Inhibition of hepatitis B virus production by Boehmeria nivea root extract in HepG2 2.2.15 cells. (1/9)
AIM: To explore the anti-hepatitis B virus (HBV) effects of Boehmeria nivea (B. nivea) root extract (BNE) by using the HepG2 2.2.15 cell model system. METHODS: Hepatitis B surface antigen (HBsAg), hepatitis B virus e antigen (HBeAg), and HBV DNA were measured by using ELISA and real-time PCR, respectively. Viral DNA replication and RNA expression were determined by using Southern and Northern blot, respectively. RESULTS: In HepG2 2.2.15 cells, HBeAg (60%, P < 0.01) and particle-associated HBV DNA (> 99%, P < 0.01) secretion into supernatant were significantly inhibited by BNE at a dose of 100 mg/L, whereas the HBsAg was not inhibited. With different doses of BNE, the reduced HBeAg was correlated with the inhibition of HBV DNA. The anti-HBV effect of BNE was not caused by its cytotoxicity to cells or inhibition of viral DNA replication and RNA expression. CONCLUSION: BNE could effectively reduce the HBV production and its anti-HBV machinery might differ from the nucleoside analogues.

(+info)'Boehmeria' is a genus of flowering plants in the nettle family (Urticaceae). It includes several species of herbaceous perennials and shrubs, some of which are known for their use in textile production. The most well-known species is Boehmeria nivea, also known as ramie or China grass, which has been cultivated for its strong and durable bast fibers. These fibers are obtained from the inner bark of the plant's stems and can be used to make a variety of textiles, including clothing, canvas, and paper.
It is worth noting that while Boehmeria plants have some medicinal properties, they are not commonly used in modern medicine. Some species have been used in traditional medicine to treat various ailments such as skin irritations, fever, and diarrhea, but there is limited scientific evidence to support these uses.
Therefore, the medical definition of 'Boehmeria' would be a genus of plants in the nettle family that includes species with some medicinal properties, although they are not widely used in modern medicine.
