Does azithromycin analogue CSY0073 attenuate lung inflammation induced by LPS challenge?
Unlike azithromycin, CSY0073 had no antibacterial effects but it did have a similar anti-inflammatory profile to that of azithromycin. Hence, CSY0073 may have potential as a long-term treatment for patients with chronic lung diseases.
The finding that piRNAs are processed from extended 3' UTRs suggests a role for piRNAs in the remodeling of 3' UTRs. The presence of both clusters and extended 3'UTRs in somatic cells, with evidence for involvement of MIWI2, indicates that this pathway is more broadly distributed than currently appreciated.
