Treatment of cervical cancer by electrochemotherapy with bleomycin, cisplatin, and calcium: an in vitro experimental study

Low-dose chemotherapy in advanced stages of cancer does not give a positive response in treatment. The use of high-dose antineoplastic drugs creates significant side effects. The limiting situation in treatment creates a need for new generation drugs with less side effects and new treatment methods that will enable low-dose drug use. Electroporation (EP), a phenomenon, is a technique in which the membrane permeability is increased by the establishment of hydrophilic pores in the cell membrane with short and high-voltage electrical pulses. In the present investigation study, we aimed to inspect the effects of EP plus bleomycin, cisplatin, and calcium administration (CaEP) on cell viability, apoptotic activity, gene expression p53, Bax/Bcl-2 rate mitochondrial membrane potential (ΔΨm), and cell cycle in HeLa cervical cancer cell line. The permeabilization of the membrane was evaluated in flow cytometry with the PI method, and cell viability was measured in an ELISA reader with the WST-8 method. For bleomycin and cisplatin doses applied to HeLa cells, the concentration values (IC
