For example, Gas5 (growth arrest specific 5), a tumor-suppressive long noncoding RNA, and a small nucleolar RNA (snoRNA) host gene similar to UHG (U22 host gene), encoded 10 human box C/D snoRNAs, can potently upregulates the transcription of tumor necrosis factor (TNF)-related apoptosis inducing ligand (TRAIL) by inducing H3K4 methylation/H3K27 demethylation. The gene discussed is GAS5; the disease is neoplasm.
