Abstract
Apoptosis is the major form of programmed cell death in animals, playing a crucial role in development and tissue homeostasis. Alterations of apoptosis are involved in major pathologies such as cancers and neurodegenerative diseases. The group of proteins known as Bcl-2 family members are at the core of the implementation of this process, to the point that any cancer study almost compulsorily follows the expression of these proteins. For long, the literature about the molecular aspects underlying their function has often been contradictory, if not overly simplified. However, recent breakthroughs have been obtained with structural and imaging methods, offering the opportunity to shed light on many elusive and hardly understandable observations made in the last 20 years, starting when investigators recognized the connection between Bcl-2 family members and mitochondria. This survey does not intend to be an exhaustive review of the large amount of literature on Bcl-2 family members. Rather, we would like to highlight issues that have been somewhat overlooked in the mainstream literature and that might deserve more attention in the light of recent advances. As mitochondriologists have moved toward the field of apoptosis, our views might be different from the ones of many of our colleagues who have done the reverse journey. Our wish is that some of our readers will find them interesting enough to embark upon studying this exciting and fascinating family of proteins.
