Key result
VNN1 knockdown protects cardiac myoblasts from hypoxia-reoxygenation injury by activating the PI3K/Akt pathway.
Why the study?
Myocardial ischemia/reperfusion injury causes cardiomyocyte death through oxidative stress and inflammation, and the role of VNN1 in this process is unclear.
Knockdown of VNN1 protects cardiac myoblasts from hypoxia/reoxygenation injury by activating the PI3K/Akt signaling pathway.
VNN1 knockdown may protect myoblasts in vitro; leaves open whether it offers a viable therapeutic target in clinical ischemia-reperfusion.
Myocardial ischemia/reperfusion (I/R) injury is a critical factor contributing to adverse outcomes following infarction, primarily due to oxidative stress, inflammation, and cardiomyocyte death. Vanin-1 (VNN1), a pantetheinase enzyme involved in redox regulation, has recently emerged as a potential mediator of tissue damage under stress conditions. This study aimed to investigate the role of VNN1 in hypoxia/reoxygenation (H/R)-induced injury in H9c2 cardiomyocytes and to explore the involvement of the PI3K/Akt axis. An

Hu et al. (2026) studied Hypoxia/reoxygenation (H/R) injury. shVNN1 transfection (VNN1 knockdown) vs. shNC (negative control) was evaluated on Activation of PI3K/Akt signaling pathway (p-PI3K/PI3K and p-Akt/Akt ratios) (p=< 0.01). Knockdown of Vanin-1 (VNN1) activates the PI3K/Akt signaling pathway under hypoxia/reoxygenation injury in H9c2 cells, an effect reversed by H₂O₂ treatment.
