Fig 9. mRNA expression of various components of the S1P signalling system in THP-1 macrophages following stimulation with 10% cigarette smoke extract for 24h.

Fig 9

*:Significant increase in mRNA expression of SPHK1, SPHK2,S1PR2, S1PR5, but no significant changes were found in SGPL1 and SGPP2 compared to non-stimulated macrophages (p<0.05).
