ABSTRACT
Although various anticancer drugs have been developed for the treatment of nonsmall cell lung cancer, chemotherapeutic efficacy is still limited. Natural products such as phytochemicals have been screened as novel alternative materials, but alternative funds such as marine bioresources remain largely untapped. Of these resources, marine sponges have undergone the most scrutiny for their biological activities, including antiinflammatory, antiviral, and anticancer properties. However, the biological mechanisms of the activities of these marine sponges are still unclear. We investigated the anticancer activity of marine sponges collected from Kosrae in Micronesia and examined their mechanisms of action using nonsmall cell lung cancer A549 cells as a model system. Of 20 specimens, the Haliclona sp. (KO1304-328) showed both dose- and time-dependent cytotoxicity. Further, methanol extracts of Haliclona sp. significantly inhibited cell proliferation and cell viability. A549 cells treated with Haliclona sp. demonstrated induced expression of c-Jun N-terminal kinase (JNK), p53, p21, caspase-8, and caspase-3. The percentage of apoptotic cells significantly increased in A549 cultures treated with Haliclona sp. These results indicate that Haliclona sp. induces apoptosis via the JNK-p53 pathway and caspase-8, suggesting that this marine sponge is a good resource for the development of drugs for treatment of nonsmall cell lung cancer.

Haliclona sp. extract increased apoptosis. A549 cells were treated with Haliclona sp. extract for 48 h. Apoptotic cells were determined by Annexin V and PI staining and analyzed as described in Section 2. (a) Upper left, necrosis (%); upper right, late apoptosis (%); lower left, viable (%); lower right: early apoptosis (%). (b) The data showed total apoptosis (early apoptosis and late apoptosis).

fig6: Haliclona sp. extract increased apoptosis. A549 cells were treated with Haliclona sp. extract for 48 h. Apoptotic cells were determined by Annexin V and PI staining and analyzed as described in Section 2. (a) Upper left, necrosis (%); upper right, late apoptosis (%); lower left, viable (%); lower right: early apoptosis (%). (b) The data showed total apoptosis (early apoptosis and late apoptosis).

Mentions: To verify the induction of apoptosis, cells treated with Haliclona sp. extract were stained with Annexin V and PI. As shown in Figure 6, the percentage of apoptotic cells increased in a dose-dependent manner, suggesting that Haliclona sp. extracts have apoptosis-inducing activity via the JNK and extrinsic apoptotic pathway.
