Azurin protein of
Pseudomonas aeruginosa
is an anti-tumor agent against breast cancer and mammaglobin-A (MAM-A) protein is a specific antigen on the surface of MCF-7 for induction of cellular immune. The purpose of the present study was to investigate the effects of simultaneous expression of
azurin
and human
MAM-A
genes on the mRNA expression level of apoptosis-related and cell cycle genes in MCF-7 breast cancer cell line. The recombinant or empty plasmids were separately transferred into MCF-7 cells using Lipofectamine reagent. Flow cytometry was done to detect cell death and apoptosis. The expression of
azurin and MAM-A
genes were evaluated by IF assay, RT-PCR and western blot methods. Finally, apoptosis-related and cell cycle genes expression was examined in transformed and non-transformed MCF-7 cells by qPCR method. The successful expression of
azurin
and
MAM-A
genes in the MCF-7 cell were confirmed by RT-PCR, IF and western blotting. The apoptosis assay was showed a statistically significant (
p
< 0.05) difference after transfection. The expression of
BAK
,
FAS
, and
BAX
genes in transformed cells compare with non-transformed and transformed MCF-7 by pBudCE4.1 were increased statistically significant (
p
< 0.05) increases. Although, the increase of
SURVIVIN
and
P53
expressions in transformed cells were not statistically significant (
p
> 0.05). Co-expression of
azurin
and
MAM-A
genes could induce apoptosis and necrosis in human MCF-7 breast cancer cells by up-regulation of
BAK
,
FAS,
and
BAX
genes. In future researches, it must be better the immune stimulation of pBudCE4.1-azurin-MAM-A recombinant vector in animal models and therapeutic approaches will be evaluated.
