Abstract:
Objective To construct a whole-cell vaccine modified by mice HSP70 and GM-CSF in prostate cancer. Methods Sequence fragments carrying mice Hspa1a coupled with C-myc or Csf2 coupled with V5 tag were constructed by chemical synthesis and PCR amplification , then both fragments were cloned into the vector pMD-18T. After se quencing, fragments described above were cloned into pLenti6.3_MCS lentiviral vector. The lentiviral expression vectors were named as pLenti6.3_MCS_Hspa1a_cMyc and pLenti6.3_MCS_Csf2_V5. These vectors were transfected or co-transfected into mice prostate cancer cell line RM-1 and proteins were detected by Western blotting. Following irradia-tion of 10 Gy, cells lost proliferative ability and were frozen and then stored. Results Recombinant lentiviral vectors pLenti6.3_MCS_Hspa1a_cMyc and pLenti6.3_MCS_Csf2_V5 were successfully constructed and GM-CSF, HSP70 or both expression in the transfected RM-1 cells were verified by Western blotting. Conlusion The RM-1 whole-cell vaccines modified by HSP70 and GM-CSF have been successfully constructed, which facilitate further investigation of the action mechanisms of whole-cell antigen and immune enhancement.
