administration of phospholipids might be effective in reducing peritoneal carcinomatosis after surgery of gastrointestinal tumors in humans.

Langenbecks Arch Surg 2006; 391:96-101. [PMID: 16534652 DOI: 10.1007/s00423-006-0025-9] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2005] [Accepted: 12/21/2005] [Indexed: 10/24/2022]
Abstract
BACKGROUND AND AIMS Intraperitoneal tumor cell adhesion to extracellular matrix and to mesothelial cells mediated by integrins is an important step in developing peritoneal carcinosis. In former animal studies, we could demonstrate that intraperitoneal treatment with a new phospholipid (PL) emulsion significantly reduces the amount of peritoneal carcinosis by adhesion prevention. This in vitro study tries to elucidate the influence of phospholipids on cells of the human gastric cancer cell line (NUGC-4) and the human rectal cancer cell line (HRT-18) adhering to mesothelial cells (HOMC) in a monolayer culture in vitro. MATERIALS AND METHODS HOMC cells were derived from omentum majus from patients undergoing elective abdominal surgery. Three passages of both cancer cell lines (NUGC-4 and HRT-18) were used. 1x10(5)/100 microl (HRT-18) or 1.2x10(5)/100 microl (NUGC-4) cells, according to forgoing dilution series, were pretreated with different concentrations of phospholipid emulsion (0.05, 0.1, 0.5, 0.75, 1% PL) stained with cell tracker chloromethyl-benzamidodialkylcarbocyanine (CM-DIL) and seeded into each well on the mesothelial monolayer. After 90 min, the number of adherent cells was counted by fluorescence microscopy at 530 and 620 nm. Additionally, flow cytometric analysis of integrin alpha3 and beta1 expression on the tumor cell surface after treatment with phospholipids was completed. RESULTS We found a dose dependent effect of phospholipids on both tumor cell lines causing a reduction of cell-cell adhesion. Already low concentrations of phospholipids (PL 0.5) had a significant influence. The mean cell count could be reduced from 234+/-12/mm2 in controls to 124+/-41/mm2 (PL 0.5; NUG-4) and from 295+/-49/mm2 to 169+/-29/mm2 (PL 0.5; HRT-18), respectively. Additionally, the integrin alpha3 and beta1 expression on both cell lines could be reduced. CONCLUSION Our results within the scope of published data indicate that adhesion prevention is capable to reduce peritoneal carcinosis.
