Cyclic adenosine monophosphate (cAMP) is a second messenger responsive to many external stimuli, playing an important role in cellular gene expression, metabolism, migration, differentiation, hypertrophy, apoptosis and secretion. All of these cellular functions are important in many diseases including cancer. Most of its effects were initially attributed to the classical protein kinase A (PKA) protein, but cellular functions such as proliferation and migration were found to be PKA independent and dependent on the newly discovered exchange proteins directly activated by cAMP (EPACs). EPACs are single polypeptides that primarily function as guanine exchange factors (GEFs) for Rap proteins that allow the …

Combination chemotherapy is commonly used to treat cancer, because such a therapy regimens usually involve sequential administration of multiple drugs and allow targeting different cell signaling pathway. The co-delivery of drug combination at a controlled ratio via the same vehicle is offering the advantages such as spatial-temporal synchronization of drug exposure, synergistic therapeutic effects and suppression of drug resistance. Undoubtedly, there are several molecular and pharmacological factors that determine the effectiveness of drug combinations. A rationally designed drug combination is required since certain drug ratios and the definitive exposure to the targets of interest can only be synergistic while others …
