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.
