“…Conversely, ceramide content can be reduced by its conversion into SM or complex glycosphingolipids (GSL), a common mechanism from cancer cells to block ceramide-induced cell death signaling [26]. Otherwise, ceramide can be directly phosphorylated into ceramide-1-phosphate (C1P), which mediates in many inflammatory processes through a specific membrane receptor [27][28][29].…”

“…The cells were exposed to 400-500 nm light for 1 h using a transilluminator (white bars) or incubated in the dark (black bars), and then were incubated for 4 h, which is the optimal time for induction of cell migration by C1P in these cells. Results are expressed relative to control (Ctrl) values, with or without light, respectively, and are the mean AE SEM of three independent experiments (*p < 0.05, **p < 0.01) (Taken from Ouro et al, 2014; with permission). ethanol concentration was <0.16%.…”

“…In particular, N-palmitoylceramide 1-phosphate (C16-C1P), or a natural mixture of bovine brain-derived C1P with N-linked fatty acid chains composed mainly of stearic and nervonic acids, were as potent as C8-C1P at stimulating macrophage growth (Gangoiti et al, 2011;Gangoiti et al, 2010a;Gangoiti et al, 2008b). In addition to demonstrating that C1P is mitogenic, we showed that both synthetic short chain C1Ps and natural long-chain C1P were able to inhibit apoptosis (Gangoiti et al, 2008a;Gomez-Munoz et al, 2005Granado et al, 2009a), and to stimulate cell migration in different cell types Granado et al, 2009b;Ouro et al, 2014). In this connection, it should be emphasized that C1P has dual actions on cells, being able to act intra-or extra-cellularly to exert its biological effects.…”

“…Embora condições inadequadas de conservação e extração possam promover a liberação da espécie por hidrólise enzimática, a intensidade relativa reduzida observada em pacientes com CHC nesta pesquisa pode estar correlacionado a supressão de respostas antitumorais. A espécie foi associada a regulação da migração de macrófagos pela inibição da via ceramida-1-fosfato, revelando importante papel no controle de funções patofisiológicas como inflamação e metástase tumoral (OURO et al, 2014). Além disso, é capaz de inibir a ativação da PI 3-quinase, implicada no estímulo da divisão celular e na inibição à apoptose em diversos tipos celulares (LAUENER et al, 1995).…”
