2016
The social amoeba Dictyostelium discoideum undergoes a developmental transition into a multicellular organism when starved. The evolutionary conserved protein coronin A plays a crucial role in the initiation of development. Using aggregation assays as our main method, we aim to elucidate the role of coronin A in early development.

Metabolic States of the Body: Fasting and Starvation
0 Views •
2024
During the initial hours of fasting, the body uses up its glycogen stores as an energy source. Once these glycogen reserves are depleted, the body begins breaking down stored triglycerides and structural proteins. During this stage, glycerol becomes a key substrate for gluconeogenesis, while free fatty acids undergo beta-oxidation to provide energy for tissues, such as skeletal muscle. In the fasting state, the body spares protein breakdown as much as possible to conserve muscle and structural...

Here, we describe a robust protocol for human cardiomyocyte derivation that combines small molecule-modulated cardiac differentiation and glucose deprivation-mediated cardiomyocyte purification, enabling production of purified cardiomyocytes for the purposes of cardiovascular disease modeling and drug screening.
FAQs
The omitted component determines which nutritional stress the experiment models. Removing carbon limits a major resource for growth and metabolism, whereas reducing nitrogen or amino acids creates a different deprivation profile; serum withdrawal provides another controlled condition in mammalian cells. Matching the omission to the biological question helps connect observed changes to a specific resource rather than to nutrient loss in general.
Nutrient withdrawal can reshape metabolism and activate cellular stress responses rather than merely reducing proliferation. Depending on the system and depleted resource, cells may alter survival strategies, regulate progression through the cell cycle, or activate autophagy, a process associated with cellular adaptation during deprivation. These responses reveal how cells maintain function when essential inputs become limited.
The duration of deprivation influences whether cells show temporary adaptation, slowed growth, or more substantial functional changes. Recovery conditions provide a way to examine whether those effects persist after nutrients return. Controlling both phases helps researchers interpret responses in relation to the starvation period and separate reversible adaptation from outcomes associated with prolonged nutritional stress.
They can compare responses across defined nutrient omissions while controlling exposure duration and subsequent recovery. If changing the depleted component produces different outcomes, the pattern can be related more specifically to that resource. Recovery observations add another layer of interpretation, helping distinguish regulated nutritional responses from changes that reflect broad loss of cellular function.
The medium’s nutrient composition, the length of exposure, and the conditions used for recovery should be specified and kept consistent. Researchers also need to identify whether carbon, nitrogen, amino acids, or serum is being reduced or omitted. This controlled design makes comparisons more meaningful and links measured changes to the intended deprivation condition.
Starvation-medium studies can be applied to bacteria, other microorganisms, and mammalian cells, allowing comparisons of nutritional adaptation across biological systems. In biology research, the approach supports questions about survival strategies, metabolic adjustment, cell-cycle regulation, autophagy, and signaling pathways. The specific system determines which deprivation condition and response are most informative.
Measurements from these experiments can show changes in growth, metabolism, survival behavior, cell-cycle regulation, autophagy, and signaling. Together, these outcomes indicate how an organism or cell responds when a required resource is withdrawn. Comparing responses across nutrient conditions and recovery phases can also clarify which adaptations are resource-specific and which are more general.
