Research in our department encompasses all levels of genetic analysis on oncogenesis, including studies aimed at understanding the molecular and genetic mechanisms of oncogenesis. A primary focus is on the structure and function study of Double minutes chromsome (DMs). Otherwise, as one of the three major national centers participating in the Chinese Human Genome Project (CHGP), we were committed to preserving the genetic resource of Chinese minority populations with the goal of exploring their genetic diversity and investigating the association of genetic variants in human diseases.
