Epigenetic Regulation

2019
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer. In most mammals, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY). The X chromosome contains significantly more genes than the Y chromosome. Therefore, to prevent an excess of X chromosome-linked gene expression in females, one of the two X chromosomes is randomly silenced during early development.

Master Transcription Regulators
0 Views •
2020
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

We describe an ovarian fad pad transplantation assay suitable for studies of normal and transformed epithelia of the female reproductive tract. The mouse fat pad allows transplantation of large tissue fragments, is easily accessible for surgery and imaging, and provides the most favorable native environment for tissues of Müllerian origin.

Using an ex vivo explant model, small pieces of the rostral portion of visceral white adipose tissue from lean mice are cultured for 7–10 days, enabling the induction and study of adipose tissue inflammation as it occurs during high-fat diet feeding.
FAQs
The phenotype reflects how strongly coordinated processes favor lipid storage or release. Lipid uptake and de novo synthesis can increase the supply of lipids to adipocytes, while hormone- and signal-mediated lipolysis mobilizes stored lipids. The resulting balance influences adipose tissue function, whole-body energy balance, and how organisms use available energy under different conditions.
Genetic factors and environmental conditions can shift the activities that control lipid uptake, synthesis, storage, and lipolysis. Nutrition and activity are environmental influences specifically relevant to these patterns, while genetic variation may alter the underlying regulation. Their interaction can produce differences in fat distribution and energy use among organisms or individuals.
Storage and lipolysis represent opposing but coordinated aspects of lipid regulation. Examining them separately helps researchers determine whether a phenotype is associated more strongly with lipid accumulation, impaired mobilization, or changes in both processes. This distinction clarifies how adipose tissue contributes to whole-body energy balance and supports comparisons among metabolic strategies.
Characterization can consider several linked features: lipid uptake, de novo synthesis, adipocyte storage, hormone- and signal-mediated lipolysis, fat distribution, and whole-body energy use. Evaluating this combination provides a functional view of adipose tissue rather than relying on a single visible trait. It also allows biologists to compare how organisms regulate lipids under different conditions.
These phenotypes are useful when researchers need to connect altered adipose tissue function with broader metabolic outcomes. Comparing patterns of storage, mobilization, distribution, and energy use can help investigate the cellular basis of obesity and other metabolic disorders. The same framework supports testing how nutrition, activity, or genetic variation changes lipid regulation.
In biology, the framework connects cellular lipid regulation with organism-level metabolism and development. Researchers can use it to compare metabolic strategies, examine how environmental or genetic changes alter energy use, and identify processes that may represent therapeutic targets. Its value comes from linking adipocyte behavior and signaling with changes in whole-body energy balance.
