HPV-Induced Recurrent Laryngeal Papillomatosis: Fatty Acid Role-Players
並列摘要
Human papilloma virus-induced recurrent laryngeal papillomatosis is considered a troublesome and dangerous disease, because it can cause airway obstruction. Better understanding of metabolic pathways followed under pathological conditions can contribute to improved therapies by which growth and recurrence may be obviated. Part I of this study presents a clinically relevant total lipid fatty acid profile for papilloma cells, analyzed by gas liquid chromatography and a phosholipid red blood cell profile for RLP patients, analyzed by thin layer chromatography. In the papilloma cells virus interference with delta-6 and delta 5- desaturase activities is prevalent and the n–9 FA metabolic pathway is followed. It is plausible that up-regulated fatty acid synthase and Δ9 desaturase activities occur, since enhanced saturated fatty acids and monounsaturated fatty acid levels are also prevalent. High saturated fatty acid levels are known for their propensity to interfere with delta-6 and delta-5 desaturase activities and this is reflected in the blood profile of the RLP patients. It is also known that enhanced saturated fatty acid levels can contribute to enhanced cyclooxygenase-2 activity. Furthermore, cumulative oxidative stress with an oxidative burst is responsible for complete exhaustion of exogenous dietary arachidonic acid intake in these patients. The role of linoleic acid needs to be defined. The dietary intakes of lipids and micronutrients in RLP patients and a rationale for adjuvant FA therapy in the management of these patients are discussed in parts II and III of the study.
