Abstract:
Objective To investigate the impacts of LASP-1 on the behavior and cell proliferation ability of tumor derived osteoblast-like cells and non tumor derived osteoblasts. Methods QRT-PCR and Western blot were performed to detect LASP-1 expressions in mouse bone marrow mesenchymal stem cells(BMMSC),human osteoblasts (hOB) and human osteosarcoma cell (MG-63). With the construction of recombinant vector and the transfection of shLASP-1,the expression changes in both LASP-1 and osteocalcin(OCN),and the cell number of cell-cycle phase distribution were analyzed. Results With up-or down-regulation of LASP-1,osteocalcin(OCN) expression,cell proliferation ability and the cell number of G2/M phase in non tumor cells(BMMSC,hOB)had no obvious changes. However,as for the tumor cells(MG-63),with an increased expression of LASP-1,the expression of OCN,cell proliferation number and the cell number at G2/M phase changed. There was no significant effect on the moving ability of each cell. Conclusions LASP-1 has no significant effect on the osteogenic proper-ties,cell proliferation ability and cell cycle distribution of non tumor derived cells,but has a regulatory effect on tumor derived cells(MG-63).
