Cell migration plays an important role in tumor cell invasion and metastasis. Previously, we reported that caspase-8 contributes to cell migration and adhesion, a novel nonapoptotic function of an established apoptotic factor. Herein, we report that pro-caspase-8 is capable of restoring cell migration/adhesion to caspase-8-null cells, establishing the first biological function of a pro-caspase....

Cytotoxic activity profiling of the n-hexane extract from fruit pulp Ginkgo biloba L. (Gingkgoaceae) led to purification 8 compounds. HPLC based identified a cytotoxic alkenylresorcinol. The was further separated by time-based fractionation in gradient condition, and cytotoxicity each fraction evaluated using 293, B16F10, BJAB, HCT116 cancer cells vitro. Bilobol isolated as an active constituen...

Caspase-8 is a key apical sensory protein that governs cell responses to environmental cues, alternatively promoting apoptosis, proliferation, and cell migration. The proteins responsible for integration of these pathways, however, have remained elusive. Here, we reveal that Rab5 regulates caspase-8-dependent signaling from integrins. Integrin ligation leads to Rab5 activation, association with...
