lncRNA regulates expression and function of innate immune transcription factor IRF1 in macrophages.

The discovery of long non-coding RNAs (lncRNAs) has provided a new perspective on the centrality of RNA in gene regulation and genome organization. Here, we screened for lncRNAs with putative functions in the host response to single-stranded RNA respiratory viruses. We identify as a conserved cis-acting lncRNA up-regulated in three respiratory diseases to control the expression of its antisense gene , a key transcriptional regulator of the antiviral response.

Irradiation abolishes smooth muscle investment into vascular lesions in specific vascular beds.

The long-term adverse effects of radiotherapy on cardiovascular disease are well documented. However, the underlying mechanisms responsible for this increased risk are poorly understood. Previous studies using rigorous smooth muscle cell (SMC) lineage tracing have shown abundant SMC investment into atherosclerotic lesions, where SMCs contribute to the formation of a protective fibrous cap.
