However, low expression levels of miR-329 correlate with survival in glioblastoma multiforme patients [47], studies of hippocampal neurons suggest it to be involved in dendritic outgrowth [48], and miR-329 expression is decreased in airway smooth muscle treated with IL-1β, TNFα, and IFNγ [49]. This evidence concerns the gene IL1B and glioblastoma.
