Latrunculin B originates from Latrunculia (now Negombata) magnifica, a sponge from the Red Sea. Latrunculin B inhibits the assembly of actin microfilaments by 1:1 molecular binding of free actin monomers in the cell cytoplasm. It may be a potential therapeutic agent for glaucoma. Latrunculin B induced destabilization of the actin microfilament and apoptosis in a dose-dependent manner, as demonstrated by morphological changes and nuclear condensation in the PC3M cells. In addition, it resulted in an increase in the levels of gamma-H2AX recruitment, implicating the induction of DNA damage, including double-strand breaks. Induction of Bax, with little effect on Bcl-2 expression, indicated that actin disruption causes apoptosis through activation of Bax signaling in PC3M cells. This data might helps to develop the strategy for actin-based anticancer chemotherapy against highly metastatic prostate cancer.
