Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="jcp24446-sec-0001" sec-type="section"> <p>MicroRNAs (miRNAs) are small noncoding RNA molecules that regulate protein expression by cleaving or repressing the translation of target mRNAs. In mammals, their function mainly represses the mRNA transcripts via imperfect complementary sequences in the 3′UTR of target mRNAs. Several miRNAs have been recently reported to be involved in modulation of different genes in tumors, including glioblastoma, the most frequent brain tumor in adults. Despite the improvements in treatments, survival of patients remains poor, and glioblastoma is one of the most lethal form of human cancer. To define novel strategies against this tumor, emerging research investigated miRNAs involvement in glioblastoma. In particular, this review is focused on miRNAs involved on the two principal programmed cell‐death, apoptosis and autophagy, recently described from the literature. Moreover, the discovery of miRNAs role in glioma cell‐death pathways has also revealed a new category of therapeutic targets, fundamental for this kind of tumor. J. Cell.
