Investigating the Effects of Taxol on MCF-7 Cell Cycle Progression and PARP Cleavage

DESCRIPTION

This study examines how Taxol (3 ng/ml) influences cell cycle phases and apoptosis in MCF-7 breast cancer cells using cleaved PARP as a marker. By analyzing the impact of siRNA targeting cyclin B1 and control siGFP in a 40-cell well format, we explore the transition of cells through G2/M and G0/G1 phases. The findings contribute to understanding the molecular mechanisms by which Taxol induces cell death and cell cycle arrest, highlighting the roles of cyclin B1 and PARP in cancer treatments.
