Abstract

This research investigates the interplay between Reactive Oxygen Species (ROS) and Apelin (APLN) in regulating autophagy, with implications for placental cell senescence and apoptosis in pre-eclampsia (PE). We manipulated APLN expression using sgRNA to study its effects on ROS levels and subsequent cellular responses. Our findings reveal that APLN overexpression elevates ROS production, accelerating cellular senescence and apoptosis. In contrast, silencing APLN enhances autophagy, thereby diminishing cellular aging and apoptosis. These outcomes were confirmed

Research summary

The paper investigates the role of Apelin and Reactive Oxygen Species in autophagy and cell senescence, which are processes closely related to aging and cellular health. However, the focus on pre-eclampsia, a pregnancy-related condition, limits its broader applicability to general aging research. While the findings contribute to understanding cellular mechanisms that could relate to aging, they do not directly address root causes of aging or lifespan extension, making the impact relatively modest.
