ABSTRACT
Aim To investigate the effect of rapamycin on proliferation, migration, and invasion of squamous cell carcinoma A431 cells in vitro. Methods Human squamous cell carcinoma A431 cells were cultured in vitro. MTT assay was used to investigate proliferation of A431 cells treated by rapamycin at different concentra-tions of (5,10,20 nmol·L-1). Wound healing and transwell assay were performed to detect migration and invasion of A431 cells treated by rapamycin, respec-tively. Reverse transcription PCR ( RT-PCR ) and Western blot were used to determine the expression of the osteopontin ( OPN ) in A431 cells at mRNA level and protein level, respectively. Results Rapamycin significantly increased the inhibitory rates of prolifera-tion and inhibited the migration and invasion of A431 cells in vitro. Furthermore, rapamycin treatment re-duced the expression of OPN in A431 cells. Conclu-sions Rapamycin can inhibit the migration and inva-sion of A431 . The intrinsic mechanism of rapamycin might be related to the down-regulation of the OPN ex-pression.
