DIVISION OF HOST DEFENSE:

Department of Cell Biology

Subjects:

  1. The role of heparin-binding EGF-like growth factor in development.
  2. The mode of actions of membrane-anchored growth factors.
  3. Ectodomain shedding mechanism of EGF family growth factor.
  4. Physiological role of CD9 and the tetraspanin family proteins.
  5. Epigenetics in germ cells: During germ cell differentiation, epigenetic information undergoes drastically changes. We are analyzing the molecular basis of the DNA methylation, histone modification and histone to protamine transition in spermatogenesis.
  6. Transcriptional regulation of germ cell specific genes: During male germ cell development, each differentiation step requires the expression of a specific set of precisely regulated genes. Some of these genes are exclusively expressed in male germ cells. We are characterizing the unique molecular mechanisms of the preinitiation complex formation for transcription in germ cells.
  7. Molecular basis and biological significance of epigenetical changes during germ cell differentiation.
  8. Transcriptional regulation of germ cell specific genes.
