The circadian clock is an endogenous time keeping system shared by most
organisms. In mammals, a master pacemaker in the hypothalamus orchestrates
temporal alignment of behavior and physiology by transmitting daily signals to
multiple clocks in peripheral tissues. Disruption of this communication has a
profound affect on human health and has been linked to diverse pathogenic
conditions, including cancer. At the center of the molecular circadian machinery
is a set of clock genes, generating rhythmic oscillations on a cellular level. In
the past several years, research from different fields has revealed the
complexity and ubiquitous nature of circadian regulation, uncovering intriguing
associations between clock components and cellular pathways implicated in
tumorigenesis. In this review, we discuss the emerging role of circadian genes in
hematological and hormone-related malignancies. These new insights suggest that
manipulating circadian biology as a way to fight cancer, as well as, other life
threatening diseases is within the realm of possibility.
