Hormones are chemical signaling molecules that regulate patterns of cellular physiology and gene expression underlying phenotypic traits. Hormone-signaling pathways respond to an organism's external environment to mediate developmental stage-specific malleability in phenotypes, so that environmental variation ...
Plant hormones, also known as phytohormones, are chemicals that regulate plant cell processes. They are signal molecules produced within the plant functioning in extremely low concentrations. Related Subjects Auxin Brassinosteroid Cytokinin Gibberellins ...
The plant hormones are a structurally unrelated collection of small molecules derived from various essential metabolic pathways. These compounds are important regulators of plant growth and mediate responses to both biotic and abiotic stresses. During the last ten years there have been many exciting adva...

In simple terms, all hormones are basically chemical messengers with various life-spans, which get released from one tissue or another, are transported via the bloodstream or intracellular fluid, and end up at target cells in the same region or different tissues entirely. In our bodies, the var...
An ATP-dependent “pump” that exchanges cytosolic hydrogen ions for luminal potassium ions (H+/K+ATPase) is the essential component of gastric acid secretion. In the inactive resting state, H+/K+ATPase pump molecules are sequestered in membranes of cytosolic tubulovesicles that lie beneath the...
摘要: Contrary to the traditional view, the main olfactory pathway can mediate responses to pheromones as well as to common odours. Recent studies show that pheromone-activated hormonal systems extend widely within the brain.关键词: bioactive glass scaffold tissue engineering X-ray microtomography ...
the underlying stromal cells are known to regulate growth and function of polarized ECs,44 and uterine stromal cells mediate TNF-a release from uterine ECs in the presence of E2.104 It has also been reported that TLRs 1–10 expression levels in murine vaginal ECs were significantly increased dur...
chemical introduction of artificial glycans on peptide hormones64,65,66,67, and interestingly all studies find—very much in line with what we show here for the naturally occurring O-glycans—that the analogs chemically modified with artificial glycan structures are less or equally potent in in ...
