The still largely obscure molecular events in the glioblastoma oncogenesis, a
primary brain tumor characterized by an inevitably dismal prognosis, impel for
investigation. The importance of Long noncoding RNAs as regulators of gene
expression has recently become evident. Among them, H19 has a recognized
oncogenic role in several types of human tumors and was shown to correlate to
some oncogenic aspects of glioblastoma cells. Here we, hypothesyze that in
glioblastoma H19 exerts its function through the interaction with the catalytic
subunit of the PRC2 complex, EZH2. By employing a factor analysis on a SAGE
dataset of 12 glioblastoma samples, we show that H19 expression in glioblastoma
tissues correlates with that of several genes involved in glioblastoma growth and
progression. H19 knock-down reduces viability, migration and invasiveness of two
distinct human glioblastoma cell lines. Most importantly, we provide a
mechanistic perspective about the role of H19 in glioblastoma cells, by showing
that its expression is inversely linked to that of NKD1, a negative regulator of
Wnt pathway, suggesting that H19 might regulate NKD1 transcription via
EZH2-induced H3K27 trimethylation of its promoter. Indeed, we showed that H19
binds EZH2 in glioblastoma cells, and that EZH2 binding to NKD1 and other
promoters is impaired by H19 silencing. In this work we describe H19 as part of
an epigenetic modulation program executed by EZH2, that results in the repression
of Nkd1. We believe that our results can provide a new piece to the complex
puzzle of H19 function in glioblastoma.
