Circadian Rhythms and Gene Regulation

Circadian Rhythms and Gene Regulation

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...

Alveolates are a group of organisms recognized by the presence of alveoli, which are cytoplasmic sacs located beneath the cell membrane. While their function remains uncertain, alveoli may help regulate water balance by controlling how much water enters and leaves the cell. In dinoflagellates, these structures may serve as armor plates. There are three major types of alveolates: ciliates, which move using cilia; dinoflagellates, which use flagella for movement; and apicomplexans, which are...

Biological Clocks and Seasonal Responses

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.

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...

Symbiosis

Symbiosis

Symbiotic relationships are long-term, close interactions between individuals of different species that affect the distribution and abundance of those species. When a relationship is beneficial to both species, this is called mutualism. When the relationship is beneficial to one species but neither beneficial nor harmful to the other species, this is called commensalism. When one organism is harmed to benefit another, the relationship is known as parasitism. These types of relationships often...

Predator-Prey Interactions

Predator-Prey Interactions

Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.

Area of Science:

Chronobiology
Parasitology
Molecular Biology

Background:

Circadian clocks in multicellular organisms are well-understood.
Biological rhythms in parasites, their regulation, and fitness consequences are largely unknown.
Malaria (Plasmodium) parasites exhibit developmental rhythms during host replication and vector transmission.

Purpose of the Study:

To explore the generation of periodicity in parasite traits.
To investigate the fitness consequences of biological rhythms in parasites.
To understand the connection between parasite rhythms and host/vector daily cycles.

Main Methods:

Focus on malaria (Plasmodium) parasite systems.
Analysis of developmental rhythms during host blood-stage replication.
Investigation of rhythms during parasite transmission to vectors.

Main Results:

Rhythmic parasite replication in hosts influences inflammatory responses and disease severity.
Parasite rhythms impact disease symptoms and transmission efficiency.
Rhythmic parasite activity confers tolerance to anti-parasite drugs.

Conclusions:

Understanding parasite biological rhythms is crucial for disease management.
Timing and synchrony of parasites with host/vector rhythms are key to fitness.
Knowledge of these rhythms can optimize anti-parasite therapies for efficacy and reduced host toxicity.
