Plant Hormones01:56

Plant Hormones

24.4K
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.

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

601
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Cancer Prevention

6.3K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Effects of Chemicals: Overview

1.3K
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

Menopause01:28

Menopause

226
Menopause, a natural biological process marking the end of a woman's fertility, typically occurs between the fifth and sixth decade of life. This phase is characterized by the exhaustion of the ovarian follicle pool, leading to less responsive ovaries despite the high levels of Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH). The consequential decrease in estrogen production results in symptoms like hot flashes, heavy sweating, headaches, hair loss, muscle pains, vaginal...

Target Cell Response to Hormones01:22

Target Cell Response to Hormones

3.2K
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...

Area of Science:

  • Phytochemistry
  • Endocrinology
  • Toxicology

Background:

  • Phytoestrogens are plant-derived compounds with estrogenic activity, crucial in plant-predator interactions.
  • Their discovery is linked to observed estrogenic effects in grazing animals and humans.
  • These compounds are found in various chemical families, including isoflavones and flavanones.

Purpose of the Study:

  • To examine phytoestrogen compounds discovered at nutritional concentrations in animals and humans.
  • To discuss their role in plants, metabolic transformations, and bioavailability.
  • To review their health effects, considering factors like sex, age, and physiological status.

Main Methods:

  • Analysis of various phytoestrogen chemical families (flavanones, coumestans, resorcylic acid lactones, isoflavones, enterolignans).
  • Discussion of metabolic transformations and bioavailability.
  • Review of toxicological data and health effects in humans and animal models, referencing doses and exposure.

Main Results:

  • Phytoestrogens exhibit diverse health effects, potentially beneficial or adverse.
  • Effects are contingent upon individual characteristics (sex, age, physiological status) and exposure.
  • Toxicological information is based on official data, with human data prioritized and animal models used supplementally.

Conclusions:

  • Phytoestrogens are significant in plant-predator interactions, with notable effects in humans and animals.
  • Understanding phytoestrogen metabolism, bioavailability, and dose-dependent effects is crucial.
  • Individual variability significantly influences the health outcomes of phytoestrogen consumption.
