Research Progress of Epigenetic Modification on the Regulation of Transporters Under Hypoxia

Epigenetic modification refers to the heritable changes caused by chromosomal changes without changing the DNA sequence. Epigenetics runs through the entire growth and differentiation process of the body, which causes varied diseases. Hypoxia is a physiological astate of lowered partial oxygen partial pressure that affects cell and tissue function. Transporters are proteins that maintain a normal and stable state of cells. Transporter's expression levels when hypoxia occurs influence the absorption, distribution, metabolism, and excretion of drugs, thereby affecting the utilization and efficacy of drugs. Epigenetic modification is assumed to play an important role in the metabolism of drugs. Changes in epigenetic modification and transporter expression levels under hypoxia are explored in our work, and the effect of epigenetic modification on transporter expression and how this regulatory mechanism works and affects drugs under hypoxia are questioned. It is important for drug development, treatment of diseases and rational use of drugs.
