Cancer testis antigens SEMG1 and SEMG2 (semenogelins 1 and 2) are the main proteins of human seminal fluid and are also expressed in malignant neoplasms of various origins. The biological role of semenogelins in the reproductive process is well understood, but almost nothing is known about their functions in tumor cells. In the present study, we used Mia-Paca2 cell line with overexpression of SEMG1 and SEMG2a as a cell model of human pancreatic cancer. Mia-Paca2 cells transduced with the corresponding vector served as control. Using flow cytometry and dihydroethidium (DHE) fluorescent agent detecting predominantly superoxide anion, we have shown that overexpression of SEMG1 and SEMG2 increases the ROS level. In addition, both semenogelins increased the susceptibility of tumor cells to the widely used chemotherapeutic genotoxic drugs doxorubicin and cisplatin. These findings showed that oncosuppressive properties are possessed by SEMG1 and SEMG2 in the cell model of pancreatic cancer. [ABSTRACT FROM AUTHOR] |
