Abstract
There is evidence that propolis exhibits anti-inflammatory, anticancer, and antioxidant properties. We assessed the potential beneficial effects of Brazilian propolis on liver injury in nonalcoholic fatty liver disease (NAFLD). Our findings demonstrate that Brazilian propolis suppresses inflammation and fibrosis in the liver of mice with NAFLD by inhibiting the expression of genes involved in endoplasmic reticulum (ER) stress. Additionally, Brazilian propolis also suppressed the expression of ER stress-related genes in HepG2 cells treated with an excess of free fatty acids, leading to cell apoptosis. A deeper analysis revealed that kaempferol, one of the components present in Brazilian propolis, induces cell proliferation through the mitogen-activated protein kinase (MAPK)/extracellular signal-regulated kinase (ERK) pathway and protects against oxidative stress. In conclusion, Brazilian propolis exhibits hepatoprotective properties against oxidative stress by inhibiting ER stress in NAFLD-induced model mice.
期刊介绍：
Biological and Pharmaceutical Bulletin (Biol. Pharm. Bull.) began publication in 1978 as the Journal of Pharmacobio-Dynamics. It covers various biological topics in the pharmaceutical and health sciences. A fourth Society journal, the Journal of Health Science, was merged with Biol. Pharm. Bull. in 2012.
The main aim of the Society’s journals is to advance the pharmaceutical sciences with research reports, information exchange, and high-quality discussion. The average review time for articles submitted to the journals is around one month for first decision. The complete texts of all of the Society’s journals can be freely accessed through J-STAGE. The Society’s editorial committee hopes that the content of its journals will be useful to your research, and also invites you to submit your own work to the journals.
