The aim of Laboratory for Promotion of Advanced Research (LPAR) is to contribute to promoting the basic and clinical research through utilization of instruments in ARFS and inter-departmental collaboration. One of our collaborative topics is the dysfunction of the cell cycle regulators, which could cause several human diseases including cancers and chronic disorders.
