Focal adhesion kinase (FAK), a broadly expressed non-receptor tyrosine kinase which transduces signals from integrins, growth and hormonal factors, is a key player in many fundamental biological processes and functions, including cell adhesion, migration, proliferation and survival. The involvement of FAK in this range of functions supports its role in important aspects of organismal development and disease, such as central nervous system and cardiovascular development, cancer, cardiac hypertrophy and tissue fibrosis. Many functions of FAK are correlated with its tyrosine kinase activity, which is temporally and spatially controlled by complex intra-molecular autoinhibitory conformation and inter-molecular interactions with protein and lipid partners. The inactivation of FAK in mice results in embryonic lethality attributed to the lack of proper development and function of the heart. Accordingly, embryonic FAK myocyte-specific knockout mice display lethal cardiac defects such as thin ventricle wall and ventricular septum defects. Emerging data also support a role for FAK in the reactive hypertrophy and failure of adult hearts. Moreover, the mechanisms that regulate FAK in differentiated cardiac myocytes to biomechanical stress and soluble factors are beginning to be revealed and are discussed here together with data that connect FAK to its downstream effectors.

The progress in the development and understanding of interfacial materials for organic photovoltaics (OPV) is reviewed. The proper choice of interface materials is a must for highly efficient and stable OPV devices and has become a significant part of the OPV research today. Interface materials are either non-conducting, semiconducting or conducting layers which not only provide selective contacts for carriers of one sort, but can also determine the polarity of OPV devices, affect the open-circuit voltage, and act as optical spacers or protective layers. In this review both inorganic and organic interface materials are discussed with respect to their function in the OPV device. © 2010 The Royal Society of Chemistry.
