Nuclear Receptors Imaging Analysis

The nuclear receptor (NR) is a lipid-soluble ligand-dependent transcription factor that regulates the transcription of target genes through the activation of endogenous or exogenous substances, and is involved in the regulation of a variety of physiological functions. NRs are widely distributed in the body and regulate a wide range of drug metabolizing enzymes and transporters, which can have a significant impact on the absorption, distribution, metabolism and excretion of drugs in the body. Most of the target genes regulated by nuclear receptors are involved in the formation of tumor multidrug resistance, which may become a new drug target for reversing tumor multidrug resistance. Therefore, the imaging analysis of nuclear receptors is important for the development of nuclear receptor-related drugs.

Nuclear Receptors Imaging Analysis

The development of live cell imaging techniques has facilitated the study of nuclear receptor localization and mobility. Based on fluorescent proteins, researchers can monitor the behavior of nuclear receptors in their physiological environment directly in living cells. In addition, fluorescence recovery (FRAP), fluorescence correlation spectroscopy (FCS) and fluorescence resonance energy transfer (FRET) can be used to study nuclear receptor interactions and their dynamics.

CD BioSciences has been committed to the development of imaging technology for many years. We can use a fluorescence microscopy technique with single molecule sensitivity (fluorescence correlation spectroscopy) to study the regulation of ligand binding by nuclear receptors in living cells. In addition, we can also study the localization and mobility of nuclear receptors.
