Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.7K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Understanding Sleep

1.9K
Sleep, an essential biological state, involves significant reductions in physical activity, sensory awareness, and interaction with the environment. This complex physiological process is primarily regulated by specific brain regions, notably the hypothalamus and pons, which govern the sleep-wake cycle or circadian rhythm.
The circadian rhythm, a nearly 24-hour cycle, is deeply influenced by environmental light cues. Light exposure directly affects the hypothalamus, which in turn regulates...

Chronopharmacokinetics: Circadian Rhythms and Influence on Drug Response

484
Circadian rhythms are cyclic changes that are crucial in plasma drug concentrations. Various standard circadian parameters, including core body temperature, heart rate, and other cardiovascular factors, directly impact disease states and the therapeutic response to drug therapy.
The time of drug administration is an important factor to consider, as it can influence the toxic dose of a drug. For example, a study conducted by Prins et al. in 1997 examined the effects of the timing of...

The Pineal Gland01:02

The Pineal Gland

8.1K
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

Area of Science:

  • Neurobiology
  • Ion Channel Physiology
  • Aging Research

Background:

  • Large-conductance calcium-activated potassium channels (BK channels) are crucial for regulating neuronal excitability in the mammalian nervous system.
  • BK channels modulate neuronal action potentials by controlling ion flow and membrane repolarization.

Purpose of the Study:

  • To investigate the role of BK channels in aging circadian clock neurons.
  • To understand how BK channel function changes with age in these specific neurons.

Main Methods:

  • The study by Farajnia et al. (2015) examines the function of BK channels.
  • Focuses on their involvement in circadian clock neurons within the context of aging.

Main Results:

  • BK channels are activated by membrane potential and intracellular calcium.
  • Their activity leads to membrane repolarization and controls cellular excitability.

Conclusions:

  • The findings are relevant to understanding neuronal aging.
  • Highlights the importance of BK channels in age-related changes in circadian clock neurons.
