AIM: Pancreatic stellate cells (PSCs) have a vital role in pancreatic fibrosis
accompanied by pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis
(CP). Any agents which can affect the activation of PSCs could become potential
candidates for treatment strategies in PDAC and CP. Our aim was to explore the
effect of Coenzyme Q10 (CoQ10) in the process of PSCs activation. METHODS:
Isolated PSCs from C57BL/6 mice were treated with various dosages of CoQ10 (1,
10, and 100?M) and different time (24h, 48h, and 72 h). Effect of CoQ10 on
autophagy, apoptosis, senescence and oxidative stress, as well as the activation
of PSCs were analyzed by immunocytofluorescent staining, quantitative real time
RT-PCR, western blotting, SA-?-galactosidase staining, malondialdehyde and
reactive oxygen species (ROS) assay. RESULTS: Expression of ?-smooth muscle
actin, LC3II, Beclin1, Cleaved caspases-3 and Bax levels were significantly
reduced in CoQ10 treatment groups. Meanwhile, compared with the control group,
significant differences for the expression of desmin, P62, Bcl-2, p-PI3K, p-AKT
and p-mTOR levels in CoQ10 treatment groups were found. Moreover, CoQ10 affected
the secretion of extracellular matrix components for PSCs. Few SA-?-gal positive
cells were found in CoQ10 treated groups. A significant decrease in ROS positive
cells and malondialdehyde levels were observed after 72 h exposure to CoQ10.
CONCLUSIONS: Our finding suggests that CoQ10 inhibits the activation of PSCs by
suppressing autophagy through activating the PI3K/AKT/mTOR signaling pathway.
CoQ10 may act as a therapeutic agent in PSC-relating pathologies and/or
anti-fibrotic approaches.
