Proteoglycans: key partners in bone cell biology

Article Abstract:

The complex proteoglycan (PG) composition in bone is addressed together with the specific role played by PGs in bone biology, as regulatory molecules for bone resorption and their involvement in bone tumor development. The roles of anl PG (HSPG) families as bone pro-resorptive agents and promoters of asteolytic tumor have made them good targets for new therapeutic approaches to these osteolytic bone tumors.

Biochemistry and molecular biology of Arabidopsis-aphid interactions

Article Abstract:

The potential of Arabidopsis as a model system to study metabolic and transcriptional responses by infestation of aphid herbivores is discussed. This shows the interactions between plants, aphids and the viruses that they transmit.
