To explore the existence,distribution of prohibitin in nuclear matrix and the co-localization relationship between prohibitin and the products of some interrelated genes in the human osteosarcoma MG-63 cells before and after HMBA treatment, the nuclear matrix of MG-63 cells and the cells induced by HMBA were selectively extracted. It was confirmed by Western blot that prohibitin existed in the component of nuclear matrix protein of MG-63 cells and its expression was decreased by HMBA treatment. The immunofluorescence observation revealed that prohibitin located in the nuclear matrix, and its distribution regions and expression level had altered after HMBA treatment. The co-localization and its alternation of distributive area in the cells treated by HMBA were observed between prohibitin and the products of oncogenes or tumor repression genes including c-fos, c-myc, p53 and Rb by using laser scanning confocal microscopy. The results of this study demonstrated that prohibitin was a kind of nuclear matrix protein, and locacted in the nuclear matrix,and the distribution and expression of prohibitin and its relationship with associated genes play an important role during the differentiation of MG-63 cell.
