Epithelial stromal cells represent a major cellular component of human uterine endometrium that is subject to tight hormonal regulation. Through cell-cell contacts and/or paracrine mechanisms, stromal cells play a significant role in the malignant transformation of epithelial cells. We isolated stromal cells from normal human endometrium and investigated the morphological and transcriptional ch...

The Goodwin oscillator is a simple yet instructive mathematical model, describing a wide range of self-controlled biological and biochemical processes, among which are selfinhibitory metabolic pathways and genetic circadian clocks that lead to important applications, such as the hormonal cycles modeling. Indeed, one of the first models of hormonal rhythm, squarely based on the conventional Good...

The thyroid, the largest gland in the endocrine system, secretes hormones that help promote bodily growth and development. This gland regulates hormonal secretion rate in spite of changes in dietary iodine which is a key ingredient in the hormone's biosynthesis. The thyroid relies on several feedback mechanisms for this regulation, and in this paper we use recent molecular-level and clinical ob...

Activities of drug-metabolizing enzymes (DMEs) are known to change throughout the course of physical and sexual maturation, with the greatest variability noted during infancy and adolescence. The mechanisms responsible for developmental regulation of DME are currently unknown. However, the hormonal changes associated with puberty/adolescence provide a theoretical framework for understanding the...

conclusions the hormonal levels were low in patients with idiopathic dilated cardiomyopathy. however, the prognostic significance of different hormonal deficiencies was not clear in our study populations who were receiving standard therapies for heart failure and had a relatively stable clinical condition. results except for testosterone level, the levels of gh, igf-1, t3, and t4 concentrations...

Hormones play key roles in the regulation of animal and plant life histories, particularly in the timing of transitions between prematurational stages and in the scheduling of reproduction. Furthermore, hormonal mechanisms are subject to information about the external and internal environment of the individual. Within an evolutionary radiation, the same hormone subsets often regulate the schedu...

It is well known that nutrient availability controls plant development. Moreover, plant development is finely tuned by a myriad of hormonal signals. Thus, it is not surprising to see increasing evidence of coordination between nutritional and hormonal signaling. In this opinion article, we discuss how nitrogen signals control the hormonal status of plants and how hormonal signals interplay with...
