Is expression of TIP30 tumor suppressor gene down-regulated in human colorectal carcinoma?
Our results demonstrate that promoter methylation is involved in the decreased expression of TIP30 tumor suppressor gene in human colorectal carcinoma.
At the nicotinic acetylcholine receptor, isoflurane and sevoflurane act primarily through the same mechanisms: Both affect the open and the closed state of the channels in concentrations equal to and less than those encountered clinically. The kinetics of desensitization, however, are altered in a different manner. Thus there may be several different sites of interaction.
