To overcome the hostile hypoxic microenvironment of solid tumors, tumor cells secrete a large number non-coding RNA-containing exosomes that facilitate development and metastasis. However, precise mechanisms cell-derived during hypoxia are unknown. Here, we aim to clarify whether affects growth progression by transferring long RNA-urothelial cancer-associated 1 (lncRNA-UCA1) enriched secreted from bladder cancer cells. We used 5637 with high expression lncRNA-UCA1 as exosome-generating UMUC2...

Macrophages, characterized by considerable diversity and plasticity, play a crucial role in broad spectrum of biological processes, including inflammation. However, the molecular mechanisms underlying diverse phenotypes macrophages are not well defined. Here, we show that RNA-binding protein, quaking (QKI), dynamically modulates macrophage polarization states. After lipopolysaccharide (LPS) stimulation, QKI-silenced RAW 264.7 cells displayed pro-inflammatory M1 phenotype increased expression...

It has been revealed that 2'3'-cyclic-GMP-AMP (cGAMP), a second messenger activates the antiviral stimulator of IFN genes (STING), elicits an antitumoral immune response. Since cGAMP cannot cross cell membrane, it is not clear how intracellular STING activated by extracellular until SLC19A1 was identified as importer to transport into cytosol. However, SLC19A1-deficient cells also sense cGAMP, suggesting presence mechanisms other than facilitating transporters for sensing cGAMP. Here, using...
