abstract = {Neuroblastoma is the most common extracranial solid tumor
in childhood and arises from neural crest cells of the
developing sympathetic nervous system. Prostaglandin E2
(PGE2) has been identified as a key pro-inflammatory
mediator of the tumor microenvironment (TME) that promotes
neuroblastoma progression. We report that the interaction
between the microRNA miR-574-5p and CUG-binding protein 1
(CUGBP1) induces the expression of microsomal prostaglandin
E2 synthase 1 (mPGES-1) in neuroblastoma cells, which
contributes to PGE2 biosynthesis. PGE2 in turn specifically
induces the sorting of miR-574-5p into small extracellular
vesicles (sEV) in neuroblastoma cell lines. sEV are one of
the major players in intercellular communication in the TME.
We found that sEV-derived miR-574-5p has a paracrine
function in neuroblastoma. It acts as a direct Toll-like
receptor 7/8 (TLR7/8) ligand and induces α-smooth muscle
actin (α-SMA) expression in fibroblasts, contributing to
fibroblast differentiation. This is particularly noteworthy
as it has an opposite function to that in the TME of lung
carcinoma, another PGE2 dependent tumor type. Here,
sEV-derived miR-574-5p has an autokrine function that
inhibits PGE2 biosynthesis in lung cancer cells. We report
that the tetraspanin composition on the surface of sEV is
associated with the function of sEV-derived miR-574-5p. This
suggests that the vesicles do not only transport miRs, but
also appear to influence their mode of action.},
