Overview

CTB is a potent p300 histone acetyltransferase activator CTB can effectively induce apoptosis in MCF-7 cells .

In Vitro

CTB (10, 50, 100, 150, 200, and 250 μM; 10 min) enhances p300 HAT activity of p300 in a dosedependent manner. ?\nCTB (0-200 μM; 24 hours) inhibits the viability of MCF-7 cells with an IC 50 of 85.43 μM. ?\nCTB (85.43 μM; 24, 48 and 72 h) induces time dependence apoptosis of MCF-7 cells. ?\nCTB (50 uM; 24?h) increases p300/CBP activity , and reduces autophagic flux in primary neurons. MCE has not independently confirmed the accuracy of these methods. They are for reference only. Cell Viability AssayCell Line: MCF-7 cell Concentration: 0-200 μM Incubation Time: 24 hours Result: Inhibit viability with an IC 50 of 85.43 μM. Apoptosis AnalysisCell Line: MCF-7 cell Concentration: 85.43 μM Incubation Time: 24, 48 and 72 h Result: Iinduced time-dependence apoptosis.
