Tangshen Formula Alleviates Hepatic Steatosis by Inducing Autophagy Through the AMPK/SIRT1 Pathway
Conclusion In conclusion, the present study demonstrated that autophagy was involved in relieving the effects of TSF against NAFLD, which were mediated by the AMPK/SIRT1 pathway (Figure 7D). These findings may improve our current understanding of the role of TSF in treating hepatic steatosis and provide an experimental basis for the clinical application of TSF in NAFLD and its related metabolic syndrome. Ethics Statement This study was carried out in accordance with the recommendations in the Guide for the Care and Use of Laboratory Animals of the National Institutes of Health. The protocol was approved by the Ethics Co...

Tripterygium glycoside protects diabetic kidney disease mouse serum-induced podocyte injury by upregulating autophagy and downregulating β-arrestin-1.
CONCLUSIONS: This study demonstrated that tripterygium glycoside provided protection against podocyte injury induced by high-glucose serum, and that this effect was mediated by the concomitant activation of autophagy and downregulation of β-arrestin-1.

Oxymatrine attenuates oxidized low ‑density lipoprotein‑induced HUVEC injury by inhibiting NLRP3 inflammasome‑mediated pyroptosis via the activation of the SIRT1/Nrf2 signaling pathway
Int J Mol Med. 2021 Oct;48(4):187. doi: 10.3892/ijmm.2021.5020. Epub 2021 Aug 9.ABSTRACTOxymatrine, a quinolizidine alkaloid isolated from the traditional Chinese herb Sophora flavescens Aiton, has been demonstrated to exert anti‑inflammatory and atherosclerotic effects, but the molecular mechanism has yet to be elucidated. Accumulating evidence indicates an important role of NLR family pyrin domain containing 3 (NLRP3) inflammasome‑mediated pyroptosis in the pathogenesis of atherosclerosis. The present study was undertaken to investigate whether oxymatrine attenuates oxidized low‑density lipoprotein (ox‑LDL)‑ind...

Auriculasin enhances ROS generation to regulate colorectal cancer cell apoptosis, ferroptosis, oxeiptosis, invasion and colony formation
Biochem Biophys Res Commun. 2021 Dec 1;587:99-106. doi: 10.1016/j.bbrc.2021.11.101. Online ahead of print.ABSTRACTColorectal cancer (CRC) is one of the most common malignant tumors in the digestive system, and Chinese herbal medicine plays an important role in tumor treatment. The in-depth study of auriculasin isolated from Flemingia philippinensis showed that auriculasin promoted reactive oxygen species (ROS) generation in a concentration-dependent manner; when ROS scavenger NAC was added, the effects of auriculasin in promoting ROS generation and inhibiting cell viability were blocked. Auriculasin induced CRC cell apopto...

Ephedrine induced Thioredoxin-1 expression through β-adrenergic receptors/Cyclic AMP/protein kinase A/dopamine- and Cyclic AMP-regulated phosphoprotein signaling pathway.
In this study, we found that Eph induced Trx-1 expression, which was inhibited by propranolol (β-adrenergic receptors inhibitor), but not by phenoxybenzamine (α-adrenergic receptors inhibitor) in rat pheochromocytoma PC12 cells. Moreover, the increase of Trx-1 expression was inhibited by SQ22536 (adenylyl cyclase inhibitor) and H-89 (protein kinase A inhibitor). Interestingly, the effect of Eph on dopamine- and Cyclic AMP-regulated phosphoprotein (DARPP-32) was similar to Trx-1. Thus, the relationship between Trx-1 and DARPP-32 was further studied. The DARPP-32 siRNA significantly reduced Trx-1 expression, but Trx-1 siRN...
