Abstract:
Objective:To study the role and mechanism of c myc ASODNS on cell expression of surface antigen of the tumor cells and susceptibility of target cells to immune cells attack.Methods:c myc mRNA was examined by RT PCR.MTT assay was usd to explore the effects of c myc ASODNS on PG cell sentisentity to lysis by CD 3AK effector cells.The expression of HLA ABC,ICAM 1,c myc protein was examined by flow cytometry.Results:When PG cells were treated with ASODNS(1 ?mol/L) there was a markably reduction of expression of c myc protein.Expression ratio of HLA ABC and ICAM 1 surface antigen expression ratio of PG cells were enhanced from 68.44%,38.44% to 83.16% and 42.09% respectively( P
