Abstract:
Recent advancements in ovarian cancer treatment, particularly with PARP inhibitors, have markedly enhanced the recurrence-free interval, shifting the treatment paradigm and increasing treatment success in patients with BRCA mutations or HRD (homologous recombination deficiency). However, a significant proportion of cases experience relapse, resulting in poorer long-term survival rates when compared to other female cancers, such as breast cancer. This review explores the potential of adeno-associated virus (AAV) vectors for gene therapy in ovarian cancer and examines rational gene therapy strategies by categorizing them based on target cells and target genes to determine the most effective approach for ovarian cancer treatment. Specifically, it examines strategies such as anti-angiogenesis and immune modulation, highlighting the strategy of gene supplementation to hinder ovarian cancer progression. Innovations in AAV capsid design now allow for targeted delivery, focusing on ovarian cancer stem cells (CSCs) identified by specific markers. Additionally, leveraging DNA sequencing technologies enhances the identification and incorporation of therapeutic genes into AAV vectors, promising new avenues for ovarian cancer gene therapy.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
