The long non-coding RNA LUCAT1 is a negative feedback regulator of the Interferon Response in humans (LPS dataset)

Project description:Long non-coding RNAs (lncRNAs) are important regulators of biological processes including immune responses. In the immune system, the immunoregulatory functions of lncRNAs have been revealed in murine studies with limited understanding of lncRNAs and the immune response in humans. Here, we identified lncRNA LUCAT1 as amongst the most dynamically regulated non-coding transcripts in human myeloid cells stimulated with lipopolysaccharide (LPS) and other activators of the innate immune response.

The long non-coding RNA LUCAT1 is a negative feedback regulator of interferon responses in humans.

Project description:Long non-coding RNAs are important regulators of biological processes including immune responses. The immunoregulatory functions of lncRNAs have been revealed primarily in murine models with limited understanding of lncRNAs in human immune responses. Here, we identify lncRNA LUCAT1 which is upregulated in human myeloid cells stimulated with lipopolysaccharide and other innate immune stimuli. Targeted deletion of LUCAT1 in myeloid cells increases expression of type I interferon stimulated genes in response to LPS. By contrast, increased LUCAT1 expression results in a reduction of the inducible ISG response. In activated cells, LUCAT1 is enriched in the nucleus where it associates with chromatin. Further, LUCAT1 limits transcription of interferon stimulated genes by interacting with STAT1 in the nucleus. Together, our study highlights the role of the lncRNA LUCAT1 as a post-induction feedback regulator which functions to restrain the immune response in human cells.

LncRNA LUCAT1 Promotes Glioblastoma Progression by Enhancing HIF1⍺ Activity [ChIP-seq]

Project description:Glioblastoma (GBM) is characterized by a high degree of hypoxia. Hypoxia-inducible factors (HIFs) modulate glioma stem-like cell (GSC) responses to hypoxia and promote GBM progression, therapeutic resistance, and recurrence. Here we identify a new transcript of the long non-coding RNA LUCAT1 and show that it reinforces HIF1⍺ signaling in GSCs under hypoxia. LUCAT1 expression is highly induced under hypoxia in GBM and GSCs in a HIF1⍺-dependent manner. High LUCAT1 expression in human GBM correlates with increased aggression and poor survival. Mechanistically, LUCAT1 associates with chromatin and modulates interaction between HIF1⍺ and coactivator CBP to hypoxia response elements (HREs) to drive HIF1⍺-target gene expression under hypoxia. Thus, LUCAT1 acts as a positive feedback factor to augment HIF1⍺ signaling under hypoxic stress in GSCs. Loss of LUCAT1 reduces tumor growth and prolongs mouse survival in xenograft models of GBM. Our findings provide new insights into how GSCs regulate gene expression under hypoxia and identify LUCAT1 as therapeutic target in GBM.
