GAS5 and glioblastoma: The lncRNA, growth arrest-specific transcript 5 (GAS5), has been implicated in dysregulation of the cell cycle and apoptosis in prostate cancer (Romanuik et al. 2010), breast cancer (Zhang et al. 2013b), and non-small cell lung cancer (Shi et al. 2015), and differential GAS5 expression was associated with poor clinical outcome and reduced survival for patients with glioblastoma multiforme (Zhang et al. 2013a), colorectal cancer (Yin et al. 2014), and cervical cancer (Cao et al. 2014).
