Spatial and temporal aspects of ROS regulation, including mitochondrial versus cytosolic ROS effects on PI3K/Akt and NF-κB pathways and acute versus chronic ROS exposure outcomes, have been underexplored.
Quoted textsource-backed
Specifically, the spatial and temporal aspects of ROS regulation (i.e., the distinct effects of mitochondrial versus cytosolic ROS on the PI3K/Akt and NF-κB pathways, and the differential cellular outcomes driven by acute versus chronic ROS exposure) have been underexplored.
Specific contributions of ROS-generating enzymes such as NOX isoforms and xanthine oxidase to tumor microenvironment remodeling and immune modulation remain poorly understood.

Additionally, the specific contributions of ROS-generating enzymes, like NOX isoforms and xanthine oxidase, to tumor microenvironment remodeling and immune modulation remain poorly understood.
The precise context-dependent mechanisms by which ROS modulate oncogenic signaling, therapeutic response, and tumor microenvironment dynamics remain unclear.

Despite advances, precise context-dependent mechanisms by which ROS modulate oncogenic signaling, therapeutic response, and tumor microenvironment dynamics remain unclear.
Reactive oxygen species have paradoxical roles in cancer progression, with evidence supporting both tumor-promoting and tumor-inhibiting effects.

Reactive oxygen species (ROS) are often seen solely as harmful byproducts of oxidative metabolism, yet evidence reveals their paradoxical roles in both promoting and inhibiting cancer progression.
ROS concentration, localization, and persistence dictate whether ROS support tumor progression or induce cancer cell death.
Quoted textsource-backed
the complex interplay between ROS concentration, localization, and persistence is elucidated, revealing how these factors dictate the paradoxical support of tumor progression or induction of cancer cell death
Antioxidant mechanisms including NRF2-mediated responses may undermine the efficacy of ROS-targeted therapies.
