Oncolytic Probiotics Mediated Ovarian Cancer Treatment

Ovarian cancer remains one of the most mortal gynecological malignancies in the world. Targeted therapy is a recent drug innovation and aims at blocking specific proteins or genes. Targeted therapy is predicted to be a less toxic and more effective than older forms of therapeutic strategy for ovarian cancer.

current main therapeutic targets of ovarian cancer.

Targeted therapy is different to non-specific treatments like chemotherapy that involves employment of non-specific intracellular toxins that inhibit the process of cell division. Targeted therapy could reduce the side- effects due anti-mitotic damage to the normal cells. Poly ADP ribose polymerase (PARP) inhibitors have recently garnered interest in ovarian cancer treatment. PARP inhibitors and anti-VEGF monoclonal antibodies have been approved for maintenance and treatment as effective targeted drugs for advanced or recurrent ovarian.
