Mechanism of Action

Information	Trichostatin A (TSA) is a broad-spectrum HDAC inhibitor. It affects PI3K/AKT and ERK signaling pathways by inhibiting histone deacetylase activity and increasing histone acetylation, effectively inhibiting tumor cell proliferation and migration, and promoting apoptosis.
