What is FACS?
FACS stands for fluorescence-activated cell sorting, a technique used to isolate specific cell types based on their fluorescence characteristics.
What is CUT&RUN?
CUT&RUN is a method used to study protein-DNA interactions in cells, allowing for precise mapping of transcription factor binding sites.
Why are nuclear receptors important?
Nuclear receptors play critical roles in regulating gene expression and are involved in various physiological processes, including metabolism and development.
How does the androgen receptor affect muscle function?
The androgen receptor is essential for the differentiation and function of myofibers, influencing their contractile and metabolic properties.
