| Research Abstract |
The QG56 cell, which was established from a lung squamous cell carcinoma, with CHFR inactivation due to aberrant methylation was transfected the CHFR expression vector (QG56+). QG56+cells showed suppressed tumor growth rate and cellular motility with statistical significances, and decreased a ratio of multinucleated cells or cells with bizarre nuclei compared with control cells (QG56－) (QG56－24.4%, QG56+3.6%, p<0.05). In flow cytometric analysis, a ratio of aneuploid cells tended to decrease (QG56－10.1%, QG56+1.8%, p=0.08). Our study suggested that retrieval of CHFR expression in NSCLC cells with CHFR loss suppresses tumor aggressiveness. Based on this result, CHFR abnormality might be a therapeutic target.
