Is argonaute 2 up-regulated in tissues of urothelial carcinoma of bladder?
These results suggest that the aberrant expression of Ago2 in human UCB is possibly involved with tumorigenesis and development, and the Ago2 protein could act as a potential biomarker for prognosis assessment of bladder cancer. Further studies on the cellular functions of Ago2 need to address these issues.
Three main conclusions arise from our results. First, there is a genetic interaction between SEC9 and the V-ATPase, although it is unlikely that this interaction has functional significance with respect to membrane fusion or SNAREs. Second, Sro7p acts to promote SNARE complex formation. Finally, Sec9p function and SNARE complex formation are tightly coupled to the physiological state of the cell.
