Transcriptomic analysis of the role of RasGEF1B circular RNA in the TLR4/LPS pathway

Circular RNAs (circRNAs) have recently emerged as a large class of novel non-coding RNA species. However, the detailed functional significance of the vast majority of them remains to be elucidated. Most functional characterization studies targeting circRNAs have been limited to resting cells, leavin...
