Effects of curcumin on NF-κB, AP-1, and Wnt/β-catenin signaling pathway in hepatitis B virus infection.

Curcumin is a yellow-orange powder derived from the Curcuma longa plant. Curcumin has been used extensively in traditional medicine for centuries. This component is non-toxic and shown different therapeutic properties such as anti-inflammatory, anti-cancer, antiviral, anti-bacterial, anti-fungal, anti-parasites, and anti-oxidant. Hepatitis B virus (HBV) is a small DNA member of the genus Orthohepadnavirus (Hepadnaviridae family) which is a highly contagious blood-borne viral pathogen. HBV infection is a major public health problem with 2 billion people infected throughout the world and 350 million suffering from chronic HBV infection. Increasing evidence indicated that curcumin as a natural product could be employed in the treatment of HBV patients. It has been showed that curcumin exerts its therapeutic effects on HBV patients via targeting a variety of cellular and molecular pathways such as Wnt/β-catenin, Ap1, STAT3, MAPK, and NF-κB signaling. Here, we summarized the therapeutic effects of curcumin on patients who infected with HBV. Moreover, we highlighted main signaling pathways (eg, NF-κB, AP1, and Wnt/β-catenin signaling) which affected by curcumin in HBV infections.
