Regulation of Metabolism01:19

Regulation of Metabolism

12.5K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Plant Hormones01:56

Plant Hormones

28.6K
Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

6.6K
Hormones intricately bind to receptors on the surface or within target cells, initiating a cascade of cellular responses.
Notably, the cellular response can be regulated by altering the number of receptors expressed in the cell. For example, prolonged exposure to elevated hormone levels results in a gradual decline or down-regulation in the number of receptors for that specific hormone on the cell surface. Conversely, in response to low hormone levels, cells may use up-regulation, producing an...

Hormonal Regulation01:33

Hormonal Regulation

37.3K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Signal Transduction: Overview01:26

Signal Transduction: Overview

13.0K
Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...

Area of Science:

  • Biological Sciences
  • Biomedical Sciences
  • Toxicology
  • Pharmacology

Background:

  • Hormesis is a key concept explaining beneficial effects at low doses.
  • Understanding dose-response relationships is crucial in medicine and environmental safety.
  • Previous research has documented hormetic effects across various scientific fields.

Purpose of the Study:

  • To provide a comprehensive historical overview of hormesis.
  • To analyze the occurrence and characteristics of hormetic dose responses.
  • To explore the application of hormesis in risk assessment for carcinogens and non-carcinogens.

Main Methods:

  • Literature review of historical dose-response models (threshold, linear, hormetic).
  • Analysis of pharmacological and toxicological studies for hormetic effects.
  • Examination of quantitative, temporal, and mechanistic aspects of hormesis.

Main Results:

  • Hormesis is a frequently observed phenomenon in biological and toxicological literature.
  • The paper details the quantitative and temporal features of hormetic responses.
  • Underlying mechanistic bases for hormesis are discussed.

Conclusions:

  • Hormesis presents a significant departure from traditional linear or threshold models.
  • The concept of hormesis has broad applicability in environmental and clinical risk assessment.
  • Further integration of hormesis into risk assessment frameworks is warranted.
