[New generation of androgen receptor antagonist in castration resistant prostate cancer]. 2014

Hiroji Uemura

Androgen ablation therapy is performed for prostate cancer patients especially with advanced stage. Nevertheless, outgrowth of hormone independent cancer cells occurs within several years and leads to a lethal condition, so-called castration resistant prostate cancer (CRPC). Even in CRPC cells under low levels of serum androgens, androgen receptor (AR) signaling still functions and is engaged in the establishment of CRPC. Recently, novel AR antagonists have been developed such as enzalutamide or ARN-509. This review focuses on these AR antagonists that have some features including high affinity to AR compared with bicalutamide, preventing nuclear translocation and DNA binding. These new hormonal agents have changed the landscape of CRPC treatment with a promising outcome.

D004247	DNA	A deoxyribonucleotide polymer that is the primary genetic material of all cells. Eukaryotic and prokaryotic organisms normally contain DNA in a double-stranded state, yet several important biological processes transiently involve single-stranded regions. DNA, which consists of a polysugar-phosphate backbone possessing projections of purines (adenine and guanine) and pyrimidines (thymine and cytosine), forms a double helix that is held together by hydrogen bonds between these purines and pyrimidines (adenine to thymine and guanine to cytosine).

D015398	Signal Transduction	The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
