In Vitro	Tetraethylammonium (0.2-60 mM; 24-72 hours; C6 and 9L glioma cells) treatment inhibits the proliferation of C6 and 9L cells in a dose- and time-dependent manner[1]. Tetraethylammonium (40 mM; 24-72 hours; C6 and 9L glioma cells) treatment significantly increases apoptosis in cells[1]. Tetraethylammonium (40 mM; 12-48 hours; C6 and 9L glioma cells) treatment significantly elevates Bax/Bcl-2 protein ratio in a time-dependent manner[1]. The generation of intracellular ROS increased in C6 and 9L cells by the addition of 20 and 40 mM Tetraethylammonium[1]. Cell Proliferation Assay[1] Cell Line: Rat C6 and 9L glioma cells Concentration: 0.2 mM, 2 mM, 20 mM, 40 mM and 60 mM Incubation Time: 24 hours, 48 hours and 72 hours Result: Inhibited the proliferation of C6 and 9L cells in a dose- and time-dependent manner. Apoptosis Analysis[1] Cell Line: Rat C6 and 9L glioma cells Concentration: 40 mM Incubation Time: 24 hours, 48 hours and 72 hours Result: Significantly increased apoptosis in cells. Western Blot Analysis[1] Cell Line: Rat C6 and 9L glioma cells Concentration: 40 mM Incubation Time: 12 hours, 24 hours, 48 hours Result: The expression of Bax was markedly increased, while that of Bcl-2 showed a decreasing trend 12, 24 and 48 h.
In Vivo	Tetraethylammonium (1 mM, 3 mM, and 5 mM) significantly increases the amplitude and frequency of contractility of colon and rectum from rats in longitudinal and circular direction. Tetraethylammonium at 5 mM and 15 mM concentrations shows no effect on histology of colon and rectum from rats that are administered locally with Tetraethylammonium into colon lumen from anus for 10 days[2].
