The zebrafish represents a fascinating model for studying key aspects of the vertebrate
circadian timing system. Easy access to early embryonic development has made this …

Since the evolution of the aerobic metabolism, reactive oxygen species (ROS) have
represented significant challenges to diverse life forms. In recent decades, increasing …

The zebrafish has proven to be a valuable model organism for studying hematopoiesis, but
relatively little is known about zebrafish immune cell development and functional diversity …

Over recent decades, changes in zebrafish (Danio rerio) behaviour have become popular
quantitative indicators in biomedical studies. The circadian rhythms of behavioural …

Most organisms possess circadian clocks that are able to anticipate the day/night cycle and
are reset or “entrained” by the ambient light. In the zebrafish, many organs and even …

Reactive oxygen species (ROS) play a key role in cell physiology and function. ROS
represents a potential source of damage for many macromolecules including DNA. It is …

Our understanding of the molecular and cellular organization of the circadian timing system
in vertebrates has increased enormously over the past decade. In large part, progress has …

The master circadian clock in fish has been considered to reside in the pineal gland. This
dogma is challenged, however, by the finding that most zebrafish tissues contain molecular …

Light constitutes a primary signal whereby endogenous circadian clocks are synchronized
('entrained') with the day/night cycle. The molecular mechanisms underlying this vital …

Progestins alter hormone homeostasis and may result in reproductive effects in humans and
animals. Thus far, studies in fish have focused on the hypothalamic–pituitary–gonadal …
