Mechanisms of tamoxifen-induced apoptosis

Apoptosis : an International Journal on Programmed Cell Death
S Mandlekar, A N Kong

Abstract

Tamoxifen (TAM) has been used in the treatment of breast cancer for over a decade. The observed clinical efficacy of TAM has been attributed to both growth arrest and induction of apoptosis within the breast cancer cells. Although the primary mechanism of action of TAM is believed to be through the inhibition of estrogen receptor (ER), research over the years has indicated that additional, non-ER-mediated mechanisms exist. These include modulation of signaling proteins such as protein kinase C (PKC), calmodulin, transforming growth factor-beta (TGFbeta), and the protooncogene c-myc. Recent studies, including those from our laboratory, have implicated the role of caspases and mitogen-activated protein kinases (MAPK), including c-Jun N-terminal kinase (JNK) and p38 in TAM-induced apoptotic signaling. Oxidative stress, mitochondrial permeability transition (MPT), ceramide generation as well as changes in cell membrane fluidity may also play important roles in TAM-induced apoptosis. These various signaling pathways underlying TAM-induced apoptosis will be reviewed in this article.

Calcium & Bioenergetics

Bioenergetic processes, including cellular respiration and photosynthesis, concern the transformation of energy by cells. Here is the latest research on the role of calcium in bioenergetics.

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
