Renieramycin M (RM) is a KCN-stabilized tetrahydroisoquinoline purified from the blue sponge Xestospongia sp., with nanomolar IC50s against several cancer cell lines. Our goal is to evaluate its combination effects with doxorubicin (DOX) in estrogen receptor positive MCF-7 breast cancer cells.

Comparative genomics of cellulolytic shipworm symbionts
Shipworms are marine bivalves that live and feed on wood. These bivalves, like most xylophagous and herbivorous animals, rely on bacterial symbionts to digest the recalcitrant lignocellulose component of plants. What’s unusual about shipworms is that bacterial symbionts are housed intracellularly in the specialized cells in the gills, therefore are not in direct contact with the ingested food particles.
