Impact of Obesity and Lysosomal Dysfunction on Chemoresistance in Ovarian Cancer.
Biomedicines 2024 March 8
Obesity is recognized as a significant risk factor for ovarian cancer, with accumulating evidence highlighting its impact on disease progression and chemoresistance. This review synthesizes current research elucidating the link between obesity-induced lysosomal dysfunction and ovarian cancer chemoresistance. Epidemiological studies consistently demonstrate a positive correlation between body mass index (BMI) and ovarian cancer risk, attributed in part to the predilection of epithelial ovarian cancer cells for adipose tissue, particularly the omentum. Adipokines released from the omentum contribute to cancer-associated characteristics, including energy supply to cancer cells. Moreover, obesity-induced alterations in lysosomal function have been implicated in systemic inflammation and lipid metabolism dysregulation, further exacerbating cancer progression. Lysosomes play a crucial role in drug resistance, as evidenced by studies demonstrating their involvement in mediating resistance to chemotherapy in ovarian cancer cells. Recent findings suggest that pharmacological inhibition of lysosomal calcium channels sensitizes drug-resistant ovarian cancer cells to cisplatin treatment, highlighting the therapeutic potential of targeting lysosomal dysfunction in obesity-related chemoresistance. This review underscores the importance of understanding the multifaceted roles of lysosomes in obesity-related drug resistance and their implications for the development of targeted therapeutic interventions in ovarian cancer management.
