Abstract:
The diverse repertoires of cellular mechanisms that progress certain cancer types are being uncovered by recent research and leading to more effective treatment options. Ovarian cancer (OC) is among the most difficult cancers to treat. OC has limited treatment options, especially for patients diagnosed with late-stage OC. The dysregulation of miRNAs in OC plays a significant role in tumorigenesis through the alteration of a multitude of molecular processes. The development of OC can also be due to the utilization of endogenously derived reactive oxygen species (ROS) by activating signaling pathways such as PI3K/AKT and MAPK. Both miRNAs and ROS are involved in regulating OC angiogenesis through mediating multiple angiogenic factors such as hypoxia-induced factor (HIF-1) and vascular endothelial growth factor (VEGF). The NAPDH oxidase subunit NOX4 plays an important role in inducing endogenous ROS production in OC. This review will discuss several important miRNAs, NOX4, and ROS, which contribute to therapeutic resistance in OC, highlighting the effective therapeutic potential of OC through these mechanisms.
Insights
This review explores microRNAs (miRNAs) and reactive oxygen species (ROS) in ovarian cancer (OC). Understanding their roles in therapeutic resistance could lead to novel OC treatment strategies.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Ovarian cancer (OC) presents significant treatment challenges, particularly in late stages.
- MicroRNA (miRNA) dysregulation and reactive oxygen species (ROS) are implicated in OC development and progression.
- Signaling pathways like PI3K/AKT and MAPK are activated by ROS, contributing to tumorigenesis.
Purpose of the Study:
- To review the roles of specific miRNAs, NOX4, and ROS in ovarian cancer.
- To elucidate their contribution to therapeutic resistance in OC.
- To highlight potential therapeutic strategies targeting these mechanisms.
Main Methods:
- Literature review of current research on miRNAs, NOX4, and ROS in OC.
- Analysis of molecular mechanisms underlying OC progression and therapeutic resistance.
- Discussion of angiogenic factors like HIF-1 and VEGF in OC.
Main Results:
- miRNAs and ROS significantly influence OC tumorigenesis and angiogenesis.
- NOX4 is a key mediator of ROS production in OC.
- These factors contribute to therapeutic resistance in ovarian cancer.
Conclusions:
- Targeting specific miRNAs and ROS pathways, including NOX4, shows promise for overcoming OC therapeutic resistance.
- Further research into these mechanisms could yield effective new treatments for ovarian cancer.
- Understanding miRNA and ROS interplay is crucial for advancing OC therapy.
