Current Opinion in Plant Biology, 2002
Seed dormancy and germination are complex adaptive traits of higher plants that are influenced by a large number of genes and environmental factors. Studies of genetics and physiology have shown the important roles of the plant hormones abscisic acid and gibberellin in the regulation of dormancy and germination.

Dormancy or torpor is a widely-recognized behavioral and physiological state of bothanimals and plants that generally indicates inactivity and reduced metabolic rate. It caninvolve very different physiological states in response to a variety of environmentalstimuli, including temperature, water, or food.

Cold Spring Harbor Perspectives in Medicine, 2023
The pattern of delayed recurrence in a subset of breast cancer patients has long been explained by a model that incorporates a variable period of cellular or tumor mass dormancy prior to disease relapse. In this review, we critically evaluate existing data to develop a framework for inferring the existence of dormancy in clinical contexts of breast ...

Dormancy in the Tumor Microenvironment
2021Tumor cells frequently disseminate to distant organ sites, where they encounter permissive or restrictive environments that enable them to grow and colonize or enter a dormant state. Tumor dormancy is not strictly defined, but generally describes a tumor cell that is non-proliferative or in a state of balanced equilibrium, in which the proliferation ...

Plants growing in temperate and boreal regions of the world have to face strikingly different environmental conditions during summer and winter. Being sessile organisms, plants have had to develop various strategies to adapt to these changes in light, temperature, and water availability, thereby optimizing their 'economy of growth'. While annual plants

Dormancy and Dormancy Release in White Spruce
Forest Science, 1966Abstract Picea glauca (Moench) Voss shows typical dormancy of winter buds. To break dormancy the trees should be chilled 4 to 8 weeks at 36° to 40°F., depending on their developmental stage and age when the treatment is begun.

Journal of Surgical Oncology, 1990
AbstractA case is presented in which multiple nodules of recurrent cancer appeared about the scar 25 years after radical mastectomy. They were accompanied by an inflammatory reaction. Breast cancers may recur as long as 50 years after surgery. Such late recurrence is accomplished by the cancer cell entering a “dormant” state in which little or no de ...

Annual Review of Entomology, 1986
Diapause is frequently viewed as a developmental strategy unique to insects of the temperate zone. My primary objective in this review is to dispell this myth by presenting evidence for the widespread existence of diapause among tropical species. Although the environmental regulators are still poorly defined, I attempt to identify factors implicated in

This chapter summarizes clinical evidence on tumor dormancy, with a special focus on our research supporting the role of dormancy both in local and distant recurrence of breast cancer following mastectomy. Starting from these premises, we propose a model of neoplastic development that allows us to elucidate several relevant clinical phenomena ...
